Luke Tornquist	7ce422417b	fix(mesh): expire dead peer records and instrument mesh boot (#8503) ... ## Summary Relay pods can stall in the `mesh_boot` startup step, and the mesh peer table grows without limit. One prod pod held 7,793 peer records. Most of those records belong to pods that no longer exist. **Cause.** Every boot gets a fresh runtime id, so a restarted pod leaves its old record behind. Nothing ever removed records, and scuttlebutt gossip kept spreading the dead ones around the fleet. Each reconcile pass, including the first one inside `boot_mesh`, then dials every record one at a time. This PR makes dead records expire. It also adds the measurements we need to see the next stall directly. ### Peer-table lifetime (`crates/buzz-relay-mesh/src/membership.rs`) - A peer record expires 5 minutes after its last heartbeat (`DEFAULT_PEER_RECORD_TTL`). For comparison, live runtimes refresh every 2s, and the Redis ready registry expires a silent runtime after 45s. - What happens to expired records: - They are **rejected on arrival**, so peers that haven't been upgraded can't re-add them. - They are **left out** of digests, deltas, and dial candidates. - They are **pruned** at the start of each reconcile pass. - Between prunes, they are not admitted (`has_peer`) and not routed (`peers`, `peer_has_capability`). - An expired entry that hasn't been pruned yet counts as absent, so any fresh record replaces it whatever its version. That lets a live peer's v1 Redis hint re-admit it before the next prune. - **The TTL never prunes or hides a peer with a live connection**, even if its heartbeat is stale. Its gossip can stop arriving while the transport stays up: a dead control stream, or a clock behind by more than the TTL. The connection proves the runtime is alive. Its stale record is still kept out of digests and dials. (The existing phi filter in `peers()` still drops a connected peer once its gossip stalls; this PR doesn't change that.) - **`Connected` tracks the transport map.** Because the TTL exemption trusts that flag, `install_peer` and `remove_peer` write it while holding the peers lock, so a connection that closes during install always ends `Disconnected`. A dial's `Connecting`/`Disconnected` writes are skipped when a connection is already installed, so a failed outbound dial can't overwrite a live inbound connection. Each reconcile pass also re-syncs the state from the transport map. - **Gossip no longer sets connection state.** Before, any gossiped record was marked `Connected`, even if this pod had never dialed it. That inflated the `/_mesh` counts. Now a record learned from gossip or the ready registry enters as `Disconnected`. Only the real connect and disconnect paths change the state. - Before building its candidate list, reconcile now skips peers that are already connected. A pass dials serially, and a dial to a dead runtime can take about a minute, so `dial_peer` re-reads the record before every address attempt. It stops once the record has expired or started draining, or once a connection has landed. ### Instrumentation - **`mesh_boot` sub-steps** use the existing startup-step gauges: `mesh_bind`, `mesh_publish`, and `mesh_initial_reconcile`. A pod stuck in `mesh_boot` now also shows which await it is stuck on. - **New metrics** (`crates/buzz-relay-mesh/src/telemetry.rs`): | Metric | Shows | |---|---| | `buzz_mesh_dial_total{outcome}` / `buzz_mesh_dial_duration_seconds` | Cost of each dial | | `buzz_mesh_reconcile_pass_seconds` | Full pass time | | `buzz_mesh_reconcile_candidates` | Dials planned for this pass (set after the registry scan) | | `buzz_mesh_peer_records{state,draining}` | Table size | | `buzz_mesh_peer_record_max_age_seconds` | Oldest heartbeat | | `buzz_mesh_peer_records_expired_total{reason=pruned\|rejected}` | Expiry activity | - The dial and pass histograms get buckets up to 600s. The default `_seconds` buckets stop at 5s, which would hide exactly the stall these metrics are meant to show. ### CI The `buzz-relay-mesh` tests and the `buzz-relay` `mesh_boot::tests` did not run in any CI lane. This PR adds both to `just test-unit`, and adds the matching stanzas to `scripts/run-tests.sh`. ### What got simpler - The peer table now has a defined size, about one record per live pod, where before it grew forever. - One wrong state write was deleted (gossip marking records `Connected`). - Two test suites that silently never ran now run. ### Rollout notes - Rejecting expired records works one pod at a time. During a rollout, pods that haven't been upgraded keep gossiping dead records. Upgraded pods reject them, which shows up as `reason="rejected"` on the expired counter. - A pod whose clock runs more than 5 minutes behind has all of its gossip rejected. It stays reachable through its Redis ready record and any live connection. A `reason="rejected"` count that keeps climbing outside a rollout points to that skew. - Upgraded pods leave expired records out of their digests. Pods that haven't been upgraded therefore resend the whole ghost set (about 7.8k records, roughly 1 MB) on every 2s gossip tick, on each old↔new connection. So during the rollout, `reason="rejected"` will climb by about the ghost count per tick per connection. This is expected and stops when the rollout finishes. ### Not in this PR The boot dial itself is still unbounded: it runs serially, has no per-dial timeout, and dials gossip-learned records. Bounding it changes how a pod joins the mesh, so it goes in a separate PR, and these metrics will measure it. ### Related issue None found. ### Testing - New tests: - `membership::tests`: expired gossip is rejected; prune drops only expired records; prune keeps a connected peer with a stale heartbeat; expired unconnected records are neither admitted nor routed before a prune; a fresh record replaces an expired, unpruned entry whatever its version; expired records are neither dialed nor gossiped before a prune; gossip never sets connection state; table stats. - `runtime::tests::reconcile_pass_publishes_dial_and_peer_table_metrics` - `runtime::tests::reconcile_pass_prunes_expired_peer_records` (binds the prune to the reconcile pass) - `runtime::tests::dial_skips_candidate_that_expired_after_the_pass_snapshot` - `runtime::tests::finishing_dial_does_not_overwrite_a_connection_that_landed` - `runtime::tests::connection_closed_during_install_ends_disconnected_and_expires` - `runtime::tests::reconcile_pass_resyncs_connection_state_from_transport` - `mesh_boot::tests::mesh_boot_sub_steps_name_the_step_that_failed` - Blox at `e06f55a4` (tree `866add1c`): `just fmt-check`, `just clippy`, `buzz-relay-mesh` nextest 3x, and the `buzz-relay` `mesh_boot`/`startup_steps`/`metrics` tests all pass. Three of the new tests fail against a mutant that removes the fix they pin (dial ignores expiry; dial state writes ignore the transport map; no reconcile resync). --------- Signed-off-by: Elrond <28d6302a099e5225b02c4155ac4236e4912603df2ab08dbfc2f4fef08ce598c8@buzz.block.builderlab.xyz> Co-authored-by: Elrond <28d6302a099e5225b02c4155ac4236e4912603df2ab08dbfc2f4fef08ce598c8@buzz.block.builderlab.xyz>	2026-10-26 09:47:30 -04:00
Bradley Axen	d676c7b8db	fix(deps): bump p256 to 0.14 for RUSTSEC-2026-0387 (#8592) ... ## Summary RustSec published [RUSTSEC-2026-0387](https://rustsec.org/advisories/RUSTSEC-2026-0387) against `crypto-bigint`. Some of its operations meant to be constant-time could compile to code that branches on secret values. Since the advisory came out, `cargo-deny check` reports advisories as failed. That breaks `Security Domain / Security` on `main` and on every PR that runs the Rust security job (for example #8575 and #8579). `crypto-bigint` 0.5.5 came in only through `p256` 0.13 → `elliptic-curve` 0.13 in `buzz-push-gateway`. The advisory has no 0.5.x fix; the patched line is 0.7.6+. This PR moves `buzz-push-gateway` to `p256` 0.14, which uses `crypto-bigint` 0.7.9. | Advisory | Crate | Change | |---|---|---| | [RUSTSEC-2026-0387](https://rustsec.org/advisories/RUSTSEC-2026-0387) | `crypto-bigint` | 0.5.5 → 0.7.9 (via `p256` 0.13.2 → 0.14.0) | **Code changes:** `p256` 0.14 renamed the SEC1 encoder from `ToEncodedPoint::to_encoded_point` to `ToSec1Point::to_sec1_point`. The gateway calls it in two places, both to re-encode an App Attest public key as uncompressed SEC1 bytes. The tests call it in five more. Nothing else in the gateway's API use changed. **Lockfile:** only the `p256` dependency chain changes: `ecdsa`, `elliptic-curve`, `ff`, `group`, `primeorder`, `rfc6979` and `sec1` move up a minor version. `primefield` and `wnaf` are added. The old `der`/`spki`/`pkcs8`/`pem-rfc7468`/`const-oid` 0.x versions that only this chain used are removed. `desktop/src-tauri/Cargo.lock` and the `buzz-feature-flags` fixture lockfile don't contain `crypto-bigint`, so they're unchanged. **Exposure, for context:** in production the gateway uses `p256` only to verify App Attest signatures against public keys. Signing with a private key happens only in tests. So the timing issue didn't realistically apply here, but the bump clears the advisory instead of ignoring it. ### Related issue N/A. I searched open and closed PRs for `RUSTSEC-2026-0387` and `crypto-bigint` and found none. ### Testing - `cargo-deny check`: `advisories ok, bans ok, licenses ok, sources ok`.

Since then, `cargo-deny check` fails on advisories. That breaks `Security Domain / Security` on `main` and on every PR that runs the Rust security job. | Advisory | Crate | Change | |---|---|---| | RUSTSEC-2026-0382 | `rustls-webpki` (distrusted intermediates) | 0.103.15 → 0.103.16 | | RUSTSEC-2026-0381 | `webpki-roots` (distrusted emSign roots) | 1.0.7/1.0.8 → 1.0.10 | | RUSTSEC-2026-0383 | `webpki-root-certs` (same roots) | 1.0.7/1.0.8 → 1.0.10 | This PR bumps all three in `Cargo.lock` and `desktop/src-tauri/Cargo.lock`.

It re-exports `webpki-roots` 1, which now resolves to the patched 1.0.10. `deny.toml` ignores RUSTSEC-2026-0381 for that shim and explains why. The ignore should come out once those consumers move to `webpki-roots` 1. ### Related issue N/A.

Luke Tornquist	039e1c8d59	feat(relay): write the NIP-43 member list in the membership transaction (#8482) ... ## Summary The relay-signed NIP-43 member list (kind:13534) was published after each membership change had already committed. If that publish failed, or if a change never republished at all (startup `bootstrap_owner`), the list stayed wrong until the background reconcile sweep found and fixed it. #8467 moved that sweep off the startup path. This PR removes the reason the sweep exists. Now every `buzz-db` function that changes `relay_members` writes the new list **in the same transaction**, as its last statement before commit: - It takes the per-community list lock last, reads the members, signs the list, retires the old one and inserts the new one. - If the list write fails, the membership change rolls back and the caller gets an error. - A call that changes nothing (already a member, role mismatch, host exists, limit reached) writes no list. The functions return `MembershipWrite<T> { outcome, snapshot }`. Callers push `snapshot` to live subscribers after commit. That push is the only thing left outside the transaction; if it fails, live clients see the change on their next fetch, and the stored list is already correct. Write paths covered (RPR #2, every write path): `add_relay_member`, `claim_relay_membership`, `claim_relay_invite`, `remove_relay_member`, `remove_relay_member_if_role`, `update_relay_member_role`, `bootstrap_owner` / `provision_owner`, `transfer_ownership`, `backfill_from_allowlist`, and the owner insert in `create_community_with_owner[_and_nip_fi_issuers]`. Community deletion removes the members together with the community, so it writes no list. The relay keypair is passed in explicitly instead of being stored on `Db`, so the compiler finds every caller. ### Behavior changes - **Open relays get an accurate list too.** Provisioning and ownership transfer used to publish only when `require_relay_membership` was on. The write is now unconditional. - **Same-second changes can't reuse an id.** The list's `created_at` is one second past the newest earlier list for that community, including retired ones, or the current time if that is later. Before, adding and then removing a member in the same second could produce an event with the same id as an earlier list. The insert then failed, and the stale list stayed live. A burst of changes can push `created_at` ahead of the clock by up to one second per change; it returns to the clock once the burst ends. - **`buzz-admin add-member` / `remove-member`** no longer build their own list (`publish_membership_list_with_bump` is deleted). They push the list the database wrote. Concurrent CLI runs now serialize on the database lock rather than depending on `run.sh` running one at a time. - **Owner mutations lock the community row `FOR NO KEY UPDATE`.** `transfer_ownership` and `bootstrap_owner` used `FOR UPDATE`. The list insert takes `FOR KEY SHARE` on that row through `events.community_id`'s foreign key, so a repair holding the list lock, or a removal or role update holding a member row, deadlocked with a concurrent owner change. `FOR NO KEY UPDATE` still conflicts with archive, unarchive and deletion admission, so the lifecycle ordering is unchanged. - **Startup delivers its list to other replicas.** When backfill or `bootstrap_owner` changes members at startup, the relay fans the newest list out through pub/sub once its state is ready, so clients connected to other replicas during a rolling deploy see an owner rotation without a refetch. - **New `buzz-admin republish-members`.** Rewrites the community's list from the stored members in one community-write transaction and pushes it live. This replaces the sweep as the repair for a list that is missing or stale: a `relay_members` change made directly in SQL, a restore, or a deployment that turns on `BUZZ_REQUIRE_RELAY_MEMBERSHIP` after running without it. ## Rollout Nothing rewrites a list automatically once the sweep is gone. A community whose list drifted before this deploys stays wrong until its next membership change or until an operator runs `buzz-admin republish-members`. Either deploy #8467 and let its sweep complete one pass first, or run `republish-members` for each community after this deploys. The command repairs only the community that `RELAY_URL` maps to, so on a relay hosting many communities, run it once per community host. ## What got simpler Deleted: - `reconcile_nip43_membership_snapshots`, `spawn_nip43_membership_reconciler`, its leader lock key and #8467's standby retry - the three `nip43_membership_snapshot_needs_reconciliation*` drift reads (one already deprecated) - `publish_nip43_membership_list` / `publish_nip43_membership_locked`, the separate after-commit republish at every call site, and `buzz-admin`'s duplicate publisher - the reconcile metrics `buzz_nip43_membership_reconciliations_total` and `buzz_nip43_membership_reconciliation_failures_total` - the after-commit publish metrics `buzz_nip43_membership_publications_total` and `buzz_nip43_membership_publication_seconds`, and the `publish_nip43_membership_locked` transaction metric label. A failed list write is now a failed membership write and shows up in the caller's existing error handling and the transaction metrics of its write path. - the `BUZZ_NIP43_RECONCILE_INTERVAL_SECS` setting There is now one way the list gets written, and it can't disagree with `relay_members` after commit. **Unused deploy config (outside this repo):** hosted deployments that set `BUZZ_NIP43_RECONCILE_INTERVAL_SECS` can drop it. It is now ignored. Dashboards or alerts on the four deleted metrics will stop receiving data. ## Testing New Postgres tests (`buzz-db`): - `relay_members::every_membership_write_commits_its_list`: for each write path, the returned list is the single live kind:13534 and names exactly the committed members. No-op calls return no list and leave the live list alone. - `relay_members::a_failed_list_write_rolls_back_the_membership_change`: holds the list lock, waits for the join to block on it, cancels that statement, and checks that the member was not added and the previous list is still live. - `relay_members::concurrent_joins_all_land_in_the_list`: 8 concurrent joins; the final list names all 8. - `relay_members::same_second_return_to_an_earlier_membership_writes_a_new_list`: add, remove, add, remove within a second; every list is newer than the last and no id repeats. - `relay_members::owner_transfer_and_list_repair_both_commit` and `relay_members::owner_transfer_and_member_removal_both_commit`: hold a repair (list lock) or removal (member row) open, wait until a transfer blocks behind it, then finish it. Both transactions commit; with `FOR UPDATE` back in place, one of them fails. - `community::create_community_with_owner_is_atomic_and_create_only` and `relay_invite::bounded_claim_exhausts_and_existing_member_retry_does_not_consume` now also check the list. Each new test was checked to fail against a mutation of the new code that brings back the old behavior (details in the thread). Stacked on #8467. Merge order: #8467, then #8468, then this. --------- Signed-off-by: Elrond <28d6302a099e5225b02c4155ac4236e4912603df2ab08dbfc2f4fef08ce598c8@buzz.block.builderlab.xyz> Co-authored-by: Elrond <28d6302a099e5225b02c4155ac4236e4912603df2ab08dbfc2f4fef08ce598c8@buzz.block.builderlab.xyz>	2026-10-20 11:39:13 -04:00
Will Pfleger	91e7b469b8	fix(relay): wait for the peer's Close before dropping any WebSocket (#8426) ... 🤖 A NIP-42 login refused for a NIP-FI key mismatch could reach the client as an abnormal close (`1006`, no reason) instead of the `NOTICE "restricted: authorization denied"` followed by close `1008` that every other authorization denial produces. The relay did write the NOTICE and the `1008` Close, but the connection task dropped TCP as soon as the writer finished, before the peer finished the close handshake. The client could then lose frames it hadn't read yet. It depends on timing, so it showed up intermittently and is not specific to key pairing. ## Relay route - `recv_loop` now hands back the read half even while a frame handler is still running. Frames are handled one at a time while the connection is live. Once it is cancelled, an in-flight handler (for example a Nostr `CLOSE` waiting on the subscription lock behind a REQ stuck in Redis) is spawned to finish instead of holding the reader. It is never dropped partway, so subscription retirement stays atomic, and cleanup joins it before the expiry barrier and application cleanup. - As soon as the writer finishes, `await_client_close` keeps the transport open until the client's Close arrives or the stream ends. It runs concurrently with joining the heartbeat, auth-timeout, expiry and auth-cancel tasks and the connection's application cleanup (subscriptions released, registry entry removed, presence cleared). Cleanup never waits on the peer, so a nonresponsive client cannot delay registry counts, presence or `has_admitted_connection`. The socket never waits on cleanup, so a stalled Redis (the pool has no wait timeout) or an expiry join blocked on its quiescence barrier cannot hold the socket and its file descriptor open past the bounded wait. The active-connection gauge and the connection permit are released after both finish. - The connection permit (`BUZZ_MAX_CONNECTIONS`) is now taken at the start of `handle_connection`, before the NIP-FI gate and the community-active bootstrap check, and held through the active handler or the refusal drain and its bounded wait. Previously a socket in bootstrap, or refused there, held no permit, so a burst of refusals could open sockets beyond the limit. Over the limit, the socket is still dropped with no frames. `buzz_ws_connections_active` still counts only connections that reached the active handler. ## Huddle-audio route - The relay and audio bootstrap drains share one bounded helper. A socket refused before admission waits after its community registry entry is released. - Every exit of the audio handler gets the bounded peer wait. Exits whose cleanup follows their terminal frames (`room_full`, `room_ended`, version mismatch, archived channel, owner rejection or unreachable, failed commit confirmation) and the normal teardown hand the socket to a background task that waits for the client's Close, so lease releases, `48102` writes and room archiving on Postgres and Redis never hold the socket open. The remaining exits send their frames last, and `handle_active_audio_connection` waits once they return. The wrapper joins the background task before returning, so the audio connection permit is held until the socket ends, as on the relay route. - Audio error exits now follow their existing JSON error with a Close frame: | Exit | Close code | | --- | --- | | `huddle_relay_draining` | `1012` service restart | | `join_rejected` (owner resolution failed), `huddle_owner_unreachable`, failed channel lookup | `1011` internal error | | `huddle_audio_unavailable`, `unsupported_version`, `upgrade_required`, `room_full`, `room_ended`, archived channel, owner rejection, NIP-FI authorization denial | `1008` policy | Audio login failures and authorization refusals outside NIP-FI `authorization_denied` still send only their existing error frame, then get the bounded wait. - The audio read half is an enum, so the hand-off has no `expect()` that can panic. ## Timing - The peer wait is bounded by `WS_TERMINAL_FLUSH_TIMEOUT` (1s), and drains to end-of-stream so a client-initiated Close gets its reply. The terminal writer flush has its own 1s budget, so the worst case for terminal transport work is about 2s per refused or closed socket. - Terminal frame writes (`flush_terminal_frames`, `send_exit_frames_bounded`) still give up on the first failure, but a failed or timed-out send is now logged at `debug` instead of being discarded. - The graceful-shutdown comment in `main.rs` now describes per-stage budgets (restart jitter, restart-Close acknowledgement, terminal flush, peer wait) rather than a per-socket total. The 30s hard drain bounds every socket, and the 35s process shutdown budget fits within the chart's 60s `terminationGracePeriodSeconds`. ## Tests Real-socket tests in the infra-free relay lane of `just test-unit` and `scripts/run-tests.sh` unless marked PostgreSQL: - The key-mismatch login and a session-expiry denial (as a control) both assert NOTICE then `1008` / `authorization denied` on the wire. - A raw-TCP client that never answers Close: the relay holds the socket for at least the bounded wait, has deregistered the connection by the time the socket ends, and ends it on its own under a 10s watchdog. - A raw-TCP client that withholds its Close until the connection has deregistered: the relay ends the socket in under the 1s cap, which fails if cleanup waits on the peer. - A raw-TCP client that never answers while final cleanup is stalled at a test pause point: the socket still ends after the bounded wait. - A raw-TCP client that never answers Close on the relay bootstrap drain, the audio bootstrap drain and an early audio-handler exit: the relay holds each socket for the bounded wait. - On the relay route with a one-slot budget through the real `handle_connection`: a refused bootstrap holds the slot until its socket ends, and a bootstrap stalled on the community check already holds the slot before the AUTH challenge is sent. - An established relay session whose reader is blocked in a Nostr `CLOSE` handler on a held subscription lock when the session expires: the socket ends within the bounded wait while the lock is held, and cleanup completes with the subscription retired once it is released. - An established relay session whose expiry task is stalled behind a held session effect permit: the socket still ends within the bounded wait. - PostgreSQL: an established audio session whose teardown is stalled after its Close, and a stalled archived-channel exit, both end within the bounded wait from the hand-off. - PostgreSQL: a fast refusal (unsupported protocol version) through the real `handle_audio_connection` with a one-slot permit budget keeps the permit taken until that socket ends. - PostgreSQL: `huddle_audio_unavailable` sends its error and then Close `1008` as the very next frame. --------- Signed-off-by: Will Pfleger <pfleger.will@gmail.com> Signed-off-by: Duncan <dcfd242e557282d7a1e2cf2e6877522682f1e5c6156dc92ca7d90eaedd3b0f95@buzz.block.builderlab.xyz> Co-authored-by: Duncan <dcfd242e557282d7a1e2cf2e6877522682f1e5c6156dc92ca7d90eaedd3b0f95@buzz.block.builderlab.xyz>	2026-10-19 16:13:27 -04:00

