"""Rule-status proposals from the plane's memory store (harnessx-removal Req 6.2/6.4, design section 5).

The store (:mod:`..plane.memory`) holds what plane runs learned per repository and pin. Two deterministic rules turn
its ``alert`` and ``verdict`` rows into :class:`RuleStatusEdit` proposals that :func:`.evolve.run_round` validates
and gates exactly like the benchmark's own edits; a third reads dispute rates as advisory routing input only.

Join key: an ``alert`` and a ``verdict`` match when repo, pin and ``path::function`` are equal. A ``disputed``
final counts as no evidence in either direction.

- **M1, repeated false alerts** (``enabled -> shadow``): at least :data:`M1_MIN_FALSE` alerts of the rule are false
  -- at a ``rejected`` candidate, or on a ``fixed`` pin inside the declared fix range (the alert row says
  ``in_fix_range: true``, or its ``path::function`` is a ``site_match`` site of the same repository) -- across at
  least :data:`M1_MIN_REPOS` repositories, and no alert of the rule sits at an ``agreed`` or ``site_match``
  candidate.
- **M2, missed declared sites** (``shadow -> enabled``): the shadow rule's alerts hit at least :data:`M2_MIN_HITS`
  ``agreed`` candidates with ``site_match`` true across at least :data:`M2_MIN_REPOS` repositories, no enabled rule
  alerts at those candidates, the rule has no ``fixed``-pin alert at the same function, and at most
  :data:`M2_MAX_REJECTED` alert at a ``rejected`` candidate.
- **M3, disputed families**: families with at least :data:`M3_MIN_CANDIDATES` candidates and a dispute rate of at
  least :data:`M3_MIN_DISPUTE_RATE`. Advisory (``signals.json``); never an edit, never shown to the validator.

**Coverage**: M1 and M2 skip every repository and pin whose ``coverage`` rows record the rule's language only as
``none`` (quick mode had no rule for it and no engine alerts were produced): a rule cannot be demoted or promoted
on evidence that could not exist. The skipped alerts are counted per ``repo@pin`` under ``coverage_none`` in the
proposal's ``excluded``.

**Train-on-test guard** (:class:`Guard`), applied before any rule sees a row: a row is dropped when its population
is one the proposal will be qualified on, its (repo, pin) is a case of the gated benchmark manifest, or its
repository is a holdout pair's repository. The pair catalog records a holdout pair's *fix* commit, not the
vulnerable pin (its parent), so the holdout clause matches by repository, a superset of (repo, pin). This is the
rule the closed-loop leak broke, where a holdout pair taught the shape that then "recovered" it.

**Provenance**: each proposal's rationale is ``memory:<proposal_id>``, ``proposal_id`` being the sha256 of (rule,
edit key, sorted evidence row ids, thresholds). The sidecar ``memory_proposals.jsonl`` next to the journal carries
the evidence rows (id, repo, pin, run, task, object key and version -- the bucket's object version id, a file's content hash),
the counts that met each threshold, what the guard excluded and the store's index digest.
