## Task Log

### Task T020 - Run final formatting, encoding, and handoff checks

**Started**: 2026-06-24 00:47 **Completed**: 2026-06-24 00:50 **Duration**: 3 minutes

**Notes**:

* Ran targeted Prettier formatting and checks for all session-touched files.
* Reran focused public-demo, registry, and setup-config suites after formatting.
* Reran full typecheck after the final demo SPA output-path change.
* Repaired one newly untracked, out-of-scope AI Rogue test mock that widened `ok: false` to `boolean` and blocked the repo-wide typecheck gate.
* `git diff --check` passed.
* Session-touched files passed ASCII/LF scanning.
* A broad dirty-worktree ASCII scan found pre-existing non-ASCII punctuation in the AI Rogue Rotten Soup gameplay-depth note; that unrelated user/worktree file was not modified for this session. The durable content now lives in `docs/extensions/ai-rogue/gameplay-depth.md`.

**Files Changed**:

* `.spec_system/specs/phase31-session01-demo-mode-foundation/tasks.md` - completed final task and checklist handoff.
* `.spec_system/specs/phase31-session01-demo-mode-foundation/implementation-notes.md` - recorded final verification evidence and handoff.
* `src/extensions/ai-rogue/__tests__/runtime-canvas.test.tsx` - narrowed a mock failure result to `ok: false as const` so current repo typecheck passes.

**Verification**:

* Command/check: `bunx prettier --check src/lib/public-demo.ts src/lib/__tests__/public-demo.test.ts src/vite-env.d.ts src/extensions/registry.ts src/lib/setup-config.ts src/lib/__tests__/extension-registry.test.ts src/lib/__tests__/setup-config-extensions.test.ts src/start.ts vite.config.ts src/extensions/ai-rogue/__tests__/runtime-canvas.test.tsx .spec_system/specs/phase31-session01-demo-mode-foundation/implementation-notes.md .spec_system/specs/phase31-session01-demo-mode-foundation/tasks.md`
  * Result: PASS - targeted formatting check passed.
  * Evidence: `All matched files use Prettier code style!`
* Command/check: `bun run test -- src/lib/__tests__/public-demo.test.ts src/lib/__tests__/extension-registry.test.ts src/lib/__tests__/setup-config-extensions.test.ts`
  * Result: PASS - focused tests passed after formatting.
  * Evidence: 3 test files passed; 68 tests passed.
* Command/check: `bun run typecheck`
  * Result: PASS - repo-wide TypeScript check passed after the out-of-scope mock type repair.
  * Evidence: `tsc --noEmit` exited 0.
* Command/check: `git diff --check`
  * Result: PASS - no whitespace errors in the diff.
  * Evidence: Command exited 0.
* Command/check: targeted ASCII/LF scan over session-touched source, test, config, and spec files.
  * Result: PASS - session files are ASCII-only with LF endings.
  * Evidence: `SESSION_ASCII_LF_SCAN_DONE checked=12`.
* UI product-surface check: N/A - no user-facing route or visual component changed.
* UI craft check: N/A - no UI files changed.

**BQC Fixes**:

* Contract alignment: final checks confirmed public-demo env parsing, extension visibility, setup config reporting, and build mode branching remain aligned across tests and build outputs.

### Task T019 - Run demo-pages build

**Started**: 2026-06-24 00:45 **Completed**: 2026-06-24 00:47 **Duration**: 2 minutes

**Notes**:

* Ran the demo-pages build with public-demo mode and all extensions enabled.
* Initial SPA shell output used TanStack Start's default `_shell.html`; adjusted the SPA prerender output path to `/index` so the client output contains `index.html`.
* Verified the demo build does not emit Cloudflare Worker deployment artifacts such as `wrangler.json` or `_worker.js`.
* TanStack still emits `demo-website/dist/server/server.js` for prerender/build support; Session 05 should point Pages at `demo-website/dist/client` or otherwise package only the static client output.

**Files Changed**:

* `vite.config.ts` - set demo SPA prerender output path to `/index`.
* `demo-website/dist/` - generated demo-pages build artifacts.
* `.spec_system/specs/phase31-session01-demo-mode-foundation/implementation-notes.md` - recorded demo build evidence.

