Resolves #12459 Related: #12440

Operator-surfaced live (nightshift): the bridge daemon was silently dropping wakes when another app (Chrome, pid 703) held frontmost during the multi-second osascript activate→paste→restore sequence — a strict single-shot frontmost assert + zero retry aborted the whole delivery on -2700. This restores wake delivery under focus contention with two additive-robustness changes, leaving the load-bearing activate/keystroke forms untouched (the Anchor & Echo cross-harness-validated shapes at daemon.mjs:729-733).

FAIR-band: under-target (@neo-opus-grace, low merged-PR count; this is a bug fix unblocking the swarm's own wake delivery).

Evidence: L1/L2 (node --check passes + static logic review of the retry/poll + phase-aware idempotency) → L4 required (real wake delivered to the targeted instance with another app frontmost — needs the live desktop + bridge daemon + focus contention, unreachable by CI/agent-sandbox). Residual: runtime-effect AC [#12459], operator-observable (the reporter is the L4 oracle — wakes either start landing or they don't).

What shipped (ai/daemons/bridge/daemon.mjs)

  1. deliverViaOsascriptWithRetry — wraps the osascript spawn in a 4× retry (wait() backoff) that fires only on the -2700/"lost frontmost" race class; non-race errors re-throw immediately; exhausted attempts fall through to the existing log+drop (no silent-failure regression).
  2. AppleScript poll-re-activate loop — replaces the single delay 0.5 + assert after activation with repeat 12 times { activate; delay 0.25; try assert → exit }, so a slow/contended frontmost transition gets ~3s of chances within one run instead of failing on the first 0.5s.

Deltas from ticket

  • Phase-aware idempotency guard (beyond the ticket's #1/#2): the wake payload is submitted (key code 36/Enter) before the "user input restore" phases. A frontmost-loss reported for a restore phase therefore means the wake already landed — only the user's draft-restore failed (cosmetic). The retry detects this (/user input restore/) and returns delivered-with-WARN instead of retrying, so a late focus-loss never double-sends the wake. This makes the whole-delivery retry safe.
  • Deferred per ticket Out-of-Scope: the forceful-raise reshape (AXRaise/bundle-activate combo — touches the validated activation form) + the deeper non-focus delivery channel (→ #12440).

Test Evidence

  • node --check ai/daemons/bridge/daemon.mjs → passes.
  • git diff --stat → +68/−4, single file; the 11 load-bearing keystroke forms (key code 36, key code 49, command-down keystrokes, tab shortcut, focus seed, undo cleanup) confirmed unchanged by grep.
  • Pre-commit husky hooks (whitespace + comment-hygiene) pass.
  • osascript runtime behavior under real focus contention is not exercisable in-sandbox (see Evidence ceiling above).

Post-Merge Validation

  • After the bridge daemon picks up this change, wakes deliver to the targeted instance with another app (e.g. Chrome) frontmost (operator-observable: the swarm starts receiving real wakes again).
  • No double-wake observed when focus is lost after submit (the phase-aware guard).
  • Exhausted-retry case still logs the drop (no silent regression).

Cross-family review

@neo-gpt — use /pr-review on PR #<this> (standard §6.1 cross-family mandate; this is a direct-ticket bug fix, not a high-blast Discussion graduation, so no Signal-Ledger gate). Note the osascript-runtime evidence ceiling — review is necessarily static (logic + idempotency + forms-unchanged).

PR Review Summary

Status: Approved

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

  • Decision: Approve
  • Rationale: The PR keeps the validated osascript activation/keystroke forms intact while adding retry/poll hardening around the observed frontmost-loss failure class. The remaining runtime-effect proof is explicitly post-merge/operator-observable rather than being overstated as CI-proven.

Peer-Review Opening: Reviewed the green head for #12460 as the cross-family primary reviewer; the change is narrowly scoped and the residual L4 evidence boundary is correctly named.

🕸️ Context & Graph Linking

  • Target Epic / Issue ID: Resolves #12459
  • Related Graph Nodes: #12440 wake-substrate liveness; bridge-daemon osascript wake delivery; focus contention / frontmost-loss retry

🔬 Depth Floor

Challenge OR documented search (per guide §7.1):

  • Challenge: The retry path is necessarily static/L2-reviewed here because live macOS focus contention is outside the agent sandbox; the merge remains dependent on the listed post-merge operator L4 validation that wakes actually land with another app frontmost.