Without this, the relay can't keep up with bb-public, where new communities are created at every signup and a static `BUZZ_NIP_FI_COMMUNITIES` list won't do. **Source switch.** `BUZZ_NIP_FI_COMMUNITY_SOURCE=database` resolves each community's trusted issuers from `community_nip_fi_issuers`, filtered by the issuer registry, instead of the static list. Each community gets its own policy ID: the base ID no longer hashes every community audience, and the final ID hashes the base plus this community's audience, so policy IDs change once (see `docs/operator-nip-fi-bindings.md`). `Config::from_env` refuses to start, in every mode, on an unknown source, on `database` together with `BUZZ_NIP_FI_COMMUNITIES`, and on `database` without `BUZZ_NIP_FI_PROVISION_BINDING`. `BUZZ_NIP_FI_RESOLVER_*` and `BUZZ_NIP_FI_SNAPSHOT_*` are validated in every mode, so a bad value fails the deploy that sets it. In `off` mode no resolver is built and no snapshot is loaded. **Resolver (`nip_fi_resolver.rs`).** - **Snapshot:** each pod loads every binding into memory, capped at `BUZZ_NIP_FI_SNAPSHOT_MAX_ROWS` (going over is a failed load). It refreshes every 30 s, start to start, with jitter that only shortens the delay and backoff after failures. Each attempt is limited by `BUZZ_NIP_FI_SNAPSHOT_REFRESH_TIMEOUT_MS`, which must be shorter than the interval. A refresh whose deadline passes before it publishes publishes nothing. The old snapshot is dropped off the runtime. - **Freshness:** a host in a snapshot loaded under two minutes ago is answered from memory. Any other host, and every host once the snapshot is stale, goes to a live lookup. Every answer carries a deadline two minutes after the read behind it started, and WS, HTTP and audio recheck it just before admitting. - **Live lookups:** bounded and single-flight. In-flight lookups are capped by `BUZZ_NIP_FI_RESOLVER_MAX_INFLIGHT` (default 8, clamped below the database pool size), and the pending hosts and their waiters have fixed caps. Positive answers are used for that admission only. A "not found" is cached for 5 s, up to `BUZZ_NIP_FI_RESOLVER_NEGATIVE_CACHE_MAX` hosts, and only when no snapshot was published and no binding was created while it ran. A lookup that panics still leaves the pending map. - **Removal:** a removed binding stops admitting new connections within 30 s plus the refresh timeout (40 s by default) while refreshes succeed, and within two minutes of the last good load while they fail. Open WebSocket sessions are not rechecked when a binding is removed; they end at their own session deadline. **Shadow mode** resolves through the same path as enforce, including the database lookup and the freshness rules. It keeps the resolved binding's deadline and checks it at the same point as enforce; a binding that goes stale during the tenant lookup is recorded as `stage=deadline, outcome=unavailable`, without changing the legacy response or closing the socket. With `source=database` its `community` metric label is only `bound` or `unmapped`; with `source=env` it keeps the existing per-community audience label, so current shadow dashboards are unchanged. Each request resolves its Host once: the router guard's resolution, failures included, is reused by shadow recording and admission. **Provisioning.** Both operator provisioning paths drop this pod's cached "not found" for the new host after a commit that bound issuers, so the creator's first login looks it up. **Startup and readiness.** With `source=database` and a mode other than `off`, the first snapshot loads before any listener binds, under its own startup phase `nip_fi_snapshot_load`. A failed load exits non-zero, so a pod is never ready without a snapshot. **Operational consequence:** boot already fails when the database is unreachable; what is new is that a snapshot over `BUZZ_NIP_FI_SNAPSHOT_MAX_ROWS` or a load past its timeout also crash-loops new pods. After two minutes the old pods' snapshots go stale and most logins fall through to the 8-slot live lookup, which sheds the rest with 503. The way out is raising the cap or timeout, or `mode=off`. **Metrics.** `buzz_nip_fi_binding_snapshot_*` covers loads, failures, rows and freshness. `buzz_nip_fi_binding_snapshot_loaded_timestamp_seconds` is written on every refresh attempt, so alert on `time() - x > 120` together with `absent(x)`. `buzz_nip_fi_binding_snapshot_rows` against `buzz_nip_fi_binding_snapshot_max_rows` gives the headroom to the row cap. `buzz_nip_fi_resolver_*` covers live lookups and the negative cache. The env vars and alerts are documented in `.env.example`, the chart README and `docs/operator-nip-fi-bindings.md`, which also has the staged off → shadow → enforce rollout for `source=database` with go/no-go signals at each step, and the over-cap and load-timeout failure modes with their ways out. **Regression coverage.** Router-level tests run the database resolver through the real `build_router` for root WS, audio and protected HTTP, in enforce and shadow mode. Over PostgreSQL and Redis, two pods using the env community source (two exact bindings) replay assertions retained from before a disconnect through a real root NIP-42 session, the audio deny-set check and signed NIP-98 requests: they are denied on both pods, and a root session upgraded before the disconnect is refused by the post-registration deny-set check. Postgres tests in `buzz-db` check that archived and quiescing communities, and issuers missing from the registry, never reach the snapshot or the live lookup. Process-level `boot_lifecycle` tests spawn the real relay with `source=database`: an over-cap or timed-out startup load exits non-zero with no health listener bound, and a loadable snapshot lets readiness turn ready. --------- Signed-off-by: Will Pfleger <pfleger.will@gmail.com> Co-authored-by: Hayt <211b96e6a2b7f45fd4047988976c7bbbeeda0c15f3ae7b32eec20834b5a55118@buzz.block.builderlab.xyz> Co-authored-by: Duncan <dcfd242e557282d7a1e2cf2e6877522682f1e5c6156dc92ca7d90eaedd3b0f95@buzz.block.builderlab.xyz>	2026-10-19 10:32:18 -04:00

Tom Brow	5397ea49e2	fix(push): verify extended App Attest proofs with a focused owned module (#8329) ... ## Summary Apple SDK 27.1 device captures include authenticator extension data that the current verifier rejects. Replace the general appattest dependency with a private gateway module that verifies the complete original bytes, frames enrollment and assertions separately, and accepts well-formed optional extensions without SDK-specific length or flag allowlists. The module retains established signature, P-256, CBOR, and certificate-chain libraries. App identity, exact enrollment environment, credential/key binding, nonce, challenge, and increasing-counter checks remain enforced. Bounded parsing rejects ambiguous duplicate keys, truncation, trailing data, and oversized inputs. Fixture helpers are test-only. Adapted code retains both upstream MIT notices and source provenance. Category/version properties remain authenticated observations under the chosen compatibility-release policy. This does not implement Apple's additional distribution-category/version enforcement; introducing those restrictions requires a separately defined deployment policy. The [verification contract](https://github.com/block/buzz/blob/app-attest-owned-verifier/docs/app-attest-compatibility.md) records this and other limits. Related: https://github.com/block/buzz/pull/8020 addresses assertion extension handling. This change also covers enrollment extensions, credential-key parsing, and certificate validation. ### Validation - Gateway suites: 77 default tests and 79 personal-development tests passed, plus startup policy and Clippy. - Added signed enrollment/certificate, generated CBOR mutation, maximum-counter, and PostgreSQL race/replay coverage. All 12 isolated Postgres tests passed. Apple's historical fixture is tested structurally, not accepted as a current enrollment. Positive synthetic leaf certificates are generated at test time. - Protected SDK 26.5/27.1 enrollments and assertions pass the verifier, including the same key across SDK upgrades; development enrollment rejects under production policy. Captures are personal-development identities, not supported production-identity evidence. - Full local CI passed Rust tests and reached 6,828 passing desktop JS tests before an unchanged 10 ms focus-timer test failed; its five-test file passed in isolation. The pre-push native suite had 3,421 passes and an unchanged 300 ms child-PID test failure, also passing in isolation. Prior ACP timing flakes and these unrelated hook exceptions do not waive required CI. - Windows CI exposed a missing system OpenSSL installation for the test fixture generator. The test dependency now builds bundled OpenSSL; all 30 focused App Attest tests pass locally. [Current-head CI](https://github.com/block/buzz/actions/runs/38636062347) passed, including Windows Rust, PostgreSQL, and desktop integration tests. - [Prior-head Codex review](https://github.com/block/buzz/pull/8329#issuecomment-6177515598) found no major issues. Carl subsequently identified a dropped credential-length workaround; fixed in [27f9f26](27f9f2624f), with 34 focused/protected tests and Clippy passing. [Current-head Codex review](https://github.com/block/buzz/pull/8329#issuecomment-6178361143) found no major issues; physical iOS 26 testing was explicitly waived by Tom on October 14, 2026. No iOS 26 device test was performed. The SDK comparison used the same iOS 27.0.1 device, so it demonstrates SDK-linked variation without establishing OS-version causation. - Isolated candidate HTTP/device validation passed with separate authority state and no APNs delivery: SDK 26.5 enrollment/delegation, SDK 27.1 delegation with the exact same key and installation, and fresh SDK 27.1 enrollment/delegation. Assertions changed from 37 to 102 bytes across the upgrade; accepted counter increased from 1 to 3 and delegation generation from 1 to 2. All three runs rejected tampering and replay (401) and consumed challenges (404). Existing Buzz app builds were preserved. No production rollout is included. - Existing-installation validation passed against the current-head Dev gateway: a guarded SDK 27.1 diagnostic reused the stored key and installation, advanced the assertion counter from 88 to 89 and delegation from 89 to 90, and published the existing active relay lease at generation 9 (previously 8). Independent database reads confirmed the changes and preserved key, epoch, and expiry. The original app build was restored in place with current data and keys intact. --------- Signed-off-by: Tom Brow <tomb@block.xyz>	2026-10-15 07:15:19 -07:00
Logan Johnson	67c4fe5e17	fix(deps): bump rustls to 0.23.46 for RUSTSEC-2026-0346 and -0347 (#8319) ... 🤖 ## Summary The required Security check now fails on every branch, including main. The dependency audit (`cargo-deny`) reports two new advisories for rustls 0.23.45, the TLS library behind the relay, CLI and desktop connections: - **RUSTSEC-2026-0346:** printing a TLS client session value with `Debug` (for example, in a log line) shows its TLS secret. - **RUSTSEC-2026-0347:** when a server rejects Encrypted Client Hello (ECH, which hides the server name a client asks for), data the client buffered can go to the outer server. rustls 0.23.46 fixes both. This PR moves the root and desktop lockfiles to it, so the Security check passes again. ### Related issue None found. #8277 fixed an earlier advisory in the same way. ### Testing - `cargo-deny check` passes: "advisories ok, bans ok, licenses ok, sources ok". - `cargo tree --locked` resolves both lockfiles without more changes. Only the rustls version and checksum change. A plain `cargo update -p rustls` also moved unrelated `syn` and `getrandom` edges, so this PR leaves those out.

Luke Tornquist	d25384a4f3	buzz-db: admit every fenced-table writer in app code (#8219) ... ## Summary This makes every serving writer of a community-write-fenced table take community admission in application code. That's the "Dual enforcement" step of the Supported Writer Contract in `ARCHITECTURE.md`. Admission means the shared community deletion lock plus the active/not-deleted check from `deletion::guard_community_write`. It's taken before the transaction's first tenant write or row lock and held until commit. The 32 `community_write_fence_*` triggers, the six fence SQL functions and `validate_serving_catalog` are unchanged. They stay authoritative. Removing them is a separate migration that will be checked table by table. ## Changes - **New admission entry point.** `begin_community_write_transaction` (`runtime/mod.rs`) builds an `AdmittedTx` for non-event writers. It sits next to the existing event-write entry points and shares their implementation. - **Writers moved onto it:** - `api_tokens`, `archived_identities`, `channels`, `channel_members` (including DM and admin paths), `community_bans`, `git_repo_names` - `moderation_actions` and `moderation_reports`, `personal_read_accounts` and `personal_read_frontiers`, `pubkey_allowlist` - `push_leases`, `push_match_queue`, `push_wake_outbox` - `relay_invites`, `relay_members` (including the new-community owner bootstrap and the startup `pubkey_allowlist` backfill), `join_policy_acceptances` - `thread_metadata`, `users`, `workflows`, `workflow_runs`, `workflow_approvals`, `scheduled_workflow_fires` - Personal-read helpers now require `&mut AdmittedTx`. - **`buzz-audit`.** An append now passes admission first, then takes a transaction-scoped audit-chain lock (`pg_advisory_xact_lock`). This replaces the session lock and the `catch_unwind` unlock cleanup. The relay audit worker retries a `lock_timeout` on either lock and keeps the entry; an admission refusal is terminal, as the trigger's refusal was. - **Fleet-wide statements.** These keep `community_write_allowed(...)` in the same SQL statement, because there's no single community to admit up front: - scheduled-fire prune - invite expiry - push matcher claim and exhausted-job cleanup - startup `d_tag` backfill - channel TTL cleanup - **Relay-member removal.** `remove_relay_member` and `remove_relay_member_if_role` run `delete_member_with_acceptances` inside their admitted transaction. The helper no longer opens its own transaction, so the member lock, the `join_policy_acceptances` delete and the member delete all hold admission until commit. `delete_workflow` and `delete_workflow_for_owner` are gone on `main`, and the coordinate deletion path they used to back was already admitted. - **Unchanged exceptions.** The deletion-executor generation exception and the serving-lease path work as before. - **Tables with no production writer.** `delivery_log` and `subscriptions` are only written by a historical cutover script and a test fixture. Their triggers stay. - **No cross-community moves.** No production `community_id` move exists on a fenced table. The only `SET community_id = NULL` is the deletion-executor purge. So no dual-community lock ordering was needed. ## What got simpler - Per-store ad-hoc writer helpers are gone: `begin_event_write_transaction` and `acquire_event_write_connection` in `channel.rs`, and `begin_operation_transaction` in `push.rs`. - Audit append drops the session advisory unlock, the `catch_unwind`/`resume_unwind` panic handling, `log_inner` and the `futures-util` dependency. ## Notes for reviewers - **New crate dependency.** `buzz-audit` now depends on `buzz-db` only to call the free function `buzz_db::deletion::guard_community_write`. `ARCHITECTURE.md` names this as the one sanctioned subsystem edge, and its audit section is updated to match. - **Hot paths.** `ensure_user` first checks whether the user exists and returns without admission when it does (no write happens). Only a real insert takes admission. `touch_api_token` has no production caller today. - **No-op writers stay read-only.** The startup allowlist backfill returns early on plain reads when the legacy table is gone, it has no rows for the community, or the community already has members, so a quiescing deployment community still starts. It re-checks under admission before inserting. - **Owner mutations.** When admission refuses a transfer or a provisioning and a deletion request exists, both report `DeletionPending`, as before. For a transfer, the operator API keeps its coded `deletion_lifecycle_conflict` 409. For provisioning, it keeps the existing uncoded 409, `owner_conflict: community deletion is pending`. - **Per-community worker loops.** `claim_due_push_wakes` and similar now return `AccessDenied` for a community that goes quiescing between the active-host scan and the claim. The worker logs it at `debug` and the next scan skips the community. - **Kick side effects.** `membership_removal_fence` admits before the membership lock to keep the lock order of `add_member`. A community that leaves `active` between the kick and the fence skips live subscription eviction; the membership cache is already invalidated and fan-out re-checks membership. This is documented on the function. ## Testing - **New refusal tests.** 19 tests: the 18 in `store::admission_postgres_tests`, plus `audit_append_requires_application_admission_with_triggers_bypassed`. Each runs with ordinary triggers disabled (`session_replication_role = replica`), checks that a raw fenced insert would succeed, and asserts that the writer is refused for both `quiescing` and `fenced` communities. Active writes still succeed. - **The tests catch a missing check.** Measured in review at `6fc073c3f`: with the guard in `AdmittedTx::admit` bypassed, 25 tests fail. That includes 16 of the 18 database admission tests. The audit test stays green there, because audit calls `guard_community_write` directly. - **Affected PG suites, with triggers on:** 183/183 passed across 16 store suites, push 18/18 run isolated, audit 7/7. The existing artifact, reaction and replaceable admission tests pass. - **Review fixes, each checked to fail without its fix:** - `allowlist_backfill_requires_application_admission` and `owner_mutations_report_pending_deletion_when_admission_refuses` fail with the old `relay_members.rs`. - `empty_allowlist_backfill_skips_admission` fails (`AccessDenied … write-fenced (quiescing)`) without the allowlist-rows early return. - `audit_worker_retries_admission_lock_timeout_until_original_entry_is_appended_once` holds the community deletion lock exclusive and fails without the admission retry arm. - The existing audit-chain retry test now looks for the transaction-scoped lock and passes. - The two owner-revoke mini-schema tests (`bridge.rs`, `ingest.rs`) now include `communities` and `community_deletion_lock_key`, which admission reads; both failed without that. - **Static checks:** `cargo fmt --check` and workspace `cargo clippy --all-targets -D warnings` pass. - **Not run locally:** the `mobile-check` step of `just ci` (the build machine couldn't reach pub.dev, and clean base fails the same way) and the full `just test` lane. CI on this PR covers both. `mesh_demo::demo_join_forwarded_arm_round_trips_echo` fails on the build machine at base `394d4a434` as well; it uses no database.

