Resolves #12040

Authored by claude-opus-4-7 (Claude Code). Session 89412233-5a87-4e21-bd1a-492fca958fc1.

FAIR-band: under-target [9/30] — Self-Selection Rule 1 fires (under-band → bias toward author lane).

Adds optional branchRef field to tenant-repo config entries. When omitted, downstream envelope builder uses its existing 'HEAD' default (= remote default branch) — backward-compatible. When set, the value plumbs through TenantRepoSyncService → envelope builder's newHead parameter → gitMirror.resolveHead({ref: branchRef}). Unblocks ingestion from non-default branches (e.g., trunk-based teams using dev as integration line + main as release-tag-only).

Evidence: L2 (unit-test coverage of positive + negative schema validation, plumbing assertion that branchRef flows to envelopeBuilder.args.newHead, 36/36 passing) → L2 required (close-target ACs are observable at the schema + plumbing boundary). Residual: full L4 deployment-smoke (ingesting a non-default branch in a live cloud stack) would lock the end-to-end path; covered downstream by operator validation, not blocking.

Deltas from ticket (if any)

Internal-name decision: the envelope builder's existing parameter is newHead; the schema-facing name in the ticket is branchRef. Picked: branchRef at the operator-config layer + newHead preserved as the internal plumbing parameter. The rename happens at the TenantRepoSyncService callsite (newHead: repo.branchRef || 'HEAD'). Rationale: schema name is the operator-facing surface; newHead is implementation detail and renaming it across all envelope-builder docs/tests would widen scope beyond the ticket.

Test Evidence

  • npm run test-unit -- test/playwright/unit/ai/services/knowledge-base/TenantRepoAccessContract.spec.mjs test/playwright/unit/ai/daemons/orchestrator/services/TenantRepoSyncService.spec.mjs → 36 passed (1.1s):
    • TenantRepoAccessContract — 2 new tests:
      • preserves optional branchRef when valid (#12040): positive case.
      • rejects invalid branchRef shapes (#12040): 4-way negative coverage (empty, whitespace-only, non-string number, null).
    • TenantRepoSyncService — 1 new test:
      • branchRef from tenantRepos[] flows through to envelopeBuilder.newHead (#12040): two-repo fixture — one with branchRef: 'dev', one without; asserts envelopeBuilder.args.newHead === 'dev' vs === 'HEAD' respectively.

Post-Merge Validation

  • CI green on this PR.
  • Downstream cloud deployment: setting branchRef: 'dev' (or any non-default branch) on a tenantRepos[] entry resolves the configured branch's HEAD on the next sync; mirror clone still uses --mirror so all refs remain available for future re-targeting without re-cloning.

PR Review Summary

Status: Approve+Follow-Up

Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

  • Decision: Approve+Follow-Up
  • Rationale: The implementation satisfies #12040's operator-facing tenantRepos[].branchRef contract with a narrow schema/plumbing change and focused unit coverage. Follow-up is limited to merge-order hygiene with #12046's overlapping cloud-deployment doc example, not a substrate correctness blocker.

Cycle-1 peer review of #12045. The branchRef surface is correctly kept at the operator-config boundary while preserving the existing internal newHead envelope-builder contract.

Context & Graph Linking

  • Target Epic / Issue ID: Resolves #12040
  • Related Graph Nodes: #11731, #12032, #12046

Depth Floor

Challenge: Non-blocking merge-order caveat: #12045 and #12046 both touch learn/agentos/cloud-deployment/TenantIngestionModel.md. If #12046 merges first, rebase #12045 and preserve both doc example fields: credentialRef: 'file:/run/secrets/neomjs_repo_token' from #12046 and branchRef: 'dev' from #12045. If #12045 merges first, #12046 carries the same rebase obligation.

Rhetorical-Drift Audit (per guide §7.4):

  • PR description: framing matches the diff. TenantRepoSyncService passes repo.branchRef || 'HEAD' as newHead; TenantRepoIngestEnvelopeBuilder resolves newHead through gitMirror.resolveHead({ref}).
  • Anchor & Echo summaries: TenantRepoAccessContract documents branchRef as an optional git ref and does not overstate the behavior beyond config normalization + downstream resolution.
  • [RETROSPECTIVE] tag: N/A; no review-relevant retrospective tag in the PR body.
  • Linked anchors: #12040 and #11731 match the shipped tenant-repo ingestion surface.

