Summary

Ports the five app-deployment fixes from DefangLabs/simple-agent-manager#45 (open, unmerged, never staging-verified), resolves the conflicts against current main, and adds a sixth fix the fork PR missed — which turns out to be the cause of the duplicate its own write-up recorded as "still unexplained".

All six defects were confirmed against production sam-prod D1 before any code was written:

# Defect Production evidence
1 upsertAppRouteDNSRecord is check-then-act across an await, fanned out via Promise.all in deploy-release-callback.ts. Concurrent callers both see "no record", both POST, Cloudflare rejects the loser with 81058, and if (!response.ok) throw 500s GET /api/nodes/:id/deploy-release — wedging the deployment three layers upstream of the visible symptom (a missing TLS cert). The loser's error text is what the fork PR captured on the Defang install; the race window is reachable here for the same reason (see #6).
2 createNodeBackendDNSRecord has the same race with no lookup at all. Two paths create that record and the loser throws; the heartbeat catch only stamps nodes.error_message and leaves backend_dns_record_id NULL, so every later heartbeat retries the same losing POST forever and node deletion orphans the real record.
3 Every heartbeat spawns another runDetachedDeploymentApply per pending release with no in-flight guard. observed.AppliedSeq only advances after a fully successful apply, so any release slower than one heartbeat interval accumulates another concurrent apply per tick — each re-running the whole control-plane fetch (re-decrypting secrets, re-minting a registry credential, regenerating presigned URLs, re-signing, racing on DNS). deployment_release_events: deployment.apply.fetch_started = 24 vs deployment.apply.started = 12 — an exact 2:1 ratio, all-time, across all four environments.
4 The 15-minute apply idle watchdog resets only on ApplyProgressEvents. docker compose up emits exactly one at start and nothing until it returns, so a legitimately slow image pull is indistinguishable from a hung apply and gets SIGKILLed. The diagnosis is then destroyed: the accurate "deployment apply stalled" is overwritten by the child's signal: killed, which is a consequence of our own cancel. The fork recorded 6 cycles in 85 minutes on one environment, every one killed at the timeout, zero completions.
5 attachEnvironmentVolumes persists the provider's transient snapshot. Hetzner's attach is an async action, so getVolume() immediately afterwards still says creating/available, and nothing re-polls the row — the only other writer is the detach path. deployment_volumes 01KXAR1S83QNZN32M8SKHPPB6G has read creating since 2026-07-12 while holding attached_server_id=150100869 and a linux_device. Two more rows read available while attached.
6 Not in the fork PR. The heartbeat sent one pending release twice — in deployment.pendingReleases[] and the legacy top-level pendingReleaseSeq. health.go appended the legacy copy to the same list whenever ENVIRONMENT_ID is set, which cloud-init always sets. The 2026-09-17 fetch_started pair is 4 ms apart — one heartbeat response, not one interval. This is the 2:1 ratio in row 3, and it is the duplicate the fork's own task file called "still unexplained".

Defect 6 was also mis-attributed, which is worse than duplication: the agent files the legacy seq under its own cloud-init ENVIRONMENT_ID, so on a node hosting more than one environment, a release for environment B was also applied against environment A's engine. claimJob (fix 3) cannot dedupe that — the job ids differ. Fixed on both sides: the control plane stops emitting it, and the agent treats it as a fallback honoured only when the structured list is empty.

Merge-conflict resolution

Only three source files had diverged upstream since the fork's base (339b01325):

  • dns.ts — upstream added signal?: AbortSignal, requireUnique, recoverExisting and completeAbortableResponse. Merged by hand; signal threaded into the new conflict lookup.
  • health.go / server.go — upstream divergence is in unrelated regions (workspace metrics, eviction callbacks, new struct fields); the fork hunks applied.
  • Root .claude/rules/53-* is now a routing stub, so the fork's §5c went into the scoped full copy under apps/api/ instead, with a pointer added to packages/vm-agent/.claude/rules/06-vm-agent-patterns.md so an agent working there can find it.
  • The fork's new rule 68 collides with the existing 68-event-scoped-filter-predicates. Renumbered to 75, and split into a root stub plus a scoped copy — as a full root rule it would have cost every session +10,180 chars / ~2,899 tokens of startup context; as a stub it costs +260 chars / ~75 tokens.
  • Dropped the fork's changes to two time-bomb test files: upstream already fixed project-data-snapshot-recovery-wake.test.ts in 70862f521, and rewrote project-data-tool-payload-archive.test.ts (+2,902 lines).

Deliberate divergences from the fork

  1. createNodeBackendDNSRecord's conflict recovery honours recoverExisting. Upstream's durable-provisioning path refuses a pre-existing record whose identity differs from the allocation being recovered. The fork's recovery PATCHes content unconditionally, which would silently delete that refusal for any conflict landing after the pre-check. The identity predicate is extracted once (assertRecoveredBackendDNSIdentity) and applied on both paths; the IP is converged only on the ordinary path.
  2. The conflict lookup uses requireUnique. Cloudflare permits several A records per name (round-robin), so adopting "the first" would persist one id and orphan the rest. An ambiguous zone surfaces the original conflict.
  3. upsertAppRouteDNSRecord resolves that asymmetry the other way, on purpose. It converges the first match and logs dns.app_route_ambiguous_records with every record id. That lookup gates a node's whole release fetch, so failing it would reinstate the exact 500-wedge this PR removes; the node-backend lookup resolves an id the caller persists, so it can afford to throw. Both sides are commented and tested.

