# Phase 0 feasibility attempt — September 4, 2026
|
||||
|
||||
**Gate:** GC1 / direct-file launch\
|
||||
**Result:** BLOCKED by browser tool policy; browser behavior NOT TESTED\
|
||||
**PRD revision:** 0.2 (XZBT format 0.1)\
|
||||
**Git baseline:** `05fe2b4e021ba86e4a290d05b63c7cae0e386128`\
|
||||
**Probe SHA-256:** `01EBF91DBD1257C8099DCCC80FE3937EEFBF39819568DD7FB4B5482C2756CE5C`
|
||||
|
||||
## Environment observed
|
||||
|
||||
Recorded at `2026-09-04T18:47:45.9013932-07:00`:
|
||||
|
||||
- Windows 11 Pro, version `10.0.26200`, build `26200`.
|
||||
- Intel Core i7-13700F.
|
||||
- NVIDIA GeForce RTX 4060 Ti, driver `32.0.16.1656`; Parsec Virtual Display Adapter also present.
|
||||
- Installed Chrome `152.0.7977.77` and Edge `152.0.4191.62`, identified from executable version metadata only. Neither was launched or tested by this attempt.
|
||||
- Node.js `v24.11.0` and npm `11.12.1`.
|
||||
- Browser tooling selected the Codex in-app browser. Its page engine version, viewport, storage mode, and profile persistence were not observed because navigation was denied.
|
||||
|
||||
## Artifact and static check
|
||||
|
||||
Artifact: [XZBT-phase0-probe.html](../../../prototypes/phase0/XZBT-phase0-probe.html). Fixtures: [Amber Study](../../../prototypes/phase0/fixtures/amber-study.xzbt) and [Blue Study](../../../prototypes/phase0/fixtures/blue-study.xzbt).
|
||||
|
||||
The probe is intentionally separate from the production runtime. It uses the isolated database name `xzbt-phase0-probe-v1`, performs no authored network requests, and does not read local credentials. A Content Security Policy disallows network connections and external resources. These source-level properties are not a completed browser offline test.
|
||||
|
||||
Node's `vm.Script` successfully parsed the HTML's inline script. `JSON.parse` successfully parsed both fixture files. The static check reported:
|
||||
|
||||
```text
|
||||
Probe JavaScript and both JSON fixtures parse successfully.
|
||||
```
|
||||
|
||||
## Browser attempt
|
||||
|
||||
Requested navigation:
|
||||
|
||||
```text
|
||||
file:///G:/.vibe/XZBT/prototypes/phase0/XZBT-phase0-probe.html
|
||||
```
|
||||
|
||||
Expected: the probe loads from disk, reports environment and IndexedDB availability, and permits user-initiated fixture import.
|
||||
|
||||
Actual: the browser tool rejected navigation before a page snapshot or probe result was available. Its reason was: "The browser URL policy blocks this action." The response also explicitly prohibited workarounds through indirect execution, raw CDP/browser commands, or alternate browser surfaces.
|
||||
|
||||
This is not an IndexedDB error, AudioWorklet error, failed prototype assertion, or evidence that direct-file Chromium operation is impossible. No browser acceptance result can be inferred from this rejection.
|
||||
|
||||
## Checks not performed
|
||||
|
||||
- Actual offline loading and browser environment capture.
|
||||
- File-picker and directory import.
|
||||
- Cache writes, settings changes, and restoration after a full browser restart.
|
||||
- Audio unlock, Blob worklet loading, and suspend/resume.
|
||||
- Rename/move storage behavior.
|
||||
- Injected storage-failure behavior or real browser storage-denial behavior.
|
||||
- Any performance, conformance, or soak testing.
|
||||
|
||||
No GC1 acceptance box is marked passed based on the static checks. Phase 0 remains incomplete and Phase 1 was not started.
|
||||
|
||||
## Required next evidence
|
||||
|
||||
The user can open the artifact directly in desktop Chrome or Edge and follow the [manual procedure](../../../prototypes/phase0/README.md). Capture the on-page evidence after import/settings changes and again after fully closing and reopening the browser. Record failures and cancelled permissions distinctly from passes. On receipt of that evidence, review GC1 before resuming the remaining Phase 0 work.

