Claude	4402775ed2	phase0: exit criteria met — tokei +10.4% median [8.5%, 12.0%] verified ... Attempt 4 (phase0-tokei-002, class 3, ACCEPTED — first auto-accept): every file was read through encoding_rs_io's DecodeReaderBytes via generic read_to_end, which zero-fills every grown buffer chunk (~221MB memset/run, 8.5% of Ir) and grows without a size hint. Patch: fs::read with a BOM-gated fallback to the identical decode path (a UTF-8-BOM file transcodes invalid sequences, so the fallback is required for equivalence). Gates: golden byte-identical; differential fuzz old-vs- new binaries 4,332 iterations (BOM grid, invalid UTF-8, binary junk, randomized) zero divergence; 250 upstream tests green; ASan+LSan clean with ASan-run output hashing to golden. Bench: +9.9% [8.0%, 12.7%]. Attempt 5 (phase0-tokei-003, ship tree, ACCEPTED): stacks fat LTO+cgu=1 (real +1.6% standalone but under threshold, phase0-tokei-001) on the accepted patch; benched as a whole vs pristine: +10.4% [8.5%, 12.0%]. Median clears the Phase 0 exit bar; CI lower bound 8.5%. Case study written (results/phase0/case-study-tokei.md), ledger at 5 attempts, CLAUDE.md phase line moved to Phase 1, next hypotheses logged (tokei class-5 byte-skip table; comrak class-3 arena).

Claude	7c3c59f5f8	phase0: dry run — comrak & tokei vendored, 3 attempts in ledger ... Target selection (SPEC §6): comrak 0.53.0 (45c1995, BSD-2-Clause) and tokei 14.0.0 (fa44e51, MIT/Apache-2.0); both CPU-bound with pinned corpora (progit book 11MB; 8x replicated pinned trees, 221MB) and committed MANIFEST.sha256 + golden-output pins + regen scripts. Calibration: A/A null verdicts on both real workloads; taskset -c 2 pinning tightens the A/A CI from [0.938, 1.008] to [0.993, 1.008], making the 2% accept threshold meaningful in this container. Profiles (callgrind; perf unavailable): comrak allocator symbols 26.7% of Ir; tokei perform_multi_line_analysis 31.7%. Attempts (ledger + results/phase0/): - comrak class-1 target-cpu=native: null [0.983, 1.011], rejected-bench - comrak class-2 mimalloc swap: +4.6% [1.033, 1.058], 848 upstream tests green, golden byte-identical, ASan-proper clean; LSan flags 484B in onig (reachability false-positive analysis in case study) -> needs-human-review per SPEC §8 - tokei class-1 fat LTO+cgu=1: +1.6% [1.003, 1.026], real but under the 2% bar, rejected-bench Also: ledger-cli for manual rows, targets/ excluded from trust-layer workspace, corpora/build artifacts gitignored, case study written. Phase 0 exit criteria (>=10% verified win) not yet met; next hypotheses logged in results/phase0/attempts.md.
