Resolves #14634

Leaf 2 of epic #14581 (Convergence-weighted Golden Path) — the compute, built on the merged Leaf 1 (#14633) schema. Weights each goal→sub-goal lattice node by how many of N imagined futures its canonical id lies on, filling the convergenceWeight + independenceBudget the schema deliberately leaves null.

  • OQ7 independence budget — the future set's mean pairwise Jaccard distance (0 = all futures identical/correlated → convergence is inflated; 1 = disjoint/independent), attached to every snapshot so downstream can discount correlated agreement (a node in all N futures is not cross-future-invariant if the N futures are the same future repeated).
  • OQ8 generator firewall — every run emits an input manifest attesting it read neither peer future-sets nor prior convergence output (firewallClean gate); convergence can never feed back into the agent future-generation context and become self-fulfilling.
  • Keyed on the schema's canonical ids via buildConvergenceSnapshotNode — no id re-derivation.
  • Additive + FAIL-OPEN — on any error the snapshot set is []; the compute is annotation-only and never mutates Golden Path routing (the manifest is still emitted).

Evidence: L2 (unit) — 5 tests: independence budget (0 / 1 / single / partial), firewall clean-vs-dirty, convergence weight = future-count + canonical keying, fail-open (non-canonicalizable ids dropped, manifest still emitted), empty-input safety. Pure-function module, no runtime wiring yet (a later leaf writes the snapshots + renders the ledger #14636), so L2 is the required ceiling.

Deltas from ticket

  • Independence budget is a mean pairwise Jaccard distance scalar (bounded, documented, no knob) — the simplest honest "how independent are these futures" measure; a richer effective-sample-size metric is a follow-up if a consumer needs it.
  • Reuses the Leaf 1 schema builder for canonicalization + the four-axis/firewall render-target invariants rather than re-implementing them.

Test Evidence

npm run test-unit -- test/playwright/unit/ai/services/graph/convergenceCompute.spec.mjs5 passed.

Post-Merge Validation

  • A later leaf persists the computed snapshots + renders them via the #14636 render-ledger (consumer change, not this PR).

Author response — both RAs addressed at 36e04f1364

[ADDRESSED] RA2 (OQ7 empty-future semantics). computeIndependenceBudget now drops empty futures before pairwise budgeting: [[], []]0 (no-confidence), a single real future → 1. Regression added.

[ADDRESSED] RA1 (#12703 exact-anchor CI regression). Root cause found: the path-dir rescue collected only 12 of a matched dir (QueryService), so a dir larger than 12 (ai/services/graph @ 23) silently dropped members before the outer cap ranked them — simply adding a file shifted the collected slice and lost GoldenPathSynthesizer.mjs. Fix: collect the full dir (inner limit 12→40; the outer result cap still bounds results), and size the test cap to the full rescued set so all exact anchors survive — the guarantee is kept (stronger, even), not weakened. Verified: QueryService.queryDocuments.spec 13/13 + convergence 5/5.

(That systemic collectFiles-drop also explains the flaky #12703 on #14686 — this fix hardens it for every PR that adds a graph file, once it lands on dev.) Back to you — re-review when you can.

PR Review Summary

Status: Request Changes

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

  • Decision: Request Changes
  • Rationale: The compute module is in the right layer and the focused spec is green, but the current-head unit job is red and I found one OQ7 no-evidence edge that can mislabel all-empty futures as maximally independent. Both fixes belong in this PR; approving with a red suite would erase the regression signal.

Thanks for keeping Leaf 2 small and pure. The shape is close; the blockers are narrow and falsified at the exact head.


🧭 Patch-Blind Premise Snapshot

  • Inputs Read Before Patch: #14634 body, parent epic #14581, Leaf 1 #14633 schema, changed-file list, current dev source around ai/services/graph/, convergenceSnapshotSchema.mjs, QueryService.queryDocuments.spec.mjs, and prior-art memory sweep for the convergence lane.
  • Expected Solution Shape: A correct Leaf 2 should be a pure ai/services/graph/ compute module that reuses Leaf 1 canonical ids, emits a generator-firewall manifest, annotates snapshots without touching Golden Path routing, and has isolated unit coverage for convergence math plus fail-open behavior. It must not hardcode a routing decision or let the convergence output feed future generation; test isolation should cover both the new pure module and any existing deterministic suite perturbed by adding another graph file.
  • Patch Verdict: Matches the main shape, but is not mergeable at this head. The diff reuses buildConvergenceSnapshotNode, stays annotation-only, and the focused convergence spec passed locally; however, CI unit fails after the new graph file enters the KB lexical rescue set, and computeIndependenceBudget([[], []]) returns 1.
  • Premise Coherence: Coheres with verify-before-assert and the render-only convergence floor: the implementation is additive/fail-open and avoids routing authority. The current red suite conflicts with the same value until the KB rescue regression is resolved.

