feat(teaching): implement ADR-0095 — Miner-Sourced Teaching Proposals

Browse source 
Closes the Phase-5 contemplation loop in code. Articulation-quality,
contradiction-detection, and frontier-compare miners (already shipping)
now have a route to file PackMutationProposal candidates that traverse
the single reviewed teaching path. Construction-only; never promotes
to coherent.

- new teaching/from_miner.py: from_finding() / from_findings() turn
  ContemplationFinding records (kind=PACK_MUTATION_CANDIDATE) into
  PackMutationProposal candidates with source.kind="miner",
  source.source_id=<miner_id>, status=SPECULATIVE
- proposal_id = SHA-256(canonical(miner_id, finding, revision))[:16]
  — same inputs → byte-identical proposal_id; different miner_id or
  revision → different id
- identity-pack defense AT CONSTRUCTION: reuses teaching.review.
  _is_identity_override() against finding.subject AND
  finding.proposed_action; miner-sourced identity-override attempts
  never reach the proposal log
- pluggable ReplayEquivalenceChecker Protocol with ReplayEquivalenceResult;
  NoOpReplayChecker default explicitly notes "deferred to production
  checker"; production checker integration is downstream of this ADR
- from_findings() batch path collects identity-override and
  replay-equivalence rejections in a typed rejection log rather than
  raising, so a mixed batch can proceed with audit evidence
- serialize_proposal_emitted_event() emits ADR-0040-compliant redacted
  telemetry shape: type, proposal_id, source.serialize(),
  epistemic_status only (no raw subject/correction_text)
- 22 unit tests covering positive construction, identity defense in
  subject+proposed_action, malformed input, determinism (same inputs,
  different revision, different miner_id, batch stream), replay
  pre-gate (single + batch), telemetry redaction, and the structural
  grep gate enforcing miner_proposal_single_review_path (only
  teaching/review.py and teaching/store.py may promote to COHERENT)
- new evals/miner_loop_closure/ lane: 6 case classes (positive_basic,
  identity_override_subject, identity_override_action,
  replay_equivalence_failed, wrong_finding_kind, determinism) passing
  6/6 with byte-identical SHA-256 across runs
- smoke 67/67, teaching 17/17, cognition 120/121 (1 pre-existing skip);
  cognition eval byte-identical 100/100/100/100

# evals/miner_loop_closure — Lane Contract
**ADR:** ADR-0095
**Invariants:**
- `miner_proposal_replay_equivalence`
- `miner_proposal_single_review_path`
## Purpose
Prove that Phase-5 contemplation miners can emit
:class:`PackMutationProposal` candidates that traverse the existing
reviewed teaching path without violating ADR-0095 hard constraints.
The lane asserts:
1. A legitimate ``PACK_MUTATION_CANDIDATE`` finding produces a
miner-sourced proposal with ``source.kind="miner"`` and
``epistemic_status=SPECULATIVE``.
2. Identity-override findings are rejected at construction, before
review, so the proposal never reaches the proposal log.
3. A finding whose replay-equivalence check fails is rejected at
construction; its ``finding_id`` appears in the batch's
``rejections`` list with reason ``replay_equivalence_failed``.
4. A non-``PACK_MUTATION_CANDIDATE`` finding raises
:class:`MinerProposalError`; the miner cannot promote diagnostic
findings into pack mutations.
5. Random/under-threshold observations (coincidence control) never
produce proposals — they are filtered upstream by the miner's
recurrence thresholds and never reach ``from_finding``.
6. Same finding stream + same miner_id + same revision → byte-identical
proposal id stream across two runs.
## Cases
The runner iterates over case fixtures declared in :mod:`runner`:
- **positive_basic** — single coherent ``PACK_MUTATION_CANDIDATE``
finding → proposal emitted with miner source.
- **identity_override_subject** — finding subject contains an
identity-override pattern → rejected at construction.
- **identity_override_action** — finding ``proposed_action`` contains
an identity-override pattern → rejected at construction.
- **replay_equivalence_failed** — finding sent through a checker that
reports trace-hash divergence → rejected at construction.
- **wrong_finding_kind** — non-``PACK_MUTATION_CANDIDATE`` finding →
raises ``MinerProposalError``.
- **determinism** — three findings emitted twice; proposal-id streams
must be identical between the runs.
## Determinism
The runner emits ``results/v1_dev.json`` with case results and a
SHA-256 of the canonical report bytes. Two consecutive runs against
the same fixtures must produce identical bytes.
## Exit code
Non-zero on any divergence between expected and actual outcomes.

"""Miner-sourced teaching proposal construction (ADR-0095).
Translates :class:`core.contemplation.schema.ContemplationFinding`
records (``kind=PACK_MUTATION_CANDIDATE``) emitted by the Phase-5
miners into :class:`teaching.store.PackMutationProposal` candidates.
The result is **never** review-eligible by itself. Every miner-sourced
proposal must traverse the same review path used by operator-authored
proposals (:func:`teaching.review.review_correction`). This module is
construction-only — it never mutates packs, never promotes proposals
to ``coherent``, and never bypasses identity defenses.
Hard constraints (ADR-0095):
1. **Single review path.** Construction emits ``SPECULATIVE`` proposals.
No code in this module promotes a proposal.
2. **Default status ``speculative``.** Inherited from
:class:`PackMutationProposal` schema.
3. **Identity-pack defense at construction.** A finding whose
``subject`` or ``proposed_action`` matches the identity-override
detector is rejected here, before review. This is an upstream
extension of :func:`teaching.review._is_identity_override` so the
miner can never even *file* an identity-override candidate.
4. **Replay-equivalence pre-gate.** A pluggable
:class:`ReplayEquivalenceChecker` runs before the proposal is
yielded. If the checker reports trace_hash divergence on any
non-target turn, the proposal is rejected at construction.
5. **Deterministic emission.** ``proposal_id`` is the first 16 hex
chars of SHA-256(canonical(miner_id, finding, revision)). Same
inputs → byte-identical proposal stream.
