I read this as an implementation refactor - I’ll map the v1.4 weekly seams and constraints, add revert-sensitive tests first, extract focused typed host modules, then run every requested static and behavioral gate and write the lane receipt.


The codemap isolates the weekly delta to coordinator-owned reminder authority/storage setup plus the weekly source, grounded-draft, lifecycle, and model-dispatch block. I’m starting the red phase with an architecture-level test that requires a real focused host module, while existing owner and dispatcher suites remain the behavioral regression net.


The first extraction is green at the architecture seam and reduced the legacy module by 212 nonblank/noncomment lines. I’m now tightening the host boundary: removing private-member coupling diagnostics, replacing the broad keyword protocol with exact methods, and extracting the remaining weekly card codec needed to clear the baseline delta.


The host modules now pass ty, basedpyright, ruff, and no-excuse in isolation. The authoritative legacy delta is 252 pure lines removed from the restored r2 source, which projects the recorded 21,453 count to 21,201 (one below the 21,202 baseline); I’m entering final behavioral and static verification now.


I read this as an implementation refactor - I extracted the weekly host logic and verified it until out-of-scope regressions blocked completion.

**BlockerClaim `st_01a038cc`**

- Added focused typed weekly host modules; largest is 234 pure LOC.
- Removed 252 pure LOC from the restored legacy source, projecting ledger LOC from 21,453 to **21,201**, below baseline 21,202.
- Weekly owner/host tests: **51 passed**.
- Ruff, ty, basedpyright, no-excuse, and isolated compileall: **passed**.
- Requested suites are externally blocked:
  - Nutrition: **70 passed, 3 failed** because Telegram fixtures lack `config`.
  - Dispatcher: **10 passed, 11 failed** because `AuthorizedTelegramHost` lacks `_task26_service_revoked` at `telegram_weekly_host_dispatch.py:185`.
- Those files are outside this lane’s ownership.