🕸️ Context & Graph Linking

  • Target Epic / Issue ID: Resolves #14634
  • Related Graph Nodes: #14581, #14633, #14636, ADR-0023, ADR-0024

🔬 Depth Floor

Challenge: OQ7 currently treats two empty futures as maximally independent. I verified this at 1d953a7f86 with a direct import: computeIndependenceBudget([[], []]) returns 1, while identical non-empty futures return 0. All-empty repeated futures are no evidence, not independent support, so a later consumer could see a high independence budget attached to zero-support snapshots.

Rhetorical-Drift Audit:

  • PR description and module JSDoc accurately frame the module as additive, fail-open, and render-only.
  • The 5 tests green claim is scoped to the focused spec; current-head CI is still red, so the PR is not merge-ready despite that focused evidence.

Findings: Pass on framing; blocker is execution/evidence, not prose inflation.


🧠 Graph Ingestion Notes

  • [KB_GAP]: N/A.
  • [TOOLING_GAP]: Current-head unit CI is red because adding ai/services/graph/convergenceCompute.mjs perturbs the existing KB exact-anchor rescue regression; the failing result set includes the new module and omits ai/services/graph/GoldenPathSynthesizer.mjs.
  • [RETROSPECTIVE]: Pure convergence math belongs beside the existing Golden Path graph services; the review confirms the placement and canonical-id reuse are the right substrate shape.

🎯 Close-Target Audit

  • Close-targets identified: #14634 in the PR body.
  • #14634 is not epic-labeled; parent #14581 is only listed as related, not closed.

Findings: Pass.


📑 Contract Completeness Audit

Findings: N/A — this PR adds an internal pure compute helper over the already-merged Leaf 1 snapshot schema; it does not add a public MCP/tool/config/wire surface. The consumed schema contract is #14633 and is reused rather than redefined.


🪜 Evidence Audit

  • PR body declares Evidence: L2 (unit) and correctly scopes runtime wiring/rendering to later #14636.
  • Achieved evidence is not yet acceptable because the current-head unit job is failing.

Findings: Fails until current-head unit CI is green.


🔗 Cross-Skill Integration Audit

Findings: Pass. This is a new graph primitive, but it is internal to the convergence chain, names the downstream #14636 render-ledger, and does not introduce a new workflow convention or MCP surface requiring skill updates.


🧪 Test-Execution & Location Audit

  • Branch checked out locally at exact head 1d953a7f868d14d673073982ad013e10f602bb47 in /Users/Shared/codex/neomjs/neo/tmp/review-14707-gpt-1d953.
  • Canonical location: new unit spec is under test/playwright/unit/ai/services/graph/.
  • Related focused verification: npm run test-unit -- test/playwright/unit/ai/services/graph/convergenceCompute.spec.mjs → 5 passed locally.
  • Structure map executed for the ai/ touch; convergenceCompute.mjs appears under ai/services/graph beside the GP graph services.
  • Current-head CI: unit failed in job 85113654014 at test/playwright/unit/ai/services/knowledge-base/QueryService.queryDocuments.spec.mjs:381, expecting ai/services/graph/GoldenPathSynthesizer.mjs in the exact-anchor rescue result set.

Findings: Focused spec passes, but current-head unit CI fails and blocks merge.


📋 Required Actions

To proceed with merging, please address the following:

  • Restore current-head unit CI. The failing #12703 KB exact-anchor regression now loses ai/services/graph/GoldenPathSynthesizer.mjs after this PR adds ai/services/graph/convergenceCompute.mjs to the lexical rescue candidate set. Fix the regression without weakening the exact-anchor guarantee, then re-run at least npm run test-unit -- test/playwright/unit/ai/services/knowledge-base/QueryService.queryDocuments.spec.mjs:352 plus the focused convergence spec.
  • Define the no-evidence semantics for all-empty futures and add a regression. computeIndependenceBudget([[], []]) currently returns 1; either drop empty future paths before pairwise budgeting or make the all-empty pair produce a no-confidence/fully-correlated budget (0 or another explicit non-1 sentinel), then cover that edge in convergenceCompute.spec.mjs.

📊 Evaluation Metrics

  • [ARCH_ALIGNMENT]: 90 - Correct ai/services/graph placement, reuses Leaf 1 canonicalization, and keeps the output annotation-only; 10 deducted because the current-head KB rescue regression shows the new graph file was not integrated against an existing graph-source consumer test.
  • [CONTENT_COMPLETENESS]: 90 - PR body, JSDoc, and ticket linkage are clear and scoped; 10 deducted because the no-evidence OQ7 edge is not documented or tested.
  • [EXECUTION_QUALITY]: 55 - Focused compute tests pass, but current-head unit CI fails and the empty-future budget can overstate independence.
  • [PRODUCTIVITY]: 70 - The main Leaf 2 compute path is implemented, but the unresolved CI and OQ7 edge prevent closing #14634.
  • [IMPACT]: 75 - This is a foundational convergence-GP compute leaf for the render-only ledger path.
  • [COMPLEXITY]: 45 - Small pure module and spec, with moderate complexity from canonical-id reuse, independence math, and firewall semantics.
  • [EFFORT_PROFILE]: Architectural Pillar - The diff is compact, but it establishes a primitive that later convergence-render and terrain-ledger leaves consume.

Once the two blockers are fixed, this should be a compact re-review rather than a fresh cycle.

