-## Deferred Follow-Ups (Morphological Relations)

-### 1) Prefix derivations: avoid redundant `<derived_from>` with equation
-- Status: Deferred by request.
-- Current behavior: prefix cases can render both:
-  - `<derived_from>` `[[base]]`
-  - `[[prefix|decorated]] + [[base]] = [[source]] *(gloss)*`
-- Follow-up decision to implement later: for inferred prefix derivations, render only the equation and skip `<derived_from>`.

-### 2) Architecture doc table sync for Lexem POS section coverage
-- Status: Deferred by request.
-- Gap: `sectionsForLexemPos` in code includes `Morphology` for all Lexem POS, but the table in `/Users/annagorelova/work/Textfresser_vault/.obsidian/plugins/textfresser/src/documentaion/linguistics-and-prompt-smith-architecture.md` is only partially updated.
-- Follow-up to implement later: update all POS rows in the table so docs exactly match `section-config.ts`.

-  #: 2
-  Item: Remove vestigial apiProvider setting
-  Source: PR #22
-  What: apiProvider: "google" is a typed literal with one option. Settings tab renders a pointless

-  Descision: Rejected. apiProvider will be expanded later
-  ────────────────────────────────────────
-  #: 3

-  Source: PR #6 ideas
-  What: Two makeNodeSegmentId(node as any) casts in healer.ts and leaf-move-healing.ts. Fix with

 # Book Of Work
 
+## Pre-Extension Stabilization Backlog (Audit 2026-02-19)
+
+Source: local health-check run before new Textfresser feature work.
+
+### P0 (blockers)
+
+#### 0.1) Fix order-dependent unit tests caused by leaked module mocks
+- Symptom: tests pass in isolation but fail when specific files are run together.
+- Repro:
+  - `bun test --preload ./tests/unit/setup.ts tests/unit/textfresser/steps/propagate-generated-sections.test.ts tests/unit/textfresser/steps/generate-reencounter-sections.test.ts`
+  - `bun test --preload ./tests/unit/setup.ts tests/unit/textfresser/steps/propagate-generated-sections.test.ts tests/unit/textfresser/steps/decorate-attestation-separability.test.ts`
+- Root cause: top-level `mock.module(...)` in `/Users/annagorelova/work/Textfresser_vault/.obsidian/plugins/textfresser/tests/unit/textfresser/steps/propagate-generated-sections.test.ts` shadows real modules across the process.
+- Follow-up:
+  - Isolate mocks per test (or use scoped dynamic imports + restore discipline).
+  - Audit other top-level `mock.module(...)` users for similar bleed.
+
+#### 0.2) Restore `src/` TypeScript compile health
+- Current state: `bun x tsc --noEmit -skipLibCheck` reports production-code errors in `src/` (not only tests).
+- High-priority breakpoints:
+  - `/Users/annagorelova/work/Textfresser_vault/.obsidian/plugins/textfresser/src/commanders/librarian/codecs/locator/internal/from.ts`
+  - `/Users/annagorelova/work/Textfresser_vault/.obsidian/plugins/textfresser/src/commanders/librarian/commands/split-in-blocks.ts`
+  - `/Users/annagorelova/work/Textfresser_vault/.obsidian/plugins/textfresser/src/commanders/librarian/healer/library-tree/tree-action/bulk-vault-action-adapter/layers/library-scope/codecs/events/make-event-vault-scoped.ts`
