## Exit-gate rule

Every future workbench phase must end with **required Eve reads and writes
admitted with source and behavior evidence, or an exact task-0.8 explicit
non-goal proves zero operations; a named defer preserves ownership but never
passes completion**. The gate discovers post-M workbench phases from the
canonical ledger; a new phase without an explicit policy, ratified task-0.8
binding, and terminal exit task fails generation.

## Why this is fail-closed

- The terminal task must be the final top-level checklist item in its phase and
  contain the canonical marker and clause.
- Every phase is bound to an exact ratified task-0.8 required workflow and its
  complete requirement-ID set.
- Required workbench completion needs both admitted read and write operation
  classes with byte-pinned source and behavior proof.
- A defer retains owner and unblock metadata but always returns a failing
  completion result.
- A zero-operation boundary passes only with an exact task-0.8 explicit-non-goal
  workflow and requirement; missing implementation is not a non-goal.
- The candidate ratchet covers every discovered BFF/bridge operation source plus
  every source file carrying a state signal.
- The code-envelope ratchet covers all tracked production source in each domain,
  so even a novel persistence mechanism changes the reviewed digest.
- The real CLI evaluates missing-read, missing-write, deferred-required,
  source-backed non-goal, and admitted-operation cases with retained exit-code
  expectations.

## Honest limits

- This gate closes task 1.9 only. It does not complete phases Y/V/E/A/B, admit a
  new Eve view or command for those phases, or close G4.
- Every governed phase is a task-0.8 required workflow and is currently
  unavailable; its named defer preserves accountable ownership but the recorded
  completion result is false.
- The positive admitted-operation control uses Tara read and write contracts
  that already exist in the repository to prove the gate can pass real source-
  and behavior-backed operations; it does not transfer Tara coverage to
  Y/V/E/A/B.
- The zero-operation control is limited to one exact task-0.8 explicit non-goal
  about avoiding a tenth content pipeline. Absence of implementation, a defer,
  or an invented verdict cannot substitute for that source binding.
- The code-envelope ratchet covers every tracked production TypeScript,
  JavaScript, Rust, and Prisma source under each domain root plus discovered
  BFF/bridge route files; generated binaries, untracked files, runtime-only
  routes, and shared stores with no domain route reference remain outside this
  static census.
- State candidates are conservative static signals and include in-memory or pure
  stores; a candidate is a demand for an explicit disposition, not proof that
  the state is durable or operator-visible.
- Behavior evidence is repository test-harness evidence, not a staging or
  production observation. Each future phase must replace its unavailable
  disposition with its own runtime evidence before exit.