**Verification**:

* Command/check: `VITE_AI_OS_PUBLIC_DEMO=1 VITE_CLAUDE_OS_ENABLED_EXTENSIONS=all bunx vite build --mode demo-pages`
  * Result: PASS - demo-pages build completed.
  * Evidence: Vite built client and server environments for `demo-pages`; prerender completed for `/`.
* Command/check: `test -f demo-website/dist/client/index.html`
  * Result: PASS - static HTML entry exists.
  * Evidence: `static_html=pass`; `demo-website/dist/client/index.html` is present.
* Command/check: `find demo-website/dist -name 'wrangler.json' -o -name '_worker.js'`
  * Result: PASS - Cloudflare Worker deployment artifacts are absent.
  * Evidence: `worker_artifacts=absent`.
* UI product-surface check: N/A - build verification only.
* UI craft check: N/A - no UI files changed.

**BQC Fixes**:

* Contract alignment: demo SPA output now emits an `index.html` entry compatible with a Pages SPA fallback (`vite.config.ts`).

***

### Task T018 - Run normal Worker build

**Started**: 2026-06-24 00:44 **Completed**: 2026-06-24 00:45 **Duration**: 1 minute

**Notes**:

* Ran the normal production build path after adding the demo-pages branch.
* Normal build still emits the Worker/client output shape.

**Files Changed**:

* `dist/` - regenerated normal build artifacts.
* `.spec_system/specs/phase31-session01-demo-mode-foundation/implementation-notes.md` - recorded normal build evidence.

**Verification**:

* Command/check: `bun run build`
  * Result: PASS - normal production build completed.
  * Evidence: Vite built client and SSR environments and emitted `dist/server/wrangler.json`.
* Command/check: `test -d dist/client && test -f dist/server/wrangler.json`
  * Result: PASS - normal build output shape exists.
  * Evidence: `normal_build_shape=pass`; `dist/client`, `dist/server/index.js`, and `dist/server/wrangler.json` are present.
* UI product-surface check: N/A - build verification only.
* UI craft check: N/A - no UI files changed.

***

### Task T017 - Run TypeScript check

**Started**: 2026-06-24 00:42 **Completed**: 2026-06-24 00:44 **Duration**: 2 minutes

**Notes**:

* Ran the project TypeScript check after helper, registry, setup config, Start, and Vite config changes.
* No import, env typing, or Vite config type repairs were needed.

**Files Changed**:

* `.spec_system/specs/phase31-session01-demo-mode-foundation/implementation-notes.md` - recorded typecheck evidence.

**Verification**:

* Command/check: `bun run typecheck`
  * Result: PASS - TypeScript passed.
  * Evidence: `tsc --noEmit` exited 0.
* UI product-surface check: N/A - no user-facing route or visual component changed.
* UI craft check: N/A - no UI files changed.

***

### Task T016 - Run focused public-demo and extension tests

**Started**: 2026-06-24 00:41 **Completed**: 2026-06-24 00:42 **Duration**: 1 minute

**Notes**:

* Ran the public-demo helper, extension registry, and setup-config extension suites together after all implementation changes.
* No env-state leakage or behavior regressions were found.

**Files Changed**:

* `.spec_system/specs/phase31-session01-demo-mode-foundation/implementation-notes.md` - recorded focused test evidence.

**Verification**:

* Command/check: `bun run test -- src/lib/__tests__/public-demo.test.ts src/lib/__tests__/extension-registry.test.ts src/lib/__tests__/setup-config-extensions.test.ts`
  * Result: PASS - focused suites passed.
  * Evidence: 3 test files passed; 68 tests passed.
* UI product-surface check: N/A - no user-facing route or visual component changed.
* UI craft check: N/A - no UI files changed.

***

### Task T015 - Verify prohibited behavior was not introduced

**Started**: 2026-06-24 00:40 **Completed**: 2026-06-24 00:41 **Duration**: 1 minute

**Notes**:

* Verified added code is limited to env parsing, extension visibility selection, Start SPA/SSR config, and output path selection.
* No hosted collection, local bridge, setup write, scheduler, admin, upload, chat, source mutation, dynamic loading, analytics, or Pages Functions behavior was introduced.
* No new `isExample`, LiveData, or `/__live-data` coupling was added.

**Files Changed**:

* `.spec_system/specs/phase31-session01-demo-mode-foundation/implementation-notes.md` - recorded prohibited-behavior verification.

