Integrate strict CTO remediation fixes

[simple-agent-manager]

Summary

• Integrates remediation PRs Fix task workspace output branch checkout #1689-Fix atomic bootstrap token redemption #1696 into one mega PR without merging the individual PRs.
• Preserves fixes for task output-branch checkout safety, deploy reusable Wrangler env parity, workers.dev cron fail-closed setup, Worker secret inventory/docs drift, VM-agent shutdown idempotency, configurable Cloudflare container max_instances, ProjectData malformed-row isolation, and atomic bootstrap token redemption.
• Conflict resolved in scripts/quality/deploy-reusable-workflow.test.ts by preserving both the Fix Wrangler sync env parity #1690 shared Wrangler env assertions and the fix(deploy): fail closed on workers.dev setup failure #1691 workers.dev fail-closed executable step tests.

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

• Staging deployment green — run 31084481449, deploy / Deploy to Cloudflare success (2026-08-06)
• Live app verified via Playwright — real browser, token-login auth, 3/3 specs pass
• Existing workflows confirmed working — dashboard, projects, settings, nodes, project chat
• New feature/fix verified on staging — see evidence below
• Infrastructure verification completed (real VM boot) — see "Real VM verification" below
• Mobile and desktop verification notes added for UI changes — N/A: no UI code changes.

Sync with main (done in this PR)

The branch was 19 commits behind main, which had since gained #1649 (Durable Object migration
compatibility). origin/main was merged in (commit 1733035c6), producing three conflicts — all where
#1649 met this bundle's deploy/wrangler fixes:

1. scripts/deploy/sync-wrangler-config.ts (getStaticApiWorkerBindings) — resolved to the UNION:
   main's resolved durableObjectMigrations (NOT the pre-fix: preserve Durable Object migration compatibility #1649 staticBindings.migrations passthrough)
   plus this PR's generated containers from generateContainerBindings.
2. scripts/quality/check-wrangler-bindings.ts — kept this PR's refactor (which adds the Worker
   secret-inventory check) and re-applied main's two wording changes. All 8 checks present in main were
   enumerated and verified still to run.
3. .github/workflows/deploy-reusable.yml — the re-sync step's env was made an exact copy of the
   primary sync step's env (45 entries, parity verified structurally).

A merge-induced regression was found and fixed (commit 8e769c306): the container-max_instances
tests predate generateApiWorkerEnv's 6th parameter and omitted deployedMigrationTag, so it arrived
as undefined. #1649's resolveDurableObjectMigrations fails closed on an unknown deployed tag, so all
three tests threw the migration-reconciliation error instead of the container validation errors under
test. Fixed by passing null — the documented "clean install" value already used by every other call
site — without weakening the #1649 fail-closed guard. 59/59 now pass.

Note: the exact-copy env resolution also repairs a pre-existing drift present on BOTH parents — main's
re-sync step was missing 26 vars relative to its own primary step, and this branch's re-sync step had
independently drifted 10 PLATFORM_FEEDBACK_* vars behind its own primary step.

Staging Verification Evidence

Deployed staging Worker sam-api-staging modified_on = 2026-08-06T08:30:23Z, confirming the merged
branch is the live code. 131 bindings, 20 Durable Object namespaces (matches wrangler.toml's 20 DOs /
20 migrations).

Deploy-path fixes exercised by the deployment itself (from the deploy job log):

Fix	Evidence from the live staging deploy
#1649 compat (my conflict resolution)	API worker "sam-api-staging" migration state: v20 — the deployed tag was read and resolved correctly, not bypassed
#1691 workers.dev fail-closed	Ensuring workers.dev subdomain is initialized: sam.workers.dev → workers.dev subdomain already configured (OK)
#1690 sync env parity	SANDBOX_CONTAINER_MAX_INSTANCES: / VM_AGENT_CONTAINER_MAX_INSTANCES: forwarded through the sync step env
#1692 Worker secret inventory	pnpm quality:wrangler-bindings → "35 configured secrets documented"

Playwright, live staging, real browser (rule 13 token-login auth against api.sammy.party, then
app.sammy.party) — 3/3 specs pass:

• Dashboard, Projects, Settings, Nodes all render. Zero console errors, zero failed/5xx requests, no
  horizontal overflow at 1280x800.
• Project chat page fully renders — waited out the loading state and asserted the absence of
  INTERNAL_ERROR, "Something went wrong", and "Failed to load".
• GET /api/projects/:id/sessions returns 200 across 6 different projects. This is the exact read
  the fix: isolate malformed ProjectData message rows #1695 ProjectData malformed-row isolation fix guards, where a single bad chat_sessions row
  previously threw the whole Durable Object RPC and surfaced as a 500.
• GET /api/projects/:id/tasks returns 200 (task output-branch surface, Fix task workspace output branch checkout #1689).
• Screenshots: .codex/tmp/playwright-screenshots/pr1697-*.png.
• Observation (not a regression): staging session/task reads take 4–6s each; all return 200.

Real VM verification (rule 6b) — PASSED

This PR touches packages/vm-agent/, so rule 6b requires a real VM boot. Completed 2026-08-06 on
staging, on a node provisioned after the staging deploy, so it downloaded the new vm-agent binary
from R2 (rule 27 — staging held 0 nodes beforehand, so no stale-binary reuse was possible).

Node 01KZB5N9GM5HK69717N57A0CES — hetzner / nbg1 / small, IP 195.201.147.109:

Rule 6b step	Result
1. Provision a real VM	Provisioned, reached status=running
2. VM agent heartbeat within 2 min	lastHeartbeatAt=2026-08-06T09:17:36Z, healthStatus=healthy, live metrics (cpu 0.74, mem 14.2%, disk 13.5%)
3. Workspace accessible via ws-* subdomain	GET https://ws-01KZB5VY09177ZBC220KQCBEVQ.sammy.party/health → HTTP 200 {"status":"healthy"}
4. TLS handshake valid	ssl_verify_result=0; DNS resolves to Cloudflare edge; unauth request correctly gated with 401
5. Clean up	Workspace + node deleted; staging verified back to 0 nodes / 0 workspaces

Additional evidence from the live node:

• vm-agent self-reported System provisioning completed in 1m35.963s.
• The control-plane → vm-agent logs endpoint returned real journald output (HTTP 200), proving the
  Worker reaches the agent over Origin CA TLS.
• POST /api/terminal/token issued a workspace token (HTTP 200) — the workspace auth path works.
• Fix atomic bootstrap token redemption #1696 atomic bootstrap token redemption is exercised by this boot: the agent cannot obtain its
  callback credentials or heartbeat without redeeming its bootstrap token, and the heartbeat arrived.
• Make Cloudflare container max_instances configurable #1694 vm-agent shutdown idempotency: teardown produced an orderly
  Port scanner stopped → Removing container → Docker volume removed sequence, and a scan of 200 log
  entries found zero panic / fatal / deadlock / close of closed / nil pointer occurrences.

Capacity note for the record: this step was blocked for ~45 minutes by the shared 10-server Hetzner
limit (403 server limit reached) while SAM's D1 tracked only 9 servers — i.e. at least one
provider-side orphan with no SAM row. Root cause confirmed: listVMs(labels?) is declared on the
Provider interface and implemented by all 8 providers, but is never called anywhere in apps/ or
scripts/, so SAM never enumerates provider-side servers and orphans are invisible to any reaper
that only inspects D1 rows. Passed to the in-flight node-reaping / provider-side-orphan-reconciliation
work. Every probe node created while waiting was deleted immediately; staging ended at zero.

UI Compliance Checklist (Required for UI changes)

• Mobile-first layout verified — N/A: no UI code changes.
• Accessibility checks completed — N/A: no UI code changes.
• Shared UI components used or exception documented — N/A: no UI code changes.
• Playwright visual audit run locally — N/A: no UI code changes.

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 happy path across system boundaries
• All spec/doc assumptions about existing behavior verified against code
• If any gap exists between automated test coverage and full E2E, manual verification steps documented below — staging E2E completed, see evidence above.