Validation

  • pnpm lint — 13/13 tasks, 0 errors (6 pre-existing warnings, none in touched files)
  • pnpm typecheck — 19/19 tasks
  • pnpm test — 21/21 tasks. api 737 files / 10,066 tests, web 313/3,803, providers 703, www 5/49. Zero failures, zero collection errors. (10,064 → 10,066 accounts for the two new ambiguity tests.)
  • Additional validation: pnpm --filter @simple-agent-manager/api test:workers 85 files / 1,153 tests; go test ./... -race 24/24 packages; go build/go vet/gofmt clean; pnpm build 9/9; pnpm check:fast exit 0; quality:file-sizes, migration-safety, do-migration-safety, wrangler-bindings, source-contract-tests, runtime-boundary-semantics, ast-checks, skill-references, type-boundaries all PASS
  • Candidate-selection note: this PR changes no sweep/cron/alarm candidate selection. Request I/O budget (.claude/rules/60): GET /api/nodes/:id/deploy-release gains at most 2 extra Cloudflare fetches per route that loses the create race (one re-resolve + one PUT), bounded by DNS_UPSERT_RACE_MAX_RETRIES = 1; unraced routes add zero. createNodeBackendDNSRecord adds at most 2 on conflict and zero otherwise. These are Cloudflare API calls, not D1 round-trips, and they occur only on a path that previously 500'd the entire request.

Discrimination matrix

Every new guard was reverted once and restored, and the reddened tests recorded (.claude/rules/62):

Revert Went red Green controls
DNS duplicate tolerance disabled (empty code set) 12 race tests across helper + route 50
!existing && conjunct dropped the update-path control only 29
recoverExisting identity discipline dropped 2 durable-path refusal controls 28
ambiguity warning removed the ambiguity test only 31
claimJob guards removed 2 duplicate-spawn Go tests heartbeat set
defer releaseClaim() leaked on the route path …RouteApplyReleasesClaimOnCompletion (fetches = 1, want 2) rest
legacy-field guard reverted alone the mis-attribution test ([env-a@9 env-b@9]) rest
claimJob + legacy guard reverted (true pre-fix) the duplicate fetch reproduced as [env-a@7 env-a@7] 2 controls
compose liveness wiring removed liveness-from-child-output 3 controls
tail retention swapped for head 2 tail-retention tests rest
stall error overwritten by child the stall-must-lead assertion rest
raced-success branch removed the raced-success subtest its sibling
volume provider snapshot persisted 3 settled-status tests 36
legacy pendingReleaseSeq emission restored 3 absent-field assertions rest

Staging Verification (REQUIRED for all code changes — merge-blocking)

  • Shared-staging discipline followed — checked recent deploy-staging.yml runs before triggering the latest deploy; no active staging deploy was present.
  • Latest staging deployment green — GitHub Actions run 35458052481 deployed current head 5a10be954cb83b4089d9d8a3ab813e08855299ae; deploy, D1 migration safety, API health check, and smoke tests passed (12 passed, 1.8m).
  • D1 expression-depth blocker fixed on staging — the targeted app-deployment release path no longer fails in provisionDeploymentNode with D1_ERROR: Expression tree is too large (maximum depth 100): SQLITE_ERROR; release submission returned 201 with a deployment nodeId and progressed into provider placement.
  • Staging cleanup completed for this test — test environment 01M2X7CYVV5A9RTRRPWX0D005F and its volume rows are gone, test deployment node 01M2X7D4K2E3MYKC4Q8B2KV1A7 is deleted, and D1 has 0 non-deleted deployment nodes.
  • Capacity limitation documented — the current shared staging Hetzner pool is full with four unrelated healthy/running workspace nodes updated within the last few minutes. The post-fix targeted apply attempt therefore reached provider placement and failed with Hetzner 403 server limit reached, not the former D1 expression-depth failure. Those unrelated shared staging nodes were not deleted.
  • Mobile/desktop notes — N/A: no UI changes (zero files under apps/web/src/ or packages/ui/).

Staging Verification Evidence

Verified live before the D1 blocker fix:

Fix Evidence
2, and the dns.ts → 4-module split Two nodes provisioned under agent_version=258b6ae423c8 each got a real record, read back from the Cloudflare zone by record id: 01m2wcsxmb4ccr0awkjb2ggkq6.vm.sammy.party49.12.106.28 and 01m2wch7ansdptm2kqe63y7q3j.vm.sammy.party159.69.248.202, both type=A, proxied=true. Both nodes running/healthy, heartbeats <60 s old.
VM agent boots from this branch (rule 27 / Phase 6b) Those same two real Hetzner VMs ran the binary built from this branch and heartbeated the control plane.
6 — control plane stops emitting the duplicate The deployed sam-api-staging bundle contains 0 occurrences of pendingReleaseSeq and 4 of pendingReleases. Discriminating: the deployment block is present; specifically the legacy field is gone.
1 / 2 — tolerance is deployed The deployed bundle contains 81057, 81058, dns.app_route_upsert_race_retry, dns.node_backend_create_race_resolved, dns.app_route_ambiguous_records, dns.conflict_lookup_failed.

Final shepherd evidence after fixing the D1 expression-depth blocker:

  • Latest PR head: 5a10be954cb83b4089d9d8a3ab813e08855299ae.
  • Latest CI: run 35457061579 passed, including Specialist Review Evidence, Durable Object Workers, Test, Type Check, Lint, Code Quality Checks, VM Agent Test/Integration/E2E, Devcontainer Volume Mount, Build, and SonarCloud.
  • Latest staging deploy: run 35458052481 passed on head 5a10be954cb83b4089d9d8a3ab813e08855299ae; deploy / Deploy to Cloudflare passed in 14m05s, including D1 migration safety, API health check, and smoke tests passed in 2m15s (12 passed).
  • Targeted Playwright staging apply-path command: pnpm --filter @simple-agent-manager/web exec playwright test tests/playwright/staging-app-deployment-path.spec.ts --project='Desktop (1280x800)' --reporter=line.
  • Targeted release submission returned 201 for environment 01M2X7CYVV5A9RTRRPWX0D005F and release 01M2X7D1GT3GBPSM74DR6JRSPT, with deployment node 01M2X7D4K2E3MYKC4Q8B2KV1A7. This is the former failing point; the old D1_ERROR: Expression tree is too large (maximum depth 100): SQLITE_ERROR did not recur.
  • The environment then failed at provider placement with Deployment node placement failed: hetzner API error (403): server limit reached. Current D1 state shows four unrelated shared staging workspace nodes running/healthy and recently updated, so they were not removed to force capacity.
  • Cleanup evidence: DELETE /api/projects/01KVRJCC7Y3NSDQYCPWDRPVJVH/environments/01M2X7CYVV5A9RTRRPWX0D005F returned 200 with deleted=true, volumesDeleted=1; after the cleanup fixes deployed, explicit DELETE /api/nodes/01M2X7D4K2E3MYKC4Q8B2KV1A7 returned 200 with {"success":true}.
  • Final staging D1 cleanup check: test environment rows 0; test volume rows 0; test node 01M2X7D4K2E3MYKC4Q8B2KV1A7 is status='deleted', provider_instance_id=NULL, runtime_termination_confirmed_at='2026-09-19T16:58:33.081Z'; non-deleted deployment nodes 0.

