e5736b8ff0 fix(buzz-auth): close SSRF/redirect bypass in HttpJwksFetcher; trim internal markers
- Remove with_client() bypass: HttpJwksFetcher is now a unit struct;
  each fetch_jwks call builds a dedicated per-request pinned client.
- Add resolve_and_check_ssrf: DNS-resolves host:port via spawn_blocking,
  rejects any resolved private/reserved IP (closes DNS-rebinding TOCTOU).
- Per-request client enforces: redirect(Policy::none()), no_proxy(),
  .resolve(host, pinned_ip), and timeout(JWKS_REQUEST_TIMEOUT_SECS).
- Drop unused client field (dead_code warning) now that no shared pool
  is needed.
- Remove pure-paraphrase doc on IssuerRegistry::all_policies(); replace
  with doc stating constraint (unspecified order, startup use).
- Remove all 'PR N' internal markers from doc comments; replace with
  production-stable references to the jwks runtime.

e78bafab69 fix(auth): harden JWKS boundary, reject current-status, fix generation and comment quality
HTTP boundary (finding 1):
- Add validate_jwks_uri(): HTTPS-only, no credentials/fragments, bare IP
  private-address rejection via buzz_core::network::is_private_ip
- HttpJwksFetcher::new() builds a hardened client: no redirects, 10s intrinsic
  deadline; with_client() documents caller invariants
- Stream response body incrementally (bytes_stream + StreamExt), stop at
  MAX_JWKS_RESPONSE_BYTES + 1 before any deserialization
- Reject non-2xx status before reading body
- Add reqwest 'stream' feature to workspace; add futures-util to buzz-auth deps
- Add MAX_JWKS_TIMING_SECONDS = 1 year upper bound on timing fields
- Regression tests: non-HTTPS, loopback/private IP, credentials, fragment,
  oversized timing, duplicate issuer all rejected at construction

CurrentStatus posture (finding 2):
- Rename error variant DuplicateIssuer(String) -> DuplicateIssuer (sanitized)
- Add UnsupportedPosture error variant
- validate_nip_fi_config() rejects any CurrentStatus policy with
  UnsupportedPosture — verifier has no status witness; startup fails closed
- discovery.rs: remove FreshnessClassDiscovery::CurrentStatus variant and
  FederatedIdentityDiscovery::current_status() constructor entirely
- Test asserts rejection both with and without JWKS config

Duplicate issuer detection (finding 3):
- validate_nip_fi_config(): explicit duplicate detection in JWKS config slice
  (collect() was silently overwriting); returns DuplicateIssuer on collision
- ProductionJwksSource::new(): rejects duplicate issuer via HashMap::contains_key
  before insert

Timing bounds and overflow (finding 4):
- MAX_JWKS_TIMING_SECONDS constant bounds both refresh and hard-deadline fields
- i64::try_from() + Duration::try_seconds() eliminates u64->i64 cast panic
- Validated at both ProductionJwksSource::new() and validate_nip_fi_config()
- Test: new_rejects_timing_above_maximum()

Generation monotonicity (finding 5):
- Replace wall-clock millis with SHA-256 content digest per issuer
- Generation counter advances (saturating_add) only when digest changes;
  identical documents preserve the prior generation
- Regressions: generation_stable_for_identical_document(),
  generation_advances_for_changed_document()

Clippy (finding 6):
- manual_async_fn: replaced RPITIT form with native 'async fn' in impl block
- single_match (startup): replaced match { None => .., Some(_) => {} } with
  if let / !contains_key
- unnecessary_get_then_check: replaced .get().is_none() with !contains_key()

Comment quality (all files):
- Remove module-to-PR table from nip_fi/mod.rs
- Remove all 'Phase A', 'PR 1/3', 'PRs 4-5' references from every doc comment
- Remove WHAT comments (field-name paraphrases, narrated steps, section
  banners with no contract content, 'Construct with a default reqwest client')
- Retain WHY: security invariants, exact NIP-FI spec refs, fail-closed choices,
  FI-TRACE/FI-INV stable identifiers

5d7cf011b2 feat(auth): NIP-FI Phase A PR 3 — production assertion runtime
Add the JWKS discovery/caching layer, startup validation gate, and
NIP-11 discovery output that complete the NIP-FI assertion runtime.

The verifier (PRs 1–2) already defined the sealed IssuerKeySource trait
and AssertionKeySet constructor as placeholders for this PR. This PR
fills that contract with a production implementation:

- jwks: ProductionJwksSource<F> implements IssuerKeySource via an
  injectable JwksFetcher trait (sealed; HttpJwksFetcher for production).
  Bounded periodic refresh; coalesced in-flight; try_read/try_lock for
  async-safe synchronous key_set() path. Never serves an expired
  snapshot; fails closed on fetch/parse error. [FI-TRACE-JWKS-REMOVE]

- startup: validate_nip_fi_config() rejects incomplete or unsafe
  configurations before the relay accepts protected traffic: empty
  registry, unmatched JWKS configs, invalid timing bounds, and
  current-status issuers missing a JWKS source. Off/DenyProtected modes
  accept without validation. [FI-INV-14, FI-INV-15]

- discovery: FederatedIdentityDiscovery serializes the NIP-11
  federated_identity object. Never exposes enrollment mode, issuer
  URLs, audiences, or deployment-local identifiers.
  [FI-TRACE-DISCOVERY-PRIVATE]

- config: IssuerRegistry gains all_policies() iterator.
- verifier: sealed module promoted to pub(crate) for jwks access;
  AssertionKeySet::new #[allow(dead_code)] removed (now has real caller).

Security checklist:
- Issuer binding sealed at constructor: no relabelling possible
- Hard deadline enforced on every snapshot access
- MAX_JWKS_RESPONSE_BYTES checked before parse
- Key count bounded by MAX_JWKS_KEYS
- try_read/try_lock: fails closed rather than panicking or blocking
- No key material, issuer URLs, or token bytes in errors or Debug

Tests: 23 new unit tests (12 JWKS, 11 startup); all green.

bd851f85e7 test(buzz-db): isolate event-side trigger and add applied lifecycle fixture
Two MINOR accuracy gaps from Thufir Pass 2:

1. Event-side trigger isolation
   The denied-receipt-then-event negative in
   denied_lifecycle_receipt_commits_without_audit_event queues both
   deferred triggers in one transaction; it does not prove the event-side
   trigger (authorization_event_receipt_cardinality) alone. Add
   denied_lifecycle_receipt_event_side_trigger_isolated: commit a denied
   receipt in auto-commit (no deferred trigger active), then open a new
   transaction that inserts only the mapped success-transition event and
   asserts COMMIT rejection with the exact constraint name. Rejection
   must come from the event-side trigger only.

2. Applied lifecycle coverage at migration 42
   No test exercised the outcome_code IN (1, 3) branch at migration 42.
   Add applied_lifecycle_receipt_requires_exactly_one_event: an applied
   enroll receipt + exactly one mapped event commits; the same setup
   without the event rejects with
   authorization_operation_receipt_event_cardinality. Uses the minimum
   valid circular identity/lifecycle setup (policy + history + receipt +
   binding + event), stops at migration 42 not 41.

3. Correct surrounding mutation/coverage comments
   - denied_lifecycle_receipt_commits_without_audit_event: update
     mutation note to name both new tests, remove the stale claim that
     the receipt-then-event negative covers both trigger directions.
   - The receipt-then-event negative comment is tightened to say only
     the receipt-side trigger fires in that transaction.

No production SQL changes. All 11 NIP-FI ignored PostgreSQL regressions
green (--test-threads=1).

156ced4167 fix(schema): enforce zero mapped-success events for denied lifecycle receipts
A denied core lifecycle receipt (outcome_code = 2) requires zero events
of the mapped success-transition kind. The previous blanket RETURN NULL
for outcome_code NOT IN (1, 3) let a denied receipt commit alongside its
mapped success-transition event, creating contradictory durable ledger
facts: denial plus enrolled/retired/revoked/rotated.

Replace the early return with a three-way branch in
authorization_operation_receipt_event_guard_v1():

  outcome_code IN (1, 3) — exactly-one mapped event (unchanged)
  outcome_code = 2       — zero events of the mapped transition kind;
                           raises authorization_denied_lifecycle_receipt_no_success_event
  other                  — skip (not a core lifecycle outcome)

Both deferred trigger directions share the same function body; a single
transaction with both INSERT paths exercises both directions at COMMIT.
The new negative fixture inserts a denied enroll receipt plus its mapped
success-transition event (event_kind = 1) in one transaction and asserts
COMMIT rejection with the exact constraint name.

Mutation: stashing the ELSIF branch lets COMMIT succeed, so expect_err
panics — confirming the branch is load-bearing (verified red).

Also correct three stale doc comments:
- Remove the "COMMIT succeeds" claim in the attempt-side shape guard
  mutation note; accurately state the pre-existing semantic-binding
  constraint fires instead.
- Remove the false claim that denial-attempt/admission-result tests
  protect applied/no-op lifecycle; replace with accurate coverage note.
- Update the semantic_fingerprint column comment to distinguish
  unresolved pre-auth kind-9 (actor_kind = 4) from authenticated kind-9
  (actor_kind 1-3).

All changes byte-mirrored between migration 0042 and schema/schema.sql.
All 9 NIP-FI ignored PostgreSQL regressions pass (--test-threads=1).

3c2c919dab fix(schema): correct NIP-FI authorization shape/cardinality contracts and add regressions
Addresses all five Kalvin-agent findings against PR 2 head 0534277b4:

**Authenticated kind-9 shape (IMPORTANT):** The semantic_fingerprint CHECK
and denial-attempt cardinality guard incorrectly classified every kind-9
event as unresolved pre-auth, requiring a denial-attempt row and a non-null
fingerprint for authenticated OperatorDenied events (actor_kind 1–3). Scope
the non-zero semantic_fingerprint constraint to actor_kind = 4 (require NULL
for actor_kind 1–3). On the event side, skip the denial-attempt guard when
actor_kind ≠ 4. On the attempt side, add a shape guard that rejects binding
to any event with actor_kind ≠ 4 or non-null request_fingerprint, named
authorization_denial_attempt_event_kind so the attribution is distinguishable
from the pre-existing semantic-binding check.

**Lifecycle receipt outcome cardinality (IMPORTANT):** The lifecycle-event
guard fired for denied lifecycle receipts (outcome_code = 2), requiring a
fabricated transition event. Apply event cardinality only for outcome_code
IN (1, 3), matching the stated successful/no-op contract. A denied receipt
now commits without a paired audit event.

**Stale migration-number comments (MINOR):** Three comments in 0042 still
referenced migration 0040 after the identity migration was renumbered to
0041. Updated to 0041.

**Trailing EOF blank (MINOR):** Removed extra blank line at end of
schema/schema.sql; git diff --check is now clean.

**CI wiring:** Excluded per Will's ruling — Luke owns the PostgreSQL CI lane.

New regressions added to migration.rs (both #[ignore = "requires Postgres"]):
- authenticated_kind_9_denial_commits_without_denial_attempt: positive A
  commits an authenticated denial without a denial-attempt row; negative B
  proves a denial-attempt cannot attach to the authenticated event, assertion
  keyed on exact constraint name authorization_denial_attempt_event_kind.
- denied_lifecycle_receipt_commits_without_audit_event: a denied enroll
  receipt commits standalone; guard skips outcome_code 2.

Mutations verified red:
1. Removing actor_kind gate from event-side trigger → positive A fails
   (COMMIT rejected, no attempt row present).
2. Removing actor_kind shape guard from attempt-side → negative B fails
   with authorization_denial_attempt_semantic_binding instead of
   authorization_denial_attempt_event_kind.
3. Removing outcome_code NOT IN (1, 3) gate → denied-receipt positive fails.

All 9 NIP-FI PostgreSQL regressions pass at the corrected head.
Mirror: every changed function/check applied identically to schema/schema.sql.

fc309e67d2 test(buzz-db): replace barrier race with controlled lock-wait-observation schedule
The previous concurrency regression used a tokio::sync::Barrier to
synchronize two connections before racing to INSERT the same revision.
That construction synchronizes client-side INSERT dispatch, not trigger
execution; a lock-free schedule where one INSERT completes and commits
before the other reads MAX still satisfies the XOR + 23514 assertions,
so the test offered no deterministic proof that pg_advisory_xact_lock
is required.

Replace with a controlled two-connection schedule:

  1. tx1 opens a transaction and inserts revision 102. The BEFORE INSERT
     trigger acquires pg_advisory_xact_lock and completes; tx1 holds the
     advisory lock until commit.
  2. tx2 opens a transaction on a second backend, reports its pg_backend_pid
     over a oneshot channel, then issues INSERT for revision 103. The
     trigger fires and blocks on the advisory lock held by tx1.
  3. The main task polls pg_stat_activity WHERE pid = tx2_pid AND
     wait_event_type = 'Lock' AND wait_event = 'advisory' with a 10 s
     bounded timeout. Without pg_advisory_xact_lock in the guard the
     trigger returns immediately, tx2 never enters the advisory wait, and
     the poll times out — making the regression deterministically red.
  4. tx1 commits, releasing the lock. tx2 unblocks, its trigger reads the
     fresh MAX=102, and INSERT 103 succeeds. tx2 commits.
  5. Final count asserts six revisions (1, 2, 100, 101, 102, 103).

Zero production changes: migrations/0041, migrations/0042, and
schema/schema.sql are byte-untouched (single-file diff confirmed).

fd2a79bdba fix(schema): address Thufir pass 2 blockers on NIP-FI PR 2
Three IMPORTANT findings addressed:

IMPORTANT 1 (denial semantic binding, partial): Bind the remaining two
unbound denial identity coordinates.