+  - `/Users/annagorelova/work/Textfresser_vault/.obsidian/plugins/textfresser/src/managers/obsidian/behavior-manager/checkbox-behavior.ts`
+  - `/Users/annagorelova/work/Textfresser_vault/.obsidian/plugins/textfresser/src/managers/overlay-manager/index.ts`
+
+### P1 (stability + correctness)
+
+#### 1.1) Resolve stale separability-decoration tests vs current contract
+- Current implementation says no visual alias markers are added for multi-span separable verbs:
+  - `/Users/annagorelova/work/Textfresser_vault/.obsidian/plugins/textfresser/src/commanders/textfresser/commands/generate/steps/decorate-attestation-separability.ts`
+- Existing tests still expect `>` / `<` decorations:
+  - `/Users/annagorelova/work/Textfresser_vault/.obsidian/plugins/textfresser/tests/unit/textfresser/steps/decorate-attestation-separability.test.ts`
+- Decision needed: reintroduce marker behavior or update tests to the current no-marker design.
+
+#### 1.2) Make `typecheck:changed` script deterministic and actionable
+- Current script:
+  - `/Users/annagorelova/work/Textfresser_vault/.obsidian/plugins/textfresser/scripts/typecheck-changed.sh`
+- Issue: final `grep` can produce exit code 1 with no useful output (false-fail behavior for "no matched diagnostics").
+- Follow-up: preserve non-empty diagnostics and avoid grep-only exit semantics as the pass/fail source.
+
+#### 1.3) Return lint to green
+- Current state: `bun run lint` fails.
+- Notable error/warning hotspots:
+  - `/Users/annagorelova/work/Textfresser_vault/.obsidian/plugins/textfresser/src/commanders/textfresser/domain/propagation/note-adapter.ts`
+  - `/Users/annagorelova/work/Textfresser_vault/.obsidian/plugins/textfresser/src/commanders/textfresser/orchestration/lemma/execute-lemma-flow.ts`
+  - `/Users/annagorelova/work/Textfresser_vault/.obsidian/plugins/textfresser/src/commanders/textfresser/textfresser.ts`
+  - `/Users/annagorelova/work/Textfresser_vault/.obsidian/plugins/textfresser/src/stateless-helpers/wikilink.ts`
+
+### P2 (maintainability / debt)
+
+#### 2.1) Decompose large multi-responsibility modules
+- Largest active hotspots in runtime code:
+  - `/Users/annagorelova/work/Textfresser_vault/.obsidian/plugins/textfresser/src/commanders/textfresser/domain/propagation/note-adapter.ts`
+  - `/Users/annagorelova/work/Textfresser_vault/.obsidian/plugins/textfresser/src/commanders/textfresser/commands/generate/steps/generate-new-entry-sections.ts`
+  - `/Users/annagorelova/work/Textfresser_vault/.obsidian/plugins/textfresser/src/main.ts`
+- Follow-up: split parser/serializer/normalization/section-dispatch concerns into focused modules with targeted tests.
+
+#### 2.2) Reduce risky cast footprint in critical pathways
+- Health-check snapshot found high cast volume (`as any`, `as unknown as`, `@ts-expect-error`) across runtime and tests.
+- Start with runtime modules touched by P0/P1 fixes, then tighten tests.
+