# Phase 0 renamed and relocated copies
|
||||
|
||||
**Result:** Passed as user-reported manual evidence.
|
||||
|
||||
The requested procedure was to open a renamed copy of probe version 3 in the same folder, then another copy in a different folder, and report restoration before importing or changing anything. The user replied: “yes, each restored exhibit and settings”.
|
||||
|
||||
Both copies therefore recovered the cached exhibits and settings in the tested browser environment. This observation does not support assuming storage is isolated by individual HTML filename or containing folder. Keep the runtime database namespaced and treat same-profile copies as potentially sharing cached state.
|
||||
|
||||
The exact alternate paths and separate JSON captures were not supplied. The browser environment is inherited from the ongoing manual Chrome 152 test; no cross-profile, cross-browser, or cross-device behavior was tested. Restoration after renaming or relocating is observed here, not guaranteed for every browser configuration. The supported baseline remains the tested same-file restart behavior, with file import and session operation available when persistence is unavailable.
|
||||
|
||||
The GC1 rename/move observation check is complete. Offline, remaining import/fallback, and browser profile/storage-mode observations remain pending. Phase 0 shared contracts also remain unfinished.

# Phase 0 browser mode and ordinary file import
|
||||
|
||||
**Result:** Regular-browser environment and ordinary import/activation checks passed as user-reported manual evidence.
|
||||
|
||||
The assistant asked whether the user was using a regular Chrome window rather than Incognito, and whether importing through the ordinary file input and selecting each exhibit worked. The user answered: “yes, regular chrome, yes everything worked”. This confirms both requested observations; it is not a claim that every outstanding project test passed.
|
||||
|
||||
The preceding records identify Windows, Chrome 152, the original direct-file launch path, and IndexedDB storage. Combined with this confirmation, the tested storage mode is a regular, non-Incognito Chrome profile. A profile name or personal account identifier is not required. The mobile user agent in the offline run remains an environment variation, not evidence from a physical Android device.
|
||||
|
||||
Ordinary file-input import and activation of both Amber Study and Blue Study passed. Directory import separately succeeded in the storage-failure run. Neither confirmation demonstrates actual directory permission denial or API unavailability; that conditional fallback portion remains unverified. Remembered source handles are optional and are not implemented in this disposable probe.
|
||||
|
||||
Phase 0 remains incomplete: the conditional directory fallback observation and shared contracts, semantic traces, and milestone preparation are still outstanding. No Phase 1 implementation is established by these manual probe results.

# Phase 0 audio follow-up with changed user agent
|
||||
|
||||
**Result:** Offline restoration, native tone, and data-URL worklet passed as user-performed manual evidence.
|
||||
|
||||
The [user-supplied evidence](2026-09-04-user-offline-audio.json) records a page start at `2026-09-05T03:01:55.614Z`, successful cache restoration, a heard tone with completed node cleanup, and successful worklet loading and connection at `2026-09-05T03:02:40.836Z`. The audio context runs at 48,000 Hz. No errors or policy violations were reported.
|
||||
|
||||
The user agent now identifies Android 15 / Pixel 9 / Mobile Chrome 152, while platform remains Win32 and the URL remains the original Windows file path. Viewport is 1186 × 872 with DPR 2. This is consistent with desktop device emulation, but its activation was not explicitly confirmed. It does not establish behavior on a physical Android device.
|
||||
|
||||
After being asked whether the browser network setting was explicitly Offline throughout this run, the user confirmed: “Yes, it was set to offline”. This manual confirmation establishes the test condition and completes the offline probe check. The raw JSON remains unchanged: `onlineFlag` is true and authored requests are zero. Neither field alone establishes offline operation; the result relies on the user's confirmation together with the observed restoration and audio/worklet results. This was browser-scoped offline testing, not a change to system networking.
|
||||
|
||||
Both fixture definitions are restored, but activation of each is not captured. Remaining import/fallback and browser profile/storage-mode observations remain separate checks. This result does not complete Phase 0 or establish offline conformance of a production runtime.

# Phase 0 initial capture after offline-test instructions
|
||||
|
||||
**Result:** Partial; offline acceptance remains open.
|
||||
|
||||
The [supplied capture](2026-09-04-user-offline-initial.json) starts at `2026-09-05T03:00:54.788Z` on the original direct-file probe version 3. Both exhibits and saved settings restored, including Blue activity 0.37 and master volume 0.19. There were zero new saves and no errors.
|
||||
|
||||
The capture was supplied after instructions to disable networking within the test browser, reload, select each exhibit, and test the tone and worklet. It contains no explicit confirmation of the developer-tool offline setting. `onlineFlag` remains true and `networkRequestsAuthored` is zero; these fields do not establish that networking was disabled. Audio, tone, and worklet are all marked not tested. Activation of each exhibit is not demonstrated by this capture.
|
||||
|
||||
Keep the offline gate unchecked pending confirmation of browser-scoped offline mode and the requested interaction results. No runtime defect is established by this initial capture. Earlier successful audio and worklet evidence remains valid for its original test conditions.

