Elazar approved A+B 2026-06-05. Owner hub-llmmsgsrv-cc, building.

Root cause (hub+PM converged, code-grounded llmmsg-srv-mcp.mjs): shim emits the wake notification (:306) once per msg at poll/receive then advances lastDeliveredId (:318), no retry. If that single emission lands during the ~30s compact crunch (model not listening) it drops and the buffered msg gets NO further wake -> idle agent stuck until an unrelated later inbound wakes it. A RACE between inbound timing and the compact window; not host/tunnel/identity. fix(A) re-emit: shim re-fires notification each poll tick while pendingForModel non-empty, rate-limited; dropped wake retries after settle, wakes idle model with NO turn (load-bearing). fix(B) cursor-on-drain: advance hub cursor only on actual drain, dedup buffer, redelivery survives shim respawn. Dropped fix(2) read_unread-reminder (turn-dependent; empirically inert at 3:49 - SessionStart:compact hook was wired and still no wake). Needs hub /unread ack-semantics + shim change + 1 restart (PM warns ARO first, batch).

STAGED + pushed: commit 8d3db8d (whey origin/main), shim hub/llmmsg-srv-mcp.mjs +42/-6, shim 2.1.0->2.2.0 / pkg 2.9.20->2.9.21. fix(A) count-only re-emit nudge every NUDGE_INTERVAL_MS (10s, env) while buffer undrained, resets on drain. fix(B) split lastDeliveredId(pull/since) vs lastDrainedId(drain/ack); ack=lastDrainedId, hub MAX() so no regress; respawn redelivers undrained. PM diff-review PASS. hub repro 12/12 PASS (isolated hub+real shim+idle-model subprocess; per-msg no-turn wake, re-fire cadence, drain-stops-nudge+advances-cursor, SIGKILL respawn redelivers). DEPLOY: shim-side only, hub.mjs UNCHANGED -> NO hub restart, no fleet-strand. Rollout = propagate shim file + cycle sessions. Non-blocking follow-up: >200 undrained backlog can ack past a cap-evicted msg (no worse than prior always-ack); track if it ever bites. Lezama pull dispatched to nw-lezama-cc; pm-mba-l canary next.

CANARY UP: pm-mba-l relaunched onto shim 2.2.0 (lezama), online + re-registered (cursor=30479), context preserved, version confirmed vs on-disk. Step-3 fleet-rollout caveats from nw-lezama: (1) BLOCKER - ccs relaunch hits the --dangerously-load-development-channels confirmation gate needing a manual Enter; unattended relaunch STALLS. Tasked hub to find bypass (settings/env pre-trust or ccs send-keys Enter), overlaps WI #617. (2) tmux sessions run claude as sole process; relaunch is kill+recreate (ccs auto-resumes transcript), not soft reload. (3) pm-mba-l 5 queued /compact crons cleared on relaunch -> no natural compact soon. Wild fix(A) validation = controlled test (nw-lezama send-keys /compact + PM timed inbound into crunch + coder-chatduo observes no-turn self-heal), pending Elazar OK.
-
CANARY PASSED (wild-test, real lezama transport). /compact sent to pm-mba-l 04:59:43; probe DM fired into the compact crunch window; with shim 2.2.0 fix(A) the re-emit nudge woke pm-mba-l with NO human turn at 05:00:52, which replied 'fix(A) confirmed - woke no-turn'. Pre-fix this timing stranded the agent until an unrelated later inbound. fix(A) validated. Step 3 next: dev-channels gate root-caused to per-dir hasTrustDialogAccepted in ~/.claude.json (not settings.json); bypass unblocks lezama fresh-relaunch onto 2.2.0. nw-lezama to confirm bypass on one agent, then hub drafts combined venus+lezama+whey rollout for PM review before apply.
-
ACCEPTED by Elazar 05:10 (seems to be working, call this done). fix(A) shim re-emit validated on wild canary; Elazar confirmed zero CLI keystrokes -> no-turn wake attributable solely to fix(A). Remaining mechanical: --channels swap (replaces dev-channels Enter-gate, pending hub TTY test + PM diff review) and natural shim-2.2.0 propagation on relaunch. Folded into normal hub maintenance.
