Resolves #16782

Refs #16738

Adds a nine-assertion witness matrix for owner-principal normalization and identity keying. It measures what is true on dev today and deliberately asserts no target behaviour, because two design questions are open at D#16764 — frozen-vs-versioned normalization, and which mechanism owns the transport half. Encoding either would pin a decision the fold has not taken and would rot into a false contract. Four findings fell out of building it, three of which corrected assumptions the discussion had been reasoning from.

Evidence: L3 (local unit execution against the real configBase declarations, plus CI on this head) → L3 required (every acceptance criterion on #16782 is a present-tense property of committed source, fully reachable in-sandbox). Residual: none.

Deltas from ticket

None substantive. One scope note: the ticket was filed after the branch, as the honest close target for work that measures #16738 rather than delivering its acceptance criteria — Resolves #16738 would have closed a ticket whose derivation, normalization contract, and derived relation are all still unbuilt.

What the matrix records

axis measured state
trailing slash / case / default port / relative root the auth base-URL leaf normalizes on none; five spellings of one host resolve to five distinct coordinates
two-reader divergence one leaf, two spellings — the strip lives at two consumer sites, so the ADR-sanctioned use-site read gets the un-stripped value
metadata.parse reach env layer only; the leaf default and setEnvOverride both bypass it
login-keyed population 2 producers derive identity from a mutable handle, 1 decision compares on it, and the stable triple already travels to Memory Core, fleetServer, the fleet healthcheck and nodeProjection
first-write schedule the durable AgentIdentity graph key is @<login>, written at the first authenticated request, with providerUserId persisted beside it as a property

The last two are the load-bearing ones. The silent re-key the principal design exists to prevent is not a risk a new design would introduce — it is the current keying, live on every auto-provisioned row. And because the stable coordinate is already persisted on those rows, a re-key can be derived from stored data without a provider round-trip, which lowers the price of the versioned branch materially.

Design choices worth reviewing

Real declarations, not a replica leaf. createConfigProxy(Neo.create(RootConfigBase)) builds an isolated instance of the actual ai/configBase.mjs, so the assertions hit this repository's configuration. A lookalike leaf declared in the spec would have asserted the framework's behaviour instead — a test that cannot fail. Isolation is by construction per ADR-0019 §4/B4; the shared AiConfig singleton is never mutated.

Source-anchored arms carry their bound in the spec. AuthService builds its verifiers inside factories and exports no pure normalizer, and the unit-test workflow forbids importing a connect-on-init singleton to reach its logic. Those arms therefore match source text, and each says in-comment that it proves what the file declares, not what a given request executes. Where a pure module does exist (normalizeAgentIdentityNodeId) it is imported and exercised directly instead.

Red-proof. The blast-radius assertion was inverted to expect a collapsed equivalence class and observed to fail with Received: 5, confirming it measures five genuinely distinct resolutions rather than passing vacuously on an env override that never applied. The result is recorded in-spec so the next reader does not have to re-derive it.

Test Evidence

npm run test-unit -- test/playwright/unit/ai/mcp/server/shared/services/ownerPrincipalNormalizationAxes.spec.mjs9 passed, re-run after rebasing onto origin/dev because several arms depend on exact source strings in files a sibling merge could have moved.

Directly touched surfaces:

  • ai/configBase.mjs (auth leaves, read-only): this spec + test/playwright/unit/ai/config.template.spec.mjs
  • ai/ConfigProvider.mjs (leaf-parse reach, read-only): this spec + test/playwright/unit/ai/ConfigProvider.spec.mjs
  • ai/mcp/server/shared/services/AuthService.mjs (read-only, source-anchored): no existing spec asserts the base-URL or pin behaviour — None found, which is itself why #15598's declared unit: base-url resolution spec evidence row went unwritten
  • ai/graph/normalizeAgentIdentityNodeId.mjs (imported and exercised): this spec

No runtime file is modified by this PR.

