Session 0067.0 — Transcript

App: ohm (rfc-app framework) Date: 2026-06-03T20-31 → 2026-06-04T01-55 (PST) Goal: design and ship the backend half of §22 slice M3 (multi-project). Outcome: M3-backend Plan A merged to main (PR #11, 6c2bdb3, v0.33.0).

Launch prompt

Session-init → goal proposal selected §22 M3 (next slice after M1+M2). Operator invoked brainstorming to design it.

Plan

Goal: Design, plan, and implement the backend half of §22 slice M3 — multi-project registry mirror + data spine + runtime-config APIs. Roadmap: ohm-rfc/ROADMAP.md defers to the framework slicing plan in rfc-app/docs/design/multi-project-spec.md Part C.

Brainstorming decisions:

Scope split at the backend/frontend seam — this session = M3-backend; routing/branding/directory/switcher = a later M3-frontend spec.
Build the full initial_state/unreviewed review plumbing now.
Config hard cut: REGISTRY_REPO required, META_REPO removed.
Re-stamp default → config slug by rewriting project_id everywhere.
Registry mirror in a self-contained app/registry.py (Option A), driven by the existing webhook + Reconciler.sweep().

Planning discoveries (folded into the spec, reshaped the plan):

The re-stamp must be a Python startup step — pure-SQL migrations can't read DEFAULT_PROJECT_ID (same constraint that forced M1's seed_default_project).
The 12-table PK rebuild has a wide blast radius (~10 ON CONFLICT sites + every RFC/branch writer needs project_id threading; FK-bomb post-re-stamp). → Operator split M3-backend into Plan A (additive: registry mirror + APIs + review semantics + migration 027 — no rebuild/re-stamp/threading) and Plan B (PK rebuild + threading + re-stamp, before M4). This session executed Plan A.

Pre-session state

main carried M1 (schema spine) + M2 (project-scoped authz) + the v0.32.0 retire/§13 work + M3-0 (Tier-1 test harness, PR #9). Latest migration 026.
REGISTRY_REPO was wired into config but optional/unused; META_REPO was the live corpus source; projects table had no type/initial_state; no deployment table; no registry mirror; no /api/deployment.
Session-init found ~/.claude/wiggleverse.md was a dangling symlink (digest agent-context.md missing; only engineering/README.md present) — so the CLAUDE.md import was deferred at init, then resolved externally mid-session (committed 0f6b2b4).

Turn-by-turn arc

Init — claimed session 0067; flagged 3 stale --INPROGRESS sessions; clean main baseline; surfaced the dangling-symlink gap; proposed M3 as next goal.
Brainstorming — explored backend + frontend + §22 spec via parallel Explore agents; settled the 5 decisions above; wrote + committed the design spec (6f356d3), self-reviewed, operator-approved.
Writing-plans — read the real code (config/cache/webhooks/entry/api/bot/db/ gitea/migration 026/tests). Two coupling discoveries (env-read → Python re-stamp; PK-rebuild blast radius) → operator chose two plans, mirror first. Wrote + committed Plan A (9 TDD tasks, dd72f91).
Implementation (subagent-driven) — 9 tasks, each: implementer → spec-compliance review → code-quality review, fixes looped to approval. Real bugs caught by review and fixed: /api/projects/:id 500→404 for superusers on unknown id; non-dict registry entry → RegistryError; apply_registry made atomic; hygiene None content_repo guard; changelog draft→super-draft. Final whole-impl review (opus): ready to integrate.
Integrate — pushed branch; opened PR #11; Gitea blocked self-approval (422, expected); operator-authorized merge → main (6c2bdb3); branch deleted; merged main re-verified green (434); memory + MEMORY.md index updated.
Finalize — discussed JSONL-vs-curated transcript; filed a roadmap item (plugin PR #3) to source future transcripts from the session JSONL log (with secret-byte redaction + memory fallback); published this transcript.
PR cleanup — swept all open PRs: merged #10 (M3-frontend design spec) and #3 (plugin roadmap) to main; closed #8 (empty diff — §13/retire already on main) and #4 (superseded by #9) as stale. rfc-app now has zero open PRs. (Gitea token had repo/code scope but not issue scope — closes went through the /pulls endpoint; explanatory comments were 403'd, dispositions recorded here instead.)

Cut state (end of session)

M3-backend Plan A is merged to main — PR #11, merge 6c2bdb3, v0.33.0. Full suite 434 passed on merged main. Branch m3-backend-registry-spine deleted (local + remote).

Shipped: migration 027_projects_runtime_config.sql (additive — type/ initial_state on projects, deployment singleton, unreviewed/reviewed_* on cached_rfcs); app/registry.py (§22.2 parse/validate/apply, atomic); webhook + Reconciler.sweep + startup wiring (startup-fatal / running-tolerant); hard-cut META_REPO→REGISTRY_REPO (corpus mirror reads content_repo from the default project row); app/api_deployment.py (GET /api/deployment, GET /api/projects/:id, §22.5-gated); initial_state honoring at propose; mark-reviewed endpoint + ?unreviewed=true catalog filter; CHANGELOG 0.33.0 breaking upgrade block.

Per-task commit trail (each + its review fixes): T1 597f6bc · T2 2d9022b · T3 8f21dc5 · T4 27a0a04/f7bd466 · T5 cecc6c0/48fd6f9 · T6 c386b05/07e003e/e8ce3cd · T7 fe47eef/2fe2a71 · T8 76207bb/69fd0cb/8004b2a · T9 a2dc29a/f114af8. Plus CLAUDE.md org-context import 0f6b2b4. All on main via the PR #11 merge.

What lands on the operator's plate

M3-frontend is next — its design spec is now merged to main (PR #10); write its implementation plan against the real /api/deployment + /api/projects/:id shapes, then execute on the M3-0 Tier-1 harness. The feat/m3-frontend branch was kept (not deleted) in case in-flight work continues on it.
Deploy upgrade (when shipping v0.33.0): create a registry repo, author projects.yaml (id: default, content_repo = old META_REPO), set REGISTRY_REPO, remove META_REPO, add the registry webhook — per CHANGELOG 0.33.0 upgrade steps.
PRs all cleared — rfc-app has zero open PRs (stale #8/#4 closed; #10 merged). Plugin roadmap PR #3 merged.
Plan B (before M4): 12-table PK rebuild (migration 028) + project_id writer-threading (concrete sites: mark-reviewed + propose hardcode the default content_repo) + default→slug re-stamp + two-project isolation tests.
Roadmap landed: plugin PR #3 (merged) — generate future transcripts from the session JSONL log, with secret-byte redaction + memory fallback.

Prompt the operator can paste into the next session

Start a coding session on rfc-app (~/git/wiggleverse.org/ben.stull/rfc-app).
Read memory: MEMORY.md + project_rfc_app_multiproject.md. M3-backend Plan A is
merged to main (v0.33.0); the runtime APIs GET /api/deployment and
GET /api/projects/:id now exist. Next slice: M3-frontend — its design spec is
now on main (docs/superpowers/specs/2026-06-03-m3-frontend-design.md, merged via
PR #10). Write its implementation plan against those real API shapes, then
execute it via subagent-driven-development on the M3-0 Tier-1 harness (Vitest +
Playwright e2e). Coordinate the DEFAULT_PROJECT_ID / 308 ownership seam noted in
the spec. (PR backlog is clear — no triage needed.) Plan B (PK rebuild migration
028 + project_id writer-threading +
default→slug re-stamp) stays deferred until just before M4.