- Add semantic_fingerprint BYTEA to authorization_events: required non-zero
  for kind-9 events, NULL for all other event kinds (enforced by CHECK
  on the table). This is the redaction-safe intent_digest coordinate.
- Add authorization_denial_reason_reason_code_binding CHECK to
  authorization_authentication_denial_attempts: encodes the canonical
  OperatorAuthenticationDenialReason <-> AuthorizationReasonCode mapping
  from operator_lifecycle.rs:700-706 and authorization_events.rs:215-226:
  MissingCredential(1)<->Missing(2), InvalidCredential(2)<->Invalid(3),
  Unauthenticated(3)<->Unauthenticated(4). Fires at INSERT, not COMMIT.
- Extend authorization_denial_attempt_guard_v1() to compare
  semantic_fingerprint between event and denial attempt in both firing
  directions, raising 23514 'authorization_denial_attempt_semantic_binding'
  on mismatch. Carl's mismatched-reason and mismatched-fingerprint
  cross-attachments are now fully closed.

IMPORTANT 2 (concurrency regression): Replace the 10ms-sleep approach
with a tokio::sync::Barrier(2) that holds both connections after BEGIN
and before INSERT. Both race to pg_advisory_xact_lock; one blocks, the
winner commits, the loser sees MAX=102 and fails with 23514 (not 23505).
XOR assertion proves exactly one INSERT succeeds, and the loser's 23514
(not PK 23505) proves the advisory lock — not just PK uniqueness — is the
serialization mechanism. Contradictory comments fixed.

MINORs (folded in):
- Fix stale test doc comment claiming effective_at must advance (it does
  not; the downstream constructor stamps Unix epoch for immediate policy).
- Fix equal-revision comment incorrectly claiming different policy_digest
  avoids the PK; the PK is (community_id, policy_revision).

CI fmt failure: cargo fmt --all run; whitespace-only reformatting of
some query blocks in migration.rs.

Regressions added/updated:
- B4: denial_reason/reason_code mapping violation rejected at INSERT by
  the immediate CHECK (23514 from authorization_denial_reason_reason_code_binding).
- B5: semantic_fingerprint mismatch between event and denial attempt
  rejected at COMMIT by the deferred guard (23514 from
  authorization_denial_attempt_semantic_binding).

Byte-parity (extraction+cmp):
- authorization_events table: 3394 bytes, migration == schema.sql
- authorization_authentication_denial_attempts table: 2062 bytes, migration == schema.sql
- authorization_denial_attempt_guard_v1(): 5579 bytes, migration == schema.sql
- identity_enrollment_policy_revision_guard_v1(): 1113 bytes, migration == schema.sql
- authorization_admission_result_guard_v1(): 2164 bytes, migration == schema.sql

All five NIP-FI tests green locally (run in isolation to avoid pre-existing
pool-state flakiness in the full suite).

5ba7d2614c fix(schema): address Thufir pass 1 blockers on NIP-FI PR 2
Three IMPORTANT findings fixed:

1. Drop effective_at monotonicity from policy revision guard
   identity_enrollment_policy_revision_guard_v1() now enforces only
   strict-greater policy_revision per community. The effective_at check
   had no NIP-FI basis (FI-INV-06 defines assertion_policy_id stability,
   not revision chronology) and would reject legitimately-sequenced
   revisions — the downstream constructor stamps every immediately-
   effective revision with Unix epoch, so revision 2 would fail after
   revision 1 under the old guard.

2. Bind semantic coordinates in denial attempt guard
   authorization_authentication_denial_attempts gains attempt_id UUID
   NOT NULL with a deferred FK to authorization_events on
   (community_id, operation_id, event_kind, attempt_id). The guard
   authorization_denial_attempt_guard_v1() now additionally compares
   correlation_id and reason_code between the event and its denial
   attempt row, raising check_violation (23514) with named constraint
   authorization_denial_attempt_semantic_binding on mismatch. This
   closes the Carl finding 3 gap: a kind-9 event for correlation A /
   reason X can no longer be paired with a denial row carrying
   correlation B / reason Y.

3. Rewrite regression tests to prove the contracts
   - Policy test: seeds a gap (100->101) then inserts unused revision 99
     and asserts 23514 from the named guard (not 23505, which would
     fire on a PK duplicate and not prove the monotonic comparison).
     Adds a two-transaction concurrency regression: two distinct forward
     revisions (102, 103) race through separate connections; both commit
     because the advisory lock serializes them and each is valid.
   - Denial test: replaces the ambiguous negative-B (23503 OR 23514)
     with three single-coordinate-mismatch cases attributed to the named
     guard: B1 correlation_id mismatch (23514), B2 reason_code mismatch
     (23514), B3 attempt_id mismatch (23503 via deferred FK).
   - Admission test: adds negative C -- mismatched request_fingerprint
     rejected by the immediate composite FK (23503) at INSERT, proving
     the coordinate binding half of Carl finding 2.

All four changed files byte-identical between migration files and
schema/schema.sql (verified by extraction+cmp). All 5 NIP-FI tests,
admin_schema_parity, and 2 unit tests pass.

152c5070b5 fix(buzz-db): add NIP-FI Carl r2 guards — policy monotonicity, admission result cardinality, denial attempt binding
Finding 1 (policy revision monotonicity): add
identity_enrollment_policy_revision_guard_v1() BEFORE INSERT on
identity_enrollment_policies. Uses a per-community advisory lock via
hashtextextended so concurrent writers serialize the max-revision read,
then asserts both policy_revision and effective_at strictly exceed the
current community maximum (FI-INV-06 — stable assertion policy).

Finding 2 (admission result ↔ kind-11 receipt cardinality): add
authorization_admission_result_guard_v1(), bidirectional deferred
constraint trigger on both authorization_operation_receipts (kind-11
receipt must have exactly one result) and authorization_admission_results
(result must attach to a kind-11 receipt). Mirrors the pattern of the
existing authorization_operation_receipt_event_guard_v1.

Finding 3 (denial event ↔ attempt binding): add
authorization_denial_attempt_guard_v1(), bidirectional deferred
constraint trigger on both authorization_events (kind-9 event must have
exactly one denial attempt) and
authorization_authentication_denial_attempts (attempt must reference an
existing kind-9 event). The existing FK binds (audit_event_kind=9) but
does not require a kind-9 event to have a matching attempt row; this
guard closes that gap.

All three fixes applied identically in migrations/0041, migrations/0042,
and schema/schema.sql; the parity assertion continues to pass.

Tests added (all three mutation-sensitive, two-sided):
- identity_enrollment_policy_revision_is_monotonic
- authorization_admission_result_requires_kind_11_receipt_bidirectional
- authorization_denial_attempt_requires_kind_9_event_bidirectional

No new tables; fence exclusion list unchanged; #[ignore] deletion suite
need not rerun.

a83d29e2c5 test(buzz-db): add absent-policy FK rejection to provenance regression
Extends identity_binding_provenance_is_independent_of_enrollment_mode with
the negative half required for two-sided mutation sensitivity.

A second deferred transaction inserts an otherwise-valid identity_bindings
row referencing policy_revision 999 (nonexistent in
identity_enrollment_policies) and asserts the INSERT fails with SQLSTATE
23503 from the narrowed FK identity_bindings(community_id, policy_revision)
→ identity_enrollment_policies(community_id, policy_revision).

Non-vacuity verified: removing the FK from the migration causes the
absent-policy INSERT to succeed (rows_affected: 1) and the expect_err
assertion to fire, confirming the negative half detects a dropped or
neutered FK. The existing positive half catches the old composite FK;
together they give full two-sided coverage.

Zero production changes: migrations 0040/0041 and schema.sql are
byte-untouched.

315740d672 fix(buzz-db): narrow identity_bindings policy FK and add provenance regression
The FK on identity_bindings previously equated binding_provenance with the
enrollment policy's enrollment_mode via a composite reference:
  (community_id, policy_revision, binding_provenance)
    → identity_enrollment_policies (community_id, policy_revision, enrollment_mode)

This contract-breaks NIP-FI §352 and §424: provenance is determined from
operation evidence, not the policy mode. A TOFU-mode policy (mode=3) with an
attested-key binding (provenance=1) — a valid and specified admission path —
would fail at commit with a FK violation.

Narrow the FK to (community_id, policy_revision) → (community_id,
policy_revision), which is already the PK of identity_enrollment_policies.
The redundant UNIQUE (community_id, policy_revision, enrollment_mode) on
identity_enrollment_policies is removed; it existed only to satisfy the old
composite FK and has no other consumer.

Both changes applied in lockstep to the migration and the schema.sql mirror.
The parity assertion in admin_schema_parity_between_desired_state_and_migrations
continues to hold.

Add behavioral regression identity_binding_provenance_is_independent_of_enrollment_mode:
seeds a TOFU-mode policy, inserts an attested-key binding in a single deferred
transaction, and asserts the commit succeeds with provenance=1 and mode=3
persisted independently. Mutation-verified: restoring the composite FK causes
the test to fail with the exact FK violation (code 23503) the fix removes.

738655da08 fix(buzz-db): drop stale relationship_revision_floor from invalidation guard
The authorization_invalidation_floor_guard_v1 trigger compared
NEW/OLD.relationship_revision_floor, but authorization_invalidation_floors
has no such column — a later FI-DELEG field correctly trimmed from the
Phase-A table when mining, yet left in the guard body. PL/pgSQL defers
record-field resolution, so the function CREATEs and all catalog/parity
tests pass, but the first real monotonic floor advancement aborts with
'record NEW has no field relationship_revision_floor', making the floor
update path unusable.

Remove both comparisons from the migration and its byte-matched schema.sql
mirror, and add a behavioral regression test that advances a floor through
the live trigger (forward generation and binding_version_floor commit;
equal/regressive updates reject) — coverage a deferred PL/pgSQL failure
structurally evades in catalog tests.

bafdff958a feat(db): add NIP-FI identity + final-admission schema foundation
Introduce the Phase-A NIP-FI schema as two internally-ordered migrations:
0040 lays down the core identity and base-lifecycle relations, and 0041
applies to 0040's resulting state to add the final-admission surface
(replay/receipt, audit events, invalidation, capacity, protected-object
authority, restore version deltas, and the closed admission result).

Identity is issuer-qualified (iss, sub) with no hardcoded issuer. All 15
NIP-FI relations are a durable, immutable, append-only security ledger:
both migrations widen the single SQL source of truth
community_write_fence_excluded_table so the relations are never
fence-attached, purged on community deletion, nor counted as tenant-scoped
drift by the deletion control plane's exact-set catalog check — the same
posture as product_feedback and rate_limit_violations. schema.sql keeps one
consolidated definition of that function whose body byte-matches 0041.

f463e726dd fix: retrieving cold memories; add regression task (#6950)
## Why

Evaluating buzz agent memory retrieval by seeding a memory then asking
the buzz agent a question it needs that memory.

**Bug Found**: System prompt had no inclusion of retrieving cold
memories and suggested looking in a mem/*.md directory that does not
exist. Updated `system-prompt.md` to include memory CLI tools and usage.

Eval Before System Prompt Change: 0/3 
Eval After System Prompt Change: 3/3 

## What

- Add a `memory-retrieval` benchmark that seeds agent memory with `buzz
mem set` before asking a direct question.
- Grade the observable threaded answer without inspecting tool calls or
exposing the answer in channel history.
- Teach agents to use `buzz mem set`, `buzz mem ls`, and `buzz mem get`
for cold memory.
- Add a wire-debug endpoint configuration for diagnosing ACP tool calls
in local runs.
- Add fixture, seeding, verifier, and prompt coverage.

## Risk Assessment

Low. The runtime changes are limited to the benchmark harness. The
production-facing change clarifies existing memory commands in the base
prompt; it does not change memory storage, relay behavior, or
authorization.

## References

- Before the system-prompt changes, 0/3 attempts passed because agents
never invoked the `buzz mem` CLI and instead searched a non existent
filesystem
- After the changes, 3/3 attempts passed. ACP wire logs confirmed that
every agent ran `buzz mem ls` followed by `buzz mem get` and returned
`net_gpv`.

e47690c21b Enforce NIP-OA authorization time bounds (#7004)
NIP-OA relay admission now evaluates signed `created_at<` and
`created_at>` conditions against the already verified authentication
event timestamp. An owner-signed credential such as `created_at<1` no
longer upgrades its holder to relay membership.

The verified timestamp now flows from NIP-42, NIP-98, and Blossom
authentication through the shared membership gate used by WebSocket,
HTTP, Git, media, huddles, GIF, and workflow requests. Owner-attested
access fails closed when no signed authentication timestamp is
available. Direct relay members keep their existing admission behavior,
and `kind=` remains connection-level metadata as specified by NIP-AA.

Tests cover strict time-bound evaluation, missing timestamp rejection,
and HTTP authentication timestamp propagation.

Testing:

- `cargo test -p buzz-sdk nip_oa::tests -- --nocapture`
- `cargo test -p buzz-relay api::relay_members::tests -- --nocapture`
- `cargo test -p buzz-relay api::bridge::tests -- --nocapture`

3ed623bb21 feat(db): configurable writer session timeouts (lock, idle-txn, statement) (#6229)
## Why

A wedged relay boot pod holding a relation lock can park every other
writer in the fleet behind it: DB load pins at pool capacity in
`Lock:relation` waits while CPU stays flat, and nothing server-side
releases the lock until the holder dies. We hit exactly this in
production — ~1,400 sessions queued behind one crash-looping pod's boot
transaction for ~20 minutes until kubelet killed the container.

