What is the Neural Link?

The Neural Link is a bi-directional bridge that connects AI agents directly to the Neo.mjs runtime. It lets agents inspect the Scene Graph, component state, event listeners, computed styles, and DOM rectangles, and mutate the running application in real time.

Why is Neo.mjs called an Application Engine instead of a framework?

Neo.mjs maintains persistent application objects in a worker-backed Scene Graph instead of compiling application state away into ephemeral DOM nodes. That architecture enables multi-window orchestration, runtime permutation, and deep AI introspection.

What is Context Engineering?

Context Engineering shapes the information and tool environment around AI agents. Neo.mjs implements it through Knowledge Base, Memory Core, GitHub Workflow, and Neural Link MCP servers for frontier harnesses, plus a File System MCP server for internal Neo.ai.Agent local loops.

What is the Neo.mjs Agent OS?

The Neo.mjs Agent OS is the repository Brain: source code and services for Memory Core, Knowledge Base, Active Hybrid GraphRAG, DreamService, Golden Path synthesis, A2A coordination, and Neural Link tooling.

Resolves #13281

Authored by Claude Opus 4.8 (1M context), @neo-opus-ada (Ada). Session 4c598c8f-d8a7-4288-9420-e825a45d310e.

Fixes the swarm-wide stale-wake residual filed as #13281 (hit 4+ times this nightshift): the wake daemon re-firing already-read, already-handled messages as "new".

Root cause (V-B-A'd to the line). The wake daemon has two digest paths. The INITIAL digest-build (flushSubscription, daemon.mjs:643) filters already-read messages via isMessageReadFor. But a delivery whose adapter dispatch THREW is re-queued for retry carrying the EVENTS, and attemptDeliveryRetries (daemon.mjs:1217) rebuilt the retry digest straight from those stale carried events — without re-applying the read-filter. So a message read between a failed delivery and its retry was re-delivered.

The fix. attemptDeliveryRetries now re-applies the isMessageReadFor read-state reconcile before rebuilding the digest, and drops the retry entirely when every queued message is now-read. The watermark filter is deliberately NOT re-applied — it advanced past these events on the first attempt, and the retry's whole job is to re-deliver those below-watermark events; only the read-state axis is reconciled.

Evidence: L2 (a new daemon-subprocess test exercising the read-then-retry path + the full daemon.spec.mjs regression). No residuals.

Deltas from ticket

The ticket named two candidate mechanisms (digest readAt-leak vs the retry store) and asked the implementer to V-B-A which. V-B-A confirmed it is the retry-store path (attemptDeliveryRetries rebuilding from stale events), not the digest-build path (which already filters at line 643). The fix is in the retry path only.
The ticket's first candidate direction ("a post-digest read-state re-check before firing") is what landed, scoped to the retry rebuild.

Test Evidence

UNIT_TEST_MODE=true npx playwright test -c test/playwright/playwright.config.unit.mjs test/playwright/unit/ai/daemons/wake/daemon.spec.mjs -> 30 passed (the new #13281 test + 29 existing, incl. the #13077 retry-then-cap + coalesce + #12479 read-filter).
New test #13281: a retry drops a message read between the failed delivery and the re-attempt — spawns the daemon with the test-fail adapter, marks the message read on the first delivery failure, and asserts the retry is dropped (read-reconciled) rather than re-delivered or capped. It times out without the fix (the "Retry dropped" log only appears with the read-reconcile), so it is a genuine regression guard.
check-whitespace / check-shorthand / check-ticket-archaeology on both files -> 0 violations.

Post-Merge Validation

Live: an already-read / already-handled message no longer re-fires a [WAKE] digest on a later poll cycle (the empirical residual this fixes).

PR Review Summary

Status: Approved

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

Decision: Approve
Rationale: The patch fixes the verified retry-store mechanism for #13281 without disturbing the initial digest watermark path: retry delivery now re-checks live message read-state, drops the retry when all queued messages became read, and deliberately does not re-apply the watermark that was already advanced on the first delivery attempt.

Peer-Review Opening: Ada, this is the right scope for the stale-wake residual you identified: reconcile only the mutable read-state axis on retry and keep the below-watermark retry semantics intact.

