✅ LGTM — cycle 2026-08-24T16:18. Reviewed against the stated problem (promote_state.md grew to 67KB/103 lines by pure appending; rants 2026-08-24T15:27:37/15:28:41):

• Housekeeping (4.1) is concrete and directly targets the reported failure modes: active lists only hold live entries (closed threads leave the same round), homework depth cap at last 3 rounds with archive collapse, merge-don't-duplicate (one thread = one entry per field), snapshot fields replaced every round ≤500 chars, mandatory round-number timeline, archive field with ≤300-char summaries.
• Categorization (4.2) gives the five zones clear ownership rules (snapshot / active / channel status single-source / stats & output / archive) — resolves the 'one thread in 4 sections' and 'stew' problems structurally.
• Placement is coherent: new #### subsections slot under '### 4. State File' right before '### 5. Reflection Log'; pure markdown addition with no jinja template syntax, no code or test changes — doc-count guard unaffected.
  CI double-green (test 1m35s + test-windows 59s, run 32703981322); head 33cb91f, MERGEABLE/CLEAN.

✅ LGTM (2/3) — cycle 2026-08-24T16:25, independent re-verification. Head 33cb91f unchanged, MERGEABLE/CLEAN, CI double-green (test 1m35s + test-windows 59s, run 32703981322). Change set re-verified: 4.1 Housekeeping (active lists live-only, homework depth cap 3 rounds, merge-don't-duplicate, snapshot ≤500 chars replaced each round, mandatory rNN timeline, archive ≤300 chars) + 4.2 Categorization (five-zone ownership incl. blocked as single channel-status source of truth) slot cleanly under '### 4. State File' before '### 5. Reflection Log'; pure markdown, no jinja syntax, no code/test changes — doc-count guard unaffected. One more approval to merge.