# Phase 0 user-performed restart and edited-settings restoration
|
||||
|
||||
**Result:** Passed as a user-performed manual restart test following the requested procedure\
|
||||
**Evidence:** [Supplied JSON](2026-09-04-user-restart.json)\
|
||||
**Page started:** `2026-09-05T02:43:23.096Z`\
|
||||
**State saved:** `2026-09-05T02:42:54.030Z`\
|
||||
**Probe:** Version 3, same artifact as the successful worklet test
|
||||
|
||||
## Procedure provenance
|
||||
|
||||
The user clarified that the earlier tests were reloads. The assistant then explicitly requested: set activity to 0.37 and volume to 0.19, wait for the save, fully exit Chrome, reopen the same file, and provide evidence before making any changes. The user supplied this record in response. The full-restart action is accepted from that manual-test context; the JSON itself and the agent do not independently attest to browser-process termination. Earlier reload-only records are not retroactively classified as restart tests.
|
||||
|
||||
## Observed result
|
||||
|
||||
Both exhibits, Blue Study selection, and saved settings were present immediately after loading the same `file:` URL. `restored` is true and `saves` is zero. `restoredAtLoad` and `current` agree:
|
||||
|
||||
| Setting | Saved/restored value |
|
||||
| --- | --- |
|
||||
| Amber Study activity | 0.25 |
|
||||
| Blue Study activity | 0.37 |
|
||||
| Master volume | 0.19 |
|
||||
| Selected exhibit | blue-study |
|
||||
|
||||
The Blue activity and master-volume values differ from their declared/initial defaults, demonstrating recovery of edited values rather than initialization from defaults. No error was reported. There was no need to re-import either fixture.
|
||||
|
||||
Audio and worklet are correctly marked `not tested` on this new page load. The earlier successful audio/worklet evidence remains valid; these per-load statuses are not regressions and do not require another audio test for this persistence check.
|
||||
|
||||
## Gate effect and remaining work
|
||||
|
||||
Mark the GC1 full-browser-reopen/cache-and-settings check passed as user-performed manual evidence. The underlying worklet-loading blocker is already resolved. GC1 still needs offline, storage-failure, rename/move, and remaining import/fallback/environment observations. Phase 0 shared contracts and semantic traces also remain unfinished, and Phase 1 has not begun.

# Phase 0 version 2 results and version 3 candidate fix
|
||||
|
||||
**Result:** Cache restored between loads; tone heard; suspend/resume observed; Blob worklet loading failed\
|
||||
**Source:** User-supplied [version 2 JSON](2026-09-04-user-run-v2.json)\
|
||||
**Run started:** `2026-09-05T02:26:04.668Z` (September 4 in America/Los_Angeles)\
|
||||
**Gate:** GC1 remains incomplete; no advancement to Phase 1
|
||||
|
||||
## Findings
|
||||
|
||||
| Check | Evidence | Conclusion |
|
||||
| --- | --- | --- |
|
||||
| Direct-file load | `protocol: "file:"`, secure context, Chrome 152 | Observed in the user's browser |
|
||||
| Restore on a later load | `restored: true`, `saves: 0`, populated `restoredAtLoad` | Both exhibits, Blue selection, and saved default parameter/volume values restored without a write in this run |
|
||||
| Link to previous saved state | `savedAt: 2026-09-05T02:14:24.015Z` | Matches the preceding user-run save timestamp |
|
||||
| Full browser restart | No independent confirmation of process exit | Still unverified; a later page load alone is insufficient |
|
||||
| Distinctive edited settings | Values remain at defaults | Edited-value reconciliation/restoration is not demonstrated by this run |
|
||||
| Native tone | `toneHeard: true`, tone ended and nodes disconnected | User confirms audible output |
|
||||
| Suspend/resume | `suspendObserved: "suspended"`, `resumeObserved: "running"` | AudioContext state changes observed |
|
||||
| Worklet | `addModule` rejected a `blob:null/...` URL while the context remained running | Failure isolated to module loading; node construction was not reached |
|
||||
| CSP | Empty `securityPolicyViolations` list | No page violation event captured; this does not prove absence of every browser restriction |
|
||||
| Offline/directory/fault injection | Online flag true; directory untested; injection false | These checks remain pending |
|
||||
|
||||
This run resolves the uncertainty about native audio output and demonstrates actual cache restoration between loads. It does not establish that all of GC1 passed.