klopez4212	5dc693aeaf	Extract shared Huddle audio client for desktop consumers (#8129) ... Huddle audio was embedded in the v0 desktop client, forcing other clients to duplicate its protocol and codec behavior. This extracts `buzz-audio-client` so v1 can depend on a pinned library revision without building the v0 application. The crate owns the bounded v2 audio handshake, roster parsing, wire format, Opus sender, and per-peer NetEQ jitter buffer. The v0 human and agent senders use it, and the desktop retains room admission, identity/signing, TLS policy, device routing, mute, and teardown. Receive decoding preserves v1's support for 120 ms Opus packets. No relay protocol changes, speech models, or model downloads are included. Docker builder stages include CMake because cargo-chef compiles the workspace dependency graph. Dependency security: Opus 0.4 replaces the unmaintained `audiopus_sys` backend with `opusic-sys`. NetEQ is pinned exactly to 0.8.3 because its published Rust sources never reference its declared ringbuf dependency. RUSTSEC-2026-0293 is documented as unreachable for this audited source, and a wrapper restriction rejects every other consumer of vulnerable ringbuf versions. Independent review confirmed the scope; re-audit/remove the exception when changing NetEQ. NetEQ 0.9.1 still declares ringbuf 0.3, so a version bump alone does not remove it. Local `cargo deny check` passes with this constrained exception. Validation: - All 21 shared-crate tests pass, including real loopback WebSocket authentication/cancellation, real Opus-to-NetEQ playback, malformed input, and 120 ms decoding. These tests are included in `just test-unit`. - Shared-crate, root workspace, and desktop Tauri Clippy pass; `just desktop-tauri-check` passes. - The desktop Tauri test workspace passes; native two-person listening/device checks remain separate. - All mandatory push checks pass at `d06bac5dc`, including the complete Rust unit gate and desktop workspace checks. Existing agent timing and relay log-capture tests failed under concurrent load, passed separately, and passed in the full serial test run; no tests or hooks were skipped. - One test-only fixture change allows cold Perl startup before the escaped-process test's inner timeout (2 seconds instead of 300 ms). Its independent 5-second watchdog, 300-second surviving pipe writer, and all assertions remain intact. All eight process-helper tests pass; independent review confirmed this still tests bounded drain completion. - Dependency inspection confirms the library brings in no desktop application, Tauri, identity store, relay server, or speech-model crates. - Independent source review found no correctness blockers. Draft: a native two-person call, mute/leave/cancellation, and microphone/speaker switching still need a runtime tryout and human review. Full `just ci` was stopped during the unrelated mobile toolchain download because of disk pressure; it is not a passing gate. Consumer integration is tracked in block/buzz-app#489. --------- Signed-off-by: kenny lopez <klopez4212@gmail.com>	2026-10-13 16:24:27 -04:00
Tom Brow	5b907b838a	fix(push): isolate push enqueue and stop workers on rollback (#8216) ... Push enqueueing previously ran inside the message transaction, so a push lock or database error could block or reject a message. Configured relay writers now submit bounded best-effort work only after commit. A dedicated connection and bounded queue isolate enqueue waits and failures from message-write connections. Overload, errors, process loss, or shutdown may drop a notification; the committed message remains authoritative. `BUZZ_PUSH_ENABLED=false` disables the application producer and workers. Updated writer connections always bypass any surviving enqueue trigger. The overlap migration updates an existing function without resurrecting retired objects. Apply it before relying on isolation with a surviving trigger, and replace every old enabled process and writer connection: missing settings preserve legacy behavior during overlap. SIGTERM/Ctrl-C cancels enqueue, matcher, and delivery work before listener drain. Durable queues, claims, leases, preferences, and delivery configuration remain intact. Claims expire normally; gateway requests already accepted may still deliver. Reactivation requires an explicit operator decision about retained work. There is no automatic purge, startup interlock, or backfill of messages written while disabled. Built on merged [#8135](https://github.com/block/buzz/pull/8135), including [#8178](https://github.com/block/buzz/pull/8178). Trigger retirement [#8210](https://github.com/block/buzz/pull/8210) remains open; this change is tested with the trigger present and after removal. Operational details are in [the rollback and reactivation guide](https://github.com/block/buzz/blob/relay-push-rollback/docs/push-gateway-deployment.md#relay-rollback-and-reactivation). ### Validation [9d3d710](9d3d710dc1) changes documentation and Rust comments only, with no executable or assertion changes. Formatting and diff checks passed; [12f1d1e](12f1d1e814) additionally restores the reviewer-requested caveat that active lease renewal may suppress a notification. This is also documentation-only; Owner approval was confirmed on 12f1d1e. [a4f602d](a4f602df49) subsequently merges main to resolve a migration-count conflict after main added migration 0058. Both 0058 and rollback migration 0059 are retained; the focused embedded-migrator test, formatting, and applicable desktop pre-push checks passed. Current-head [owner approval](https://github.com/block/buzz/pull/8216#pullrequestreview-5474958334) is confirmed. [CI attempt 2 passed](https://github.com/block/buzz/actions/runs/37985516452/attempts/2), with required checks passing or appropriately skipped. The first attempt failed only the unchanged replica-floor probe test with `MaskedActivity { masked: 1 }`; one failed-jobs retry passed without code changes. All four push contract tests passed. The current-head [advisory security review](https://github.com/block/buzz/actions/runs/37985514346/job/114006457769) has remained in its review step since 20:18:51 UTC without a published result for over 25 minutes. It is stalled under the advisory-review policy, not a clean security review. [Required CI checks passed or were skipped](https://github.com/block/buzz/actions/runs/37964035783) on [3164b25](3164b25cde). The advisory security review was cancelled without a published result. Codex's durable-retry suggestion was [rebutted and resolved](https://github.com/block/buzz/pull/8216#discussion_r4232674980) under the explicit best-effort notification contract. The [lease activation-order observation](https://github.com/block/buzz/pull/8216#discussion_r4233051799) is correct. Under the clarified product requirement, either notification outcome is acceptable during overlapping registration and message arrival. Exact commit ordering is not required; deliberate historical backfill remains prohibited. The bot thread is resolved against that clarification; [Owner review accepted the clarified overlap contract](https://github.com/block/buzz/pull/8216#pullrequestreview-5474720278) on 9d3d710. All 488 PostgreSQL tests passed. The final four-way producer contracts passed on desired/migrated schemas, with/without triggers. Added coverage verifies message commit under push-gate and queue-table locks, recovery after enqueue failure, in-flight enqueue cancellation, the lease timestamp filter (not production activation ordering), serving-lease writers, rollback preservation, reconnects, and reactivation without backfill. Queue saturation and all three relay worker shutdown tests passed. Rust lint and all 17 source-policy checks passed. Full local CI/repository runs encountered the unchanged ACP `keepalive_resets_idle_past_deadline` timing failure. Earlier desktop subprocess timing tests also failed under parallel load and passed as an isolated module. Under Tom's local pre-push exception, this update excluded `rust-tests` and `desktop-tauri-checks`; remaining hooks stayed enabled. Required CI validation remains necessary before merge. A focused run competing with the full database suite hit wall-clock deadlines; tests now use a short database lock timeout to distinguish unwanted push dependencies, and their final isolated run passed. A local process-replacement rehearsal on 3164b25 used the real relay binary and a mock gateway holding a delivery request open. SIGTERM closed that request in under 1 ms; the relay exited in 5.02 seconds. Restarting the same binary with push disabled produced no further gateway requests over 35 seconds, beyond the 30-second claim expiry. The outbox row, lease, and its subscriptions remained byte-for-byte unchanged. This used a seeded outbox and did not exercise APNs or a mobile device. Production writer inventory, shutdown deadline, and retained-queue disposition still require operational validation before rollout. The PR is marked ready for review. The overlap behavior is accepted by the product requirement; owner review accepted that contract.

Bartok	b9e851d7be	fix(buzz-pair): install rustls ring CryptoProvider before WSS (#7998) ... ## Summary - `buzz-pair` panics on any `wss://` relay (including the documented default `wss://relay.damus.io`) because no rustls `CryptoProvider` is installed. `ws://` is unaffected. - Sibling binaries already install ring explicitly (`crates/buzz-cli/src/lib.rs`) and take a direct `rustls` dep with the `ring` feature so a unified release build can still select a provider. - This applies the same two-line pattern to `buzz-pairing-cli`: direct `rustls` dep (`ring` + `std`) and `install_default()` at the top of `main()`, before any connection. Fixes #7927. ## Test plan - [x] Diff matches the established `buzz-cli` install pattern (same dep features, same `let _ =` swallow on double-install). - [x] `cargo build -p buzz-pairing-cli` and `buzz-pair source --relay wss://relay.damus.io` reaches "Waiting for target" without the rustls panic. - [x] `buzz-pair test-vectors` still exits 0 (no WSS, install is a no-op). --------- Signed-off-by: Bartok9 <259807879+Bartok9@users.noreply.github.com>	2026-10-06 14:50:21 -07:00

klopez4212	5173fad660	feat(pairing): enter desktop codes on mobile (#8085) ... ## Summary Enter a desktop-only, random six-digit code on mobile to pair without a desktop confirmation click. Verification uses the encrypted session, limits guesses to five, and never treats the QR-derived transcript as approval. Older clients retain desktop confirmation. Adds digit-only error shakes and native haptics, a separate biometrics choice, and a direct community-icon arrival animation. Fixes dropped early offers and resets completed pairing so reopening or signing out cannot get stuck. ### Related issue Related: #8060; no duplicate code-entry PR found. <img width="780" height="1688" alt="01-enter-code" src="https://github.com/user-attachments/assets/a99ced3e-4305-4ac6-a6cc-d598ced423e7" /> <img width="780" height="1688" alt="02-incorrect-code" src="https://github.com/user-attachments/assets/19cdb109-1f10-40a9-a661-1d7ba89c81c1" /> <img width="780" height="1688" alt="03-biometrics" src="https://github.com/user-attachments/assets/af1b2924-9ab6-4d1a-b4b1-fccfdf446404" /> <img width="780" height="1688" alt="04-community-loading" src="https://github.com/user-attachments/assets/84145d82-843a-4c25-aef7-6492fc241d4b" /> <img width="897" height="388" alt="05-desktop-code" src="https://github.com/user-attachments/assets/d8a2e469-7e42-466a-988f-bab6b1df85fc" /> ### Release order Deploy the updated pairing relay first, then desktop, then mobile. The relay now allows eight events per connection (seven for a successful fifth guess plus room for cancellation), with a corresponding bounded delivery budget. Existing clients remain supported; older client combinations keep desktop confirmation. ### Testing - 103 mobile pairing tests, 270 core tests, 51 relay integration tests, and the new real-relay fifth-guess flow passed. - The real-relay regression verifies proof, decrypted identity import, and completion after four wrong guesses. Restoring the old six-event cap makes it fail. - A paused-clock desktop regression confirms slow readiness cannot extend the visible QR beyond protocol expiry. Mobile regression covers typing before negotiation completes. - Core/pair-relay Clippy and full native desktop Clippy/workspace tests passed. Mobile analysis passed; broad mobile runs each hit an unrelated failure (a gateway-script timeout and a native-menu missing-plugin error), and both affected test files passed separately. - Repository-wide Rust testing exhausted local disk space while compiling unrelated packages. The final push omitted that resource-blocked hook and avoided repeating the desktop/mobile runs above; hosted CI remains required. --------- Signed-off-by: kenny lopez <klopez4212@gmail.com>	2026-10-05 13:42:39 -04:00
Alex Rosenzweig	4f51b9e101	fix(mcp): support Goose discovery handshake (#8037) ... ## Summary Goose 1.52 starts MCP connections with `server/discover`. `buzz-dev-mcp` rejects that request with `ExpectedInitializeRequest`, preventing Goose from loading its Buzz tools. Upgrade the tool server to rmcp 3.4.1 and adopt the renamed SDK types. Subprocess tests exercise discovery and legacy initialization, tool listing, file reads/edits, invalid arguments, connection survival, and EOF shutdown. Include the server in both Rust unit-test runners and make the cancellation regression approve its shell call before testing cancellation. The native agent retains its independent rmcp 1.x client. Cargo also unifies the existing 3.x dependency used by the mesh smoke harness. ## Validation - Normal `git push` passed all hooks, including Rust tests, Tauri checks, and repository policy checks. - `just ci` passed on the final stack: repository checks, Rust and Tauri tests/lint, desktop tests/build, web build, and mobile checks/tests. - MCP: 78 existing tests and two subprocess lifecycle tests passed; the discovery regression fails with the old SDK. - All 54 native-agent regressions passed on the final stack, including cancellation of a real MCP shell process. - Previously exercised unmodified Goose 1.52 and 1.47 with Sandpit and the real tool server. Allowed workspace operations and permitted network traffic succeeded; disallowed file and network operations were denied. - Live staging desktop check with Goose 1.52: the reply appeared in Buzz, an allowed request returned HTTP 200, and a disallowed request returned CONNECT 403. ## Stack 1. **#8042 → `main`**: deterministic handoff regression. 2. **This PR → #8042**: Goose MCP discovery compatibility. Merge the lower PR first, then retarget this PR to `main`. This diff contains only the compatibility change and its tests; the relay build repair is already on `main` in #8036. --------- Signed-off-by: Alex Rosenzweig <arosenzweig@squareup.com>	2026-10-02 11:24:25 -05:00
Will Pfleger	16839a0773	feat(nip-fi): admin disconnect/deny API with in-memory deny-until-TTL map (S4) (#7977) ... This adds the NIP-FI S4 admin command surface. An authorized issuer principal can deny an `(issuer, pubkey)` pair until a TTL expires. When that happens, the relay records the entry in a bounded in-memory deny map, closes matching live sockets on every pod, and refuses new admissions while the entry is live. Supersedes #7265 ## Breaking In `BUZZ_NIP_FI_MODE=enforce`, every entry in `BUZZ_NIP_FI_ISSUERS` now has to carry `maximum_command_age_seconds` (1–60) and a non-empty `authorized_principals` list, and startup fails if any issuer is missing either one. That means an S3-only enforce config that boots on `main` won't boot with this change. No deployment sets `BUZZ_NIP_FI_*` yet. The per-issuer field table and a working example are in the `nip_fi_config.rs` module docs. ## What changes - **`buzz-auth`**: - `nip_fi/command.rs` verifies signed admin commands. It checks issuer policy, command age, the authorized principal (exact, case-sensitive `sub` match), and a `jti` of at most 512 bytes. - `nip_fi/deny_map.rs` is a per-issuer, capacity-bounded deny-until-TTL map on top of `DashMap`. Expired entries and `jti` reservations are only swept when a write would otherwise hit capacity. The sweep is O(n) and holds the lock every admission check takes, so this keeps it off the admission path. Reads compare against `now`, so an expired entry that hasn't been swept yet never counts as live. - **Cross-pod command replay fence**: `nip_fi/command_replay.rs` adds a `CommandReplayGuard` trait, and `buzz-pubsub` implements it in Redis (`RedisCommandReplayGuard`), following the NIP-98 replay guard. Once a command is authenticated, the verifier takes an atomic `SET buzz:nip-fi:command:{sha256(len(iss)‖iss‖len(jti)‖jti)} 1 NX EX <ttl>` claim, with the TTL set to the command's remaining validity rounded up to whole seconds plus skew, clamped like NIP-98, so the claim outlives acceptance by a verifier whose clock trails by the full skew. Before the claim, the verifier reserves a pending `jti` and deny-entry slot in this pod's deny map under the issuer lock, so a full deny set returns `503 deny set full` without touching Redis and the same signed command can be retried. The claim is taken only after the signature and claims verify, so a forged token cannot burn a real `jti`. A `jti` already claimed on any pod returns `403`. A Redis error fails closed with `503 authorization unavailable`: no deny entry, no session close, no publish. A replayed claim, a Redis error, or a cancelled request drops the reservation. After a successful claim the reservation commits to the `jti` record and deny entry, which cannot fail on capacity. A claim can still remain with no deny entry if Redis applied `SET` but the reply was lost, or the pod stops between claim and commit; that fails closed, and a retry gets `403` until the TTL expires. - **`api/nip_fi.rs`**: the admin disconnect/deny endpoint. It verifies the command, inserts the deny entry, disconnects locally, and publishes over `buzz-pubsub` `conn_control` so every other pod runs the same disconnect. A receiving pod clamps `until` to its own ceiling instead of rejecting it. Otherwise a pod whose clock trails the origin would drop a command the origin already answered with 200, and the target's sockets on that pod would stay open. Malformed pubkeys, unknown issuers, and unrepresentable timestamps are still rejected. - **Admission and live enforcement**: - WS upgrade (`router.rs`) and HTTP (`nip_fi_http.rs`) refuse keys that have a live entry with `403 authorization_denied`. - Root NIP-42 auth and audio auth register the proven identity (pubkey + admitting issuer) first, and only then check the deny map. With that order, a concurrent disconnect either finds the socket in its close scan or the check finds the entry. `OK(true)` isn't sent if a concurrent disconnect already cancelled the session. - `ConnectionManager::disconnect_nip_fi` and `CommunityConnectionRegistry::disconnect_nip_fi` are scoped to the issuer. - **One wire form for `authorization_denied`** (FI-TRACE-DENIAL-ORACLE): every root and audio WebSocket `authorization_denied` denial now goes through one first-writer-wins transition on `CommunityConnectionControl`. That covers the S4 deny-set hit and admin disconnect, and also the existing S3 key-mismatch, lease-expiry, and membership refusals. The transition sets the `AuthorizationDenied` reason only if nothing else has set a reason, and only the winner enqueues the denial frame. So every one of these denials is the class's denial frame followed by `Close(1008, "authorization denied")`, and a concurrent registry scan can't queue a second one. Before this, S3 key mismatch and expiry closed with `Close(None)`, which made them distinguishable from a deny-set hit on the wire. `evidence_rejected` and `authorization_unavailable` keep the bare close. - **Config**: see Breaking. `deny_set_capacity` is optional and defaults to 50000. Setting any command field without a command age fails closed. - **Boot** (`main.rs`): installs the command verifier and deny map. It subscribes to cross-pod disconnects before the Redis subscriber starts, so disconnects relayed during boot are buffered instead of dropped. --------- Signed-off-by: Will Pfleger <pfleger.will@gmail.com> Signed-off-by: Will Pfleger <wpfleger@block.xyz> Co-authored-by: Duncan <dcfd242e557282d7a1e2cf2e6877522682f1e5c6156dc92ca7d90eaedd3b0f95@buzz.block.builderlab.xyz> Co-authored-by: Hayt <211b96e6a2b7f45fd4047988976c7bbbeeda0c15f3ae7b32eec20834b5a55118@buzz.block.builderlab.xyz>	2026-10-01 19:40:09 +00:00
Ian Oberst	14a752fb24	fix(db): audit partition catalog before creation (#6515) ... ## Why The partition manager checks partition existence by name only and treats Postgres 42P17 "would overlap partition" errors as success. On databases where a catch-all partition (`events_p_future` / `delivery_log_p_future`) covers future months, the monthly creation path silently does nothing while real coverage erodes toward a write outage. There is currently no visibility into partition catalog health and no signal before writes start failing. ## What - **Read-only catalog audit** in `buzz-db` (`partition.rs`): classifies the live partition catalog for `events` and `delivery_log` via `pg_inherits` and bound parsing — coverage bounds, catch-all detection, anomalous children, and trigger parity checked recursively down to routable leaf partitions. - **Creation gated on the audit verdict**: the 42P17-to-success swallow is removed; monthly CREATE runs only for months the audit proves uncovered, a canonical-name mismatch is an error, and per-month outcome capture replaces first-error abort. New `BUZZ_PARTITION_MANAGER_CREATE_ENABLED` kill switch (default `true`). - **Prometheus metrics** per table: `buzz_partition_serving_safe`, `buzz_partition_uncovered_months` (audit window is now through +3 months), `buzz_partition_catch_all_covered_months`, `buzz_partition_anomalous_children`, `buzz_partition_trigger_parity_missing`/`_extra`, `buzz_partition_audit_duration_seconds`, `buzz_partition_audit_runs_total{outcome}`, `buzz_partition_audit_failures_total`, `buzz_partition_create_attempts_total`, and `buzz_partition_audit_last_success_timestamp_seconds` for staleness alerting. - **Cached diagnostics**: `/_status.partition_catalog` reports partition serving-safety, audit age, and freshness. `/_readiness` stays process-local, consistent with #7341; missing, unsafe, or stale audits do not remove pods from service. - **Periodic audit task** in the relay, plus config surface for the audit interval and the monthly-create kill switch. Catch-alls are detected from catalog bounds rather than configured names. - Doc correction: the mesh heartbeat comment no longer claims readiness gating (it never was gated; behavior unchanged). ## Behavior changes & risk - No DETACH/DROP/ATTACH and no schema migrations. The only DDL is the pre-existing monthly CREATE path, now strictly narrower (audit-proven-uncovered months only) and behind a kill switch. - Partition audit health does not gate readiness. Until the first completed audit, read-only retries back off from 5 seconds to a 60-second cap. Any completed audit, including unsafe coverage, restores the normal interval. - Partition-overlap errors now surface as errors instead of being swallowed as success. - Rollback: revert the commit, or set `BUZZ_PARTITION_MANAGER_CREATE_ENABLED=false` to disable the creation path while keeping the audit and metrics. ## Validation - New Postgres-backed regression tests for catalog classification and trigger parity (disabled child trigger, `ENABLE ALWAYS` parent, disabled nested leaf clone in a multi-level layout, healthy-catalog zero-parity checks). Each new regression was verified to fail against the previous logic before the fix. - Local affected-target validation passed against a disposable current-schema database, with the known mesh forwarded-echo and tracing callsite failures excluded. This is not a claim that the full suite passes. Follow-up work (separate PRs): bounded catch-all advance (empty-only golden path; non-empty reattach only behind an explicit operator flag, default off), fresh-install convergence, and proactive coverage-runway alerting. --- ## Update — 2026-08-21 - Fixed nested-leaf trigger parity auditing so child-only row triggers are checked on every routable descendant leaf and reported as `{leaf}:{trigger}` under the owning root child. - Added a Postgres regression test for a child-only trigger on a nested leaf; mutation-reverting to immediate-child-only extra-trigger scanning makes it fail.

