### Task T011 - Prefer level-spec authoring path assertions

**Started**: 2026-06-30 20:09 **Completed**: 2026-06-30 20:11 **Duration**: 2 minutes

**Notes**:

* Updated the registry test to assert every `AI_ROGUE_LEVEL_SPECS` depth resolves through `levelSpecForDepth()`.
* Kept `authoredLevelSpecForDepth()` asserted as the legacy nullable wrapper during migration.
* Existing out-of-range lookup coverage remains in place for `levelSpecForDepth()`.

**Files Changed**:

* `src/extensions/ai-rogue/runtime/content/__tests__/levels.test.ts` - added direct authored registry lookup assertions.
* `.spec_system/specs/phase39-session03-registry-validation-and-save-parity/implementation-notes.md` - recorded T011 evidence.
* `.spec_system/specs/phase39-session03-registry-validation-and-save-parity/tasks.md` - marked T011 complete and updated progress summary.

* UI product-surface check: N/A - test-only task.
* UI craft check: N/A - no user-facing UI changed.

***

### Task T010 - Cover every invalid reference named by the session

**Started**: 2026-06-30 20:09 **Completed**: 2026-06-30 20:11 **Duration**: 2 minutes

**Notes**:

* Expanded the registry test table to cover invalid theme, enemy, terminal, protocol, prefab, pickup, objective, music, ambience, boss, and finale ownership references.
* Each case asserts the expected issue code and JSON path.
* Each case verifies invalid source values are not echoed in serialized validation issue output.

**Files Changed**:

* `src/extensions/ai-rogue/runtime/content/__tests__/levels.test.ts` - expanded malformed-reference test coverage for all session-named reference classes.
* `.spec_system/specs/phase39-session03-registry-validation-and-save-parity/implementation-notes.md` - recorded T010 evidence.
* `.spec_system/specs/phase39-session03-registry-validation-and-save-parity/tasks.md` - marked T010 complete and updated progress summary.

**Started**: 2026-06-30 20:08 **Completed**: 2026-06-30 20:11 **Duration**: 3 minutes

**Notes**:

* Added objective kind reference validation separate from generic level shape checks.
* Restricted finale boss references to the explicit boss catalog entry.
* Added finale ownership checks for non-final boss ownership, non-final objective-clear requirements, and final objective-clear requirements that point at no concrete objective.
* Kept issue output sanitized with stable code/path metadata.

**Files Changed**:

* `src/extensions/ai-rogue/runtime/content/validate.ts` - added objective, boss, and finale ownership validation.

  * Evidence: 1 test file passed; 6 tests passed.
* Command/check: targeted inspection of `src/extensions/ai-rogue/runtime/content/validate.ts`
  * Result: PASS - validator now uses `invalid-pickup-reference`, `invalid-objective-reference`, `invalid-boss-reference`, and `invalid-finale-reference` for the relevant ownership failures.
  * Evidence: `validateLocalReferences()` validates pickup and objective references; `validateFinaleOwnership()` validates finale ownership rules.
* UI product-surface check: N/A - no user-facing UI changed.
* UI craft check: N/A - no user-facing UI changed.

**BQC Fixes**:

* Trust boundary enforcement: malformed authored level references crossing into runtime generation are rejected before use (`src/extensions/ai-rogue/runtime/content/validate.ts`).
* Error information boundaries: invalid objective, boss, and finale inputs are not echoed in validation issues (`src/extensions/ai-rogue/runtime/content/__tests__/levels.test.ts`).

* UI product-surface check: N/A - no user-facing UI changed.
* UI craft check: N/A - no user-facing UI changed.

**BQC Fixes**:

* Contract alignment: nested placement and enemy references now have exact regression coverage for their declared validation paths (`src/extensions/ai-rogue/runtime/content/__tests__/levels.test.ts`).

