box/fleet/tasks/done/195-dmlog-parse-share.md.muse--runtime--coordinator



Completed 2026-10-09T05:33:53Z via box tasks done:
Prod fix, 2 parts. (1) super-cli cmd_dm_log: newest-first early-stop parse (was full 37k-line parse + [-n:]); 9-case equivalence incl filters + n=0/-5 quirks, all identical; per-call parse 0.14s->0.01s. (2) box-ctl act_dm_log: super-cli SUBPROCESS -> lazy in-proc dispatch (same JSON shape + fail path). NOTE on prescription: literal parse-sharing across the 2 calls is impossible (each ran in its own super-cli process); in-proc + O(N) parse dissolves it - each dm-log now ~15ms total vs 350ms. Gates: 95 passed (box_dev 33, box_read 16, followup+loop_health 46); tests_run pair 1.4s->0.66s. Peer super-cli hunks intact; box-ctl was clean. OBSERVED follow-up (untouched, out of path): _policy_scan json-parses every line TWICE. Uncommitted.
