feat(plugins): atomic install — stage→snapshot→swap→marker (docker path)

Closes molecule-core#114 for the docker (local-OSS) path.
EIC (SaaS) path tracked as a follow-up — same shape, different
exec primitives (ssh vs docker exec); shipping both in one PR
doubles the test surface.

THE FOUR-STEP DANCE
  1. STAGE     — docker.CopyToContainer extracts tar into
                 /configs/plugins/.staging/<name>.<ts>/
  2. SNAPSHOT  — if /configs/plugins/<name>/ exists, mv to
                 /configs/plugins/.previous/<name>.<ts>/
  3. SWAP      — atomic mv staging → live (single rename(2))
  4. MARKER    — touch /configs/plugins/<name>/.complete

Workspace-side plugin loaders should refuse to load any plugin dir
without .complete (separate small change, not in this PR — the marker
write is the necessary precursor; consumer side is a follow-up so
existing-content plugins don't break before they're re-installed).

ROLLBACK
  - Stage failure: rm -rf staging dir; live untouched
  - Snapshot failure: rm -rf staging dir; live untouched (no rename happened)
  - Swap failure with snapshot present: mv previous back to live
  - Swap failure (no snapshot): rm -rf staging; live (which never
    existed) stays absent
  - Marker failure: content already in place, log loudly with manual
    recovery hint (touch <plugin>/.complete) — don't roll back since
    the new content is what we wanted, just unmarked

GC
  Best-effort delete of previous-version snapshot after successful
  marker write. Failures non-fatal — next install or a separate
  sweeper reclaims. Sweeper for stale .previous/* across reboots is
  follow-up scope.

CONCURRENCY
  Each install gets a unique stamp (UTC second precision), so two
  concurrent reinstalls land in distinct staging dirs and the second
  swap simply overwrites the first's live result. The atomicity is
  per-install, not cross-install — by design (the platform serializes
  POST /workspaces/:id/plugins via Go-side semaphore upstream of
  this code, so cross-install collisions don't reach here).

CHANGES
  + plugins_atomic.go        — installVersion + atomicCopyToContainer
  + plugins_atomic_tar.go    — tarWalk/tarHostDirWithPrefix helpers
  + plugins_atomic_test.go   — 5 unit tests (paths, stamp shape,
                               tar happy path, symlink-skip, prefix
                               normalization). All green.
  ~ plugins_install_pipeline.go::deliverToContainer — swap
    copyPluginToContainer call to atomicCopyToContainer

Old copyPluginToContainer is retained (still called by Download()) so
this PR is purely additive on the install path; no public API change.

PHASE 4 SELF-REVIEW (FIVE-AXIS)
  Correctness: Required (addressed) — swap-failure rollback writes mv
    of previous back to live before returning the error; if rollback
    itself fails, we wrap both errors and surface the combined fault.
    Marker-write failure is treated as content-landed-but-unmarked
    (LOG, don't roll back the new content).
  Readability: No finding — installVersion path methods make the
    /staging/.previous/live/marker layout obvious from one struct.
    tarWalk extracted from the inline filepath.Walk in
    plugins_install_pipeline.go for testability.
  Architecture: No finding — atomicCopyToContainer composes existing
    execAsRoot / docker.CopyToContainer primitives; no new dependencies.
    Old copyPluginToContainer kept for Download() — single responsibility
    per function.
  Security: No finding — symlinks still skipped during tar walk
    (defense vs hostile plugin escaping its own dir). Marker writes
    use composeable path.Join, no user input touches the path.
  Performance: No finding — adds ~3 docker exec calls per install
    (mkdir, mv-snapshot, mv-swap, touch — actually 4) on top of the
    one CopyToContainer. Each exec ~50-100ms in practice; install
    end-to-end was already seconds-scale, this rounds to noise.

+# ============================================================
+# What this workflow does
+# ============================================================
 #
-# Safety model:
-# - Runs ONLY on workflow_run events for the staging branch.
-# - Requires EVERY named gate workflow to have the same head_sha and
-#   all be `conclusion == success`. If any of them is red, skipped,
-#   cancelled, or pending, we abort (stay on the current main).
-# - The PR base=main head=staging path lets GitHub itself enforce
-#   branch protection. If main has diverged from staging or required
-#   checks aren't satisfied, the merge queue declines the PR — no
-#   need for a manual ff-only ancestry check here.
-# - Loop safety: the auto-sync-main-to-staging workflow fires when
-#   main lands the auto-promote PR, but its merge into staging is by
-#   GITHUB_TOKEN which doesn't trigger downstream workflow_run events
-#   (GitHub Actions safety). So this workflow doesn't re-fire from
-#   its own promote landing.
+# 1. On a workflow_run completion event for one of the staging gate
+#    workflows (CI, E2E Staging Canvas, E2E API Smoke, CodeQL),
+#    checks if the combined status on the staging head SHA is green.
+# 2. If green, opens (or re-uses) a PR `head: staging → base: main`
+#    via Gitea REST `POST /api/v1/repos/.../pulls`.
+# 3. Schedules auto-merge via `POST /api/v1/repos/.../pulls/{index}/merge`
+#    with `merge_when_checks_succeed: true`. Gitea waits for the
+#    approval requirement on `main` (`required_approvals: 1`) and
+#    the status-check gates, then merges.
+# 4. The merge commit lands on `main` and fires
+#    `publish-workspace-server-image.yml` naturally via its
+#    `on: push: branches: [main]` trigger — no explicit dispatch
+#    needed (see "Why no workflow_dispatch tail" below).
 #
-# Toggle via repo variable AUTO_PROMOTE_ENABLED (true/unset). When
-# unset, the workflow logs what it would have done but doesn't open
-# the PR — useful for dry-running the gate logic without surfacing
-# a noisy PR while staging CI is still flaky.
+# `auto-sync-main-to-staging.yml` is the reverse-direction
+# counterpart (main → staging, fast-forward push). Together they
+# keep the staging-superset-of-main invariant tight.
 #
-# **One-time repo setting (load-bearing):** this workflow opens the
-# staging→main PR via `gh pr create` using the default GITHUB_TOKEN.
-# Since GitHub's 2022 default change, that token cannot create or
-# approve PRs unless the repo opts in. The toggle is at:

+# Why Gitea REST (and not `gh pr create`)
+# ============================================================
 #
-#   Settings → Actions → General → Workflow permissions
-#   → ✅ Allow GitHub Actions to create and approve pull requests
+# Pre-2026-05-06 this workflow used `gh pr create`, `gh pr merge --auto`,
+# `gh run list`, and `gh workflow run` against GitHub. After the
+# GitHub→Gitea cutover those calls fail because:
 #
-# Without it, every workflow_run fails with:
+#   - `gh pr create / merge / view / list` route to GitHub GraphQL
+#     (`/api/graphql`). Gitea does not expose a GraphQL endpoint;
+#     every call returns `HTTP 405 Method Not Allowed` — same root
+#     cause as #65 (auto-sync) which PR #66 fixed by dropping `gh`
+#     entirely.
+#   - `gh run list --workflow=...` GitHub-shape; Gitea has the
+#     simpler `GET /repos/.../commits/{ref}/status` combined-status
+#     endpoint instead.
+#   - `gh workflow run X.yml` calls `POST /repos/.../actions/workflows/{id}/dispatches`,
+#     which does NOT exist on Gitea 1.22.6 (verified via swagger.v1.json).
 #
-#   pull request create failed: GraphQL: GitHub Actions is not
-#   permitted to create or approve pull requests (createPullRequest)

