Session 0075.0 — Transcript

App: ohm Start: 2026-06-05T12-45 (PST) End: 2026-06-05T13-21 (PST) Type: coding Status: FINALIZED Driver: Ben Stull (with Claude Opus 4.8) Outcome: §22 slice S2 shipped to main as v0.41.0 (PR #20 merged).

Launch prompt

Goal: §22 S2 — next slice of the three-tier (deployment→project→collection)
refactor, per the three-tier design doc / roadmap. Continue from S1 (collection
grain, mig 029, shipped v0.40.0).

(/goal S2 set a Stop-hook gate on the condition "S2".)

Plan

Goal: §22 S2 — Create & navigate a second collection (per docs/design/2026-06-05-three-tier-projects-collections.md Part E). Continues S1 (collection grain, mig 029, v0.40.0). Acceptance gate @S2 = scenario C3.6 (anonymous reader of an empty public collection catalog → empty catalog, no propose action, sign-in prompt).

Usable end-state: an admin creates a second collection beside the default one; it is navigable + proposable. Slice surfaces:

1. Registry mirror reads .collection.yaml manifests inside each project's content repo (beyond the seeded default collection).
2. create-collection endpoint (bot-commit-wrapped; authorized by deployment owner/admin for now — scoped roles are S3).
3. Project collection-directory at /p/<project>/ (2+ collections → list; exactly one visible → keep the S1 redirect).
4. Collection-scoped serve + propose under /p/<project>/c/<collection>/, incl. the C3.6 anonymous empty-catalog state.

Plan doc: docs/design/plans/2026-06-05-s2-second-collection.md. Release: minor bump (new functionality, non-breaking) + CHANGELOG entry.

Pre-state

• main clean at 4ffff6b, v0.40.0 (S1 / mig 029 shipped via PR #19).
• A collections table exists; entries keyed (collection_id, slug); one seeded default collection per project. Serving was project-scoped (collection = default); the .collection.yaml reader + collection-aware serving were S2.
• Backend: FastAPI + SQLite under backend/ (.venv, pytest). Frontend: React + react-router + vitest under frontend/.

Turn-by-turn arc

1. Session gate + claim. Classified as a coding session; ran wgl-session-coding-init, claimed ohm session 0075 (no other in-flight sessions). Verified a clean pushed main baseline @ v0.40.0.
2. Orient on S2. Read the design doc Part E (slice S2) + the Part C scenarios. Pinned the @S2 acceptance to C3.6 (anon empty public collection catalog).
3. Map the surfaces. An Explore subagent + direct reads mapped every S2 surface (registry mirror, collections.py, cache.refresh_meta_repo, bot.open_idea_pr, the propose helper, api_deployment.py, the frontend Catalog/App routes, api.js, the FakeGitea test fixture). Discovered the anonymous empty-state was already mostly present in Catalog.jsx — the real work was making the catalog/entry views collection-scoped plus the backend mirror/endpoint.
4. Write the plan (writing-plans skill) → docs/design/plans/2026-06-05-s2-second-collection.md, 10 TDD tasks. Logged the lower-confidence calls (create-collection commits straight to main; coarse S2 visibility; layout convention; S4-deferred empty states) to the Deferred-decisions section.
5. Execute (executing-plans skill), branch feat/s2-second-collection, one commit per task, TDD throughout (red → green → full-suite checkpoint):
   • T1 registry .collection.yaml discovery (parse_collection_manifest, _mirror_named_collections, immutable-type + visibility-inherit).
   • T2 collections.py read helpers (list_collections/get_collection/ subfolder_of).
   • T3 corpus mirror collection-grained (_refresh_collection_corpus).
   • T4 collection-scoped list/get/propose; refactored the project routes into _list_rfcs_for_collection/_get_rfc_for_collection/_propose_into_collection; bot.open_idea_pr gained rfcs_dir.
   • T5 create-collection (api_collections.py + bot.create_collection), mounted in api.py; extended FakeGitea to model directory listings so the content-repo walk is exercised end-to-end.
   • T6 frontend useCollectionId() + collection-scoped api.js (+ a fetch-mocked URL test).
   • T7 Catalog reads the active collection; propose modal threads it.
   • T8 CollectionDirectory at /p/<project>/ (1 → redirect, 2+ → list), replacing DefaultCollectionRedirect.
   • T9 @S2 acceptance test (C3.6): anon empty public collection → 200 [], propose rejected (401).
   • T10 release v0.41.0 (VERSION + package.json + CHANGELOG + design-doc "shipped" note).
6. Finish the branch (finishing-a-development-branch): both suites green (backend 478, frontend 26, build green); pushed the branch; created PR #20 via the Gitea API; merged it (merge commit 39ce54f); synced main, deleted the feature branch (local + remote).

Cut state

• main @ 39ce54f, v0.41.0, clean and pushed. No open PRs.
• Backend 478 passed; frontend 26 passed; frontend production build OK.
• New files: backend/app/api_collections.py, backend/tests/test_collection_registry.py, backend/tests/test_collection_helpers.py, backend/tests/test_collection_scoped_serve.py, backend/tests/test_collection_create_vertical.py, frontend/src/components/CollectionDirectory.jsx (+ test), frontend/src/api.collections.test.js, docs/design/plans/2026-06-05-s2-second-collection.md.
• Acceptance @S2 (C3.6) green. N=1 default-collection path unchanged.

Operator plate (decisions surfaced for review)

These were autonomous-mode calls (no clearly-wrong alternative; logged rather than gated):

1. create-collection commits straight to main of the content repo (no PR), then the registry mirror upserts the row. A collection is structural config and §22.2 makes the registry the source of truth. A PR-gated variant is possible if you want collection creation reviewed.
2. S2 collection visibility filtering is coarse — project read-gate + drop unlisted from enumeration. Full {owner, contributor} scope-role enforcement at the collection axis is S3.
3. Content-repo layout for a named collection: manifest at <subfolder>/.collection.yaml, entries at <subfolder>/rfcs/. Default collection (subfolder '') keeps the shipped repo-root rfcs/.
4. Role-keyed empty-state affordances ("Create your first collection", "Propose the first entry") are S4 — S2 ships only the anonymous empty catalog (C3.6) and a minimal directory list.

Next-session prompt

/goal S3 — scope-role enforcement across global/project/collection: the
four-layer most-permissive resolver over {owner, contributor} grants, every
write gate re-checked on the collection axis. Per
docs/design/2026-06-05-three-tier-projects-collections.md Part E (completes
@S3 = C1.1–C1.8).
