**Notes**:

* Confirmed Phase 35 marks Sessions 06 and 07 complete and validated before starting the world/type ownership split.
* Confirmed both prior session directories contain implementation, review, security, and validation artifacts.

**Files Changed**:

* `.spec_system/specs/phase35-session08-world-types-and-fixture-cleanup/implementation-notes.md` - Created the implementation evidence ledger and recorded dependency verification.
* `.spec_system/specs/phase35-session08-world-types-and-fixture-cleanup/tasks.md` - Marked T001 complete after evidence was recorded.

**Verification**:

* Command/check: `if [ -d ".spec_system/scripts" ]; then bash .spec_system/scripts/analyze-project.sh --json; else bash /home/aiwithapex/.codex/plugins/cache/apex-spec-system/apex-spec/2.1.3-codex/scripts/analyze-project.sh --json; fi`
  * Result: PASS - analyzer reported current session `phase35-session08-world-types-and-fixture-cleanup`, completed\_sessions includes `phase35-session06-simulation-ownership-refactor` and `phase35-session07-renderer-and-react-bridge-refactor`, and Session 08 is the earliest incomplete Phase 35 session.
  * Evidence: Analyzer output showed Phase 35 in progress with Sessions 01-07 completed and candidate Session 08 incomplete.
* Command/check: `rg -n "Session 06|Session 07|Tasks Complete|25/25|20/20|Result: PASS" .spec_system/PRD/phase_35/PRD_phase_35.md .spec_system/specs/phase35-session06-simulation-ownership-refactor/validation.md .spec_system/specs/phase35-session07-renderer-and-react-bridge-refactor/validation.md`
  * Result: PASS - Phase 35 PRD lists Session 06 and Session 07 complete on 2026-06-26, Session 06 validation reports 20/20 tasks complete, and Session 07 validation reports PASS with 25/25 tasks complete.

### Task T002 - Inventory current world and type imports

**Started**: 2026-06-27 00:11 **Completed**: 2026-06-27 00:12 **Duration**: 1 minute

**Notes**:

* Inventoried all current exports from `runtime/world.ts` and `runtime/types.ts`.
* Confirmed `runtime/world.ts` is imported by core runtime modules (`entities`, `snapshot`, `run-factory`, `simulation`, `fov`, `floor-arc`, `inspect`, and `simulation-fixtures`) plus runtime tests.
* Confirmed `runtime/types.ts` is imported broadly inside runtime modules and tests, so the split needs compatibility re-exports during this session.
* Confirmed non-runtime AI Rogue tests import `../runtime/world`, but no product route source imports fixture-only world helpers directly.

**Files Changed**:

* `.spec_system/specs/phase35-session08-world-types-and-fixture-cleanup/implementation-notes.md` - Recorded import/export inventory evidence.
* `.spec_system/specs/phase35-session08-world-types-and-fixture-cleanup/tasks.md` - Marked T002 complete after evidence was recorded.

**Verification**:

* Command/check: `rg -n "^export (type |interface |const |function )" src/extensions/ai-rogue/runtime/world.ts src/extensions/ai-rogue/runtime/types.ts`
  * Result: PASS - export inventory listed 17 world exports and all broad type exports that need owner modules or compatibility re-exports.
  * Evidence: `world.ts` exports generation, fixture rows, tile, geometry, and frame names; `types.ts` exports runtime, world/entity, simulation, progression, and save/controller domains.
* Command/check: `rg -n "from \"\\./world\"|from \"\\.\\./world\"|from './world'|from '../world'" src/extensions/ai-rogue/runtime -g '*.ts' -g '*.tsx'`
  * Result: PASS - current runtime world imports were identified for core modules and tests.
  * Evidence: Import list includes `run-factory`, `simulation`, `fov`, `snapshot`, `entities`, `floor-arc`, `inspect`, `simulation-fixtures`, and runtime tests.
* Command/check: `rg -n "from \"\\./types\"|from \"\\.\\./types\"|from './types'|from '../types'" src/extensions/ai-rogue/runtime -g '*.ts' -g '*.tsx'`
  * Result: PASS - current runtime type imports were identified across runtime modules and tests.
  * Evidence: Import list includes renderer, mount, input, effects, render-model, simulation, run-factory, tests, and support modules.
* Command/check: `rg -n "runtime/(world|types)|runtime\\/world|runtime\\/types|from \"../runtime/(world|types)\"|from '../runtime/(world|types)'" src/extensions/ai-rogue -g '*.ts' -g '*.tsx'`
  * Result: PASS - only `save-schema.ts` has a comment mentioning `runtime/types.ts`, and package tests import `../runtime/world`; no product route source imports fixture-only world internals.
  * Evidence: Hits were `src/extensions/ai-rogue/save-schema.ts` and AI Rogue package tests.
* UI product-surface check: N/A - Source inventory task only.
* UI craft check: N/A - Source inventory task only.

