XZBT implementation status
Updated: September 4, 2026
State: Stopped in Phase 0 at GC1; no later phase started
Baseline commit: 05fe2b4e021ba86e4a290d05b63c7cae0e386128
The user requested sequential implementation with a stop on problems. The manual version 3 evidence verifies embedded data-URL worklet loading in direct-file Chrome. The subsequent user-performed restart test restored Blue Study activity 0.37 and master volume 0.19 immediately on reopening. Native tone output and AudioContext suspend/resume are also observed. GC1 still awaits the directory-permission/unavailability fallback check. Ordinary file import, selection of both exhibits, and regular Chrome mode have been confirmed. The agent's direct-file browser-navigation restriction remains in effect.
| Phase | Status | Evidence or next prerequisite |
|---|---|---|
| 0 — Contracts and feasibility | Awaiting remaining manual evidence; incomplete | Restart/settings pass and outstanding checks |
| 1 — Runtime skeleton | Not started | Complete Phase 0 |
| 2 — Common grammar | Not started | Complete Phase 1 and shared contracts |
| 3 — Audio engine | Not started | Earlier phases and audio contracts |
| 4 — Visual engine | Not started | Earlier phases and visual contracts |
| 5 — Events and cadence | Not started | Earlier phases and event/cadence contracts |
| 6 — Scenario director | Not started | Earlier phases and scenario contracts |
| 7 — Dynamic UI | Not started | Earlier phases and UI contracts |
| 8 — Library and persistence hardening | Not started | Earlier phases and library contracts |
| 9 — Reference suite completion/audit | Not started | Earlier phases, challenge coverage, benchmark and soak evidence |
Work saved
- A self-contained Phase 0 probe for import, isolated probe caching, settings restoration, user-initiated audio, embedded engine worklet loading, suspend/resume, and injected storage failure.
- Two minimal import fixtures and manual test instructions.
- Syntax checks passed for the probe's JavaScript and both JSON fixtures. These checks do not establish browser behavior or complete GC1.
- Preserved the user's version 1 and version 2 evidence, including the failed Blob-module attempts. Version 2 separated tone/worklet tests and added failure diagnostics.
- Version 3 changes the fixed processor module from a Blob URL to an embedded data URL and adjusts the page script-source allowlist while continuing to block network connections. Three stubbed regression tests passed; the user's subsequent version 3 run now verifies real loading and connection in direct-file Chrome.
Resume condition
The injected-storage-failure run and audio follow-up confirm in-memory activity changes, successful directory import, and heard native playback despite 16 expected failed saves. The user subsequently confirmed the visible session-only warning. The injected-storage-failure check passed; this does not establish real browser permission-denial behavior.
Worklet loading and the user-performed restart/settings test have passed and need not be repeated without a relevant code change. The offline restoration, tone, and worklet check also passed with explicit user confirmation of browser-scoped Offline mode; see offline evidence. The user confirmed regular Chrome mode and ordinary import/activation. Directory-permission/unavailability fallback remains unverified. The earlier reload results remain distinct from the subsequent manual restart procedure.
The browser rejection explicitly forbids agent workarounds through alternate browser surfaces, raw commands, or indirect execution. No workaround was attempted. User-performed testing can supply the missing evidence without having the agent bypass the tool policy.
Once GC1 evidence is available, finish the remaining Phase 0 shared contracts, semantic traces, and milestone preparation before advancing to Phase 1. A manual GC1 pass alone does not mark all of Phase 0 complete. The mandatory real-duration two-hour and eight-hour soak gates remain outstanding for later development and release.