## What

Applies session-level Postgres timeouts to every **writer** connection
inside the existing single `after_connect` hook in `buzz-db`, all
env-tunable through the same `Config::from_env → DbConfig` path as the
existing pool-size knobs:

| Env var | GUC | Default | Effect |
|---|---|---|---|
| `BUZZ_DB_LOCK_TIMEOUT_MS` | `lock_timeout` | 5000 | statements waiting
on any lock fail fast instead of parking behind a wedged holder |
| `BUZZ_DB_IDLE_TXN_TIMEOUT_MS` | `idle_in_transaction_session_timeout`
| 60000 | reaps wedged clients idling inside an open transaction while
holding locks |
| `BUZZ_DB_STATEMENT_TIMEOUT_MS` | `statement_timeout` | 0 (off) |
opt-in runaway-statement cap; off by default because startup
migrations/backfills legitimately run long statements |

`0` disables a timeout (Postgres semantics) and deliberately passes
through the env parsing — unlike the pool-size knobs where `0` falls
back to the default. The reader pool is untouched: replica sessions
never take contended locks and already fail acquire in 150 ms.

Deployers tune these via plain env vars (`.env`, or `relay.extraEnv` in
the Helm chart) — no code changes needed.

## Behavior change to note

With the 5 s default `lock_timeout`, a boot-time migration or backfill
that waits >5 s on a lock now errors (surfacing in logs / crash-looping
the pod) instead of stalling silently. That is the intended
visible-failure-over-fleet-stall tradeoff; deployers with slow contended
migrations can set `BUZZ_DB_LOCK_TIMEOUT_MS=0`.

## Testing

- `cargo test -p buzz-db -p buzz-relay` — buzz-db green; buzz-relay has
9 failures that also fail on clean `main` in this environment
(api::admin/api::media/mesh_demo — unrelated, pre-existing).
- New config test covers override / `0`-passthrough / invalid-fallback
for all three env vars.
- Extended the existing `writer_pool_safety_hook_is_single_and_composed`
source-shape test so the timeouts can't drift out of the single
`after_connect` hook (SQLx replaces hooks — a second hook would silently
disarm the floor guard).
- `cargo fmt --check` and `cargo clippy --all-targets` clean for the
touched crates.

Closest existing PR/issue: none found.

---
**Update Aug 28, 17:06 EDT:** Rebased onto `main` at `a3730784fc` and
addressed the latest correctness review.

- Ported the timeout policy onto the refactored `buzz-db::runtime` pool
constructor and kept the shared env overlay for relay, admin, deletion,
and audit writers.
- Migration/schema-destruction connections now disable `lock_timeout`
and `statement_timeout` for their intentional long wait/DDL path. This
supersedes the earlier “Behavior change to note”: contended boot
migrations wait for the current migration owner rather than
crash-looping after five seconds.
- The audit worker now preserves and retries the same entry on
PostgreSQL `55P03` lock timeouts, using exponential backoff capped at
one second. Other database errors retain the existing terminal error
behavior, and retries emit `buzz_audit_log_lock_retries_total`.
- Added CI-backed PostgreSQL regressions for writer GUC
installation/migration exemption, audit-pool lock timeouts, and worker
recovery. The worker regression holds the real audit advisory lock past
`lock_timeout`, observes a retry, releases the lock, and proves the
original entry is appended exactly once.

Current verification supersedes the earlier testing notes: workspace
Rust clippy passed with warnings denied; all nine infrastructure-free
backend unit-test lanes passed; all three focused PostgreSQL regressions
passed against PostgreSQL 17; formatting, diff checks, file-size guards,
and desktop frontend checks passed. The Linux Blox workstation could not
run the unrelated Tauri native lane because `glib-2.0` is absent, so
that platform check is left to PR CI.


---
**Update Aug 31, 11:09 EDT:** Rebased onto current `main` at
`c3132c3ee9` and reran the requested audit-lock contention scenario on
Blox at head `896c3fe9ed`.

- `git range-diff` reports both PR commits unchanged by the rebase; the
branch remains two commits and the worktree is clean.
- `cargo fmt --all -- --check` and clippy with warnings denied passed
for `buzz-db`, `buzz-relay`, `buzz-admin`, and `buzz-deletion`.
- All three focused PostgreSQL 17 regressions passed: writer session
timeout/migration exemption, audit writer timeout bounds, and audit
worker recovery of the original entry exactly once.
- Live protocol verification used a head-built relay and CLI, native
PostgreSQL 17/Redis, `BUZZ_DB_LOCK_TIMEOUT_MS=300`, and an eight-second
hold on the community audit advisory lock. The real message was accepted
and persisted once while the lock was held; its audit-row count remained
zero during contention while retries accumulated. After release, exactly
one `event_created` audit row appeared and remained exactly one after an
additional two-second duplicate check. The run recorded nine
lock-timeout retries, zero audit failures, and event ID
`7f8c4ffae28e78555fcf2d56396d6e6c01b3712e5411288dc79e9a54af9d9444`.

eed74bde2f feat(buzz-agent): surface stop reason and silent-turn WARN in telemetry (#7038)
## What

Two telemetry additions to make a known silent-death failure mode
visible in harness logs.

**1. `stop` field on `llm: call completed` INFO**
(`crates/buzz-agent/src/llm.rs`)

The `ProviderStop` value was already parsed and stored on `LlmResponse`
but never emitted in the log line. Without it, "model chose `end_turn`"
vs "gateway truncated/refused" is indistinguishable from telemetry
alone.

**2. WARN on silent-turn signature** (`crates/buzz-agent/src/agent.rs`)

Emits a `WARN` when a turn produces no publish, no visible assistant
text, and either near-zero or absent output tokens. The WARN logic is
extracted into `warn_if_silent_turn` (pure synchronous function) so the
seam is testable without the async run loop.

Three independent gates before the WARN fires:
1. **`!buzz_reply_call_seen`** — no publish attempt in any round,
tracked unconditionally via the existing `is_buzz_reply_call` matcher.
Read-only tool calls do NOT suppress the WARN; a turn that ran tools but
never published and died at 3 tokens is still a silent death.
2. **`text_is_empty`** — no visible assistant text in the final round. A
terse reply like "OK" (≤12 tokens, non-empty) is not a silent death.
3. **Token check** — two distinct WARN messages:
- `Some(t) where t <= 12`: near-zero token count, the observed failure
signature (2–12 tokens)
- `None` usage: provider omitted token counts entirely, separately
diagnostic

Tests use a scoped `tracing_subscriber` layer (same pattern as the
existing stall-warn tests in `llm.rs`) to exercise the WARN seam
directly:
- Canonical signature (no publish, no text, 4 tokens) → 1 WARN
- Non-empty assistant text → 0 WARNs
- Publish seen → 0 WARNs
- `None` usage (no publish, no text) → 1 WARN

## Why

Recurring silent-death incident in a specific agent×channel combination:
sessions die with 1 LLM call, 2–12 output tokens, no tool calls, no
message, no error — recorded as a "successful" turn. The harness log
shows the token count but not the `stop_reason`, leaving the root cause
undiagnosable without request-level tracing. The observed shape also
includes tool-step-then-3-token-death (one tool call, then silence) —
the publish-aware gate catches both shapes.

Context thread:
buzz://message?channel=91fd9ca1-cf04-4ef7-b18f-aa2aee55692b&id=e3f1693f2e29f26a0c840f8054d592270c1504beacdc1d9c2063d8ab82960a06

## Scope

Logging and telemetry only. No behavior change, no retry-logic change,
no stop-reason mapping change.

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`:

    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.

a3730784fc refactor(db): extract domain stores from database runtime (#6987)
## Summary

Finish the remaining database-store extraction tracked by
[TheSentinel454/buzz#2](https://github.com/TheSentinel454/buzz/issues/2)
in one reviewable PR.

This consolidates the previously stacked domain slices after #6782
merged. It preserves the runtime/store boundary established by #6660,
#6668, #6700, and #6782 while separating database runtime infrastructure
from domain-owned persistence:

- `runtime/` owns pool construction and sizing, writer/reader routing,
read sessions and route proofs, transaction infrastructure,
observability primitives, replica fencing, health support, migrations,
and cross-cutting runtime tests.
- `store/` owns domain records, SQL, row parsing, locks and invariants,
`Db` domain methods, focused tests, and logical-operation datastore
spans.
- `lib.rs` remains a 57-line compatibility facade that preserves
existing crate-root paths and `Db` method signatures through re-exports.

Domain coverage includes API tokens, authentication allowlists,
reminders, event queries, threads, reactions, feeds, users and DMs,
push, workflows/runs/approvals, relay membership and invites, product
feedback, moderation/admin moderation, relay admin actions/operators,
git repositories, archived identities, usage, partition maintenance,
deletion, channel membership inherited from merged #6782, and the final
runtime/store layout.

The branch has been rebased onto current `main`. Database changes that
landed there were incorporated rather than overwritten:
`relay_admin_actions.rs` and `relay_operators.rs` now live under
`store/`, their 27 public `Db` wrappers and existing behavior remain
intact, and every wrapper has exactly one fixed-name datastore span.
Concurrent changes to migration, moderation, admin moderation, and error
handling are also retained.

This supersedes #6783, #6784, #6787, #6788, #6789, #6792, #6820, #6794,
#6796, #6797, #6798, #6799, #6804, #6805, #6806, #6808, #6809, #6811,
#6812, #6813, #6814, #6815, and #6890. Their discussions remain
available for review history.

### #17 / #19 acceptance

- Preserves the metric names, fixed labels, transaction/lock timing
boundaries, and privacy/cardinality constraints introduced by #6700.
- Keeps exactly one datastore span per public logical operation,
including the 27 relay-admin wrappers added on `main`.
- Removes `store_ownership.rs`; physical ownership and focused source
guards now enforce the boundary directly.
- Leaves no `impl Db`, domain SQL, focused domain test group, or
datastore span in `lib.rs`.
- Preserves existing public paths such as `buzz_db::channel`,
`buzz_db::event`, and `buzz_db::workflow` through crate-root re-exports
while keeping internal `runtime` and `store` namespaces private.

### Non-goals

- No SQL, schema, locking, transaction, retry, timeout, or
client-visible behavior changes.
- No generic store traits, domain handles, broad `PgExecutor` migration,
new store crate, raw pool accessor, or broader directory reorganization.
- No tracker issues are closed by this PR.

### Risk

The cumulative diff is large but structural. Risk is primarily
module-path, ownership, or conflict-resolution drift. It is mitigated by
preserving public re-exports, comparing the newly moved `main`
implementations to their upstream source, source guards, touched-crate
compilation, PostgreSQL-backed test coverage, and an independent
exact-head review on a separate clean Blox workstation.

### Testing

86b9142a09 refactor(relay): NIP-98 admin auth with Operator/Moderator roles and NIP-11 discovery (#3777)
Adds authenticated, role-based moderation to the relay admin API. On
`main` the admin API is read-only and gated only by `Host`/`Origin`
matching; this branch adds NIP-98 authentication, a two-tier
Operator/Moderator principal model, mutation and staffing endpoints, and
NIP-11 auto-discovery so clients never type the admin URL by hand.

## Authentication (`BUZZ_ADMIN_AUTH`)

`BUZZ_ADMIN_AUTH` accepts `nip98` or `disabled`. Leaving it unset
defaults to `nip98` (fail-secure). Configuration fails closed: any other
value aborts startup, while a lingering `BUZZ_ADMIN_TOKEN` is ignored
with a startup warning — token (bearer) authentication is not supported.
`Host`/`Origin` matching is retained in every mode as defense-in-depth.

- **`nip98`** (default) — per-request signed NIP-98 (kind 27235) events,
resolved to an Operator or Moderator principal with per-person
attribution and individual revocability. Read-write per resolved
principal.
- **`disabled`** — no credential; relies entirely on network-layer
controls (reverse proxy, VPN, firewall) and logs a `WARN` on every boot.
Always read-only: `authorize()` resolves no principal, so mutation and
staffing routes always `403`.

## Roles

Buzz has two independent authority axes after this change.
**Relay-level** roles (new here) are deployment-global: they act across
every community on the relay, through the admin API. **Community-level**
roles (pre-existing, unchanged by this PR) are tenant-scoped: they act
inside one community, through signed Nostr moderation commands.

### Relay level (new)

| Role | Description |
|---|---|
| **Operator** | Full control of the deployment's moderation surface:
read all reports, feedback, and attachments across every community;
resolve reports with enforcement (`delete`/`kick`/`ban`/`timeout`) or
decisions (`dismiss`/`escalate`); reopen and cancel; update feedback
status; and manage the Operator/Moderator roster via the staffing
endpoints. |
| **Moderator** | Day-to-day triage: everything an Operator can do
except staffing — cannot view or change the roster. |

How a pubkey acquires a relay role (resolution order; config always
outranks DB):

1. Listed in `RELAY_OPERATOR_PUBKEYS` → **Operator** (source `config`)
2. Equals `RELAY_OWNER_PUBKEY` while `RELAY_OPERATOR_PUBKEYS` is empty →
**Operator** (source `owner_fallback`, a break-glass grant for
self-hosters that deactivates once any operator is configured)
3. Row in the `relay_operators` table → **Operator** or **Moderator**
(source `db`, managed via the staffing endpoints)
4. No match → `403`

### Community level (pre-existing, unchanged)

| Role | Description |
|---|---|
| **Owner** (community) | Full authority within their community: every
moderation action (delete, kick, ban/unban, timeout/untimeout, resolve
reports, view queue) plus member, role, and invite management. No guard
rails. |
| **Admin** (community) | Same community-wide moderation capabilities as
owner, except an admin cannot ban or time out the owner or a fellow
admin — only the owner may action an admin. Manages members and invites;
only the owner grants the admin role. |
| **Member** (community) | Standard participant; no moderation
capability. |
| **Owner / Admin** (channel) | Channel-local authority only: delete
messages and kick users within their own channel. |
| **Member / Guest / Bot** (channel) | No moderation authority. |

There is no community-level Moderator tier in v1; relay-level Moderator
is the only role by that name.

