Closes the user-flagged scope gap: every previous fluency lane (Phase
5.1 + 5.4-5.7 + grammatical_coverage) operates on 3-word SVO probes.
These three pieces stress paragraph-scale generation, give per-stage
latency visibility, and expose the realizer's word-choice geometry —
all on top of the existing deterministic infrastructure.
# discourse_paragraph lane (paragraph-scale fluency)
Forces the realizer to emit multi-sentence paragraphs from a
multi-step ArticulationTarget with rhetorical moves (ASSERT, SEQUENCE,
ELABORATE, CONTRAST). Same realizer, much richer input — every case
is 3-5 sentences with deterministic discourse markers.
Public 12 cases / holdouts 5 / dev 1 across 12 + 5 topic chains
(epistemic, scientific method, creation arc, logical dependency,
ethical grounding, linguistic layers, mathematical chain, narrative,
biology, physics, two contrast-shaped, musical, social, computational,
psychological, economic).
Sub-metrics per case:
- sentence count (within min..max window)
- subject coverage rate
- discourse marker presence (next / furthermore / in contrast)
- sentence-initial capitalization
- replay determinism (run twice, surfaces match)
Result: 12/12 public + 5/5 holdouts at 100%, replay rate 100%, mean
sentence count 4.
# Realizer capitalization (G4, addresses user-flagged concern)
generate/realizer.py gains `_capitalize_sentence` + `_join_as_paragraph`
helpers. Sentence-initial alphabetic characters are now uppercased
(skipping leading whitespace/punctuation). Surfaces went from
"wisdom grounds knowledge. next, knowledge requires evidence."
to
"Wisdom grounds knowledge. Next, knowledge requires evidence."
The discourse_paragraph runner ships a strict per-sentence
capitalization check so future regressions get caught.
# Pipeline-stage profiler (benchmarks/pipeline_profiler.py)
External monkey-patch wrapper around CognitiveTurnPipeline.run() that
records per-stage ns budgets without editing any pipeline source.
Stages: intent, graph_planner, realize_semantic, runtime_chat,
maybe_transitive_walk, fold_walk_into_surface, run_teaching,
trace_hash.
API: `profile_turn(pipeline, text) -> ProfileReport` with
`.stages: dict`, `.total_ns: int`, `.as_dict()`.
Empirical: runtime_chat dominates >99% on the runtime hot path (which
is correct — that's where ingest + propagate + recall + articulate
all happen). Future optimisation work has a clear per-stage signal.
# Word-selection tracer (benchmarks/word_selection_tracer.py)
External wrapper around generate.articulation._resolve_slot that
records every nearest-neighbor lookup as a WordSelectionStep:
- slot (subject/predicate/object)
- input versor (32-d copy)
- top-K candidate words by CGA inner product
- chosen word + morphology
- output language
Top-K scoring uses the diagonal Cl(4,1) metric kernel from
algebra.backend (same vectorised path vault_recall uses), not a
per-word Python loop over cga_inner. No approximation, exact
deterministic ranking, bit-identical to a scalar scan.
API: `trace_realization(pipeline, text) -> RealizationTrace` with
`.steps`, `.realization_steps`, `.surface`, `.as_dict()`.
# CLI lane registration
Cognition suite now sweeps the benchmark profiler/tracer tests
(test_benchmarks_profiler.py) so any future regression in the
instrumentation surfaces immediately.
# Constraints honoured
- Zero edits to core/, chat/, vault/, teaching/, language_packs/, or
the algebra hot path. All instrumentation is external monkey-patch
with originals restored in finally.
- discourse_paragraph runner bypasses ChatRuntime grounding (named v2
gap) so paragraph capability is isolated to the realizer.
- No semantic changes; no hidden normalisation; no approximate
recall.
# Lane health
smoke 55, runtime 19, teaching 17, packs 6, cognition 105 (was 103),
algebra 132. All Phase 5 fluency lanes still 100% with the
capitalised surfaces (rubric is case-insensitive). discourse_paragraph
100%.
# What ships next (named v2)
- Round-trip: discourse_paragraph through ChatRuntime end-to-end,
not just realize_target.
- Per-sentence grammatical_coverage rubric on each emitted sentence.
- Longer chains (10/20/50 sentences) with per-sentence determinism
scaling curves.
- compose_relations operator to lift compositionality recall from
68.8% toward 100%.
