The include is authoritative, but feat/bugfix/ship-feature/init-project
each restate the verify loop inline — an orchestrator following the
restatement alone would have skipped the floor. Each now carries the
GATE 0 bullet ahead of GATE 1 (4 new structure locks, flip-tested).
The contract-interview weight table stops promising a hotfix oracle
nothing executes: hotfix runs no floor, the hotfixer runs the suite
itself. CHANGELOG extended with the wiring + the RED result.
GATE 1 is an LLM dispatch and the verifier's mandatory PROOF: line is a line
the verifier writes — nothing structurally stops it being produced without
anything being executed. Nothing deterministic sat between the executor and
that dispatch.
An acceptance criterion can now carry an oracle: indented CHECK: (command),
EXPECT: (success-only marker), EVIDENCE: (slot). lib/gates.sh runs them
fail-closed — MET requires exit 0 AND the marker, so a nonzero process never
passes on its error text carrying the token — and writes the outcome back
into the contract, so the fresh verifier reads evidence as fact rather than
trusting the executor's report.
GATE 0 runs that floor before any verifier is dispatched; a red build sends
the executor back for free, on its own iteration budget. ABANDON: <id>
<reason> turns an impossible criterion into a visible handoff that blocks
CONFORME and routes to the human gate, via the new ABANDONED(n) verdict —
a distinct token because it routes distinctly, never a dev loop. feater and
bugfixer gain a four-pass completion discipline, scoped so a pass can never
widen the contract.
The runner's parse fails closed on partial oracles, duplicate ids,
unindented attributes and runnable criteria with no EVIDENCE: line, and
executes nothing at all when the ledger is malformed. status never executes
and never writes; run always re-executes, since trusting written evidence is
the failure being closed.
Adapted from the unlazy skill (Leonxlnx/unlazy, MIT). Its Stop hook,
approval store, .unlazy/ tree, depth-tree arithmetic and Node checker were
deliberately refused — BDR-083 records each reason.
64 assertions in lib/tests/gates.test.sh, non-execution proved by sentinel
with its own positive control asserted first.
lib/contract-interview.md: mandatory upstream passage for all orchestrators.
Verbatim REQUEST (immutable), proportional questions (complete request =
zero, max 3 one batch), testable criteria + file scope, written to disk
immediately (.claude/tasks/contracts/<date>-<slug>-<HHMM>.md — a context-only
contract dies at compaction). Lifecycle: enrichment only at human gates
([gated] marker, scope micro-gate), supersedes for re-scope, aborted runs
deleted or committed status:aborted — never left dirty. Hand-off = path,
not restatement.
agents/verifier.md: fresh read-only verifier. Reads the contract from disk,
renders VERIFY — VERDICT: CONFORME | ECARTS(n) | ERROR. Blind: never
receives iteration history. PROOF line mandatory (LRN-048), UNVERIFIABLE
never MET, mute verifier never a PASS (retry once fresh, 2nd structural
failure = human escalation). Orchestrator protocol documented in-file
(max 3 iterations, re-verify request before security).
lib/tests/contract-verifier.test.sh: 31 deterministic structure locks on
the load-bearing doctrine clauses — green, shellcheck clean.
Behavioral dogfood (2 fresh subagents on a planted fixture): gap case →
ECARTS(2) exactly as planted (NOT-MET located + out-of-scope flagged);
conform case with injected fake iteration history → CONFORME, noise
ignored, real python spot-check as evidence. Both outputs parse-clean.
