I read this as an independent adversarial verification of Todo 5 - I’ll inspect the plan, live implementation and contracts, run the required deterministic suites and QA, then write only the requested evidence JSON without modifying product or tests.


The fixed implementation worktree exists separately from the plan workspace. I’m now binding the corrected evidence to the live worktree hashes and tracing the adapter-to-stepper-to-polling call chain before executing any tests.


The evidence hashes match the live source files, but its `candidate_authority` does not match the live append-only registry and is non-authoritative for this source-only Todo. Static inspection also exposed an adversarial edge to exercise directly: malformed Telegram IDs can fall back from the durable stepper into the legacy mutation path, so I’m testing that fail-closed boundary alongside the required suites.


Verification reached reproducible blockers rather than a clean confirmation: malformed `update_id` bypasses the stepper and mutates the nutrition cursor without a projection, and the required strict type gates fail on the new integration test and QA script. I’m recording the rejection with exact commands, passing regression context, stale-authority disposition, and cleanup proof.


I read this as completed adversarial verification - I found reproducible blockers and recorded them.

```


I read this as a delta-only re-review of the three prior Todo 5 blockers - I’ll preserve the frozen approvals, inspect only the corrected malformed-ingress, strict-typing, QA, authority, hash, regression, and cleanup evidence, then replace the verdict JSON.


The delta inspection shows the intended three-way typed disposition and legacy fallback only for `not_applicable`; the corrected evidence has no `candidate_authority` field, and the new strict surfaces contain no `Any`, `cast`, suppression, skip/xfail, placeholder assertion, or private bridge-state shortcut. I’m now executing only the named delta gates.


All delta gates are green: malformed applicable text and callbacks are reserved without mutation/publication, both strict type checkers and LSP are clean with zero shortcuts/suppressions, the manual oracle emits one exact JSON object while exercising the required fault/identity cases, the 205-test matrix passes, authority is absent, hashes match, and temporary assets are absent.


I read this as completed delta-only verification - all prior blockers are closed.