-# errors after a repo or org admin change.
+# ============================================================
+# Why no workflow_dispatch tail (was load-bearing on GitHub, dead on Gitea)
+# ============================================================
+#
+# The GitHub-era version had a 60-line polling step that waited for
+# the promote PR to merge, then explicitly dispatched
+# `publish-workspace-server-image.yml` on `--ref main`. That step
+# existed because GitHub's GITHUB_TOKEN-initiated merges suppress
+# downstream `on: push` workflows (the documented "no recursion" rule
+# — https://docs.github.com/en/actions/using-workflows/triggering-a-workflow#triggering-a-workflow-from-a-workflow).
+# The explicit dispatch was the workaround.
+#
+# Gitea Actions does NOT have this no-recursion rule. PR #66's auto-
+# sync merge to main fired `auto-promote-staging` on the next push
+# trigger naturally. So the cascade fires on the natural push event;
+# the explicit dispatch is dead code. (And even if we wanted to
+# preserve it, Gitea has no `workflow_dispatch` REST endpoint.)
+#
+# Removed in this rewrite. If we ever observe the cascade misfire,
+# operator can push an empty commit to `main` to wake it.
+#
+# ============================================================
+# Why open a PR (and not direct push)
+# ============================================================
+#
+# `main` branch protection has `enable_push: false` with NO
+# `push_whitelist_usernames`. Direct push is impossible for any
+# persona, including admins. PR-mediated merge is the only path,
+# which is intentional: prod state mutations (and staging→main IS a
+# prod mutation, since the next deploy fans out to tenants) require
+# Hongming's approval per `feedback_prod_apply_needs_hongming_chat_go`.
+#
+# The auto-merge schedule preserves this gate: `merge_when_checks_succeed`
+# does NOT bypass `required_approvals: 1`. Gitea waits for BOTH
+# approval AND green checks before merging. Hongming reviews via the
+# canvas/chat-handle of the PR notification, approves, and Gitea
+# auto-merges within seconds.
+#
+# ============================================================
+# Identity + token (anti-bot-ring per saved-memory
+# `feedback_per_agent_gitea_identity_default`)
+# ============================================================
+#
+# This workflow uses `secrets.AUTO_SYNC_TOKEN` — a personal access
+# token issued to the `devops-engineer` Gitea persona. NOT the
+# founder PAT. The bot-ring fingerprint that triggered the GitHub
+# org suspension on 2026-05-06 was characterised by founder PAT
+# acting as CI at machine speed.
+#
+# Token scope: `push: true` (read+write) on this repo. The persona
+# can: open PRs, comment on PRs, schedule auto-merge. The persona
+# CANNOT bypass main's branch protection (`required_approvals: 1`
+# still applies — only Hongming's review unblocks merge).
+#
+# Authorship: the PR is opened by `devops-engineer`; the merge
+# commit credits Hongming-as-approver and `devops-engineer` as
+# the merger.
+#
+# ============================================================
+# Failure modes & operational notes
+# ============================================================
+#
+# A — staging gates not all green at trigger time:
+#     - The combined-status check returns `state: pending|failure`.
+#       Workflow exits 0 with a step-summary "not all green; staying
+#       on current main". Re-fires on the next gate completion.
+#
+# B — Gitea PR-create returns non-201 (e.g. 422 already-exists):
+#     - Idempotent: the workflow first GETs the existing open
+#       staging→main PR. If found, reuse it; if not, POST a new one.
+#       422 should never surface; if it does (race), step summary
+#       captures the body and the next workflow_run picks up.
+#
+# C — `merge_when_checks_succeed` schedule fails:
+#     - 422 with "Pull request is not mergeable" if there are
+#       conflicts or stale base. Step summary surfaces it; operator
+#       (or `auto-sync-main-to-staging`) needs to bring staging up
+#       to date with main first. Workflow exits 1 to surface red.
+#
+# D — `AUTO_SYNC_TOKEN` rotated / wrong scope:
+#     - 401/403 on first REST call. Step summary surfaces it.
+#       Re-issue the token from `~/.molecule-ai/personas/` on the
+#       operator host and update the repo Actions secret.
+#
+# ============================================================
+# Loop safety
+# ============================================================
+#
+# When the promote PR merges to main, `auto-sync-main-to-staging.yml`
+# fires (on:push:main) and pushes the merge commit back to staging.
+# That push to staging is by `devops-engineer`, NOT this workflow's
+# token, and triggers the staging gate workflows. When they all
+# complete, we end up back here — but the tree-diff guard catches
+# it: staging tree == main tree (the merge commit changes nothing),
+# so we skip and the cycle terminates.

+name: Auto-sync canary — AUTO_SYNC_TOKEN rotation drift
+
+# Synthetic health check for the AUTO_SYNC_TOKEN secret consumed by
+# auto-sync-main-to-staging.yml (PR #66) and publish-workspace-server-image.yml.
+#
+# ============================================================
+# Why this workflow exists
+# ============================================================
+#
+# PR #66 fixed auto-sync (replaced GitHub-era `gh pr create` — which
+# 405s on Gitea's GraphQL endpoint — with a direct git push from the
+# `devops-engineer` persona's `AUTO_SYNC_TOKEN`). Hostile self-review
+# weakest spot #3 of that PR:
+#
+#   "Token rotation silently breaks auto-sync. If AUTO_SYNC_TOKEN is
+#    rotated without updating the repo secret, every push to main
+#    fails red on the auto-sync push step. The workflow surfaces the
+#    failure mode in the step summary (failure mode B in the header),
+#    but there's no proactive monitoring."
+#
+# Detection latency under the status quo: rotation is only caught on
+# the next push to `main`. During quiet periods (no main push for
+# many hours) the staging-superset-of-main invariant silently breaks.
+#
+# This workflow closes the gap: every 6 hours, it fires the auth
+# surface that auto-sync depends on and emits a red workflow status
+# if AUTO_SYNC_TOKEN has drifted out of validity.
+#
+# ============================================================
+# What this checks (Option B — read-only verify)
+# ============================================================
+#
+# 1. `GET /api/v1/user` against Gitea with the token → validates the
+#    token authenticates AND resolves to `devops-engineer` (catches
+#    the case where the token was regenerated under a different
+#    persona by mistake).
+# 2. `GET /api/v1/repos/molecule-ai/molecule-core` with the token →
+#    validates the token has `read:repository` scope on this repo
+#    (the v2 scope contract — see saved memory
+#    `reference_persona_token_v2_scope`).
+# 3. `git push --dry-run` of the current staging SHA back to
+#    `refs/heads/staging` via `https://oauth2:<token>@<gitea>/...`
+#    → validates the EXACT HTTPS basic-auth path that
+#    `actions/checkout` + `git push origin staging` use inside
+#    auto-sync-main-to-staging.yml. NOP by construction (push the
+#    current tip to itself = "Everything up-to-date"); auth is
+#    checked at the smart-protocol handshake BEFORE the empty-diff
+#    computation, so bad token → exit 128 with "Authentication
+#    failed". `git ls-remote` is NOT used here because Gitea
+#    falls back to anonymous read on public repos and would
+#    silently green-light a rotated token.
+#
+# Each step exits non-zero with an actionable error message if it
+# fails. The workflow status itself is the operator-facing surface.
+#
+# ============================================================
+# What this does NOT check (intentional)
+# ============================================================
+#
+# - **Branch-protection authz** (failure mode C in auto-sync header):
+#   would require an actual write to staging. Already monitored by
+#   `branch-protection-drift.yml` daily. Don't duplicate.
+# - **Conflict resolution** (failure mode A): a real conflict is data-
+#   driven, not auth-driven; can't synthesise it without polluting
+#   staging. Already surfaces immediately on the next main push.
+# - **Concurrency** (failure mode D): handled by workflow concurrency
+#   group on auto-sync, not a credential issue.
+#
+# ============================================================
+# Why Option B (read-only) and not the alternatives
+# ============================================================
+#
+# Considered + rejected (see issue #72 for full write-up):
+#
+# - **Option A — full auto-sync on schedule**: every run creates a
+#   no-op merge commit on staging when main hasn't advanced. 4 noise
+#   commits/day. And races the real `push:` trigger when main has
+#   advanced. Rejected.
+#
+# - **Option C — push to dedicated `auto-sync-canary` branch**: would
+#   exercise authz too, but adds branch noise on Gitea AND requires
+#   maintaining a second branch protection (or expanding staging's
+#   whitelist to a junk branch). Authz already covered by
+#   `branch-protection-drift.yml`. Rejected.
+#
+# Prior art for the chosen Option B shape:
+#   - Cloudflare's `/user/tokens/verify` endpoint (read-only auth
+#     probe explicitly designed for credential canaries).
+#   - AWS Secrets Manager rotation Lambda's `testSecret` step (auth
+#     probe before promoting AWSPENDING → AWSCURRENT).
+#   - HashiCorp Vault's `vault token lookup` for renewal canaries.
+#
+# ============================================================
+# Operator runbook — what to do when this workflow goes RED
+# ============================================================
+#
+# 1. **Identify which step failed**:
+#    - Step "Verify token authenticates as devops-engineer" red →
+#      token is invalid OR resolves to wrong persona.
+#    - Step "Verify token has repo read scope" red → token valid but
+#      stripped of `read:repository` scope (or repo perms changed).
+#    - Step "Verify git HTTPS auth path via no-op dry-run push to
+#      staging" red → token rotated/revoked OR Gitea git-HTTPS
+#      surface is broken (rare). Auth check happens on the
+#      smart-protocol handshake, separate from the API path.
+#
+# 2. **Re-issue the token** on the operator host:
+#    ```
+#    ssh root@5.78.80.188 'docker exec --user git molecule-gitea-1 \
+#      gitea admin user generate-access-token \
+#      --username devops-engineer \
+#      --token-name persona-devops-engineer-vN \
+#      --scopes "read:repository,write:repository,read:user,read:organization,read:issue,write:issue,read:notification,read:misc"'
+#    ```
+#    Update `/etc/molecule-bootstrap/agent-secrets.env` in place
+#    (per `feedback_unified_credentials_file`). The previous token
+#    file lands at `.bak.<date>`.
+#
+# 3. **Update the repo Actions secret** at:
+#    Settings → Secrets and variables → Actions → AUTO_SYNC_TOKEN
+#    Paste the new token. (Don't echo it in chat — but per
+#    `feedback_passwords_in_chat_are_burned`, a paste in a 1:1
+#    Claude session is within trust boundary.)
+#
+# 4. **Re-run this canary** via workflow_dispatch. Confirm GREEN.
+#
+# 5. **Backfill any missed main → staging syncs** by re-running
+#    `auto-sync-main-to-staging.yml` from its workflow_dispatch
+#    surface, OR by pushing an empty commit to main (if you'd
+#    rather force a real trigger).
+#
+# ============================================================
+# Security notes
+# ============================================================
+#
+# - Token usage: read-only (`GET /api/v1/user`, `GET /api/v1/repos/...`,
+#   `git ls-remote`). No write paths. Same blast-radius profile as
+#   `actions/checkout` on a public repo.
+# - The token NEVER appears in logs: every `curl` uses a header
+#   variable, never inline; the `git ls-remote` URL builds the
+#   `oauth2:$TOKEN@host` form into a single env var that's not
+#   echoed. GitHub Actions secret-masking covers anything that does
+#   slip through.
+# - No new token introduced — same `AUTO_SYNC_TOKEN` the workflow
+#   under monitor uses. Per least-privilege we deliberately do NOT
+#   broaden scope for the canary.

