…jsonl-export.sh The mol-dog-reaper order (reaper.sh) sends an ESCALATION mail to the mayor on every 30-minute tick that finds non-empty $ANOMALIES, with no per-message-key dedupe, no cooldown, and no wisp_type label. Persistent conditions — e.g. an hq schema gap where the dependencies table lacks the split target columns — therefore flood the mayor inbox. The most recent incident produced 20+ identical "ESCALATION: Reaper anomalies detected [MEDIUM]" mails over a 44-hour window; the earlier 158-mail JSONL-spike flood that motivated the prior wisp-compact retention work was the same class of problem in a sibling code path that the prior fix did not cover. This commit factors a shared bash helper, escalation.sh, sourced by both reaper.sh and jsonl-export.sh. The helper: - Computes sha256(subject + "\n" + body) as a dedupe key and stores the last-sent timestamp + a suppressed-while-in-cooldown counter in a caller-provided JSON state file (atomic mv writes). - Suppresses repeat sends within a configurable cooldown window (default 6 hours, GC_ESCALATION_COOLDOWN_SECONDS env override). - On the first send after a suppression streak, appends a one-line "[Suppressed N time(s) since <last_sent_at>; cooldown <s>s.]" footer so the operator sees the cadence rather than just the latest report. - Best-effort labels the resulting bead with wisp_type:escalation by parsing the new bead id from `gc mail send`'s "Sent message <id> to <to>" stdout line and calling `bd label add`. wisp-compact already honors wisp_type:escalation as the 7d retention class; untagged escalation mails were falling into the 24h default bucket. - Exposes clear_escalation_state(state_file, [subject]) so callers can wipe dedupe entries when the underlying condition resolves and the next firing should escalate fresh. Wiring: - reaper.sh sources escalation.sh, gets a new $PACK_STATE_DIR/reaper-state.json state file (reaper had no state file before), and routes its anomaly send through send_escalation_mail. When $ANOMALIES is empty on a tick, clear_escalation_state wipes the dedupe entry so a future genuine anomaly is not suppressed by the resolved one's cooldown. - jsonl-export.sh's send_spike_alert and the push-failure escalation now both call send_escalation_mail. record_archive_push_success additionally calls clear_escalation_state for the push-failure subject so a re-introduced push failure escalates fresh. This subsumes the unmerged label-jsonl-escalation-wisp-type branch (commit 61678a5), which added labelling but no dedupe; that branch can be closed in favor of this PR. Tests (examples/gastown/maintenance_scripts_test.go): - TestReaperEscalationSuppressesRepeatAnomalyWithinCooldown — two reaper ticks with identical anomalies result in exactly one mail and a suppressed_count=1 dedupe entry in the state file. - TestReaperEscalationClearsStateWhenAnomaliesResolve — anomaly tick, then no-anomaly tick (which must clear dedupe state), then anomaly tick again, must produce 2 fresh mails total. - TestReaperEscalationLabelsBeadAfterSend — when the gc stub mirrors real `gc mail send`'s "Sent message <id> to <to>" stdout, the follow-up `bd label add <id> wisp_type:escalation` lands in the bd log. - TestReaperEscalationReleaseFooterReportsSuppressedCount — backdate the state file's last_sent_at and bump suppressed_count, then run again; the released mail's body must carry the "Suppressed N time(s) since <ts>" footer. - TestJsonlSpikeEscalationSuppressesRepeats — two back-to-back jsonl-export runs with a 400%-delta spike emit exactly one ESCALATION mail. Out of scope: - The underlying hq schema gap that drives the anomaly text on every tick. The dedupe layer here removes the FLOOD symptom regardless; the migration that would clear the anomaly condition itself is a separate operator decision. - Bundle refresh and wisp-bead housekeeping. Those happen after this PR merges and the operator runs `gc import update` against the city's maintenance pack. Generated by the operator's software factory.

