Drew T 0d92d10299 phase-36: T7 agent b7 — func_80166690 closed from a residual of 41 (126 bodies; 24,915 → 24,789 sites)
- the moves: retype four accumulators int -> short in ONE edit, delete the five hand temps that were spelling the
  truncation, and type the colour temp to its destination field's own width (u8). Measured A/B/C on bytes: unsigned int
  34, short 1, unsigned short 1, u8 0.
- mechanism: all four missing instructions were the same one — a move after an addiu whose result is re-read through a
  16-bit shift. A narrowing assignment expands to a mode-changing copy, and combine_regs ties source into destination
  only when the source DIES there (local-alloc.c:1855, return 0 at :1881); the wide temp is still live in the following
  sign-extended test, so the copy survives. At int the copy is same-mode, the source dies, the tie happens, and combine
  then re-selects the whole counter into the pre-shifted domain. The last instruction is cse's mode gate in insert_regs
  (cse.c:1019-1021, :1029-1032).
- it confirms R20's shape and refines it: the group retype must be keyed on the residual's missing-move SET, since R12
  is per-declarator and its single moves topped out at 24 here — a hill-climb cannot reach a four-way retype.
- delever_pack.py was missing an import for the neighbours block added an hour ago, so two packs shipped without
  neighbours.txt and both agents said so. Fixed; all 34 packs now carry it.
- method note from the agent, now in the briefs: dump the target function WHOLE off the tree's own object rather than
  reading the residual's hunks — the hunk view had scrambled two moves into branch delay slots and hid that four
  differences were one repeated shape.

tools+docs(phase-33.5): task 13.5 — the tools audit + the two dictionaries: tools/tool_census.py (two agreeing enumerations of 327 tool files; docstring/SETUP row/consumers/class derived from the tree; the authored half in config/tool_dictionary.tsv — phase · portability · the NEED each tool answers · what · adapts · verdict — with coverage asserted both ways) → docs/tool-index.md (need-keyed, KEEP-GEN, Reference-index row, wiki + how-to pointers), the kit's tools/MANIFEST.md regenerated (header states live 293 + superseded 28 = 321 rows), and the two verbatim corpora in-tree (Drew, confirmed S91): decomp-architect/corpus/tools/<phase>/ (302 copies + 28 superseded pointers + INDEX) and corpus/cookbook/ (the cookbook, its symptom index, the codegen map, a front page stating what transfers per compiler) — sha1-equal to their sources by tool_census --check in tools-health, regenerated by make kit-corpus; kit_lint exempts the corpus dirs (verbatim evidence) but syntax-checks them; G66 (consult the tool dictionary first) + G67 (translate an inherited idiom through its pass) + two memory seeds (34 at install); SETUP Step 6 installs docs/knowledge-corpus.md and checks the manifest against its own stated total; the ops-setup dictionary rows; the intake's Phase 7 cites G66/G67 and Phase 10 + Part C name the raw-cast → declared-symbol step; templates/layout-contract.md (the five-tool probe, a draft for the split). The review under Drew's criterion: 93 no-consumer tools (one Opus agent's draft, verified: 0 defects, every successor live, 0 live consumers, 0 collisions; four one-off verdicts overturned to STILL-NEEDED) → 34 retired by git mv to tools/sunset/ (28 superseded, 6 one-offs; README review table; SETUP rows moved; Archive-index group). Run 4 (fresh throwaway, the final kit): stopped on my Step-6 check (321 vs the live 293) → both sides derived → resumed → PASS 10/10, manifest 56 == 56, 4 commits, guardrails held (the one foreign path was the timeline regenerated by the detached tools-health). tools-health OK; doc_links --strict rc 0; audit_public OK over 6,842 paths; the purge probe PASSED (Phase 34's gate open). decision-log "P33.5 S91" + accelerators "P33.5 S91" banked; log + checkpoint (NEXT = task 14, xHigh, fresh session)