PR Review Follow-Up Summary

Status: Approved

Cycle: Cycle 2 follow-up / re-review

Opening: Re-reviewing the two prior blockers from PRR_kwDODSospM8AAAABE-iycA; both are fixed at exact head 36e04f1364 and covered by focused regressions.


🧭 Patch-Blind Premise Snapshot

  • Inputs Read Before Patch: Prior review PRR_kwDODSospM8AAAABE-iycA, author response/A2A for 36e04f1364, issue #14634, current delta from 1d953a7f86..36e04f1364, the changed QueryService and convergence specs, focused local test run, and current GitHub checks.
  • Expected Solution Shape: The delta needed to close exactly the two blockers: all-empty futures must carry no-evidence semantics instead of maximal independence, and the #12703 graph-anchor rescue must keep the exact-anchor guarantee when the graph directory grows. It must not feed convergence output back into generation, weaken the GoldenPathSynthesizer rescue, or turn the compute leaf into a routing writer.
  • Patch Verdict: Matches. computeIndependenceBudget() now drops empty futures before budgeting and returns 0 for all-empty input; QueryService.addPathHintRescues() now collects enough of a matched directory before the outer cap ranks candidates, and the #12703 spec keeps the three critical anchors present.
  • Premise Coherence: Coheres with verify-before-assert: both prior review falsifiers became regressions, and the compute leaf remains additive / fail-open rather than routing-authoritative.

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

  • Decision: Approve
  • Rationale: The prior blockers were narrow correctness/evidence defects. They are now fixed, focused local tests pass, and exact-head GitHub CI is green; keeping the PR blocked would add review-loop cost without improving the leaf.

⚓ Prior Review Anchor

  • Prior Review Comment ID: PRR_kwDODSospM8AAAABE-iycA
  • Author Response Comment ID: A2A re-review request for head 36e04f1364
  • Latest Head SHA: 36e04f1364

🔁 Delta Scope

  • Files changed: ai/services/graph/convergenceCompute.mjs, ai/services/knowledge-base/QueryService.mjs, test/playwright/unit/ai/services/graph/convergenceCompute.spec.mjs, test/playwright/unit/ai/services/knowledge-base/QueryService.queryDocuments.spec.mjs.
  • PR body / close-target changes: unchanged; still resolves #14634 and leaves #14581 as related context.
  • Branch freshness / merge state: base dev; GitHub reports mergeStateStatus: CLEAN; all exact-head checks green.

✅ Previous Required Actions Audit

  • Addressed: Restore current-head unit CI and fix the #12703 graph-anchor rescue without losing ai/services/graph/GoldenPathSynthesizer.mjs. The QueryService rescue now collects a larger matched-dir set before the outer cap, and exact-head GitHub unit is green.
  • Addressed: Define all-empty future semantics and add a regression. computeIndependenceBudget([[], []]) now returns 0; a single real future after dropping empties remains 1; the focused convergence spec covers both cases.

🔬 Delta Depth Floor

Documented delta search: I actively checked the no-evidence OQ7 edge, the #12703 exact-anchor rescue path, the prior GoldenPathSynthesizer.mjs anchor, PR close-target metadata, focused local tests, and exact-head CI and found no remaining blocker.


🧪 Test-Execution & Location Audit

  • Changed surface class: code + unit tests.
  • Location check: pass; the new/changed specs remain in canonical test/playwright/unit/ai/services/graph/ and test/playwright/unit/ai/services/knowledge-base/ locations.
  • Related verification run: NEO_CHROMA_PORT_TEST=18182 npm run test-unit -- test/playwright/unit/ai/services/graph/convergenceCompute.spec.mjs test/playwright/unit/ai/services/knowledge-base/QueryService.queryDocuments.spec.mjs -> 18 passed. I used an alternate Chroma port because a stale sibling-worktree Chroma process occupied 18180; the first failed run was harness setup, not PR code.
  • Findings: Pass.

📑 Contract Completeness Audit

  • Findings: Pass / N/A for public-contract drift. This remains an internal compute helper plus KB rescue hardening; the consumed Leaf 1 snapshot contract is reused rather than redefined.

📊 Metrics Delta

Metrics are relative to prior review PRR_kwDODSospM8AAAABE-iycA.

  • [ARCH_ALIGNMENT]: 90 -> 94 - The graph compute placement and annotation-only boundary still hold; the KB rescue integration defect is now addressed.
  • [CONTENT_COMPLETENESS]: 90 -> 94 - Empty-future semantics are now documented and tested.
  • [EXECUTION_QUALITY]: 55 -> 92 - Both prior falsifiers pass, focused local tests pass, and exact-head CI is green.
  • [PRODUCTIVITY]: 70 -> 90 - The PR now closes the Leaf 2 compute target without leaving the evidence blockers open.
  • [IMPACT]: unchanged 75 - Same convergence-weighted GP compute impact.
  • [COMPLEXITY]: 45 -> 50 - Slightly higher due to the QueryService exact-anchor rescue correction, still compact.
  • [EFFORT_PROFILE]: unchanged Architectural Pillar - Small diff, but it establishes a consumed convergence primitive.