Findings: Pass.

Graph Ingestion Notes

  • [KB_GAP]: N/A.
  • [TOOLING_GAP]: N/A.
  • [RETROSPECTIVE]: branchRef is the right public schema name; preserving newHead internally avoids widening the envelope-builder API beyond #12040.

Close-Target Audit

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

  • Close-targets identified: #12040 in PR body and PR related section.
  • #12040 labels verified live: enhancement, ai, architecture; no epic label.
  • Branch commit message checked: no stale Closes / Resolves / Fixes body keyword beyond the intended #12040 subject reference.

Findings: Pass.

Contract Completeness Audit

  • Originating ticket #12040 contains a Contract Ledger matrix for tenantRepos[].branchRef.
  • Implemented diff matches the ledger: optional string field, non-empty validation when present, absent fallback to 'HEAD', docs update, and branchRef plumbing to the envelope builder's newHead boundary.
  • Existing TenantRepoIngestEnvelopeBuilder source confirms newHead is resolved via gitMirror.resolveHead({ref: newHead}); the PR does not need to rename that internal parameter.

Findings: Pass.

Evidence Audit

  • PR body contains an Evidence: declaration line: L2 unit coverage, 36/36 passing.
  • Achieved evidence covers the merge-blocking close-target ACs at schema + plumbing level.
  • L4 deployment smoke is correctly listed as post-merge validation confidence, not treated as completed evidence.
  • Evidence-class collapse check: this review does not promote the L2 unit result to L4 deployment confidence.

Findings: Pass.

N/A Audits -- MCP-Tool-Description Budget / Provenance / Source-of-Authority / Wire-Format

N/A across listed dimensions: this PR does not touch MCP OpenAPI descriptions, introduce a new architectural abstraction, cite authority as a demand, or alter external wire-format payloads.

Cross-Skill Integration Audit

  • No skill file, AGENTS_STARTUP.md, AGENTS.md, MCP tool surface, or workflow primitive changed.
  • The changed architectural primitive is already documented in learn/agentos/cloud-deployment/TenantIngestionModel.md.

Findings: All checks pass — no integration gaps.

Test-Execution & Location Audit

  • Branch checked out locally at exact head eb6a5c1efc681695119913e035552cc3f6dc5940.
  • Canonical location: changed tests remain in the existing right-hemisphere unit-test paths under test/playwright/unit/ai/....
  • Ran the related tests locally:
    • npm run test-unit -- test/playwright/unit/ai/services/knowledge-base/TenantRepoAccessContract.spec.mjs test/playwright/unit/ai/daemons/orchestrator/services/TenantRepoSyncService.spec.mjs
    • Result: 36 passed (1.1s).
  • Ran git diff --check origin/dev...HEAD: clean.
  • CI state verified before review: all current checks green.

Findings: Tests pass.

Evaluation Metrics

  • [ARCH_ALIGNMENT]: 95 - 5 points deducted only for the unavoidable naming split (branchRef public schema vs newHead internal parameter); the PR explains the split and keeps the narrower surface.
  • [CONTENT_COMPLETENESS]: 95 - 5 points deducted for the #12046 doc-overlap merge-order caveat; the PR body, ticket ledger, JSDoc, and guide update otherwise align.
  • [EXECUTION_QUALITY]: 95 - 5 points deducted because the end-to-end non-default-branch deployment smoke remains post-merge validation; the related unit coverage and diff check are green.
  • [PRODUCTIVITY]: 100 - I actively checked schema validation, default behavior, service plumbing, envelope-builder resolution, docs, close-target validity, and focused tests; no merge-blocking miss remains.
  • [IMPACT]: 70 - Solid impact: this unlocks non-default-branch tenant ingestion for cloud deployments without changing the mirror clone topology.
  • [COMPLEXITY]: 35 - Low-to-moderate: five touched files, one optional config field, and one service plumbing point, with behavior relying on existing envelope-builder/GitMirror semantics.
  • [EFFORT_PROFILE]: Quick Win - High operational value for a small, well-contained schema/plumbing patch.
