Shay 7c80b791ec fix(tests): retire 13 stale failures from full lane — corpus saturation drift
The full lane carried 13 long-standing red tests whose premises were
invalidated by reviewed-corpus growth that landed in earlier commits.
None reflected runtime bugs — all four classes are corpus-state drift
where the test fixture became stale.  Curated lanes were green, full
lane stayed quietly red.  Closes that gap.

1. test_teaching_audit (2 tests).
   * test_audit_real_corpus_runs_clean asserted dropped == () and
     lines_on_disk == lines_loaded — premise written before any
     supersession existed.  Curriculum saturation v2 (commit a0edbb4)
     ratified the wisdom_grounds_judgment → wisdom_requires_knowledge
     supersession; the audit now correctly shows 1 dropped line.
     Rewritten as the line-conservation invariant:
       lines_loaded + len(dropped) == lines_on_disk
     plus a typed-reason check on every dropped entry.
   * test_default_superseded_by_is_null_in_loaded_entries asserted
     ALL loaded entries have superseded_by == None.  Wrong even by
     ADR-0055 design: the replacement entry IS loaded and carries
     the back-pointer to the retired chain.  Rewritten as the
     active-set invariant: any non-null superseded_by on a loaded
     entry must reference a dropped (retired) chain id, never a live
     one — no double-live state.

2. test_learning_loop_demo (7 tests).
   The demo's headline prompt was "Why does thought exist?", and the
   ADR-0057 demo trilogy (commit 82dac4b) chose (thought, cause) as
   the cold cell.  Cognition saturation v2 (commit a0edbb4) ratified
   cause_thought_reveals_meaning into the active corpus — so the
   cold turn now grounds, no discovery candidate is emitted, every
   demo scene breaks.  Rotated the cold subject to ``narrative``
   (pack-resident, no chain, same thematic shape, same affirming
   evidence pointer cause_creation_reveals_meaning).  Demo headline,
   evals/learning_loop/run_demo.py, core/cli.py preamble, and the
   test assertions all updated together so the demo reads cleanly:
       before: [none]     I don't know — insufficient grounding...
       after : [teaching] narrative — teaching-grounded ... narrative
                          reveals meaning ...

3. test_discovery_candidates (4 tests).
   Test fixture used (judgment, CAUSE) as the still-cold pair.
   Epistemology v1 (commit 2acf71f) ratified
   cause_judgment_requires_wisdom — (judgment, cause) is no longer
   cold.  Rotated to ``principle`` (pack-resident, no chain on either
   intent today).  Added a pytest.skip self-guard so when a future
   curriculum unit ratifies a (principle, *) chain the test rotates
   cleanly instead of going red.

Full lane: 1892 passed, 2 skipped, 0 failed (was 4 failed pre-fix,
13 failed pre-ADR-0063).  Cognition eval unchanged: public 100/100/
91.7/100, holdout 100/100/83.3/100.

"""Learning-loop demo — CORE learning a new chain from a cold turn.
The thesis (the demo's headline claim):
> CORE, asked a question it cannot ground, emits structured evidence
> that a reviewed chain would have helped. An operator authors a
> proposal from that evidence. The replay-equivalence gate confirms
> the chain would not regress the cognition lane. The operator
> accepts. The **same prompt now produces a deterministic
> teaching-grounded surface** — and CORE will produce that same
> surface for that prompt every time, replayably, with full
> provenance back to the operator's accept.
No LLM provider has this loop. Continuous pre-training is the
nearest analog and is fundamentally different: opaque gradient
updates over uncurated data without per-fact provenance, without
operator review, without a replay-equivalence gate, without an
audit trail that lets you ask "why did the model say this today
that it would not have said yesterday?"
Five scenes, each on a real ``ChatRuntime`` against the live active
corpus. The active corpus file bytes are byte-identical pre/post —
the demo writes only to a transient corpus, then swaps ``_CORPUS_PATH``
to that transient for the "after" turn. The same swap pattern the
replay-equivalence gate uses (``teaching.replay._swap_corpus_path``).
S1. Cold turn. The runtime cannot ground the prompt.
S2. Discovery emission. A ``DiscoveryCandidate`` is emitted to the
attached sink — structured evidence, not a mutation.
S3. Operator-authored proposal. A complete proposal is built from
the candidate's structure plus operator-provided connective /
object / corpus-evidence pointer. The replay-equivalence gate
runs (real ``teaching.replay.run_replay_equivalence``) and
confirms no regression.
S4. Operator accept against a *transient* corpus. The active corpus
on disk is untouched; the accepted chain is written to a tmp
file. Audit + runtime both honour the transient corpus.
S5. Same prompt, now teaching-grounded. The deterministic
teaching-grounded surface contains the new chain's subject /
connective / object. Identical for any replay of the same
prompt against the same corpus state.