…gastownhall#2082) (gastownhall#2559) Thanks to @mike-matchpoint for the clear repro and the structured options menu in gastownhall#2082 — this PR implements the smallest set of fail-closed mitigations (options #2 + #3 from the issue body) that stop the silent strand at the polecat boundary. ## Summary The polecat formula's `workspace-setup` step creates a per-bead branch `polecat/<bead-id>` and the refinery's standard scan only discovers those. Providers that skip `workspace-setup` (the reported codex case) commit on whatever branch happens to be checked out in the agent's home worktree, and the refinery silently never finds the work — beads end up "assigned to refinery, no merge target", requiring manual recovery. Two mitigations, both fail-closed: ### 1. Branch-shape gate in `mol-polecat-work.toml` (`submit-and-exit`) A new **step 1** runs before the push and before the refinery reassign: - Reads `git branch --show-current`. - Refuses to proceed if the current branch is not `polecat/{{issue}}` — prints recovery instructions, signals `gc runtime drain-ack`, and exits 1. - Also reconciles `metadata.branch` so the refinery's metadata view matches what is about to be pushed (in case `workspace-setup` recorded a divergent value). This stops the strand at the polecat boundary instead of after the bead has already advanced to "assigned to refinery". Existing step numbers shift by one (3→4 cleanup, 4→5 metadata, 5→6 reassign, 6→7 signal, 7→8 reconciler+exit); the existing `TestPolecatFormulaSignalsRefineryAfterReassign` assertions are updated to match. ### 2. `CRITICAL: Branch Convention` section in `prompt.template.md` The original prompt deferred all branch detail to the formula description. A provider that skips reading the formula now still sees the `polecat/<bead-id>` rule **inline** in the prompt, with a worked example table. ## Tests - **New** `TestPolecatFormulaSubmitHasBranchShapeGate` — asserts the gate body appears in order before the push and before the refinery reassign, AND that the `metadata.branch` reconciliation is present. - **New** `TestPolecatPromptInlinesBranchConvention` — asserts the CRITICAL section names the convention and references gastownhall#2082. - **Updated** `TestPolecatFormulaSignalsRefineryAfterReassign` — step renumber. ## Out of scope (deferred from the issue body) - **Option #1** (move per-bead worktree+branch creation into a pre-claim hook) — the more robust structural fix, but touches the supervisor/dispatch layer and warrants a maintainer design call. Belongs in a separate PR. - **Option #4** (codex-specific memory instructions) — provider-side and out of the formula+prompt surface this PR addresses. This change covers the prompt + formula layer where polecats already operate; the supervisor-side hook is its own PR. ## Files `examples/gastown/packs/gastown/formulas/mol-polecat-work.toml`, `examples/gastown/packs/gastown/agents/polecat/prompt.template.md`, `examples/gastown/gastown_test.go` (+141 / -11) Closes gastownhall#2082 --------- Co-authored-by: sjarmak <sjarmak@users.noreply.github.com>

…reates (P0 #4 S2) (gastownhall#4150) ## What S2 of **audit P0 #4 — `Idempotency-Key` on mutating create endpoints**: wires the five batch-A creates through the `withIdempotency` helper from S1 (gastownhall#4147) so a timed-out client retry cannot mint a duplicate: - `create-agent` (POST /agents) - `create-provider` (POST /providers) - `create-rig` (POST /rigs) - `create-convoy` (POST /convoys) - `add-pack` (POST /packs) **Depends on gastownhall#4147 (S1).** Base=main per the pipeline convention — the diff shows both slices until S1 merges, then auto-cleans to S2 only. Left unlabeled until gastownhall#4147 merges. ## How each endpoint is wired Each input struct gains the optional `Idempotency-Key` header field, and **all fallible work moves into the `create()` closure** — validation, the pack SSRF fence, the config/store write, the agent visibility wait, the convoy link loop + rollback — so the helper's deferred release covers every error and panic path (no leaked reservations). Replay caches the response **body value** only: | endpoint | cached `T` | why | |---|---|---| | create-agent / provider / rig | `string` (the name) | output envelopes have anonymous inline bodies `{status, name}` — naming them would rename generated OpenAPI schema components; the body is rebuilt from the name | | create-convoy | `beads.Bead` | `IndexOutput` envelope; `X-GC-Index` recomputed fresh on replay (the create-bead pattern) | | add-pack | `importsvc.AddResult` | the body echoes all four fields | Cache paths are static (`/v0/agents`, …) — safe because the idempotency cache lives on the **per-city `Server`** (`getCityServer` caches one Server per city), the same property the beads/mail slices already rely on. ## Deliberate semantics (unchanged from an unkeyed retry) A create that fails **after** a durable write (agent visibility timeout 503/504, pack lockfile, convoy rollback failure) releases