## Escalation scoping

The operator report queue is an escalation backstop, not the community's
day-to-day triage surface (per `VISION_MODERATION`, the severe class is
the platform's to review rather than the community's). Two rules enforce
that:

- **Escalated-by-default listing.** `GET /reports` with no `status`
parameter returns only `escalated` reports. An explicit
`status=<open|resolved|dismissed|escalated>` filter is always honored as
given, and full visibility across every status stays available for
platform-safety and legal review via `scope=all` (which lists reports
regardless of status). `scope` accepts only `all` and is ignored when an
explicit `status` is present.
- **Auto-escalated `illegal` reports.** Member reports whose category is
`illegal` are ingested with `status=escalated` rather than `open`, so
the severe class reaches the operator backstop without waiting for a
community admin to forward it. Every other category still lands `open`.
Auto-escalation only sets the queue status — it records no moderator
decision and stamps no resolver, so an auto-escalated report is
indistinguishable downstream from an admin-escalated one: the reopen
route returns it to `open` on the same terms, keyed only on status,
never on how the report became escalated.

## Principal resolution and NIP-98 admission

`resolve_admin_principal()` returns `AdminPrincipal { pubkey, role,
source }` per the resolution order above; `None` never falls through as
a role. Admission is ordered so the replay guard is a privilege, not a
public surface: signature/URL/method/payload-hash verification first,
roster check second, and only then is the deployment-scoped replay id
atomically consumed — a validly-signing but unrostered key never
allocates a replay slot. Redis failure fails closed.

## Report resolution, recovery, and enforcement provenance

`POST /reports/{id}/resolve` is a crash-safe enforcement state machine:
decision-only outcomes (`dismiss`/`escalate`) are a single
CAS-plus-audit transaction; enforcement
(`delete`/`kick`/`ban`/`timeout`) claims the report
(`open`→`processing`), runs the durable mutation, then finalizes — a
re-drive resumes at the step marker and converges to exactly-one
enforcement, fenced by a lease and an outbox claim token.

Person-directed enforcement on an `event`-kind report derives its target
from the stored event's author (server-owned truth, never the reporter's
`p` tag) via a single `derive_enforcement_target` shared by the HTTP
driver and the recovery worker. If the reported event was purged before
its author could be read, person-directed actions are rejected pre-claim
and the report stays `open`; `delete` needs only the event id and is
exempt.

`GET /reports/{id}` and the resolve response carry an `activeAction`
field surfacing the enforcement that actually executed — a report
dismissed after a reopen still reports the ban that ran. `POST
/reports/{id}/reopen` returns a terminal report to `open` (idempotent on
`requestId`). `POST /reports/{id}/cancel` is the sole recovery path for
a pre-mutation `failed` action, attributed via
`relay_admin_actions.cancelled_by`.

## Feedback

`GET /feedback` and `/feedback/{id}` survive a tenant purge: provenance
columns are severed to `NULL` rather than cascade-deleted, and the
attachment path fails closed to `404` on a severed row. `PATCH
/feedback/{id}` updates lifecycle `status`
(`new`/`reviewed`/`archived`).

## Staffing and probe

`GET/PUT/DELETE /operators/{pubkey}` are Operator-only; mutating a
config-backed pubkey returns `409 Conflict`. `GET /operators` returns
the union of config and DB principals with per-entry `source`. `GET
/probe` reports auth mode, role, source, `canAct`, and `canStaff` for
the desktop console.

## NIP-11 auto-discovery

The NIP-11 relay-information document gains an optional `admin_api`
field carrying the canonical admin origin (`scheme://host[:port]`, no
path), present iff `BUZZ_ADMIN_HOST` is set and omitted otherwise. The
scheme follows the same loopback rule as NIP-98 `u`-tag verification via
a shared `scheme_for_host` helper, so the advertised origin and the
origin the relay verifies against can never diverge.

## Operator API origin decoupling

`RELAY_OPERATOR_API_ORIGIN` is no longer required at boot when
`RELAY_OPERATOR_PUBKEYS` is set — it is used only by the
community-provisioning endpoints, which fail closed at request time
(with a boot-time `WARN`) until it is set. The admin console needs no
origin.

## Admin-web adaptation

The standalone `admin-web` dashboard signs each request as a NIP-98
event via a NIP-07 browser extension, discovers the auth mode with a
single unauthenticated probe (`200` → `disabled`, anything else →
`nip98`, fail-secure), and carries no token entry surface. Playwright
coverage exercises the NIP-98 and CSP paths.

## Security hardening

Three findings from security review are folded in:

- **Append-only roster audit.** `PUT`/`DELETE /operators/{pubkey}`
mutate the deployment-wide root of trust, but the upsert overwrites
`role`/`added_by` in place and the delete removes the only row — so a
grant→revoke sequence left no trace of who was ever granted or by whom.
Each mutation now writes an `relay_operator_audit` row (actor, target,
`grant`/`revoke`, pre-image `prev_role`, `new_role`, timestamp) inside
the same transaction as the mutation. A per-target transaction-scoped
advisory lock serializes concurrent mutations of the same pubkey before
the pre-image read, so the recorded `prev_role` is always the true
predecessor even under a concurrent-grant race. Chronology is keyed on a
`BIGINT GENERATED ALWAYS AS IDENTITY` `seq` column, not the wall clock:
the serializing lock guarantees insertion order and `seq` captures it,
so ordered reads (`ORDER BY seq`) follow the true privilege chain even
across a backward NTP step that a `clock_timestamp()` ordering would
invert. `created_at` (`clock_timestamp()`) is retained as informational
occurrence time only. Append-only by construction — no `UPDATE`/`DELETE`
path and no API surface. A no-op delete writes nothing.
- **`expirationSecs` overflow.** The timeout path built `Utc::now() +
Duration::seconds(secs as i64)` from an attacker-controlled `u64`:
`i64::MAX` panicked the handler, and a wrapped-negative magnitude minted
a *past* expiry that still passed validation. `compute_timeout_until`
now rejects zero, rejects magnitudes above a documented
`MAX_TIMEOUT_SECS` (365 days), and uses checked
`try_seconds`/`checked_add_signed` so no input can panic or produce a
past expiry — over-cap, zero, `i64::MAX`, and wrapping-negative inputs
all return a clean `4xx`.
- **Uppercase-hex config-backed bypass.** Config pubkeys are lowercased
at parse, but the `409` immutability check raw-string-compared the path
param while `decode_hex_pubkey` accepted uppercase — so `PUT
/operators/{UPPERCASE}` skipped the guard and wrote a shadow row for the
same 32 bytes. The validated param is now canonicalized (lowercased)
before the `409` check, DB write, `DELETE`, and response body.

## Migrations

- `0035_relay_operators.sql` — `relay_operators` roster table
(deployment-global), `actor_authority` on `moderation_actions`,
`processing` status plus `active_action_id` on `moderation_reports`,
`status` on `product_feedback`.
- `0036_relay_admin_actions.sql` — enforcement-action table with a
`request_id` idempotency key, a `step_marker` for crash recovery, and a
`cancelled_by` attribution column.
- `0037_relay_admin_action_lease.sql` — lease fencing for the action
worker.
- `0038_relay_admin_outbox_claim_token.sql` — fenced claim token on the
outbox worker.
- `0039_relay_operator_audit.sql` — append-only `relay_operator_audit`
trail for roster mutations (see Security hardening).

`docs/admin/README.md` documents the full principal model, NIP-98 event
requirements, capabilities by role, the startup error matrix, and the
discovery field.

## Production blast radius

A relay without `BUZZ_ADMIN_HOST` is completely unaffected — the admin
surface stays disabled and `BUZZ_ADMIN_AUTH` is ignored; a lingering
`BUZZ_ADMIN_TOKEN` logs a startup warning and must be removed. Where
`BUZZ_ADMIN_HOST` **is** set, unset `BUZZ_ADMIN_AUTH` defaults to
`nip98` (per-person signed auth); `BUZZ_ADMIN_AUTH=disabled` reproduces
`main`'s prior `Host`/`Origin`-only gating but is read-only (mutation
routes `403`). The five migrations add tables and columns without
touching existing data.

e76c81968b refactor(db): split channel membership store (#6782)
## Current reconstructed head

Exact base: `codex/issue-7-roster-test-fixtures` at
`5df440c411be9705eb29a57f0c41f7239767e007`
Exact head: `codex/issue-7-channel-membership-store` at
`8ad0782ee311f5f51b714494ce750c5937f127cc`

This current head removes `crates/buzz-db/tests/store_ownership.rs`; no
replacement path-sensitive ownership test is introduced. Apart from
removing that complete test-file diff, the production patch is
byte-for-byte identical to the previously reviewed slice. This remains
part of tracker #2 and the #17/#19 acceptance work.

Independent exact-head review from a separate clean Blox workstation
found no issues. Current-head evidence passed formatting, strict
`buzz-db` clippy, 111 non-PostgreSQL library tests with 200 PostgreSQL
tests ignored, the observability source test, relay consumer
compilation, exact ownership/unique-span review checks, and 3 channel
and 19 membership PostgreSQL tests on native PostgreSQL where
applicable.

## Why
Complete the channel ownership slice of [tracker
#2](https://github.com/TheSentinel454/buzz/issues/2) and [domain issue
#7](https://github.com/TheSentinel454/buzz/issues/7) while preserving
the runtime/store boundary established by #6660 and #6668. This child
stacks on the test-only fixture prerequisite #6819 above #6777 and
carries forward PR #6700's membership/replacement lock timing without
changing lock or transaction behavior.

## What
- Keep channel lifecycle, metadata, TTL advisory locking, and lifecycle
tests in `channel.rs`
- Move membership/roster records, SQL, advisory-lock helpers, `Db`
methods, focused tests, and datastore spans to a dedicated
`channel_members.rs`
- Preserve existing `buzz_db::channel::*` paths with compatibility
re-exports while exposing the dedicated module
- Move the four roster-fence PostgreSQL tests out of `lib.rs`

## Stack
- Exact base: codex/issue-7-roster-test-fixtures at
21d1b265c133292e6707e766cd4204e6a43f08af

- Domain: https://github.com/TheSentinel454/buzz/issues/7
- Test/span acceptance: https://github.com/TheSentinel454/buzz/issues/17
and https://github.com/TheSentinel454/buzz/issues/19

## Non-goals
- No SQL, schema, retry, timeout, lock ordering, transaction boundary,
or client-visible behavior changes
- No change to channel TTL lifecycle ownership merely because lifecycle
bootstrap writes an owner membership row
- No store traits, domain-handle redesign, broad `PgExecutor` migration,
raw pool accessor, new crate, or directory-wide reorganization
- No changes to, retargeting of, or merge action on PR #6700 or #6777

## Risk Assessment
Moderate review surface, low semantic risk. The file split is large, but
method signatures, SQL, bind order, membership and replacement lock
namespaces, transaction boundaries, and span names remain unchanged.
Compatibility re-exports preserve existing `buzz_db::channel::*`
consumers.

## Blox Verification
Author workstation: `buzz-tornquist-issue-2-store-stack` (`2046520`),
exact head `8376e19d0da3ec77550590cd91cc3dfe284d95d6`.

- `cargo fmt --all --check` — passed
- `cargo clippy -p buzz-db -p buzz-relay --all-targets -- -D warnings` —
passed
- Native PostgreSQL channel lifecycle suite — 3 passed
- Native PostgreSQL membership/roster suite — 17 passed; two
pre-existing ignored-test fixture failures reproduced identically on the
untouched parent `2de5444`:
`large_roster_reconciliation_candidates_respect_snapshot_count_and_signer`
and `locked_member_snapshot_blocks_post_capture_membership_mutation`
both receive the migration-0032 `23514` invalid-`p`-tag rejection. This
extraction intentionally does not fold a test-behavior fix into the
move.
- `cargo test -p buzz-relay --lib -- --test-threads=1` — 908 passed, 48
ignored; the existing load-sensitive mesh demo test returned 504,
matching the #6700/parent baseline
- `cargo test -p buzz-relay --lib
api::mesh_demo::tests::demo_join_forwarded_arm_round_trips_echo --
--exact --test-threads=1` — passed

Independent exact-head review: `buzz-tornquist-pr-6782-review`
(`2048397`) found no remaining critical, important, or minor issues. The
full implementation review also independently reproduced both stated
PostgreSQL fixture failures on the exact parent and passed the relay
library suite (909 passed, 48 ignored).

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.

Dependencies: none.

ae0ecd9a67 feat(model-capabilities): humanize Databricks UC model families (#6955)
Chat-eligible Unity Catalog models from the Gemini, DeepSeek, GLM, Grok,
Llama, Qwen, Gemma, and Inkling families were rendering as raw FQNs such
as `system.ai.gemini-3-5-flash` in the agent model picker. #6918
surfaces these models, but the capability manifest carried no records
for most of them and the registry-label path could not strip their Unity
Catalog or `goose-` prefixes.

I added a display-only `label_family_tokens` list and `databricks_v2`
exact records for the sixteen previously unlabeled endpoint stems. All
26 target FQNs and their `goose-` aliases now resolve to curated labels
through `databricks_registry_label`, while capability resolution
continues to use only the existing `family_tokens` (`claude-`, `gpt-`,
and `kimi-`). This keeps label discovery from changing capability
profiles for unrelated model IDs.

Each new record includes reconciliation metadata against the pinned
[models.dev catalog](https://models.dev/api.json). Nine records adopt
first-party effort evidence that the Databricks MLflow Chat transport
can express: Gemini 3.5 Flash, Gemini 3.5 Flash Lite, Gemini 3.6 Flash,
Gemini 3 Pro Image, DeepSeek V4 Flash, DeepSeek V4 Pro, GLM-5.3 Flash,
Grok 4.6, and Inkling. The remaining seven deliberately retain the
`databricks_v2/concrete_unknown` fallback because upstream evidence is
absent, identifies a non-reasoning model, or provides only
toggle/token-budget controls that `reasoning_effort` cannot represent.

