tornquist	8ebe3b881c	Record that owner deletion consent is an operator assertion ... The admission path reads as if the relay had verified the owner's consent. It has not: the mediating operator authenticates the owner and collects the acknowledgement out of band, and the request reaching the relay carries only that operator's NIP-98 signature. The relay checks operator authority and current ownership, and stores the owner pubkey, operator pubkey, and acknowledgement version as provenance for the upstream ceremony — never an owner-signed attestation. Also record how manual handoff converges. Owner provenance pins `requested_by` to `owner_pubkey`, so `buzz-admin deletions submit` must repeat the owner pubkey to adopt an admitted request; the operator's own pubkey conflicts with the one-active-request invariant instead.

Luke Tornquist	bd73490418	ci: run PostgreSQL tests in isolated lane (#6730) ... ## Why PR #6660 introduced four PostgreSQL-backed persistence tests and a focused CI selector, but an exact test-name list does not automatically cover future database tests. Broad ignored-test execution also exposed shared-schema races and ambiguity between desired-state and migration-applied schema expectations. ## What - Establish a discoverable convention: PostgreSQL unit modules use `postgres_tests`, PostgreSQL integration binaries use a `postgres_` prefix, and unrelated external-infrastructure tests use an `external_infra_` prefix. - Add a dedicated nextest PostgreSQL profile and archive-backed CI job covering the relevant crates without enumerating test names. - Create a run-scoped desired-state source database and a unique PostgreSQL database per test process for parallel-safe isolation, with cleanup on success, failure, or interruption. - Route destructive migration and migration-parity tests to clean `template0` databases while desired-state tests clone the desired-state database. - Document discovery, schema modes, required role privileges, and a bounded portable local runner. - Keep the existing infrastructure-free unit-test jobs unchanged. This is intentionally limited to test and CI harness behavior. It does not move production database code, change persistence semantics, or implement issue #20's broader shared test-utility refactor. ## Risk Low production risk because all changes are confined to tests, CI configuration, documentation, and test harness scripts. Remaining operational risks: - Cleanup retries `dropdb --force` five times across roughly four seconds. Exhaustion warns with the database name but deliberately does not mask the test result; individual PostgreSQL diagnostics are suppressed. - The seven-package boundary is duplicated between the runner and CI archive and must remain synchronized if PostgreSQL tests move to a new crate. - Portable SHA fallback branches were exercised on Linux; no macOS Blox workstation was needed for this Linux CI artifact. - GitHub's unchanged generic Unit Tests job currently fails while cold-linking `buzz-voice` because `sherpa-onnx-c-api` is absent. The branch changes no voice/build/toolchain inputs; the exact parent previously passed that job, and Blox passes the same infrastructure-free suite (1,450/1,450). A prior-head one-job retry and the final-head run both reproduced the hosted-runner failure. ## Verification Author Blox workstation `2020088`: - `cargo fmt --all -- --check` - `just clippy` - `just test-unit`: 1,450 passed; PostgreSQL tests remain skipped in fast jobs - PR #6660 focused tests: 4/4 passed through the final runner - Full lane: 282/282 passed in 10.087s with a non-superuser role limited to `CREATEDB`, `CREATEROLE`, and `pg_read_all_stats` - 272 desired-state tests - 10 migration-applied tests - 6 explicitly filtered external-infrastructure tests - Cleanup fault injection: a deliberately underprivileged 282-test run produced the expected 277 passes and 5 failures, and the post-run catalog audit found zero lane databases after retry cleanup. The restored successful run also left zero lane databases. GitHub exact final head `92c231e48f299ea2af23817763f5ae80ac013d68`: - [PostgreSQL Tests](https://github.com/block/buzz/actions/runs/32789030203/job/97630827823): 282/282 passed across 10 binaries in 98.886s; 1,240 skipped, including 6 via the profile filter - The shared relay/PostgreSQL archive predecessor completed successfully - [Unit Tests](https://github.com/block/buzz/actions/runs/32789030203/job/97626930420): unrelated `sherpa-onnx-c-api` native-link failure described above - Independent exact-head review on separate Blox workstation `2022762`: no substantive findings after all initial findings were addressed. The reviewer independently verified cleanup retry behavior, exit-status preservation, shell portability, syntax, and a clean exact-head worktree. ## References - Stacked on #6660 at exact head `561de54be4d9c2b622b7c2aa5b61bc3068f47e2a` - https://github.com/TheSentinel454/buzz/issues/20 - https://github.com/TheSentinel454/buzz/issues/20#issuecomment-5398526792 