 # Reflects every push to `main` back onto `staging` so the
 # staging-as-superset-of-main invariant holds.
 #
-# Background:
+# ============================================================
+# What this workflow does
+# ============================================================
 #
-# `auto-promote-staging.yml` advances main via `git merge --ff-only`
-# + `git push origin main` — that's a clean fast-forward, no merge
-# commit. But manual merges of `staging → main` PRs through the
-# GitHub UI / API create a merge commit on main that staging
-# doesn't have. The next `staging → main` PR then evaluates as
-# "BEHIND" because staging is missing that merge commit, requiring
-# a manual `gh pr update-branch` round-trip.
+# On every push to `main`:
+#   1. Checks if staging already contains main → no-op.
+#   2. Fetches both branches, merges main into staging in the
+#      runner workspace (fast-forward if possible, else
+#      `--no-ff` merge commit).
+#   3. Pushes staging directly to origin via the
+#      `devops-engineer` persona's `AUTO_SYNC_TOKEN`.
 #
-# This happened twice on 2026-04-28 (PRs #2202, #2205, both manual
-# bridges). Each time the bridge needed update-branch + a re-CI
-# round before merging. Operationally annoying and avoidable.
+# Authoritative path: a single `git push origin staging` from
+# inside this workflow is the SSOT for advancing staging after
+# a main push. No PR, no merge queue, no human approval —
+# staging is mechanically maintained as a superset of main.
 #
-# Architecture:
+# `auto-promote-staging.yml` is the reverse-direction
+# counterpart (staging → main, gated on green CI). Together
+# they keep the staging-superset-of-main invariant tight.
 #
-# This repo's `staging` branch is protected by a `merge_queue`
-# ruleset (id 15500102) that blocks ALL direct pushes — no bypass
-# even for org admins or the GitHub Actions integration. Direct
-# `git push origin staging` returns GH013. So instead of pushing
-# directly, this workflow:
+# ============================================================
+# Why direct push (and not "open a PR")
+# ============================================================
 #
-#   1. Checks if main is already in staging's ancestry → no-op.
-#   2. Creates an `auto-sync/main-<sha>` branch from staging.
-#   3. Tries `git merge --ff-only origin/main` → if staging hasn't
-#      diverged this is a clean ff.
-#   4. Otherwise `git merge --no-ff origin/main` to absorb main's
-#      tip while keeping staging's history.
-#   5. Pushes the auto-sync branch.
-#   6. Opens a PR (base=staging, head=auto-sync/main-<sha>) and
-#      enables auto-merge so the merge queue lands it.
+# Pre-2026-05-06 the canonical SCM was GitHub.com, where:
+#   - The `staging` branch had a `merge_queue` ruleset that
+#     blocked ALL direct pushes (no bypass even for org
+#     admins or the GitHub Actions integration).
+#   - Therefore this workflow opened a PR via `gh pr create`
+#     and let auto-merge land it through the queue.
 #
-# This mirrors the path human PRs take through staging — same
-# rules, same gates, no special-case bypass.
+# Post-2026-05-06 the canonical SCM is Gitea
+# (`git.moleculesai.app/molecule-ai/molecule-core`). Gitea:
+#   - Has no `merge_queue` concept.
+#   - Allows direct push to protected branches via per-user
+#     `push_whitelist_usernames` on the branch protection.
+#   - Does not expose a GraphQL endpoint, so `gh pr create`
+#     returns `HTTP 405 Method Not Allowed
+#     (https://git.moleculesai.app/api/graphql)` — the
+#     pre-suspension architecture cannot work on Gitea.
 #
-# Loop safety:
+# The molecule-ai/molecule-core staging branch protection
+# (verified via `GET /api/v1/repos/.../branch_protections`)
+# whitelists `devops-engineer` for direct push. So the
+# correct Gitea-shape architecture is: authenticate as
+# `devops-engineer`, merge locally, push staging directly.
 #
-# `GITHUB_TOKEN`-authored merges (including the merge queue's land
-# of the auto-sync PR) do NOT trigger downstream workflow runs
-# (GitHub Actions safety). So when the auto-sync PR lands on
-# staging, `auto-promote-staging.yml` is NOT triggered by that
-# push. The next developer push to staging triggers auto-promote
-# normally. No loop possible.
+# This is structurally simpler than the GitHub-era PR dance
+# and removes the dependence on `gh` CLI / GraphQL entirely.
 #
-# Concurrency:
+# ============================================================
+# Identity + token (anti-bot-ring per saved-memory
+# `feedback_per_agent_gitea_identity_default`)
+# ============================================================
 #
-# Two pushes to main in quick succession (e.g., manual UI merge
-# immediately followed by auto-promote-staging's ff-merge) could
-# otherwise open two overlapping auto-sync PRs. The concurrency
-# group serializes runs; the second waits for the first to exit.
-# (The first run exits after opening + auto-merge-queueing the PR,
-# not after the merge actually completes — so multiple PRs can be
-# open simultaneously, but the merge queue handles them serially.)
+# This workflow uses `secrets.AUTO_SYNC_TOKEN`, which is a
+# personal access token issued to the `devops-engineer`
+# persona on Gitea — NOT the founder PAT. The bot-ring
+# fingerprint that triggered the GitHub org suspension on
+# 2026-05-06 was characterised by founder PAT acting as CI
+# at machine speed; per-persona identities split the
+# attribution honestly.
+#
+# Token scope on Gitea: repo write. Push target restricted
+# to `staging` (this workflow is the only writer; main is
+# untouched). Compromise blast radius: bounded to staging
+# branch + this repo's read surface.
+#
+# Commits are authored by the persona email
+# `devops-engineer@agents.moleculesai.app` so commit history
+# reflects which automation produced the merge.
+#
+# ============================================================
+# Failure modes & operational notes
+# ============================================================
+#
+# A — staging has commits main doesn't, and the merge
+#     conflicts:
+#     - The `--no-ff` merge step exits non-zero. Workflow
+#       fails red. Operator (devops-engineer or human)
+#       resolves manually:
+#         git fetch origin
+#         git checkout staging
+#         git merge --no-ff origin/main
+#         # resolve conflicts
+#         git push origin staging
+#     - Step summary surfaces the conflict so the failed run
+#       is self-explanatory.
+#
+# B — `AUTO_SYNC_TOKEN` rotated / wrong scope:
+#     - `git push` step exits non-zero with `HTTP 401` /
+#       `403`. Step summary surfaces the failed push.
+#     - Re-issue the token from `~/.molecule-ai/personas/`
+#       on the operator host and update the repo Actions
+#       secret. Re-run the workflow.
+#
+# C — staging branch protection no longer whitelists
+#     `devops-engineer`:
+#     - `git push` exits non-zero with a Gitea protected-
+#       branch rejection. Step summary surfaces it.
+#     - Re-add `devops-engineer` to
+#       `push_whitelist_usernames` on the staging
+#       protection (Settings → Branches → staging).
+#
+# D — concurrent push to main while a sync is in flight:
+#     - The `concurrency` group below serialises runs.
+#       The second waits for the first; if main advances
+#       again while we're syncing, the second run picks
+#       up the new tip on its own fetch.
+#
+# ============================================================
+# Loop safety
+# ============================================================
+#
+# The push to staging from this workflow does NOT itself
+# fire a `push: branches: [main]` event (different branch),
+# so there's no risk of self-recursion. `auto-promote-staging.yml`
+# fires on `workflow_run` of CI etc. — it sees the new
+# staging tip on its next gate-completion event, NOT on this
+# push directly. No loop.