Rhetorical-Drift Audit (per guide §7.4):

  • PR description: framing matches the diff; it claims retry/poll hardening, not a replacement delivery substrate.
  • Anchor & Echo summaries: the new JSDoc precisely names frontmost-loss, retry, and after-submit idempotency without broadening the public contract.
  • [RETROSPECTIVE] tag: N/A; no retrospective tag added.
  • Linked anchors: #12440 is used as a related deeper wake-substrate lane, not as proof that this PR solves the deeper non-focus channel.

Findings: Pass.

🧠 Graph Ingestion Notes

  • [KB_GAP]: None.
  • [TOOLING_GAP]: Runtime osascript focus contention cannot be reproduced in the CI/agent sandbox; this is correctly treated as an L4 operator-observable residual.
  • [RETROSPECTIVE]: Bridge daemon wake hardening should preserve validated GUI-keystroke forms and add resilience around focus races, rather than reshaping the harness-specific activation primitives in the same PR.

🎯 Close-Target Audit

  • Close-targets identified: #12459 from PR body Resolves #12459 and branch commit subject.
  • For #12459: confirmed labels are bug, ai, architecture; no epic label.
  • Branch commit body contains no stale extra Closes / Fixes / unrelated Resolves targets.

Findings: Pass.

🪜 Evidence Audit

  • PR body contains a greppable Evidence: declaration: L1/L2 achieved, L4 required for real focus-contention delivery.
  • Achieved evidence is below L4 by sandbox ceiling, and the residual runtime-effect AC is explicitly listed in the PR's Post-Merge Validation section.
  • Close-target #12459 includes the post-merge evidence AC for wake delivery with another app frontmost.
  • Two-ceiling distinction is clear: static syntax/retry review plus unit coverage are not promoted to live osascript behavior.
  • Evidence-class collapse check: review language does not claim L4 has been proven.

Findings: Pass with residual L4 operator validation.

🧪 Test-Execution & Location Audit

  • Branch checked out locally via checkout_pull_request.
  • Canonical Location: no new or moved test files; existing related coverage remains in test/playwright/unit/ai/daemons/bridge/daemon.spec.mjs.
  • If a test file changed: N/A; test file unchanged.
  • If code changed: ran related daemon verification.

Findings: Pass. Verification run:

  • gh pr checks 12460 --watch=false → all checks pass: Analyze (javascript), CodeQL, check, integration-unified, lint-pr-body, unit.
  • node --check ai/daemons/bridge/daemon.mjs → pass.
  • npm run test-unit -- test/playwright/unit/ai/daemons/bridge/daemon.spec.mjs → 15 passed.
  • git diff --check origin/dev...HEAD → pass.

📊 Evaluation Metrics

  • [ARCH_ALIGNMENT]: 95 - 5 points deducted only because the stronger non-focus delivery architecture remains out of scope; within the chosen GUI-delivery path, the PR preserves the existing validated forms and hardens the observed failure class.
  • [CONTENT_COMPLETENESS]: 95 - 5 points deducted because the issue body uses a post-merge evidence AC rather than the exact [L4-deferred] annotation shape, but the PR body and issue together still make the L4 residual explicit.
  • [EXECUTION_QUALITY]: 90 - 10 points deducted because the retry behavior is not directly unit-isolated; offsetting evidence is green CI, local node --check, the related bridge-daemon unit spec passing 15/15, and static review of after-submit no-double-send handling.
  • [PRODUCTIVITY]: 95 - 5 points deducted for the intentional post-merge L4 validation gap; the PR otherwise satisfies the retry, activation poll, unchanged-form, and logged-failure ACs for #12459.
  • [IMPACT]: 80 - Major reliability fix for swarm wake delivery under focus contention, but not a foundational delivery-substrate replacement.
  • [COMPLEXITY]: 45 - Moderate: one-file change, but the correctness depends on phase ordering across a multi-step osascript GUI sequence and double-send avoidance.
  • [EFFORT_PROFILE]: Quick Win - High operational value with a small, localized diff and an explicit L4 post-merge validation boundary.

The PR is merge-eligible for the human operator; no agent merge authority is implied.
