ADR-0021 v1 schema land. epistemic_status is a position in the revision
graph, not a source-trust tier — coherence is the only admission signal.
Surfaces:
- teaching/epistemic.py: EpistemicStatus enum (COHERENT, CONTESTED,
SPECULATIVE, FALSIFIED); ADMISSIBLE_AS_EVIDENCE = {COHERENT}.
- PackMutationProposal.epistemic_status (default SPECULATIVE) + immutable
with_status() updater.
- ReviewedTeachingExample.epistemic_status (default SPECULATIVE);
orthogonal to acceptance per ADR §Schema impact.
- LexicalEntry.epistemic_status (default "coherent" for seed; absent in
JSONL is treated as the seed default — no retroactive tagging).
- compute_trace_hash + trace_hash_from_result + pipeline.py fold the
load-bearing proposal's epistemic_status into the trace hash so
replay detects different epistemic frames.
Non-hardening invariant (ADR-0021 §2): tests/test_epistemic_invariants.py
asserts no final/frozen/axiom/permanent flag on PackMutationProposal or
ReviewedTeachingExample, and EpistemicStatus contains no source-trust
tier names.
Docs: docs/runtime_contracts.md gains an Epistemic surface section.
Lanes green: smoke 27/27, teaching 10/10, packs 6/6, runtime 19/19,
cognition eval 100%.
Add RuntimeConfig with English default output policy, wire output language through runtime/frame selection/generation/CLI, preserve language metadata in mounted manifolds, and add runtime/CLI policy tests.
Compile language-pack features into even-grade rotors, apply canonicalization after alignment nudges. Preserves holonomy parity across token counts. 231 tests passing.
Root was 0.17, stem 0.10 — not heavy enough to anchor same-root forms
against the diverging suffix rotor (ים landing on a different axis).
New hierarchy:
triliteral root 0.13 → 0.22 (shared identity, strongest anchor)
root 0.17 → 0.30 (primary root geometry)
stem 0.10 → 0.18 (secondary, same-root forms cluster here)
inflection role 0.02 → 0.015 (key label, minimal)
inflection value 0.05 → 0.03 (number/gender/etc, perturbation only)
prefix 0.05 → 0.03 (per-position decay preserved)
suffix 0.04 → 0.02 (per-position decay preserved)
This ensures דבר and דברים both orbit the D-B-R root point closely
enough that cga_inner(singular, plural) > cga_inner(singular, unrelated),
while still encoding morphological distinctions as measurable offsets.
- VocabManifold.update(): replace a stored versor in-place (grade-norm
enforced, KeyError if word missing)
- compile_entries_to_manifold() now also returns entry_id->surface map
as a second return value; callers that only need the manifold use [0]
- _alignment_nudge_rotor(): slerp-style rotor that rotates source toward
target by edge.weight * ALIGNMENT_NUDGE_STRENGTH (0.06) — small enough
to preserve intra-pack geometry, large enough to pull cross-lang pairs
into proximity
- load_pack(): after both manifolds are built, loads alignment.jsonl,
resolves entry_id->surface on each side, applies nudge to source versor
using the already-compiled target versor as the attractor
- _is_hebrew_root() guard retained; _triliteral_root() Hebrew-only
- Guard _triliteral_root() rotor to Hebrew-script roots only; Greek/other
scripts now use the root: rotor alone (0.17) — no spurious uppercase
Unicode blade collision from the romanization fallback path
- test_structured_morphology_improves_same_root_hebrew_resonance: replace
tag_only baseline (now empty since legacy tags stripped) with no_morphology
baseline (domain+pos+lemma+surface only), which is the honest comparison
for what structured morphology contributes post-migration