-# Controls CodeQL scan triggers for this repo.
+# Stub workflow — CodeQL Action is structurally incompatible with Gitea
+# Actions (post-2026-05-06 SCM migration off GitHub).
 #
-# GitHub's "Code quality" default setup (the UI-configured one) is
-# hardcoded to only scan the default branch — on this repo that's
-# `staging`, so PRs promoting staging→main would otherwise never be
-# scanned. This workflow fills that gap by explicitly scanning both
-# branches on push and PR.
+# Why this is a stub, not a real CodeQL run:
 #
-# Runs on ubuntu-latest (GHA-hosted — public repo, free). GHAS is NOT
-# enabled on this repo, so results are not uploaded to the Security
-# tab — the scan fails the PR check on findings, and the SARIF is
-# kept as a workflow artifact for triage.
+# 1. github/codeql-action/init@v4 hits api.github.com endpoints
+#    (CodeQL CLI bundle download + query-pack registry + telemetry)
+#    that Gitea 1.22.x does NOT proxy. The act_runner has
+#    GITHUB_SERVER_URL=https://git.moleculesai.app correctly set
+#    (per saved memory feedback_act_runner_github_server_url and
+#    /config.yaml on the operator host), but the Gitea API surface
+#    simply does not implement the codeql-action bundle endpoints.
+#    Observed in run 1d/3101 (2026-05-07): "::error::404 page not
+#    found" inside the Initialize CodeQL step, before any analysis.
+#
+# 2. PR #35 attempted to mark `continue-on-error: true` at the JOB
+#    level (correct YAML structure). Gitea 1.22.6 does NOT propagate
+#    job-level continue-on-error to the commit-status API — every
+#    matrix leg still posts `failure` to the status surface, which
+#    keeps OVERALL=failure on every push to main + staging and
+#    blocks visual auto-promote signals (#156).
+#
+# 3. Hongming policy decision (2026-05-07, task #156): CodeQL is
+#    ADVISORY, not blocking, on Gitea Actions. We do not block PR
+#    merge or staging→main promotion on CodeQL findings until we
+#    have a Gitea-compatible static-analysis pipeline.
+#
+# What this stub preserves:
+#
+# - Workflow name `CodeQL` (referenced by auto-promote-staging.yml
+#   line 67 as a workflow_run gate — must stay stable).
+# - Job name template `Analyze (${{ matrix.language }})` and the
+#   3-leg matrix (go, javascript-typescript, python). Branch
+#   protection / required-check parity (#144) keys on these
+#   exact context names.
+# - merge_group + push + pull_request + schedule triggers, so the
+#   merge-queue check name still resolves (per saved memory
+#   feedback_branch_protection_check_name_parity).
+#
+# Re-enabling real analysis (future work):
+#
+# - Option A: self-hosted Semgrep / OpenGrep via a custom action
+#   that doesn't hit api.github.com. Tracked behind #156 follow-up.
+# - Option B: Sonatype Nexus IQ or similar, called from a step
+#   that uses the Gitea-issued token only.
+# - Option C: re-host this workflow on a small GitHub mirror used
+#   ONLY for SAST (push-mirrored from Gitea). Acceptable trade-off
+#   if/when payment is restored on a non-suspended GitHub org —
+#   but per saved memory feedback_no_single_source_of_truth, we
+#   should design for multi-vendor backup, not GitHub-only SAST.
+#
+# Until one of those lands, this stub keeps commit-status green so
+# the auto-promote chain isn't permanently red on a tool we cannot
+# actually run.
+#
+# Security policy: ADVISORY. We accept the residual risk of un-scanned
+# pushes during this window. Compensating controls in place:
+#   - secret-scan.yml runs on every push (active, blocks on hits)
+#   - block-internal-paths.yml blocks forbidden file paths
+#   - lint-curl-status-capture.yml catches one specific class of bug
+#   - branch-protection-drift.yml + the merge_group required-checks
+#     parity keep the gate surface stable
+# These are not equivalent to CodeQL coverage. Status of the
+# replacement plan is tracked in #156.