Bradley Axen	12670bd0f0	feat(relay): implement NIP-AR channel artifacts (#7919) ... ## Summary Implements NIP-AR channel artifacts (spec merged in #7791) on the relay, after a simplicity pass over the earlier two-agent implementation. An artifact is an editable record (kind 45010) with a stable identity (`d`), one home channel (`h`), and full-snapshot revisions chained by `prev`: - **Writes:** one transaction per write. It locks the artifact's head row, requires `prev` to name the current revision, records the revision in a ledger that survives retention, and advances the head. Two competing edits can't both win. A stale edit gets `conflict: artifact head changed`. Resubmitting an accepted event succeeds without applying it twice. - **Permissions:** writes pass the same gates as a kind 9 message in `h`. A move also passes them in the source channel. The move stores the destination snapshot and a relay-signed kind 45011 removal marker for the source in the same transaction, so both channels recover by replay. The marker never names the destination. - **Moderation:** redaction is the ordinary kind 9005 removal. The ledger keeps the ID so `prev` checks still work. Redacting the current revision retires the artifact. - **Reads:** HTTP `/query` and `/count` accept explicit `artifact: current|history` filters with exact multi-character tag matching (e.g. `#assignee`). Generic REQ and search return only current revisions. Kind 5 against artifacts is rejected. NIP-11 advertises the limits. - **Spec:** NIP-AR updated to match: kind 9 permission checks, 9005 redaction and retirement, no creator-only delete rule. A separate small commit routes `insert_channel_head_checked` through the metered writer pool (`acquire_writer`), like every other event write in that module. ### Related issue Follows #7791. No separate issue found. ### Testing - Clippy clean. - Unit lane passes. Failures seen along the way came from agent env leaking into `buzz-acp` tests (they pass in a clean env) and known timing flakes (`keepalive_resets_idle_past_deadline`, two `buzz-agent` databricks tests that passed on retry). This diff doesn't touch those crates. - Postgres lane passes, including new `artifact_postgres_tests` in `buzz-db` and `buzz-relay`. Three presence tests need `REDIS_URL` set. - Docker smoke against a fresh local relay, 29/29: create and idempotent resubmit, update and stale conflict, current, `#assignee` and history queries, generic REQ, kind 5 rejection, delete and restore, move with source marker, private-channel isolation, and 9005 retirement. - A pasteable curl walkthrough of the same flows was shared with the reviewer. Draft until the human hands-on check (AGENTS.md step 3) is confirmed. The pre-push hook was skipped because every lane above had already run on this tree.

Will Pfleger	6410e685a8	feat(relay): enforce NIP-FI assertion+NIP-98 pairing on HTTP ingress (#7264) ... Implements NIP-FI HTTP ingress enforcement per the merged spec (PR #7254). Every protected HTTP surface in enforce mode requires a valid `Nostr-Federated-Identity: Bearer <JWS>` assertion alongside its NIP-98 authorization, bound to the same key. The NIP-98 pubkey (proven actor) must equal the assertion's `nostr_pubkey`; absent, mismatched, or unverifiable assertions are denied fail-closed with byte-exact text/plain responses per the spec's rejection table. This is S5 of the `buzz-enterprise-identity` program. WS enforcement (S3) is separate. ## What changed **New `nip_fi_http` module:** `admit_nip_fi_http()` covers the full admission sequence — `Nostr-Federated-Identity` extraction, offline JWKS verification, NIP-98 key pairing [FI-INV-05], issuer-qualified deny-map check via `(iss, pubkey, now)` [FI-INV-14], and byte-exact denial for all four `DenialClass` variants. `admit_nip_fi_http_on_state()` is the single call-site wrapper for all surfaces [FI-TRACE-AUTHORITY-UNIFORM]. **Protected surfaces** (all gated via the uniform authority): - HTTP bridge: `POST /events`, `/query`, `/count` - GIF proxy: `POST /gifs/search`, `/gifs/share` - Workflow reads: `GET /workflows/{id}/runs`, `GET /workflows/{id}/runs/{id}/approvals` - Moderation reads: `GET /moderation/reports`, `/moderation/audit`, `/moderation/restricted` - Media/Blossom: `PUT /upload`, `/media/upload` - Git smart-HTTP: `info/refs`, `upload-pack`, `receive-pack` - Git settings control plane: `GET`/`POST /git/:owner/:repo/default-branch` (now routed through `admit_nip_fi_http_on_state` for full assertion key-pairing) - Invites: `POST /api/invites` (mint only; claim exempt as pre-membership enrollment door) **NIP-98 strictness in NIP-FI mode:** - When NIP-FI is not Off, bridge POST handlers force `require_auth_token = true` — the `X-Pubkey` dev-mode fallback cannot satisfy the pairing requirement [NIP-FI.md:547-567] - POST bodies on `/events`, `/query`, `/count` require a matching `payload` tag in enforce mode [NIP-FI.md:579-597] - A payload tag present with no content (one-element `["payload"]` or empty string) is rejected as a structurally invalid claim — NIP-98 requires the content to be a valid 64-char lowercase hex SHA-256 digest. Malformed payload diagnostics use a static error message (no attacker-controlled content in logs). - Off mode preserves pre-NIP-FI behavior per [FI-INV-15] **Off-mode compatibility changes:** Admission now runs before request validation on every protected surface, so Off mode differs from pre-NIP-FI behavior in these ways: - **GIF routes:** NIP-98 authentication happens before the upstream provider lookup. An unauthenticated request on a tenant with no GIF provider now returns 401 instead of 404. The 401 goes through the legacy `api_error()` path, so the body is JSON `{"error":"..."}` with no `WWW-Authenticate` header. - **Workflow runs** (`GET /workflows/{id}/runs`): the query string is parsed after admission. A request with a missing credential and a malformed query (for example `?limit=abc`) now returns 401 instead of 400. - **Authorized malformed query:** once admitted, a malformed query returns a JSON 400 `{"error":"invalid query: ..."}` from `parse_query_or_400` instead of axum's `text/plain` `Query` rejection. - **Moderation reads** (`/moderation/reports`, `/moderation/audit`): same extraction change as workflow runs. Admission comes first, then a JSON 400 for a malformed query. - **Malformed `payload` tag:** shared NIP-98 verification now rejects a malformed `payload` tag in every mode, including on bodyless requests. That means a one-element `["payload"]`, an empty digest, or anything other than 64 lowercase hex characters. Before this change, a bodyless request ignored the tag. **Auth header cardinality:** Enforce mode rejects requests with more than one `Authorization` header with 403 `evidence rejected\n`. DenyProtected returns 503 `authorization unavailable\n` before this check (and before NIP-98 or assertion verification) runs. The cardinality gate is enforced at the NIP-FI admission boundary (`admit_nip_fi_http`), not via legacy auth boolean flags, so it applies uniformly to all Enforce-mode surfaces including Git. Off mode passes through the first header value unchanged, preserving pre-NIP-FI behavior [FI-INV-15]. **Denial-class remapping:** In Enforce mode, NIP-98 extraction/verification failures from the closure are mapped to the appropriate `DenialClass`: `MissingEvidence` when no `Authorization` header is present, `EvidenceRejected` when the header is present but invalid. Off mode propagates legacy responses unchanged [FI-INV-15]; for example, the Git missing-Authorization and wrong-scheme 401s keep their legacy bytes with no `content-type` header. **JWKS refresh scheduling:** The refresh timer's `*last` checkpoint is set after the fetch completes, not from the pre-fetch timestamp, preventing interval drift under network latency. The loop is extracted to `nip_fi_jwks_refresh_loop` for unit-testability. **Log hygiene [NIP-FI.md:777-779]:** Issuer identity is never written to logs or error messages. All startup/refresh diagnostics use an ordinal index (`issuer_index = N`). Config parse errors for malformed issuers use classify()/line/column codes rather than raw config values. **Admin SPA document routes:** `/reports`, `/reports/{id}`, and `/feedback` are exempt from the NIP-FI assertion guard only on the admin host (host-qualified via `is_admin_host`). These paths are not added to the broad `NIP_FI_EXEMPT_PREFIXES` list — tenant hosts remain fully protected. **Deny-map seam (`HttpDenyMap` trait):** signature is `(issuer, pubkey, now)` matching `NipFiDenyMap::is_denied` from S4 (PR #7265) so integration is a one-liner. Stub is `AlwaysAdmitStubDenyMap` — named to accurately describe stub-phase semantics (fail-open intentionally pending S4). **Route inventory:** every authenticated HTTP route is classified as Protected or Exempt with justification. Documented in the F4 seam-test comment in `bridge.rs`. **Outer-guard tests:** `#[ignore = "requires Postgres"]` tests in `bridge.rs` drive the full router (`build_router`) in Enforce mode with valid NIP-98 but no `Nostr-Federated-Identity` header. These exercise the **outer `nip_fi_assertion_guard` middleware** in `router.rs` — the layer that fires before any handler runs. They prove the guard's exact response bytes (401 `authentication required\n`, `text/plain; charset=utf-8`, `WWW-Authenticate: Nostr`) for each protected route. Per-handler `admit_nip_fi_http_on_state` wiring is proven separately by the cardinality test and the media/settings/git handler-level suites. ## Seams **S3 seam:** `nip_fi_config.rs` is duplicated (S3 not landed; session-deadline parts stripped). Removed when S5 rebases onto S3. **S4 seam:** `AlwaysAdmitStubDenyMap` until S4 provides the real map. Integration is one line at the `admit_nip_fi_http_on_state` wrapper. ## Evidence At head `ee338ea9c` (branch `hayt/nip-fi-http-enforcement`), hosted CI run [36167450853](https://github.com/block/buzz/actions/runs/36167450853): - **Rust / Unit Tests** ([job 108179338458](https://github.com/block/buzz/actions/runs/36167450853/job/108179338458)): passed.

Luke Tornquist	8f6b66f9ff	Select one feature flag provider at compile time (#7677) ... ## Why Buzz server components need one typed feature-flag contract without forcing the open-source build to depend on LaunchDarkly. A staging or production relay must not be able to choose the wrong provider through runtime configuration. ## What - Adds typed boolean and signed `i64` flags with static, environment, and compile-gated LaunchDarkly evaluators. - Defines an executable relay artifact contract that compiles exactly one provider. - Rejects zero or multiple relay provider features at compile time. - Runs the LaunchDarkly feature tests and the provider compile matrix in the unit CI lane and fallback test script. ## How `buzz-feature-flags` stays provider-neutral. The future relay composition root will expose one build path per artifact feature: `static-feature-flags`, `environment-feature-flags`, or `launchdarkly-feature-flags`. Runtime configuration carries only settings for the selected provider. It never carries a provider name, fallback, or precedence rule. The crate still has no relay consumer. A locked compile fixture proves each singleton builds and every zero or multi-provider combination fails until the relay adopts this contract. This removes the proposed runtime `ProviderMode` and leaves one provider, one construction path, and one evaluator per artifact. ## Risk This PR still has no relay or app consumer, so it changes no user-visible behavior. Risk is limited to the new feature-flag crate, its compile contract, and its unit-test lane. ## Testing An external Rust consumer at `30cf968bfe85e82980fda7e63f5bebe649ca939f` exercised six environment-evaluator scenarios and 59 assertions. The compile-time correction adds no live consumer to exercise manually. ## Bigger picture When `buzz-relay` adopts this crate, its build manifests must map each distribution to one provider feature. That consumer PR must verify live Relay Proxy reachability, secret ingestion, lifecycle ownership, and user-visible behavior.

Logan Johnson	ea1e97e65f	feat(acp): run one prepared task from a file or stdin (#7851) ... 🤖 ## Summary Scripts, scheduled jobs, and other automation need to give an agent one prepared task and wait for a result without starting a long-running chat listener. This adds `buzz-acp run`: it reads a task from a local file or stdin, runs one fresh agent session with the configured tools and instructions, cleans up, and exits with a machine-readable status. ```sh buzz-acp run --task ./task.json cat task.json | buzz-acp run --task - ``` - The versioned JSON task specifies a task ID, intended agent public key, prepared prompt, and execution time limit. Invalid input or an identity mismatch is rejected before agent launch. Credentials, executable, tools, and permissions remain controlled by trusted launch settings, not the task document. - Each invocation uses the normal agent equipment: base/persona/team instructions, enabled memory, tools, model and effort settings, permissions, and Git identity, credentials, and signing. Both task and conversational modes obtain these capabilities from one shared runtime owner; new shared setup belongs there rather than in separate entry points. - Launch configuration reads have a separate ten-second bound and can be cancelled even when a prompt file blocks. A deadline covers adapter startup through the task turn. Interrupts and termination signals trigger bounded cleanup. Stdout contains one terminal JSON record; diagnostics stay on stderr. A normal turn ending is not proof that the task achieved its goal. - Normal invocation remains the conversational service. Task mode does not start chat subscriptions, presence, heartbeat turns, or a persistent agent pool. Tasks are trusted executable instructions, not sandboxed input. Reusing a task ID does not prevent duplicate execution, and uncertain outcomes must not be blindly retried. See [the task contract](crates/buzz-acp/TASKS.md) for the document format, exit codes, limits, and examples. URL retrieval, a task server, and a persistent execution ledger are outside this change. ### Related issue None found in the existing issue and PR search. ### Testing - At `4e86bbc97`: 964 unit tests and 22 integration tests passed, with three existing ignored tests. The package suite ran serially with inherited harness/Git options cleared. A final test-only shutdown-result assertion was then checked with the focused memory test and all-target Clippy. - All eight real-binary task tests independently passed on the exact candidate, including blocked configuration reads, file/stdin validation, session equipment, deadlines, cancellation, and cleanup. The memory test passed 20 repeated runs. Removing the oversized-input guard fails the new error assertion; restoring it passes. - Package all-target Clippy, formatting, file-size checks, and pre-push Rust/Tauri checks passed. All executed hosted checks passed on the updated head (54 successful, 28 skipped). The separate Codex review comment still requests authorization for this exact range. - Earlier revisions passed the release build and a real Goose 1.51.0 tool-use smoke test. No new release artifact or installed Janet runtime is claimed for this feedback revision. - Repository-wide `just ci` was previously attempted; workspace Clippy passed, then the desktop dependency check stopped on a local pnpm fetch failure. Hosted checks cover the applicable PR lanes. --------- Signed-off-by: Logan Johnson <loganj@squareup.com> Co-authored-by: Larry <627498bd4bd1f281a16431e3c6cce3b5c25b6692798c78672298aefbf2f8f8b5@buzz.block.builderlab.xyz>	2026-09-24 10:58:15 -04:00
Mic Neale	4544ba1713	chore(mesh): upgrade MeshLLM to 0.76.2 (#7559) ... ## Summary Upgrade Buzz from MeshLLM `v0.76.0-rc9` to the latest stable [v0.76.2 release](https://github.com/Mesh-LLM/mesh-llm/releases/tag/v0.76.2) (via v0.76.1). - Update all eight Mesh git dependencies across desktop and relay smoke examples; both lockfiles resolve all 47 Mesh packages to `a0c1e66b0ac037dd56544b9e2d94969ea43d694f` (tag `v0.76.2`). All non-Mesh lock records are unchanged by the 0.76.1 → 0.76.2 bump. - Match Mesh's `ed25519-dalek = 3.0.0` and `rusqlite = 0.40` dependencies. - Explicitly enable rusqlite's `fallible_uint` feature, preserving Buzz's existing `u64` SQL conversions when **mesh is disabled**. Mesh-enabled builds previously supplied this transitively, so testing both configurations matters. - Temporarily pin **only** the optional `sqlx-sqlite` package to the merged upstream compatibility fix [transact-rs/sqlx#4402](https://github.com/transact-rs/sqlx/pull/4402), revision `94aafe3a68884d923b0798a767c8d7f6cfda89d2`. SQLx 0.9.0 caps `libsqlite3-sys` below 0.38, while Mesh 0.76 requires 0.38. Cargo resolves the conflict even with SQLite disabled. The fix raises that upper bound; remove the patch once released. Buzz's active PostgreSQL driver stays on crates.io SQLx 0.9.0. - Preserve the explicit Linux keyring 3 `crypto-rust` feature so Secret Service sessions retain DH encryption independently of Mesh keyring 4. - Preserve the dedicated examples-only `buzz-mesh-smoke` crate and lifecycle workflow wiring, keeping Mesh/native-runtime dev dependencies out of relay CI builds. - v0.76.1 → v0.76.2 upstream delta: self-updater fix for composed product-v2 bundles (Mesh-LLM/mesh-llm#1844) plus release plumbing — no API changes affecting Buzz. - Merged `origin/main` (`7c789dee0`) without rewriting shared PR history. ### Validation at `ae4adba15` (local macOS ARM64, Hermit toolchain) - **Passed:** `cargo test --locked -p buzz-mesh-smoke --all-targets` (all six example harnesses compile; no live harness execution). - **Passed:** desktop Tauri workspace tests, both default and `--features mesh-llm` graphs (3,296 tests with mesh enabled, 0 failures). - **Passed:** `just desktop-tauri-clippy` (both feature graphs, `-D warnings`), root workspace clippy `-D warnings`, `cargo fmt --all --check`. - **Passed:** `--locked` metadata resolution for both workspaces; lockfile diff audited to touch only Mesh package records. - **Passed:** full pre-push hook suite on the final push (branch-skew, rust-tests, desktop-tauri-checks, file-size-check) — no hooks bypassed. - **Not run:** live Mesh inference/admission smoke or installed-app UI exercise. CI lifecycle smoke coverage applies.

