Session 0085.0 — Transcript

App: ohm Start: 2026-06-07T16-55 (PST) Type: planning-and-executing Status: FINALIZED.

Launch prompt

/goal next → resume stored goal: SLICE-2 of configurable-collection-metadata — collection fields: schema + central metadata_schema.validate.

Pre-state

Repo ben.stull/rfc-app on clean, pushed main = 98c276a @ v0.47.0 (SLICE-1 sidecars shipped session 0084).
One stale in-flight transcript surfaced at claim: SESSION-0080 (--INPROGRESS from 2026-06-06), but sessions 0083/0084 finalized after it — almost certainly a crash orphan the SessionEnd hook didn't flag. Not adopted (not my work, no context, not annotated ENDED-UNFINALIZED); noted and proceeded (autonomous default).
Memory Next /goal: field said SLICE-2; design doc docs/design/2026-06-06-configurable-collection-metadata.md §7.2 is the spec.

Plan

Plan doc: docs/design/plans/2026-06-07-slice2-collection-field-schema.md (archived to ben/ohm-rfc:plans/).

DoD (design §7.2 SLICE-2): .collection.yaml fields: parsed + stored (rides in existing collections.config_json, no migration); metadata_schema.validate advisory at read / enforcement point for write (write endpoints land SLICE-4/5); schema served via GET …/collections/{id}; no-fields: collections unchanged (INV-5).

Steps: (1) new app/metadata_schema.py — lenient parse_fields + advisory validate (enum/tags/text); (2) registry.parse_collection_manifest reads fields: into config; (3) collections.get_collection unpacks fields from config_json → served by API; (4) cache._refresh_collection_corpus runs advisory validation, OR-ing into metadata_malformed (INV-3); (5) full suite green, bump 0.48.0 + CHANGELOG, PR + merge. TDD throughout.

Turn-by-turn arc

Classified the /goal next opening → planning-and-executing; ran wgl-planning-and-executing init: computed PST start, confirmed clean/pushed main, peeked in-flight (SESSION-0080 orphan), claimed session 0085.
Read the design doc + amended SPEC §22.4a + the SLICE-1 surfaces (metadata.py, entry.py extra, registry.py ingest, collections.py read, cache.py corpus mirror, api_collections.py). Confirmed schema field values land in Entry.extra (custom) / Entry.tags (tags), and that the .collection.yaml fields: block flows through parse_collection_manifest → CollectionEntry.config → collections.config_json — no migration needed.
Wrote the plan doc + seeded the transcript Plan block. Logged three deferred decisions (multi-enum=no; default-collection-fields out of scope; lenient schema parsing).
TDD: wrote tests/test_metadata_schema.py (19 cases), then app/metadata_schema.py → green.
Wired ingest: registry.parse_collection_manifest reads fields:; collections.get_collection unpacks _fields_from_config; extended test_collection_registry.py + test_collection_helpers.py → green.
Wired advisory validation in cache._refresh_collection_corpus (fetch schema once/collection, validate per entry, OR into metadata_malformed); extended test_metadata_cache.py (3 cases incl. INV-5/INV-7) → green.
Full backend suite: 601 passed. Bumped VERSION + package.json → 0.48.0, wrote CHANGELOG 0.48.0 (+ upgrade steps). Committed, pushed branch worktree-metadata-slice2-schema, created PR #32 (Gitea API), merged, synced main = 1bcf8aa, pruned branch.
Finalize: archived the plan to the content repo, updated memory + index, published this transcript.

Cut state

Origin main = 1bcf8aa @ v0.48.0; tree clean. Backend suite 601 green.
SLICE-2 complete (all DoD met). Write-boundary enforcement intentionally deferred to SLICE-4/5 (no edit endpoints yet). No deploy (3-minor undeployed gap vs OHM @0.46.1 — batched intentionally).

Outcome

SLICE-2 of configurable-collection-metadata shipped as v0.48.0 (PR #32, origin main = 1bcf8aa). New app/metadata_schema.py (lenient parse_fields

advisory validate); .collection.yaml fields: ingested via registry into collections.config_json; schema served on the collection API; advisory validation wired into the corpus mirror (metadata_malformed, INV-3). Backend suite green (601 passed). No DB migration. INV-5 (no-fields unchanged) tested.

Next: SLICE-3 — faceted left-pane filtering (read): list endpoint returns facet counts + honors filter params incl. malformed; left pane renders faceted groups with counts + tag-value search. Has a UI surface → Playwright E2E.

Deferred decisions

Q2 (multi-enum in v1?) → decided no: v1 field types are enum/tags/text only, per design §6.3. Unknown types ignored with a warning; multi-enum/ref deferred.
Default-collection fields: → out of SLICE-2: a default collection has no .collection.yaml, and the N=1 default is document with no fields (INV-5). Field schemas attach to named collections (with a manifest). A deployment wanting fields on its primary corpus declares a named collection. Consistent with the opt-in story; flagged so SLICE-3+ can revisit if needed.
Lenient schema parsing → a bad fields: block / field def is skipped with a warning, never fatal (INV-3 spirit), unlike structural manifest errors (type/visibility) which still raise.
Deploy deferred → SLICE-2 shipped v0.48.0 to main but was not deployed. OHM is live @0.46.1; three non-breaking framework minors (0.46.2, 0.47.0, 0.48.0) now accumulate undeployed — matching the prior slice sessions' pattern of batching the deploy. A dedicated flotilla deploy gesture should pick up the batch when the operator wants it.
Orphan session 0080 → surfaced at claim but not adopted/finalized (not this session's work, no context, not flagged ENDED-UNFINALIZED). Left for the operator to reconcile.