+# Same substrate hazard as PR #98 (handlers-postgres-integration). Our
+# Gitea act_runner runs with `container.network: host` (operator host
+# `/opt/molecule/runners/config.yaml`), which means:
+#
+#   * Two concurrent runs both try to bind their `-p 15432:5432` /
+#     `-p 16379:6379` host ports — the second postgres/redis FATALs
+#     with `Address in use` and `docker run` returns exit 125 with
+#     `Conflict. The container name "/molecule-ci-postgres" is already
+#     in use by container ...`. Verified in run a7/2727 on 2026-05-07.
+#   * The fixed container names `molecule-ci-postgres` / `-redis` (the
+#     pre-fix shape) collide on name AS WELL AS port. The cleanup-with-
+#     `docker rm -f` at the start of the second job KILLS the first
+#     job's still-running postgres/redis.
+#
+# Fix shape (mirrors PR #98's bridge-net pattern, adapted because
+# platform-server is a Go binary on the host, not a containerised
+# step):
+#
+#   1. Unique container names per run:
+#         pg-e2e-api-${RUN_ID}-${RUN_ATTEMPT}
+#         redis-e2e-api-${RUN_ID}-${RUN_ATTEMPT}
+#      `${RUN_ID}-${RUN_ATTEMPT}` is unique even across reruns of the
+#      same run_id.
+#   2. Ephemeral host port per run (`-p 0:5432`), then read the actual
+#      bound port via `docker port` and export DATABASE_URL/REDIS_URL
+#      pointing at it. No fixed host-port → no port collision.
+#   3. `127.0.0.1` (NOT `localhost`) in URLs — IPv6 first-resolve was
+#      the original flake fixed in #92 and the script's still IPv6-
+#      enabled.
+#   4. `if: always()` cleanup so containers don't leak when test steps
+#      fail.
+#
+# Issue #94 items #2 + #3 (also fixed here):
+#   * Pre-pull `alpine:latest` so the platform-server's provisioner
+#     (`internal/handlers/container_files.go`) can stand up its
+#     ephemeral token-write helper without a daemon.io round-trip.
+#   * Create `molecule-monorepo-net` bridge network if missing so the
+#     provisioner's container.HostConfig {NetworkMode: ...} attach
+#     succeeds.
+# Item #1 (timeouts) — evidence on recent runs (77/3191, ae/4270, 0e/
+# 2318) shows Postgres ready in 3s, Redis in 1s, Platform in 1s when
+# they DO come up. Timeouts are not the bottleneck; not bumped.
+#
+# Item explicitly NOT fixed here: failing test `Status back online`
+# fails because the platform's langgraph workspace template image
+# (ghcr.io/molecule-ai/workspace-template-langgraph:latest) returns
+# 403 Forbidden post-2026-05-06 GitHub org suspension. That is a
+# template-registry resolution issue (ADR-002 / local-build mode) and

+# Why this workflow does NOT use `services: postgres:` (Class B fix)
+# ------------------------------------------------------------------
+# Our act_runner config has `container.network: host` (operator host
+# /opt/molecule/runners/config.yaml), which act_runner applies to BOTH
+# the job container AND every service container. With host-net, two
+# concurrent runs of this workflow both try to bind 0.0.0.0:5432 — the
+# second postgres FATALs with `could not create any TCP/IP sockets:
+# Address in use`, and Docker auto-removes it (act_runner sets
+# AutoRemove:true on service containers). By the time the migrations
+# step runs `psql`, the postgres container is gone, hence
+# `Connection refused` then `failed to remove container: No such
+# container` at cleanup time.
 #
-# Cost: ~30s job (postgres pull from GH cache + go build + 4 tests).
+# Per-job `container.network` override is silently ignored by
+# act_runner — `--network and --net in the options will be ignored.`
+# appears in the runner log. Documented constraint.
+#
+# So we sidestep `services:` entirely. The job container still uses
+# host-net (inherited from runner config; required for cache server
+# discovery on the bridge IP 172.18.0.17:42631). We launch a sibling
+# postgres on the existing `molecule-monorepo-net` bridge with a
+# UNIQUE name per run — `pg-handlers-${RUN_ID}-${RUN_ATTEMPT}` — and
+# read its bridge IP via `docker inspect`. A host-net job container
+# can reach a bridge-net container directly via the bridge IP (verified
+# manually on operator host 2026-05-08).
+#
+# Trade-offs vs. the original `services:` shape:
+#   + No host-port collision; N parallel runs share the bridge cleanly
+#   + `if: always()` cleanup runs even on test-step failure

+# PR-time guards. Today the only guard is "disable auto-merge when a
+# new commit is pushed after auto-merge was enabled" — added 2026-04-27
+# after PR #2174 auto-merged with only its first commit because the
+# second commit was pushed after the merge queue had locked the PR's
+# SHA.
 #
-# When more PR-time guards land in molecule-ci, add them here as
-# additional jobs that share the same pull_request:synchronize
-# trigger.
+# Why this is inlined (not delegated to molecule-ci's reusable
+# workflow): the reusable workflow uses `gh pr merge --disable-auto`,
+# which calls GitHub's GraphQL API. Gitea has no GraphQL endpoint and
+# returns HTTP 405 on /api/graphql, so the job failed on every Gitea
+# PR push since the 2026-05-06 migration. Gitea also has no `--auto`
+# merge primitive that this job could be acting on, so the right
+# behaviour on Gitea is "no-op + green status" — not a 405.
+#
+# Inlining (vs. an `if:` on the `uses:` line) keeps the job ALWAYS
+# running, which matters for branch protection: required-check names
+# need a job that emits SUCCESS terminal state, not SKIPPED. See
+# `feedback_branch_protection_check_name_parity` and `feedback_pr_merge_safety_guards`.

+# Mechanical enforcement of SHARED_RULES rule 8 ("Staging-first
+# workflow, no exceptions"). When a bot opens a PR against `main`,
+# retarget it to `staging` automatically and leave an explanatory
+# comment. Human / CEO-authored PRs (the staging→main promotion
+# PRs, etc.) are left alone — they're the authorised exception
+# to the rule.
 #
-# Why an Action instead of only a prompt rule: prompt rules depend on every
-# role's system-prompt.md staying in sync. Today 5 of 8 engineer roles
-# (core-be, core-fe, app-fe, app-qa, devops-engineer) don't have the
-# staging-first section — the bot keeps opening PRs to main. An Action
-# enforces the invariant regardless of prompt drift.
+# ============================================================
+# What this workflow does
+# ============================================================
+#
+# On `pull_request_target` opened/reopened against `main`:
+#   1. If the PR head is `staging`, skip (the auto-promote PRs
+#      MUST stay base=main).
+#   2. If the PR author is a bot, retarget the PR base to
+#      `staging` via Gitea REST `PATCH /pulls/{N}` body
+#      `{"base":"staging"}`.
+#   3. If the retarget returns 422 "pull request already exists
+#      for base branch 'staging'" (issue #1884 case: another PR
+#      on the same head already targets staging), close the
+#      now-redundant main-PR via Gitea REST instead of failing
+#      red.
+#   4. Post an explainer comment on the retargeted PR via
+#      Gitea REST `POST /issues/{N}/comments`.
+#
+# ============================================================
+# Why Gitea REST (and not `gh api / gh pr close / gh pr comment`)
+# ============================================================
+#
+# Pre-2026-05-06 this workflow used `gh api -X PATCH "repos/{owner}/{repo}/pulls/{N}" -f base=staging`
+# plus `gh pr close` and `gh pr comment`. After the GitHub→Gitea
+# cutover those calls fail because:
+#
+#   - `gh` CLI defaults to `api.github.com`. Even with `GH_HOST`
+#     pointing at Gitea, `gh pr close / comment` route through
+#     GraphQL (`/api/graphql`) which Gitea does not expose.
+#     Empirical: every `gh pr *` call returns
+#     `HTTP 405 Method Not Allowed (https://git.moleculesai.app/api/graphql)`
+#     — same root cause as #65 (auto-sync, fixed in PR #66) and
+#     #73/#195 (auto-promote, fixed in PR #78).
+#   - `gh api -X PATCH /pulls/{N}` happens to use a REST path
+#     that Gitea also has, but the `gh` host-resolution layer
+#     and pagination/retry logic don't always hit Gitea cleanly,
+#     and the cost of switching to direct `curl` is one extra
+#     line of code.
+#
+# So this workflow uses direct `curl` calls to Gitea REST. No
+# `gh` CLI dependency, no GraphQL, no flaky host-resolution.
+#
+# ============================================================
+# Identity + token (anti-bot-ring per saved-memory
+# `feedback_per_agent_gitea_identity_default`)
+# ============================================================
+#
+# Pre-fix this workflow used the per-job ephemeral
+# `secrets.GITHUB_TOKEN`. On Gitea Actions that token has
+# narrow scope and unpredictable cross-PR write capability.
+#
+# Post-fix: `secrets.AUTO_SYNC_TOKEN` (the `devops-engineer`
+# Gitea persona). Same persona used by `auto-sync-main-to-staging.yml`
+# (PR #66) and `auto-promote-staging.yml` (PR #78). Token scope:
+# `push: true` repo write, sufficient for PR-edit + close + comment.
+#
+# Why this token does NOT need branch-protection bypass:
+# patching a PR's base ref is a PR-level operation that does not
+# require push perms on either branch (the PR's own commits stay
+# put; only the metadata changes).
+#
+# ============================================================
+# Failure modes & operational notes
+# ============================================================
+#
+# A — PATCH base→staging returns 422 "pull request already exists"
+#     (issue #1884 case):
+#     - Detected by string-match on response body. Workflow
+#       falls through to closing the now-redundant main-PR
+#       (Gitea REST `PATCH /pulls/{N}` with `state: closed`)
+#       and posts an explanation comment. Step summary surfaces.
+#
+# B — `AUTO_SYNC_TOKEN` rotated / wrong scope:
+#     - First REST call returns 401/403. Step summary surfaces.
+#       Re-issue token from `~/.molecule-ai/personas/` on the
+#       operator host and update repo Actions secret.
+#
+# C — PR was deleted between trigger and run:
+#     - REST call returns 404. Workflow exits 0 with a notice
+#       (the rule was already enforced or the PR is gone).
+#
+# D — author is not actually a bot but the filter mis-fires:
+#     - Filter is conservative: only triggers on
+#       `user.type == 'Bot'`, `login` ends with `[bot]`, or
+#       known bot logins (`molecule-ai[bot]`, `app/molecule-ai`).
+#       Human PRs slip through unaffected. If a NEW bot login
+#       starts shipping main-PRs, add it to the filter.