Kalvin C	5a349db91c	feat(relay): add opt-in newest-first thread windows (#7823) ... ## Summary Add an opt-in, newest-first thread window to the authenticated HTTP query path. A filter with `thread_window: true` returns: - reply rows ordered by `(created_at DESC, id ASC)` with an exact composite cursor; - optional bounded reactions, edits, deletions, and delete-of-aux closure; - one relay-signed `kind:39007` bounds event bound to the normalized host, authenticated reader, channel, root, request cursor, kinds, depth, limit, and aux choice. Filters without the flag keep the existing oldest-first thread behavior. Channel windows and `kind:39006` are unchanged. No client opts into this mode in this PR. ### Why extend NIP-CW NIP-CW already defines relay-computed, cursor-paged conversation views over extended NIP-01 filters. Thread windows use the same protocol ideas: ordinary signed rows, composite keyset pagination, optional aux closure, and relay-signed bounds. Adding a thread mode keeps those related wire contracts together instead of creating a second NIP with duplicated terminology and compatibility rules. Extending a draft, optional NIP with an additive mode is normal protocol evolution. Existing fields and meanings are not reinterpreted: - `top_level: true` remains channel mode; - `kind:39006` remains channel-window bounds; - `thread_window: true` selects the new mode; - `kind:39007` has a distinct identity and root/request binding; - extension-unaware clients never send the selector; - legacy thread queries remain unchanged. NIP-CW documents only the wire contract and relay semantics. Database plans, replica internals, and rollout procedures remain implementation concerns. ### Why thread windows use independent modules The implementation deliberately keeps `thread_window.rs` separate in `buzz-core`, `buzz-db`, and `buzz-relay` rather than adding branches throughout the existing channel-window path. The modes share pagination concepts, but their invariants differ: - channel mode selects top-level rows; thread mode requires one root and depths `1..=depth_limit`; - thread mode accepts only conversation row kinds and rejects unknown/conflicting fields; - thread bounds bind the root and authenticated reader because cross-channel aux visibility can differ by reader; - thread aux includes the root and requires complete two-hop closure; - thread mode refreshes writer authorization before selection and before signing; - historical cursor pages may use a proved replica transaction, but fallback must restart both aux hops on the writer; - legacy thread traversal is oldest-first and must not inherit descending cursor semantics. Forcing these rules into channel-window code would create a mode flag across parsing, SQL predicates, bounds construction, authorization, replica fallback, and tests. That abstraction would not remove complexity. It would distribute it. Separate modules keep each contract local and leave the established channel and legacy paths untouched. ### Technical design - Strict request parsing normalizes UUIDs, event IDs, kinds, defaults, and cursors before computing the response binding. - SQL applies community, root, channel, depth, kind, deletion, and cursor predicates before `limit + 1`. - Ordered metadata scanning plus exact event-key lookup avoids the stale-statistics plan that previously exceeded the four-second SQL budget on a 10k-reply thread. - Aux work is bounded by target batches, query count, raw candidate count, response bytes, SQL timeouts, and one shared HTTP deadline. - Fresh authorization-set comparison catches both grants and revocations during closure. The relay returns retryable `503` rather than signing an incomplete page. - Replica failure permanently degrades the request to the writer and restarts closure from its original targets without resetting budgets. - Migration `0049_thread_window_index.sql` adds the mixed-direction index used by newest-first scans. It validates a prebuilt index and bounds startup lock/build time. ### Tradeoffs - The stale-statistics-safe plan is intentionally less clever. Measured warm 100k deep-cursor execution increased from roughly 0.30 ms to 4.80 ms, plus about 8 ms planning, in exchange for avoiding a reproduced multi-second timeout after rapid 10k-thread insertion. - Bounds are authoritative only for the served page. There is no cross-page snapshot guarantee, and replica insertion coverage does not imply latest edit/deletion/aux visibility. - Strict parsing rejects unsupported constraints instead of silently serving a different row set. - Required aux closure fails closed. The relay does not omit aux and sign plausible-but-incomplete bounds. - This PR ships relay capability only. Client rendering, retry UX, live-history overlap, and compatibility fallback remain separate work. ### Related issue No existing issue found. This work follows the thread-loading design and review discussion. ### Testing - `cargo test -p buzz-core`: 258 unit tests and 2 doctests passed. - `cargo check --workspace --all-targets`: passed at the rebased implementation head. - `cargo test -p buzz-db`: 131 non-PostgreSQL tests passed; 275 infrastructure tests were ignored as declared. - Focused PostgreSQL migration/runtime regressions: 3/3 passed against an isolated PostgreSQL container, including both corrected migration-ledger tests. - `cargo fmt --all --check`: passed. - Pre-rebase feature validation passed 398/398 PostgreSQL tests, signed-wire multi-tenant/auth/pagination/aux/revocation probes, clean Compose boot/reboot, and full core tests. - Independent HA validation exercised three relay pods and a physical PostgreSQL standby on the same runtime logic before the final documentation-only cleanup. - Independent final-delta review confirmed exactly two changed files, byte-identical executable migration SQL after comments/diagnostic normalization, matching prebuild/catalog/recovery instructions, and `git diff --check`; no runtime receipts were relabeled to the new SHA. - The pre-push hook ran repository checks but its Rust unit lane exited 100 without exposing an individual failed test in the captured multiplexed output. The independently run affected-package checks above passed; current-head repository CI remains required. Known unrelated baseline behavior remains: the mesh-demo echo test can return 504, and same-second archive → unarchive can deduplicate its membership notification. Neither path is changed here. --------- Signed-off-by: Kalvin Chau <kalvin@block.xyz> Signed-off-by: cid <d9f92a72922bf45c17379a47d64dae84b6020397c2d5a52b5317d512068cd9d3@buzz.block.builderlab.xyz> Signed-off-by: am <6e30cd56c30e030cd31bb0939b94a7c257c9a09d5ba2d92cf2735da45629f248@buzz.block.builderlab.xyz> Co-authored-by: cid <d9f92a72922bf45c17379a47d64dae84b6020397c2d5a52b5317d512068cd9d3@buzz.block.builderlab.xyz> Co-authored-by: am <6e30cd56c30e030cd31bb0939b94a7c257c9a09d5ba2d92cf2735da45629f248@buzz.block.builderlab.xyz>	2026-09-23 12:01:45 -07:00
Salman Mohammed	5621006bcf	refactor: move agent Git bootstrap into ACP harness (#7819) ... discovered in https://github.com/block/buzz/issues/7742#issuecomment-5783512985 ## Summary Goose uses its native shell, so it bypassed the Git identity and signing setup inside `buzz-dev-mcp`. Agent commits could use the host Git identity, while MCP shells had a separate config. This moves Git setup into `buzz-acp`, where both paths receive the same agent identity, Nostr signer, and relay-scoped credential helper. Before: ```text Buzz Desktop └─ buzz-acp ← Desktop supplied relay Git authentication ├─ Goose → native shell ← no agent Git author or signing setup └─ Buzz Agent └─ buzz-dev-mcp └─ shell ← MCP created the keyfile and Git signing config ``` After: ```text Buzz Desktop or Sprig └─ buzz-acp ← owns the keyfile, identity, signing, and scoped credentials ├─ Goose → native shell ← inherits the complete Git environment └─ Buzz Agent └─ buzz-dev-mcp └─ shell ← receives the same Git environment via mcpServers[].env ``` The harness keeps the signing key in a private temporary file and removes it on normal exit, startup failure, and graceful termination. It composes inherited `GIT_CONFIG_*` entries, forwards the complete block to MCP servers, and bundles the helpers through the ACP multicall entrypoint. For standard `buzz-acp` launches, Desktop and Sprig no longer write Git config. A custom Desktop ACP command bypasses the harness, so Desktop preserves its prior relay-scoped credential helper for that supported override. This changes Git settings for every ACP runtime. The startup signal path also changes so a termination during adapter initialization removes the keyfile. The temporary file can remain after SIGKILL or a machine crash. ### Related issue Related: #6177 covers stricter commit identity enforcement and touches the same Git paths. That PR and this one need to be reconciled before either lands. No issue was found for this runtime bootstrap gap. ### Testing - Ran the ignored `git_runtime_tests` with real Goose 1.50.0 and Buzz Agent ACP sessions. `real_goose_native_git_shell` passed again on this PR branch with `BUZZ_TEST_BIN_DIR` pointing to built binaries. Goose made a signed commit and tag through its native shell; Buzz Agent did the same through its MCP shell. Both verified signatures, identity, credential scoping, and keyfile cleanup. - Built the Linux Sprig image and ran `scripts/test-sprig-image.sh buzz-sprig:acp-git-bootstrap`. The container made and verified a signed commit and tag, then confirmed keyfile removal after SIGTERM. - `just ci` passed on the original branch. After rebasing onto `main` and addressing review feedback, the ACP Git bootstrap integration tests, focused desktop smoke test, custom-command regression test, formatting, and ACP/Desktop Clippy passed. The pre-push hook hit two timing-sensitive ACP deadline tests under parallel load; both passed alone and the complete ACP package passed serially (964 library, 2 Git bootstrap, 9 pool lifecycle tests). The push used `--no-verify` after those checks; GitHub CI is rerunning on the new head. - Under injected `BUZZ_ACP_ALLOWED_RESPOND_TO`, `BUZZ_ACP_LAZY_POOL`, and `BUZZ_ACP_IDLE_POOL_SLEEP`, the clean-env serial package command in `crates/buzz-acp/TESTING.md` passed: 964 active library tests, 2 Git bootstrap tests, and 9 pool lifecycle tests. Both named Databricks OAuth tests passed locally; another reviewer reproduced their environment-specific failures on `main`. - No authenticated relay clone or push was run. The local probes used disposable repositories and did not contact a relay. Generated with Codex --------- Signed-off-by: Salman Mohammed <smohammed@squareup.com>	2026-09-23 14:41:00 -04:00

Salman Mohammed	4d08194ea9	Deduplicate thread context by ACP session delivery (#7620) ... ## Summary Buzz can repeat a thread reply in later prompts after the provider already received that event as context. The old fix treated every message signed by the agent key as retained by the current provider session. That could hide an unseen heartbeat reply because independent sessions share the same signing key. This PR now removes only exact event IDs already delivered to the live ACP session. It uses bounded overfetch so removed events do not shrink the new-context window, and it preserves unseen same-key replies from other sessions. The context header reports `truncated=true` whenever session history was omitted. The harness calls `/count` only when the relay query finds a sentinel beyond its fetch window. This deliberately does not parse event IDs from shell output. A reply that the agent just published may appear once in the next context delta; after that event reaches the provider as context, later prompts omit it. --------- Signed-off-by: Salman Mohammed <smohammed@squareup.com>	2026-09-15 10:24:27 -04:00

Wes	4cd82f5132	feat(buzz-agent): add opt-in workspace-scoped Databricks reuse (#7606) ... Posted by Brain, Wes Billman’s AI assistant, on behalf of `wesbillman`. ## Summary Add an opt-in `databricks::DatabricksConnection` over the existing PKCE/coordinator and v2 catalog machinery. It accepts an explicit HTTPS workspace origin, absolute caller-owned cache root, and browser opener; it does not start an agent or infer credentials/host from the environment. - Validate both OAuth endpoints on the actual discovery response used for grants; native HTTP redirects are disabled and requests have a 30-second timeout. - Keep strict cache/single-flight state in a separate namespace. Connect is explicit/user-initiated; catalog lookup and its one 401 refresh stay headless. Tokens are not exposed by the connection API. - Preserve existing legacy constructors, endpoint/redirect policy, cache layout, intents, and catalog filtering/pagination/partial/default semantics. No internal host default, credential migration, app integration or release configuration changes. ### Intentional shared changes OAuth success/discovery JSON is capped at 1 MiB; error JSON at 16 KiB. Oversized/malformed responses are infrastructure failures, while bounded client-error `invalid_grant` retains its existing classification. OAuth diagnostics omit raw bodies/URLs/opener/callback details. Overflowing token expiry returns an infrastructure failure. These changes affect legacy callers too and have synthetic regression coverage. See [the reuse contract](crates/buzz-agent/DATABRICKS_REUSE.md) for API, compatibility and caller obligations. Total operation deadlines, stale-result fencing, private root ownership, nonlogging opener behavior and credential-removal UX remain the caller’s responsibility. ### Related issue Related discovery work: #6918. Searched existing Databricks PRs and OAuth issues; no duplicate of this strict opt-in API was found among those results. This is a new reuse boundary, not a claim of a live credential leak. ### Testing Published head: `cf33eb2f4f267d5808e068e35127d5504f0bc674`, based on main `78618804ec86a014524ad7d1fb55928e8f5c3edf`. Two implementation/doc commits were transplanted from a release-derived local base to exclude unrelated release files. `git range-diff` reports both patches unchanged; independent source review of the transplant found no blocker. **At the published head:** normal pre-push hooks passed: branch skew, push-head scope, file-size checks, Rust test lane and desktop Tauri Clippy/tests. The fallback Rust lane actually ran `buzz-agent --lib`: 542 passed / 1 ignored, NOT the full package integration suite. Hosted full package/repository CI remains pending. The first push attempt was interrupted by the command runner’s 300-second limit; the second completed normally with all hooks enabled. **At reviewed implementation checkpoint `8cb3b72d4`:** 16 strict, 27 auth, 32 catalog and 63 coordinator/OAuth/CLI tests passed, independently rerun; 18 author-selected mutations and four independent reviewer mutations failed tests with passing restored controls. The subsequent `539319411` delta changed only two doc-comment blocks. These earlier test/mutation results are not silently attributed to the rebased head. Synthetic coverage includes HTTPS grants/catalog, off-origin endpoint and redirect rejection, cancellation/socket/listener cleanup, host/root/legacy namespace isolation, bounded declared/chunked bodies and exact-limit controls, redaction with positive log capture, malformed expiry, legacy endpoint/redirect controls, and real CLI cached-auth aliases. Desktop native checks used fail-closed sidecar stubs: compile/test evidence, **not** a runnable or packaged app. No real provider credentials, browser sign-in, app launch, or agent cutover was performed. Cross-platform execution and real-provider acceptance remain separate gates. No merge or downstream adoption is requested by this PR. --------- Signed-off-by: Brain <1a02c72794dcd0f07058a353bc3a81f4028b8c77c92c87fce6d5c8b85970a20b@buzz.block.builderlab.xyz> Co-authored-by: Brain <1a02c72794dcd0f07058a353bc3a81f4028b8c77c92c87fce6d5c8b85970a20b@buzz.block.builderlab.xyz>	2026-09-13 08:04:56 -06:00
Mic Neale	44316ff72f	feat(mesh): upgrade to mesh-llm 0.76.0-rc8 and recommend Qwen3.8 27B (#6189) ... Upgrades Buzz's mesh-llm dependencies through the released `v0.76.0-rc8` tag (`2040765d`), including the Qwen3.8 curated recommendation and rc8's scheduler/runtime improvements. **Scope note:** the earlier open-relay/unenforced-admission mode has been removed from this PR at Mic's direction — it is not a product mode we want. Mesh admission remains roster/allowlist driven, exactly as on `main`: on a relay with no NIP-43 membership snapshot the mesh runs self-only. No NIP-11 mode probing, no mode-transition restarts. A future perimeter/admission strategy for open relays will be designed separately. This PR also: - seeds `BUZZ_AGENT_LLM_TIMEOUT_SECS=660` for mesh agents, above MeshLLM's 600-second backend timeout; - makes `desktop-tauri-clippy` lint both default and `mesh-llm` cfg graphs; - runs the feature-enabled desktop test suite in CI; - recommends Qwen3.8 27B Q4_K_M for 64 GB-and-larger machines, then ladders down through Gemma 4 E4B and Qwen 9B for smaller machines; - keeps stored shared-compute `auto` translated to MeshLLM's supported wire model `mesh`. RC8 verification: - `just ci` passed locally at `92ecc7ec933bdd4df804cc9f28a2b51efa5313c5`. - Pre-push differential gates passed, including both desktop Tauri cfg graphs and package tests. - A prior isolated runtime smoke used the RC8 binary's OpenAI endpoint for a Buzz-shaped system/user/tool/tool-result/final-response loop; all assertions passed and the isolated process was shut down.

Will Pfleger	5aed49b505	feat(buzz-agent): add DatabricksAuthCoordinator single-flight OAuth (#5545) ... ## What Consolidates all Databricks OAuth acquisition behind one coordinator on `PkceOAuthTokenSource`. Every entry point — the four `TokenSource` methods (`bearer`, `bearer_no_browser`, `refresh_now`, `interactive_login`) plus the public `acquire_with_intent` — routes through a single `acquire()`/`acquire_locked()` core that owns browser and cooldown policy. Before this, acquisition logic was scattered across those methods with no coordination: concurrent callers (Desktop discovery, the saved-agent model picker, managed-runtime inference) could each pop their own browser, and a just-denied attempt would immediately re-prompt on the next passive read. ## How - **Intent policy.** `AuthIntent::{Auto, UserInitiated, Headless}` decides whether a caller may open a browser and whether it honors the cooldown. `Headless` never browses; `Auto` browses but honors an unexpired cooldown; `UserInitiated` browses and bypasses+clears the cooldown. - **Two-layer single-flight per cache key.** An in-process registry (`INFLIGHT`) coalesces same-key, same-intent callers onto one leader's attempt before the file lock. The slot key is `(lock_path, AuthIntent)`, so a `UserInitiated` sign-in never inherits an `Auto` leader's result. A joined result is revalidated against the waiter's own contract. Across processes, callers serialize on a `flock`-based advisory lock and share success through the on-disk cache. RAII `Drop` releases both lock and leader slot. - **Joiner credential-state reconciliation.** `SlotPublish` carries the full `CachedToken` on success. Each joiner reconciles its own independent `state` cell under `state.lock().await` before returning: adopt when absent, expired, or matching the joiner's rejected credential; preserve any distinct newer usable credential. On a matching shared failure, neutralize the joiner's in-memory rejected entry under lock via `expire_rejected_memory` — durable disk mutation is reserved for `acquire_locked` under the cross-process file lock. Without this, a joining source's state remains stale or empty and subsequent plain `bearer()` calls resurface the rejected or absent credential. - **Validate-before-persist boundary.** `finish()` is the candidate-token persistence boundary for refresh and browser results. Before a token is written to cache or the cooldown is cleared, a bearer equal to the caller's rejected bytes yields a typed failure. - **Token neutralization.** When `acquire_locked` enters with `rejected = Some(bytes)`, it calls `expire_rejected()` under the state lock before any cache check. - **Cross-process failure single-flight.** An `AttemptRecord` sidecar records a monotonically-increasing generation, intent, result code, and SHA-256 digest of the completing caller's rejected token. Adoption is temporal (pre-queue snapshot predates current generation) and digest-matched. - **Typed outcomes.** `AuthError` with stable `code()`/`from_code()` replaces display-text matching. - **Durable cooldown sidecar.** Every failed browser attempt is recorded next to the cache key. 5-minute expiry. - **Windows disk persistence disabled.** On non-Unix platforms, `persist()` is a no-op. Lock, cooldown, and attempt sidecars are active on all platforms. Tests that seed or assert on the on-disk token cache are `#[cfg(unix)]`-gated. - **Injected browser opener** invoked while the localhost callback listener is live. ## Tests - `crates/buzz-agent/tests/databricks_auth_coordinator.rs`: browser/cooldown/classification acceptance matrix with a scripted `BrowserOpener` and stub OIDC provider. P1 regressions exercise the full `finish()` → `acquire_locked()` → `acquire_leader()` → `LeaderGuard::complete()` → joiner wiring: - `test_inprocess_joiner_reconciles_stale_state_after_shared_success` (Unix): two real sources both loaded locally-fresh-but-rejected X; after shared success Y, subsequent plain `bearer()` on both returns Y, not X. - `test_inprocess_joiner_neutralizes_rejected_on_matching_shared_failure` (Unix): B's matching rejected X is force-expired in memory after shared `RefreshRejected`; subsequent read cannot return X. - `test_inprocess_joiner_populates_empty_state_no_second_acquisition` (non-Unix): empty A/B join a browser success; B's subsequent headless read returns Y without a second browser (no disk fallback on non-Unix exposes the regression). - `test_crossprocess_userinitiated_waiter_adopts_predecessor_denial` (snapshot-marker barrier replacing an earlier sleep for deterministic generation ordering). - `auth.rs` in-crate tests: lock-primitive edges, disk-recheck on shared failure (`#[cfg(unix)]`), and: - `test_joiner_reconciliation_blocked_until_state_lock_released`: deterministic direct-poll proof that awaited reconciliation requires `state.lock().await`. The test task holds B's state mutex and manually polls a pinned real `acquire()` future — Poll 2 (slot published, mutex still held) must return `Pending` because `lock().await` blocks; with `try_lock` instead, Poll 2 returns `Ready`, failing the assertion. - `test_joiner_preserve_distinct_newer_credential`: deterministic direct polling parks B at `slot.wait()`, then writes Z directly into B's state in the same task, then publishes Y and awaits completion. B must return Y but leave state == Z. Mutation check: unconditional adoption overwrites Z with Y, failing the state assertion. - `test_joiner_shared_failure_recovers_disk_replacement` (Unix): the matching-failure joiner enters the recovery branch — after `expire_rejected_memory` (in-memory, empty state no-op) it reads a sibling-written disk replacement via `usable_from_disk` and returns it. Mutation check: removing the `usable_from_disk` recovery branch returns `Err(RefreshRejected)`. - `test_joiner_failure_does_not_write_disk` (Unix): byte-for-byte disk-invariance regression — a matching-failure joiner calls `expire_rejected_memory` and must not touch the on-disk cache. An independent process C may write a valid replacement between A's failure and B's reconciliation; this guard ensures B's unfenced in-memory neutralization cannot overwrite C's concurrent disk write. Mutation check: reverting to `expire_rejected` rewrites the file (`expires_at = 0`), changing the bytes and failing the assertion. - `test_lock_timeout_leaves_cooldown_sidecar_byte_for_byte_untouched`: a waiter past its deadline returns `LockTimeout` before entering `acquire_locked`; the cooldown sidecar bytes are unchanged. Documents a pre-lock limitation: `LockTimeout` callers do not neutralize state or sidecars. ## Scope / follow-ups - **Runtime 401 handling is deferred.** This PR owns acquisition single-flight and policy. - **Desktop wiring is Phase 2** (not in this PR's boundary). Confined to `crates/buzz-agent/`. - **Windows DACL** is a follow-up once the `windows-sys` binding is available. ## Stack Built on [#5534](https://github.com/block/buzz/pull/5534) (`hayt/databricks-oauth-cache-hardening`), now merged.