**Verification**:

* Command/check: `git diff --unified=0 -- src/lib/public-demo.ts src/extensions/registry.ts src/lib/setup-config.ts vite.config.ts src/start.ts | rg -n '^\\+.*(fetch\\(|/__|localStorage|indexedDB|analytics|eval|new Function|Function\\(|upload|chat|scheduler|admin|mutation|collect|bridge|dynamic import|Pages Functions)' || true`
  * Result: PASS - no prohibited added-code matches found.
  * Evidence: Command produced no matches.
* Command/check: `rg -n "isExample|LiveData|__live-data" src/lib/public-demo.ts src/extensions/registry.ts src/lib/setup-config.ts src/start.ts || true`
  * Result: PASS - no new fallback-data coupling found in touched helper/config files.
  * Evidence: Command produced no matches.
* UI product-surface check: N/A - no user-facing route or visual component changed.
* UI craft check: N/A - no UI files changed.

***

### Task T014 - Separate demo-pages output from Worker deployment path

**Started**: 2026-06-24 00:39 **Completed**: 2026-06-24 00:40 **Duration**: 1 minute

**Notes**:

* Demo-pages mode now writes to `demo-website/dist` instead of the normal Worker `dist` path.
* Normal builds keep the default `dist` output for `dist/client` and `dist/server`.
* Session 05 follow-up remains: add Pages `_headers`, `_redirects`, demo scripts, preview scripts, and deployment documentation around `demo-website/`.

**Files Changed**:

* `vite.config.ts` - added demo-only `build.outDir` and `emptyOutDir`.
* `.spec_system/specs/phase31-session01-demo-mode-foundation/implementation-notes.md` - recorded Session 05 output-scaffold follow-up.

**Verification**:

* Command/check: `bun run typecheck`
  * Result: PASS - Vite build config typechecks with demo output branch.
  * Evidence: `tsc --noEmit` exited 0.
* Command/check: `rg -n "demo-website/dist|outDir|emptyOutDir" vite.config.ts`
  * Result: PASS - output branch inspected.
  * Evidence: `build.outDir` is set only when `isDemoPagesMode` is true.
* UI product-surface check: N/A - build configuration only.
* UI craft check: N/A - no UI files changed.

***

### Task T013 - Add demo-only defaultSsr support

**Started**: 2026-06-24 00:37 **Completed**: 2026-06-24 00:39 **Duration**: 2 minutes

**Notes**:

* Added demo-only `defaultSsr: false` through the installed TanStack Start `createStart` option.
* Kept the existing error middleware intact in `requestMiddleware`.
* Used the shared public-demo parser instead of reading `isExample` or duplicating flag parsing.

**Files Changed**:

* `src/start.ts` - added demo-only `defaultSsr: false` while preserving error middleware.

**Verification**:

* Command/check: `bun run typecheck`
  * Result: PASS - Start option and middleware types compile.
  * Evidence: `tsc --noEmit` exited 0.
* Command/check: `sed -n '1,60p' src/start.ts`
  * Result: PASS - start config inspected.
  * Evidence: `defaultSsr: false` is spread only when `isPublicDemoEnv(import.meta.env)` is true, and `requestMiddleware` still includes `errorMiddleware`.
* UI product-surface check: N/A - app start configuration only.
* UI craft check: N/A - no UI files changed.

**BQC Fixes**:

* Failure path completeness: existing SSR error middleware remains configured for non-demo SSR paths while demo mode changes only the default SSR option (`src/start.ts`).

***

### Task T012 - Configure TanStack Start SPA output for demo-pages

**Started**: 2026-06-24 00:35 **Completed**: 2026-06-24 00:37 **Duration**: 2 minutes

**Notes**:

* Added `spa: { enabled: true, maskPath: "/" }` only when `isDemoPagesMode` is true.
* Kept import protection and route test ignore configuration common across normal and demo builds.
* Kept `server: { entry: "server" }` only for non-demo builds, preserving the Worker server wrapper outside demo mode.

**Files Changed**:

* `vite.config.ts` - added TanStack Start SPA option branch for demo-pages mode.

**Verification**:

* Command/check: `bun run typecheck`
  * Result: PASS - installed TanStack Start option shape accepts the branch.
  * Evidence: `tsc --noEmit` exited 0.
* Command/check: `sed -n '440,465p' vite.config.ts`
  * Result: PASS - TanStack Start options inspected.
  * Evidence: demo mode sets `spa.enabled` and normal mode retains `server.entry = "server"`.
* UI product-surface check: N/A - build configuration only.
* UI craft check: N/A - no UI files changed.

