I read this as a constrained verification task - I will locate and read the authoritative Task26 plan and ledger, execute only Gate 19, verify inactivity, and write a private receipt.


I read this as a constrained verification task - Gate 19 is complete and stopped at its verdict.

FAIL: exact matrix command exited 4 because `tests/gateway/test_telegram_room_bootstrap_adversarial.py` is absent.

- Candidate manifest and wheel SHA-256 pins matched.
- Service remained `inactive/dead` with `MainPID=0`.
- Receipt (0600): `.omo/evidence/task26/task26-gate19-50685ac2c063c5b18fa895cc1991e3473368d177c7309bf54af0374ea67ba1d1-fail.json`


I read this as a focused Gate 19 repair investigation - I will trace the missing matrix test against the plan, current source closure, nearby tests, and Git history before making only a canonical restoration if required.


I read this as implementation of the Gate 19 coverage restoration and strict verification - I’ll inspect the canonical test fixtures and gate contract, then restore only the missing adversarial coverage needed for the current state machine.


I read this as restoration of genuinely absent Gate 19 coverage - the obsolete eight-phase matrix does not match the current four-state private-DM bootstrap, so I’m adding deterministic restart coverage for all four current nonterminal states plus the missing owner-review stale and exact-duplicate assertions.


I read this as verification of the restored narrow coverage - I’ll run diagnostics and the affected deterministic tests under the same network-isolated, read-only boundary before defining the amended Gate 19 matrix.


I read this as quality-gating the amended test surface - the focused tests pass; I’ll now collect exact pytest node IDs and run static/compile checks in isolation, preserving the existing candidate and wheel pins because only test coverage changed.


I read this as finalizing the canonical Gate 19 definition before the strict run - Ruff and isolated compilation pass; Ty reports 11 pre-existing diagnostics in the older observability test (none in the new file), so I’ll retain that separately and execute the full deterministic matrix without masking it.


I read this as execution of the amended strict Gate 19 matrix - I’ll run its collected exact nodes once in a network-isolated read-only sandbox, with only ephemeral pytest/JUnit mounts writable, and capture service state before and after.


I read this as validating the successful strict run and its bindings - the complete amended matrix passed 23/23 while the service remained inactive; I’ll verify the retained JUnit, source/candidate hashes, and worktree scope before issuing the private PASS receipt.


I read this as conditional candidate rebinding - the restored test changes the candidate’s sealed repository-status snapshot, so preserving the old manifest would leave it unverifiable; I’ll reseal with the unchanged wheel and re-arm locally from the existing provider receipt, without any provider, Telegram, or service action.


I read this as producing the final Gate 19 evidence - the candidate artifact itself is unchanged by the test-only restoration, so I’ll preserve its pins and bind the exact test-source hashes, JUnit, quality results, and inactivity proof in a 0600 PASS receipt.


I read this as repairing the receipt serialization only - the strict matrix remains passed; the receipt writer rejected a formatting assumption in the captured stdout, so I’ll inspect that artifact and regenerate the receipt from parsed results without rerunning tests.


I read this as final receipt validation - I’ll verify the PASS receipt’s hashes, modes, matrix/source bindings, JUnit totals, and final inactivity state, then stop at Gate 19.


I read this as Gate 19 completion - restored current-state coverage and verified the amended matrix.

PASS: 23/23 strict Gate 19 tests passed in network-isolated read-only bwrap. Candidate pins were preserved; service remains `inactive/dead`, `MainPID=0`.

Receipt (0600): `.omo/evidence/task26/task26-gate19-50685ac2c063c5b18fa895cc1991e3473368d177c7309bf54af0374ea67ba1d1-receipt.json`
SHA-256: `59f601d0a75bec8f74fa10db2e40f5092cf31205643869bad307196db77431fa`

Ruff, compileall, and Ty for the new test passed. The receipt records 11 pre-existing Ty diagnostics in the older observability test.


I read this as a sealed-candidate Gate 19 verification - I’ll bind to the new Gate 18 receipt and candidate artifacts, prove the adversarial test is in the sealed executable closure, then run the exact matrix once in the required isolated surface without changing source or runtime state.


I read this as preflight for the new sealed candidate - Gate 18 binds the manifest, wheel, reused provider receipt, and arm receipt; I’ll now verify all 375 sealed source entries and the repository snapshot, including every exact Gate 19 node, before executing the matrix.


I read this as the decisive Gate 19 execution - the new candidate verifies cleanly, all 23 matrix nodes are sealed, and the restored adversarial test hash is bound; I’ll run those exact nodes once with network isolation, a read-only host root, and only ephemeral/evidence mounts writable.


I read this as binding the successful run into a new candidate-specific verdict - the isolated matrix passed 23/23; I’ll validate its JUnit, post-run closure and service state, and the Gate 18 provider/arm pins before writing the private receipt.


I read this as issuing the new sealed-candidate verdict - all required checks are clean, so I’ll preserve the new run’s exact command and JUnit artifacts and write a 0600 PASS receipt bound to the 5e6f candidate, Gate 18 provider pin, and arm pin.


I read this as completing receipt serialization only - artifact copies succeeded, and the writer missed an import before creating any receipt; I’ll regenerate the receipt atomically from the already-validated run without rerunning Gate 19.


I read this as final receipt verification - I’ll validate the 0600 PASS artifact, its exact candidate/provider/arm/JUnit bindings, and final service inactivity, then stop at the Gate 19 verdict.


I read this as Gate 19 completion for the new sealed candidate - the isolated matrix passed and the new receipt is bound to its pins.

PASS: 23/23 exact nodes, 0 failures/errors/skips.

Receipt (0600):
`.omo/evidence/task26/task26-gate19-5e6f2f2a01321ac89c2950e511e7346d23070c51146c14c22c04db54034b28f1-receipt.json`
SHA-256: `acc64624b90bbffda9af77aa7712192c41de2bbfd73c0e9b4e45d43400ca102b`

Verified:
- Candidate manifest `0422f192...`, wheel `6a3f5f04...`, provider and arm pins.
- All 375 sealed closure entries; all 23 matrix nodes, including the restored adversarial test, are sealed.
- Service remains `inactive/dead`, `MainPID=0`.
- No provider request, launch, Telegram action, source edit, commit, push, release, or activation.