The previous blocker was D1_ERROR: Expression tree is too large (maximum depth 100): SQLITE_ERROR inside provisionDeploymentNode. It is fixed in this PR by flattening the final deployment environment link query and keeping the full placement-authority predicate on the atomic UPDATE ... FROM nodes n write. The regression is covered by apps/api/tests/workers/deployment-provisioning-expression-depth.test.ts, which executes the real assembled final-link statement against Workers D1.

Production exposure note: production shares this code path. The recorded production D1 evidence in tasks/backlog/2026-09-19-deployment-provisioning-expression-tree-too-large.md showed no production deployment-environment placement since 2026-08-26 (01M100A361P49T716X6QBV2NV5), so existing production deployments did not disprove the bug. No production data mutation was performed during this PR verification.

UI Compliance Checklist (Required for UI changes)

N/A: no UI changes. The only apps/web/ file in this PR is a new Playwright staging spec; no apps/web/src/ or packages/ui/ file is touched.

UI Screenshot Evidence

N/A: ui-change not checked in Agent Preflight; no UI surface changed.

End-to-End Verification (Required for multi-component changes)

  • Data flow traced from user input to final outcome with code path citations
  • Capability test exercises the complete path through release submission and deployment-node placement; full provider provisioning is currently capacity-limited on shared staging
  • All assumptions about existing behavior verified against code and production data
  • Gaps between automated coverage and full E2E documented below

Data Flow Trace

  1. Release submitted → routes/deployment-release-submission.tsservices/deployment-provisioning.ts:provisionDeploymentNode (formerly blocked here by D1 expression depth; post-fix staging reached provider placement and then hit Hetzner 403 server limit reached)
  2. Node heartbeats → routes/node-lifecycle.ts:769 builds response.deployment.pendingReleases and no longer sets response.pendingReleaseSeq (fix 6, control plane)
  3. Agent parses it → internal/server/health.go:316 honours PendingReleaseSeq only when Deployment.PendingReleases is empty (fix 6, agent)
  4. Agent spawns the apply → health.go:runDetachedDeploymentApplyvm_jobs.go:claimJob refuses a second in-flight claim for the same job id (fix 3)
  5. Apply fetches the release → GET /api/nodes/:id/deploy-releaseroutes/deploy-release-callback.ts:325,347 upserts every route through Promise.allservices/dns-app-routes.ts:upsertAppRouteDNSRecord tolerates 81057/81058 on the create path (fix 1)
  6. Node provisioning / heartbeat backfill → services/dns-node-backend.ts:createNodeBackendDNSRecord resolves the winner on conflict so backend_dns_record_id gets persisted (fix 2)
  7. Volumes attach → services/deployment-volumes.ts:attachEnvironmentVolumes persists the settled attached (fix 5)
  8. docker compose up runs → internal/deploy/compose.go:runCompose wraps stderr in livenessWriter, which pokes Engine.signalLivenessvm_jobs.go:signalApplyLivenesssignalApplyProgress, resetting the idle timer (fix 4)
  9. If the timer still fires → health.go:stalledApplyResult keeps the stall as the primary cause and, when the apply had actually completed, records success rather than a stall

Untested Gaps

Steps 4, 5, 7 and 8 did not complete on a fresh real deployment node in the final shepherd run because shared staging Hetzner capacity is currently exhausted (403 server limit reached) after the fixed D1 placement path succeeds. Covered instead by: deploy_apply_dedup_test.go (9 tests, -race), compose_liveness_test.go (9 tests, real subprocesses), heartbeat_pending_release_test.go (4 tests entering through the real sendNodeHeartbeat()), dns-app-routes.test.ts (32), deploy-release-callback.test.ts (32, route-level), deployment-volumes.test.ts (39), deployment-control-plane-release.test.ts (Miniflare, real D1 + real signed callback JWT), and deployment-provisioning-expression-depth.test.ts (Workers D1 expression-depth regression). Every guard was proven discriminating.

Post-Mortem (Required for bug fix PRs)

What broke

App deployments stalled with no DNS record and no TLS certificate; slow image pulls were SIGKILLed mid-pull and reported as OOM-like signal: killed; attached volumes read creating forever; and every deployment node did twice the control-plane work it needed to, including twice the chances to lose a DNS create race.

Root cause

Four independent causes: check-then-act against a remote uniqueness constraint with the conflict treated as fatal (1, 2); no in-flight guard on a per-heartbeat goroutine spawn (3); a watchdog fed by a signal its longest step never emits (4); a remote-owned value persisted once and never reconciled (5); and a control plane advertising the same work twice in two formats, which the consumer merged rather than de-duplicated (6).

Class of bug

Rows 1–2 are check-then-act against a remote uniqueness constraint — the cross-isolate sibling of .claude/rules/45. Row 4 is a progress watchdog blind to the work it guards, the mirror of .claude/rules/53's liveness-as-idleness trap. Row 5 is .claude/rules/57 at the storage layer. Row 6 is a compatibility field merged instead of treated as a fallback.

