A repaired summary spine changes bytes, so the evidence gate reads the next fold's dropped spine as uncovered and rejects every later fold. Score the spine against continuation facts, repair or abort, and record each adopted handoff for the archive to certify.
A cap that slices the repair tail used to ship a spine that still missed exact names, and the scorer treated auth as present inside authored. Abort any residual after the cap, and match tokens on word boundaries.
A tight cap used to slice exact names off the repair tail. Put goal, next action, and exact names first so truncation keeps the facts the next agent needs, and restore real verify coverage on the truncation path.
Re-scoring the aborted original summary was tautological. Assert the outcome misses, add a roomy-cap repair control, abort on a constraint-only residual, and reject author/preauth as auth hits.
Substring includes let oauth.ts cover auth.ts. Match names on token boundaries, emit only missed constraint/blocker/verification lines, and assert a real verify signal after folds.
Interior dots join filenames and hostnames so vite.config.ts does not cover config.ts. HTTP URLs lowercase before hostname scoring. Drop unused ContinuationFacts.state.
`new URL` keeps a trailing period in the hostname, so a summary that names api.com misses Call HTTP://API.COM. as an exactName.
Bun-hosted ts-prune under-reports unused exports on Linux, so CI treats a still-valid allowlist as stale. Launch the CLI with node.

Summary
Compaction verify pass so the goal survives many folds: after each fold the spine is scored against continuation facts (goal, state, next action, constraints, verification, blockers, exact names). Missing facts are repaired deterministically; contradicting summaries abort the fold instead of shipping a lying spine. Adopted handoffs are recorded in the evidence archive so later folds can drop the spine, and the summarizer excerpt pins the initiating goal ahead of the recency window.
Target release: 0.3.31.
