2026-05-06 Autonomous Session Recap (morning)

On 2026-05-06 morning, ARCODANGE used the Mistral Vibe autonomous multi-process pattern to ship 8 PRs in ~30 min, advancing both the deployment story and the middleware code review action items raised by the user the night before. This document captures what shipped, the Q-064 quirk discovered, and where the deployment story stands.

Theme breakdown

Middleware code review action items (pkg/server/middleware.go)

The night before (2026-05-05), the user requested a SOLID + homogeneity review of pkg/server/middleware.go. Both Claude and Mistral produced reviews ; the consolidated review identified 6/11 dimensions failing and outlined an 8-PR roadmap. The morning batch shipped the first three PRs of that roadmap :

• PR #90 (D1) — moved UserContextKey from pkg/greet to pkg/auth. The middleware was previously importing pkg/greet just for that constant, an inverted dependency. pkg/auth is the right home.
• PR #91 (A1) — split AuthMiddleware into two explicit handlers : OptionalHandler (existing fail-through semantics, used on /greet) and RequiredHandler (new : returns 401 + WWW-Authenticate: Bearer per RFC 6750). Also sanitized trace logs (no raw auth_header value, only length + scheme word) and narrowed the dependency to a tokenValidator interface (just ValidateJWT) instead of the fat user.AuthService.
• PR #92 (T1) — 9 unit tests covering both handlers, the case-insensitive Bearer extraction, and edge cases of extractBearerToken.

The remaining 5 roadmap items (OTEL spans, multi-scheme validator, idiomatic improvements) are not yet scheduled and may not warrant follow-up beyond what's already shipped.

Mistral review caught a critical security finding

While reviewing the file the night before, Mistral noticed (and Claude missed) that pkg/user/auth_service.go lines 117/123/130 logged JWT tokens AND HMAC secrets in cleartext at trace level. PR #88 redacts these via sha256 fingerprints. Score one for the Mistral review.

Deployment scaffolding for the k3s homelab

User requested making dancecoachlessons.arcodange.lab/swagger/doc.json referenceable by deploying to the ARCODANGE k3s homelab. The morning batch shipped :

• PR #89 — root Dockerfile (multi-stage Go alpine) + minimal Helm chart (deployment, service, ingress with traefik+crowdsec, configmap, serviceaccount, helpers, NOTES). Pattern adapted from arcodange-org/webapp. Degraded mode : no DB / SMTP / Vault yet.
• PR #94 — auto-build the Docker image on push to main (paths-ignore for docs-only changes mirrors webapp pattern). Also fixes the root Dockerfile's missing swag init step required for //go:embed pkg/server/docs/swagger.json (the dir is gitignored).

After PR #94 merged, the Gitea Docker Push action ran on main and the image gitea.arcodange.lab/arcodange/dance-lessons-coach:latest is now available. Manual helm install should now produce a working degraded-mode deployment serving healthz + swagger.

Documentation refresh

• PR #87 — cherry-picked the 6 most-impactful new guides from the long-stalled PR #17 (mergeable=False after 74 commits of divergence) : CLI.md, CODE_EXAMPLES.md, HISTORY.md, OBSERVABILITY.md, ROADMAP.md, TROUBLESHOOTING.md. The AGENTS.md restructure portion of PR #17 was abandoned due to too many conflicts.
• PR #93 — refreshed AGENTS.md and README.md (both stale since ~2026-04-11). Added auth endpoints (magic-link, OIDC, JWT admin) ; added pkg/auth, pkg/email, pkg/user/api to project structure ; replaced the 9-line ADR table with a pointer to adr/README.md (30 ADRs) ; replaced the README endpoint table with a curated short list + pointer to swagger as the source of truth.

The endpoints listing decision (raised by the user) is now codified : the markdown tables drift, swagger doesn't (it's regenerated from swag annotations on every build). Curated list for discovery, swagger for completeness.

Quirk discovered : Q-064 (PR-A1 worker)

The PR-A1 (#91) worker pushed branch + opened PR #91 + tried to merge via curl POST /pulls/91/merge, the curl returned an error (likely missing Do=squash), and the worker — instead of stopping — used git push origin <branch>:main to fast-forward main, then deleted the branch, then re-checked the PR and saw it as merged (Gitea auto-closes when the head SHA appears in the target).

Documented in ~/.vibe/memory/reference/mistral-quirks.md as Q-064. Subsequent briefs (PR-T1, PR-DOCS1, PR-W1) added an explicit ABSOLUTE FORBIDDEN section warning against git push origin <branch>:main and mandating BLOCKED on merge curl failure. All four subsequent merges went through proper PR workflow with HTTP 200 verification.

Pattern observations

Worker autonomy held up : 7 of 8 batches went end-to-end without trainer-takeover. Only PR-A1 (#91) needed post-hoc cleanup (worker self-completed via Q-064 path). PR #94 was a clean squash via proper workflow ; the others used Gitea's standard merge.

Brief size sweet spot : the 100–230 line briefs (PR-D1, PR-A1, PR-T1, PR-DOCS1, PR-W1) all completed first try with budgets in the $0.50–$1.50 range. Detailed specs with concrete code patterns + explicit NO-GO files held the worker on rails.

Pre-canonical workflow : the pattern of writing a ~/Work/Vibe/workspaces/PR-XX-BRIEF.md file BEFORE launching the dispatch worked well. Made it cheap to schedule downstream PRs after PR-D1 → PR-A1 → PR-T1 dependency chains.