**BQC Fixes**:

* Contract alignment: demo build no longer points TanStack Start at the Worker wrapper while normal builds still do (`vite.config.ts`, `src/server.ts`).

***

### Task T011 - Skip Cloudflare Worker plugin for demo-pages builds

**Started**: 2026-06-24 00:34 **Completed**: 2026-06-24 00:35 **Duration**: 1 minute

**Notes**:

* Changed plugin assembly so `cloudflare({ viteEnvironment: { name: "ssr" } })` runs only for `command === "build"` when `isDemoPagesMode` is false.
* Normal build mode still retains the Worker plugin path.

**Files Changed**:

* `vite.config.ts` - guarded the Cloudflare Worker plugin behind `!isDemoPagesMode`.

**Verification**:

* Command/check: `bun run typecheck`
  * Result: PASS - Vite config typechecks after the plugin branch.
  * Evidence: `tsc --noEmit` exited 0.
* Command/check: `rg -n "cloudflare\\(|isDemoPagesMode" vite.config.ts`
  * Result: PASS - plugin guard inspected.
  * Evidence: Cloudflare plugin call is gated by `command === "build" && !isDemoPagesMode`.
* UI product-surface check: N/A - build configuration only.
* UI craft check: N/A - no UI files changed.

***

### Task T010 - Derive demo-pages build mode in Vite config

**Started**: 2026-06-24 00:32 **Completed**: 2026-06-24 00:34 **Duration**: 2 minutes

**Notes**:

* Refactored the Vite config callback to load Vite env once per mode.
* Added `isDemoPagesBuildMode()` derived from `mode === "demo-pages"` or the shared `VITE_AI_OS_PUBLIC_DEMO` parser using process/loaded Vite env.
* Ensured demo-pages mode defines `import.meta.env.VITE_AI_OS_PUBLIC_DEMO` as `"1"` for browser code even if the shell env flag is omitted.
* Dev middleware remains in the existing dev-server plugin; this task only changed build-mode derivation and env defines.

**Files Changed**:

* `vite.config.ts` - added public-demo env derivation and demo-pages mode flag.

**Verification**:

* Command/check: `bun run typecheck`
  * Result: PASS - TypeScript config and Vite config compile.
  * Evidence: `tsc --noEmit` exited 0.
* Command/check: `sed -n '230,470p' vite.config.ts`
  * Result: PASS - edited Vite helper and config callback inspected.
  * Evidence: `isDemoPagesBuildMode()` uses mode plus shared public-demo parsing, and `getViteEnvDefine()` forces browser public-demo env for demo-pages mode.
* UI product-surface check: N/A - build configuration only.
* UI craft check: N/A - no UI files changed.

**BQC Fixes**:

* Contract alignment: Vite config uses the same public-demo parser as app code (`vite.config.ts`, `src/lib/public-demo.ts`).

***

### Task T009 - Extend registry and setup-config tests

**Started**: 2026-06-24 00:31 **Completed**: 2026-06-24 00:32 **Duration**: 1 minute

**Notes**:

* Added registry coverage for public-demo forced all-extension behavior when normal extension env is unset or set to `none`.
* Added registry coverage proving invalid public-demo values do not force extensions.
* Added setup-config coverage for public-demo forced extension visibility and invalid-flag fallback.

**Files Changed**:

* `src/lib/__tests__/extension-registry.test.ts` - added public-demo registry override tests.
* `src/lib/__tests__/setup-config-extensions.test.ts` - added public-demo setup config tests.

**Verification**:

* Command/check: `bun run test -- src/lib/__tests__/extension-registry.test.ts src/lib/__tests__/setup-config-extensions.test.ts`
  * Result: PASS - focused extension and setup tests passed together.
  * Evidence: 2 test files passed; 42 tests passed.
* Command/check: `rg -n "VITE_AI_OS_PUBLIC_DEMO" src/lib/__tests__/extension-registry.test.ts src/lib/__tests__/setup-config-extensions.test.ts`
  * Result: PASS - public-demo env coverage inspected.
  * Evidence: Tests cover unset normal env, `none`, true values, and invalid public-demo values.
* UI product-surface check: N/A - this task changed non-UI tests.
* UI craft check: N/A - no UI files changed.

**BQC Fixes**:

* State freshness on re-entry: tests restore or unstub env state after each case to prevent cross-test leakage (`src/lib/__tests__/extension-registry.test.ts`, `src/lib/__tests__/setup-config-extensions.test.ts`).