+ * PurchaseSuccessModal — demo-only post-purchase confirmation.
+ *
+ * Mounted on the canvas root (`app/page.tsx`). On first paint it inspects
+ * `?purchase_success=1[&item=<name>]` on the current URL. If present, it
+ * renders a centred modal styled after `ConfirmDialog`, schedules a 5s
+ * auto-dismiss, and rewrites the URL via `history.replaceState` to drop
+ * the params so a refresh after dismiss does NOT re-show the modal.
+ *
+ * Mock for the funding demo — there is no real billing surface behind
+ * this. The marketplace "Purchase" button on the landing page redirects
+ * here with the params; this modal is the only thing the user sees of
+ * the "transaction".
+ *
+ * Styling matches the warm-paper @theme tokens (surface-sunken / line /
+ * ink / good) so it tracks light + dark without per-mode overrides.

+# ADR-002: Local-build mode signalled by `MOLECULE_IMAGE_REGISTRY` presence
+
+* Status: Accepted (2026-05-07)
+* Issue: #63 (closes Task #194)
+* Decision: Hongming (CTO) + Claude Opus 4.7 (implementation)
+
+## Context
+
+Pre-2026-05-06, every Molecule deployment — both production tenants and OSS contributor laptops — pulled workspace-template-* container images from `ghcr.io/molecule-ai/`. Production tenants additionally set `MOLECULE_IMAGE_REGISTRY` to an AWS ECR mirror via Railway env / EC2 user-data, but the OSS default was the upstream GHCR org.
+
+On 2026-05-06 the `Molecule-AI` GitHub org was suspended (saved memory: `feedback_github_botring_fingerprint`). GHCR now returns **403 Forbidden** for every `molecule-ai/workspace-template-*` manifest. OSS contributors who clone `molecule-core` and run `go run ./workspace-server/cmd/server` cannot provision a workspace — every first provision fails with:
+
+```
+docker image "ghcr.io/molecule-ai/workspace-template-claude-code:latest" not found after pull attempt
+```
+
+Production tenants are unaffected (their `MOLECULE_IMAGE_REGISTRY` points at ECR, which we still control), but OSS onboarding is broken. Workspace template repos are intentionally separate from `molecule-core` (each runtime is OSS-shape and forkable), and they are mirrored to Gitea (`https://git.moleculesai.app/molecule-ai/molecule-ai-workspace-template-<runtime>`) — but the provisioner has no path that consumes Gitea source directly.
+
+## Decision
+
+When `MOLECULE_IMAGE_REGISTRY` is **unset** (or empty), the provisioner switches to a **local-build mode** that:
+
+1. Looks up the workspace-template repo's HEAD sha on Gitea via a single API call.
+2. Checks whether a SHA-pinned local image (`molecule-local/workspace-template-<runtime>:<sha12>`) already exists; if so, reuses it.
+3. Otherwise shallow-clones the repo into `~/.cache/molecule/workspace-template-build/<runtime>/<sha12>/` and runs `docker build --platform=linux/amd64 -t <tag> .`.
+4. Hands the SHA-pinned tag to Docker for ContainerCreate, bypassing the registry-pull path entirely.
+
+When `MOLECULE_IMAGE_REGISTRY` is **set**, behavior is unchanged: pull the image from that registry. Existing prod tenants and self-hosters who mirror to a private registry are not affected.
+
+## Consequences
+
+### Positive
+
+* **Zero-config OSS onboarding** — `git clone molecule-core && go run ./workspace-server/cmd/server` boots end-to-end without any registry credentials.
+* **Production tenants protected** — same env var, same semantics in SaaS-mode. Migration is a no-op.
+* **No new env var** — extending an existing var's semantics ("where to pull, OR build locally if absent") rather than introducing `MOLECULE_LOCAL_BUILD=1` keeps the surface small.
+* **SHA-pinned cache** — repeat builds are O(API-call); only template-repo HEAD changes invalidate.
+* **Production-parity image** — amd64 emulation on Apple Silicon honours `feedback_local_must_mimic_production`. The provisioner's existing `defaultImagePlatform()` already forces amd64 for parity; building amd64 locally lets that decision stay consistent.
+
+### Negative
+
+* **Conflates two concerns** — `MOLECULE_IMAGE_REGISTRY` now signals BOTH "where to pull" AND "build locally if absent." A future operator who unsets it expecting a hard error will instead get a slow first-provision. Documented in the runbook.
+* **First-provision is slow on Apple Silicon** — 5–10 min via QEMU emulation on the cold path. Mitigated by SHA-cache (subsequent runs are <1s lookup + 0s build).
+* **Coverage gap** — only 4 of 9 runtimes are mirrored to Gitea today (`claude-code`, `hermes`, `langgraph`, `autogen`). The other 5 fail with an actionable "not mirrored" error. Mirroring those repos is a separate task.
+* **Implicit trust boundary** — operator running `go run` implicitly trusts `molecule-ai/molecule-ai-workspace-template-*` repos on Gitea. This is the same trust they would extend to the GHCR images today; not a new attack surface.
+
+## Alternatives considered
+
+1. **New env var `MOLECULE_LOCAL_BUILD=1`** — explicit, but requires OSS contributors to know it exists. Violates the zero-config goal.
+2. **Push pre-built images to a Gitea container registry, mirror tag from upstream** — operationally cleaner but: (a) Gitea's container-registry add-on isn't deployed on the operator host, (b) defeats the OSS-contributor goal of "hack on the source, see your changes," since they'd still pull a stale image.
+3. **Embed Dockerfiles in molecule-core itself, drop the standalone template repos** — would work but breaks the OSS-shape principle; templates are intentionally separable, anyone-can-fork artifacts.
+4. **Build native arch on Apple Silicon (arm64) and drop the platform pin in local-mode** — fast, but creates `linux/arm64` images that diverge from the amd64-only prod runtime. Local-vs-prod debug behavior would diverge. Rejected per `feedback_local_must_mimic_production`.
+
+## Security review
+
+* **Gitea repo URL allowlist** — runtime name must be in the `knownRuntimes` allowlist (defence-in-depth against a future code path that lets cfg.Runtime carry untrusted input). Repo prefix is hardcoded to `https://git.moleculesai.app/molecule-ai/molecule-ai-workspace-template-`; forks can override via `MOLECULE_LOCAL_TEMPLATE_REPO_PREFIX` (opt-in, default off).
+* **Token handling** — clones are anonymous over HTTPS by default (templates are public). `MOLECULE_GITEA_TOKEN`, if set, is passed via URL userinfo for the clone and as `Authorization: token` for the API call. The token is **masked in every log line** via `maskTokenInURL` / `maskTokenInString` and never appears in the cache dir path.
+* **No silent fallback** — if Gitea is unreachable or the runtime isn't mirrored, we return a clear error mentioning the repo URL and the missing runtime. We **never** fall back to GHCR/ECR (that would be a confusing bug for an OSS contributor who happened to have stale ECR creds in their docker config).
+* **Build-arg injection** — `docker build` is invoked with NO `--build-arg` from external input. Dockerfile is consumed as-is.
+* **Cache poisoning** — cache key is the Gitea HEAD sha + Dockerfile content; a force-push to the template repo's main branch regenerates the key on next run. Cache dir is per-user (`$HOME/.cache`), so cross-user attacks aren't relevant in single-user dev mode.
+
+## Versioning + back-compat
+
+* Existing prod tenants set `MOLECULE_IMAGE_REGISTRY=<ECR url>` → unchanged behavior.
+* Existing local installs that set the var → unchanged behavior.
+* Existing local installs that don't set it → switch to local-build path. Migration: none required (additive); first provision will take 5–10 min instead of failing.
+* No deprecations.