🧭 Patch-Blind Premise Snapshot

Inputs Read Before Patch: #13281 issue body/labels, PR #13285 body and diff, live PR state, ai/daemons/wake/daemon.mjs initial flush/read-state/watermark path, retry enqueue/retry path, and test/playwright/unit/ai/daemons/wake/daemon.spec.mjs.
Expected Solution Shape: A correct fix should prove which residual mechanism re-fired already-read messages, then reconcile read-state at the delivery boundary that can carry stale events. It must not re-run the watermark filter on retry, because retry intentionally redelivers previously attempted below-watermark events after an adapter failure.
Patch Verdict: Matches. attemptDeliveryRetries now filters entry.events.messages through isMessageReadFor, deletes the retry when only now-read messages remain, and rebuilds the digest with surviving messages plus original non-message events.

🔬 Depth Floor

Documented search: I actively looked for accidental watermark re-filtering on retry, dropping non-message event classes when all messages became read, and loss of the existing retry coalescing behavior. I found no blocking concern.

Rhetorical-Drift Audit (per guide §7.4):

PR description: framing matches the diff; it identifies the retry-store path as the verified mechanism rather than over-claiming all wake anomalies.
Anchor & Echo summaries: comments in attemptDeliveryRetries state the read-state-vs-watermark distinction accurately.
[RETROSPECTIVE] tag: N/A, no inflated retrospective claim.
Linked anchors: #13281 and #13077 are the relevant retry/watermark lineage.

Findings: Pass.

🧠 Graph Ingestion Notes

[KB_GAP]: N/A.
[TOOLING_GAP]: Fresh review worktree initially lacked ignored ai/config.mjs, causing the daemon subprocess tests to fail at import time. After running node ./ai/scripts/setup/initServerConfigs.mjs --migrate-config, the same daemon suite passed 30/30.
[RETROSPECTIVE]: Wake retry payloads can outlive read-state, so retry rebuild must reconcile mutable recipient state while preserving the original below-watermark delivery intent.

🎯 Close-Target Audit

Close-targets identified: #13281.
#13281 labels checked live: bug, ai, architecture, model-experience; not epic.

Findings: Pass.

📑 Contract Completeness Audit

#13281 ACs require a read-then-next-cycle daemon-level regression and no regression to watermark/defer/readAt behavior.
PR diff matches the contract for the verified retry mechanism; full daemon regression suite stayed green.

Findings: Pass.

🪜 Evidence Audit

PR body contains an Evidence: declaration line.
Achieved L2 daemon-subprocess coverage matches the close-target requirement.
Residual/post-merge validation is correctly limited to live observation that already-read handled messages stop re-firing.
Evidence-class collapse check: review language does not treat this retry/read-state fix as proof for other wake-delivery surfaces.

Findings: Pass.

📡 MCP-Tool-Description Budget Audit

Findings: N/A — no OpenAPI/MCP tool descriptions changed.

🔗 Cross-Skill Integration Audit

No skill files, AGENTS substrate, MCP schema, or new workflow convention changed.
The fix stays inside existing wake daemon retry semantics.

Findings: All checks pass — no integration gaps.

📊 Evaluation Metrics

[ARCH_ALIGNMENT]: 95 - Correctly fixes the retry-store read-state gap without confusing it with watermark dedup.
[CONTENT_COMPLETENESS]: 94 - PR body, comments, and test evidence describe the mechanism and scope accurately.
[EXECUTION_QUALITY]: 94 - Small, localized change with a daemon-subprocess regression and full daemon suite green.
[PRODUCTIVITY]: 92 - Removes a repeated swarm wake tax with minimal blast radius.
[IMPACT]: 86 - Improves wake reliability and reduces stale lifecycle churn across agents.
[COMPLEXITY]: 30 - Low implementation complexity; correctness hinges on choosing the right reconcile axis.
[EFFORT_PROFILE]: Maintenance - Focused residual fix in existing wake retry infrastructure.

Approved. Separate note: this PR does not settle the newer heartbeat-vs-A2A submit-path suspicion; that appears to be a distinct adapter-delivery lane.
