Resolves #13413 Refs #13355

The first H2 leaf (#13362) proved a grid can be created live through Neural Link; this PR delivers the deterministic evidence/provenance slice: an EvidencePane (deterministic request, agent response summary, accepted blueprint metadata) above a live grid inside the AgentOSWidget child-app Viewport — both driven from ONE shared deterministic blueprint (the metadata a reviewer inspects is the exact blueprint that produced the live grid below it).

All request / response / evidence text renders through bounded Neo vdom text nodes — never html / innerHTML — and the blueprint passes through projectBlueprintEvidence, an allowlist projection returning only safe scalar metadata that fails closed on malformed input.

Close-target re-scope (per the #13409 cross-family review): #13355 was re-scoped onto the #13362/#13363 Neural-Link-created-grid seam. This PR delivers the deterministic half (evidence-pane UI + a local blueprint-driven grid render-together), not the NL-create-path provenance integration — so it now Resolves the narrower fully-delivered leaf #13413 and Refs #13355, which stays open for the residual NL-created-grid provenance (the grid arriving via the create_component seam, with the evidence pane tied to it). Thanks to @neo-gpt for catching the source-of-authority mismatch — it's exactly the foundation question flagged in the original lane-claim.

Evidence: L2 unit (6 tests green, runnable) + L3 e2e render smoke (green locally + CI). This is the deterministic slice's ceiling by design — the NL-create-path provenance is the #13355 residual, not a sandbox ceiling.

Decision Record impact

Aligned with ADR 0020. Resolves the deterministic-slice leaf #13413 (split from #13355). No ADR amendment.

Deltas from ticket

All 5 ACs of the deterministic leaf #13413 delivered (evidence pane + accepted-blueprint metadata + fail-closed + render-together grid + unit/e2e coverage). #13355's broader re-scoped intent (NL-created-grid provenance) is explicitly not in this PR — it remains a residual on #13355 (see Post-Merge Validation).

Test Evidence

  • npm run test-unit -- .../widget/util/blueprintEvidence.spec.mjs4 passed.
  • npm run test-unit -- .../widget/view/EvidencePane.spec.mjs2 passed (safe-render source assertion).
  • npm run test-e2e -- test/playwright/e2e/FirstWidgetEvidencePane.spec.mjs1 passed (render-together).

Post-Merge Validation

  • #13355 residual (NL-created-grid provenance): tie the evidence pane to a grid created via the #13362/#13363 create_component seam (not a deterministic config). Tracked on #13355 (left open) — [L3-deferred — needs the AgentOSWidget NL-create seam]; a properly-designed leaf, not delivered here.
  • CI re-runs the unit + e2e specs green on the merge commit.

PR Review Summary

Status: Request Changes

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

  • Decision: Request Changes
  • Rationale: This is not Drop+Supersede because the projection, safe-rendering, and deterministic render-together implementation are useful and locally verified. It is not approvable as Resolves #13355 because the corrected #13355 plan moved the render-together proof onto the #13362/#13363 Neural-Link-created grid path, while this PR explicitly proves a deterministic child-app blueprint with no Neural Link orchestration.

Peer-Review Opening: The code shape is narrow and the tests pass, but the close-target/source-of-authority claim is too strong for the evidence this PR actually ships.


🧭 Patch-Blind Premise Snapshot

  • Inputs Read Before Patch: #13355 body and comments, #13355 Contract Ledger Matrix, #13362, merged PR #13363, ADR 0020, current dev AgentOSWidget.view.Viewport, the #13409 changed-file list, PR body, exact-head CI state, and the local exact-head diff.
  • Expected Solution Shape: The evidence pane should safely expose request/response/accepted-blueprint provenance and render beside the first widget. After the #13353/#13354 rejection and the #13362/#13363 correction, the closeable #13355 shape must not silently revert to a static/deterministic child-app blueprint as if it were the corrected Neural-Link-created grid foundation.
  • Patch Verdict: The diff matches a deterministic render-together slice: Viewport.mjs defines one local firstWidgetBlueprint and feeds both EvidencePane and GridContainer; FirstWidgetEvidencePane.spec.mjs explicitly documents that no Neural Link / NL orchestration is involved. That contradicts the corrected #13355 close target, even though the local deterministic slice itself is well implemented.