Will Pfleger	70895b355f	feat(buzz-auth): add production NIP-FI federated assertion runtime (#7109) ... Depends on #6994 (merged). Stack: PR 2 #6994 (merged) → this PR (#7109) → PR 4 #7148 → PR 5 ## What Production assertion runtime for NIP-FI Phase A: JWKS caching layer, SSRF-hardened HTTP fetcher, startup validation gate, NIP-11 discovery serialization, federated assertion verifier with sealed key-source authority, and supporting invariant tests. ## Changes ### `crates/buzz-auth/src/nip_fi/jwks/` `ProductionJwksSource<F>` implements the sealed `IssuerKeySource` trait: - `HttpJwksFetcher`: reqwest-backed fetch with SSRF protection — URI validation (HTTPS, no credentials, no fragment, no host matched by the shared enumerated deny policy), per-fetch DNS resolution rejecting any resolved address matched by the shared enumerated deny policy, address pinning to prevent DNS rebinding TOCTOU, redirect denial, incremental body streaming capped at 512 KiB before any parse - IPv6 host extraction via typed `Url::host()` accessor (strips brackets before SSRF check and provides the correct bare input form for reqwest `resolve()` pinning; the bracketed form from `host_str()` fails `IpAddr::parse` and does not match the URL authority key) - Complete-operation deadline via `tokio::time::timeout` covering DNS resolution through body streaming - Bounded periodic refresh with configurable interval and hard snapshot deadline - Cancellation-safe RAII refresh permit: dropped on future cancellation so the next caller can re-fetch - Content-digest-gated generation counter: identical re-fetches preserve generation; key rotations advance it - Injectable clock (`now_fn: Arc<dyn Fn() -> DateTime<Utc> + Send + Sync>`): production uses `Arc::new(Utc::now)`; all four deadline creation and expiry checks use `(self.now_fn)()`, enabling controlled-time testing without wall-clock sleep `JwksSourceContract`: a closed value type that is the single source of truth for the three deployment fields whose change alters which keys the runtime trusts and how long it trusts them: - `jwks_uri` — selects the authenticated key source; validated at construction (HTTPS, no credentials/fragment, no bare private-IP host); stored as the `Url`-normalized form so that equivalent spellings (uppercase host, explicit default port `:443`, dot-segment paths like `/.well-known/./jwks.json`) converge to the same `AssertionPolicyId` - `refresh_interval_seconds` — defines bounded refresh behavior; positive, ≤ 1 year, strictly < `key_snapshot_hard_deadline_seconds` - `key_snapshot_hard_deadline_seconds` — defines the source's accepted time rule; every `VerifiedAssertion.revalidation_dependencies` deadline derives from this `JwksSourceContract` is a required `IssuerPolicy` input and is included in `derive_assertion_policy_id` after a domain separator. `IssuerJwksConfig` embeds the contract instead of independently restating these fields — startup validation rejects any contract mismatch (`NipFiStartupError::JwksContractMismatch`). ### `crates/buzz-auth/src/nip_fi/verifier.rs` - `FederatedAssertionVerifier<S>`: provider-neutral verifier over a closed multi-issuer registry and sealed `IssuerKeySource` - `Arc<S>: IssuerKeySource` forwarding impl (blanket seal for `Arc<S>` in the sealed module) — one `Arc<ProductionJwksSource>` can be shared across multiple verifiers; all observe JWKS refreshes through the shared cache without rebuilding the verifier - `AssertionKeySet`: crate-private constructor seals issuer binding — no external crate can relabel issuer B's JWKS as issuer A - Sealed `IssuerKeySource` trait closes the authority-construction seam at both ends ### `crates/buzz-core/src/network.rs` Renamed `is_private_ip` to `is_not_global_unicast` (compat alias retained) and restored the complete IANA deny/exception table from this branch's own history (`272dacadb`). The predicate is an enumerated deny/explicit exception policy: addresses covered by a named deny rule are rejected; addresses not covered by any explicit deny rule (e.g. `fe00::1`) pass through. Deny rules are derived from the IANA Special-Purpose Address Space registries (last updated 2025-10-09), with globally-reachable exceptions carved out explicitly (e.g. PCP/TURN anycast inside 2001::/23). Blocked IPv4 classes: loopback (127/8), private RFC 1918 (10/8, 172.16/12, 192.168/16), link-local (169.254/16), unspecified (0/8), broadcast, CGNAT/RFC 6598 (100.64/10), benchmarking/RFC 2544 (198.18/15), IETF Protocol Assignments (192.0.0.0/24, globally reachable exceptions: 192.0.0.9 PCP anycast RFC 7723 and 192.0.0.10 TURN anycast RFC 8155), documentation/RFC 5737 (192.0.2/24, 198.51.100/24, 203.0.113/24), deprecated 6to4 relay anycast (192.88.99.0/24, RFC 7526, global=None → conservative deny), multicast/RFC 5771 (224/4), reserved class-E (240/4). Blocked IPv6 classes: loopback (::1), unspecified (::), ULA (fc00::/7), link-local (fe80::/10), deprecated site-local (fec0::/10, RFC 3879), multicast (ff00::/8), IETF Protocol Assignments envelope (2001::/23, globally reachable exceptions: 2001:1::1–::3 PCP/TURN/DNS-SD anycast, 2001:3::/32 AMT RFC 7450, 2001:4:112::/48 AS112-v6 RFC 7535, 2001:20::/28 ORCHIDv2 RFC 7343, 2001:30::/28 DETs RFC 9374), documentation (2001:db8::/32 RFC 3849, 3fff::/20 RFC 9637), 6to4 (2002::/16, RFC 3056), Discard-Only (100::/64, RFC 6666), Dummy IPv6 Prefix (100:0:0:1::/64, RFC 9780), SRv6 SIDs (5f00::/16, RFC 9252), NAT64 local-use (64:ff9b:1::/48, RFC 8215). IPv4 embedded in mapped, compatible, NAT64 well-known (64:ff9b::/96), and SIIT IPv4-translated (::ffff:0:0:0/96) forms is checked recursively. All three callers (JWKS boundary, webhook SSRF, link-preview SSRF) inherit the complete predicate through the inline `is_private_ip` compatibility alias. ### Invariant coverage **Canonical URI convergence.** `jwks_contract_uri_canonicalization_convergence_and_divergence` asserts that uppercase host, explicit `:443`, and dot-segment path (`/.well-known/./jwks.json`) each produce the same `AssertionPolicyId` as the canonical form; a genuinely different host or path diverges. Mutation: storing raw input bytes instead of `parsed.to_string()` turns the three convergence assertions red. **Resolved-target and pin-input seam.** `resolved_target_and_pin_key_seam_public_ipv6_and_fec0_rejection` carries a public `2606:4700::1` URI through all three stages of `fetch_jwks_inner`: `extract_url_host_and_port` yields the bare host (no brackets), `resolve_and_check_ssrf` takes the IP-literal fast path and returns the accepted `IpAddr`, and the extracted host string equals the URL authority form (verifying the correct bare input to reqwest's `resolve()` pin call). `fec0::1` traverses the same extraction and SSRF stages and is rejected as `InvalidUri`. Network-free: both addresses are IP literals with no DNS lookup. Mutation: restoring `host_str()` brackets the address, `IpAddr::parse` fails, the SSRF fast path is unreachable, and all three assertions flip red. **Controlled original-deadline rotation.** `shared_arc_source_verifier_rejects_expired_a1_accepts_a2` uses an `AtomicI64`-backed injectable clock to advance past A1's original absolute deadline without wall-clock sleep. A1's deadline is computed at T0 and never mutated. The clock advances to T0 + HARD_DEADLINE_SECS + 1; `get_snapshot` fires a re-fetch and installs A2. One unchanged `FederatedAssertionVerifier` then rejects A1-signed tokens (deadline enforced by the `key_set` read path) and accepts A2-signed tokens, proves A2's generation is strictly greater, and confirms A2's deadline is later than A1's original. Mutation oracle: replace the shared `Arc` with an independently constructed source built from the same configs and sharing the same controlled clock, warmed with a separate A1 fetch before advancement. Post-advancement, `key_set()` on the verifier's independent source filters the expired A1 snapshot (`filter(|c| now < c.hard_deadline)`) and returns no keys — the verifier never re-fetches and never observes A2. A1-reject stays green (the independent cache is also expired, so no A1 keys are served), but A2-accept flips red, because the verifier never observes A2. A2 acceptance is the reliable shared-source oracle. **Complete SSRF classifier boundary.** JWKS-boundary tests cover every newly restored class through `validate_jwks_uri` (URI-validation path): `192.0.0.1` (IETF Protocol Assignments interior), `192.0.0.9`/`.10` (PCP/TURN anycast global exceptions), `192.88.99.1` (deprecated 6to4 anycast), `2001:2::1` (2001::/23 interior), `2001:1::1` (2001::/23 global exception), `100::1` (Discard-Only), `3fff::1` (documentation), and `5f00::1` (SRv6 SIDs). URI validation and resolved-target enforcement share the same `is_not_global_unicast` predicate, so these URI-path tests exercise the complete classifier table. All pass mutation: removing any deny branch makes the rejection assertion red; removing any exception branch makes the acceptance assertion red. The resolved-target enforcement path is covered separately by `resolved_target_and_pin_key_seam_public_ipv6_and_fec0_rejection` for `::1` (loopback), public `2606:4700::1`, and `fec0::1`. --------- Signed-off-by: Will Pfleger <pfleger.will@gmail.com> Co-authored-by: Duncan <dcfd242e557282d7a1e2cf2e6877522682f1e5c6156dc92ca7d90eaedd3b0f95@buzz.block.builderlab.xyz> Co-authored-by: Cea Stapleton Cordasco <261786559+cea@users.noreply.github.com>	2026-09-01 13:00:40 -04:00
Tom Brow	c432a111ca	feat(mobile): push notifications MVP (#6269) ... This PR implements MVP, iOS-only, [NIP-PL](8d2d0ff5ad/docs/nips/NIP-PL.md)-compliant push notifications. A relay with `BUZZ_PUSH_ENABLED` will send a push notification for any message that appears in the in-app Notifications tab. ## Enrollment flow The first time the client first connects to a relay with `BUZZ_PUSH_ENABLED`: ```mermaid sequenceDiagram autonumber participant App as Buzz iOS app participant iOS participant Relay as Buzz relay participant Attest as Apple App Attest participant Gateway as Push gateway App->>Relay: Fetch NIP-11 push capability Relay-->>App: Push profile, current relay public key, and limits par App->>iOS: Request notification permission iOS-->>App: Permission result and App->>iOS: Register for remote notifications iOS-->>App: Device token end App->>Gateway: Request installation challenge Gateway-->>App: Single-use challenge App->>Attest: Attest installation transcript Attest-->>App: Attestation proof App->>Gateway: Enroll device token and proof Gateway-->>App: Installation handle App->>Gateway: Request delegation challenge Gateway-->>App: Single-use challenge App->>Attest: Assert relay-key delegation Attest-->>App: Assertion App->>Gateway: Create delegation Gateway-->>App: Opaque endpoint grant App->>Relay: Publish encrypted push lease and filters Relay-->>App: Lease acknowledged ``` ## Push-time flow When a notification-eligible event is received by the relay: ```mermaid %%{init: { "sequence": { "actorMargin": 20, "width": 110, "messageMargin": 18, "diagramMarginX": 8, "wrap": true } }}%% sequenceDiagram autonumber participant Relay as Buzz relay participant Gateway as Push gateway participant APNs as Apple Push<br/>Notification service participant iOS participant NSE as Notification service<br/>extension Relay->>Gateway: POST /v1/deliveries/apns<br/>opaque endpoint grant, request ID, expiry, NIP-98 authorization Gateway->>APNs: POST /3/device/{device-token}<br/>topic, request ID, expiry, constant mutable-content payload APNs-->>Gateway: 200 OK: request accepted Gateway-->>Relay: 200 OK: accepted status APNs-->>iOS: Notification: constant reconnect alert<br/>mutable-content = 1 iOS->>NSE: Invoke extension<br/>original notification content NSE->>Relay: POST /query: subscription filters, limit 10<br/>NIP-98 authorization Relay-->>NSE: 200 OK: signed Nostr events<br/>kinds 9, 40002, 45001, or 45003 NSE->>iOS: Complete notification: title, body, subtitle<br/>thread ID, exact-message target ``` relay → push gateway → APNs -> NSE -> Notification Center ## Known limitations The APNs wake payload is intentionally constant and opaque: it contains no originating community or message identifier, in keeping with the implemented NIP-PL privacy design. The Notification Service Extension must therefore reconnect to the relay and resolve eligible messages after each wake. Around overlapping wakes, timing boundaries, or resolution windows, notification presentation may occasionally omit an expected message or display a message more than once. This best-effort behavior is deliberately accepted for the current implementation and will be measured during the internal rollout to determine whether the user experience is acceptable before any broader deployment; the implementation does not claim exactly-once presentation. ## Validation Live end-to-end hardware validation used an internal remotely hosted development relay and push gateway, the APNs sandbox, and a physical iPhone 12 mini: - A second real Buzz client published a uniquely marked message through the hosted relay. - The relay matched the message and sent the constant opaque wake through the hosted gateway. The gateway made an actual APNs request; no `simctl push` or simulated notification was used. - The iPhone received the notification on its lock screen. The Notification Service Extension reconnected to the relay, fetched the event, verified its ID and signature, and replaced the placeholder content with the real notification title and body. - After the app populated its shared presentation cache, a final marked notification visibly showed the sender display name, sender avatar, and hashtag-prefixed channel name. - Tapping a lock-screen notification opened Buzz and exercised the notification-response path and navigated to the corresponding message. Final validation with a dogfood-signed artifact and production App Attest/APNs configuration remains a release step. ## Independent pre-reviews - **First pass:** [Carl](buzz://message?channel=18882f4c-289f-41db-942f-81f6f8066da1&id=74ab9a93bb227f3e762568f1cf9fee66d7495b0edc3918735ff787238b9cc585) found missing transient retries, executor-key rotation suppression, duplicate installation renewal, and an unauthenticated challenge write amplifier.