***

### Task T007 - Harden generation reference validation

**Started**: 2026-06-30 20:09 **Completed**: 2026-06-30 20:11 **Duration**: 2 minutes

**Notes**:

* Verified generation reference validation for theme, baseline protocol, music track, and ambience IDs through exact issue-code and path assertions.
* Kept validation output sanitized by asserting an unsafe invalid source value does not appear in serialized issue objects.
* Preserved the existing theme-to-ambience ownership check so mismatched ambience IDs fail even when the ambience ID exists.

**Files Changed**:

* `src/extensions/ai-rogue/runtime/content/__tests__/levels.test.ts` - added exact malformed generation reference cases.
* `.spec_system/specs/phase39-session03-registry-validation-and-save-parity/implementation-notes.md` - recorded T007 evidence.
* `.spec_system/specs/phase39-session03-registry-validation-and-save-parity/tasks.md` - marked T007 complete and updated progress summary.

  * Result: PASS - generation reference issue expectations passed.
  * Evidence: 1 test file passed; 6 tests passed.
* Command/check: targeted inspection of `src/extensions/ai-rogue/runtime/content/validate.ts`
  * Result: PASS - generation validation emits `invalid-theme-reference`, `invalid-protocol-reference`, `invalid-music-reference`, and `invalid-ambience-reference` with path-only messages.
  * Evidence: `validateLocalReferences()` validates `generation.themeId`, `generation.baselineProtocolId`, `generation.musicTrackId`, and `generation.ambienceId`.
* UI product-surface check: N/A - no user-facing UI changed.
* UI craft check: N/A - no user-facing UI changed.

**BQC Fixes**:

* Error information boundaries: malformed generation values are represented by stable code/path metadata and are not echoed in issue output (`src/extensions/ai-rogue/runtime/content/__tests__/levels.test.ts`).

***

### Task T006 - Extend malformed-reference test helpers

**Started**: 2026-06-30 20:09 **Completed**: 2026-06-30 20:11 **Duration**: 2 minutes

**Notes**:

* Added focused helper functions for generation, placement, guarantee, objective, and finale nested spec mutations.
* Added `expectReferenceIssue()` to assert exact issue code and path while confirming unsafe invalid source values are not echoed.
* Preserved the existing clone helpers so test cases mutate deep copies rather than shared registry constants.

**Files Changed**:

* `src/extensions/ai-rogue/runtime/content/__tests__/levels.test.ts` - added nested mutation helpers and sanitized issue assertion helper.
* `.spec_system/specs/phase39-session03-registry-validation-and-save-parity/implementation-notes.md` - recorded T006 evidence.
* `.spec_system/specs/phase39-session03-registry-validation-and-save-parity/tasks.md` - marked T006 complete and updated progress summary.

  * Result: PASS - helper-backed malformed-reference coverage passed.
  * Evidence: 1 test file passed; 6 tests passed.
* Command/check: targeted inspection of `src/extensions/ai-rogue/runtime/content/__tests__/levels.test.ts`
  * Result: PASS - helper coverage spans generation, placement, enemy table, guarantees, objective, boss, and finale mutations.
  * Evidence: helpers include `withGeneration`, `withPlacement`, `withGuarantees`, `withObjective`, `withFinale`, and `expectReferenceIssue`.
* UI product-surface check: N/A - test-only task.
* UI craft check: N/A - no user-facing UI changed.

**Started**: 2026-06-30 20:08 **Completed**: 2026-06-30 20:11 **Duration**: 3 minutes

**Notes**:

* Added explicit validation codes for objective, boss, and finale ownership drift.
* Routed invalid floor objective kinds to `invalid-objective-reference`.
* Routed non-boss or unknown finale boss references to `invalid-boss-reference`.
* Added finale ownership checks so non-final levels cannot own finale bosses or objective-clear requirements.

**Files Changed**:

* `src/extensions/ai-rogue/runtime/content/types.ts` - added `invalid-objective-reference`, `invalid-boss-reference`, and `invalid-finale-reference` to the validation code union.
* `src/extensions/ai-rogue/runtime/content/validate.ts` - emitted the new issue codes from objective, boss, and finale ownership validation paths.