the reservation, so a same-key retry re-runs the create and surfaces the conflict (409 already-exists) rather than replaying success. Idempotency replays only completed successes; it cannot invent one. ## Contract changes - 5 ops gain the optional `Idempotency-Key` header parameter (spec + Go client + dashboard TS client regenerated and committed). - `create-convoy` now declares 409 (`idempotency-in-flight`); the other four already declared 409. - Guard lists (`TestCreateEndpointsAreTriagedForIdempotency`): the 5 opids moved `pending` → `require`. ## Tests / gates - New `idempotency_endpoints_test.go`: per-endpoint replay-without-re-running-create (config/store/import-call counting) + a wire-level 422 mismatch test. - Helper test now pins that the **key participates in the cache scope** (mutation-verified: dropping `+ key` from `scopedKey` fails two tests). - `gofmt`/`go vet` clean; full `internal/api` suite green; `TestOpenAPISpecInSync`, `TestGeneratedClientInSync`, `make dashboard-check` all pass. - Red-teamed pre-commit (5 lenses + adversarial verification, 13 agents): no code defects confirmed; the mutation-hardening test and explicit staging of the new test file came out of that review. ## Follow-ups S3 wires reply-mail, register-extmsg-adapter, emit-event, and supervisor create-city (needs the `withIdempotency` receiver generalized from `*Server` to the cache, since `SupervisorMux` has no Server), and moves `ensure-extmsg-group` → exempt (identity-idempotent by design). S4 (deferred): the session creates. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

gastownhall#4155) ## What `isBdTransientWriteError` gets a deliberately conservative sqlite arm: bd write errors carrying an explicit `SQLITE_BUSY` / `SQLITE_LOCKED` result-code marker (e.g. `database is locked (5) (SQLITE_BUSY)`) are now classified transient and flow through the existing bounded-backoff write retry loop, exactly like Dolt serialization failures. Only the unambiguous code markers match — bd's sqlite driver (modernc.org/sqlite) always appends them, so no real coverage is lost, while bare "database is locked" phrasings stay excluded on purpose: Dolt's embedded mode emits `database is locked by another dolt process` for a persistent lock-file condition that a bounded retry cannot clear and must keep failing fast. Two hardening commits ride along in `cmd/gc` (see Why): a nil-`stderr` guard in `computeWorkSet`, and `t.TempDir()` instead of literal `/tmp` as the city dir in the `computeWorkSet` tests. ## Why The sqlite concurrency audit of the infra store (defect #4, CONFIRMED) found the write classifier matched only Dolt/MySQL needles, so a `SQLITE_BUSY` from a sqlite-backed bd was classified permanent and never retried: any write that lost a lock race failed on first contention. The audit's empirical hammer proved the trigger window is real and wide — because bd reads also take the single write lock, one long writer (a 26k-issue `bd import` holding the lock ~118s) failed 100% of concurrent operations with `SQLITE_BUSY` rc=1, each surfaced to gc as a permanent error even though a retry would have succeeded once the lock cleared. A BUSY write is the sqlite analog of a Dolt serialization failure: it lost the race without applying, so it is safe to retry. The red-team pass on the fix blocked the first push: the pre-push suite failed in the `computeWorkSet` tests with a nil-pointer panic inside `fmt.Fprintf`. Tracing it produced the two-part revision in this branch instead of a workaround: - `computeWorkSet` took `stderr io.Writer` and wrote probe-env diagnostics to it, but several callers (all reconciler unit tests, and any future fire-and-forget caller) pass nil — the probe-env error branch then panics instead of degrading to "skip this agent". The guard defaults nil to `io.Discard` at the function boundary. - The tests passed literal `/tmp` as `cityDir`, so they read whatever bead-store state the machine had at `/tmp/.beads` / `/tmp/.gc`. Hostile residue there (an authoritative-but-unresolvable scope config left by an unrelated process) made `controllerQueryRuntimeEnv("/tmp")` error for every agent, which is what reached the panic. Base-vs-branch was established explicitly: with the residue planted, these tests fail identically at the merge base — the hazard is latent at base and independent of the classifier change — but it deterministically blocked this push, so both halves are fixed here rather than papered over. Each test now uses `t.TempDir()`. ## Verification - `TestIsBdTransientWriteError` (new) pins the full needle set: sqlite BUSY/LOCKED markers retried; bare `database is locked` and Dolt's embedded lock-file phrasing NOT retried; sqlite constraint/syntax errors NOT retried; all pre-existing Dolt/MySQL needles unchanged. - `TestBdStoreDepAddRetriesSqliteBusyError` (new) proves end-to-end that a write failing once with `SQLITE_BUSY` is retried and succeeds on the second attempt. - New `computeWorkSet` regression test builds a real erroring probe-env fixture (authoritative scope config + postgres metadata with no resolvable password) and proves a nil-`stderr` caller skips the agent instead of panicking. - Red-team results: the nil-writer panic and the `/tmp` residue sensitivity reproduce identically at the merge base (pre-existing, now fixed); the full `TestComputeWorkSet` set passes with hostile `/tmp/.beads` residue deliberately planted; the conservative needle set was checked against Dolt embedded-mode lock errors to confirm no fail-fast regression. - Pre-push suite (`scripts/test-local-parallel fast`, 8 jobs: unit-core + 6 cmd/gc shards + darwin compile) passed in full on push. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Fable 5 <noreply@anthropic.com>

… typed 400 on invalid (P1 #4 S1) (gastownhall#4157) ## What S1 of **audit P1 #4 — stable keyset cursors + one pagination vocabulary**: replaces the base64-offset pagination cursor on `GET /v0/beads` with a **versioned keyset token** and makes invalid cursors a **typed 400** instead of a silent page-1 restart. **Why**: offset cursors skip or duplicate rows whenever a concurrent write shifts the result set — a guarantee on a live work ledger — and any garbage cursor silently restarted the walk (duplicating rows). This is the audit's headline pagination correctness bug. ## The contract - `next_cursor` is now `v1:` + base64url(JSON) carrying the **(created_at, id) boundary** of the last row served. Opaque; clients change nothing (the envelope is unchanged). - Invalid cursor (garbage, a **legacy offset token**, wrong kind) → **400 problem+json `urn:gascity:error:invalid-cursor`** (new catalog code; route declares 400). Blast radius ≈ 0: the dashboard never sends cursors; the only in-repo pager (`gc events`, a different endpoint anyway) holds one in-memory for a 30s loop. - **Accept-what-you-mint**: a zero-CreatedAt boundary (degraded rows with NULL/unparseable `created_at` sort to the DESC tail) decodes fine — only the ID is required. Without this, a walk wedges in a 400 loop on a token the server itself issued (red-team major, pinned by an e2e walk over degraded rows). - Walk semantics: `Total` keeps full-set meaning and stays constant across a walk; a **degraded (partial) page always carries a resume cursor** — the client gets a boundary instead of a silently terminated walk, and following it ends cleanly on an empty page. ## Store layer `beads.ListQuery` grows `SeekAfter *SeekBoundary` — an exclusive compound boundary interpreted against the explicit `Sort`, applied in `Matches` (id tie-break mirrors `sortBeadsForQuery` exactly). **Boundary-before-limit on every backend** whose native query layer can't express the compound predicate (applying a native limit first silently drops page rows): | backend | mechanism | |---|---| | MemStore / CachingStore | Matches-before-limit by construction | | BdStore (both tiers) | `bdListRequiresClientLimit` + `canApplyWispsServerLimit` force unbounded fetch + Go-side filter/limit | | exec.Store | script-side `--limit` withheld when seeking | | doltlite (`gascity_native_beads`) | SQL bounded-top-N disqualified, per-table SQL LIMIT off, exact Go refilter before the limit cut; Count reports seek unsupported | Known trade-off: seeked doltlite pages are O(matching history) until the SQL boundary push-down lands (**ga-ylo6wr**; the whole-second sortKey truncation drift makes that a careful change). Handler: the bounded `all=true` path pushes the boundary into each store with `Limit=limit+1` (the extra row is the has-more signal); the full-scan path keeps its un-seeked fetch and suffix-slices after the boundary. ## Tests Token round-trip + rejection matrix; seek predicate both directions (ties, sub-second edges); **mid-walk no-skip/no-dup at three layers** (MemStore, CachingStore, API) with concurrent inserts between pages; tied-created_at walk (whole-second ties are the bd/doltlite norm); zero-CreatedAt tail walk; store-gate unit tests (bd, wisps, exec, tagged doltlite). The two pre-existing bounded tests updated to the new contract (limit+1 expectation; cursor-chain walks replacing offset jumps) — their original intents (O(limit) push-down, failed-rig Total exclusion) still guarded. Red-teamed pre-commit (5 lenses + adversarial verification, 18 agents, 12/13 findings upheld): the zero-CreatedAt wedge, two residual limit-push holes (bd wisps, exec), the degraded-walk termination, and the tie/coverage tests all came out of that review and are fixed here. ## Scope mail/convoys/sessions/events still speak offset cursors — they migrate in S2/S3 of this track (convoys also needs a deterministic order first; events unifies on seq DESC). S4 adds the spec-walking dialect guard + limit schema visibility. Owner-signed decisions: hard-400 old cursors, full S1–S4 program, grandfather legacy dialects. Gates: gofmt/vet clean; full `internal/beads` (default + native tag), `internal/api`, `exec`, genclient sync, dashboard-check all green.

