From 229b1a902ac7e3207dde1214ce26cc76995711db Mon Sep 17 00:00:00 2001 From: devops-engineer Date: Thu, 7 May 2026 14:26:52 -0700 Subject: [PATCH 1/6] fix(ci): pre-clone manifest deps in harness-replays workflow (#173 followup) harness-replays.yml builds tenant-alpha + tenant-beta via tests/harness/ compose.yml using workspace-server/Dockerfile.tenant. Post-#173, that Dockerfile expects .tenant-bundle-deps/{workspace-configs-templates, org-templates,plugins} pre-cloned at the build context root. Sister PR #38 added the pre-clone step to publish-workspace-server-image.yml but missed harness-replays.yml. Symptoms: - main run #892 (2026-05-07T20:28:53Z): COPY .tenant-bundle-deps/plugins -> failed to calculate checksum ... not found. - staging run #964 (2026-05-07T20:41:52Z): hits the OLD in-image clone path (staging hasn't picked up the Dockerfile.tenant refactor yet via auto-sync) and fails on 'fatal: could not read Username for https://git.moleculesai.app' when cloning the first private workspace-template-* repo. Fix: add the same Pre-clone step to harness-replays.yml, mirroring publish-workspace-server-image.yml. Uses AUTO_SYNC_TOKEN (devops-engineer persona PAT) per feedback_per_agent_gitea_identity_default. Once auto-sync main->staging unblocks (sister agent fixing the 7-file conflict in flight), staging will inherit both this workflow fix AND the Dockerfile.tenant refactor atomically.

No production drift to fix today. Adds a regression-guard so the next path-filter / matrix refactor / workflow rename can't silently re-introduce the bug shape called out in saved memory feedback_branch_protection_check_name_parity: "Path filters … silently break branch protection because no job emits the protected sentinel status when path-filter returns false." New tools: - tools/branch-protection/check_name_parity.sh — extracts every required check name from apply.sh's heredocs, then for each name classifies the owning workflow as safe (no top-level paths:) / safe (per-step if-gates without top-level paths:) / unsafe (top-level paths: without per-step if-gates) / unsafe-mix (top-level paths: WITH per-step if-gates — the workflow may still skip entirely on path exclusion, leaving the gates dormant) / missing (no emitter at all). Special-cases codeql.yml's matrix- expanded `Analyze (${{ matrix.language }})`. - tools/branch-protection/test_check_name_parity.sh — 6 unit tests covering each classification: safe, unsafe-path-filter, missing, safe-with-per-step-gates, unsafe-mix, matrix-expansion. Each test builds a synthetic apply.sh + workflow file in a tmpdir, invokes the script, and asserts on exit code + stderr substring. Per feedback_assert_exact_not_substring the assertions pin specific classifications, not just non-zero exit. Wired into branch-protection-drift.yml so every PR touching .github/workflows/** runs the parity check; the existing daily schedule covers between-PR drift. The check is cheap (~1s) and runs without the admin token — only reads files in the checkout. Self- test step runs the unit tests on every invocation, so a regression in the script can't false-pass on production. Per BSD-vs-GNU portability hygiene: heredoc-marker extraction stays in plain awk + sed (no gawk-only `match()` array form), grep regex avoids `^` anchor for `if:` lines because real workflows use ` - if:` with the `-` step-marker between leading spaces and `if:` (the original anchor missed every workflow's per-step gates).

On Gitea this fails at the `gh pr create` step with `HTTP 405 Method Not Allowed (https://git.moleculesai.app/api/graphql)` — Gitea exposes no GraphQL endpoint, and the GitHub-CLI cannot ship PRs against Gitea. Verified failure mode in run 1117/job 0 (token logs at /tmp/log2.txt, run target /molecule-ai/molecule-core/actions/ runs/1117/jobs/0). The merge step succeeded and pushed auto-sync/main-1e1f4d63; the PR step failed with the 405. So every main push left an orphan auto-sync/* branch and a red CI status, with no PR to land it. Fix: the staging branch protection on Gitea (`enable_push: true`, `push_whitelist_usernames: [devops-engineer]`) already permits direct push from the devops-engineer persona. Drop the entire merge-queue PR architecture and replace with: 1. Checkout staging with secrets.AUTO_SYNC_TOKEN (devops-engineer persona token, NOT founder PAT — `feedback_per_agent_gitea_identity_default`). 2. `git fetch origin main` + ff-merge or no-ff merge. 3. `git push origin staging` directly. The AUTO_SYNC_TOKEN repo secret already exists (created 2026-05-07 14:00 alongside the staging push_whitelist update). Workflow name + job name unchanged → required-check name `Auto-sync main → staging / sync-staging (push)` keeps the same context, no branch-protection edits needed. Rejected alternatives (documented in workflow header): - Reuse PR architecture via Gitea REST: ~80 LOC of API plumbing for no benefit; direct push works. - GH_HOST=git.moleculesai.app: still calls /api/graphql, same 405; doesn't fix the root issue. - Custom JS action: external dep for a 5-line `git push`. Header comment in the workflow now documents: - What this workflow does (SSOT for staging advancing). - Why direct push (GitHub merge_queue → Gitea push_whitelist). - Identity and token (anti-bot-ring per saved memory). - Failure modes A–D with operator runbook for each. - Loop safety (push to staging doesn't fire push:main → no recursion). Verification plan: this fix-PR's merge to main is itself the trigger; watch the workflow run on the merge commit and on one follow-up trigger commit, expect both green.

An operator without CF/Vercel dashboard access can reproduce a canvas-sized burst against a tenant subdomain and read each 429's response shape — workspace-server bucket overflow (JSON body + X-RateLimit-* headers) is distinguishable from CF (cf-ray) and Vercel (x-vercel-id) by inspection of the report. Read-only, parallel via background subshells (no GNU parallel dependency), no credential use. Smoke-tested against example.com end-to-end. 2. docs/engineering/ratelimit-observability.md (closes the "metric-blocked" status of #64). The existing molecule_http_requests_total{path,status} counter + X-RateLimit-* response headers already cover #64's acceptance criterion ("watch metrics for two weeks"). The runbook collects the PromQL queries, a decision tree for the re-tune (keep / per-tenant override / change default), an alert rule template, and a hard "do not roll ad-hoc per-bucket-key exposure" note (in-memory map includes SHA-256 of bearer tokens — exposing it is a security review surface, file a follow-up if needed). Neither artifact changes runtime behaviour. Pure operational tooling.

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.
