docs(progress): sync Phase 1 replan status

[DeliciousBuding]

Summary

• Syncs docs/progress/MASTER.md after test(e2e): reuse data-mode boundary helper #397 merged and [T1.3] Reuse data-mode boundary helper in acceptance gates #380 was manually closed.
• Records the Phase 1 adaptive replan threshold before [T1.4] Document evidence bundle without rule duplication #381.
• Keeps [T1.4] Document evidence bundle without rule duplication #381 narrowed to docs-only closure instead of broadening the evidence work.

📝 Walkthrough

Walkthrough

docs/progress/MASTER.md is updated to mark T1.3 as closed via #397, advance the Phase 1 checklist from 2/4 to 3/4, reframe T1.4 as requiring an adaptive replan, redirect current status and next steps to keep #381 as a narrow docs-only task, and add a session log entry for the adaptive replan sync.

Changes

Phase 1 progress documentation

Layer / File(s)	Summary
Milestone table, checklist, and current status docs/progress/MASTER.md	T1.3 status changed to "closed via #397"; T1.4 marked "open; adaptive replan required"; checklist fraction incremented to 3/4; current status and blockers rewritten around drift_score=2 replan threshold with instruction to keep #381 docs-only.
Next steps and session log docs/progress/MASTER.md	Next steps rewritten to scope #381 as narrow docs-only and gate Phase 1 continuation on accepting the replan note; session log gains an entry recording #380 merged via #397 and #381 scope constraint.

Poem

🐇 Hippity-hop, the milestone's crossed!
T1.3 is closed, no progress lost.
The replan note says "docs-only, please,"
drift_score of two brings the work to ease.
On to T1.4 with a careful hop—
Phase 1 marches on, never to stop! 🌟
