I read this as a focused TypeScript/Python typing fix - I’ll inspect the mandated Python guidance and the six in-scope files, then patch only strict narrowing issues and run every requested gate.


The failures are confined to boundary narrowing: one protocol field is being re-inferred through `getattr`, one nested JSON payload is accessed before its narrowed value is retained, and seal artifacts are invariant `dict` values. I’ll fix these with the existing protocol contract, a local payload narrowing loop, recursive `Mapping` JSON types, and a runtime-proven `TypeGuard` for semantic artifact seals.


Both exact basedpyright gates are now green. The patch preserves runtime validation and output shape; next I’m running the focused tests and all requested static/runtime hygiene checks in parallel.


The requested no-excuse audit found one size violation in the touched seal script, caused by the first readable narrowing form adding lines; all functional checks passed. I’m tightening only those equivalent expressions so the audit is clean without adding a suppression or changing behavior.


The tightened form now passes the no-excuse audit with no suppressions. I’m repeating both exact basedpyright commands plus the final focused Ruff, compilation, test, audit, and scope checks against the finished tree.


I read this as strict typing cleanup only - completed the minimal narrowing fixes within scope.

Changed:
- `gateway/platforms/telegram_production_preflight.py:93`
- `scripts/compare_dualcoach_v111_seals.py:14,38,106-110,216,298-305`
- `scripts/migrate_dualcoach_v111_profile.py:29-38,50,191-203`

Proof:
- Both exact basedpyright commands: **0 errors**
- Focused tests: **35 passed**
- Ruff: **passed**
- `py_compile`: **passed**
- No-excuse audit: **no violations**
- No commits; tests and planner were not modified.
- Pure LOC remains within limits: compare script **248**, migration script **242**.

Review: responsibilities remain focused, JSON boundaries are runtime-narrowed, no escape hatches/suppressions/logging changes were added, and existing exhaustive matching and tests remain intact.