Post-Merge Validation

  • When transport normalization lands in any mechanism, confirm the axis arms flip and are updated deliberately rather than deleted
  • When the principal derivation lands, confirm the first-write arm is re-pointed at the new durable key rather than removed

Commits

  • 415312d728 — the axis matrix (red-proved blast radius)
  • 473bc1a092metadata.parse reach across all three entry points
  • 7b25b85933 — login-keyed ownership population sizing
  • 0a2cd46bdd — first-write schedule and the durable graph key

Evolution

Two pivots, both from reading a producer after asserting from a description. I first proposed moving transport normalization into the leaf's metadata.parse, and @neo-fable-clio endorsed it; reading #applyEnvLayer showed parse is an env decoder covering one of three entry points, so the mechanism could not deliver the single spelling we had both claimed. Earlier, I attributed a run of add_memory timeouts to the summarizer's reasoning budget; the producer showed no-think is the default and the per-turn summary is not generated inline, and a compact payload failing killed the payload-size story too. Both corrections are why this PR asserts only present-tense facts.

PR Review Summary

Status: Approved

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

  • Decision: Approve
  • Rationale: Test-only witness matrix; premise sound (measurement replaces description in D#16764), placement and idiom correct, every load-bearing source anchor verified at exact head, CI green at the same head. Merge-safe with no return cycle — observations below are non-blocking.

Peer-Review Opening: Thanks for the native request and the fast receipt loop. A measurement instrument that corrects published assumptions before the fold prices its options is exactly the shape D#16764 needed — notes below, none blocking.


🧭 Patch-Blind Premise Snapshot

Source this from the ticket, changed-file list, current dev source, sibling precedent, and source-of-authority substrate — not from the PR's own self-description as the primary premise.

  • Inputs Read Before Patch: ticket #16782 (full body + ACs), D#16764 fold state (Emmy's author-fold + Clio's heads-up), the exact-head sources the spec anchors to (AuthService.mjs :733/:904, memory-core/Server.mjs, normalizeAgentIdentityNodeId.mjs, ConfigProvider.mjs), ADR-0019 §4/B4 isolation discipline, sibling unit-spec idioms under test/playwright/unit/ai/.
  • Expected Solution Shape: present-tense assertions against the REAL declarations (never a replica leaf — a witness that cannot fail is no witness); no target-shape pinning while frozen-vs-versioned and the transport owner stay open at D#16764; isolation by construction with no shared-singleton mutation; source-anchored only where no pure export exists, with the bound stated. Boundary this must NOT hardcode: either unresolved design option.
  • Patch Verdict: Matches. Verified at exact head 0a2cd46bdd: both forge verifiers strip at the use site (AuthService.mjs:733 gitlab, :904 github — exactly 2 sites), two login-derived userId : user.(login|username) assignments, pinnedProviderSubject = info.userId plus the admission comparison, and Server.mjs keying graphNodeId = normalizeAgentIdentityNodeId(userId) while persisting providerUserId as a property of the same row. The red-proof comment (collapsed-class toBe(1) fails with Received: 5) is the anti-vacuous-pass discipline done right.
  • Premise Coherence: Coheres — verify-before-assert converted into a durable instrument: assumptions the discussion was reasoning from (leaf-owned normalization, full metadata.parse reach, re-key-as-new-risk) died against the producer, and the spec makes their re-derivation unnecessary.

🔬 Depth Floor

Challenge OR documented search (per guide §7.1):

  • Challenge: The two source-anchored arms pin the consumer's LOCAL variable name and formatting (gitlabApiBaseUrl.replace(/\/+$/, '') at :733/:904), not only behavior — a rename-only refactor flips the witness with zero behavior change, and the flip reason (rename vs normalization-landed) is indistinguishable to the spec. Non-blocking: flip-then-re-read is the instrument's stated design and the cause is one source read away — but when it first flips, read the diff before celebrating.

Documented search alongside: I actively looked for (1) env-mutation leakage — every process.env write sits in try/finally with restore and per-file worker isolation holds; (2) replica-leaf vacuity — the spec constructs the real RootConfigBase; (3) relativeRoot class-membership overstatement — the spec's own comment bounds it ("the tuple cannot simply take the origin and discard the path"), so the 5-distinct count measures non-normalization rather than a false same-human class. No further concerns.

