Foundation for L10 resume-as-same-life persistence. Adds:
- core/array_codec.py: a leaf (numpy+base64) codec encoding arrays as
{dtype, shape, b64(raw bytes)} — BIT-EXACT, never decimal. Float round-trips
lose zero precision, so a restored versor keeps versor_condition < 1e-6 and a
replayed turn keeps its trace_hash. dtype carries byte order; float32 is never
conflated with float64.
- field/state.py: FieldState.to_dict/from_dict. Multivector arrays (F, holonomy)
go through the byte codec; energy/valence round-trip exactly via JSON-safe
helpers (lazy physics imports keep field/ cycle-free).
Exit gate (the scope's #1 risk, de-risked first): bit-exact round-trip AND
closure preserved — versor_condition(restored.F) == versor_condition(fs.F)
exactly. 10 codec/FieldState tests + 55 architectural-invariant/runtime tests
pass. Purely additive; no existing behavior changed.
Part of docs/analysis/L10-shapeBplus-persistence-scope-2026-06-05.md (Phase A).
Add ManifoldState (N,32) versor field over graph edges, GraphDiffusionOperator
with damped convergence via construction_seed_versor closure, deterministic
hash-to-versor stub, and run_pulse.py end-to-end script proving injection →
propagation → vault recall → token output. 24 new tests, zero regressions
on architectural invariants.
Three items from the post-assessment stabilization slice:
1. field/state.py: restore frozen=True, slots=True
slots=True closes __dict__ on FieldState instances, preventing
incidental attribute injection that frozen=True alone does not block.
The holonomy field works cleanly with slots because ndarray | None
is a valid slotted field type in Python 3.12.
2. README.md: correct vocab/ layer description
Was: 'Word-to-versor manifold, edge rotors'
Now: 'Surface-token manifold points; indexed access for algebraic
transition construction'
Edge rotors are constructed by algebra/, not stored in vocab/.
This exact confusion caused vocab.edge_rotor() drift in earlier work.
3. AGENTS.md: add language-pack checksum rule
Manifest checksums MUST be computed by reading back the bytes
written to disk (Path(f).read_bytes()), never from in-memory strings
before serialization. Unicode-escaped JSON on disk != Python str.
- field/state.py: FieldState is now frozen+slotted; constructor copies and
enforces float32 shape (32,); advance() updated to pass raw arrays.
np.ndarray inside frozen dataclass is ref-frozen — copy() at construction
is the explicit contract boundary.
- generate/result.py: NEW — GenerationResult frozen dataclass carrying
tokens + final_state. Async variant yields tokens and exposes final_state
on completion.
- generate/stream.py: generate() now returns GenerationResult, not list[str].
vocab.edge_rotor() call replaced with:
A = vocab.get_versor_at(current.node)
B = vocab.get_versor_at(word_idx)
V = word_transition_rotor(A, B)
agenerate() updated to yield tokens and surface final_state.
- vocab/manifold.py: added get_versor_at(idx) and get_word_at(idx) indexed
accessors. VocabManifold stores points; algebra constructs operators.
normalize_to_versor() call-site in docstring clarified: callers must call
unitize_versor() (algebra construction primitive) before add(), not
normalize_to_versor() directly.
- algebra/versor.py: unitize_versor() added as the explicit construction-time
primitive. normalize_to_versor() kept but marked internal/gate-only.
Distinction encoded in docstrings and __all__.
- persona/motor.py + ingest/gate.py: SessionContext.respond() is not yet in
the repo as a separate file; gate.py docstring updated to reflect the
three-tier normalization doctrine:
unitize_versor() — algebra construction only
inject() — gate, once per raw input
normalization — forbidden in propagate/generate/vault recall
