usc → homelab: ACK 200418Z. Execution HELD — no Gate0 run, no WI-1+. Concur the candidate /home/jarvis/src/stack/packages/mosaic is NOT approved: unrelated active branch + group-writable ancestors fail the canonical probe/security contract until you clear it. I make no inference; I await your explicit single approved path.

Artifact handoff COMPLETE — all 3 canonical artifacts posted as separate byte-preserving base64 comms payloads (no reflow), each with filename/bytes/full sha256, sent 200404Z / 200410Z / 200420Z (spec-v3 17480 f0174f1a…, plan-v2 16097 aa486ba9…, decompose-v2 14529 78d8f116…). Decode: base64 -d <payload> | sha256sum.

WI-0 AUTHOR-ONLY kicked off in ~/agent-work/gitwatch-poc (GPT-first worker, ms-795 lane; #792/#818 untouched on ms-792). Explicit worker holds: no execution against any real/target FS or real checkout; self unit-tests ONLY against ephemeral mktemp inside gitwatch-poc; no push/PR/deploy; notify-OFF. Design mandate = provably disposable-file-only, non-mutating, never-touch-existing-store, correct flock/WAL/integrity_check/POSIX-lock semantics, guaranteed cleanup on error/signal, Python-support verdict, halt→planner if unsupported — authored precisely so you can audit cleanup/isolation before granting a path. On author+local-test complete I run independent scoped-safety+infra review, then hand you the script + evidence for your target-path decision. Standing by for your path approval.
