Full lane wall-time: 6:35 → 2:25 (2.7× speedup). No behavioral
changes; same 1933 passed, 2 skipped.
Three wins, biggest first:
1. pytest-xdist as a project dependency.
``pyproject.toml`` gains ``pytest-xdist>=3.6``. ``cmd_test``
injects ``-n auto`` for ``--suite full`` when xdist is importable;
curated suites stay single-process because worker-spawn overhead
is net-negative on the smaller suites. Operator can override
via passing ``-n <N>`` or ``--dist`` explicitly.
Verified: ``core test --suite full -q`` prints ``bringing up
nodes...`` and parallelises across the runner's CPUs.
2. Module-scoped fixture for run_demo() in test_learning_loop_demo.py.
The 7 demo tests each previously called ``run_demo(emit_json=True)``
from scratch — and ``run_demo`` itself runs the cognition lane
twice via the replay-equivalence gate. ~15s/file → ~3s/file.
Module scope (not session) is intentional: pytest-xdist
distributes by test, so a session-scoped fixture would still be
re-evaluated per worker that picks up a test from this file.
Module scope keeps the cost paid once per worker per file, which
is the actual lower bound.
3. Module-scoped fixture for the teaching-loop bench.
``test_teaching_loop_bench.py``'s 5 tests previously each ran
``run_teaching_loop_determinism(runs=2 or 3)`` — 12 pipeline
invocations across the file. One ``runs=3`` invocation shared
across all 5 tests covers every assertion: ~25s → ~7s.
For local iteration, ``core test --suite cognition -q`` etc. remain
fast (no xdist overhead). The full-lane speedup is most visible
under CI / pre-merge runs.
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.
`core demo learning-loop` (+ `--json`) walks a single prompt through the
full ADR-0055..0057 inter-session-memory architecture:
S1. Cold turn → universal disclosure, grounding_source=none
S2. Discovery emission → DiscoveryCandidate to attached sink
S3. Operator proposal → real replay-equivalence gate, no regression
S4. Operator accept → TRANSIENT corpus only; active untouched
S5. Same prompt → teaching-grounded surface with the new chain
Before / after on the deterministic prompt "Why does thought exist?":
before: [none] I don't know — insufficient grounding for that yet.
after: [teaching] thought — teaching-grounded (cognition_chains_v1):
cognition.thought; logos.internal. thought reveals meaning
(cognition.meaning). No session evidence yet.
The active corpus on disk is byte-identical pre/post. The demo writes
only to a transient corpus, then swaps `_CORPUS_PATH` for the after
turn — the same pattern the replay-equivalence gate uses.
- evals/learning_loop/run_demo.py — `run_demo(emit_json=False)` returns
a structured `DemoReport` with both surfaces and per-scene detail.
- core/cli.py — `core demo learning-loop` target wired.
- tests/test_learning_loop_demo.py — 7 tests pin: full loop closes,
before is ungrounded, after contains new chain atoms (thought /
reveal / meaning), discovery emits ≥1, replay gate reports no
regression, S4 byte-identical active + 1 line on transient, same
prompt drives both surfaces.
Lane state: learning-loop-demo 7 new — green. Demo runs in ~15s
end-to-end (cognition lane runs twice via replay gate).
No LLM provider has a published equivalent of this loop: per-fact
provenance from operator accept to surface, replay-equivalence gate
proving non-regression, byte-identical active state regardless of
outcome, full audit trail back to the originating cold turn.