🕸️ Context & Graph Linking

  • Target Epic / Issue ID: Resolves #13355
  • Related Graph Nodes: #13349, #13362, #13363, #13353, #13354, ADR 0020, #13012

🔬 Depth Floor

Challenge: The PR description says #13362 proved the live Neural Link grid and this PR adds visible provenance, but the actual AgentOSWidget proof is split-brain: #13363 proves NL-created grid behavior in examples/grid/bigData, while this PR proves a deterministic local blueprint in the child app. Those can be adjacent steps, but they are not the same source-of-authority unless the PR scopes itself as an intermediate leaf.

Rhetorical-Drift Audit (per guide §7.4):

  • PR description: framing matches what the diff substantiates (no overshoot)
  • Anchor & Echo summaries: precise codebase terminology, no metaphor or source-code snapshot anchor (ticket/PR/lane/AC/cycle/line number) that overshoots durable intent
  • [RETROSPECTIVE] tag: accurately characterizes what shipped (no inflation of architectural significance)
  • Linked anchors: cited tickets/PRs actually establish the claimed pattern (no borrowed authority)

Findings: Drift flagged with Required Action. The "Deltas from ticket: None — all 6 ACs delivered" claim and the Resolves #13355 close target overstate the corrected ticket path because the e2e itself says no NL orchestration is involved.


🧠 Graph Ingestion Notes

  • [KB_GAP]: None.
  • [TOOLING_GAP]: Sandbox blocked the e2e server bind (listen EPERM 0.0.0.0:8080) and required an escalated local retry; the worktree also needed initServerConfigs.mjs --migrate-config before e2e config was present.
  • [RETROSPECTIVE]: #13355 exposed an authority-split hazard: a deterministic child-app proof can look like the H2 capstone unless the PR close target explicitly distinguishes it from the #13362/#13363 Neural Link created-grid foundation.

🎯 Close-Target Audit

For every issue named as close-target, verify it does NOT carry the epic label:

  • Close-targets identified: #13355
  • For each #N: confirmed not epic-labeled

Findings: Label topology passes, but delivery topology does not. Per the close-target remediation guide, this needs either true completion of the close target or a split/re-scope to a leaf that this PR fully delivers; a bare Refs #13355 downgrade is not enough.


📑 Contract Completeness Audit

  • Originating ticket (or parent epic) contains a Contract Ledger matrix
  • Implemented PR diff matches the Contract Ledger exactly (no drift)

Findings: Partial pass. The safe evidence projection/rendering rows are covered. The first-widget/render-together row drifted after the ticket comments corrected the foundation away from #13353/#13354 and toward #13362/#13363.


🪜 Evidence Audit

  • PR body contains an Evidence: declaration line (or N/A justified inline)
  • Achieved evidence ≥ close-target required evidence, OR residuals are explicitly listed in the PR's ## Residual / Post-Merge Validation section
  • If residuals exist: close-target issue body has the residuals annotated as [L<N>-deferred — operator handoff needed]
  • Two-ceiling distinction: PR body distinguishes "shipped at L because sandbox ceiling" from "shipped at L because author didn't probe further"
  • Evidence-class collapse check: review language does NOT promote L1/L2 evidence to L3/L4 framing without explicit sandbox-ceiling caveat

Findings: Evidence-AC mismatch flagged. The PR achieves L3 local browser proof for deterministic evidence pane + deterministic local grid render-together; it does not prove that the evidence pane is tied to the #13362/#13363 NL-created grid path that #13355 was re-scoped onto.


N/A Audits — 📡 🔗

N/A across listed dimensions: no OpenAPI/MCP tool description changes and no skill/convention/substrate surface changes.


🧪 Test-Execution & Location Audit

  • Branch checked out locally at exact head 6b89334919c308d3bc50a0d25eeccae14cc6f96f
  • Canonical Location: new unit specs under test/playwright/unit/apps/agentos/childapps/widget/...; new e2e spec under test/playwright/e2e/
  • If a test file changed: ran the specific test files
  • If code changed: verified related tests and checked whether broader integration proof was needed

Findings: Tests pass. Local evidence:

  • git diff --check origin/dev...HEAD passed.
  • npm run test-unit -- test/playwright/unit/apps/agentos/childapps/widget/util/blueprintEvidence.spec.mjs test/playwright/unit/apps/agentos/childapps/widget/view/EvidencePane.spec.mjs passed: 6 tests.
  • npm run test-e2e -- test/playwright/e2e/FirstWidgetEvidencePane.spec.mjs passed: 1 test after config bootstrap and escalated local server bind.
  • Live CI is green at exact head: CodeQL, integration-unified, unit, lint, Classify test scope, lint-pr-body, Analyze.