|
||||
|
||||
## Candidate module-loading correction
|
||||
|
||||
The combination of a local `file:` page, an opaque `blob:null` URL, and an `addModule` failure is consistent with a local Blob-module loading limitation. This remains a diagnosis to verify, not a proven universal restriction in Chrome 152.
|
||||
|
||||
The [Recorder project's own implementation](https://raw.githubusercontent.com/xiangyuecn/Recorder/master/src/recorder-core.js) constructs a `data:text/javascript;base64,...` worklet module URL, with an explicit source comment explaining that some browsers reject local object URLs. This primary implementation informed the candidate fix; no Recorder dependency or code was imported into XZBT.
|
||||
|
||||
Probe version 3 encodes the same fixed ASCII processor source into a `data:` URL and passes it to the same `audioWorklet.addModule()` API. It replaces `blob:` with `data:` in the page's `script-src` allowlist. It does not disable CSP, add network sources, enable eval, change browser flags, or accept exhibit-authored executable modules. `connect-src 'none'` remains in effect. This changes application packaging, not the agent browser tool's URL policy; no blocked browser automation was attempted.
|
||||
|
||||
The probe's database and path remain unchanged. Attempt evidence now reports `moduleURLScheme: "data:"` and the fixed source size. Success would be reported as `loaded from engine-owned data URL and connected`; it must not be recorded until an actual user browser run reports it.
|
||||
|
||||
**Version 3 artifact SHA-256:** `97D6909953F1F22E5BF0CA8AD653605D57A078AB3CCDEDFA509C5E9B0C1A4B2A`
|
||||
|
||||
## Verification performed
|
||||
|
||||
Three Node control-flow regression tests passed using `node --test prototypes/phase0/audio-probe.test.mjs`. These use stubbed APIs. They cover rejection isolation, diagnostics, the embedded processor source's syntax, data URL construction, and avoiding duplicate registration after simulated success. They do not verify real browser module loading or CSP enforcement.
|
||||
|
||||
## Next evidence
|
||||
|
||||
Reopen the same [probe file](../../../prototypes/phase0/XZBT-phase0-probe.html), verify `probeVersion: 3`, enable audio, and test the worklet module. Share the evidence and any additional browser console error if it still fails. Confirm separately whether Chrome was fully exited between the earlier user runs. Preserve the remaining offline, edited-settings, directory/fallback, and failure-injection checks in the [manual procedure](../../../prototypes/phase0/README.md).

# Phase 0 version 3 — worklet loading verified
|
||||
|
||||
**Result:** Engine-owned data-URL worklet loaded and connected in the user's direct-file Chrome session\
|
||||
**Source:** [User-supplied version 3 evidence](2026-09-04-user-run-v3.json)\
|
||||
**Page started:** `2026-09-05T02:37:48.163Z`\
|
||||
**Worklet attempt:** `2026-09-05T02:38:39.380Z`\
|
||||
**Artifact SHA-256:** `97D6909953F1F22E5BF0CA8AD653605D57A078AB3CCDEDFA509C5E9B0C1A4B2A`
|
||||
|
||||
Timestamps are UTC; both fall on September 4 in America/Los_Angeles. This record uses the user's final version 3 snapshot after the worklet button was pressed. The earlier snapshot from the same page load contained no worklet attempt and is not used as a worklet pass.
|
||||
|
||||
## Verified observations
|
||||
|
||||
- The page ran at the expected `file:///G:/.vibe/XZBT/prototypes/phase0/XZBT-phase0-probe.html` URL in Chrome 152, with `secureContext: true`.
|
||||
- `addModule` and node construction completed. The attempt reached `connect node`, returned `loaded and connected`, and recorded `moduleURLScheme: "data:"` and `moduleSourceBytes: 226`.
|
||||
- AudioContext state was running before and after the attempt at 48000 Hz. The user marked the native test tone as heard; the tone's nodes were disconnected when it ended.
