Summary

  • Remount after Phase 9 leakage FAIL on c18d7948 (receipt digest bf80a213…). PR [codex] 0.18 decontamination: planner, timing, verify, inventory #2101 remains the failed-candidate record.
  • Strengthens check-packet-generalization-boundary for citation_owns_*, domain PacketEvidenceRole variants, and holdout probe spellings (closes CX-04 false green).
  • Deletes domain carrier/role steering from production selection (CX-01/CX-02) and holdout probe matcher arms (CX-03).
  • New freeze head: 0a48b0c0dc5390b944463f4dc8a14c85a23a798f. New sealed Phase 9 corpus required. Phase 10 blocked.

Refs #2098

Test plan

  • node scripts/check-packet-generalization-boundary.mjs
  • node --test scripts/tests/check-packet-generalization-boundary.test.mjs
  • cargo test --locked -p codestory-agent
  • metamorphic + packet_generalization_boundary rust suites
  • focused runtime packet_ lib tests (taxonomy tests ignored, not reintroduced)
  • adversarial Phase 9 on this new freeze (new sealed corpus)

Land the anti-contamination checker, docs, CI wiring, and failing
black-box agent tests before planner deletion on the decontamination lane.

Introduce Stage B graph planning with frozen initial limits and
unit coverage for empty, connected, and vocabulary-only inputs.

Co-authored-by: Cursor <cursoragent@cursor.com>
Delete domain flow classifiers, cleanup passes, and flow-template claim
surfaces; keep generic seeds and Stage B repository evidence planning, and
flip the generalization boundary gate to expect a clean head.

Co-authored-by: Cursor <cursoragent@cursor.com>
Prove Stage B planning stays stable under rename, paraphrase, wrapper
depth, multi-impl, distractors, truncated graphs, and six language paths.

Co-authored-by: Cursor <cursoragent@cursor.com>
Lock Stage B constants after the visible metamorphic suite passed so later
performance replay cannot silently retune relationship search bounds.

Co-authored-by: Cursor <cursoragent@cursor.com>
Strip carrier-coupled evidence predicates to Never, delete unused scoring
and probe leftovers, and ignore runtime packet tests that still expect
deleted flow taxonomies.

Co-authored-by: Cursor <cursoragent@cursor.com>
Stage sealed core generations under core/generations with atomic
publication.json pointers and process-crash matrix coverage.

Replay retrieval lexical base/delta compaction, incremental core wall
receipts, and the incremental refresh microprobe onto the clean head.

Replace exact-candidate warm_ms=wallMs aliases with InstalledAgentTimingV1

Skip dense-anchor writes on sealed cores and advertise

Strengthen the packet generalization boundary for ownership predicates,
domain PacketEvidenceRole variants, and holdout probe spellings, then delete
those production selection paths on a new r2 candidate.

Failed freeze — do not merge as 0.18 candidate

Phase 9 leakage FAIL on head 0a48b0c0 (receipt digest b8f47dec…). Remount continues on codex/2099-v018-decontamination-r3 with required-probe seam redesign. Phase 10 blocked.

Superseded. Failed Phase 9 on holdout probe-table steering. Active work is #2103.
