I read this as a fix-and-verify task - I’ll trace the disposable E2E and adapter at runtime, replace only the external model dependency with a deterministic loopback wire fixture under failing-first coverage, scrub diagnostics, then run every required gate and the literal full flow to its exact pass condition.


The environment confirms the live production gateway is separate and must remain untouched; the disposable harness is already isolated but still routes generation to Ollama. I’m now narrowing the exact wire seam and locating the prior raw-output diagnostic before writing the red contract test.


The focused test is RED at the intended boundary: the deterministic provider fixture does not exist, so the adapter cannot be exercised without the external model. I’m implementing that loopback OpenAI-compatible boundary now and removing the confirmed raw-output capture hook before integration.


Focused wire and harness contracts are GREEN (`18 passed`), Ruff is clean, the deterministic request is confirmed as real `POST /v1/chat/completions` with the unchanged 256-token strict schema, and the raw capture hook is gone. I’m entering full manual QA with the literal command and fresh target evidence now.


I read this as a critical-path continuation - the loopback provider is implemented, so I’ll read only the fresh disposable failure receipt, fix the first concrete harness/protocol mismatch, run the narrow gates, and repeat the literal E2E until `DISPOSABLE_E2E_PASS`.


I read this as a mandatory consolidation checkpoint - I’ll report the exact latest failure and cleanup state before deciding whether a single proven harness mismatch remains; I will not edit or attempt another approach during this checkpoint.


I read this as a lead-takeover checkpoint - I’m stopping edits because three delivery-boundary approaches failed.

- **Latest literal command:** exit `1`; stdout `DISPOSABLE_E2E_BLOCKED`
- **Exact error:** `DisposableHarnessError: timed out waiting for normal-restart polling`
- **Last completed lifecycle stage:** crash after known-message response, update ID `4`
- **First unmet observable:** replacement child never became polling-ready for the normal restart
- **Model provider:** not reached in this latest run (`requests: []`)
- **Cleanup:** all inspected failed runs reported every cleanup field `true`. Currently:
  - no disposable child process
  - no disposable profile/authority temp directory
  - Bot/model ports released
  - both fixture threads stopped

Files changed after the initial loopback provider test became GREEN:

- `scripts/dualcoach_v111_disposable_fixture.py`
- `scripts/dualcoach_v111_disposable_process.py`
- `scripts/dualcoach_v111_evidence.py`
- `scripts/dualcoach_v111_fake_telegram_engine.py`
- `scripts/run_dualcoach_v111_disposable_e2e.py`
- `tests/gateway/test_fake_telegram_bot_api.py`

The new loopback fixture and focused test also remain:

- `scripts/dualcoach_v111_loopback_model.py`
- `tests/gateway/test_dualcoach_loopback_model_provider.py`

Prior narrow gates: `19 passed`, Ruff clean, `py_compile` clean. Strict basedpyright exposed pre-existing runner typing errors.

No further approach attempted; lead takeover is required.