* `src/extensions/ai-rogue/runtime/simulation-fixtures.ts` - Routed fixture helpers through explicit fixture and generator modules.
* `.spec_system/specs/phase35-session08-world-types-and-fixture-cleanup/implementation-notes.md` - Recorded T014 evidence.
* `.spec_system/specs/phase35-session08-world-types-and-fixture-cleanup/tasks.md` - Marked T014 complete after evidence was recorded.

**Verification**:

* Command/check: `bun run typecheck`
  * Result: PASS - Fixture routing compiled successfully.
  * Evidence: `tsc --noEmit` completed with exit code 0.
* Command/check: `bun run test -- src/extensions/ai-rogue/runtime/__tests__/runtime-boundary.test.ts`
  * Result: PASS - 1 test file and 6 tests passed.
  * Evidence: Public runtime barrel, product route import boundary, and fixture import isolation remained valid.
* UI product-surface check: N/A - Fixture import-boundary refactor only.
* UI craft check: N/A - Fixture import-boundary refactor only.

### Task T015 - Refresh boundary and runtime characterization tests

**Started**: 2026-06-27 00:29 **Completed**: 2026-06-27 00:30 **Duration**: 1 minute

**Notes**:

* `src/extensions/ai-rogue/runtime/__tests__/compile.test.ts` - Imports fixture parser and run-state type from focused owners.
* `src/extensions/ai-rogue/runtime/__tests__/prefabs.test.ts` - Imports generated-world API and world type from focused owners.
* `src/extensions/ai-rogue/runtime/__tests__/vault.test.ts` - Imports fixture/generator APIs and run-state type from focused owners.
* `src/extensions/ai-rogue/runtime/__tests__/terminals.test.ts` - Imports fixture/generator APIs and run-state type from focused owners.

* `.spec_system/specs/phase35-session08-world-types-and-fixture-cleanup/tasks.md` - Marked T015 complete after evidence was recorded.

**Verification**:

* Command/check: `bun run typecheck`
  * Result: PASS - Refreshed test imports compiled successfully.
  * Evidence: `tsc --noEmit` completed with exit code 0.
* Command/check: `bun run test -- src/extensions/ai-rogue/runtime/__tests__/world.test.ts src/extensions/ai-rogue/runtime/__tests__/prefabs.test.ts src/extensions/ai-rogue/runtime/__tests__/vault.test.ts src/extensions/ai-rogue/runtime/__tests__/terminals.test.ts src/extensions/ai-rogue/runtime/__tests__/runtime-boundary.test.ts src/extensions/ai-rogue/runtime/__tests__/compile.test.ts`
  * Result: PASS - 6 test files and 35 tests passed.
  * Evidence: Runtime boundary, compile, world, prefab, vault, terminal, deterministic generation, and fixture parser characterization tests passed.
* UI product-surface check: N/A - Test refresh only.
* UI craft check: N/A - Test refresh only.

**BQC Fixes**:

* Trust boundary enforcement: Added direct tests for unsupported fixture cells and duplicate start/exit markers (`src/extensions/ai-rogue/runtime/__tests__/world.test.ts`).

# 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/phase35-session08-world-types-and-fixture-cleanup/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.