 # Local Development
 
+## Workspace Template Images: Local-Build Mode (Issue #63)
+
+OSS contributors who run `molecule-core` locally do **not** need to authenticate to GHCR or AWS ECR. When the `MOLECULE_IMAGE_REGISTRY` env var is **unset**, the platform automatically:
+
+1. Looks up the HEAD sha of `https://git.moleculesai.app/molecule-ai/molecule-ai-workspace-template-<runtime>` (single API call, no clone).
+2. If a local image tagged `molecule-local/workspace-template-<runtime>:<sha12>` already exists, reuses it (cache hit).
+3. Otherwise, shallow-clones the repo into `~/.cache/molecule/workspace-template-build/<runtime>/<sha12>/` and runs `docker build --platform=linux/amd64 -t <tag> .`.
+4. Hands the SHA-pinned tag to Docker for `ContainerCreate`.
+
+**First-provision build time:** 5–10 min on Apple Silicon (amd64 emulation). Subsequent provisions hit the cache and start in seconds. Cache is invalidated automatically when the template repo's HEAD moves.
+
+**Currently mirrored on Gitea:** `claude-code`, `hermes`, `langgraph`, `autogen`. Other runtimes (`crewai`, `deepagents`, `codex`, `gemini-cli`, `openclaw`) fail with an actionable "not mirrored to Gitea" error pointing at the missing repo.
+
+**Production tenants are unaffected** — every prod tenant sets `MOLECULE_IMAGE_REGISTRY` to its private ECR mirror via Railway env / EC2 user-data, so the SaaS pull path stays identical.
+
+### Environment overrides
+
+| Var | Default | Use case |
+|-----|---------|----------|
+| `MOLECULE_IMAGE_REGISTRY` | (unset) | Set to a real registry URL to switch from local-build to SaaS-pull mode. |
+| `MOLECULE_LOCAL_BUILD_CACHE` | `~/.cache/molecule/workspace-template-build` | Override cache directory. |
+| `MOLECULE_LOCAL_TEMPLATE_REPO_PREFIX` | `https://git.moleculesai.app/molecule-ai/molecule-ai-workspace-template-` | Point at a fork. |
+| `MOLECULE_GITEA_TOKEN` | (unset) | Required only if your fork has private template repos. |
+
+### Verifying a switch from the GHCR-retag stopgap
+
+Pre-fix, OSS contributors worked around the suspended GHCR org by manually retagging an `:latest` image. After this change, that workaround is **redundant**: simply unset `MOLECULE_IMAGE_REGISTRY` (or leave it unset), boot the platform, and provision a workspace. Logs will show:
+
+```
+Provisioner: local-build mode → using locally-built image molecule-local/workspace-template-claude-code:<sha12> for runtime claude-code
+local-build: cloning https://git.moleculesai.app/molecule-ai/molecule-ai-workspace-template-claude-code → ...
+local-build: docker build done in <duration>
+```
+
+If you still see `ghcr.io/molecule-ai/...` in the boot log, double-check `env | grep MOLECULE_IMAGE_REGISTRY` — a stale shell export from the pre-fix workaround could keep SaaS-mode active.

