Rocq log: 1RB0LD_1RC0RE_1LD0RE_1LA0LA_1RB1RF_1RB--- (line 388)

2026-10-10, formalization round 1 (kill stage)

Start: rocq/delta_check.v (the proof.md section 5 delta of kill #33's .v, sha256 37cb1802...2053; scratch compile already clean, rocq/delta_check.out).
Kill file = delta_check.v with only the header comment rewritten to house style: "Adapted from" line naming #33 and the busycoq mechanism (verify/SBCv6.v, Module TM21), the AI-assistance line, the "Checked: ... busycoq BB6 (commit 0940bb9) with Coq 8.20.1; Print Assumptions nonhalt: Closed under the global context" line. No repo-local paths in comments (grep for vendor/ machines/ tools/ rocq/ scripts/ reports/: none). Code below the header is byte-identical to delta_check.v. Rule-table comment block at the bottom kept.
Proved (all of it, no tactic changes from #33): window lemmas S1-S6, T1-T14 by es; digit lemmas and sweeps by ind/induction; chunks and M_spec / Mdrop_spec / O_spec by follow chains; INV closure (macro_step) verbatim; init: c0 -->* K [d1 1 9] 8 1 (687 steps, solve_init); nonhalt via multistep_nonhalt + progress_nonhalt_cond (P := INV), base closed by #33's tactic line.
tools/check_kill.sh: RESULT: PASS, exit 0 on the first run. sha256 6238e25c639d96b40bb55542a76c3d11972053ef3280d039b629a8bf9d7151bd, 673 lines, compile 9.2 s (native yes), coqchk -norec pass 1.8 s, 0 assumptions. Full output: rocq/check_kill.out.
Nothing failed this round.

Fresh human-readable tools/check_kill.sh run (no --json), started 19:23:25Z after waiting for another agent's check_kill to finish (one at a time): RESULT: PASS, exit 0, 17/17 checks, same sha256 6238e25c...51bd, compile 9.1 s (native yes), coqchk -norec pass 1.8 s, 0 assumptions, checked_at 19:23:38Z. Output: rocq/check_kill_fresh.out (= submission/check_kill.txt).
No tactics tried; nothing failed.