  * Result: PASS - registry validation suite passed with the new explicit codes.
  * Evidence: 1 test file passed; 6 tests passed.
* Command/check: targeted inspection of `src/extensions/ai-rogue/runtime/content/types.ts`
  * Result: PASS - issue-code union includes the new objective, boss, and finale ownership codes.
  * Evidence: `AiRogueLevelValidationCode` contains `invalid-objective-reference`, `invalid-boss-reference`, and `invalid-finale-reference`.
* UI product-surface check: N/A - no user-facing UI changed.
* UI craft check: N/A - no user-facing UI changed.

**BQC Fixes**:

* Contract alignment: objective and finale ownership failures now have dedicated issue codes instead of being folded into generic shape or enemy-reference errors (`src/extensions/ai-rogue/runtime/content/types.ts`, `src/extensions/ai-rogue/runtime/content/validate.ts`).

### Task T005 - Add save-schema parity tests

**Started**: 2026-06-30 20:07 **Completed**: 2026-06-30 20:08 **Duration**: 1 minute

**Notes**:

* Added parity cases for enemy kinds, sector themes, protocol IDs, and terminal IDs.
* Runtime active IDs are compared against parser-owned persisted ID arrays with deterministic sorting.
* Save-only IDs are required to appear in explicit compatibility arrays, and accepted ID arrays are checked for duplicates.
* BQC contract-alignment check: adding a runtime active ID without save-schema coverage now fails the parity suite.

**Files Changed**:

* `src/extensions/ai-rogue/__tests__/save-schema-parity.test.ts` - created runtime/save-schema persisted ID parity coverage.
* `.spec_system/specs/phase39-session03-registry-validation-and-save-parity/implementation-notes.md` - recorded T005 evidence.

  * Evidence: 2 test files passed; 25 tests passed.
* Command/check: targeted inspection of `src/extensions/ai-rogue/__tests__/save-schema-parity.test.ts`
  * Result: PASS - runtime catalogs are imported only in tests, not in `save-schema.ts`.
  * Evidence: test imports runtime `entities`, `protocols`, `terminals`, and `themes` plus exported save-schema arrays.
* UI product-surface check: N/A - test-only task.
* UI craft check: N/A - no user-facing UI changed.

***

### Task T003 - Export persisted and compatibility save-schema ID arrays

**Started**: 2026-06-30 20:06 **Completed**: 2026-06-30 20:08 **Duration**: 2 minutes

**Notes**:

* Factored protocol, enemy, terminal, and sector theme persisted IDs into exported parser-owned readonly arrays.
* Added explicit empty compatibility arrays for future retired IDs without importing runtime catalogs into the save schema.
* Built the existing zod enums from active plus compatibility arrays, preserving schema version `1` and current parser behavior.
* BQC contract-alignment check: the parser continues to own its accepted persisted IDs and exposes them for tests without runtime coupling.

**Files Changed**:

* `src/extensions/ai-rogue/save-schema.ts` - exported persisted and compatibility ID arrays and reused them for protocol, enemy, terminal, and theme zod enums.
* `.spec_system/specs/phase39-session03-registry-validation-and-save-parity/implementation-notes.md` - recorded T003 evidence.

  * Result: PASS - exported arrays preserve existing parser behavior and support parity checks.
  * Evidence: 2 test files passed; 25 tests passed.
* Command/check: targeted inspection of `src/extensions/ai-rogue/save-schema.ts`
  * Result: PASS - no runtime catalog imports were added to the parser module.
  * Evidence: parser imports remain `zod`, economy/input/progression schemas, and no `runtime/*` modules.
* UI product-surface check: N/A - no user-facing UI changed.
* UI craft check: N/A - no user-facing UI changed.

**Notes**:

* Verified the current session was `phase39-session03-registry-validation-and-save-parity` from the spec analysis output.
* Reviewed the Session 03 PRD stub, generated session spec, generated task checklist, current registry validator, current save-schema enum shape, and focused existing test files.
* Confirmed Session 01 and Session 02 are listed as completed in deterministic state output.