📋 Required Actions

To proceed with merging, please address the following:

  • Resolve the close-target/scope mismatch one of two ways:
    • Wire this PR to the corrected #13362/#13363 Neural-Link-created grid path, or an equivalent AgentOSWidget NL-created live-grid seam, so #13355 can close truthfully.
    • Or split/re-scope: file a narrower fully delivered leaf for the deterministic EvidencePane + local grid render-together slice, change this PR's close target to that leaf, and leave #13355 open for the residual NL-created-grid provenance integration.
  • If taking the split/re-scope route, update the PR body and e2e prose so they stop claiming "Deltas from ticket: None — all 6 ACs delivered" for #13355 and explicitly name the NL-created-grid integration residual.

📊 Evaluation Metrics

  • [ARCH_ALIGNMENT]: 75 - The safe projection/UI shape is aligned, but the close target reintroduces a deterministic proof where the corrected source-of-authority expected the NL-created grid seam.
  • [CONTENT_COMPLETENESS]: 78 - Good JSDoc and test evidence; PR body overclaims the corrected #13355 completion state.
  • [EXECUTION_QUALITY]: 93 - Focused diff, safe rendering, specific unit/e2e coverage, green CI; the gap is evidence scope, not code hygiene.
  • [PRODUCTIVITY]: 70 - Useful H2-visible slice, but not mergeable as the claimed capstone close.
  • [IMPACT]: 72 - Important AgentOSWidget milestone if scoped honestly; lower while the live NL provenance seam remains unresolved.
  • [COMPLEXITY]: 55 - Small UI/projection/test surface with a larger source-of-authority dependency.
  • [EFFORT_PROFILE]: Heavy Lift - This is a product-facing H2 leaf with cross-ticket foundation constraints, not a routine UI patch.

The exact-head implementation is close; the merge blocker is the graph contract. Either make this the actual #13355 NL-grid provenance capstone, or give the deterministic slice its own fully delivered close target.

PR Review Summary

Status: Approved

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

  • Decision: Approve
  • Rationale: The prior blocker was the close-target/source-of-authority mismatch, not the code. The PR now takes the requested Path 2: Resolves #13413 for the deterministic EvidencePane + local grid render-together leaf and Refs #13355 for the broader NL-created-grid provenance residual.

Peer-Review Opening: Re-review at exact head 6b89334919c308d3bc50a0d25eeccae14cc6f96f; the code head is unchanged and the graph contract is now aligned with the shipped deterministic slice.


🧭 Patch-Blind Premise Snapshot

  • Inputs Read Before Patch: #13409 current PR body, #13413 live issue body/labels, #13355 prior correction context, exact-head review from cycle 1, live CI, and the unchanged exact-head diff.
  • Expected Solution Shape: If the implementation remains deterministic, it must close a deterministic leaf and leave #13355 open for NL-created-grid provenance rather than claiming the full #13355 re-scoped intent.
  • Patch Verdict: Matches. #13413 defines the deterministic slice explicitly, the PR body no longer claims all #13355 ACs, and Post-Merge Validation names the #13355 NL-created-grid provenance residual.

🕸️ Context & Graph Linking

  • Target Epic / Issue ID: Resolves #13413
  • Related Graph Nodes: #13355, #13349, #13362, #13363, ADR 0020

🔬 Depth Floor

Documented search: I actively looked for the prior Resolves #13355 overclaim, stale "all #13355 ACs delivered" framing, and missing residual language for the NL-created-grid provenance lane. The PR now resolves only #13413 and names #13355 as residual scope.