***

### Task T008 - Surface public-demo setup extension visibility

**Started**: 2026-06-24 00:30 **Completed**: 2026-06-24 00:31 **Duration**: 1 minute

**Notes**:

* `getSetupEnvConfig()` now reports all registered extension IDs as enabled and locked by `VITE_AI_OS_PUBLIC_DEMO` when public-demo mode is active.
* Normal `VITE_CLAUDE_OS_ENABLED_EXTENSIONS` parsing remains unchanged outside public-demo mode.

**Files Changed**:

* `src/lib/setup-config.ts` - added public-demo forced extension visibility reporting.

**Verification**:

* Command/check: `bun run test -- src/lib/__tests__/setup-config-extensions.test.ts`
  * Result: PASS - existing setup extension env behavior still passes.
  * Evidence: 1 test file passed; 16 tests passed.
* Command/check: `sed -n '1,230p' src/lib/setup-config.ts`
  * Result: PASS - setup config branch inspected.
  * Evidence: public-demo mode sets `enabledExtensions.envVar` to `VITE_AI_OS_PUBLIC_DEMO`, value to registered IDs, and `locked` to true.
* UI product-surface check: N/A - this task changed setup config data only.
* UI craft check: N/A - no UI files changed.

**BQC Fixes**:

* Contract alignment: setup/status config now uses the shared public-demo helper and reports the same forced extension set as the registry (`src/lib/setup-config.ts`).

***

### Task T007 - Wire public-demo registry visibility

**Started**: 2026-06-24 00:29 **Completed**: 2026-06-24 00:30 **Duration**: 1 minute

**Notes**:

* `getEnabledExtensions()` now returns every statically registered extension when `VITE_AI_OS_PUBLIC_DEMO` is active.
* Normal extension env parsing remains the fallback path outside public-demo mode.

**Files Changed**:

* `src/extensions/registry.ts` - added public-demo registry override.

**Verification**:

* Command/check: `bun run test -- src/lib/__tests__/extension-registry.test.ts`
  * Result: PASS - existing registry behavior still passes.
  * Evidence: 1 test file passed; 20 tests passed.
* Command/check: `sed -n '1,80p' src/extensions/registry.ts`
  * Result: PASS - registry branch inspected.
  * Evidence: public-demo mode returns `extensions` before parsing `VITE_CLAUDE_OS_ENABLED_EXTENSIONS`.
* UI product-surface check: N/A - this task changed registry data selection only.
* UI craft check: N/A - no UI files changed.

**BQC Fixes**:

* Contract alignment: the registry uses the shared public-demo helper instead of duplicating flag parsing (`src/extensions/registry.ts`).

***

### Task T006 - Add public-demo helper tests

**Started**: 2026-06-24 00:29 **Completed**: 2026-06-24 00:29 **Duration**: 1 minute

**Notes**:

* Added focused tests for explicit true values, false values, invalid values, missing values, whitespace and case handling.
* Added coverage proving public-demo mode does not infer from `isExample`.
* Tightened `parsePublicDemoFlag()` so non-string values are false, matching the env-string contract.

**Files Changed**:

* `src/lib/__tests__/public-demo.test.ts` - created public-demo helper test suite.
* `src/lib/public-demo.ts` - tightened parser handling for non-string values.

**Verification**:

* Command/check: `bun run test -- src/lib/__tests__/public-demo.test.ts`
  * Result: PASS - focused helper tests passed.
  * Evidence: 1 test file passed; 26 tests passed.
* Command/check: `rg -n "isExample" src/lib/__tests__/public-demo.test.ts src/lib/public-demo.ts`
  * Result: PASS - `isExample` appears only in the no-coupling test.
  * Evidence: Helper implementation has no `isExample` references.
* UI product-surface check: N/A - this task changed non-UI helper tests.
* UI craft check: N/A - no UI files changed.

**BQC Fixes**:

* Contract alignment: parser and tests now agree that only string env true values activate public demo mode (`src/lib/public-demo.ts`, `src/lib/__tests__/public-demo.test.ts`).

***

### Task T005 - Add public-demo Vite env typing

**Started**: 2026-06-24 00:28 **Completed**: 2026-06-24 00:29 **Duration**: 1 minute

**Notes**:

* Added `VITE_AI_OS_PUBLIC_DEMO` to `ImportMetaEnv`.
* Verified the project already includes Vite client types through `tsconfig.json`.