Data Flow Trace

• Task output branch: TaskRunner workspace creation now computes checkoutBranch = outputBranch || branch and passes it to VM workspace creation in apps/api/src/durable-objects/task-runner/workspace-steps.ts; task-runner-workspace-branch-dispatch.test.ts verifies generated output branch checkout and base branch behavior.
• Bootstrap token flow: producers call storeBootstrapToken, which registers a hashed token in D1 before KV write; redeemBootstrapToken reserves/claims in bootstrap_token_consumes before reading/deleting KV in apps/api/src/services/bootstrap.ts; service and route tests cover one-winner concurrency, replay rejection, expired-token fail-closed behavior, encrypted callback token redemption, and bounded legacy plaintext compatibility.
• ProjectData messages: getMessages now parses rows individually and skips malformed rows with degraded logging in apps/api/src/durable-objects/project-data/messages.ts; project-data-messages.test.ts covers malformed-row isolation.
• Deploy workflow config: deploy-reusable.yml now forwards an identical, explicitly-duplicated Wrangler sync env to both sync steps (YAML anchors were removed in 102125f because GitHub Actions does not support them) and fails closed on workers.dev setup failure; deploy-reusable-workflow.test.ts, sync-wrangler-config.test.ts, and check-wrangler-bindings.ts validate env parity, max_instances config, workers.dev fail-closed behavior, and Worker secret inventory docs.
• VM-agent shutdown: Server.Stop and SessionManager.Stop are idempotent via sync.Once and wait for cleanup; Go tests cover repeated and concurrent stops plus cleanup goroutine exit.

Untested Gaps

None outstanding. Staging verification is complete: deploy green, Playwright validation of the affected
surfaces passed with zero errors, and a real VM was booted, exercised, and torn down (rule 6b).

Post-Mortem (Required for bug fix PRs)

What broke

Eight strict-CTO remediations addressed separate reliability/configuration/security defects that were completed independently and needed safe combined integration.

Root cause

Multiple independent remediation branches touched overlapping deployment/test/bootstrap/runtime surfaces; this PR combines them to avoid serially merging partially validated fixes.

Class of bug

Integration-risk remediation bundle: branch safety, deployment config drift, fail-open deployment prerequisite, secret inventory drift, shutdown idempotency, configurable infra capacity, malformed persisted data isolation, and token redemption race.

Why it wasn't caught

Each fix was developed independently. The remaining risk was cross-PR interaction, especially deploy workflow tests and shared env mappings.

Process fix included in this PR

• .claude/rules/07-env-and-urls.md updated for Wrangler sync env parity.
• Source remediation task archives preserved under tasks/archive/.

Post-mortem file

• tasks/active/2026-07-29-strict-cto-remediation-mega-pr.md
• Component archives under tasks/archive/2026-07-29-*.md

Specialist Review Evidence (Required for agent-authored PRs)

• All local reviewers completed and findings addressed before merge
• If any reviewer did NOT complete: needs-human-review label added and merge deferred to human — N/A: spawned local subagents were blocked by sandbox access, so equivalent specialist review was completed directly in the main session with the same skill instructions; no subagent code findings existed to address.

Reviewer	Status	Outcome
task-completion-validator	PASS	Main-session review against task file and origin/main...HEAD: planned integration/local-validation/review items are represented in diff and tests; remaining PR/CI/staging/merge checklist items intentionally pending.
cloudflare-specialist	PASS	Re-run 2026-08-06 as a real local subagent against the merge with origin/main. Adversarially reviewed all three conflict resolutions. Verdict: all correct, no regression of #1649's migration-tag safety. Verified durableObjectMigrations is the resolved value (not a passthrough), enumerated all 8 of main's binding checks as still running after the refactor, and structurally deep-compared both sync env blocks (45/45 keys+values identical). Also found the exact-copy resolution repairs pre-existing env drift on BOTH parents. One non-blocking coverage gap filed: tasks/backlog/2026-08-06-wrangler-sync-env-parity-test-coverage-gap.md.
env-validator	PASS	Reviewed GH/GITHUB mapping and shared Wrangler sync env. No merge-blocking findings; quality:wrangler-bindings passed with 34 configured secrets documented.
go-specialist	PASS	Reviewed VM-agent shutdown/session idempotency changes and tests. go test ./... passed. No merge-blocking findings.
security-auditor	PASS	Reviewed bootstrap token D1 consume ledger, token hashing, replay/expiry fail-closed behavior, and legacy bounds. No merge-blocking findings.
doc-sync-validator	PASS	Reviewed self-hosting/security docs and Worker secret inventory updates. No merge-blocking findings.
constitution-validator	PASS	Reviewed configurable TTLs/limits and no-hardcoded-values risks; max_instances and bootstrap TTL have config/default patterns. No merge-blocking findings.
test-engineer	PASS	Reviewed targeted tests and full suite results, including vertical-slice-style D1-backed bootstrap route/service tests and Go concurrency tests. No merge-blocking findings.