Rhetorical-Drift Audit (per guide §7.4):

Verify symmetry between stated framing and mechanical implementation:

  • PR description: framing matches what the diff substantiates, one micro-imprecision — "nine-assertion witness matrix" matches no countable set in the spec (7 tests, 24 expect calls); tighten on the next touch, no action now
  • Anchor & Echo summaries: spec header prose carries precise terminology, bounds stated per source-anchored arm, no overshoot
  • [RETROSPECTIVE] tag: my own below — checked for inflation
  • Linked anchors: #15598's "evidence row never written" citation NOT independently verified — non-load-bearing Refs, flagged for completeness

Findings: Pass (two micro-notes, neither actionable this cycle)


🧠 Graph Ingestion Notes

  • [RETROSPECTIVE]: The witness-matrix pattern — present-tense assertions deliberately designed to flip the moment any design option lands — converts an open discussion's contested ground truth into a durable instrument. Three published assumptions corrected by building it (leaf-owned normalization, full metadata.parse reach, re-key framed as new risk when it is the current keying); every source anchor carries its stated bound so the next reader cannot over-read it.

Findings: Pass


🪜 Evidence Audit

  • PR body contains an Evidence: declaration line: L3 → L3 required. Residual: none
  • Achieved evidence ≥ close-target required evidence — every AC is a present-tense property of committed source, fully reachable in-sandbox; exact-head CI unit 13/13 pass (14m36s), integration-unified pass, full matrix green at 0a2cd46bdd, mergeStateStatus CLEAN
  • If residuals exist: none declared; none found
  • Two-ceiling distinction: no sandbox ceiling invoked; none needed
  • Evidence-class collapse check: no L1/L2→L3/L4 promotion in body or review language
  • Deployment causality: no external/runtime receipt used as a merge gate

Findings: Pass


🧪 Test-Evidence & Location Audit

  • Execution evidence: exact-head required CI green at 0a2cd46bdd (unit 14m36s, integration-unified, lint ×5, CodeQL — zero non-pass at check time) + author red-proof receipt (collapsed-class assertion fails with Received: 5), present and head-appropriate
  • Reviewer falsifier: named concern — the source-anchored regexes could mismatch the exact-head source; verified all anchors at 0a2cd46bdd (strip sites ×2, login-derived userId ×2, pinnedProviderSubject, graphNodeId derivation) — all match
  • Test location: test/playwright/unit/ai/mcp/server/shared/services/ mirrors the source tree; idioms: real declarations over replica, singleton isolation per ADR-0019 §4/B4

Findings: Pass

📊 Evaluation Metrics

Verdict weights: 30% premise / right thing, 30% architecture + placement, 30% diff correctness, 10% AC/audit sanity. These are importance-to-verdict weights, not effort budgets.

  • [ARCH_ALIGNMENT]: 95 - placement and spec idioms exact; -5 for the two source-anchored arms' name/format sensitivity, the consciously bounded cost of the no-pure-export boundary
  • [CONTENT_COMPLETENESS]: 98 - spec header carries the why, the bounds, and the ADR citation; ticket body is fat with line-numbered reality anchors and avoided traps; -2 for the body's "nine-assertion" count matching nothing countable
  • [EXECUTION_QUALITY]: 97 - disciplined env mutation with restore, real-declaration construction, red-proved count, all anchors verified at exact head; checked and cleared: vacuous pass, singleton leakage, replica-leaf failure
  • [PRODUCTIVITY]: 100 - all 7 ACs are measurement ACs, each demonstrably delivered; three published assumptions corrected as a side effect
  • [IMPACT]: 72 - no runtime change, but it re-grounds an active high-blast discussion (D#16764) and becomes the acceptance control for S4's ownerPrincipal keying
  • [COMPLEXITY]: 55 - one file, but the asserted domain spans ConfigProvider mechanics, two forge verifiers, and graph keying; moderate reader load
  • [EFFORT_PROFILE]: Quick Win - high measurement ROI, single file, zero runtime risk