**Files Changed**:

* `src/vite-env.d.ts` - added public-demo Vite env typing.

**Verification**:

* Command/check: `sed -n '1,40p' src/vite-env.d.ts`
  * Result: PASS - env declaration inspected.
  * Evidence: `ImportMetaEnv` now declares optional `VITE_AI_OS_PUBLIC_DEMO`.
* Command/check: `sed -n '1,80p' tsconfig.json`
  * Result: PASS - TypeScript config inspected.
  * Evidence: `types` includes `vite/client`, and `src/**/*.ts` includes local declaration files.
* UI product-surface check: N/A - this task changed typing only.
* UI craft check: N/A - no UI files changed.

***

### Task T004 - Create public-demo flag helper

**Started**: 2026-06-24 00:26 **Completed**: 2026-06-24 00:28 **Duration**: 2 minutes

**Notes**:

* Added a shared parser for `VITE_AI_OS_PUBLIC_DEMO` that returns true only for explicit true values.
* Added an env-object helper for build/config callers and a browser helper for app code.
* Kept the helper independent of LiveData and `isExample`.

**Files Changed**:

* `src/lib/public-demo.ts` - created public-demo parser and browser helper.

**Verification**:

* Command/check: `sed -n '1,120p' src/lib/public-demo.ts`
  * Result: PASS - helper implementation inspected.
  * Evidence: true values are limited to `1`, `true`, `yes`, and `on`; absent, non-string, and invalid values return false.
* Command/check: `rg -n "isExample|LiveData|__live-data" src/lib/public-demo.ts`
  * Result: PASS - no fallback-data coupling found.
  * Evidence: Search returns no matches.
* UI product-surface check: N/A - this task added a non-UI helper.
* UI craft check: N/A - no UI files changed.

**BQC Fixes**:

* Contract alignment: public-demo parsing is centralized in one helper so build config and browser code use the same true-value contract (`src/lib/public-demo.ts`).

***

### Task T003 - Create implementation evidence log

**Started**: 2026-06-24 00:23 **Completed**: 2026-06-24 00:26 **Duration**: 3 minutes

**Notes**:

* Created the implementation log before marking any checklist tasks complete.
* Recorded environment checks, active session resolution, local tool availability, and setup/inventory task evidence.
* Resolved the generic tool prereq warning by confirming project-local binaries exist and package scripts use them through Bun.

**Files Changed**:

* `.spec_system/specs/phase31-session01-demo-mode-foundation/implementation-notes.md` - added session evidence log.

**Verification**:

* Command/check: `test -s .spec_system/specs/phase31-session01-demo-mode-foundation/implementation-notes.md`
  * Result: PASS - implementation notes file exists and is non-empty.
  * Evidence: File was created with session metadata, progress table, environment evidence, and per-task log sections.
* Command/check: `find node_modules/.bin -maxdepth 1 -type f -o -type l | rg '/(vitest|tsc|vite)$'`
  * Result: PASS - project-local test/build tools are installed.
  * Evidence: `node_modules/.bin/vitest`, `node_modules/.bin/tsc`, and `node_modules/.bin/vite` are present.
* UI product-surface check: N/A - this task created workflow documentation only.
* UI craft check: N/A - no UI files changed.

***

### Task T002 - Inventory public-demo-adjacent code paths

**Started**: 2026-06-24 00:24 **Completed**: 2026-06-24 00:25 **Duration**: 1 minute

**Notes**:

* `useLiveData()` fetches `/__live-data` and falls back to `DEFAULT_LIVE_DATA`; no public-demo branch exists yet.
* `validate-live-data.ts` owns `isExample` as a required LiveData key with `DEFAULT_LIVE_DATA.isExample = true`; public-demo mode can remain separate.
* `extensions/registry.ts` currently derives enabled extensions only from `VITE_CLAUDE_OS_ENABLED_EXTENSIONS`.
* `setup-config.ts` centralizes env list and boolean parsing and currently reports extension locks only from `VITE_CLAUDE_OS_ENABLED_EXTENSIONS`.
* `vite.config.ts` currently adds `cloudflare({ viteEnvironment: { name: "ssr" } })` for every build and passes normal `tanstackStart()` options without SPA mode.
* Installed TanStack Start exposes `spa: { enabled, maskPath, prerender }` and `createStart` exposes `defaultSsr`, so the demo branch can use supported local dependency options.

**Files Changed**:

* `.spec_system/specs/phase31-session01-demo-mode-foundation/implementation-notes.md` - recorded code inventory evidence.