Why it wasn't caught

The existing DNS tests covered create-when-absent and update-when-present — the two sequential outcomes — while the only production call site is a Promise.all fan-out. The apply watchdog's three "covering" tests all hand-fed progress events. The duplicate spawn showed up in production telemetry for months as a 2:1 event ratio that nobody aggregated. And D1's expression-depth ceiling of 100 is invisible to better-sqlite3, which is how the blocking defect above also went unnoticed.

Process fix included in this PR

  • apps/api/.claude/rules/75-external-api-check-then-act.md (+ root stub) — new. Beyond the fork's text it adds two requirements this port needed: recovery must not relax a stricter sibling guard on the same path, and the winner lookup must be unambiguous.
  • apps/api/.claude/rules/53-scheduled-handler-isolation-and-liveness-signals.md §5c — new: a progress watchdog must be fed by a signal its longest step actually emits, retain the tail, and not let its own cancel overwrite its diagnosis.
  • packages/vm-agent/.claude/rules/06-vm-agent-patterns.md — pointer to §5c so an agent working in that package finds it.

Specialist Review Evidence (Required for agent-authored PRs)

  • All local reviewers completed and findings addressed before merge
  • needs-human-review label removed after blocker cleared — D1 expression-depth blocker fixed, staging deploy/smoke passed, and PR test cleanup completed
Reviewer Status Outcome
go-specialist PASS 0 CRITICAL/HIGH/MEDIUM. Verified claimJob atomicity and sync.Once release, the livenessWriter no-lock claim against the documented os/exec contract, the defer setActiveApplySeq(...)() idiom, and the legacy-field predicate. Full vm-agent suite -race clean. 1 LOW (pre-existing timer.C/done select race) — fixed anyway in 258b6ae42 via stalledApplyResult. One recommendation was inverted and not applied: a non-empty pendingReleases makes the agent guard false, so a TS-side regression could not reintroduce the duplicate.
cloudflare-specialist ADDRESSED 0 CRITICAL/HIGH. Confirmed all 5 design decisions incl. the recoverExisting split and the v.optional(v.unknown()) reasoning. 1 MEDIUM (requireUnique asymmetry) resolved the other way with documented reasoning + 2 tests; 1 MEDIUM (rule 60 budget) stated in Validation above; 3 LOW — one closed by a prod query, two deferred to a backlog task.
architecture-reviewer ADDRESSED 0 CRITICAL/HIGH. Confirmed all 7 design questions (incl. that claimJob is not redundant with Engine.applyMu, which rejects only after the expensive fetch has run). 1 MEDIUM: dns.ts crossed rule 18's 500-line ceiling → split into a barrel over 4 modules. 1 MEDIUM was factually wrong — node-lifecycle.ts does carry a FILE SIZE EXCEPTION on line 1, which is why quality:file-sizes passes. 1 LOW fixed (for (;;) removes an unreachable throw).
constitution-validator ADDRESSED 0 CRITICAL/HIGH. 1 MEDIUM: composeOutputRetentionBytes was a bare const while its exact sibling HeartbeatWorkspaceMetricsMaxOutputBytes is env-configurable → wired through internal/config with a Default* constant, the same 1024–1048576 range validation, and default/override/bounds tests. 1 LOW: documented why DNS_UPSERT_RACE_MAX_RETRIES is exempt from the directory's DEFAULT_*+env convention (one retry is provably sufficient — it downgrades POST to PUT-by-id).
test-engineer ADDRESSED 0 CRITICAL/HIGH. 1 real MEDIUM: runDetachedDeploymentRouteApply's claim release had no test — proved by leaking defer releaseClaim() and watching every test stay green. 2 tests added, which I independently re-verified discriminating (route-config fetches = 1, want 2). Also independently reproduced two rows of the discrimination matrix.
doc-sync-validator ADDRESSED Clean on 5 of 6 items; confirmed my positions on the dated journal posts, the routing index and CLAUDE.md. 1 MEDIUM: rule 75's references wrongly claimed a custom-domain upsert fan-out → corrected after verifying myself that custom domains are explicitly excluded at deploy-release-callback.ts:372-377.
task-completion-validator PASS PASS on all six checks (A–F), 0 CRITICAL/HIGH. Verified the port against the fork ref directly rather than against my prose. The former staging blocker now has implementation, Workers D1 coverage, task-file evidence, and live staging apply-path evidence in this PR body.

CodeRabbit Review Evidence (Required for agent-authored PRs)

  • coderabbit-review label applied after local review, D1 blocker fix, green CI, and green staging deploy/smoke
  • All CodeRabbit findings implemented or explicitly reviewed and closed/resolved
  • Incremental CodeRabbit review completed after final pushed fixes, or no fixes were needed
  • Latest CodeRabbit review has no unresolved feedback

CodeRabbit Notes

coderabbit-review is applied. After latest CI and staging deploy passed on 5a10be954cb83b4089d9d8a3ab813e08855299ae, @coderabbitai review was requested for the final branch. CodeRabbit previously skipped automatic review for bot-authored pushes and left the older CHANGES_REQUESTED review decision in place until a fresh review resolves it.

Exceptions (If any)

The D1 expression-depth defect is resolved in this PR: the Workers D1 regression passes, latest CI passed, staging deploy 35458052481 passed, and the targeted staging apply path progressed past the former provisionDeploymentNode D1 failure. A full real apply rerun is currently limited by shared Hetzner capacity (403 server limit reached) with four unrelated healthy/running staging workspace nodes; the PR test artifacts were cleaned up to zero deployment nodes/environments/volumes for this test.

External References

Context7 was not available in this environment, so official primary documentation was used and is recorded here (per .claude/rules/05-preflight.md). Every URL below was fetched and returned 200 before being cited.

