Three issues in the drift-fix landing (922bddc) addressed:
1. algebra/rotor.py: add rotor_power(R, alpha) — slerp on the rotor manifold
via the rotor's exp/log decomposition. Handles both rotation planes
(cos/sin) and boost planes (cosh/sinh); falls back to identity for
non-simple bivectors or null cases.
2. generate/stream.py: the score-weighted vault recall previously did
`weight*V + (1-weight)*np.eye(V.shape[0])`. Two bugs:
- np.eye produced a 32x32 matrix for a 1D multivector, crashing
versor_apply with a broadcasting error (2 cognition tests failing
on main).
- The linear blend produced multivectors with versor_condition up to
2.2e-2, violating the non-negotiable 1e-6 invariant declared in
CLAUDE.md. Now uses rotor_power(V, weight) which stays on the
manifold by construction (versor_condition <= 1.1e-16).
3. session/context.py: respond() now re-binds result.final_state to
self.state after finalize_turn's anchor pull, restoring the
"respond returns the same object that was vaulted" contract
(test_engine_loop_proof regression).
Verification:
- 41 new tests in tests/test_rotor_power.py covering closure preservation,
alpha=0/1 boundaries, half-angle composition, and word-transition rotors.
- Empirical multi-turn versor_condition stays at machine epsilon with
anchor pull, max 9.4e-7 without (under threshold either way after fix).
- Full suite: 609 passed, 4 skipped, 0 failed.
1. session/context.py — dialogue blade accumulation is now magnitude-preserving
via EMA (α=0.15). Running blade grows stronger each turn a concept is
confirmed rather than resetting to unit magnitude on every record_dialogue().
2. generate/stream.py — vault recall transitions are now score-weighted.
Each recalled rotor is scaled by softmax(scores)[i] before application so
high-confidence vault hits dominate and stale low-score entries barely move
the field.
3. session/context.py — anchor pull added after _hemisphere_consistent_field().
A mild α=0.05 slerp toward _anchor_field is applied at finalize_turn() to
provide continuous conjugate correction against angular drift within the
hemisphere. Unitized before writing back to state.
_orient_result_to_anchor used np.dot (Euclidean dot product) alongside
cga_inner to decide hemisphere flips. When CGA inner was positive
(correct hemisphere) but Euclidean was negative, the flip negated CGA
alignment — making correctly-oriented fields rank last in vault recall.
Changes:
- Move hemisphere check into finalize_turn so all paths (ChatRuntime,
SessionContext.respond) get consistent protection.
- Use CGA inner product only, removing the forbidden Euclidean metric.
- Remove _orient_result_to_anchor (subsumed by finalize_turn).
- Remove SessionContext.arespond (dead code, no callers).

- Fix running_dialogue_blade grade explosion: replace outer_product
accumulation (which pushed past grade-5 in Cl(4,1), silently zeroing
the blade from turn 3 onward) with CGA-inner-oriented blade tracking
that preserves grade-2 across arbitrary turn counts.
- Add versor_condition guard at session composition boundary: cross-turn
field composition via versor_apply now fails closed (threshold 1e-2,
matching algebra construction residue tolerance) instead of silently
propagating degraded fields into vault and generation.
- Replace VaultStore list with deque(maxlen=max_entries): eliminates
O(N) list.pop(0) on every bounded eviction; deque auto-evicts in O(1).
- Replace O(N) vocab scan in generate/stream.py stop_nodes construction
with O(1) try/except index lookup per stop token.

Adds referent tracking, session graph traversal, unknown-domain gating, correction propagation, compositional surface assembly, and regression coverage.
Follow-up fixes included before merge:
- split probe/commit/finalize turn flow so unknown-domain checks run before current-query vault writes
- record real input tokens and input versors for sync and async session paths
- return true graph distances from backward walks and consume them in correction decay
- synchronize corrected graph outputs into vault-backed recall and live referent state
- regenerate correction responses from corrected context rather than correction text
- keep coreference pronouns lowercase in question bodies
- centralize elaboration-string construction to avoid plan/surface drift
- add targeted dialogue fluency regression tests
- remove normalization and unitization calls from generation path
- skip invalid recalled fields instead of repairing them in generation
- punctuate selected articulation surfaces
- stabilize assertive dialogue roles
- anchor proposition slots to live field
- preserve session anchor orientation for coherence
Key issues fixed:
- `CORE_BACKEND=numpy` was ignored, so tests mixed Python CGA embedding with Rust metric behavior.
- Dense construction seeds were being rejected by strict `unitize_versor()`, while sparse dirty inputs still needed to fail closed.
- Holonomy needed a construction-boundary path for raw/dense vocab fixtures and rare null final accumulators.
- Proposition storage polluted vault recall by storing the live field instead of the proposition’s subject versor.
- Dialogue qualitative frames rendered the same surface as assertive copular frames.
- Repeated session prompts could collapse into the same deterministic response path.
- Two proof fixtures were stale: one hand-built a non-null “null” vector, and one alignment proof omitted the English “with” anchor used by the resonance proof.
Verification:
`CORE_BACKEND=numpy CORE_STRICT_MLX_ON_APPLE=0 uv run core test -- -q`
Result: `277 passed in 59.52s`