Review provenance (important — this table was partly rebuilt for accuracy):

• The 2026-08-05 rows were produced by main-session review, not by spawned subagents: four spawned
  read-only local subagents had failed with a sandbox error (bwrap: loopback: Failed RTM_NEWADDR)
  and reported no implementation findings. Those rows reflect the same specialist instruction files
  applied directly, against the pre-merge tree.
• The cloudflare-specialist row was re-run on 2026-08-06 as a genuine local subagent against the
  new merge with origin/main, because the merge introduced a new risk surface (three conflicts in
  exactly the deploy/Durable-Object-migration code that fix: preserve Durable Object migration compatibility #1649 changed) that the 2026-08-05 review could
  not have covered. It is the reviewer that matched the changed surface; the Go, security, and docs
  surfaces were untouched by the merge (packages/vm-agent/internal/server/server.go auto-merged with
  additive, orthogonal changes only: a JWT fetch timeout and two ACP report timeouts).

Exceptions (If any)

• Scope: local subagent execution environment
• Rationale: subagents were blocked by sandbox access to sibling worktree; main-session specialist review completed instead using the required skill instructions and concrete file/diff inspection.
• Expiration: this PR only; staging/CI/merge gates remain mandatory.

Agent Preflight (Required)

• Preflight completed before code changes

Classification

• external-api-change
• cross-component-change
• business-logic-change
• public-surface-change
• docs-sync-change

• infra-change

External References

N/A: integration of existing repo PRs; no new external API behavior beyond existing Cloudflare/GitHub/Worker deployment surfaces.

Codebase Impact Analysis

Affected components: apps/api bootstrap/task-runner/ProjectData/Worker config, .github/workflows/deploy-reusable.yml, scripts/deploy, scripts/quality, packages/vm-agent, public docs in apps/www, and task records.

Documentation & Specs

Updated/preserved docs: apps/www/src/content/docs/docs/architecture/security.md, apps/www/src/content/docs/docs/guides/self-hosting.mdx, .claude/rules/07-env-and-urls.md, task archives.

Constitution & Risk Check

Checked no-breaking-change requirements, fail-closed security behavior, no hardcoded values, env parity, D1 migration safety/order, and staging gate requirements. Remaining risk is live staging behavior; this PR is not merge-ready until staging validation and CI are green.

Staging validation update for PR #1697 — blocked before merge

Confirmed green evidence for the current PR head:

• PR Integrate strict CTO remediation fixes #1697 is open/mergeable on sam/execute-task-using-skill-ggdn3n at f5795ea09fee0f02c425ba9545f5a83de0760868.
• CI check rollup is green for that head.
• Deploy Staging run 30489511963 completed successfully for the same head.
  • deploy / Validate Configuration: success
  • deploy / Deploy to Cloudflare: success
  • deploy steps included Pulumi up, Wrangler config sync, workers.dev setup, migrations, API deploy, web deploy, VM-agent binary build/upload, CLI binary build/upload, health check
  • smoke-tests: success

Supplemental runtime evidence gathered from SAM MCP dispatch (not counted as the required staging Playwright evidence because returned URLs are production-domain):

• Claude task 01KYQWGNDNN514XBVMGAETECA2: completed, output branch sam/staging-validation-task-pr-eteca2, returned valid ProjectData message-listing answer citing malformed-row isolation/skipping behavior.
• Codex task 01KYQWH68T0XD011BWGNWEJ93M: in progress at last poll, output branch sam/staging-validation-task-pr-wej93m.

Merge blocker:

The required live staging validation via Playwright token-login could not complete. POST https://api.sammy.party/api/auth/token-login returned 429 RATE_LIMIT_EXCEEDED for the smoke-token login path after retries and waits, including switching from the primary to secondary smoke token variable. Because the required browser-authenticated staging validation and Claude+Codex staging core workflow checks have not passed, I did not merge this PR.