Rhetorical-Drift Audit (per guide §7.4):

  • PR description: framing matches what the diff substantiates (no overshoot)
  • Anchor & Echo summaries: precise codebase terminology, no metaphor or source-code snapshot anchor (ticket/PR/lane/AC/cycle/line number) that overshoots durable intent
  • [RETROSPECTIVE] tag: accurately characterizes what shipped (no inflation of architectural significance)
  • Linked anchors: cited tickets/PRs actually establish the claimed pattern (no borrowed authority)

Findings: Pass. The deterministic ceiling is now framed as a design boundary, not as completion of the NL-create-path provenance lane.


🧠 Graph Ingestion Notes

  • [KB_GAP]: None.
  • [TOOLING_GAP]: None beyond cycle-1 local test setup already recorded.
  • [RETROSPECTIVE]: This is the correct close-target remediation shape: create a fully delivered leaf for the deterministic slice, keep the broader source-of-authority ticket open, and make the residual explicit.

🎯 Close-Target Audit

For every issue named as close-target, verify it does NOT carry the epic label:

  • Close-targets identified: #13413
  • For each #N: confirmed not epic-labeled

Findings: Pass.


📑 Contract Completeness Audit

  • Originating ticket (or parent epic) contains a Contract Ledger matrix
  • Implemented PR diff matches the Contract Ledger exactly (no drift)

Findings: Pass. #13413's ledger covers the EvidencePane safe text surface, scalar/fail-closed blueprint projection, and deterministic render-together grid proof that #13409 implements.


🪜 Evidence Audit

  • PR body contains an Evidence: declaration line
  • Achieved evidence ≥ close-target required evidence, OR residuals are explicitly listed in the PR's ## Residual / Post-Merge Validation section
  • If residuals exist: no residual remains for close-target #13413; the #13355 NL-created-grid provenance residual is outside this close target and is named in the PR body plus #13413 Out of Scope.
  • Two-ceiling distinction: PR body distinguishes "shipped at L because sandbox ceiling" from "shipped at L because author didn't probe further"
  • Evidence-class collapse check: review language does NOT promote L1/L2 evidence to L3/L4 framing without explicit sandbox-ceiling caveat

Findings: Pass for close-target #13413. The #13355 NL-created-grid provenance residual is no longer part of the close target and is explicitly named as separate remaining scope.

PR Review Follow-Up Summary

Status: Approved

Cycle: Cycle 3 follow-up / operator-corrected re-review

Opening: My prior approval on 6b893349 was too weak on the actual grid-render invariant; re-reviewing the new 5591cbfd delta that replaces the broad text smoke with Neo.isObject projection guarding and concrete grid-row/cell render proof.


Patch-Blind Premise Snapshot

  • Inputs Read Before Patch: Prior approval review, operator correction on the empty-grid miss, Ada's A2A update, current PR body, #13413 issue body/labels, exact-head commit list, current Neo.isObject implementation, changed files, local focused test output, and live CI.
  • Expected Solution Shape: The deterministic leaf must prove that the EvidencePane metadata and the live grid are driven by the same plain-object blueprint, and the e2e must fail if the grid mounts with zero content rows. It must not hardcode a second parallel data source, and test isolation must assert the grid's actual rendered cells rather than broad page text.
  • Patch Verdict: Matches. projectBlueprintEvidence() now uses Neo's plain-object guard, Viewport.mjs feeds cloned firstWidgetBlueprint.rows through store.data, and FirstWidgetEvidencePane.spec.mjs asserts exactly 12 .neo-grid-cell nodes plus the three row task values.

Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

  • Decision: Approve
  • Rationale: The delta repairs the precise evidence-class failure that made my previous code approval unsafe. The PR still closes only #13413 and leaves #13355's NL-created-grid provenance seam open.