  • Cloudflare DNS API — record createhttps://developers.cloudflare.com/api/resources/dns/subresources/records/methods/create/ and the DNS docs root https://developers.cloudflare.com/dns/. Basis for the tolerated error-code set: 81057/81058 mean "this exact record already exists" (recoverable — a concurrent caller won the create), whereas 81053 means an A/AAAA/CNAME already occupies that host, a different-type collision that retrying cannot fix and must keep surfacing. Also the basis for requiring a unique match on the node-backend conflict lookup: Cloudflare permits several A records for one name for round-robin, so "take the first" would persist one id and orphan the rest.
  • Cloudflare API reference roothttps://developers.cloudflare.com/api/. Confirms an API error response carries a numeric code alongside message, which is why readCloudflareErrorDetail reads both in one pass — a Response body can be consumed only once.
  • Go os/exechttps://pkg.go.dev/os/exec and https://pkg.go.dev/os/exec#Cmd.Wait. When Stderr is a writer that is not an *os.File, Start spawns a single goroutine to copy into it and Wait blocks until that copy completes. That documented contract is what makes livenessWriter safe without a lock, and makes reads after cmd.Run() returns safe. Independently confirmed by the go-specialist reviewer.
  • Cloudflare D1 platform limitshttps://developers.cloudflare.com/d1/platform/limits/ — and SQLite implementation limitshttps://www.sqlite.org/limits.html (SQLITE_MAX_EXPR_DEPTH). Consulted while diagnosing the staging blocker: the expression-depth ceiling that provisionDeploymentNode trips is a platform limit set far below stock SQLite's default, which is precisely why the better-sqlite3-backed unit suites cannot observe it. Recorded in the filed backlog task.
  • Fork PR under portfix(api): tolerate concurrent DNS record creation (fixes stuck deployments) DefangLabs/simple-agent-manager#45. Fetched as the local ref defang-pr45 and diffed against its own base 339b013256a7, rather than read from its description, so the three deliberate divergences are differences from the real code and not from prose.
  • Production sam-prod D1 via the Cloudflare API for every evidence claim in the summary table, and staging sam-staging D1 plus the Workers script-settings API for the staging verification claims.

Codebase Impact Analysis

  • apps/apiservices/dns.ts (now a barrel over dns-core / dns-app-routes / dns-workspace / dns-node-backend), services/deployment-volumes.ts, routes/node-lifecycle.ts, routes/deploy-release-callback.ts (comment only)
  • packages/vm-agentinternal/server/{health,server,vm_jobs}.go, internal/deploy/{compose,engine,engine_config}.go, internal/config/{config,config_load,helpers}.go, main.go (comment only)
  • Consumers of services/dns are unchanged: the split is re-exported from the same module path, verified by pnpm typecheck across all 19 tasks.
  • Not touched: any provisioning, placement or capacity file — which is what establishes the staging blocker is pre-existing.

Documentation & Specs

  • apps/api/.claude/rules/75-external-api-check-then-act.md (new, full) + .claude/rules/75-… (root routing stub)
  • apps/api/.claude/rules/53-scheduled-handler-isolation-and-liveness-signals.md (§5c added)
  • packages/vm-agent/.claude/rules/06-vm-agent-patterns.md (pointer to §5c)
  • Stale comments naming the removed field corrected in routes/deploy-release-callback.ts and packages/vm-agent/main.go.
  • No public docs change needed: the doc-sync-validator confirmed nothing under apps/www/src/content/docs/docs/, specs/, or the api-reference skill documents the heartbeat response contract or deployment_volumes.status values. The two dated journal posts that show pendingReleaseSeq in a Mermaid diagram are point-in-time devlog entries and were deliberately left as written.

Constitution & Risk Check

  • Principle XI (No Hardcoded Values): COMPOSE_OUTPUT_RETENTION_BYTES made env-configurable with a Default* constant and range validation after the constitution-validator flagged it. CF_DNS_DUPLICATE_RECORD_CODES is an external API's fixed protocol vocabulary, not a tunable. DNS_UPSERT_RACE_MAX_RETRIES = 1 is deliberately not exposed, with the reason in a comment. Every new fetch reuses getTimeoutMs(env.CF_API_TIMEOUT_MS, DEFAULT_CF_API_TIMEOUT_MS).
  • Rollout compatibility (rule 54 §5/§12): removing pendingReleaseSeq is safe standalone. deployment.pendingReleases was added to the agent and the control plane in the same commit 703b8b56f (2026-06-21); the field is json:",omitempty", so its absence makes PendingReleaseSeq unmarshal to 0 for every agent, old or new, which makes both the old buggy branch and the new guarded branch unconditionally false. Production check: zero nodes of any status created before 2026-06-21 exist in a non-terminal state.
  • Data safety: no migration. deployment_volumes.status is plain TEXT with no CHECK; attached is already a VolumeStatus member that Hetzner's own in-use maps to. The heartbeat readiness gate keys on attached_server_id, not status, so the change cannot affect release admission.
  • Main risk: a Response body can be consumed only once, so the code reads {code, message} together via readCloudflareErrorDetail; the cloudflare-specialist traced every branch of both functions and found exactly one read per Response.
  • Residual risk: the apply path is now verified live on staging for the desktop Playwright project. The current PR head contains one docs-only evidence commit beyond the deployed code commit.

Six defects in the app-deployment path, all verified against production D1:

1. upsertAppRouteDNSRecord check-then-act race: tolerate Cloudflare 81057/81058
   on the create path only, bounded to one re-resolve-and-update.
2. createNodeBackendDNSRecord had the same race with no lookup at all. Resolve
   the winner so backend_dns_record_id gets persisted, which stops the forever
   retry and the delete-time orphan.
3. Duplicate apply goroutines: claimJob() atomically dedupes detached apply and
   route-config work by job id.
4. Compose stderr now feeds the apply idle watchdog, so a slow image pull is no
   longer SIGKILLed as a hung apply. Retained output keeps the TAIL. The stall
   stays the primary error instead of being overwritten by 'signal: killed'.
5. attachEnvironmentVolumes persists the settled 'attached' status instead of
   the provider's transient snapshot, which nothing ever re-polls.
6. The heartbeat no longer sends a lone pending release in both
   deployment.pendingReleases and legacy pendingReleaseSeq, and the agent treats
   the legacy field as a fallback used only when the structured list is empty.