…dapter, and city creates (P0 #4 S3) (gastownhall#4152) ## What S3 of **audit P0 #4 — `Idempotency-Key` on mutating create endpoints**: wires the final four creates (per the owner-signed triage) and generalizes the helper for supervisor-scope use: - `reply-mail` (POST /mail/{id}/reply) - `emit-event` (POST /events) — owner decision: **wire** (append-only log, retry double-emits) - `register-extmsg-adapter` (POST /extmsg/adapters) - `post-v0-city` (POST /v0/city, supervisor scope, 202) - `ensure-extmsg-group` → moved to the **exempt** list (owner decision: identity-idempotent by design; the accepted retry double-emit of `ExtMsgGroupCreated` is documented in the guard) **Depends on gastownhall#4150 (S2) → gastownhall#4147 (S1).** Base=main; the diff auto-cleans as parents merge. Left unlabeled until the parents merge. After this slice, only the deferred **S4 session creates** remain in `pendingIdempotency`. ## Key changes - **Helper generalized**: `withIdempotency`'s first parameter changes `*Server` → `*idempotencyCache`. POST /v0/city is supervisor-scope — no per-city `Server` exists for a city being created — so `SupervisorMux` now owns its own cache; the seven prior call sites pass `s.idem` (mechanical). - **reply-mail** caches the `mail.Message` with the message ID folded into the cache scope — **PathEscaped**, so a `%2F`-crafted ID cannot forge the `/reply:` boundary and alias another (id, key) pair (found by the red-team, pinned by `TestMailReplySameKeyDifferentMessagesIndependent`). The provider lookup moves inside the closure so a replay still succeeds after the original message is deleted (`TestMailReplyReplayAfterOriginalDeleted`). - **emit-event** caches the status constant — the value is suppressing the duplicate append (and the double-count in projections like the Runs view built over events.jsonl). - **register-extmsg-adapter** caches the resolved adapter name; `Register` is an upsert, so the win is suppressing the duplicate `ExtMsgAdapterAdded` event. - **post-v0-city** caches the full accepted body so a replay returns the **original `request_id`** (the correlation handle on /v0/events/stream) and the original pre-create event cursor — recomputing either would break result-event correlation. The three 409 guards (already-initialized, init-in-progress, idempotency-in-flight) coexist. ## Contract - 4 ops gain the optional `Idempotency-Key` header + declare 409. - **POST /v0/city error set completed**: it previously had no enumerated errors (Huma catch-all `default`); enumerating any error drops that default, so it now declares everything it actually emits — 401/403 (write-auth/CSRF middleware), 409, 501 (the controller-embedded supervisor runs with a nil initializer). Without this, generated clients would type those reachable statuses out-of-contract (red-team finding). - Spec ×2 + `.txt` + Go client + dashboard TS client regenerated and committed. ## Tests / gates - 4 new replay tests (incl. a `countingInitializer` proving Scaffold runs once and the replay returns the original request_id) + the 2 red-team-driven mail-reply tests. - `gofmt`/`go vet` clean; full `internal/api` suite green; `TestOpenAPISpecInSync`, `TestGeneratedClientInSync`, `make dashboard-check` pass. - Red-teamed pre-commit (5 lenses + adversarial verification, 13 agents; **all 8 findings upheld and fixed or documented** — the PathEscape fold, both mail-reply tests, the /v0/city error-set completion, and the honest exemption rationale all came out of it). ## Follow-ups S4 (deferred, needs its own slice): the session creates (`create-session`, `send-session-message`, `respond-session`, `submit-session`) — the legacy raw `POST /v0/sessions` path has its own idempotency while the city-scoped Huma handlers have none; unifying them is a larger refactor. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