The normative corpus adds the sixteen exact records, four Unity Catalog
alias probes, and two capability-isolation probes. Existing base vectors
remain unchanged, and Rust and TypeScript consume the same strict
manifest and corpus.

be8d7756d5 feat(agent): discover Databricks Unity Catalog models (#6918)
## Summary

Add Unity Catalog model-service discovery to `buzz-agent` Databricks v2,
preserve full Unity Catalog FQNs through ACP model discovery, route
model services through MLflow chat, and add the optional
`DATABRICKS_MODEL_FILTER` visibility filter.

The resilience follow-up bounds each catalog attempt across headers,
bounded body reads, and JSON parsing; retries transient 499/5xx,
transport/body failures, malformed JSON, and attempt timeouts; and emits
only safe catalog/status diagnostics.


## Validation

The live validation and test gates below were run on the pre-rewrite tip
`1cf6c66e7c5bf9a00c357bda24df48e3beeb310b`. The rewritten tip
`0364cf44f3eb5cfbd5771b0a0dd7868ce0ad2c19` has identical trees for both
commits, so the attribution rewrite changes no tested code.

- 31 catalog tests passed
- 19 Databricks OAuth/routing integration tests passed
- `cargo check -p buzz-agent` passed
- `cargo clippy -p buzz-agent --all-targets -- -D warnings` passed
- `cargo fmt --check` passed
- `git diff --check` passed
- Desktop Tauri validation passed through the repository-supported setup
path, including 2,777 library tests and auxiliary terminal suites

The full `buzz-agent` package has one separately reproduced pre-existing
failure: `regressions::cancel_kills_inflight_tool_via_mcp_notification`,
failing on both baseline `eb8e97cfe` and the follow-up worktree. No
Databricks path reaches that test. The live validation proves discovery
and ACP exposure, not inference against every listed model.

57216c942f test(db): use canonical channel roster fixtures (#6819)
## Summary

Fix two PostgreSQL channel-roster test fixtures so they satisfy
migration 0032's canonical kind-39002 fence before the
channel/membership store extraction moves them.

This is a test-only prerequisite in the issue #2 extraction stack. It
emits the canonical four-field `p` tags with authoritative roles, keeps
the stale-history mutation after insertion, and gives the colliding
other-tenant fixture its own matching roster.

## Stack

- Exact base: codex/issue-6-finish-replaceable-store at
da018405cc
([#6777](https://github.com/block/buzz/pull/6777))
- Exact head: codex/issue-7-roster-test-fixtures at
21d1b265c133292e6707e766cd4204e6a43f08af
- Structural tracker: TheSentinel454/buzz#2
- Domain issue: TheSentinel454/buzz#7
- Acceptance: TheSentinel454/buzz#17 and TheSentinel454/buzz#19
- Next: `codex/issue-7-channel-membership-store`

## Why separate

The existing ignored tests are red against a freshly migrated current
`main`: migration 0032 rejects their legacy two-field roster tags before
the assertions run. The extraction PR is intended to be a pure move, so
this fixture correction is isolated here rather than mixed into the
channel-membership ownership diff.

## Non-goals

- No production Rust or SQL changes.
- No schema, lock, transaction, timeout, retry, API, or client-visible
behavior changes.
- No change to migration 0032's canonical roster rules.
- No store ownership movement; that remains in the child PR.

## Risk

Low and test-only. The main risk is accidentally changing the scenario
rather than only its representation. The tests retain the same member
counts, stale-versus-complete distinction, tenant collision, signer
isolation, and lock-freshness assertions.

## Blox verification

Author workstation: `buzz-tornquist-issue-2-store-stack` (`2046520`),
native PostgreSQL 17.11.

- Red before the change on a freshly migrated database: both focused
tests failed with migration 0032's `kind 39002 roster contains an
invalid p tag` constraint.
- `cargo fmt --all --check`: pass
- `git diff --check`: pass

69096c9a8d preserve channel description paragraph breaks (#6946)
**Category:** fix
**User Impact:** Channel descriptions now keep their paragraph structure
everywhere people and agents read them.

**Problem:** Multi-paragraph channel descriptions were flattened in the
desktop interface and in agent context, making operational instructions
harder to scan and potentially changing their meaning. A running agent
harness could also continue using a stale description after someone
edited it.

**Solution:** Preserve authored line and paragraph breaks across the
desktop surfaces, and render descriptions as bounded, indented
agent-context blocks with semantic delimiters escaped. Prompt-visible
channel metadata now refreshes before each turn with cached fallback,
while one shared desktop derivation keeps the header and channel intro
consistent.

<details>
<summary>File changes</summary>

**crates/buzz-acp/src/pool.rs**
Refresh prompt-visible kind-39000 metadata with one bounded request per
turn so edits reach running harnesses, while retaining cached metadata
as a degradation fallback. Add regression coverage for description edits
and update request-count fixtures for the refresh lifecycle.

**crates/buzz-acp/src/prompt_framing.rs**
Add semantic text escaping for untrusted values embedded inside paired
prompt sections.

**crates/buzz-acp/src/queue.rs**
Render multi-paragraph descriptions as indented context blocks, preserve
blank lines, retain the 500-character limit, and escape semantic
delimiters. Add helper- and full-prompt tests for paragraph
preservation, UTF-8-safe truncation, and adversarial input.

**desktop/src/features/channels/lib/channelDescription.ts**
Introduce one shared channel-detail derivation and preserve newlines
between status context and authored detail text.

**desktop/src/features/channels/lib/channelDescription.test.mjs**
Cover shared field precedence, multiline descriptions, status-prefix
separation, and fallback behavior.

**desktop/src/features/channels/ui/ChannelPane.helpers.ts**
Use the shared channel-detail derivation for the channel intro instead
of maintaining a second field order.

**desktop/src/features/channels/ui/ChannelPane.helpers.test.mjs**
Verify description text wins consistently over legacy purpose text when
both are present.

**desktop/src/features/channels/ui/ChannelManagementSheetRows.tsx**
Preserve paragraph whitespace in editable and read-only channel
summaries and allow enough lines for compact multi-paragraph
descriptions.

**desktop/src/features/channels/ui/ChannelManagementSheetRows.test.mjs**
Render both channel-summary variants and assert the multiline whitespace
and four-line clamp contract.

**desktop/src/features/messages/ui/ChannelIntroBlock.tsx**
Display description line and paragraph breaks in the empty-channel
intro.

**desktop/src/features/messages/ui/ChannelIntroBlock.test.mjs**
Add render-level coverage for the intro's multiline whitespace contract.

</details>

## Reproduction steps

1. Run the desktop app and create an empty channel.
2. Give it a description with two paragraphs, including a blank line and
a multi-line second paragraph, then save and reopen channel management.
3. Confirm the empty-channel intro preserves the blank line and
subsequent line breaks.
4. Confirm the channel-management summary shows the paragraph structure
for both an editor and a read-only member rather than a detached
ellipsis.
5. Hover the channel title and confirm its tooltip keeps the
description's line breaks.
6. Add an agent, send one prompt, edit the description, then send
another prompt. Confirm the next generated agent context contains the
updated description as an indented multiline block.

## Screenshot

A real-app screenshot of the multiline channel intro and
channel-management summary is attached in the PR comments below.

Closes AIDA-1980.

0808ab485c fix(cli): enrich template cardinality error with per-candidate presence and profile hints (#4825)
## Problem

`buzz channels create --template` fails with a bare-pubkey
duplicate-instance error when a persona has more than one live instance.
When duplicate instances share the same display name and avatar, the
error gives the operator no signal to identify which instance is stale.

## What changed

**`crates/buzz-cli/src/commands/channels.rs`** (boundary) + one
visibility line in **`crates/buzz-cli/src/commands/users.rs`** (`fn
presence_subject` → `pub(crate)`), plus a relay behavior change in
**`crates/buzz-relay/src/api/bridge.rs`** and a supporting test in
**`crates/buzz-pubsub/src/presence.rs`**.

### Relay: presence-lookup failure is now surfaced as a failure

`synthesize_presence` previously collapsed a Redis `get_presence_bulk`
error into `unwrap_or_default()` → HTTP 200 `[]`, making a backend
outage indistinguishable from an authoritative all-offline snapshot. It
now returns `Option<Result<Vec<Value>, (StatusCode, Json<Value>)>>`:
`None` means the request is not a presence query (fall through),
`Some(Ok)` is a real snapshot (an empty vec is an authoritative
all-offline result), and `Some(Err)` is a backend failure surfaced as a
non-2xx response. The event tag-parse and sign paths were converted from
`.ok()?` fall-throughs to explicit `Some(Err(...))` for the same reason
— a silent fall-through would have reintroduced the fake-empty-success
anti-pattern. The function takes `pubsub` and `relay_keypair` directly
rather than the whole `AppState`, which keeps the Redis-error seam
unit-testable without live infrastructure; its single production caller
was updated accordingly, and no other caller consumes
`synthesize_presence`.

### Hint fetch architecture

**`assemble_roster_resolution<F, Fut>`** — post-fetch stage extracted
from `build_roster_resolution` as an injectable-fetcher async generic.
It contains: archive-filter-based duplicate detection, the conditional
`fetch_hints` call, and `finalize_roster_resolution` delegation.
Accepting the fetcher as a closure makes the wiring directly testable
without a relay.

`build_roster_resolution` reduces to: gather slugs → `tokio::join!(scan,
archive)` → delegate with the real `fetch_candidate_hints` closure.

**Zero hint queries on the happy path**: `assemble_roster_resolution`
only invokes the fetcher when duplicate live instances exist after
archive filtering. Untrusted archive snapshot (`Err`) conservatively
treats all found instances as live.

When duplicates exist, `fetch_candidate_hints` runs the presence
(kind:40902) and profile (kind:0) queries concurrently, bounding **each
independently** through `join_bounded_queries`: a per-query 3-second
timeout maps to `Err`, so a lookup that completes is never discarded
because its sibling hung. On total failure or timeout, bare pubkeys are
printed promptly.

### Trusted-snapshot boundary — `hints_from_results`

The relay drops the Redis presence key when an identity goes offline, so
the bulk presence snapshot never returns an event for an offline
instance — precisely the stale duplicate an operator needs flagged.
`hints_from_results` therefore treats a *trusted* presence snapshot as a
**complete snapshot** for the requested pubkeys: it seeds all of them
`offline`, then overlays returned statuses.

A response is trusted only when `trusted_presence_snapshot` validates
**every** array element as the actual snapshot contract: each must parse
as a complete signed `nostr::Event` of the presence-update kind carrying
exactly one `p` tag whose subject is one of the requested pubkeys.
Requiring the *sole* `p`-tag subject — the exact value `build_hint_map`
later reads via `presence_subject` — is what stops a mixed-tag event
(`[["p","<unrequested>"],["p","<requested>"]]`) from passing the gate
yet overlaying a different subject downstream. Any element that is not
such an event — a vacuous object like
`{"pubkey":"…","content":"online"}`, `[{}]`, `[null]`, an event of the
wrong kind, one for an unrequested subject, or one carrying more than
one `p` tag — makes presence enrichment untrusted: nothing is seeded
`offline`, so absence is never falsely inferred as offline. A failed,
timed-out, or non-array presence response is likewise untrusted. In
every untrusted case the successful profile sibling still contributes
its hints.

### Response-to-map conversion — `build_hint_map`

Sync production function taking the offline seed plus raw
presence/profile event slices. Relay-signed presence events carry the
agent pubkey in the `p` tag (not the event author); `build_hint_map`
calls `presence_subject` from `users.rs` (now `pub(crate)`) to resolve
the correct key.

### Hint display — `format_candidate`

Appends `[online/offline, profile updated YYYY-MM-DD]` (or subset) to
each candidate pubkey in the error. `profile_updated_at` names the field
correctly: kind:0 is replaceable state that desktop republishes on
rename and profile reconciliation, so `created_at` reflects the last
profile update, not provisioning time. Date formatted via
`chrono::DateTime::from_timestamp`; out-of-range timestamps omit the
date. Missing entries fall back to bare pubkeys.

### Cardinality rule

`apply_cardinality_rule` remains pure and relay-free; zero/one/many
semantics unchanged.

0ccf934b88 fix(db): disable heartbeat vacuum truncation (#6898)
## Why
`replica_heartbeat` is updated continuously, but autovacuum heap
truncation can take an `ACCESS EXCLUSIVE` lock whose replay cancels
concurrent hot-standby reads. Truncating a fixed, single-row table
provides no meaningful space benefit.

## What
- Add migration 0034 to set `vacuum_truncate = false` on
`replica_heartbeat`
- Keep the desired-state schema aligned for fresh installations
- Extend migration coverage so both paths retain the reloption

## Risk Assessment
Low — this disables only autovacuum's heap-truncation phase for a
single-row table; normal vacuum cleanup remains enabled. The tradeoff is
retaining at most the table's otherwise-truncatable tail pages.

**Update Aug 27, 2026:** Hardened fresh `pgschema` bootstraps after
review.

- Renamed the shared post-apply script to
`reconcile-schema-after-pgschema.sql` and made it restore the heartbeat
reloption and singleton row idempotently.
- Added live catalog and row assertions that stop bootstrap when the
database does not match the required state.
- Updated every repository `pgschema apply` caller, including the
desktop release smoke path.
- Added a regression test that requires future `pgschema apply` callers
to run reconciliation.
- Documented the `pgschema` DML and storage-parameter limitation in
`AGENTS.md` and at the reconciliation entry point.
- Merged current `main` and renumbered this migration to 0034 after
`main` added migration 0033.

b3baa56ba8 fix(db): exclude kind:30179 ciphertext from brownfield FTS (#6822)
## Problem

Kind `30179` (NIP-PMA private managed agent — NIP-44 ciphertext carrying
the agent nsec, env vars, prompt) joined `AUTHOR_ONLY_KINDS` in #4593,
but only **fresh** installs stopped indexing it:

- `migrations/0008` installs the positive FTS allowlist only when
`events` is empty;
- `migrations/0014` wraps the retained brownfield expression for `30350`
alone;
- `schema/schema.sql` still carries the legacy negative skip-set without
`30179`.