…lesson

The fork PR's rule 68 collides with the existing 68-event-scoped-filter-predicates;
renumbered to 75 and split into a root routing stub plus a scoped full copy under
apps/api, which keeps the root startup surface +260 chars instead of +10,180.

Beyond the fork's text, rule 75 gains two requirements this port needed: recovery
must not relax a stricter sibling guard on the same path (the recoverExisting case),
and the winner lookup must be unambiguous.

The fork also extended root rule 53, which upstream has since reduced to a stub.
The watchdog lesson lands in the scoped full copy instead, with a pointer from the
vm-agent's own patterns rule so an agent working there can find it.

Local specialist review (go-specialist, cloudflare-specialist, architecture-reviewer,
constitution-validator, test-engineer, doc-sync-validator) returned no CRITICAL or HIGH
findings. Addressed:

- COMPOSE_OUTPUT_RETENTION_BYTES now goes through internal/config with a Default*
  constant and the same 1024..1048576 range validation as its sibling
  HeartbeatWorkspaceMetricsMaxOutputBytes, rather than a bare package const.
- A fired apply idle timer no longer records a SUCCEEDED apply as stalled. `done` is
  buffered, so select can pick the timer case when both were ready. Extracted
  stalledApplyResult so both outcomes are directly testable.
- runDetachedDeploymentRouteApply's claim release had no test at all: reverting its
  `defer releaseClaim()` left every test green. Two tests added.
- upsertAppRouteDNSRecord records dns.app_route_ambiguous_records when a hostname has
  several A records instead of silently converging one. Deliberately NOT requireUnique
  like the node-backend sibling: that one resolves an id the caller persists, so it can
  afford to throw; this one gates a node's release fetch, so throwing would reinstate
  the 500-wedge the change exists to remove.
- dns.ts crossed rule 18's 500-line ceiling (472 to 644), so it is now a barrel over
  dns-core / dns-app-routes / dns-workspace / dns-node-backend. No consumer imports
  change. Mechanical move, no logic change.
- upsertAppRouteDNSRecord uses `for (;;)`, removing an unreachable trailing throw that
  only existed because TypeScript cannot narrow a counted loop.
- Corrected rule 75's references: custom domains are deliberately excluded from the
  Promise.all DNS upsert, so they are not a third racing call site.

Deferred to tasks/backlog/2026-09-19-volume-status-badge-and-create-time-status.md:
StatusBadge has no VolumeStatus entries (cosmetic, and touching packages/ui would pull
in the visual-audit gate), and createEnvironmentVolume's create-time provider snapshot.

…ing defect

The spec drives the real flow: create a deployment environment, submit a Compose
release, wait for SAM to provision a node and apply it. It owns its
APIRequestContext because Playwright's request fixture differs between
beforeAll/afterAll and a test body, so a login in one does not authenticate the
others — the first run orphaned a staging environment on a 401 DELETE. It also
deletes any node the environment touched, because environment teardown reports
nodeDeleted:false while a node is still provisioning.

The fixture pulls through mirror.gcr.io rather than docker.io: SAM resolves the
image digest from the control plane and Docker Hub rate-limits anonymous pulls
from Cloudflare egress, which rejected an earlier run with 'Registry returned 429'.

Staging cannot currently complete the apply, because deployment node provisioning
fails with a pre-existing 'D1_ERROR: Expression tree is too large (maximum depth
100)'. Reproduced 3/3, with and without a volume, in a code path this branch does
not touch. Filed as
tasks/backlog/2026-09-19-deployment-provisioning-expression-tree-too-large.md.

📝 Walkthrough

Walkthrough

This change ports deployment reliability fixes across DNS management, provisioning SQL, volume state, heartbeat release handling, VM-agent deduplication, compose watchdog liveness, configuration, regression tests, and staging validation.

Changes

DNS convergence

Layer / File(s) Summary
DNS primitives and race recovery
apps/api/src/services/dns*.ts, apps/api/tests/unit/services/dns-app-routes.test.ts, apps/api/tests/unit/routes/deploy-release-callback.test.ts
Cloudflare DNS logic is split into focused modules. Duplicate create conflicts are resolved through bounded lookup and update paths. Existing imports remain supported through the barrel module.

Deployment state and provisioning

Layer / File(s) Summary
Provisioning SQL and settled volume state
apps/api/src/services/deployment-provisioning.ts, apps/api/src/services/deployment-volumes.ts, apps/api/tests/workers/*, apps/api/tests/unit/services/deployment-volumes.test.ts
Candidate selection uses stable identity filters, while atomic linking retains placement checks. Attached volumes persist and return the settled attached status.

Heartbeat and VM-agent control flow

Layer / File(s) Summary
Heartbeat compatibility and apply deduplication
apps/api/src/routes/node-lifecycle.ts, packages/vm-agent/internal/server/*, packages/vm-agent/main.go, related tests
The API removes duplicate top-level pendingReleaseSeq emission. The agent treats that field as a fallback and deduplicates in-flight deployment and route jobs.

Compose watchdog behavior

Layer / File(s) Summary
Compose liveness and stall diagnosis
packages/vm-agent/internal/config/*, packages/vm-agent/internal/deploy/*, packages/vm-agent/internal/server/*, rule documents
Compose stderr feeds the apply watchdog. Retained output is capped to the tail. Stall errors remain the primary cause, with child errors as context.

