I read this as independent candidate certification - I’ll reconstruct the predecessor Gates 18–20 procedure, execute it unchanged in substance against the successor, and seal append-only evidence without touching protected state.


I’ve confirmed the successor is sealed but not deployed and the working tree is intentionally non-clean. I’m now binding execution to its manifest/closure, then running the isolated test, build, type, and installed-wheel surfaces; evidence will go to a separate append-only certification root.


The execution harness is sealed to a separate evidence root and uses read-only source mounts, network isolation, disabled caches/bytecode, and PID waits rather than sleeps or polling. I’m starting the complete run now; the full Gateway suite is the long phase.


The deterministic Gate 18/19 and successor-focused source runs passed. Two harness-level issues appeared—not candidate defects: the full suite lost its read-only profile-package dependency because `HOME=/tmp`, and the wheel test inherited a pytest warning promoted by `-W error`; the read-only UV cache also blocked its lock file. I’m preserving those adverse artifacts and rerunning only the affected surfaces with corrected disposable mounts/config, still without touching source, service, profile, network, or Git.


The canonical full suite confirms a real successor blocker: **80 failures / 8,065 passes / 59 skips**, and the minimal canonical-order reproduction fails immediately after the new activation test module leaves a fake `checkin_cli` package in `sys.modules`. The wheel build itself is byte-exact once run with the candidate’s recorded build umask. I’m running one final control suite excluding only that six-test module to separate the candidate-caused cascade from untouched baseline behavior.


I read this as completed independent certification - reporting sealed verdicts and the candidate-caused blocker.

Candidate `30bcd663...d5d1cc`:

- **Gate 18: PASS** — 1/1 golden-path test; source/wheel parity 3/3.
- **Gate 19: PASS** — 23/23 predecessor matrix; successor-focused matrix 49/49.
- **Gate 20: FAIL**
  - Full Gateway: **8,065 passed, 80 failed, 59 skipped**; 8,204 total.
  - Control excluding the new six-test module: **8,139 passed, 0 failed, 59 skipped**.
  - Installed wheel: **40/40 passed**.
  - Reproducible build matched wheel SHA-256 `2fbd6c9ad9d4b5ee979e7671d44e32fd4769e8737e26d7459fe73c81a525c656`.
  - Installed-wheel imports and new CLI help: PASS.
  - Ruff/compile: PASS.
  - New-file basedpyright: 0 errors, 0 warnings.
  - Full basedpyright: exactly four inherited errors, reproduced against parent copies without suppression.

**Blocker:** `tests/gateway/test_dualcoach_activation_cutover.py` leaves its fake `checkin_cli` modules in `sys.modules`. Subsequent tests import that incomplete package, causing the 80 order-dependent failures. Minimal reproduction: 6 passed, 1 failed.

Candidate verifier remained PASS and repository status remained byte-identical. No protected state was modified. The service was started externally during execution and was only observed, not acted upon.


I read this as a fresh Gate 20 certification for the test-isolated successor - I’ll prove candidate lineage and Gate 18/19 rebind eligibility, then run every Gate 20 surface once and seal a separate append-only verdict while preserving the prior FAIL evidence.


Lineage is sufficient to attempt rebinding: the core and wheel are byte-identical, all three production modules are unchanged, and the sole executable delta is the repaired six-test module outside both Gate 18 and Gate 19 node sets. I’m starting the fresh quality/wheel checks and the single canonical full-Gateway execution now.


The fresh canonical suite is clean: **8,145 passed, 59 skipped, 0 failed** across 8,204 tests. The repaired module is included, and the prior 80-failure cascade is absent. I’m sealing the candidate-bound Gate 20 and Gate 18/19 rebind receipts with the build, wheel, import, CLI, type, and immutability proofs.


I read this as completed Gate 20 recertification - reporting the sealed successor-bound results.

I read this as a full fresh recertification of the summary-production successor - I’ll bind the exact three-file delta and lineage, execute new Gate 18/19 candidate matrices plus one canonical full Gate 20 run, then seal a separate append-only receipt set without touching protected state.


The candidate’s intended focused matrix is the 30-test reconciliation module. I’ve also isolated two Gate 18 publication nodes: the production customer-summary card and the resolved-clarification republish path. Type classification will compare the changed files against exact reverse-diff predecessor overlays in the same workspace, so any new diagnostic cannot be mislabeled as inherited.