So a relay upgraded in place keeps tokenizing `30179` ciphertext into
`events.search_tsv`. Found by Wren while reviewing #4999 (which
activates publication of 30179 from Desktop). No readable leak: `/query`
applies `search_hit_accepted` + `event_visible_to_reader` before
serialization and live foreign searches against builderlab returned `[]`
— this is the storage-layer privacy invariant (`docs/nips/NIP-PMA.md`
deployment step 2) plus wasted FTS work.

## Fix

- `migrations/0033_private_managed_agent_fts.sql` — same shape as 0014:
capture the current generated expression via `pg_get_expr`, drop/re-add
`search_tsv` wrapped with `kind = 30179 → NULL`. Every other kind keeps
whatever policy the database already had (fresh allowlist or brownfield
skip-set). Rebuilds the GIN index; no heap-wide policy rewrite.
- `schema/schema.sql` — add `30179` to the desired-state skip-set.

## Tests

- `populated_upgrade_preserves_search_policy_except_for_private_kinds`
(renamed from `…_push_leases`): provisions the **legacy negative
expression** (migrations 1–7), inserts kind 1 / 30179 / 30350 rows,
checkpoints after 0014 (30179 still searchable, 30350 not), then runs to
head and asserts 30179 is NULL. **Proven red** with the 0033 file
removed: `left: [(1, Some(true)), (30179, Some(true)), (30350, None)]`.
- `embedded_migrator_contains_consolidated_initial_schema`: count 32→33,
asserts 0033 shape and `schema.sql` parity.
- `buzz-search/tests/fts_integration.rs` setup applies 0033 so the FTS
tripwires run against the real chain.

## Verification (HEAD 6154cc33d, same shell)

- `cargo test -p buzz-db -- --include-ignored --test-threads=1`: 305
passed / 3 failed — the 3
(`create_community_with_owner_enforces_per_owner_limit`,
`insert_mentions_indexes_rosters_past_bind_parameter_cap`,
`transfer_ownership_returns_limit_reached_for_maxed_transferee`) fail
identically on pristine `main` f24971033 with a fresh DB; unrelated to
this diff.
- `cargo test -p buzz-search -- --include-ignored`: 19 passed (incl.
`author_only_kinds_are_storage_level_unsearchable`,
`p_gated_persistent_kinds_have_storage_null_tsvector`).
- `desired_state_schema_bootstrap_progresses_beyond_fencing` +
`run_migrations_applies_consolidated_initial_schema_on_fresh_database`:
pass.
- `cargo fmt --all --check` clean; `cargo clippy -p buzz-db -p
buzz-search --all-targets -D warnings` clean.

Independent of #4999 — both main and #4999 are brownfield-exposed today;
this lands either order.

b622003f74 broker: define the agent-to-broker action contract (#6742)
Addresses the interface half of #6467.

This is the contract for how a keyless agent asks a host to act on its
behalf — and only that. No host, no transport, no signing, no Desktop
code; the only implementation is a test double. An agent that holds no
secret key still has to read its channels, answer a mention, react, keep
its profile, address its memory, and create the agents it needs. This PR
defines the vocabulary for those requests and the rules both sides must
follow.

**#6467's open question, answered: per-operation, not "sign this".** A
raw signing primitive tells the host *who* is asking but not *what for*,
so the only policies it can express are all-or-nothing. A closed set of
named operations lets a host serve channel reads while refusing agent
creation, and gives any later policy layer something to attach to. The
cost is that adding an operation means changing the contract — which is
the point. Signing, publishing, and the auth/encryption NIPs are
deliberately *not* operations; they are mechanisms inside whoever holds
the key, and a test pins that none of those names resolve.

**Nine operations in v1:** read a channel (whole channel, one thread, or
mentions-only — these differ by filter, not permission, so they share
one operation), post, reply, react, set profile, derive a storage
address, and create / update / delete agents. Presence and typing are
deferred as housekeeping a host may decline regardless; streaming is
deferred, so waking on a mention is a polled mentions-only read. Each
operation has typed, validated arguments and a typed outcome.

**What the contract enforces structurally rather than by instruction:**

- *Retry means identical bytes.* A request is validated and serialized
exactly once and the transport only ever sees that frozen form. There is
no way to re-render it, so a retry can't drift and be mistaken for a
conflicting request.
- *Read cursors are opaque.* Host-issued strings, validated for shape
only, never parsed or compared. The host owns ordering and paging
stability instead of being locked into timestamps.
- *Reads return signed Nostr events.* A keyless agent verifies
authorship and content locally and trusts the host only for completeness
and authorization. Reply ancestry and mentions are derived from the
signed tags, so nothing can disagree with the signature.
- *Validation is the only door to a response.* The transport primitive
hands back an unjudged envelope; the only response a caller can actually
obtain is one already checked against the request it answers — request
id correlates, the outcome's operation matches, identifiers and cursors
are well-formed. A mismatch counts as "no answer", not a failure
verdict. The raw primitive can't be invoked from outside the crate
(pinned by compile-failure checks), so skipping that step isn't an
option.
- *Authority is never asserted by a body.* The envelope has no
requester, owner, scope, or credential field; all of that comes from the
session the host authenticated. Ownership of a created agent is
implicitly the requester, never a field — which is what lets agents own
agents while the chain still ends at a human.
- *No secret crosses the wire.* Agent creation returns a pubkey and
handle, never the minted key. Every payload type rejects unknown fields,
and a test pins the exact JSON key set of all eighteen argument and
outcome types, so no field can be added without a reviewer touching that
table. Two honest limits: a string can physically hold secret text, so
keeping secrets out of message content is host policy; and nothing stops
a host from *holding* keys — it just may not hand them over.
- *Null is never legal; omission is the only spelling of absence.* Every
optional member rejects an explicit null. Otherwise null and omitted
would be indistinguishable, and a contradiction check on the response
envelope could be skipped by sending one (a real hole in an earlier
revision). Coverage is derived by walking every path in the real
fixtures, so new optional members are covered automatically. Serializers
that emit null by default (Go without `omitempty`, Python's default
dump) need configuring — called out in the module docs.

**Wire mapping.** One POST endpoint, JSON body is the frozen request,
opaque bearer credential in the auth header. Every verdict the host
reached — including failure and including a rejected credential — comes
back as a well-formed envelope with 200, because a second copy of the
verdict in the status line could only disagree with it. Clients still
try to parse an envelope regardless of status (intermediaries may remap)
and fall back to the status only when none is present. A rejected
credential is a host verdict carrying the promise "the action did not
run"; transport errors are reserved for "nothing can be concluded about
side effects." Binding the credential to a specific agent and
conversation is the host's job and deliberately unenforceable here.

**Relationship to #6543.** Envelope, request-id rules, protocol version,
the three-way succeeded / failed / indeterminate result, error codes,
and the agent-management argument shapes carry over. Changed
deliberately: pubkeys are a validated type rather than bare strings,
"capability" became "action" throughout, and a new "unsupported" error
lets a host decline a best-effort operation without it reading as a
fault. Both PRs land in the same module path — whichever merges second
needs a hand reconcile, which I own as the author of #6543.

**Validation at `7c853e0fb`.** 299 tests in the sdk crate (full package
run), workspace tests green apart from the pre-existing relay timeout
flake, which I reproduced on unmodified `main`. Clippy with warnings
denied, fmt, warning-free docs, and the pre-push gate all pass. Review
findings were closed with mutation tests — each fix verified by
reverting it and watching a named test fail. One of those exposed a gap
in my own coverage (response-side fields weren't pinned); that's fixed
and floored separately from the request side so neither can mask the
other.

**Size.** About 5,400 lines across 8 files, roughly half tests. Every
source file is under the repo's 1,000-line cap except the test file;
#6759 splits it mechanically, is stacked on this branch, retargets to
`main` after merge, and lands before PR 2 of the stack.

8f3566ad9e Deduplicate ACP thread prompt context (#6706)
## Why
This is a small isolated follow-up to
[#6503](https://github.com/block/buzz/pull/6503): remove two proven
duplicate prompt fragments without adopting its broader framing
experiment or changing Buzz-native routing and identity behavior.

## What
- Remove parsed `parent=<id>` only when it exactly duplicates parsed
`root=<id>`; retain `root=<id>`, nested parents where parent differs
from root, raw event tags, event IDs, author identity, mention fields
and rules, and the explicit `--reply-to` instruction.
- Remove the full-history retrieval hint only when complete, untruncated
conversation or thread context is included. Thread context must include
its root and cover every event rendered in the batch; mixed-thread
batches and root-missing windows retain retrieval guidance. Context that
is absent, previously delivered, or truncated also retains retrieval
guidance, and the context header, count, and messages remain unchanged.

## Risk Assessment
Low — the change is confined to Buzz ACP prompt rendering and preserves
all routing, identity, event, and retrieval information outside the two
exact duplicate cases.

## Testing
- `cargo test -p buzz-acp` — 804 unit tests and 9 lifecycle integration
tests passed on the clean rerun
- Focused mixed-thread, same-thread, and missing-root prompt regressions
passed
- The timing-sensitive `keepalive_resets_idle_past_deadline` test passed
in isolation after one unrelated full-suite flake, then passed in the
clean full rerun
- `cargo clippy -p buzz-acp --all-targets -- -D warnings`
- `cargo fmt --all -- --check`
- `just file-size-check`
- Repository pre-push gate at `1b88793574e74e22f00a1fd19bfe9aa8e86150fa`
— file-size, branch, Rust unit-test, and Desktop Tauri lanes passed
- `git diff --check`

de188ebf06 feat(projects): add agent and CLI project-home support (#6590)
## Summary
- inject bounded project-home identity and repository context into
managed agent sessions
- add project-aware CLI flows for creating projects, repositories,
issues, and related channels
- match project homes through the existing relay query surface, then
filter channel metadata client-side

This is Part 1 of the channel-first Projects stack. Part 2 contains
project creation and model foundations.

## Testing
- `cargo fmt --all -- --check`
- `cargo clippy -p buzz-cli -p buzz-acp --all-targets -- -D warnings`
- `cargo test -p buzz-cli -p buzz-acp` — 1,184 tests passed, 1 doc test
ignored
- full pre-push gate passed

## Post-Deploy Monitoring & Validation
- validate project-home agent context and project-aware CLI commands
against a staging relay
- healthy signals: project context matches the active channel, explicit
repo coordinates remain stable, and normal channels receive no project
block
- failure signals: cross-channel project context, duplicate project
creation, or commands targeting an unrelated repository; mitigate by
reverting this PR

f177f4909d Use paired tags for standing & per-turn context (#6701)
## Why
PR #6503 bundled a broader context compiler with several prompt-shape
and telemetry changes, making it difficult to isolate whether paired
XML-like top-level boundaries improve agent behavior. This keeps the
follow-up experiment focused on framing only.

## What
- Replace top-level standing and per-turn bracket headers with paired
tags while preserving inner section content and event/message framing
- Carry only metadata already present in dynamic headers as attributes,
such as thread counts, truncation, event type, and batch count
- Preserve every section body verbatim so the model executes the exact
bytes reviewed in Desktop
- Keep routing metadata, event content, batching, and delivery behavior
unchanged
- Teach Desktop diagnostics to parse the new framing while retaining
compatibility with archived bracket-framed sessions; ambiguous paired
boundaries render as the complete captured prompt

## Risk Assessment
Medium — the change is limited to agent prompt framing and diagnostic
parsing, but it affects both standing context and every dynamic agent
turn. Bodies and delivery behavior remain unchanged, and compatibility
parsing remains for prior sessions.

## References
- Follow-up to #6503, scoped only to the paired-tag framing hypothesis

## Update — 2026-08-24
- Addressed review feedback by removing entity encoding/decoding from
the execution and diagnostic paths.
- Added regressions for literal closing tags, placeholders,
entity-looking text, ampersands, and authored boundary whitespace.
- Verified `cargo test -p buzz-acp` (805 unit + 9 integration), Desktop
tests (5,412 before the main sync; 5,439 in the pre-push gate), Desktop
typechecking, and Tauri clippy/tests.
- Live local relay startup and message ingestion passed. The live ACP
reply step is blocked locally because installed Goose 1.0.23 no longer
provides the documented `goose acp` command and no alternate ACP adapter
is installed.

---

**Update Aug 25, 12:13 EDT:** Extended paired tags to per-turn top-level
sections.

- Converted context, conversation/thread context, event batches, and
steer/interrupt boundaries without changing their inner bodies.
- Preserved existing header metadata as attributes only; added no new
prompt metadata.
- Verified 806 Buzz ACP unit tests plus 9 integration tests, 5,441
Desktop tests, Desktop typechecking and formatting, and all differential
pre-push lanes.

---

**Update Aug 25, 13:58 EDT:** Addressed framing review feedback.

- Updated operational base instructions to reference the emitted
`<context>` section and added a regression guard against stale
`[Context]` instructions.
- Restored batched steer/interrupt cardinality in Desktop diagnostic
titles with focused coverage for both paths.
- Verified 807 Buzz ACP unit tests plus 9 integration tests, 5,442
Desktop tests, Desktop typechecking and formatting, and every
differential pre-push lane including Tauri clippy/tests.