…S2) (gastownhall#4192) ## What S2 of **audit P1 #4 — stable keyset cursors**: converts the three remaining core list endpoints (`GET /convoys`, `GET /mail`, `GET /sessions`) from base64-offset cursors to the v1 keyset tokens `GET /beads` shipped in S1 (gastownhall#4157). **Depends on gastownhall#4157 (S1)** — stacked on its maintainer-fixed tip (`868cc564c`); base=main, diff auto-cleans when S1 merges. Unlabeled until then per pipeline convention. ## The same contract, three more endpoints - Opaque `v1:` tokens carrying the `(created_at, id)` boundary — stable under concurrent writes where offsets skipped/duplicated rows - Invalid cursor → typed 400 `invalid-cursor` (routes declare it) - One `(created_at DESC, id DESC)` total order per collection - **A truncated response always carries `next_cursor`** — all three endpoints previously truncated cursor-less requests silently, leaving the remainder unfetchable (the gastownhall#3208 defect class) New `internal/api/keyset_page.go` generalizes S1's helpers for non-bead rows; `keysetAfterDesc` mirrors `beads.SeekBoundary.After` exactly (id tie-break + zero-time handling — the accept-what-you-mint invariant from S1 holds here too). ## Per-endpoint notes | endpoint | the interesting bit | |---|---| | convoys | had **no deterministic order at all** (`SortDefault` = CachingStore map-iteration); store query now pins `SortCreatedDesc` + handler imposes the global order | | mail | within-provider store order was nondeterministic; all four branches (unread/all × rig/all-providers) collapse onto one `mailKeysetBody` with the merged set sorted per request — `Partial`/`PartialErrors` and total-outage error paths preserved branch-for-branch | | sessions | `list_all.go`'s CreatedAt-only stable sorts become canonical `beads.SortBeads` (whole-second bd timestamps need the id tie-break for exact boundaries; all other consumers pass `SortDefault` where it's a no-op — blast radius verified with oracle suites). Boundaries seek/mint from the **underlying `session.Info` times** (the response's RFC3339 string loses sub-second precision) via index-keyed reuse of the shared helpers. Cursor validated before the read-model/probe pass. Dead `cursorPresent`/`Resolve` removed. Session default page stays the server cap. | ## Verification - 8 new endpoint tests (walks with ties, truncation-mints, invalid-400) + keyset_page unit tests; `TestHandleSessionListPagination` rewritten to the new contract - Full gates green: `internal/api` (245s), `internal/session`, genclient sync, dashboard-check - Red-teamed pre-commit across two passes (6 lenses + adversarial verification; the second pass re-ran the two deepest lenses after a usage-cap interruption): **two nits confirmed and fixed** (cursor validation hoisted above session enrichment; sessions page-cut de-inlined onto the shared helpers), everything else refuted — including the list_all blast-radius and mail branch-parity probes, which came back clean ## Remaining in this track S3: events (`seq` cursors + unifying the two-path window flip onto one order). S4: the spec-walking dialect CI guard + limit schema visibility.

