+# 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.
+
+## Out of scope (separate brief)
+- **LG-4** — Alignment tab + holonomy-absent confirmation.

+# LG-4 — CORE-Logos Studio: Alignment tab (centerpiece) + holonomy-absent
+
+**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 mirrored). Rebase on it. May be authored in parallel with LG-3 but
+**merges sequentially** with it (shared train files: `routes.ts` / `App.tsx` /
+`api.ts` / `evidenceAddress.ts`) — rebase-union + retest.
+**Scope (hard):** the **Alignment** tab (the wave centerpiece) + confirming the
+honest holonomy-absent state. **No contents tabs (LG-3). No mutation.** Reads
+only `GET /logos/packs/{id}/alignment` (`list[LogosAlignmentRow]`).
+
+## Non-negotiables
+- **Determinism is the whole point.** Render with the existing **deterministic**
+  DAG primitive (`src/design/components/Dag/Dag.tsx`, layered longest-path via
+  `layout.ts`). **No force-directed / nondeterministic layout, no motion-as-
+  cognition.** A golden-file layout test is required (mirror
+  `Dag/Dag.layout.golden.json`).
+- No theater, no recompute. Render only the endpoint's fields.
+
+## Build
+
+### Alignment tab
+- Add an **Alignment** tab to the existing `/logos` `TabBar`. The trilingual
+  resonance graph (he → grc → en) is the strongest real data in the wave — make
+  it the centerpiece. Consumer pattern: `src/app/proposals/ProposalChainViewer.tsx`
+  (the existing `Dag` consumer).
+- Per-edge card / row (`LogosAlignmentRow`): `source_id` · `target_id` ·
+  `relation` · `weight` · `evidence_ids` · `target_pack_id` · **invalid-target
+  warning** when `invalid_target` is true.
+- **Surface the invalid targets honestly.** LG-1 reports 5 undeclared
+  `en-collapse-*` anchors (`breath/heart/holy/soul/time`) as `invalid_target` in
+  `grc_logos_cognition_v1`; the declared 3 (`love/justice/peace`) resolve. Show
+  the warning — do **not** hide or smooth it. This is a reviewer-visible "the
+  geometry tells the truth" moment, not a defect to mask.
+- Answer the plan's four questions in the tab: what does this Hebrew root align
+  with / what Greek relation carries the same pressure / what English surface
+  receives it / what evidence supports the edge (`evidence_ids`, e.g.
+  `John1:1` / `Gen1:1`).
+
+### Evidence subject (`src/app/evidenceAddress.ts`)
+- Add `logos_alignment_edge` → `logos:<pack_id>:alignment:<edge_id>`, where
+  `edge_id` is the LG-1 deterministic id
+  (`sha256(source|target|relation)[:16]`, already on `LogosAlignmentRow`).
+- Union member, equality, encode/parse, right-inspector projection, copyable
+  pointer, `?inspect=` sync, chain-rail derivation. Round-trip test.
+
+### Holonomy — confirm absent-state (no new tab)
+- **No Holonomy tab, no proof card, no success state.** Overview already shows
+  `holonomy_case_count` 0 + `missing_evidence` (LG-2); Safety shows
+  `missing_holonomy_refs` `unknown`. LG-4's only holonomy work is a guard that
+  **no holonomy proof affordance leaks in** — add a test asserting the `/logos`
+  surface renders no holonomy success/proof element. (Real holonomy cards are
+  the future W-Holonomy wave once `holonomy.jsonl` exists.)
+
+## Acceptance / tests
+- **Golden-file layout test** for the alignment DAG (deterministic node/edge
+  layout; mirror the `Dag.layout.golden.json` pattern).
+- Invalid-target render test: an `invalid_target` edge shows the warning; a
+  resolved edge does not. Assert the 5 undeclared `en-collapse-*` anchors warn.
+- `evidenceAddress.test.ts` — `logos_alignment_edge` round-trip.
+- Holonomy-absent guard: no proof/success element on the `/logos` surface.
+- `routes.test.tsx` / `schemaDrift` / `enumCoverage` stay green. **No new engine
+  schemas** — `NOT_YET_MIRRORED` untouched.
+- `pnpm build` clean.
+
+## Out of scope (separate brief)
+- **LG-3** — Lexicon / Glosses / Morphology contents tabs.
+- **W-Holonomy / W-Forge** — future waves (author `holonomy.jsonl`; universal
+  `ProposalArtifact` envelope + Patch Forge). Not this wave.