Generated with Codex. ## Update — August 24, 2026 review follow-up - Centralized the repeated PostgreSQL test URL resolution in crate-local, test-only helpers without introducing the broader shared utility refactor from issue #20. - Restored descriptive hybrid/Redis test function names. Structural `external_infra_*_tests` modules now own exclusion, and the nextest filter only recognizes module path segments. - Added a three-second source guard that scans every Rust file and fails CI when an ignored PostgreSQL test would be omitted or an external-infrastructure test would be included. Fixture tests cover accepted modules/binaries and both failure modes. - Removed the two implementation-plan documents. Performance profiling on Blox workstation `2027352` (same prebuilt archive and cargo-nextest 0.9.143 for every comparison): - Current per-test database model, 8 workers: 10.15–10.40s across three runs. The 283 `createdb` calls and 284 `dropdb` calls consumed 28.85–29.46 aggregate seconds, about 39–40% of aggregate test-process duration. - Reusing one database per worker without cleanup: 6.55–6.84s, about 35% faster, but all three runs failed because global matcher-queue tests inherited a quiesced community from an earlier test; the failing test varied with scheduling. - Reusing workers with `TRUNCATE … RESTART IDENTITY CASCADE`: all 282 tests passed, but total time regressed to 10.47–10.67s. The 265 truncate calls consumed 24.34–25.45 aggregate seconds, so truncation merely replaced most clone/drop cost. - Raising concurrency to 16 workers reduced one isolated-database run to 8.79s, but 24 workers exposed a cluster-global `pg_stat_activity` race. The profile remains at the proven-safe 8 workers. Decision: retain unique per-test databases. Harness cleanup uses `dropdb --if-exists --force`; it drops the database rather than truncating tables or deleting rows. Verification at local branch head `60086c1f6ee34a193c342255a5e8e6293b60e988`: - Discovery inventory: exactly 282 intended tests; all 6 hybrid/Redis tests present and structurally excluded. - PR #6660 focused persistence tests: 4/4 passed. - Full PostgreSQL lane: 282/282 passed three times; 1,240 skipped each run; wall time 9.72–9.96s without profiling shims. - Non-ignored tests with a desired-state database: 1,234/1,234 passed; one mesh-demo timeout from the first run passed immediately in isolation. - `cargo fmt --all -- --check` and all-target/all-feature clippy for `buzz-db`, `buzz-deletion`, and `buzz-relay` passed. Final independent re-review at exact head `42097c0136ab3fa8f0efe5720ae829c04575b9b6` on separate Blox workstation `2028455`: no substantive residual findings. The reviewer independently exercised ordinary strings, zero/one/three-hash raw strings, line/block comments, and string-contained lookalikes, then reran the full 353-file scan, shell syntax, Python AST parsing, and diff check. Independent review found that the source guard's initial regular expression could miss raw-string ignore reasons and treat a commented attribute as real. Final head `42097c0136ab3fa8f0efe5720ae829c04575b9b6` parses valid ordinary/raw Rust string literals only at attributes found in comment-sanitized source; regression fixtures cover both cases. The fixture suite, Python compilation, shell syntax, diff check, and full 353-file repository scan pass on Blox. ## Update — August 25, 2026 restack PR #6660 merged, so this follow-up was rebased from its former exact parent onto current `origin/main` (`8d2d0ff5ad42733e9949442c4b6358d0ba87f9a8`). The final candidate head is `05dcc2ab28948e3ab79bb44839a69f2ba44648a2`; the PR no longer carries #6660's pre-squash history. Fresh exact-head verification on Blox workstation `2028572`: - Discovery guard passed across 353 Rust files; inventory remained exactly 282 intended PostgreSQL tests. - PR #6660 focused persistence tests: 4/4 passed. - Full PostgreSQL lane: 282/282 passed three times; 1,243 skipped each run; wall time 9.70–9.87s. - `cargo fmt --all -- --check` and all-target/all-feature clippy for `buzz-db`, `buzz-deletion`, and `buzz-relay` passed. ## Update — August 25, 2026 final hosted verification - [GitHub PostgreSQL Tests](https://github.com/block/buzz/actions/runs/32801679226/job/97667835080): 282/282 passed in 53.787s; 1,243 skipped. - The final guard scanned all 353 Rust files successfully before the hosted lane ran. - The shared relay/archive prerequisite and infrastructure-free Unit Tests job both passed at exact final head `42097c0136ab3fa8f0efe5720ae829c04575b9b6`. --------- Signed-off-by: Luke Tornquist <tornquist@squareup.com> Signed-off-by: tornquist <tornquist@squareup.com>	2026-09-01 12:07:28 -04:00
Luke Tornquist	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`.

Brad Seiler	d12dea4e67	Support community deletion in versioned media buckets (#6738)	2026-08-25 09:02:18 -07:00
Brad Seiler	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.

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