Will Pfleger	953a1798b2	feat(auth): add NIP-FI canonical assertion verifier and contracts (#6776) ... The closed, provider-neutral contract layer at the root of the NIP-FI federated-identity dependency graph — Phase A, PR 1 of the plan. It has no dependencies on any other PR and defines no database schema, migration, runtime JWKS fetching, binding resolution, enrollment, or request/proof binding; those belong to later PRs. ## What this adds - **Multi-issuer assertion-policy config** (`IssuerRegistry`, `IssuerPolicy`) keyed by exact `iss`. Identity is issuer-qualified `(iss, sub)` throughout — equal `sub` under different `iss` are distinct identities. The subject coordinate is fixed to the JWT `sub` claim (`SUBJECT_CLAIM`), never configurable, so no deployment can seal a mutable attribute like `email` as identity. Issuer URL and audience remain deployment configuration. - **The two deterministic semantic contract identities** — `AssertionPolicyId = H(canonical assertion-policy contract)` and `TransportContractId = H(canonical transport contract)` — derived by length-prefixed, domain-separated SHA-256 so a semantic change moves exactly its owning ID while benign JWKS rotation never changes policy lineage. Set-valued policy inputs (audiences, algorithms, subject-class values, scope capture) are canonicalized before derivation, so the ID is invariant under permutation and duplication. Config fields that a freshness class never reads are rejected at construction (an `offline-jwt` policy cannot carry `maximum_status_age`), so the canonical encoding stays total over valid configs and semantically identical policies always derive one ID. - **The single canonical verifier** (`FederatedAssertionVerifier`, `FI-INV-16`) producing the origin-sealed, provider-neutral `VerifiedAssertion` normalized result. Its constructor is crate-private, so unverified claims cannot be promoted into authority. The issuer→JWKS authority is entirely crate-owned: `AssertionKeySet` has no public constructor and `IssuerKeySource` is sealed, so no downstream crate can relabel one issuer's keys as another's. The authenticated key set is bounded (`MAX_JWKS_KEYS`) and the bound is folded into `AssertionPolicyId`, so an unbounded attacker-controlled `kid` scan cannot be driven; every snapshot requires a finite positive hard deadline. - **Sealed revalidation dependencies** — `RevalidationDependencies` carries the key-snapshot hard deadline and a `ConfidentialAssertion` handle to the exact compact JWS (no `Debug`/`Display`/`serde` leak, sole read path `compact_jws()`), so a changed snapshot can revalidate the same evidence: a retained key revalidates, a removed key denies. - **The privacy-preserving four-class denial contract** (`DenialClass`, `FI-INV-13`) with the byte-exact Nostr text, HTTP status, body, `Content-Type`, and `WWW-Authenticate` values fixed by the spec's rejection table. An unreadable required current dependency maps to `authorization_unavailable`/503, never to rejected evidence, and rejected evidence never masquerades as a 503 at either end of the pipeline: all bounded, dependency-independent checks (compact structure, header, signature shape, policy, algorithm, token class) precede key-source lookup, and all offline validation (token-class, key, signature, audience, claims, time) completes before any status-witness deferral. A wrong-`typ` or structurally malformed token, or malformed/invalidly-signed input naming a current-status issuer, therefore denies with `evidence_rejected`/403 rather than being reported as a 503 availability signal. ## Corrections applied to the mined source Mined from the `buzz-auth` verifier core in [#1476](https://github.com/block/buzz/pull/1476) and corrected to the settled spec (the merged `docs/nips/NIP-FI*.md`, [#5946](https://github.com/block/buzz/pull/5946)), which settled after #1476 was written: - Token-class selection with exact `typ` enforcement. Two classes are offered: `at+jwt` and `nip-fi+jwt`. There is deliberately no generic/absent-`typ` "named compatibility" class: it cannot be proven disjoint from an OIDC ID token by claim presence alone (an issuer can mint an ID token carrying `client_id`), and the only authenticated discriminator is `typ`, which such a mode declines to constrain. - OIDC ID-token denial — denies even when `iss`, `aud`, and `sub` match, via exact `typ` mismatch against every accepted class. - The fixed `nostr_pubkey` claim accepted only as lowercase hex of exactly one 32-byte key; bech32 and other aliases deny. - Resource-owner / client-subject ambiguity denial and required `client_id` for `at+jwt`. - JWK admissibility: a key's `use` and, when present, `key_ops` must authorize signature verification (a key restricted to other operations such as `encrypt` is rejected), and the selected JOSE algorithm is bound to the key's required family and curve (ES256↔EC/P-256, ES384↔EC/P-384, EdDSA↔OKP/Ed25519, RS/PS↔RSA). The JWK `alg` is advisory; the actual key material is what signs, so a JWK declaring a matching `alg` over mismatched material (a different family or curve) is rejected before signature verification. - Spec-exact time arithmetic (`now < exp`, `iat <= now + skew`, `now < iat + maximum_assertion_age`, equality at expiry is expired). `exp`/`iat`/`nbf` accept finite integer or fractional RFC 7519 `NumericDate` values with checked, overflow-safe conversion; non-finite and out-of-range values deny. ## Verification In-crate tests in `crates/buzz-auth/src/nip_fi/verifier/tests.rs` sign real ES256 assertions against a fixed test key and cover: the happy path, exact-wire-text for all four denial classes, deterministic and semantic contract IDs, canonicalization invariance, token-class enforcement including ID-token denial, JWK `key_ops` rejection, `nostr_pubkey` hex handling, time bounds, and multi-issuer selection (same subject across distinct issuers yields distinct identities and policy IDs). They also cover the round-3 contracts: the key-set bound (oversized rejected, at-bound accepted, empty rejected), fixed-`sub` identity (identity is `sub` not a configured `email`; a token without `sub` denies), offline-before-deferral (invalid-signature, wrong-audience, malformed-claim, and expired under a current-status issuer each deny 403/`evidence_rejected`), and the revalidation contracts (dependencies carry the deadline and exact JWS; a retained key revalidates, a removed key denies). And the round-4 contracts: algorithm↔key-material binding, covered exactly per accepted algorithm (a table-driven matrix asserts every policy-acceptable algorithm — ES256, ES384, EdDSA, RS256/384/512, PS256/384/512 — matches only its required family/curve and rejects every other, so each mapping mutation fails individually; and an ES256 token against P-384, RSA, and Ed25519 material each deny `InvalidKey`); malformed evidence classified before key lookup (wrong-`typ`, two-segment, four-segment, empty-signature, and non-base64url-signature tokens against an empty source deny 403 not 503); `maximum_status_age` inapplicable under offline-jwt rejected at construction while current-status still requires it; and fractional `NumericDate` (finite fractional `iat`/`exp`/`nbf` within bounds verify, non-finite and out-of-range deny). Compile-fail doctests guard the sealed authority seam (`AssertionKeySet::new`, `IssuerKeySource`) and the absence of the named-compatibility token class. ## Notes - `Co-authored-by` attribution is preserved for the mined author. The #1476 `buzz-auth` commits are authored by Cea Stapleton Cordasco (the salvage map records #1476 under Franco; the git history on that PR is Cea's — surfacing for the attribution/closure record). - Amends `docs/nips/NIP-FI.md` to remove the "named compatibility access token" class and its `FI-TRACE-TOKEN-CLASS` oracle reference, so the normative spec matches the two-class root implementation (a generic/absent `typ` cannot be proven disjoint from an OIDC ID token). Removal-only, no neighbor redesign; a `docs/nips/` grep confirms no dangling cross-reference to the class remains. - Adds `jsonwebtoken 10.4.0` (`aws_lc_rs`) as a workspace dependency.

Luke Tornquist	113a33b7e4	Add database pressure observability (#6700) ... ## Why Database pressure currently collapses several distinct delays into one symptom. This adds the evidence layer needed to distinguish pool acquisition wait, logical database operation time, advisory-lock wait, and selected transaction duration before changing timeout or retry policy. This is the phase 2 Lane A observability bundle for [#26](https://github.com/TheSentinel454/buzz/issues/26), [#28](https://github.com/TheSentinel454/buzz/issues/28), and [#33](https://github.com/TheSentinel454/buzz/issues/33). It is stacked on #6668. ## What - Record explicit reader/writer checkout wait and acquisition outcomes with `buzz_db_pool_acquire_wait_seconds` and `buzz_db_pool_acquisitions_total`. - Extend the compile-time `#[datastore_span(name = "...")]` seam with `buzz_db_operation_duration_seconds`, so operation labels remain static source literals instead of request data. - Route correctness-critical replacement, membership, push-gate, deletion, and migration/schema-safety advisory locks through one observer without changing their SQL, order, scope, or blocking behavior. - Measure six internally owned transaction lifetimes with `buzz_db_transaction_duration_seconds`, starting after `BEGIN` succeeds and ending after explicit commit/rollback or scope exit. - Emit root slow-operation warnings at 500 ms, logging the first slow completion and then 1/100 per call site with only `operation`, `outcome`, and `elapsed_ms`. - Document names, units, fixed label vocabularies, measurement boundaries, and blind spots in this PR description. Fixed labels are deliberately small: - `pool_role`: `writer`, `reader` - `lock_type`: `replacement`, `membership`, `push_gate`, `deletion`, `migration_schema_safety` - `outcome`: `success`, `error`, `timeout` where SQLx/PostgreSQL can distinguish it accurately - `operation`: compile-time datastore names plus the six closed transaction operation names documented in the runbook No metric or slow warning contains community IDs, event IDs, event kinds, coordinates, d-tags, SQL/query text, query IDs, returned errors, or event content. ## Coverage boundaries - Operation duration is the complete annotated logical function body, not pure SQL execution; it may include implicit checkout, lock wait, nested operations, and application work. Cancelled futures do not reach its completion hook. - Pool timing covers explicit helper checkouts, including proved-reader routing and selected writer-owned transactions. Implicit SQLx checkout through `&PgPool` remains folded into operation duration. - Lock timing covers application-side blocking locks in the five named families. Trigger/stored-procedure locks, channel-TTL locking, the usage try-lock, and the audit service session lock remain outside this slice. - Transaction timing covers only the six wholly owned boundaries documented in the runbook. It excludes pool wait, `BEGIN`, asynchronous rollback cleanup after an early return, and caller-owned `Db::begin_transaction` lifetime. ## Relationship to #6229 #6229 is the incident-driven timeout precursor. This PR does not add or change `statement_timeout`, `lock_timeout`, `idle_in_transaction_session_timeout`, retries, audit durability, or client-visible conflicts. It provides the missing distributions needed to evaluate those policies later and intentionally leaves #6229's open audit retry/durability finding untouched. The branches overlap in `crates/buzz-db/src/lib.rs` and `crates/buzz-db/src/migration.rs`, so a later rebase may need textual conflict resolution, but the behavior is complementary rather than duplicated. ## Risk assessment Moderate-low. The primary risk is instrumentation overhead and added static series. Cardinality is source-bounded, slow logs are sampled/redacted root events, and the lock/transaction changes wrap existing awaits without changing policy or ordering. ## Verification Author workstation: `buzz-tornquist-db-pressure-observability` (`2010927`), exact head `d7cf833e26c528adfcde3917ded80daf6f4ddac9`, parent `6f50e6b2b2a996349149af61d35bdd6a355f77fd`. - `cargo fmt --all --check` — passed - `cargo clippy -p buzz-datastore-tracing -p buzz-db -p buzz-audit -p buzz-search -p buzz-relay --all-targets -- -D warnings` — passed - `cargo test -p buzz-datastore-tracing --quiet` — 4 passed - `cargo test -p buzz-db --quiet` — 109 passed, 200 ignored - `cargo test -p buzz-audit -p buzz-search --quiet` — 16 passed, 25 ignored - `cargo test -p buzz-relay --lib --quiet -- --test-threads=1` — 906 passed, 48 ignored - Native PostgreSQL focused tests for pool success/timeout/error, lock success/contention/timeout/error, replacement, membership serialization, push ordering, deletion fencing, migration/schema exclusion, and reader fallback — 8 passed The default-parallel relay run passed once; subsequent runs exposed the existing load-sensitive `api::mesh_demo::tests::demo_join_forwarded_arm_round_trips_echo` 504 at the end of the suite. That test passes in isolation and the full relay suite passes serially. Independent exact-head review workstation: `buzz-tornquist-db-pressure-observability-review` (`2013067`). Formatting, the same all-target clippy command, datastore instrumentation tests, DB unit tests, source privacy guards, and diff/non-goal audits passed; no review findings.

Logan Johnson	cc8a8b0dcb	fix: bump h2 for RUSTSEC-2026-0258 (#6222) ... 🤖 ## Summary - Bump the locked `h2` version from `0.4.14` to `0.4.16` to clear RUSTSEC-2026-0258, which affects h2 versions through `0.4.15`. - Keep the change lockfile-only; no manifest or product-code changes are included. ## Details - `h2` is now `0.4.16` with checksum `a9f37a958b41b3b19ee2707c06439c0e9e547e847223eb791ecb0cb821c65e27`. - The lockfile was regenerated by `cargo update -p h2 --precise 0.4.16` using Cargo 1.95.0 / rustc 1.95.0, matching `rust-toolchain.toml` and the CI pin. - Cargo's canonical resolver output also rewrites 16 dependency references to existing `windows-sys` package entries: - `anstyle-query 1.1.5`, `anstyle-wincon 3.0.11`, `socket2 0.6.3`, `termina 0.3.3`, and `uds_windows 1.2.1`: `0.61.2` → `0.60.2`. - `dirs-sys 0.5.0` and `nu-ansi-term 0.50.3`: `0.59.0` → `0.60.2`. - `colored 3.1.1`, `errno 0.3.14`, `quinn-udp 0.5.14`, `rustix 0.38.44`, `rustix 1.1.4`, `rustls-platform-verifier 0.7.0`, `seize 0.5.1`, `tempfile 3.27.0`, and `winapi-util 0.1.11`: `0.59.0` → `0.52.0`. - All four referenced `windows-sys` versions (`0.52.0`, `0.59.0`, `0.60.2`, and `0.61.2`) were already present in the baseline lockfile. There are zero new package entries or checksums, and the only package record replacement is `h2 0.4.14` → `0.4.16`. There is no `wasmtime` edge change. ## Validation - `cargo-deny check` passed. - `cargo build --workspace` passed. - `just test-unit` passed: 455 passed, 0 failed, 1 ignored; all nine package suites passed.

Wes	e0940927ff	fix(channels): return complete member rosters (#5765) ... ## Summary - return complete channel rosters instead of truncating at 1,000 members - chunk `event_mentions` inserts inside one transaction so large kind `39002` snapshots remain discoverable by every `p` tag - add a targeted `buzz-admin reconcile-channels --channel <uuid>` force-republish path for stale discovery snapshots - cover a 1,501-member roster, 11,000-tag mention index, and kind `39002` tag construction past member 1,000 ## Why The relay builds NIP-29 discovery and several authorization decisions from `get_members()`, but that helper silently returned only the first 1,000 active members. Desktop then counted the truncated kind `39002` event, while late members could be rejected by roster-scanning member actions. Removing the roster cap exposes PostgreSQL's 65,535 bind-parameter ceiling in mention indexing, so the insert is chunked transactionally to preserve all-or-nothing indexing. The existing reconcilers only fill missing discovery events. The targeted admin option bypasses the separately known 1,000-channel reconciliation-list ceiling and replaces an existing channel snapshot using the configured production relay key. ## Attribution This supersedes and builds on #3166 by @LordMelkor. Thank you for identifying the roster boundary and contributing the original complete-roster and mention-index patch. The production roster/query changes and the two PostgreSQL regressions retain that work's shape; this PR rebases it onto current `main`, adds relay coverage, and adds the targeted repair operation requested for rollout. ## Validation Exact pushed head: `24d02e4f3824150ed84913c9d230e675502e5b12` - `cargo check -p buzz-db -p buzz-admin` - `cargo test -p buzz-db channel::tests::get_members_returns_full_roster_beyond_1000 -- --ignored --exact --nocapture` - `cargo test -p buzz-db feed::tests::insert_mentions_indexes_rosters_past_bind_parameter_cap -- --ignored --exact --nocapture` - `cargo test -p buzz-relay --lib handlers::side_effects::tests::group_members_snapshot_keeps_members_past_one_thousand -- --exact` - `cargo run -q -p buzz-admin -- reconcile-channels --help` - mandatory pre-push hook: branch-skew, desktop checks/typecheck/tests, mobile tests, Rust tests, and desktop Tauri checks all passed on the pushed head ## Rollout 1.

