Drew T 9d78fc4085 phase-36: T7 agent b3 — func_8016CBC0 closed from a residual of 55 (128 bodies), and its move toolified as R20
- the move: narrow every local in the counter's def-use chain together — the counter, its +/-1 temp and the copy-back —
  and do it for BOTH chains at once. Four instructions were MISSING, not miscoloured, three of them the moves the $0 pin
  was faking. insert_regs (cse.c:1029-1032, early bail :1018-1020) puts two pseudos in one equivalence class only when
  their MODES match, so an all-int copy-back is collapsed and swept, while the narrowed one is a truncation: no
  equivalence, the wide temp stays live and reaches reload as the move the target has. The fourth instruction is
  strength_reduce minting a shift giv from a wide counter whose every use is a cast; a HImode pseudo cannot be that giv.
  delever --propagate: 127 of 127 sibling(s) banked, 0 refused. 26,202 -> the census below.

- R20 narrow_chains: the agent PROVED the joint form is necessary, and the generator reproduces it. Single declarations
  scored 45/72/51/24, each chain alone 43, both chains together 0 — every intermediate worse than the search's own best
  of 11, so a beam over R12's one-declaration width moves cannot reach the answer from either side. Seven runs and 4,811
  compiles stalled at 11; R20 offers six candidates and the right one is a single compile.
- known-true check: run on b3's pre-bank text, R20's joint signed candidate scores 0 (MATCH) and its single-chain
  candidates score 43 and 51 — the agent's own hand-measured numbers, reproduced by the tool.
- chains are built conservatively from the body's text (two locals linked when one is assigned from the other, through a
  cast or a +/- constant), and only whole components are offered, so the partial narrowings the measurement showed are
  always worse are never generated. Selftest: the chain is found whole, an unlinked local is not pulled in, and a body
  with no linked pair offers nothing.

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)