All behavioral gates passed, including the one required fresh Gateway run: 8,154 passed and 59 skipped. The predecessor type overlay itself reconstructed correctly, but its first checker launch could not create a UV cache lock inside the read-only sandbox. I’m preserving that invocation-error artifact and rerunning only the predecessor type checker with a writable cache bind; no test suite is being repeated.


The second launch exposed that `uvx --offline` selects its tool cache from `HOME`; rebinding the package cache alone was insufficient. The installed checker is available directly at `/home/cube/.local/bin/basedpyright` (version 1.39.9), matching the successful successor run. I’m preserving both failed-launch records and using that exact executable for the final predecessor comparison.


The candidate’s own 44-error audit reveals that “strict” means `typeCheckingMode: strict` with the repository virtualenv, not the repository’s default warning severities. I’m adding that exact strict-mode comparison for both successor and predecessor. The default-mode results remain useful supplemental evidence but will not substitute for the requested strict audit.


I read this as stop execution and report only non-authoritative partial evidence - no further commands or sealing.

**Status: STOPPED / RELEASE BLOCKED**

Blocker: persisted `activity_category` contains clarification prose rather than a canonical enum value. Candidate `e2f1699e...` is not deployable.

Partial command outcomes:

- Gate 18 nodes: 2 passed
- Gate 19 predecessor matrix: 23 passed
- Gate 19 successor matrix: 30 passed
- Full Gateway suite, run exactly once: 8,154 passed, 59 skipped, 0 failed; 8,213 total
- Installed-wheel tests: 70 passed
- Source/wheel parity: 5/5 modules byte-identical
- Rebuilt wheel SHA-256: `bd5f44592e95b152cc466446fcbb607df586dc13482d0d3413fed80a476d2a70`

No PASS receipts or receipt index were created. Source, candidate, live state, service, network/provider/Telegram, and Git were not modified. Existing receipts remained byte-identical at the completed pre/post check.


I read this as a fresh, candidate-bound recertification of `4e9962be...` - I’ll inspect its bindings and declared matrices, then run Gates 18–20 once in a new private evidence root without reusing any `e2f` result.


The candidate binds four changed files and includes exact predecessor bytes, enabling a true predecessor overlay rather than a rebound. The fresh matrices will be 99 predecessor tests and the complete 136-test onboarding surface; Gate 18 will run five exact golden-path nodes plus four-module wheel parity.


The single permitted full Gateway run completed with 22 failures caused by the network-isolated harness blocking DNS-dependent test fixtures; it cannot be rerun under the “exactly once” constraint, so Gate 20 is presently FAIL regardless of focused success. I’m correcting only the type-baseline invocation using the candidate’s bound strict configs, then I’ll seal FAIL receipts preserving this full-run result.


I read this as final certification reporting - Gates 18–19 passed, but Gate 20 failed on its sole permitted full-suite run.

## Verdict

- Gate 18: **PASS**
- Gate 19: **PASS**

### Gate 20 blocker

The network-isolated full-suite harness produced:

- 12 Discord attachment failures
- 9 Matrix media failures
- 1 runtime-footer environment failure

The suite was not rerun because Gate 20 required exactly one full execution.

I read this as an append-only adjudication of the preserved invalid-harness FAIL - I’ll bind its exact 22 JUnit node IDs, run the three causality controls, and only after they all validate run one authoritative full suite under the original host environment.


All adjudication controls passed exactly: 22/22 under normal host, 21/21 reproduced under network isolation with DNS/url-safety markers, and the footer failed only with `HOME=/tmp`. The invalid harness is proven with candidate causality zero; I’m now starting the single corrected authoritative full Gateway run.


The corrected authoritative full suite passed: 8,159 passed, 59 skipped, 0 failed. I’m now refreshing the supporting Gate 20 checks in the sibling root and will seal only after candidate, Git, service, and the entire original FAIL evidence tree remain byte-identical.


The authoritative full run and all substantive checks passed. One ancillary installed-wheel import probe launched from the repository and correctly detected source fallback; I’m preserving that invocation and correcting only the probe/CLI working directory to `/tmp`, without rerunning any targeted control or full suite.


I read this as final corrected-harness certification reporting - the adjudication succeeded and Gate 20 is lawfully `PASS_CORRECTED_HARNESS`.