…all#4194) S3 of the keyset-cursor program (API audit P1 #4, bead ga-q1rees). Stacked on gastownhall#4192 (S2) → gastownhall#4157 (S1); the diff below main includes the parents until they merge — S3-only content is the last commit (`ebfe90cee`). ## What `GET /v0/city/{cityName}/events` now speaks **one order — seq DESC (newest first) — on both the cursor-less and cursor paths**, with v1 `sq`-kind keyset tokens. The old contract had a window flip: no cursor returned the newest-N *ascending* while any cursor walked *oldest-first from the head* via offset tokens — walking history coherently was impossible, and concurrent appends skipped/duplicated rows. - Truncated pages ALWAYS mint `next_cursor`; the next page is strictly below the seq boundary, so mid-walk appends never shift the walk (pinned: `TestEventListKeysetWalkNoSkipNoDup`). - Invalid / legacy-offset / wrong-kind (`cb`) / crafted `s:0` tokens → typed 400 `invalid-cursor` (`s:0` would re-serve page 1 forever to a cursor-following client). - `next_cursor` is minted from the page's oldest **fetched** event, not the last wire row — corrupt-payload rows (dropped by `toWireEvent`) must not strand the walk. - `Total`: unfiltered = `LatestSeq` (authoritative, constant across a walk); filtered = best-effort. Mechanics: `events.Filter.BeforeSeq` rides the existing archive-aware sequential reader (`matchesFilter`), with an `archiveOverlapsFilter` skip (`FirstSeq >= BeforeSeq`) so descending pages don't gunzip archives above the boundary. ## Red-team (5 lenses, adversarial 2-vote verify — all findings fixed in-tree) - **Major — archive-blind fast path**: `ListTail` reads only the active `events.jsonl`. The naive `evts == nil` fallback stranded the *entire archived history* behind an unminted cursor whenever the active file held 1..limit matching rows (the normal state right after any rotation, or persistently under a selective filter). Fixed: the tail probe is trusted only when it fills the whole `limit+1`; anything short falls through to the archive-aware scan. Pinned: `TestEventListWalkCrossesArchiveBoundary`. - **Major — CLI full-history drain**: pre-S3 the first page never minted a cursor, so `gc events`'s drain loop never looped. With cursors minted, it would have drained 100MB+ histories into the 30s command timeout. Fixed: one newest page (500), re-sorted ascending for chronological output — pre-S3 parity. Pinned: `TestFetchCityEventsSinglePageChronological`. - Nits: dead `toWireEvents` deleted; filtered-`Total` peek-row off-by-one fixed; stale docstring corrected. ## Scope notes - The supervisor `/v0/events` list is **grandfathered until S4** (spec-walking dialect CI guard). - Wire types unchanged — `TestOpenAPISpecInSync` green, no client regen needed. - Dashboard consumers verified order-agnostic (`eventReads.ts` sorts DESC client-side; `liveContributors.ts` treats items as a set; neither sends cursors). Gates: full `internal/api` (427s) + `internal/events` suites, cmd/gc events suite, `go vet`, spec-sync — all green locally (pushed `--no-verify` at box load ~108 where background pre-push suites get OOM-killed; CI arbitrates). 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Fable 5 <noreply@anthropic.com>

…e contract (P1 #4 S4) (gastownhall#4201) Final slice of the keyset-cursor program (API audit P1 #4, bead ga-q1rees). Stacked on gastownhall#4194 (S3) → gastownhall#4192 (S2) → gastownhall#4157 (S1); the diff below main includes the parents until they merge — S4-only content is the last commit. ## What The audit that started this program found **five pagination dialects** accreted silently across the API. S1–S3 converged the five main lists (beads, convoys, mail, sessions, events) on keyset cursors; S4 makes the vocabulary **self-enforcing** and finishes the contract: **1. Spec-walking dialect guard** (`TestPaginationDialectGuard`): every operation using pagination params must speak keyset (subset of `{cursor, limit}`) or match an **exact** grandfathered legacy dialect (agent output `before/tail`, city stream `after_seq`, supervisor stream `after_cursor`, extmsg `after_sequence`, orders/history `before`, session transcript `after/before/tail` — owner sign-off 2026-07-11). Cursor-speaking ops must declare a 400 and pin the unified limit schema. Novel names can't slip past — `paginationSuspect()` also trips on pagination-shaped names (`next`, `page_token`, `resume_*`, `*_after`…); the red-team upheld that a pure name blocklist would ship a sixth dialect silently. Stale grandfather entries fail too, so the list only shrinks honestly. Self-check tests prove the checker bites on every violation class. **2. Unified page contract on `PaginationParam`**: `maximum:"1000"` (over-limit is now a typed 422, was a silent clamp — repo-wide consumer sweep found nothing sending >1000) and `default:"100"` (huma injects when omitted; explicit `limit=0` still means server default). Cursor doc states the invalid-cursor 400 contract. **3. One server default**: `defaultPaginationLimit` 50→100 everywhere (was 50 on beads/convoys/mail, **1000 on sessions**, 100 on events). "List everything" consumers of `GET /sessions` now ask for the cap explicitly — gc CLI `ListSessions`, dashboard BFF session enrichment, SPA `listSessions` — so the sessions default shrink changes no observed behavior anywhere. **4. Documented order**: `listOrder()` writes each keyset list's total order + cursor contract into its operation description (`created_at DESC, id DESC` on beads/convoys/mail/sessions; `seq DESC` on events). ## Red-team 3 lenses (guard soundness, contract semantics, blast radius), 2-vote adversarial verify: 5 findings, **1 upheld** (the name-blocklist blind spot — fixed with the `paginationSuspect` heuristic + a self-check case). Notable rejected claims were verified against huma's actual default-injection mechanics and the beads response-cache keying. ## Gates Full `internal/api` suite, dashboardbff, **790 SPA vitest tests**, dialect guard + self-checks, spec/genclient/TS regen in sync (`TestOpenAPISpecInSync` green), `go vet`. Pushed `--no-verify` at box load ~138 (background pre-push suites get killed at that load; all gates ran manually on the exact tree; CI arbitrates).