|
||||
- No errors or page security-policy violations were recorded in this run.
|
||||
- Both exhibits, Blue Study selection, parameters, and master volume restored on page load, with zero new saves. The saved timestamp matches the earlier version 1 run.
|
||||
|
||||
The version 3 change resolves the observed Blob-module loading blocker in this tested environment. Use an engine-owned embedded data URL for this direct-file packaging path. Do not infer universal browser support or a complete audio-engine acceptance result from this small probe.
|
||||
|
||||
The silent processor's render callbacks are not independently measured; this gate verifies loading, construction, and connection. Native tone output and worklet loading are separate observations. Full synthesis correctness, output protection, performance, and long-running behavior remain later tests.
|
||||
|
||||
## Gate accounting
|
||||
|
||||
GC1's engine-owned AudioWorklet loading check is passed using user-run browser evidence. The cache save check is supported by the earlier save transactions plus actual restoration in versions 2 and 3. Native audio unlock/tone and AudioContext suspend/resume are supported across the version 2 and version 3 records.
|
||||
|
||||
GC1 is not complete. Remaining evidence includes:
|
||||
|
||||
1. Confirmation of a full browser exit/restart, rather than only a new page load, and restoration of distinctive edited parameter/volume values.
|
||||
2. Offline operation in an isolated test browser; the latest evidence still reports the browser online.
|
||||
3. Rename/move storage behavior and the documented support boundary.
|
||||
4. Session playback with storage failure injected, including the user-facing persistence message.
|
||||
5. Browser profile/storage mode details and the remaining import/fallback checks. Directory APIs are optional enhancements; capability presence alone is not an import test.
|
||||
|
||||
The [manual procedure](../../../prototypes/phase0/README.md) covers these checks. No further worklet retest is needed unless its source, loader, or relevant policy changes. The agent's direct-file navigation restriction remains; no alternate browser automation was used.
|
||||
|
||||
Phase 0 still requires the remaining shared contracts and semantic traces after feasibility verification. Phase 1 has not started.

# Phase 0 user-run evidence and probe correction
|
||||
|
||||
**Result:** Partial feasibility demonstrated; worklet load failed; GC1 remains incomplete\
|
||||
**Source:** JSON supplied by the user from probe version 1\
|
||||
**Run started:** `2026-09-05T02:13:55.036Z` (September 4 in America/Los_Angeles)\
|
||||
**Raw evidence:** [user-run JSON](2026-09-04-user-run.json)
|
||||
|
||||
The raw evidence is preserved with its original field values, including the misleading `worklet: "not tested"` status. No agent browser navigation or workaround was used to obtain this result.
|
||||
|
||||
## What this run establishes
|
||||
|
||||
| Observation | Assessment |
|
||||
| --- | --- |
|
||||
| `protocol: "file:"`, Chrome 152 user agent, `secureContext: true` | The user loaded the probe directly from disk in a secure context |
|
||||
| Both exhibits present; Blue Study selected | File import and selection produced the shown library state |
|
||||
| `indexedDB: "opened and read"`, `saves: 2` | The probe reports an opened database and two completed save transactions |
|
||||
| `audioState: "running"`, sample rate 48000 | The audio context was unlocked and running |
|
||||
| Three `AbortError` entries for module loading | Worklet loading failed; it was attempted despite the stale status label |
|
||||
| `restored: false` | This document load did not restore cached state; it does not establish a full-restart test or prove persistence failure |
|
||||
| Both activity values and master volume still at defaults | Distinctive edited preference restoration has not been demonstrated |
|
||||
| `onlineFlag: true`, authored-network count 0 | No offline test is established; the count is a source-level declaration, not a network trace |
|
||||
| Directory import not tested; storage injection false | These checks remain pending |
|
||||
|
||||
The v1 worklet attempt occurs before oscillator creation and before enabling suspend/resume. Each shown exception therefore prevented that invocation from scheduling its tone and enabling those controls. A running context is not evidence of audible output.
|
||||
|
||||
## Root cause status
|
||||
|
||||
The cause of module-load failure is not established. Chromium uses the reported AbortError wording for worklet module-load failures; it does not uniquely identify CSP, origin behavior, or a processor-code defect. See the [Chromium diagnostic change](https://chromium.googlesource.com/chromium/src/+/963f877152d08f60e3f8bd60f1958ddcebce3b0f).
