I read this as an evidence-generation task - I’ll inspect the exact acceptance contract and immutable artifacts, execute only its permitted offline checks (including the integration exactly once), then write and permission-check both redacted receipts.


I read this as reaching the execution preflight boundary - candidate/archive/wheel authentication is available, but the only retained immutable pre-clean fixtures are pinned to earlier candidate digests; I’m checking whether an existing candidate-653 derivation or exact integration harness closes that mismatch before deciding PASS versus fail-closed.


I read this as a successor-seal bundle task, superseding the impossible 653 checkpoint - I’ll preserve 653 unchanged, authenticate the latest immutable trainer-free fixture/harness as a separate input, execute its network-isolated integration exactly once plus focused checks, and emit append-only bundle/checkpoint/re-audit artifacts marked `READY_FOR_SUCCESSOR_SEAL_NOT_TASK26_PASS`.


I read this as starting the one-shot verification phase - both immutable inputs now authenticate, so I’m running the disposable full-path handler once under `--unshare-net`, then the non-integration focused suites separately to avoid a second handler execution.


I read this as a verification-harness issue isolated from the successful one-shot integration - the 653-focused suite passed 21/21, while the auxiliary snapshot’s broad non-integration command reported failures after five passes; I’m narrowing that auxiliary failure without rerunning the real-handler path or changing any sealed input.


I read this as sealing the append-only evidence bundle now - the required 653 and fixture checks are complete, the one permitted handler run passed exact counts, and I’m writing only private successor-input receipts while leaving candidate authority explicitly pending.


I read this as a fail-closed contract conflict discovered during final bundle validation - the inventory requires `gateway/platforms/task23_portable_coach_successor.py` in closure, while its required candidate-bound trainer-free test requires that same module to be absent; I’m appending a superseding FAIL receipt rather than falsely marking the successor input ready.


I read this as final verification of the fail-closed deliverable - I’m authenticating both immutable inputs again and validating the superseding bundle’s hashes, permissions, 23 field records, one-shot integration count, and explicit non-authority status.


I read this as final delivery - report the fail-closed successor bundle and decisive contract contradiction.

**Verdict: FAIL.** Candidate 653 remains unchanged and is not authorized for Task26 or successor sealing.

Decisive contradiction:

- Inventory requires `gateway/platforms/task23_portable_coach_successor.py` as a closure root.
- Candidate source and wheel do not contain it.
- Candidate-bound `test_legacy_runtime_modules_are_absent` explicitly requires that same module to remain absent.

Therefore unchanged source/wheel cannot satisfy both requirements. The contract owner must remove the root requirement or restore the module and revise the absence test before creating a successor seal.

Verified:

- Candidate 653 immutable verifier: PASS before and after.
- Immutable fixture verifier: PASS.
- Focused candidate tests: 21 passed.
- Network-disabled real-handler integration: exactly one invocation, PASS with all expected counts.
- Systemd: inactive/dead, MainPID 0; stale JSON PID classified as diagnostic history.
- Task22 permissions and hashes: PASS.
- Bundle: directory `0700`, all 13 receipts `0600`, 23 field records present, JSON/LSP validation clean.

Earlier READY artifacts in the bundle are explicitly superseded by the authoritative v2 FAIL manifest and receipt.


I read this as rebuilding only the append-only evidence envelope against the superseding v2 contract - I’ll authenticate the new inventory, supersession receipt, prior test/integration receipts, immutable inputs, and cleanup observations without rerunning behavior, then append a new READY checkpoint, re-audit, and authoritative bundle manifest.


I read this as the contract-authentication phase passing - the v2 inventory hash is exact, its supersession receipt hash is exact, and the prior behavioral receipts remain private and hash-stable; I’m appending the corrected absence-aware closure and v3 authoritative seal-input receipts without executing tests, integration, services, or Git.


I read this as tightening the sealer handoff before finalizing - the rebuilt bundle is READY, and I’m adding a complete leaf-level sealer index covering the entire immutable 653 envelope, all 719 closure sources, the actual immutable fixture state, contracts, and every receipt, then making that index the authoritative manifest’s handoff.


I read this as final evidence-only validation - the complete sealer index now covers 19 immutable candidate files, 719 closure leaves, five fixture leaves, both v2 contract artifacts, and every bundle receipt; I’m checking the authoritative v4 digest graph and 23 field bindings without touching behavioral surfaces.


I read this as completed successor-seal bundle delivery - report the authoritative v4 outputs and verification status.

**PASS — successor-seal input only.** Status: `READY_FOR_SUCCESSOR_SEAL_NOT_TASK26_PASS`.