Temporary local validation setup performed: installed repo dependencies, Playwright Chromium, and Chromium OS deps in the validation workspace. No PR code changes were pushed.

[simple-agent-manager]

Staging validation blocker for PR #1697 (head f5795ea). Do not merge yet.

Evidence collected 2026-07-29 UTC:

• PR Integrate strict CTO remediation fixes #1697 is open, non-draft, mergeStateStatus=CLEAN at head f5795ea; PR checks are green.
• Deploy Staging run 30489511963 is success for the same head SHA. Successful jobs included deploy / Validate Configuration, deploy / Deploy to Cloudflare, and smoke-tests. Deploy steps included migrations, post-migration integrity check, API Worker deploy, Web UI deploy, VM Agent build/upload, CLI build/upload, and Health Check.
• Playwright browser auth through POST https://api.sammy.party/api/auth/token-login using SAM_PLAYWRIGHT_PRIMARY_USER returned 200; browser loaded https://app.sammy.party/dashboard with title 'Simple Agent Manager'.
• Authenticated staging API surface checks returned project/session/task data for project 01KJNR9R3TEN3KX1ETE33852R8 (Test Project 1, serverspresentation2025/crewai): projects count=15, sessions list count=10, tasks list count=10.
• ProjectData message listing worked for the validation sessions: Claude session message listing returned 35 messages; Codex session message listing returned 4 messages.
• Claude core workflow validation passed: task 01KYQYAS8Z54NTM92206E88JWE, session 6b6e9217-ffcd-4c94-a97a-5c6d70fd6cc5, output branch sam/validation-request-pr1697-staging-e88jwe. Claude produced a relevant response about codebase evidence from README/package/test-suite signals.

Blocking gate failure:

• Mandatory Codex core workflow validation did not produce a valid agent response.
• First Codex attempt: task 01KYQYJQM3V48XXK2AKD1R4VW2, session 7d10433d-bf9d-45ff-a4c1-8ebe5418ff63, output branch sam/validation-request-pr1697-staging-1r4vw2. Assistant response: 'Your access token could not be refreshed because your refresh token was already used. Please log out and sign in again.'
• Retry through explicit primary-user Codex profile 'Codex MCP Test' (profile 01KYQ5YDHC1VS0BZ9F3NY97FNH): task 01KYQYPN9XY3A64B3AX5MCDZQT, session f31bf01e-a9e4-4400-a4c3-740dc4dd3c14, output branch sam/validation-request-pr1697-codex-mcdzqt. Same assistant response: 'Your access token could not be refreshed because your refresh token was already used. Please log out and sign in again.'

Because the task explicitly requires a good/valid staging response against BOTH Claude and Codex before merge, I did not merge PR #1697.

[simple-agent-manager]

Staging verification blocker (2026-08-05 UTC)

• Rebased integration head: bf33e5172; all component heads Fix task workspace output branch checkout #1689-Fix atomic bootstrap token redemption #1696 accounted for.
• Local full gates and all mandatory specialist reviews passed; PR CI is green except checks still settling where applicable.
• Deleted all nodes visible to the staging smoke user before deployment and verified GET /api/nodes returned 0.
• Deploy Staging run 31055393932 passed, including D1 migrations/data-integrity checks, API/UI deploy, vm-agent binary upload, health check, and workflow smoke tests.
• Live Playwright regression evidence passed: token login 200, API health 200, dashboard/project/settings each 200, and zero browser console errors.
• ProjectData live message listing passed on both real dispatch attempts (user + system rows returned without list failure).
• Fresh Claude task dispatch attempts 01KZA42B1SGMEYS64RC1KM55QB and 01KZA4C52AC3X1D3FQM9E4VYQ0 both failed during node_provisioning before a workspace was created with exact error: hetzner API error (403): server limit reached.
• Read-only global staging D1 inspection shows no active nodes beyond the failed record; the only enabled platform cloud-provider credential is Hetzner. A bounded retry after cleanup failed identically.

This is not one of the authorized pre-existing exceptions (token-login 429 or Codex refresh-token reuse). It blocks the required fresh bootstrap/workspace creation and output-branch checkout evidence, so PR #1697 has not been merged. Human action is needed to free/increase the Hetzner project server quota or remove orphan servers directly in Hetzner, then rerun staging verification.