+
+> Companion to issue #64 ("RATE_LIMIT default re-tune analysis"). After

+> req/min/key default is correct, too tight, or too loose.
+
+## What's already exposed
+
+The workspace-server's existing Prometheus middleware
+(`workspace-server/internal/metrics/metrics.go`) tracks every request
+on every path:
+
+```
+molecule_http_requests_total{method, path, status}      counter
+molecule_http_request_duration_seconds_total{method,path,status}  counter
+```
+
+Path is the matched route pattern (`/workspaces/:id/activity` etc), so
+high-cardinality workspace UUIDs do not explode the label space.
+
+The rate limiter middleware (#60, `workspace-server/internal/middleware/ratelimit.go`)
+also stamps every response with `X-RateLimit-Limit`, `X-RateLimit-Remaining`,
+and `X-RateLimit-Reset`. Operators with browser-side or proxy-side
+header capture can read per-request bucket state directly.
+
+No new instrumentation is needed for #64's acceptance criteria. The
+metric surface is sufficient — this runbook just collects the queries.
+
+## Queries to run after #60 deploys
+
+### 1. Is the bucket actually firing 429s?
+
+```promql
+sum(rate(molecule_http_requests_total{status="429"}[5m]))
+```
+
+If this is zero on a given tenant, the bucket isn't being hit. If it's
+sustained > 1/min, dig in.
+
+### 2. Which routes attract 429s?
+
+```promql
+topk(
+  10,
+  sum by (path) (
+    rate(molecule_http_requests_total{status="429"}[5m])
+  )
+)
+```
+
+Expected shape post-#60:
+- `/workspaces/:id/activity` should be near zero — the canvas no longer
+  polls it on a 30s/60s/5s cadence (PRs #69 / #71 / #76).
+- Probe / health / heartbeat paths should be ~0 (those routes have a
+  separate IP-fallback bucket).
+
+If `/workspaces/:id/activity` 429s persist post-PRs-69/71/76 deploy, the
+canvas isn't running the WS-subscriber path — investigate WS health
+on that tenant.
+
+### 3. Per-bucket-key inference (no direct exposure today)
+
+The bucket map itself is in-memory only; we deliberately do **not**
+expose `org:<uuid>` ↔ remaining-tokens because that map can include
+SHA-256 hashes of bearer tokens. A tenant that wants per-key visibility
+should rely on response headers (`X-RateLimit-Remaining` on every
+response from a given session is the bucket's view of that session).
+
+If you genuinely need server-side per-bucket counts for triage,
+file a follow-up — the proper shape is a `/internal/ratelimit-stats`
+endpoint that emits **counts per key prefix only** (e.g. `org:`, `tok:`,
+`ip:`), never the key payloads. Don't roll that ad-hoc; it's a security
+review surface.
+
+## Decision tree for the re-tune
+
+After 14 days of production traffic on a tenant, look at the queries
+above and walk this tree:
+
+```
+Q1: Is the 429 rate sustained > 0.1/sec on any tenant?
+  ├─ NO  → The 600 default has comfortable headroom. Either keep it,
+  │        or lower it carefully (300) ONLY if you have a documented
+  │        reason (e.g. a misbehaving client we want to throttle harder).
+  │        Default to "no change" — see #64 for the math.
+  └─ YES → Q2.
+
+Q2: Is the 429 rate concentrated on ONE tenant or spread across many?
+  ├─ ONE tenant → Operator override: set RATE_LIMIT=1200 or 1800 on that
+  │               tenant's box. Document in the tenant's ops note. The
+  │               default does not need to change.
+  └─ MANY tenants → Q3.
+
+Q3: Are the 429s on a route that polls (e.g. /activity / /peers)?
+  ├─ YES → Confirm PRs #69, #71, #76 have actually deployed to those
+  │         tenants. If they have and 429s persist, the canvas may have
+  │         a regression — do not raise RATE_LIMIT. File a canvas issue.
+  └─ NO  → 429s on mutating routes mean genuine load. Raise the default
+            to 1200 in `workspace-server/internal/router/router.go:54`.
+            Same PR should attach: the metric chart, the time window,
+            and a paragraph explaining what changed in our traffic shape.
+```
+
+## Alert rule template (drop-in for Prometheus)
+
+```yaml
+# Sustained 429s — file is the SLO trip-wire. If this fires, walk the
+# decision tree above. NB: the issue#64 acceptance criterion is "two
+# weeks of metrics"; this alert is the inverse — it tells you something
+# changed before the two weeks are up.
+groups:
+  - name: workspace-server-ratelimit
+    rules:
+      - alert: WorkspaceServerRateLimit429Sustained
+        expr: |
+          sum by (instance) (
+            rate(molecule_http_requests_total{status="429"}[10m])
+          ) > 0.1
+        for: 30m
+        labels:
+          severity: warning
+          owner: workspace-server
+        annotations:
+          summary: "{{ $labels.instance }} sustained 429s — see ratelimit-observability runbook"
+          runbook: "https://git.moleculesai.app/molecule-ai/molecule-core/blob/main/docs/engineering/ratelimit-observability.md"
+```
+
+Threshold rationale: 0.1 req/s = 6/min sustained over 10min. Below
+that, a 429 is almost certainly a transient burst that the canvas's
+retry-once handler at `canvas/src/lib/api.ts:55` already absorbs. The
+30m `for:` keeps the alert from chattering on a brief blip.
+
+## Companion probe script
+
+For one-off triage when an operator can reproduce the problem in their
+own browser, `scripts/edge-429-probe.sh` (#62) reproduces a canvas-
+sized burst against a tenant subdomain and dumps each 429's response
+shape so the operator can distinguish workspace-server bucket overflow
+from CF/Vercel edge rate-limiting without dashboard access.
+
+```sh
+./scripts/edge-429-probe.sh hongming.moleculesai.app --burst 80 --out /tmp/edge.txt
+```
+
+The script's report header explains how to read the output.

+# Runbook — Handlers Postgres Integration port-collision substrate
+
+**Status:** Resolved 2026-05-08 (PR for class B Hongming-owned CICD red sweep).
+
+## Symptom
+
+`Handlers Postgres Integration` workflow fails on staging push and PRs.
+Step `Apply migrations to Postgres service` shows:
+
+```
+psql: error: connection to server at "127.0.0.1", port 5432 failed: Connection refused
+```
+
+Job-cleanup step further down logs:
+
+```
+Cleaning up services for job Handlers Postgres Integration
+failed to remove container: Error response from daemon: No such container: <id>
+```
+
+…confirming the postgres service container was already gone before
+cleanup ran.
+
+## Root cause
+
+Our Gitea act_runner (operator host `5.78.80.188`,
+`/opt/molecule/runners/config.yaml`) sets:
+
+```yaml
+container:
+  network: host
+```
+
+…which act_runner applies to BOTH the job container AND every
+`services:` container in a workflow. Multiple workflow instances
+running concurrently across the 16 parallel runners each try to bind
+postgres on `0.0.0.0:5432`. The first wins; subsequent instances exit
+immediately with:
+
+```
+LOG:  could not bind IPv4 address "0.0.0.0": Address in use
+HINT: Is another postmaster already running on port 5432?
+FATAL: could not create any TCP/IP sockets
+```
+
+act_runner sets `AutoRemove:true` on service containers, so Docker
+garbage-collects them as soon as they exit. By the time the migrations
+step runs `pg_isready` / `psql`, the container is gone and connection
+refused.
+
+Reproduction (operator host):
+
+```bash
+docker run --rm -d --name pg-A --network host \
+  -e POSTGRES_PASSWORD=test postgres:15-alpine
+docker run -d --name pg-B --network host \
+  -e POSTGRES_PASSWORD=test postgres:15-alpine
+docker logs pg-B   # FATAL: could not create any TCP/IP sockets
+```
+
+## Why per-job override doesn't work
+
+The natural fix — per-job `container.network` override — is silently
+ignored by act_runner. The runner log emits:
+
+```
+--network and --net in the options will be ignored.
+```
+
+This is a documented act_runner constraint: container network is a
+runner-wide setting, not per-job. Source: gitea/act_runner config docs
++ vegardit/docker-gitea-act-runner issue #7.
+
+Flipping the global `container.network` to `bridge` would break every
+other workflow in the repo (cache server discovery,
+`molecule-monorepo-net` peer access during integration tests, etc.) —
+unacceptable blast radius for a per-test bug.
+
+## Fix shape
+
+`handlers-postgres-integration.yml` no longer uses `services: postgres:`.
+It launches a sibling postgres container manually on the existing
+`molecule-monorepo-net` bridge network with a per-run unique name:
+
+```yaml
+env:
+  PG_NAME: pg-handlers-${{ github.run_id }}-${{ github.run_attempt }}
+  PG_NETWORK: molecule-monorepo-net
+
+steps:
+  - name: Start sibling Postgres on bridge network
+    run: |
+      docker run -d --name "${PG_NAME}" --network "${PG_NETWORK}" \
+        ...
+        postgres:15-alpine
+      PG_HOST=$(docker inspect "${PG_NAME}" \
+        --format "{{(index .NetworkSettings.Networks \"${PG_NETWORK}\").IPAddress}}")
+      echo "PG_HOST=${PG_HOST}" >> "$GITHUB_ENV"
+
+  # … migrations + tests use ${PG_HOST}, not 127.0.0.1 …
+
+  - if: always() && …
+    name: Stop sibling Postgres
+    run: docker rm -f "${PG_NAME}" || true
+```
+
+The host-net job container can reach a bridge-net container via the
+bridge IP directly (verified manually, 2026-05-08). Two parallel runs
+use different names + different bridge IPs — no collision.
+
+## Future-proofing
+
+Other workflows that hit the same shape (any `services:` with a
+fixed-port image) will exhibit the same failure mode under
+host-network runner config. Translate using this same pattern:
+
+1. Drop the `services:` block.
+2. Use `${{ github.run_id }}-${{ github.run_attempt }}` for unique
+   container name.
+3. Launch on `molecule-monorepo-net` (already trusted bridge in
+   `docker-compose.infra.yml`).
+4. Read back the bridge IP via `docker inspect` and export as a step env.
+5. `if: always()` cleanup step at the end.
+
+If the count of such workflows grows, factor into a composite action
+(`./.github/actions/sibling-postgres`) so the substrate logic lives
+in one place.

+# Issue molecule-core#62. The post-#60 verification step asks an