---

**Update Aug 25, 15:37 EDT:** Hardened legacy transcript compatibility.

- Semantic standing-context parsing now requires paired framing at the
start and complete input consumption.
- Historical bracket-framed personas keep literal balanced tag examples
in their original section; malformed or mixed current framing displays
as the complete captured prompt.
- Added regressions for the reported legacy persona case and trailing
unframed text; verified 60 focused parser tests, 5,444 full Desktop
tests, formatting, and typechecking.

---

**Update Aug 25, 16:31 EDT:** Preserved slash-command prompt block
boundaries.

- Desktop now sets aside a valid connector-facing slash-command block
only when the following block begins recognized paired framing, parses
the semantic blocks normally, and retains the command as visible Prompt
metadata.
- Added an end-to-end transcript regression using the production
three-block ACP shape, including the user bubble, author pubkey, event
ID, and grouped prompt context.
- Verified 113 combined transcript tests, 5,445 full Desktop tests,
formatting, typechecking, and all applicable pre-push lanes.

583af02299 fix(cli): preserve signatures in event reads (#6884)
## Summary
- preserve string Nostr `sig` values in normal `messages get`, `messages
thread`, `messages search`, and `feed get` output
- omit absent or non-string signatures instead of fabricating empty
values
- keep compact output at exactly `{id, content, created_at}` and update
CLI/managed-agent contract docs

## Validation
- `cargo test -p buzz-cli --lib` (367 passed at final head
`a2498faa0e07f90efc0ab0165606ba3b048327c7`)
- release candidate live-relay matrix: 49/49 normal events independently
recomputed to their NIP-01 IDs and passed BIP-340 verification; all four
compact commands preserved exact three-key output and ordering
- `git diff origin/main...HEAD --check`
- independent adversarial review: clear, no findings

## Compatibility
The normal JSON change is additive for valid relay events. In-repo
consumers use tolerant field lookup. Compact output is unchanged and
locked by regressions for both message and feed formatting.

ef0d202568 refactor(db): finish replaceable event store extraction (#6777)
## Why
Finish the replaceable-event slice of [tracker
#2](https://github.com/TheSentinel454/buzz/issues/2) and [domain issue
#6](https://github.com/TheSentinel454/buzz/issues/6) without disturbing
the runtime/store boundary established by #6660 and #6668. PR #6700 has
merged; this PR now targets current main containing its replacement lock
and transaction observability.

## What
- Move `Db::replace_addressable_event`, its SQL, lock/transaction
instrumentation, and focused addressable/parameterized replacement tests
from `lib.rs` to `replaceable.rs`
- Preserve the transaction-required parameterized API, replacement
ordering, rollback semantics, mention indexing, and exactly one
datastore span per public operation
- Keep implementation and focused PostgreSQL tests co-located; follow-up
review removed the dedicated replaceable ownership source guard as low
value

## Stack
- Exact base: main at f249710331
- Exact head: codex/issue-6-finish-replaceable-store at

- Test/span acceptance: https://github.com/TheSentinel454/buzz/issues/17
and https://github.com/TheSentinel454/buzz/issues/19

## Non-goals
- No SQL, schema, retry, timeout, lock ordering, transaction boundary,
or client-visible behavior changes
- No store traits, domain-handle redesign, `PgExecutor` migration, raw
pool accessor, new crate, or directory reorganization
- No changes to, retargeting of, or merge action on PR #6700

## Risk Assessment
Low. This is a mechanical ownership move with unchanged signatures and
SQL. The primary review risk is losing or nesting instrumentation,
covered by exact moved PostgreSQL tests and the cumulative
production-diff audit.

8471049c43 feat(desktop): add KLIPY GIF search to composers (#5554)
## Summary

- Supersedes #1913 with a KLIPY-hosted URL implementation.
- Adds KLIPY GIF search and trending results to desktop message and
forum composers.
- Keeps selected GIFs hosted by KLIPY; Buzz stores only the external URL
and media metadata (no imeta tag, since relays only accept hash-backed
local `/media/` entries).
- Aligns the Emoji/GIF picker with Buzz's standard segmented control,
theme surfaces, and motion behavior.

## Relay-to-provider boundary

- The relay proxies KLIPY search/share so the `BUZZ_KLIPY_API_KEY` never
reaches the desktop; the key stays server-side behind a redacted `Debug`
impl.
- The dedicated GIF `reqwest` client sets `redirect::Policy::none()`.
Because the API key rides in the request path, following a provider
`3xx` could replay a key-bearing URL to an attacker-chosen host (an
SSRF/key-disclosure primitive). With redirects disabled, a `3xx` returns
as a non-success status that the handlers map to a generic `502`; the
`Location` target is never read or forwarded.
- Admission reuses the established NIP-98, membership, replay, and
per-pubkey rate-limit gates, with an upstream response-size cap and
allowlisting so KLIPY error bodies never cross the relay boundary.

## Accessibility

- Under `prefers-reduced-motion: reduce`, the picker grid renders a
static provider poster (a normalized `jpg` asset) instead of the
animated preview, or a named static placeholder when no poster is
available. It reacts to preference changes while mounted.
`no-preference` keeps the animated preview.
- Selected GIFs carry their title through `ImetaMedia`'s `displayLabel`,
so the composer thumbnail, preview dialog, editor, lightbox, and remove
control all derive one non-empty accessible name instead of an empty
`Attachment ` label. Ordinary hashed uploads keep their existing
hash-derived names.

ee6ca5fa28 Remove public relay signing key fallback (#6729)
Require `BUZZ_RELAY_PRIVATE_KEY` on every relay startup and remove the
shared public fallback key completely.

For local development, `just bootstrap` now generates a random key once
in the gitignored `.env` file. Re-running bootstrap preserves that key,
so relay-authored events retain the same identity across restarts. The
local relay recipes reload `.env`, while isolated CI and E2E launchers
pass explicit per-run keys.

Startup fails immediately when the key is missing or invalid, before
connecting to Postgres or Redis. Deployed relays continue to receive
their stable key from the existing chart-managed secret.

Validated with:

- `./scripts/test-ensure-local-relay-key.sh`
- `cargo test -p buzz-relay --bin buzz-relay`
- `cargo clippy -p buzz-relay --bin buzz-relay -- -D warnings`
- `cargo fmt --all -- --check`
- `shellcheck scripts/ensure-local-relay-key.sh

f249710331 Qualify canonical relay images for staged delivery (#6781)
## Why

Phase 1 of progressive delivery needs an explicit eligibility boundary
before deployment automation can safely consume relay artifacts. Today
the canonical Docker workflow can publish independently of the same-SHA
CI result, the relay does not expose its source/build identity, and the
Helm chart only renders mutable tags.

The existing `ghcr.io/block/buzz-staging-dev` workflow in #6709 remains
a manual pre-merge preview lane. It is deliberately not a canonical
promotion input.

## What changed

- Compile the full source SHA and GitHub Actions build identity into
canonical relay binaries and expose it at `/_status`.
- Gate creation of tagged multi-architecture manifests on the latest
exact-SHA `CI` push run succeeding on `main` or `release`.
- Preserve the signed SLSA provenance and add a signed, release-only
deployment-eligibility predicate with source, build run, qualifying CI
run, and exact compatible Buzz chart version.
- Keep failed or pending builds untagged and without an eligibility
predicate; preview-package artifacts are excluded by package and signer
contract.
- Add optional `image.digest` support to Buzz chart `0.1.8`, retaining
the existing tag fallback.
- Document verification and the intentional boundary between image/chart
compatibility and backwards-compatible database migrations.

## Risk and rollout

Canonical tag publication now waits for same-SHA CI and fails closed
when the newest matching run fails. Per-architecture blobs may remain
untagged after a failed qualification; they are not promotion inputs.
Debug manifests are also CI-gated but do not receive the release
eligibility predicate.

There are no migration or schema-orchestration changes. The companion
BuilderBot infrastructure PR will pin a separately verified canonical
main digest and expose a read-only running-deployment inspection
command. Signed eligibility is available only for artifacts published
after this workflow lands.

## Verification

- Blox: workflow contract fixtures, including stale-green rejection and
predicate structure
- Blox: `actionlint` for `ci.yml` and `docker.yml`
- Blox: 46 Helm unit tests, chart lint, and production/quickstart render
fixtures
- Blox: relay status unit test, workspace Rust formatting, and workspace
all-target clippy
- Live evidence: exact-SHA CI selector chose successful run
`32857345153` for source `9d1e4b257657f382d3111ce748f3da8d063b7671`
- Existing canonical digest provenance verified with `gh attestation
verify`

canonical eligibility

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.

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.

instrumentation tests, DB unit tests, source privacy guards, and

a1219070fa feat(buzz-agent): gate LLM tool calls on session/request_permission (#5712)
## Summary

buzz-agent now authorizes every LLM-issued MCP tool call through
`session/request_permission` before it executes, instead of running
tools unconditionally. The agent **always asks**; the client applies
`BUZZ_ACP_PERMISSION_POLICY` and answers. buzz-agent never reads the
policy — this keeps the policy decision on the client side, matching the
layering of the other ACP harnesses, and avoids duplicating policy logic
that would drift.

### Broker

A crate-local `PermissionBroker`
(`crates/buzz-agent/src/permission.rs`), owned by `App` for the
connection lifetime, owns the full request-correlation lifecycle:

- **Process-wide admission.** A global `Semaphore`
(`BUZZ_AGENT_MAX_PENDING_PERMISSIONS`, default 32, validated `>= 1`) is
acquired *before* any correlation entry is inserted. This is the
security bound: the per-turn tool semaphore is constructed fresh per
turn and `max_sessions` is unbounded by default, so neither bounds
simultaneously-outstanding asks process-wide.
- **Abort-safe cleanup.** A successful admission returns a
`PendingPermission` lease that owns the admission permit and the
correlation id. Its `Drop` synchronously removes the still-pending entry
and releases the slot, covering task abort/panic that bypasses the
normal `run_prompt` tail.
- **At-most-once resolution.** `deliver` claims (removes) the entry
*before* waking the waiter, so each id resolves once and a later lease
`Drop` is a no-op. Unknown/late ids are logged and dropped; only ids the
broker minted (`perm-<n>`) are recognized.
- **Single absolute deadline.** Admission, request enqueue, and response
wait all share one deadline (`BUZZ_AGENT_PERMISSION_TIMEOUT_SECS`,
default 330s, validated `>= 1`), so a saturated call cannot outlive one
timeout window even when a stalled writer blocks the enqueue.
Cancellation races inside every wait — resolution never depends on the
outer abort drain. A writer that dies mid-connection (stdout closed, or
a blocking write that only surfaces its error at flush) is
connection-fatal: it cancels all sessions, which resolves any ask
waiting on a reply that can never be written.

### Wire

`request_permission_params` (`crates/buzz-agent/src/wire.rs`) is
version-aware, keyed on the protocol version negotiated at `initialize`
and stored on `App` for the connection lifetime (never derived from a
later mutable session field). v2 nests the tool call under `subject:
{type: "tool_call", toolCall}` with top-level `title`/`options`; v1 uses
the legacy top-level `toolCall`. No hybrid shape. Both offered options
(`allow_once`, `reject_once`) carry `optionId == kind`, so the client's
`kind`-based selection and this side's `optionId`-based predicate agree
without a lookup table.

### Gate

In each spawned tool task (`crates/buzz-agent/src/agent.rs`) the
sequence is: acquire per-turn permit → argument-shape validation →
broker admission + request + wait → cancellation recheck →
`emit_in_progress` → `mcp.call`. Argument-shape validation is hoisted
out of `mcp.rs::do_call` into `validate_arg_shape` so a malformed
non-object argument is rejected locally without prompting for a call
that could never execute.

Authorization is fail-closed, stated once in `evaluate`: execute IFF
`outcome.outcome == "selected"` **and** the selected `optionId` equals
the offered allow option. Every other shape (reject, cancelled, JSON-RPC
error, malformed, unknown outcome, wrong/unknown option, timeout,
wire-channel closure) denies with a synthetic tool error, and the turn
continues.

### Scope

Only LLM-issued MCP calls are gated. The built-in `load_skill` tool and
`call_hooks` lifecycle calls (`_Stop`, `_PostCompact`) are exempt — they
are not model-issued. `readOnlyHint` is never treated as a security
boundary.

First cut ships `allow_once`/`reject_once` only; session-scoped grants
are deliberately out of scope.

### Related issue

Part of #4938. This PR and
[#5106](https://github.com/block/buzz/pull/5106) jointly implement the
feature: #5106 is the client-side policy engine and permission cards;
this PR is buzz-agent's asking side (`session/request_permission`).
Neither closes #4938 alone.

9d1e4b2576 Extract community persistence (#6668)
## Why

Community persistence is the next incremental `buzz-db` store
extraction, keeping tenant lifecycle SQL, records, tests, and
instrumentation out of the database runtime module without changing
behavior.

## What

- Move community records and the existing `impl Db` operations into
`community.rs` while preserving crate-root re-exports.
- Move focused PostgreSQL tests with the implementation and enforce
single ownership for each method and datastore span.

## Risk Assessment

Low — this is a structural move of the existing records, SQL, method
bodies, and focused tests; database runtime concerns, schema, and
behavior remain unchanged.

8d2d0ff5ad Centralize replaceable event persistence (#6660)
## Why
Command persistence duplicated NIP-33 replacement SQL in the relay and
obscured the boundary between database runtime concerns and domain-store
behavior. This proving slice establishes that boundary inside the
existing `buzz-db` crate.

## What
- Centralize parameterized-replaceable coordinate locking, ordering,
replacement, watermark, and mention-indexing behavior in `buzz-db`
- Expose transaction-required replacement and ordinary-insertion seams
while keeping transaction ownership and workflow conflict messages in
the relay
- Cover concurrency, same-second ties, stale writes, replay, caller
rollback, nested rollback recovery, and mention-index atomicity with
focused PostgreSQL tests

## Risk Assessment
Medium — this changes core event persistence and command idempotency
paths, while intentionally preserving NIP-33, NIP-RS, mesh, and workflow
conflict semantics.