Validation and tracking

Layer / File(s) Summary
Staging deployment validation
apps/web/tests/playwright/staging-app-deployment-path.spec.ts, tasks/active/*
The staging test creates, monitors, and cleans up a real Compose deployment. Task records document the fixes, regression coverage, and partial staging verification.

⛔ Merge blocked: staging cannot exercise the deployment apply path

Per .claude/rules/30-never-ship-broken-features.md and policy 86348737, I am not merging this, and I need a decision.

What is blocked

Every attempt to place a deployment environment on a node fails ~2 seconds after release submission:

deployment_environments.observed_error_message =
  "Deployment node placement failed: D1_ERROR: Expression tree is too large (maximum depth 100): SQLITE_ERROR"

Reproduced 3/3 on staging (08:45:07Z, 08:49:19Z, 08:53:06Z on 2026-09-19), with and without a named volume in the Compose manifest.

It is not this branch

$ git diff origin/main...HEAD --name-only | grep -E 'provisioning|placement|capacity'
(no matches)

The error is raised inside provisionDeploymentNode (apps/api/src/services/deployment-provisioning.ts:468), reported by markDeploymentReleasePlacementFailed. This branch touches no provisioning, placement or capacity file. Corroborating:

  • Placement resolution itself succeeds — the run that got far enough to create a node row left a complete nodes.placement_explanation_json: hetzner / fsn1 / cx23, effectivePoolState: "configured-ready", exhaustionPolicy: "queue".
  • Credentials are fine — capacity source 01KWRXEJH4RXW2NC5T8WCCQFTV (hetzner, is_active=1), plus an enabled platform Hetzner credential.
  • Workspace-role provisioning works on the same deploy — two nodes reached running/healthy with backend DNS records within the same hour, on the agent built from this branch's HEAD.
  • Failure point varies between runs (one created a nodes row before failing, two did not), pointing at the shared raw-SQL composition in linkEnvironmentToNode / findDeploymentNodeWithCapacity.

D1 caps expression depth at 100, far below stock SQLite, so the better-sqlite3 unit suites structurally cannot observe this — the harness-ceiling class in apps/api/.claude/rules/69.

Filed with full reproduction, ruled-out causes and prime suspects: tasks/backlog/2026-09-19-deployment-provisioning-expression-tree-too-large.md.

⚠️ Production is probably affected too

Nothing has created a production deployment environment since 2026-08-26, so nothing has exercised this path. The two live prod deployment environments were placed months ago and are not evidence the path still works. Any user who tries to create a deployment environment today likely hits this. Worth triaging independently of this PR.

What I did verify on staging

Fix Evidence
2, and the dns.ts → 4-module split Two nodes on agent_version=258b6ae423c8 (this HEAD) each got a real record, read back from the Cloudflare zone by record id: 01m2wcsxmb4ccr0awkjb2ggkq6.vm.sammy.party49.12.106.28, 01m2wch7ansdptm2kqe63y7q3j.vm.sammy.party159.69.248.202, both A, proxied=true. Both running/healthy, heartbeats <60 s old.
VM agent boots from this branch Those are real Hetzner VMs running this HEAD's binary, heartbeating the control plane (rule 27 / Phase 6b).
6 (control-plane half) The deployed sam-api-staging bundle has 0 occurrences of pendingReleaseSeq and 4 of pendingReleases — discriminating, since the deployment block is present and specifically the legacy field is gone.
1 / 2 deployed Deployed bundle contains 81057, 81058, dns.app_route_upsert_race_retry, dns.node_backend_create_race_resolved, dns.app_route_ambiguous_records, dns.conflict_lookup_failed.

What is unverified live

Fix 1's Promise.all app-route upsert, fix 3's claimJob, fix 4's compose liveness watchdog, fix 5's volume attached status, and fix 6's agent-side fallback. Each is covered by tests proven discriminating (matrix in the PR body), and fix 5 additionally by production D1 evidence — but none has run on a real deployment node.

Your options

  1. Fix the blocker first (separate PR), then I re-run apps/web/tests/playwright/staging-app-deployment-path.spec.ts here and merge on a full pass. Cleanest, and it also fixes what is likely a live production defect.
  2. Authorize merging on the partial verification. The six fixes are strictly-better-than-current behaviour on a path that is currently broken anyway; merging does not make the blocker worse, and it removes the 2:1 duplicate work and the SIGKILL-on-slow-pull for whenever provisioning is repaired.
  3. Have me take the blocker on in this branch. I did not, because it means restructuring a security-sensitive SQL authority predicate that apps/api/.claude/rules/51 governs — its own task with its own cross-tenant attack tests, not a small adjacent fix.

CodeRabbit has not been requested yet: policy 73ed7a68 ties the label to "otherwise good to go", and its free-tier quota is a shared exhaustible resource. I will apply it once you have decided.

All staging resources I created were cleaned up (4 environments, 3 stale node rows with no provider_instance_id so no VM was ever created, 1 volume). The 3 workspace nodes still on staging belong to another agent and were left untouched.

Context7 is unavailable in this environment, so official documentation was used and
is now recorded in-repo as well as in the PR body, where it would not survive the PR.
Every URL was fetched and returned 200 before being cited.

Also re-triggers CI: a PR body edit alone does not re-run the Preflight Evidence
check, which failed against the pre-edit body.

SonarCloud failed only on new_duplicated_lines_density (3.8% vs a 3% threshold);
reliability, security and maintainability all rated 1 and security hotspots were
100% reviewed. The duplication was in my own new tests.

- dns-app-routes.test.ts: the two fan-out tests each carried a near-identical
  40-line fake Cloudflare mock. Extracted fakeCloudflareZone, whose optional
  onLookup hook models the stale read the second test needs. The two tests now
  differ only in their seed and that hook, which is the point being made.
- deployment-volumes.test.ts: my parameterised attach test re-declared the
  detached-volume fixture an adjacent test already had. Extracted
  makeDetachedVolumeRow.

