I read this as a strict-typing repair across the listed Python fixtures/tests - I’ll load the Python rules, inspect only those files and project config, then patch and verify with basedpyright, tests, Ruff, compilation, and the literal E2E.


The initial strict run found 64 errors and 190 warnings, concentrated in dynamic monkeypatches and untyped JSON/argparse boundaries; the remaining files have only fixable unused-result/override diagnostics. I’m preserving runtime paths while replacing those boundaries with typed adapters, Protocols, and explicit narrowing.


I read this as an immediate checkpoint - I’ll run the exact strict basedpyright command now, group remaining errors by file, and stop further edits if more than 20 remain.


Strict basedpyright checkpoint:

- **27 errors**, **66 warnings**
- `tests/gateway/test_fake_telegram_bot_api.py`: **25**
- `scripts/dualcoach_v111_disposable_process.py`: **1**
- `scripts/run_dualcoach_v111_disposable_e2e.py`: **1**

Per instruction, I stopped further edits because errors exceed 20.


I read this as a read-only runtime regression postmortem - I’ll inspect the recorded edits/transcript and the current child-process/fake Telegram paths, then identify the exact behavioral delta and minimal restoration without running the E2E or editing files.


Postmortem finding: **none of my edits changed or removed `Application.process_update` wrapping.**

- The only relevant edit was `scripts/dualcoach_v111_disposable_process.py::_install_fault`.
- I changed fault probes from direct class assignment to equivalent `setattr` calls:
  - `TelegramPollingReceiptGate.completed`
  - `GatewayOnboardingPublicationOutbox.record_receipt`
  - `NutritionCoachingCoordinator.record_delivery_transport_receipt`
- No edit referenced `Application` or `process_update`; transcript search confirms this.
- The fake Telegram files never monkeypatched `Application.process_update`.

The failing code is in unchanged production code:

```python
gateway/platforms/telegram.py::_install_task26_update_processing_authority
setattr(application, "process_update", process_update_with_authority)
```

That function is unchanged relative to `HEAD`. The current worktree also contains unrelated uncommitted production changes, but none alter this setter.

Prior intended behavior: PTB’s `Application.process_update` was expected to be writable so the authority wrapper could be installed during adapter startup.

Smallest restoration: **restore the pre-lane runtime compatibility seam or production PTB-compatible wrapping mechanism; reverting my listed-file typing edits will not fix this failure.** No edits were made and no full E2E was run.