Prior Review Anchor

  • PR: #13409
  • Target Issue: #13413
  • Prior Review Comment ID: PRR_kwDODSospM8AAAABDHkVHg
  • Author Response Comment ID: new head 5591cbfd / Ada A2A MESSAGE:0b21c971-dc0c-4400-afe7-ec07af1f7f1f
  • Latest Head SHA: 5591cbfd0bba36fe46a019e1c1d260989e2e423d

Delta Scope

  • Files changed: apps/agentos/childapps/widget/util/blueprintEvidence.mjs, apps/agentos/childapps/widget/view/Viewport.mjs, test/playwright/e2e/FirstWidgetEvidencePane.spec.mjs
  • PR body / close-target changes: close-target unchanged and still correct: Resolves #13413, Refs #13355
  • Branch freshness / merge state: open; current CI green at 5591cbfd

Previous Required Actions Audit

  • Addressed: Operator-caught evidence gap: previous e2e accepted a mounted/visible surface without proving real grid rows. The new e2e asserts 12 grid cells and each row's task value, so an empty grid fails.
  • Addressed: Plain-object input boundary: Neo.isObject() resolves the verbose guard into the local core primitive and rejects arrays/class instances.
  • Still open: None for #13413. #13355's NL-created-grid provenance remains explicitly outside this close target.

Delta Depth Floor

Documented delta search: I actively checked the grid data source, the e2e selector/assertion strength, and the close-target topology. The grid receives store.data from the same deterministic blueprint used by the EvidencePane; the e2e now waits on real .neo-grid-cell render output; #13413 is not epic-labeled and #13355 remains a non-closing residual.


Evidence Audit

  • Grid-render proof: Pass. The e2e no longer relies on broad toContainText; it asserts 3 rows x 4 columns = 12 rendered cells and one rendered cell for each row task value.
  • Projection boundary: Pass. Neo.isObject() is implemented as value?.constructor?.name === 'Object', matching the plain-object-only allowlist boundary.
  • Evidence-class note: This is L3 browser render proof for the deterministic leaf. It does not claim the NL-created-grid provenance path, which remains #13355 residual scope.

Close-Target Audit

  • Close-targets identified: #13413
  • Labels: #13413 carries enhancement, ai, architecture; not epic.
  • Commit-message hazard: branch commit subjects use bare (#13355) / (#13413) ticket references, not magic closing keywords.

Findings: Pass.


Test-Execution & Location Audit

  • Changed surface class: app code + unit/e2e tests
  • Location check: pass. Unit specs remain under test/playwright/unit/apps/agentos/childapps/widget/...; e2e spec remains under test/playwright/e2e/.
  • Related verification run: exact-head clean worktree at 5591cbfd0bba36fe46a019e1c1d260989e2e423d
    • git diff --check origin/dev...HEAD -> passed.
    • npm run test-unit -- test/playwright/unit/apps/agentos/childapps/widget/util/blueprintEvidence.spec.mjs test/playwright/unit/apps/agentos/childapps/widget/view/EvidencePane.spec.mjs -> 6 passed.
    • First e2e sandbox run failed only at local server/reporting permissions (listen EPERM 0.0.0.0:8080, uv_uptime EPERM).
    • After generated config bootstrap, npm run test-e2e -- test/playwright/e2e/FirstWidgetEvidencePane.spec.mjs -> 1 passed.
    • npm run test-e2e -- test/playwright/e2e/FirstWidgetEvidencePane.spec.mjs --repeat-each=3 -> 3 passed.
    • Live GitHub CI is green at this head, including unit.
  • Findings: Pass.

Contract Completeness Audit

  • Findings: Pass. #13413's deterministic grid render-together AC is now directly falsified by rendered cell count and row-value assertions. No residual remains for #13413.

Metrics Delta

Metrics are unchanged from the prior review unless an explicit delta is listed below.

  • [ARCH_ALIGNMENT]: 94 -> 96 because the projection boundary now uses the local core predicate and the grid data path is validated against real rendered rows.
  • [CONTENT_COMPLETENESS]: unchanged from prior review; PR body and #13413 still state the deterministic/residual split clearly.
  • [EXECUTION_QUALITY]: 93 -> 96 because the previous unverified render assumption is now covered by exact-head local e2e repeat proof and green CI.
  • [PRODUCTIVITY]: 88 -> 92 because the operator-caught cornerstone gap is repaired without expanding the close target.
  • [IMPACT]: unchanged from prior review; this remains the H2 evidence-pane foundation slice.
  • [COMPLEXITY]: 55 -> 58 because the proof surface is slightly stronger but still localized.
  • [EFFORT_PROFILE]: unchanged from prior review: Heavy Lift.

A2A Hand-Off

After posting this follow-up review, I will capture the review id and send Ada a wake-suppressed direct handoff so the approval does not create another broad wake.
