LG-3 — CORE-Logos Studio: Contents tabs (Lexicon / Glosses / Morphology)

Date: 2026-06-14 Wave: read-only CORE-Logos Studio (L1–L5). Parent pack: docs/handoff/core-logos-studio-readonly-briefs-2026-06-14.md. Plan: docs/workbench/core-logos-studio-plan.md. Depends on: LG-2 merged (/logos route shell + the 10 Logos* TS interfaces already mirrored + NOT_YET_MIRRORED shrunk). Rebase on it. May be authored in parallel with LG-4, but merges sequentially with it (shared train files: routes.ts / App.tsx / api.ts / evidenceAddress.ts) — rebase-union + retest, Wave R/M discipline. Scope (hard): the three Contents tabs only — Lexicon, Glosses, Morphology. No Alignment tab (LG-4). No mutation affordances. Reads only GET /logos/packs/{id}/contents (LogosPackContents).

Non-negotiables

• No theater, no recompute. Render only fields the /logos/contents endpoint returns. Dangling-link flags reuse the LG-1 safety report's dangling_morphology_links — never recompute link integrity in React.
• Read-only; determinism (no nondeterministic ordering); doctrine gates green.

Build

Add three tabs to the existing /logos TabBar (pattern: src/app/packs/PacksRoute.tsx). Each list uses the shared primitives: src/design/components/VirtualizedList, src/design/components/SearchInput, src/design/hooks/useListNavigation.ts, with selection tokens.

Lexicon (LogosLexiconRow)

Columns: entry_id · surface · lemma · language · pos/part_of_speech · semantic_domains · morphology_id · provenance_ids · epistemic_status.

• Search over surface/lemma/domain; filter by epistemic_status; group by semantic domain.
• Flag rows whose morphology_id appears in the safety report's dangling_morphology_links (cross-reference, don't recompute).
• speculative is the expected default (ADR-0021) — label neutrally.

Glosses (LogosGlossRow)

Columns: gloss_id · lemma · gloss · pos · linked entry_ids · provenance_ids · epistemic_status. Link each gloss to its lexicon entries via entry_ids. Raw row available in a collapsible (raw).

Morphology (LogosMorphologyRow)

• Render the ordered operator chain in schema order: root → prefix_chain → stem → inflection → suffix_chain. Ordering is load-bearing (Semitic root / Koine grammar) — never re-sort.
• Link to the lexicon entry via morphology_id; flag dangling (same cross-reference to the safety report).

Evidence subjects (src/app/evidenceAddress.ts)

Add three subject kinds + address grammar (alongside the LG-2 logos_pack):

• logos_entry → logos:<pack_id>:entry:<entry_id>
• logos_gloss → logos:<pack_id>:gloss:<gloss_id>
• logos_morphology → logos:<pack_id>:morphology:<morphology_id> Each: union member, equality, encode/parse, right-inspector projection, copyable pointer, ?inspect= sync, chain-rail derivation. Round-trip tests in evidenceAddress.test.ts.

Acceptance / tests

• Render + filter + keyboard-nav tests for each tab against fixture LogosPackContents.
• Dangling-link flag test: a row flagged in the safety report shows the flag; others don't.
• Morphology order test: chain renders in schema order (assert against a known Hebrew entry, e.g. he-morph-008 suffix ים).
• evidenceAddress.test.ts — round-trip for all three new kinds.
• routes.test.tsx / schemaDrift / enumCoverage stay green. No new engine schemas (LG-2 mirrored them) — NOT_YET_MIRRORED untouched.
• pnpm build clean.
• Run the FULL pnpm exec vitest run before push — it must pass AND exit. The CI workbench-ui job gates on the whole suite; focused per-file runs miss a PR's own new test files and cross-cutting tests (LG-2 lesson: stale route-count assertions only surfaced in the full run, never the focused one).

Out of scope (separate brief)

• LG-4 — Alignment tab + holonomy-absent confirmation.