2d280376ad perf(desktop): persist channel heads, collapse thread reads and reply sends (#6572)
## Summary

Lands the build-now items from the desktop latency plan
(#ui-performance-deep-dive) as one change. Every perceived-latency hot
path a user hits on launch, channel open, thread open, and reply send
drops one or more round trips.

**A1 — persisted channel heads (the big one).** Native WAL SQLite cache
(`desktop/src-tauri/src/channel_head_cache.rs`) keyed by `{pubkey,
relayUrl}` scope, 32 rows/scope LRU, 1 MiB per-row drop cap,
schema-version reset, corrupt-row tolerance, checkpointed on shutdown.
Three blocking-pool commands: `channel_head_cache_load` / `_store` /
`_clear`. On the renderer side, `CommunityQueryProvider` kicks off
hydration of up to 12 heads when it constructs the query client — the
app, splash and relay preconnect mount immediately; only
`useChannelMessagesQuery` awaits the seed (`channelHeadHydration`), then
consumes a one-shot hydrated gate so a hydrated channel pays **zero**
`get_channel_window` calls on mount and exactly **one** on the
post-subscription refresh, whose response replaces page zero wholesale.
That refresh fires whether live-subscription setup succeeds or fails,
and is sequenced behind hydration so it is always a distinct
authoritative fetch (see Review follow-ups). Bounds-only persisted heads
(zero rows) are not hydrated and take the cold loading path. The
timeline loading latch recognizes native-hydrated rows as restart-safe
so they paint immediately instead of holding a skeleton. The cache is a
paint accelerator only — the relay response is always authoritative.
Replaces the legacy localStorage `messageSnapshot.ts` (removed, -401
lines).

Kill switch: `VITE_BUZZ_CHANNEL_HEAD_CACHE=off` at build time or
`localStorage["buzz-channel-head-cache"] = "off"` at runtime. Cache is
cleared on community removal and scoped per identity, so a replaced
signer never sees the previous identity's rows.

**B1 — thread aux in one response.** Relay thread filters accept
`include_aux`; the bridge appends the same authorized two-hop
reactions/edits/deletions closure a channel window gets
(`build_aux_query` shared with the window path). Renderer
`useThreadReplies` drops its two follow-up aux fetches. `next_cursor` is
computed from reply-kind rows only since aux rows are unpaged.
Documented in `docs/bridge-channel-window.md`. Thread queries keep
`staleTime: 0` (`bcfe04e2f`): an earlier revision raised it to 30s,
which CI's `thread-unread.spec.ts` caught — once the user leaves a
channel, the live subscription stops feeding that thread's cache, so a
reopen must always take the (now single) authoritative read.

**B2 — cached root on reply send.** `send_channel_message` gains
`root_event_id`; when the renderer already holds the parent (channel or
thread cache) it passes the NIP-10 root, and native signs without the
relay round trip that `resolve_thread_ref` used to make. Strict hex
parse; `root_event_id` requires `parent_event_id`; absent root falls
back to the existing relay resolution. The renderer never sends a
guessed root.

**B4** general HTTP pool idle 10s→300s, max idle per host 1→2. **B5**
relay preconnect fires as soon as identity is ready instead of waiting
for `requestIdleCallback`. One e2e test (`relay-reconnect.spec.ts`
"service restart close resets accumulated backoff") had been relying on
the idle-callback batching to skip past its own seeded dial failures
before the channel list painted; `8133d70bb` makes it wait for the
connected state instead (test-only, still fails with the 1012 backoff
reset disabled). **B6** profile freshness 60s→10 min (both the in-memory
entry check and the query `staleTime`). Tradeoff: another user's
display-name/avatar edit can take up to 10 min to propagate to a client
that already holds their profile (relay reconnect refetches
`users-batch` but resolves from the still-fresh per-pubkey entry); your
own edits still evict the entry immediately (`evictUsersBatchEntries` in
`useUpdateProfileMutation`).

and
[5002596542](https://github.com/block/buzz/pull/6572#pullrequestreview-5002596542),
each pushed as new commits (no rebase):

- `4f06b7770` fix(desktop): mount app while channel heads hydrate;
always revalidate — provider no longer gates children on the cache load;
`refreshAfterSubscribe` runs on subscribe failure too; bounds-only heads
skipped at seed; seed merges into an existing window store. +3 tests.
- `35834cb31` fix(relay): drain aux closure hops across the page clamp —
`query_all_pages` walks the `(created_at, id)` keyset via
`until`/`before_id` until a short page (`AUX_PAGE_LIMIT` =
`DEFAULT_MAX_PAGE_LIMIT`, `AUX_MAX_PAGES` = 64 warn+truncate) so
one-shot `limit: 1000` newest-first no longer drops the oldest
edits/deletions. +3 tests; `docs/bridge-channel-window.md` updated.
- `db21b0531` merge of `origin/main` `e23632941` (#6558, #6312 — no
overlap).
- `5a5566c0f` fix(desktop): sequence post-subscribe refresh behind
channel head hydration — `refreshChannelWindowMessages` awaits
`channelHeadHydration()` and, for a hydration-seeded query (`data !==
undefined && dataUpdatedAt === 0`), the in-flight snapshot fetch before
invalidating. Without this, a subscription that settles before the
SQLite load invalidated a data-less in-flight query; TanStack dedupes
that onto the existing fetch (`query-core` `fetch()` only cancels when
`state.data` exists), which returned the seeded snapshot — 0
authoritative fetches. Regression test reproduces Carl's exact ordering
(fails at `35834cb31` with 0 calls), plus a cold-channel guard that the
fix does not double-fetch.
- `b129231c8` fix(desktop): let concurrent post-hydration refreshes
share one window fetch — found independently by Max and Wren reviewing
`5a5566c0f`: subscribe settlement + reconnect both wake on the same
snapshot promise and both invalidate; the second (default
`cancelRefetch: true`) cancelled and replaced the first authoritative
fetch (3 queryFn calls, not 2, and the cancelled Tauri invoke still hits
the relay). The seeded branch now invalidates with `cancelRefetch:
false` so a second waker joins the in-flight fetch; cold/warm keep the
default (`test_canceled_stale_fetch_cannot_overwrite_catch_up_window`
relies on it). Concurrent regression test fails at `5a5566c0f` with 3.

specs minus affordance); GitHub CI green on every job except Smoke (3)
(unrelated project-review row-count + messaging timing flake, per Carl)
and Unit Tests (sherpa cache skeleton, below).

Earlier, all at `8133d70bb` (this PR head is `0c492366d` = 8133d70bb + a
comments-only commit correcting two `profile/hooks.ts` freshness
comments from 60s to 10 min; pre-push desktop check/typecheck/test
5,387/0 re-ran at 0c492366d) in one shell; `origin/main` = `040b203f7`
at PR open, since moved to `4baccd539` (#6558, mobile only — zero file
overlap, `git merge-tree` clean):

- `just desktop-test` — 5,387 passed / 0 failed (includes new hook-level
call-count test: cold = 1, stale-prefetched = 1, hydrated = 0 on mount
then 1 on invalidate with wholesale replacement)
- Playwright smoke `relay-reconnect.spec.ts` + `thread-unread.spec.ts` +
`channel-head-restart.spec.ts` — 30/30 (thread-unread was 8/13 at
`7acbf951b`; relay-reconnect was 15/16 at `bcfe04e2f`). The restart spec
persists a head, reloads into a fresh mock relay with the head fetch
held 5s, asserts the persisted row paints within 2s, exactly one
`get_channel_window` after open, and the stale row is removed when the
authoritative page lands.
- `pnpm typecheck`, `pnpm check` — clean

At `7acbf951b` (everything except the two-line `useThreadReplies.ts`
staleTime revert and the test-only `relay-reconnect.spec.ts` change),
also green in one shell:
- `just desktop-tauri-test` — 2,859 passed / 0 failed across the
workspace (channel_head_cache: wire shape, LRU+caps, schema reset,
corrupt-row skip)
- `just test-unit` — 632 passed (buzz-core/auth); `cargo test -p
buzz-relay --lib` — 908 passed / 0 failed
- `just check` components: fmt-check, clippy, desktop-check,
desktop-typecheck, desktop-tauri-fmt-check, desktop-tauri-clippy,
web-check, mobile-check, file-size-check — all green
- `just desktop-build`, `web-build`, `desktop-tauri-check`,
`mobile-test` (1,661 passed) — all green

CI note: the "Unit Tests" job goes red on this PR and on `main` whenever
it hits a poisoned `rust-cache` entry (an empty-directory skeleton of
`target/sherpa-onnx-prebuilt` that `sherpa-onnx-sys` build.rs trusts),
surfacing as `could not find native static library sherpa-onnx-c-api` in
`buzz-voice` — a crate this PR doesn't touch. Deleting the cache entry
and rerunning turned the job green at `0c492366d` (28/28); it re-poisons
on the next `main` push until the workflow clears that directory after
cache restore.

Reviewed in-channel by Wren (9 / 9 / 9.5) and Eva (9 / 9 / 9), and
line-by-line by me before opening; the staleTime fix re-verified by Wren
and me independently; the relay-reconnect test fix bisected and verified
by me.

f99532585a refactor(acp): clarify agent prompt sections (#6501)
## Why
The ACP prompt puts a machine-specific Workspace prefix before static
base guidance and labels the user-facing agent instruction layer as the
generic System section. Because the cwd varies by launch and worktree,
leading with it reduces reusable prompt-prefix stability.

`[Workspace]` was added in [PR
#1194](https://github.com/block/buzz/pull/1194) as a defensive fix after
a broken `~/.sprout` → `~/.buzz` migration caused agents to scan `$HOME`
and trigger macOS TCC prompts. This change retains that grounding while
shrinking it to the current working directory and moving dynamic
environment context after the static Base prompt.

## What
- Emit the prompt in Base → Workspace → Agent Instructions order
- Reduce Workspace to `Current working directory: <absolute path>`
- Resolve cwd as an absolute native-platform path and preserve Windows
drive/UNC paths instead of checking for a leading `/`
- Emit Agent Instructions for persona and standalone agent instructions
across modern and legacy ACP paths
- Preserve parsing for archived observer frames that used System or the
former Workspace-before-Base order, and align the persona catalog label

## Risk Assessment
Medium-low — this changes prompt framing for every newly created agent
session. Existing archived observer frames remain parseable, and
execution still uses the same ACP working directory. Cwd resolution now
fails clearly instead of substituting `/` when the process directory
cannot be resolved.

## Summary
- add foreground mobile Huddles on Android and iOS with native Opus
capture/playback, mute, speaker routing, participants, lifecycle, and
minimized drawer UI
- keep mobile Huddle cards and roster state live, including ended rooms,
relay-resolved profiles, and agents
- broadcast desktop agent TTS through the existing Huddle audio protocol

## Scope
Foreground human-to-human voice MVP only. Agent setup/transcripts,
background calling, recording, and advanced device controls remain out
of scope.

## Validation
- `just mobile-check`
- `just mobile-test` — 1,500 passed
- `just desktop-check` and `just desktop-test` — 4,957 passed
- desktop typecheck, strict Clippy, and Tauri tests — 2,445 passed, 15
ignored
- mobile worktree identity contract checks
- physical Pixel/iPhone behavior reviewed during development

47526784d5 fix(deletion): allow IRSA S3 credentials (#6495)
## Why
`buzz-admin deletions` runs inside bb-public relay pods, where S3
credentials are provided by the pod credential chain rather than static
`BUZZ_S3_ACCESS_KEY` / `BUZZ_S3_SECRET_KEY` values. The deletion CLI was
requiring those two env vars to be non-empty before constructing the
shared media storage client, so it could not reach the existing default
AWS credential chain.

## What
- Treat missing/blank deletion S3 access key and secret key as an empty
credential pair so `MediaStorage::new` can use `Credentials::default()`.
- Keep the existing static-credential path unchanged when both values
are non-empty.
- Keep deletion unit tests deterministic by covering only deletion env
normalization for missing/blank pair, trimmed static pair, and
partial/whitespace-partial outputs; shared media tests continue to own
credential-pair enforcement.

## Risk Assessment
Low and scoped to the operator-only community deletion CLI startup path.
The shared media storage credential validation still owns
static-vs-default credential selection and still rejects mixed partial
credentials.

## Testing
At committed head `0a86c2914b1f97caf4788a771048aa8d9d9d88ac` with a
clean worktree before and after (`git rev-parse HEAD` before/after
matched):
- `just fmt-check` — passed.
- `cargo test -p buzz-deletion` — passed: 12 passed, 9 ignored.
- `cargo test -p buzz-media` — passed: 120 passed;
`static_creds_round_trip_against_minio` remained ignored because it
requires live MinIO.
- `cargo test -p buzz-admin` — passed: 1 passed.
- `cargo clippy -p buzz-deletion --all-targets -- -D warnings` — passed.
- Startup smoke at the same head: built `buzz-admin`, then ran
`target/debug/buzz-admin deletions drain` with `BUZZ_S3_ACCESS_KEY=` and
`BUZZ_S3_SECRET_KEY=' '` plus `AWS_ACCESS_KEY_ID` /
`AWS_SECRET_ACCESS_KEY` fallback credentials; command exited `0`,
proving startup transitions past deletion S3 key validation and
exercises the shared default credential-chain branch using AWS env
fallback credentials.
- `git push origin HEAD:seiler/deletion-irsa-credentials` — passed;
pre-push hooks passed.

Not run: the full `TESTING.md` live-local relay workflow. Docker Desktop
currently refuses CLI access on this machine with `Sign in to continue
using Docker Desktop. Membership in the [squareup] organization is
required.`