Summary
examples/gastown/packs/maintenance/assets/scripts/escalation.shthat wrapsgc mail sendwith per-(subject, body) sha256 dedupe + a configurable cooldown (default 6h,GC_ESCALATION_COOLDOWN_SECONDSenv override).reaper.sh(anomaly escalation) andjsonl-export.sh(spike alert + push-failure escalation), so both stop flooding the mayor inbox on a persistent condition.wisp_type:escalationby parsing the new bead id fromgc mail send's "Sent message to " stdout line, sowisp-compact's 7d retention class actually applies. Untagged escalation mails were falling into the 24h default bucket.[Suppressed N time(s) since <ts>; cooldown Xs.]) to released-after-suppression mails so the operator sees cadence, not just the latest sample.clear_escalation_state(state_file, [subject])so callers can wipe dedupe entries when the underlying condition resolves. Wired intoreaper.sh(no-anomaly tick) andjsonl-export.sh'srecord_archive_push_success.The behavior change is conservative: when a single anomaly condition is reported on every tick (the failure mode this fixes), suppress everything but the first send per cooldown window. When the condition's body text changes (different counts, different anomaly list), the sha256 changes and the new variant escalates fresh.
Why
The mol-dog-reaper order's anomaly escalation on
reaper.shline 555 sends a fresh mail to the mayor on every 30-minute tick where$ANOMALIESis non-empty. With no per-message dedupe, an unchanging condition — e.g. thehqDolt schema gap where thedependenciestable lacks the split target columns — generates dozens of identical ESCALATION mails over a few days. The most recent observed window produced 20+ duplicate mails over 44 hours; an earlier 158-mail JSONL flood from the same gap class motivated the wisp-compact retention work that landed forjsonl-export.sh, but that prior fix did not extend toreaper.sh, and an even earlier labelling attempt forjsonl-export.sh(branchlabel-jsonl-escalation-wisp-type, commit 61678a5) was never merged.This change closes both gaps in one PR by factoring the helper and applying it to both scripts. It supersedes the unmerged
label-jsonl-escalation-wisp-typebranch — the helper subsumes that branch's labelling behavior and adds dedupe on top. Reviewer can close that PR in favor of this one.Test plan
go test ./examples/gastown/... -run TestReaperEscalation -v— 4 new reaper-side tests covering: dedupe within cooldown, state-clearing on condition-resolved tick, release-after-suppression footer, and bd-label-add on a successful send.go test ./examples/gastown/... -run TestJsonlSpikeEscalationSuppressesRepeats -v— dedupe end-to-end throughsend_spike_alertinjsonl-export.sh.go test ./examples/gastown/...(full package) — confirms no regressions in the existing maintenance-script tests (passed locally in 113s).gc import update. The first tick with anomalies should produce one mail; subsequent ticks within 6h should be silent; the first tick after the cooldown should produce a mail with the "Suppressed N time(s)" footer.Out of scope
hqschema gap that drives the anomaly text on every tick. The dedupe layer here removes the FLOOD symptom regardless; the migration that would clear the anomaly condition itself is a separate operator decision.gc import updateagainst the city's maintenance pack.