**Verification**:

* Command/check: `sed -n '1,220p' src/lib/use-live-data.ts`
  * Result: PASS - live data fetch boundary inspected.
  * Evidence: Hook fetches `/__live-data` and returns `DEFAULT_LIVE_DATA` when query data is absent.
* Command/check: `sed -n '1,430p' src/lib/validate-live-data.ts`
  * Result: PASS - fallback data semantics inspected.
  * Evidence: `isExample` is a required LiveData key and default fallback data sets it to `true`.
* Command/check: `sed -n '1,260p' src/extensions/registry.ts`
  * Result: PASS - extension enablement boundary inspected.
  * Evidence: `getEnabledExtensions()` parses only `VITE_CLAUDE_OS_ENABLED_EXTENSIONS` today.
* Command/check: `sed -n '1,280p' src/lib/setup-config.ts`
  * Result: PASS - setup env config boundary inspected.
  * Evidence: extension config uses `parseEnabledExtensionIds()` and locks based on that env value.
* Command/check: `sed -n '1,1400p' vite.config.ts`
  * Result: PASS - build and dev middleware boundaries inspected.
  * Evidence: Cloudflare plugin is build-only, TanStack Start has no SPA option yet, and local bridge middleware is inside a dev-server plugin.
* Command/check: `sed -n '150,320p' node_modules/@tanstack/start-plugin-core/src/schema.ts`
  * Result: PASS - installed SPA option shape inspected.
  * Evidence: local schema defines `spa.enabled`, `spa.maskPath`, and SPA prerender shell behavior.
* UI product-surface check: N/A - this task inspected code only.
* UI craft check: N/A - no UI files changed.

### Task T001 - Verify requirements and Worker build assumptions

**Started**: 2026-06-24 00:23 **Completed**: 2026-06-24 00:24 **Duration**: 1 minute

**Notes**:

* Verified Phase 31 requires a public-safe static Cloudflare Pages demo without changing the normal Worker deployment path.
* Verified Session 01 owns only the public-demo build-mode foundation, extension visibility override, and build separation.
* Verified Phase 30 validation passed with normal build, typecheck, test, private-runtime, and ASCII/LF evidence.
* Confirmed current Worker build assumptions from requirements: normal `bun run build` emits `dist/client` and `dist/server/wrangler.json`, while demo-pages must skip Worker SSR plumbing and emit static HTML.

**Files Changed**:

* `.spec_system/specs/phase31-session01-demo-mode-foundation/implementation-notes.md` - recorded requirement and prerequisite evidence.

**Verification**:

* Command/check: `sed -n '1,260p' .spec_system/PRD/phase_31/PRD_phase_31.md`
  * Result: PASS - phase requirements inspected.
  * Evidence: PRD states static-only Pages demo, no Pages Functions/SSR/local bridge behavior, and normal Worker deployment preservation.
* Command/check: `sed -n '1,260p' .spec_system/PRD/phase_31/session_01_demo_mode_foundation.md`
  * Result: PASS - session scope inspected.
  * Evidence: Session 01 lists public-demo flag detection, demo-pages Vite branch, Worker plugin skip, SPA output, and extension visibility override.
* Command/check: `sed -n '1,260p' .spec_system/specs/phase30-session10-quality-gates-and-enablement/validation.md`
  * Result: PASS - prerequisite evidence inspected.
  * Evidence: Phase 30 validation result is PASS with 20/20 tasks complete and full quality gates passing.
* UI product-surface check: N/A - this task inspected requirements only.
* UI craft check: N/A - no UI files changed.

### 2026-06-24 - Session Start

**Environment verified**:

* [x] Prerequisites confirmed with `bash .spec_system/scripts/analyze-project.sh --json`
* [x] Environment confirmed with `bash .spec_system/scripts/check-prereqs.sh --json --env`
* [x] Directory structure ready
* [x] Project-local tools available through `node_modules/.bin`

**Notes**:

* Active session resolved to `phase31-session01-demo-mode-foundation`.
* Repo is not detected as a monorepo by the spec scripts.
* Generic tool prereq lookup did not find global `vitest`, `tsc`, or `vite`, but `node_modules/.bin/vitest`, `node_modules/.bin/tsc`, and `node_modules/.bin/vite` are present and package scripts use them through Bun.
* No database layer is present for this session.

# 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/phase31-session01-demo-mode-foundation/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.