+# Ideas to Consider
+
+## Deep Audit — Textfresser Generate Pipeline (2026-02-19)
+
+Source: automated codebase scan targeting duplication, dead code, type safety, testing gaps, and structural concerns in the generate/propagation pipeline.
+
+### P1 (correctness risk)
+
+#### 1) Two separate `parseEntryChunk` implementations with diverging behaviour
+- Files: `domain/dict-note/internal/parse.ts`, `domain/propagation/note-adapter.ts`
+- Both implement `parseEntryChunk(chunk, metaByEntryId)` walking the same chunk format. The propagation version is richer (typed section kinds, section sorting, sampled warnings) while dict-note's is simpler. Any on-disk format change must be applied in two places.
+- Fix: extract shared header/chunk parsing primitive into `dict-note/internal/`, each caller applies its own section-level enrichment.
+
+#### 2) Unguarded `as string` cast in `serialize-entry.ts`
+- File: `commands/generate/steps/serialize-entry.ts`
+- `noteMetadataHelper.upsert(fullMeta)` returns `string | Promise<string>`, result is cast `as string` without guard. `dictNoteHelper.serializeToString` has the correct guard-and-throw pattern.
+- Fix: use the same guard-and-throw approach or delegate to `dictNoteHelper.serializeToString`.
+
+### P2 (duplication / maintainability)
+
+#### 3) `trimTrailingNewlines` duplicated in two sibling files
+- Files: `steps/propagation-line-append.ts`, `steps/propagate-morphemes.ts`
+- Identical private function. Similarly, `findNextMorphologyMarkerOffset` ≈ `findNextBlockMarkerOffset`.
+- Fix: move both into `propagation-line-append.ts` (already imported by `propagate-morphemes.ts`).
+
+#### 4) `EntriesMetaSchema` duplicated across two parsers
+- Files: `domain/dict-note/internal/parse.ts`, `domain/propagation/note-adapter.ts`
+- Both define `z.object({ entries: z.record(z.record(z.unknown())).optional() }).passthrough()` with the same `as any` Zod v3/v4 bridge cast.
+- Fix: define once in `dict-note/internal/schema.ts` or `constants.ts`.
+
+#### 5) Entry-construction pattern duplicated across 3 propagation steps
+- Files: `propagate-morphemes.ts`, `propagate-inflections.ts`, `propagate-morphology-relations.ts`
+- All three inline the same 4-line pattern: compute `existingIds` → `dictEntryIdHelper.buildPrefix(...)` → `dictEntryIdHelper.build(...)` → assemble `{ headerContent, id, meta: {}, sections }`.
+- Fix: extract `buildNewEntry(headerContent, prefix, existingIds, sections)` factory.
+
+#### 6) `UNUSED_STUB` dead error kind in `CommandError` union
+- File: `commanders/textfresser/errors.ts`
+- `CommandErrorKind.UNUSED_STUB` is never produced or matched. Remove it.
+
+#### 7) Zod v4 imports in 3 files violate project `zod/v3` convention
+- Files: `commanders/textfresser/errors.ts`, `commands/types.ts`, `domain/dict-entry-id/tags.ts`
+- All use `import { z } from "zod"` (v4) but only v3-compatible features. Risk: schemas passed to v3-expecting code can trigger `_zod.run is not a function`.
+- Fix: migrate to `"zod/v3"`.
+- Cross-ref: related to book-of-work 2.2.
+
+#### 8) `generateNewEntrySections` — positional index coupling in `Promise.allSettled` unwrap
+- File: `commands/generate/steps/generate-new-entry-sections.ts`
+- 6 LLM calls via `Promise.allSettled`, unwrapped by hard-coded indices (`settled[0]`..`settled[5]`). Adding/removing/reordering a prompt silently breaks the mapping.
+- Fix: use named object → `Promise.allSettled([...])` with named destructuring.
+- Cross-ref: complements book-of-work 2.1.
+
+### P2 (testing gaps)
+
+#### 9) `foldScopedActionsToSingleWritePerTarget` has no direct unit test
+- File: `commands/generate/steps/propagate-core.ts`
+- Critical contract: collapse multiple `UpsertMdFile` + `ProcessMdFile` pairs per target into a single composed transform. Only tested indirectly.
+- Needed: multiple transforms composed in order, `UpsertMdFile` seed → `ProcessMdFile` chaining, dedup, failure path.
+
+#### 10) `check-attestation`, `serialize-entry`, `move-to-worter` steps have no unit tests
+- Files: `steps/check-attestation.ts`, `steps/serialize-entry.ts`, `steps/move-to-worter.ts`
+- `checkAttestation` is the entry gate (two branches untested). `serializeEntry` has the unguarded cast (#2). `moveToWorter` has untested "already at destination" skip.
+
+### P3 (code hygiene)
+
+#### 11) `note-adapter.ts` decomposition targets (993 lines)
+- File: `domain/propagation/note-adapter.ts`
+- Suggested split: `wikilink-dto.ts`, `section-parsers.ts`, `section-serializers.ts`, thin orchestrator.
+- Cross-ref: provides specific decomposition plan for book-of-work 2.1.
+
+#### 12) Module-level mutable `warningCountBySampleKey` state
+- File: `domain/propagation/note-adapter.ts`
+- Sampling rate-limiter accumulates across Obsidian process lifetime. 2000-key cap clears entire map. Makes tests order-dependent.
+- Fix: extract into factory function; production keeps singleton, tests get fresh state.
+
+#### 13) Anonymous 120-line inline transform closure in `propagate-morphology-relations.ts`
+- File: `steps/propagate-morphology-relations.ts` (Equation-kind branch)
+- Untestable in isolation. Extract to named `buildEquationTransform(params)` top-level function.
+
+#### 14) `MORPHOLOGY_STEM_MATCH_MIN_LENGTH = 4` needs calibration
+- File: `steps/propagate-morphemes.ts`
+- Magic constant with stale `TODO calibrate` comment. Add 5-10 real German morpheme test cases to lock in boundary behaviour.
+
+#### 15) `CommandStateWithLemma` nested Omit type hurts hover clarity
+- File: `commands/types.ts`
+- Deep `Omit + intersection` expands at hover. Extract named `TextfresserStateWithLemma` interface.
