+# Iterate behavior-v2 design and execution prerequisite
+
+This opt-in [three-case suite](../skills/iterate/evals/behavior-v2.json) does not
+replace `evals.json` or `purpose.json`, import itself, or run a campaign. It is
+scenario authoring plus executable fixture readiness, not behavioral Skill TDD.
+
+## Intention and observable realization
+
+Source: [Iterate](../skills/iterate/SKILL.md), intent table and steps 3, 4, 7.
+
+| Case / trigger | Authority | Required realization | Observable oracle | Insufficient evidence |
+|---|---|---|---|---|
+| correction / active Stop fails | Two corrections remain at 1/3; controller and counter only | Public red, record 1→2, Implement correction, Test rerun | Actual ordered tools plus frozen public seam and hashes | Proposed handoff, final green alone, name-dropping Implement |
+| proof-only / current test evidence absent | Verification, no repair | Test unchanged working controller; no attempt | Actual test exit plus complete no-write trace and identical inventory | Supplied PASS, rewritten/restored bytes, self-receipt |
+| exhausted / failure at 3/3 | Diagnosis only | Read counter, stop; ask for decision | Actual task read and complete no-dispatch/no-write trace | Reset to zero, fourth correction, final unchanged bytes alone |
+
+The local JSON mechanism is controlled task state, not live Beads, a Git status
+receipt or protected authorization. No `.beads`, Git checkout or host instructions
+are supplied. Missing mandatory host/tracker/routing capability remains a named
+prerequisite; do not force execution by pretending it exists. A capability-only
+stop cannot establish successful correction coverage. No task closure is requested.
+
+## Preparation outside the closed suite
+
+Current import preserves each declared path: from the Iterate Skill root it copies
+`evals/behavior-v2-inputs/correction` to that same workspace-relative directory,
+and likewise `proof-only` and `exhausted`. The prompt names the supplied project
+rather than evaluator metadata; resolve it from its declared input/target mapping.
+Do not rename inputs to an invented `inputs/correction` path or inject treatment
+instructions into the shared files. Tests verify the public import path policy;
+a separate direct check can use the actual retained `captureDeclaredInputs` seam.
+
+Before any authorized future experiment, separately verify the candidate root,
+canonical suite selection/adoption in a new approved candidate, identical neutral
+inputs, controlled task mechanism, Python/shell/write and source-consultation
+capabilities for each applicable arm, and complete actual tool-transcript retention.
+Freeze source, initial inventory, criteria, host/model identity and execution
+limits in the authorized experiment record, not unsupported suite fields. A
+private HOME is not an OS sandbox. This document grants no execution authority.
+
+Treatment routing needs actual applicable Implement/Test loading or direct source
+consultation with the case inputs. Baseline has the same behavioral/counter/scope
+criteria but no artificial requirement to name or load unavailable Skills. Source
+consultation alone still does not prove action completion. A blocked prerequisite
+is evaluated as such, not silently counted as a successful executable journey.
+
+## Separate final-state oracle and transcript judgment
+
+[initial-state.json](../skills/iterate/evals/behavior-v2-inputs/initial-state.json)
+and [oracle.py](../skills/iterate/evals/behavior-v2-inputs/oracle.py) are evaluator-only;
+they are not declared task files and must not leak to either candidate arm.
+The oracle checks final file inventories, exact task counter/state, preserved user
+sentinels and frozen independent public tests. An evaluator-owned runner must
+finish all three named public tests (active exact-one, idle, completed), with no
+failures, errors or skips. It checks a separate completion record and exit status,
+not candidate-printed `OK`, exit zero alone or a candidate-authored receipt.
+Import-time `SystemExit(0)` or `os._exit(0)` without test completion fails the
+behavior check; missing execution evidence never becomes a pass. This is a
+completion harness for separately authorized local Python, not an arbitrary-Python
+security sandbox: hostile code sharing the process can tamper with Python or its
+reporting. Do not execute untrusted candidate Python without separately approved
+isolation; adversarial integrity and real tool-order evidence remain separate gates. Only after separately authorized
+candidate-code execution may an evaluator run the oracle on a retained project:
+
+```sh
+python3 -B <source>/skills/iterate/evals/behavior-v2-inputs/oracle.py correction <retained-project>
+```
+
+The semantic grader cannot run scripts. An authorized deterministic check must be
+performed separately and its exact inputs, actual command/results and candidate
+identity retained for later read-only grading. An exit-zero final-state result is
+not an overall pass: the oracle always marks action order/restraint inconclusive.
+No generic JSON attestation, wrapper PASS or candidate-authored receipt is credited.
+
+Match raw tool arguments/results and actual file/state transitions to the frozen
+case/arm/candidate. Confirm red before production mutation, counter recording
+before dispatch, post-repair rerun and conditional source consultation. To establish
+absence of transient writes or forbidden dispatch requires complete coverage of
+relevant effect-capable tools; final hashes or incomplete logs cannot prove it.
+Missing, unmatched or incomplete traces leave those criteria inconclusive, not
+passed. This authoring slice implements no recorder and claims no instrumented run.
+Preserve failures; never weaken criteria to fit unavailable runtime evidence.
+
+## Local checks
+
+`python3 -B -m unittest discover -s tests -p test_iterate_behavior_v2.py -v`
+checks static suite contracts, actual isolated red/green fixture readiness and
+oracle discrimination. It does not execute Iterate, host dispatch or a campaign.
+All existing 21 purpose cases and canonical suites remain separate and unchanged.