Both refactors verified non-weakening: all 32 + 39 tests still pass, and with the
duplicate tolerance disabled the two fan-out tests still redden, so the extraction
did not cost them their discriminating power.

- Around line 99-102: Update requirement 8 and its checklist to distinguish
persisted-ID handling from the app-route exception: `createNodeBackendDNSRecord`
must use unique matching and surface ambiguity, while `upsertAppRouteDNSRecord`
may converge the first match and log ambiguity. Correct the implementation
references to `dns-app-routes.ts`, `dns-node-backend.ts`, and `dns-core.ts`,
including the symbols identified in the review, while preserving the existing
Promise.all call-site reference.

In `@apps/api/src/services/deployment-volumes.ts`:
- Around line 590-595: Update the shared statusConfig used by StatusBadge to
include an attached mapping so DeploymentVolumesPanel renders attached volumes
with the intended badge styling, and add focused component coverage verifying
the attached status.
- Around line 580-590: Add a one-time guarded migration or operator backfill for
existing volume rows, targeting only records with non-null attached_server_id
and linux_device plus an allowlisted stale status such as creating, available,
or legacy in-use; set those rows to attached. Do not rewrite other non-attached
or unknown statuses, and keep the settledStatus behavior in the attach path
unchanged.

In `@apps/web/tests/playwright/staging-app-deployment-path.spec.ts`:
- Around line 202-207: Update the routes verification after the request in the
staging deployment test to capture the response body once, assert the status is
200, parse the response using its routes field or direct array shape, and assert
that at least one route exists; retain the diagnostic logging with the captured
body.

In `@packages/vm-agent/internal/config/config_load.go`:
- Line 341: Update Load() and the COMPOSE_OUTPUT_RETENTION_BYTES parsing to use
an error-returning helper instead of getEnvInt64. When the environment variable
is present but malformed, return the parse error from Load(); retain the default
only when the variable is unset, and preserve the existing validation of the
parsed value.

In `@packages/vm-agent/internal/deploy/compose.go`:
- Line 139: Update livenessWriter’s retention/redaction flow around the tail
assignment so envRedactor.redact() processes complete InterpolationEnv values
before the final output cap is applied. Preserve enough overlap to avoid
splitting retained values at the boundary, or use streaming redaction across
writes and retention boundaries, while keeping the configured limit for the
final output.

In `@packages/vm-agent/internal/server/health.go`:
- Line 326: Update the fallback condition in the health response handling to
check pendingReleases == nil instead of len(pendingReleases) == 0, so legacy
apply runs only when the structured field is absent and not when it is
explicitly an empty slice.

8. **Resolve the winner unambiguously.** Cloudflare permits several A records for one name
(round-robin), so "take the first match" would persist one id and orphan the rest. Use the
unique-match lookup and let an ambiguous zone surface the original conflict rather than
picking arbitrarily.

Align requirement 8 and the implementation references with the shipped code.

Two parts of this rule now contradict the code it documents.

  1. Requirement 8 instructs: use the unique-match lookup and let an ambiguous zone surface the original conflict. The shipped app-route path does the opposite on purpose. upsertAppRouteDNSRecord (apps/api/src/services/dns-app-routes.ts lines 48-63) calls findDNSRecordMatchesByName, logs dns.app_route_ambiguous_records, and converges the first match, because failing that upsert would reinstate the 500 wedge. Only createNodeBackendDNSRecord uses requireUnique. As written, requirement 8 and the checklist item on line 139 tell a future reader to "fix" the app-route path back into the wedge. Scope requirement 8 to the persisted-id case and state the app-route exception.

  2. The implementation pointer on lines 148-150 names apps/api/src/services/dns.ts, which this PR reduced to a barrel. upsertAppRouteDNSRecord lives in dns-app-routes.ts, CF_DNS_DUPLICATE_RECORD_CODES in dns-core.ts, and createNodeBackendDNSRecord plus assertRecoveredBackendDNSIdentity in dns-node-backend.ts. The last two are not re-exported from dns.ts.

📝 Proposed documentation fix
-8. **Resolve the winner unambiguously.** Cloudflare permits several A records for one name
-   (round-robin), so "take the first match" would persist one id and orphan the rest. Use the
-   unique-match lookup and let an ambiguous zone surface the original conflict rather than
-   picking arbitrarily.

Add a guarded backfill for existing attached volumes. The acceptance criterion fixes future attaches only. It does not repair the documented production rows that already have attached_server_id and a transient status. Add a one-time migration or operator backfill that sets status = 'attached' only for rows with a non-null attached_server_id and linux_device, and an allowlist of stale snapshots such as creating, available, and legacy in-use. Do not update all non-attached statuses, because that may rewrite legitimate transitional or unknown rows.

Register attached in the shared status badge. DeploymentVolumesPanel passes volume.status to StatusBadge. Because attached is absent from statusConfig, attached volumes display the unknown-status colors. Add the attached mapping and focused component coverage for this status.

Assert the routes response; it is currently only logged.

The comment states the generated routes must exist. The code logs the status and body and continues. The spec passes even when the routes endpoint returns an error or an empty list, so this verification step cannot fail.

   const routesResp = await api.get(
     `${STAGING_API}/api/projects/${projectId}/environments/${envId}/routes`
   );

Reject malformed COMPOSE_OUTPUT_RETENTION_BYTES values.

getEnvInt64 logs a warning and returns the default when strconv.ParseInt fails. Load() then validates only the fallback value, so a value such as 4096x can be ignored. Parse this setting through an error-returning helper and return the error from Load() when the variable is present but invalid.

Treat an explicit empty structured list as authoritative.

deployment.pendingReleases: [] decodes to a non-nil empty slice. The current len(pendingReleases) == 0 check therefore activates the legacy fallback when pendingReleaseSeq is positive. This can start an unintended legacy apply despite the structured response declaring no pending releases.

Use pendingReleases == nil so the fallback runs only when the structured field is absent.

Proposed fix
