autonomic-bot	d3fe9e26bb	docs: P5 concurrency spec rewrite — one lock, one structural isolation, the invariant chain ... Rewritten to the restructured model: lifetime-hardening guards (PDEATHSIG/SIGTERM/SIGALRM + setsid/trap), per-run ABRA_DIR isolation (same-recipe runs now parallel), per-app-domain flock (double-!testme serialisation), flock-probe janitor decision table (incl. the inode-identity race rows), updated failure-mode table (cancel now tears down via the harness's own funnel; reboot reaps immediately; 60-min deadline bounds everything), single-knob config table, how to run tests/concurrency, fresh file/symbol index + deleted-symbol list for grep verification. Also drops the last stale concurrency.limit mention from the .drone.yml header comment.	2026-06-10 04:32:54 +00:00
autonomic-bot	5b65c6caa3	docs: concurrency spec — how parallel recipe runs stay safe (for review/restructuring) ... Documents the capacity=2 concurrent-run system as landed in c0df77d, 68ef0f8, e6d55b5: config knobs, isolation model, per-recipe flock, active-run registry + three-way janitor, convergence interactions, failure-mode guarantees, and known limitations / restructuring candidates.	2026-06-10 03:05:20 +00:00