Kalvin C	8a2c9af2db	feat(deletion): add durable whole-community deletion (#4425) ... ## Summary Adds a durable, operator-controlled V1 for deleting an entire Buzz community without deleting another tenant's data. The workflow is exposed through `buzz-admin deletions`: - `sweep` records independent fleet storage-taxonomy observations - `submit`, `list`, `inspect`, and `approve` manage a deletion request - `unblock` resumes a fail-closed request after an operator records remediation identity and reason - `run` and `drain` execute bounded work Requests advance through a PostgreSQL-backed state machine and stop at `retention_pending` after logical deletion has been independently verified across PostgreSQL, object storage, and Redis. This PR ships the engine and CLI, not a continuously running worker or Kubernetes packaging. For V1, a cluster/VM administrator invokes `/usr/local/bin/buzz-admin` from the existing relay image, for example with `kubectl exec` or an equivalent container/VM exec path. ## What whole-community V1 removes For the target community, V1 removes: - rows from the allowlisted community-scoped PostgreSQL catalog, including members, profiles, authored events and bodies, DMs, reactions, mentions, memberships, tokens, workflows, moderation, audit, feedback, and rate-limit state - media sidecars and upload-attribution records under `_meta/<community>/` and `_uploads/<community>/` - Git repository pointers under `repos/<community>/` - Redis keys under `buzz:<community>:*` The community row survives as a permanent tombstone, and deletion control-plane records remain as evidence of the request, approval, execution, and result. ## Safety model Deletion is not a broad `DELETE CASCADE` followed by optimistic cleanup. The destructive boundaries are durable and fail closed. ### 1. Inventory and approval - `submit` resolves the target and freezes the schema plus summary-only storage inventory. - Approval is bound to the exact request, community, and frozen inventory digest. - Unsupported manifest versions, malformed keys inside the target's owned prefixes, live scoped-table/write-fence coverage drift, frozen-inventory mismatch, and approval mismatch block execution rather than guessing. Migration and catalog revision numbers are not authorization gates; the executor validates the live safety shape instead. - Storage inventory is server-side prefix scoped to exactly: - `_meta/<community>/` - `_uploads/<community>/` - `repos/<community>/` - The deletion path never lists the whole shared bucket and has no arbitrary per-community object cap. Its listing work is proportional to the target community's bindings, not total fleet storage. - Fleet-wide taxonomy sweeps remain independent observability. They report unknown writer shapes but do not gate deletion submission, fencing, or destructive progress. Maintainers must add deletion taxonomy coverage whenever a new community-owned object-key class is introduced; writer-coverage tests bind the current media and Git writers to that contract. ### 2. Quiesce, fence, and destructive freeze - Writes continue through submission, inventory, and approval. They stop when execution moves the target into `quiescing` and then establishes the durable fence. - Already-admitted external effects finish under heartbeated serving-write leases; the exact admitted lease may renew while the community is quiescing, but new lease acquisition is rejected. The executor drains admitted leases before destructive work. - Invite minting after quiescing begins fails as typed `AccessDenied` (HTTP 503 at the relay boundary) before an invite can be persisted. - Database triggers enforce the community write fence across the complete catalog of community-scoped tables. Startup/readiness and destructive execution validate that catalog so a newly added but unfenced table cannot silently escape. - **Named isolation assumption — fresh write snapshot.** Every writer transaction that can reach a community-fenced relation must use PostgreSQL `READ COMMITTED`; each guarded write therefore observes a statement snapshot no older than acquisition of the community deletion lock. `REPEATABLE READ` and `SERIALIZABLE` can retain a pre-fence snapshot and are unsupported for writers. The writer pool refuses non-`READ COMMITTED` sessions at connection setup, and both SQL fence functions reject an explicit per-transaction isolation override with SQLSTATE `25000`. Configuration-delivered bad isolation can surface through SQLx as a pool-acquire timeout because every `after_connect` attempt is rejected; the precise `community writes require READ COMMITTED isolation` reason remains observable when the SQL guard is reached. Read-only replica transactions are outside this assumption. - Holding the shared advisory lock until the guarded write executes is a separate liveness condition: under `READ COMMITTED`, releasing it early does not permit resurrection because the trigger rechecks the fence, but it can turn a fleet sweep into a statement-wide SQLSTATE `55000` abort. - After the fence closes writers, storage is re-enumerated into chunked side-table rows. Per-prefix counts and digests bind those concrete keys to the destructive manifest. - Manifest chunk insertion, update, and deletion are protected after freeze. This closes the race where an unbound key could otherwise appear after the manifest was committed. ### 3. Checkpointed destruction - Target-owned object bindings are deleted from the frozen destructive manifest in bounded batches with durable progress. - The concrete key list lives in chunked side-table rows rather than one request-row JSON value. It supports large communities, resumable execution, and terminal cleanup. - Missing objects are accepted as idempotent crash-window outcomes; malformed ownership, changed evidence, and unexplained target-prefix drift fail closed. - PostgreSQL purging remains scoped by `community_id`, including the guarded NIP-RS hard-delete path discovered with real Desktop kind `30078` read-state data. - Redis cleanup explicitly scans and `UNLINK`s only `buzz:<community_id>:*`. Natural expiry is insufficient because some keys, including tunnel generation counters used as fencing state, are deliberately persistent. ### 4. Independent verification - PostgreSQL logical absence is checked after purge. - The three target-owned storage prefixes are freshly inventoried again and must be empty. - Redis requires two complete empty namespace scans. - Only after all three stores pass does the request advance through `logically_verified` to `retention_pending`. ## What V1 deliberately does not erase ### Shared content-addressed storage Per-community deletion removes bindings, metadata, attribution records, and Git pointers. It does **not** physically delete fleet-shared CAS bytes that another community may still reference: - media blobs and thumbnails - Git manifests, packs, and indexes (`manifests/`, `packs/`, and `idx/`) Safe reclamation requires a separate fleet-wide reachability and retention GC. Unknown keys elsewhere in the shared bucket do not block one community's deletion; malformed or unrecognized keys inside that community's three owned prefixes still fail closed. ### External retained copies The online logical-deletion proof does not erase object versions/replicas, database backups/WAL, CDN copies, provider retention copies, or observability exports. Those require their own retention and purge controls. ### Member-only erasure This PR erases a whole community. It does not implement the different operation "erase one npub while preserving the community." Removing membership or accepting NIP-09 is not member erasure. A member-only workflow would need to find and selectively remove or redact authored event content and pubkeys, profile data, DMs, reactions, mentions, memberships/roles, tokens, workflows/subscriptions, upload attribution, moderation/audit history, repository attribution, and identity embedded in tags or JSON. It would also need explicit rules for ownership transfer, surviving replies and thread metadata, audit-chain integrity, immutable Git history, and shared-CAS reachability. That requires a pubkey-level fence and selective graph rewrite; it is a separate deletion product, not a safe extension of this whole-tenant worker. ## In scope - migration `0029_community_deletion.sql`: requests, approvals, leases, manifest chunks, checkpoints, tombstones, and the universal write-fence catalog - durable executor leases, generations, heartbeats, retry/block state, and resumable stage transitions - operator-driven `sweep`, `submit`, `list`, `inspect`, `approve`, `unblock`, `run`, and `drain` commands - serving-path fences for database writes and external effects across event ingest, media, Git, workflow, push, invites, mesh/tunnel, and related paths - target-prefix-only storage inventory, summary manifests, post-fence destructive chunks, and bounded batch deletion - exact community Redis namespace purge and two-pass absence verification - cross-community isolation, crash/resume, manifest-integrity, writer-taxonomy, and schema/migration regressions - desired-state `schema/schema.sql` support without requiring a SQLx migration ledger ## Deferred / not covered - dedicated Helm/chart worker Deployment, service account, secrets, probes, resources, and network policy - autonomous `buzz-admin deletions worker` poll loop and worker-only health server - least-privilege separation among migration, relay-serving, and destructive execution roles - fleet-wide shared-CAS physical GC - backup/provider/CDN/observability retention completion - member-only erasure - provider-native conditional-delete improvements - a general force-continue escape hatch; permanent safety failures remain fail closed unless an operator remediates the cause and records an audited `unblock` The removed continuous-worker implementation remains deferred; no remote follow-up branch is claimed by this PR. ## Validation ### Current PR head and repository state Current pushed head: `359d8402ee15f049768f54156f67b953c7a7e2ed`, rebased onto `cc9a2f783375e51a6e8d1f2f9d01d5f7e22813d1` (`origin/main` at push time). The complete PR diff is now 47 files, 9,834 additions, and 517 deletions. The bespoke source-scanner stack was removed to keep this PR scoped to community deletion. Tyler/team requested the underlying fenced-write safety behavior, not `ast-grep`, `crates/buzz-db/tests/community_fenced_writes.rs`, its 27 fixtures, or the new `scripts/lints/community_*.yml` rules. Those scanner-specific files, dependencies, Hermit links, and runner wiring are absent from the current tree. The production database write fence, startup/destructive live-catalog validation, and deletion behavior remain. Source validation on this exact SHA passed: - `cargo fmt --all -- --check` - `bash -n scripts/run-tests.sh` - `cargo nextest run -p buzz-db --all-targets`: 102 passed, 173 skipped, 0 failed - `cargo nextest run -p buzz-deletion --all-targets`: 10 passed, 9 skipped, 0 failed - `cargo nextest run -p buzz-admin --all-targets`: 1 passed, 0 failed - affected-package/all-target Clippy with warnings denied - lockfile consistency - Helm 3.16.4 lint and all 44 chart unit tests - Helm region controls using that fixture: default `BUZZ_S3_REGION=us-east-1`, explicit `eu-west-2` override, and blank-region schema rejection The prior Kubernetes battery below was run against `928992237358a3294621ac0280830b77155abc04`. It remains useful evidence for the patch-equivalent production deletion implementation, but it is **not** claimed as exact-SHA evidence for current head `359d8402ee15f049768f54156f67b953c7a7e2ed`; the current cleanup removes only scanner/test/tooling infrastructure. CI restarted for the new head after the rebase and is pending. Human review remains `CHANGES_REQUESTED`. ### Prior-head live Kubernetes deletion and safety gates The full program used one immutable image, real PostgreSQL, Redis, MinIO, and a three-relay Kubernetes release: - source: `928992237358a3294621ac0280830b77155abc04` (**prior head**) - image: `buzz-e2e:sha-928992237358` - immutable image digest: `sha256:a1a204f4618ac22d9e210be5e5290645a15d79831ae30b0e44379357c8e4a895` - evidence root: `/tmp/buzz-e2e/20260807T033025Z-928992237358-full-gates/` - evidence-manifest digest: `82875c5bc9bea7370b796a7aef3457b3a1c8306c84c59e0f7388bbb5ad30e865` Passed gates at that prior head: - **Chart/operator region:** default `us-east-1`, explicit nondefault propagation, blank-region schema rejection, live in-pod environment, and an in-pod taxonomy sweep over 18 objects with zero unknown. - **Fenced writers and lifecycle:** open-write/fence ordering; 100-attempt anti-starvation; invite, push matcher, and exhausted-reaper bystander isolation; non-`READ-COMMITTED` rejection; manifest/tombstone contracts; eight-failure stage block and audited `unblock`. - **Destructive lifecycle:** submit → approve → run → `retention_pending`; PostgreSQL tombstone and Redis/S3 verification true; zero retries/errors; terminal reruns rejected with exit 5. - **Fresh 10,001-object crash boundary:** exactly two chunks (10,000 + 1). The executor deleted chunk 0 from MinIO while its PostgreSQL stamp was row-lock-blocked, was killed with `SIGKILL`, left one object and both stamps absent, then resumed the same request under generation 2 to zero objects and terminal state. - **Independent dead-owner recovery:** a dedicated executor claimed generation 1, blocked before effects, and was killed through containerd with `SIGKILL` (no TERM cleanup). The request remained owned and unreclaimable before lease expiry; a successor claimed generation 2 after 60 seconds and completed with two attempts and zero retries. - **Three-pod socket isolation:** ordinary NIP-42 and joined huddle-audio target witnesses on every replica received exact `1008 / community deleted`; healthy-tenant witnesses on those pods remained live; deleted-host reconnect returned HTTP 404. - **Health/provenance:** all replicas independently returned ready and retained the exact image digest before/after destructive runs and an audio-enabled rolling restart; PostgreSQL, Redis, and MinIO were healthy at close. Instrument corrections were retained as evidence rather than counted as product failures: a foreground PostgreSQL forward caused an initial `PoolTimedOut`; Kubernetes pod deletion exercised graceful TERM rather than dead-owner recovery; shell-background socket witnesses died with their parent; and the first image build hit the corporate TLS proxy. Detached forwarding/witnesses, containerd `SIGKILL`, and the configured internal CA/Artifactory mirror produced the discriminating runs without weakening product security. ### Prior-head cleanup For the prior-head Kubernetes run, the Helm release was removed, namespace absence was verified, run-owned Screen sessions were absent, and that source worktree remained clean. The evidence manifest was independently recomputed and every indexed artifact passed `shasum -a 256 -c`. The current `359d8402` source worktree is also clean after the scanner-only cleanup and push. --------- Signed-off-by: npub122y0pqkertljmedu303rl0aqrj3w8pvu43t6jxm6875lzg6f2pwqegc3xc <5288f082d91aff2de5bc8be23fbfa01ca2e3859cac57a91b7a3fa9f12349505c@buzz.block.builderlab.xyz> Signed-off-by: npub1dccv64krpcpse5cmkzfeh998cftungyatw3djt8jwdw6g43f7fyqzzmrf7 <6e30cd56c30e030cd31bb0939b94a7c257c9a09d5ba2d92cf2735da45629f248@buzz.block.builderlab.xyz> Signed-off-by: Kalvin Chau <kalvin@block.xyz> Signed-off-by: am <6e30cd56c30e030cd31bb0939b94a7c257c9a09d5ba2d92cf2735da45629f248@buzz.block.builderlab.xyz> Signed-off-by: cid <d9f92a72922bf45c17379a47d64dae84b6020397c2d5a52b5317d512068cd9d3@buzz.block.builderlab.xyz> Co-authored-by: npub122y0pqkertljmedu303rl0aqrj3w8pvu43t6jxm6875lzg6f2pwqegc3xc <5288f082d91aff2de5bc8be23fbfa01ca2e3859cac57a91b7a3fa9f12349505c@buzz.block.builderlab.xyz> Co-authored-by: npub1dccv64krpcpse5cmkzfeh998cftungyatw3djt8jwdw6g43f7fyqzzmrf7 <6e30cd56c30e030cd31bb0939b94a7c257c9a09d5ba2d92cf2735da45629f248@buzz.block.builderlab.xyz> Co-authored-by: cid <d9f92a72922bf45c17379a47d64dae84b6020397c2d5a52b5317d512068cd9d3@buzz.block.builderlab.xyz>	2026-08-12 09:25:58 -07:00
Will Pfleger	c966b862fe	fix(deps): bump webbrowser to 1.2.4 for RUSTSEC-2026-0257 (#5659) ... ## What Bumps `webbrowser` from `1.2.1` to `1.2.4` in both lockfiles (`Cargo.lock` and `desktop/src-tauri/Cargo.lock`) to clear [RUSTSEC-2026-0257](https://rustsec.org/advisories/RUSTSEC-2026-0257). ## Why The advisory landed in the RustSec DB and flipped the `Security` job (`cargo-deny check`) red on `main` — the same job passed on identical lockfile state before the advisory was published. `webbrowser` 1.2.1 substitutes the URL into the Unix `BROWSER` env template *before* tokenizing, allowing browser argument injection (e.g. `--remote-debugging-port`). `crates/buzz-agent` calls `webbrowser::open()` for the OAuth flow (`crates/buzz-agent/src/auth.rs`) with an internally-constructed HTTPS URL, so practical exploitability is low, but the gate is correctly blocking. Fixed in `1.2.2`+. ## Scope Lockfile-only. The `crates/buzz-agent/Cargo.toml` constraint is already `webbrowser = "1"`, so no manifest change is needed. `webbrowser` 1.2.4 pulls in `objc2-app-kit` as a new transitive dependency; the `windows-sys` edge churn re-unifies to versions already present in the lockfile (no new `windows-sys` version is introduced). ## Verification - `cargo-deny check` passes locally on the pinned toolchain (`advisories ok, bans ok, licenses ok, sources ok`); RUSTSEC-2026-0257 no longer reported in either lockfile. - `cargo check -p buzz-agent` compiles clean against `webbrowser 1.2.4`.

Dave Grochowski	397796c5f3	feat(tracing): add PostgreSQL tracing spans (#3678) ... ## Why Expose PostgreSQL datastore latency within existing request traces so slow logical database operations can be identified without recording tenant data or query arguments. ## What - Add client spans around logical PostgreSQL operations across the database facade, search, audit, replica fencing, and command persistence - Use a dedicated `buzz_datastore` target and `db.system.name = "postgresql"` for filtering and backend classification - Exclude health-check database calls and scrub raw identifiers and errors from newly traced paths ## Risk Assessment Medium — this instruments frequently used datastore paths and increases trace volume when enabled, but does not change SQL execution or datastore behavior.

Mic Neale	240cdd3ea1	chore: mesh upgrade, clean up legacy special case code, simplify model selection for mesh (#5289) ... Shared compute now has exactly two model choices: MeshLLM's virtual `mesh` model, or a model you name. Buzz picks between them in one place, and buzz-agent no longer knows meshes exist. ## What changed - **MeshLLM v0.74.0 → v0.75.1.** v0.75.0 added `degrade_to_single_model`, so a `model=mesh` request is answered by one served model when there is no committee to form, instead of failing. v0.75.1 adds Mesh-LLM#1196, which skips stale pre-0.75 runtime cache entries rather than aborting startup on them — without it, anyone who had run mesh on 0.73/0.74 could not start. - **Deleted the client-side mesh catalog probe.** buzz-agent used to poll `/v1/models` (5s TTL, 30s cooldown, two-observation debounce) to decide whether `mesh` was safe to send. MeshLLM now decides per request, so the polling, its hysteresis, and its 503 fallback are gone. - **One mapping point.** `relay_mesh_wire_model()` turns the stored value into a wire name: `auto` becomes `mesh`, a named model passes through. The spawn env, the ACP harness, and the readiness probe all use it, so they cannot disagree — previously `BUZZ_ACP_MODEL` and the probe both said `auto`, a name the mesh does not advertise. - **Removed the `nostr-relay-pool` advisory exception.** #5404 allowed RUSTSEC-2026-0243 "after mesh-llm migrates to nostr-sdk >= 0.45". v0.75.1 does, so the retired crate is gone from both lockfiles and the exception would only mask a future advisory for it. - **Deleted `scripts/ensure-mesh-native-runtime.sh`** and its six justfile call sites. It built llama.cpp from source into the runtime cache; the app already downloads the signed release runtime itself, and CI never called it. ## Why it is better **−639 lines of Rust.** Availability is decided by the node that knows the answer, per request, instead of by a client cache that could be stale for up to 30 seconds. A second worker joining now takes effect on the next request rather than after two confirming probes. ## Behaviour change A 503 on an explicit `mesh` request takes the ordinary transport retry under the same model instead of failing over to a second one — there is no second model to fail over to now. MoA repairs partial committee results internally before it reaches that point. ## Validation `crates/buzz-relay/examples/mesh_agent_e2e.rs` now sends `mesh` where it previously sent `auto` or the physical model id, so no leg was covering what Buzz actually puts on the wire. 4/4 on gemma-4-E4B, gemma-4-26B-A4B, and Qwen3-8B — including a real ACP tool call through `mesh` into buzz-dev-mcp, asserted by reading the written file back off disk. Hand-tested in the desktop app on both gemma-4 sizes: picked Auto, agent logged `model_id=mesh`, replied in channel. ## Not covered A committee that forms and then loses a worker returns 502, and that needs two workers to reproduce — not testable on one machine. --------- Signed-off-by: Michael Neale <michael.neale@gmail.com> Co-authored-by: Michael Neale <michael.neale@gmail.com>	2026-08-11 11:40:07 -04:00
Will Pfleger	5e4c05f90b	feat(desktop): NIP-AM agent-usage backend — P2 emission/transport/archive + P4a aggregation/D6 (#4000) ... ## What Implements Phases 2 and 4a of the Usage v2 plan (plan events `d0268cd0`/`0e95b035`), extending the archive backend to emit, transport, archive, and aggregate both cache categories and billing identity fail-closed. ### P2 — emission, transport, archive **Tri-state accumulators** (`Unseen`/`Exact`/`Unknown`) for cache-read and cache-write in `buzz-agent` turn and session state. Absent field = Unknown (never zero) through the full pipeline. No `unwrap_or(0)` on the cache path. Both cache folds are gated on usage-bearing responses (same gate as the total-state and identity folds) — a response with no usage at all must not poison either accumulator. **Overflow-aware input token parsing and accumulation** — closed end-to-end from parse through wire to ACP: - `sum_usage()` returns `SumUsageResult` (`Exact(u64)` | `Overflow`) — checked arithmetic, never clamps. `anthropic_input_tokens()` returns `Option<SumUsageResult>` since it sums three fields (`input_tokens + cache_read_input_tokens + cache_creation_input_tokens`) that can collectively overflow. Single-field callers (`prompt_tokens`, `completion_tokens`, etc.) convert via `.into_exact()` — their single-field sums cannot overflow. - `LlmResponse.input_tokens_overflowed: bool` propagates the parse-layer signal into the run loop. When set, `input_tokens` is `None` (clamped value discarded), the context-gate baseline (`last_request_input_tokens`) is frozen at its prior reading, and `turn_input_tokens` is poisoned to `TurnIOState::Poisoned` before any emission — including mid-turn `emit_usage_update` calls. A dedicated enum on `LlmResponse.input_tokens` would ripple into ~20 existing test assertions on `r.input_tokens == Some(...)`; the bool flag confines the change to the two call sites that check it. - `TurnIOState` (`Unseen`/`Exact`/`Poisoned`) for input and output: per-round fold uses `checked_add`; overflow poisons permanently at turn and session level, no healing. Absence does not poison (pass-2-cleared contract unchanged). Wire emission omits `accumulatedInputTokens`/`accumulatedOutputTokens` when poisoned — never null, never `u64::MAX`. ACP treats absent = publisher-poisoned: `delta_reliable: false`, null turn fields, null cumulative for that category; session cumulative stays unknown for all subsequent turns once poisoned. **Conditional wire emission** for `accumulatedCachedInputTokens` and new `accumulatedCacheWriteTokens`: fields are omitted when the cumulative is Unseen or Unknown. ACP `_goose/unstable/session/update` contract documented next to the payload with tests for all absence/zero variants. **`PricingIdentity` stamping (publisher-side)**: - `pricing_authority()`: canonical parsed-URL endpoint comparison against the official allowlist — HTTPS only, exact allowlisted host (lookalike-safe), default port (omitted or explicit :443), required API base path, rejects userinfo/query/fragment/path-prefix lookalikes. - Model: the actually-requested `request_model` after mesh/auto resolution (not `effective_model_str`). - Turn discipline: identity retained only while ALL usage in the current turn carries one identical proven identity; any mismatch, unproven-usage-bearing response, or unpaired cumulative snapshot poisons to absent; a later matching notification does not heal a mixed turn. **ACP `UsageTracker` identity fold**: per-in-flight-turn tri-state identity accumulator replacing last-update-wins. Any absent identity on a token-advancing notification or exact mismatch poisons to absent; poison survives later updates; reset in `begin_turn()`/`take()`; reset also when a request fails (baseline cleared so preflight gate cannot stay frozen sub-threshold on retries). **M3 migration**: adds `turn_cache_write_tokens`, `cumulative_cache_write_tokens`, `pricing_authority`, `pricing_model`, `pricing_cache_class` to `agent_metric_index`. Additive, idempotent, guarded per-column by marker. M2 migration also guarded per-column (turn and cumulative cache-read columns checked and added independently; marker commits only after both are present). Fresh-DB schema includes all columns. **First-turn baselines**: `seed_zero_baseline` seeds `last_input: Some(0)`, `last_output: Some(0)`, `last_cached_input: Some(0)`, `last_cache_write: Some(0)`, and `last_total: Some(0)` — all have the known-zero-at-spawn argument. Absent fields from incoming snapshots still produce unknown (tri-state unchanged). Sessions buzz-acp did not spawn (no seed) remain fail-closed on turn one. **`ReportedUsage` TS mirror**: `cacheReadTokens`, `cacheWriteTokens`, `freshInputTokens` added to `tauriArchive.ts` as `UsageField` members, field-for-field with the Rust struct. ### P4a — aggregation layer **Extended S-1 ladder** to cache-read and cache-write via the same `ladder_token` path as the existing token fields. **`freshInputTokens` derivation**: checked arithmetic, fail-closed — absent cache fields produce Unknown (not zero), overflow and `cacheRead+cacheWrite > input` both produce `incomplete: true`. Aggregated as a `UsageField`. **D6 comparator**: `sort_value()` = provider total when known, else `input+output` when both known, else `None` (unknown-last). Replaces the prior total-only comparator for both agent-level and model-level sort. Ships a pinned test vector that the TS render layer (P5) must match. ## Test coverage - `buzz-agent`: 440 lib + 15 integration (golden_transcripts) — includes 13 new `cache_total_state_tests`; 14 new `turn_io_state_tests`; 3 new `sum_usage_*` tests (exact single-field, exact two-field, overflow signals correctly); 3 new `parse_anthropic_*` tests (overflow flag set + value cleared, normal sum no flag, absent usage no flag); end-to-end golden transcript drives real subprocess with Anthropic-shaped `input_tokens: u64::MAX, cache_read: 1` response and asserts `accumulatedInputTokens` absent from the emitted `usage_update` — no logic duplication; 3 wire pin tests; 4 `fold_pricing_identity_*` tests; `pricing_authority()` explicit-:443 acceptance - `buzz-acp`: 700 tests (691 lib + 9 integration) — 4 new usage tests (absent input → unreliable+null; absent output → unreliable+null; goose-shaped both present unchanged; poison mid-session); 3 ACP behavior tests; 7 pool lifecycle tests - Desktop (Rust): 2259+ tests — 14 new P4a pinned tests; 2 M3 round-trip tests; 1 serde key-shape test; 2 M2 partial-schema migration tests; first-turn cache round-trip test ## Related PRs - P1 NIP-AM spec: [#4632](https://github.com/block/buzz/pull/4632) - P3 pricing table: [#4629](https://github.com/block/buzz/pull/4629) - UI (P5): [#4001](https://github.com/block/buzz/pull/4001) --------- Signed-off-by: Will Pfleger <pfleger.will@gmail.com> Signed-off-by: Duncan <dcfd242e557282d7a1e2cf2e6877522682f1e5c6156dc92ca7d90eaedd3b0f95@buzz.block.builderlab.xyz> Co-authored-by: npub1mn7jgtj4w2pd0g0zeuhxsa6jy6p0rewxz4kujt98my82ahfmp72sxjexk7 <dcfd242e557282d7a1e2cf2e6877522682f1e5c6156dc92ca7d90eaedd3b0f95@buzz.block.builderlab.xyz>	2026-08-10 10:47:37 -04:00