**Files Changed**:

* `.spec_system/specs/phase39-session03-registry-validation-and-save-parity/implementation-notes.md` - created implementation progress log.
* `.spec_system/specs/phase39-session03-registry-validation-and-save-parity/tasks.md` - marked T001 complete and added progress summary.

**Verification**:

* Command/check: `bash .spec_system/scripts/analyze-project.sh --json`
  * Result: PASS - current session resolved and previous Phase 39 sessions were reported completed.
  * Evidence: `current_session` was `phase39-session03-registry-validation-and-save-parity`; completed sessions included `phase39-session01-baseline-and-registry-skeleton` and `phase39-session02-depth-resolver-migration`.
* Command/check: `bash .spec_system/scripts/check-prereqs.sh --json --env`
  * Result: PASS - environment checks passed.
  * Evidence: `.spec_system`, `jq`, and `git` checks passed.
* Command/check: `bash .spec_system/scripts/check-prereqs.sh --json --tools "bun,bunx"`
  * Result: PASS - Bun and bunx were available at the repo-pinned baseline.
  * Evidence: tool check reported `bun` and `bunx` version `1.3.14`.
* Command/check: `bunx vitest run src/extensions/ai-rogue/runtime/content/__tests__/levels.test.ts src/extensions/ai-rogue/__tests__/save-schema.test.ts src/extensions/ai-rogue/runtime/__tests__/runtime-boundary.test.ts`

### Task T002 - Confirm active runtime ID sources

**Started**: 2026-06-30 20:05 **Completed**: 2026-06-30 20:06 **Duration**: 1 minute

**Notes**:

* Confirmed runtime catalog sources for enemies, themes, protocols, terminals, prefabs, music, ambience, pickups, objectives, and finale ownership.
* Verified the existing content validator imports only runtime catalog modules and no route, renderer, bridge, generated-data, public-demo, or PixiJS modules.
* BQC contract-alignment focus: ID ownership is currently split between runtime catalogs and save-schema enums, so later tasks will expose parser-owned arrays and test parity without importing runtime catalogs into the parser.

**Files Changed**:

* `.spec_system/specs/phase39-session03-registry-validation-and-save-parity/implementation-notes.md` - recorded active ID source evidence.
* `.spec_system/specs/phase39-session03-registry-validation-and-save-parity/tasks.md` - marked T002 complete and updated progress summary.

**Verification**:

* Command/check: `rg -n "AI_ROGUE_ENEMY_TEMPLATES|AI_ROGUE_SECTOR_THEMES|AI_ROGUE_PROTOCOLS|AI_ROGUE_TERMINALS|AI_ROGUE_PREFABS|AI_ROGUE_THEME_AMBIENCE_FILE_BASENAMES|AiRogueMusicId|AiRoguePickupKind|AiRogueFloorObjective|bossKind|finale" src/extensions/ai-rogue/runtime src/extensions/ai-rogue/save-schema.ts`
  * Result: PASS - active source declarations were located in runtime catalog/type modules and current save-schema persisted enum sites.
  * Evidence: enemy templates are in `runtime/entities.ts`; themes in `runtime/themes.ts`; protocols in `runtime/protocols.ts`; terminals in `runtime/terminals.ts`; prefabs in `runtime/prefabs.ts`; music and ambience in `runtime/audio.ts`; pickups and floor objectives in `runtime/types-entities.ts`; finale ownership in `runtime/content/types.ts` and `runtime/content/validate.ts`.
* Command/check: targeted inspection of `src/extensions/ai-rogue/runtime/content/validate.ts`
  * Result: PASS - validator imports runtime catalog modules only.
  * Evidence: imports are limited to `entities`, `prefabs`, `protocols`, `themes`, `terminals`, and local `content/levels` plus local types.
* UI product-surface check: N/A - task only inspected runtime and parser ownership.
* UI craft check: N/A - no user-facing UI changed.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://ai-os-and-trend-finder.gitbook.io/ai-os-and-trend-finder-docs/.spec_system/archive/sessions/phase39-session03-registry-validation-and-save-parity/implementation-notes.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