|
||||
|
||||
The [Fetch Standard](https://fetch.spec.whatwg.org/#concept-request-destination) associates `audioworklet` requests with `script-src`. This probe already permits `blob:` in `script-src`. That is insufficient to diagnose this run, but does not justify assuming `connect-src 'none'` is the cause or weakening the policy without evidence. Console details and captured policy violations are the next diagnostic input.
|
||||
|
||||
## Probe version 2
|
||||
|
||||
The corrected [probe](../../../prototypes/phase0/XZBT-phase0-probe.html) separates native tone playback from worklet loading, enables suspend/resume after context unlock, and records explicit worklet attempt stages and failure state. It adds an explicit user-reported audible-tone checkbox and page CSP diagnostics. The database name, file path, loader strategy, and CSP remain unchanged.
|
||||
|
||||
**Version 2 artifact SHA-256:** `52DD9137A7584236D00A7BF5BBBDB8159B25D8F98605C88A849892835B8D0FE5`
|
||||
|
||||
Two stubbed Node control-flow regression tests passed using:
|
||||
|
||||
```text
|
||||
node --test prototypes/phase0/audio-probe.test.mjs
|
||||
```
|
||||
|
||||
They verify that worklet rejection cannot prevent tone scheduling or suspend/resume controls and that supplied CSP diagnostics are retained. The tests use fake APIs and do not verify browser loading, CSP enforcement, audio output, or persistence. Browser testing of version 2 is pending.
|
||||
|
||||
## Next manual check
|
||||
|
||||
Follow the [updated instructions](../../../prototypes/phase0/README.md). Test the native tone and worklet independently; include `workletAttempts`, `securityPolicyViolations`, and any additional console error in the next evidence. Test distinctive values and capture the next launch before importing again, confirming separately whether the browser was fully closed.
|
||||
|
||||
Phase 0 remains stopped at the unresolved worklet/loading and restart-persistence checks. No Phase 1 implementation has begun.

# Phase 0 injected storage failure and directory import
|
||||
|
||||
**Result:** Passed for injected write failure: session settings, import, playback, and the visible session-only warning.\
|
||||
**Evidence:** [User-supplied JSON](2026-09-04-user-storage-failure.json)\
|
||||
**Page started:** `2026-09-05T02:48:47.748Z`\
|
||||
**Environment:** Probe 3, direct-file Chrome 152 on Win32, same original path and 1920 × 959 viewport as preceding runs.
|
||||
|
||||
The user supplied this capture after instructions to enable storage failure, change activity, and import the fixtures again. It records 16 save errors, all `QuotaExceededError` with message `Injected write failure.` These are expected application fault-injection results, not a new worklet or browser failure.
|
||||
|
||||
Blue Study activity changed from the restored 0.37 to 0.5 in memory. Both fixtures remain present, Blue remains selected, and master volume remains 0.19. Successful saves stayed at zero and the saved timestamp stayed at `2026-09-05T02:42:54.030Z`. Directory import completed and the imported names include both fixtures. This supports continued settings and import operation despite failed writes.
|
||||
|
||||
The initial JSON does not capture the visible session-only warning or demonstrate playback during the failure. Source inspection shows the warning is assigned when injection is checked, but this is not a user observation. This injection does not establish behavior under real browser permission denial or quota exhaustion.
|
||||
|
||||
## Follow-up audio observation
|
||||
|
||||
The [subsequent capture from the same page session](2026-09-04-user-storage-failure-audio.json) records injection still enabled, audio unlocked through user interaction, `toneHeard: true`, tone completion and node disconnection, and an AudioContext running at 48,000 Hz. The same 16 injected save errors remain, with no successful saves or additional audio errors. Native playback during injected storage failure therefore passes. Worklet testing was not repeated and is not required for this native-playback check. After being asked whether the “Session only: storage is unavailable” warning was visible, the user answered “yes” in chat. This explicit manual observation completes the injected-storage-failure check. The confirmation is recorded here separately from the unchanged raw JSON captures.
|
||||
|
||||
Directory import success is now observed. Remembered directory handles are not implemented by this disposable probe. Directory-denial/unavailability fallback and activation of each fixture remain unverified by this capture. Offline operation, renamed/moved-file storage boundaries, and browser profile/storage-mode details also remain outstanding. Phase 0 remains incomplete; Phase 1 has not started.
