Shay a49a7555dc feat(surface): ADR-0030 — depth-language hedge wiring
Closes the ADR-0028 'English-only differentiation' gap.  Hebrew and
Koine Greek surfaces now consult identity-pack surface_preferences for
hedge and claim-strength shaping, using language-appropriate canonical
hedge phrases.  CORE's three-language foundation (English / Hebrew /
Greek) is now uniformly identity-aware at the realizer.

Algorithm: the same four-band hedge/claim-strength logic from ADR-0028
runs for all three languages.  Thresholds and claim_strength come from
the identity pack (carried on SurfaceContext).  Hedge phrases come
from ctx for English and from a new module-level constant
_DEPTH_HEDGE_PHRASES for Hebrew (he) and Koine Greek (grc).

  he:  'נראה ש' / 'אולי' / 'במקרים מסוימים,'
  grc: 'δοκεῖ ὅτι' / 'ἴσως' / 'ἐνίοτε,'

Pack swap visibly affects depth-language output: a precision_first
identity pulls hedges to higher alignment than default; a generosity
pack pulls them to lower alignment.  Same trajectory through the
manifold → three different Hebrew surfaces under three different
packs.  Same for Greek.

Files:
  generate/surface.py
    _DEPTH_HEDGE_PHRASES (new module constant)
    _apply_hedge(surface, ctx, lang='en')   — lang param added
    _assemble_he(.., ctx)                   — ctx param added
    _assemble_grc(.., ctx)                  — ctx param added
    SentenceAssembler.assemble              — passes context to he/grc
  tests/test_identity_surface_divergence_depth.py — 15 new tests:
    Hebrew hedge bands, Greek hedge bands, pack-swap divergence in
    both depth languages, three-language hedge phrase distinctness,
    backward compatibility with ctx=None
  docs/decisions/ADR-0030-depth-language-hedge.md  — Accepted
  docs/identity_packs.md                            — closes known-limit #1
  memory/identity-packs.md                          — refreshed

Backward compat:
  - _apply_hedge default lang='en' so existing callers unaffected.
  - English surface output byte-for-byte unchanged.
  - _assemble_he / _assemble_grc with ctx=None match pre-ADR output
    byte-for-byte (asserted by TestBackwardCompatibility).

Scope limits (documented in ADR):
  - Depth-language hedge phrases are canonical defaults, not per-pack
    overridable yet.  Future ADR may add a 'languages' block to the
    pack schema if a downstream deployment needs override capability.
  - Contrast ('However, ...') and subordination ('Given that ..., ...')
    remain English-only.  Hedge is the dominant differentiator.
  - Hebrew/Greek grammar / word order unchanged.

Suite status: cognition 121, teaching 17, runtime 19, formation 182,
smoke 67 — all green.  Identity + safety + divergence suites: 26+15+15+15=71
all green.

Architecture Decision Records

This directory contains the Architecture Decision Records (ADRs) for the CORE project.

ADRs record significant architectural decisions: what was decided, why, what alternatives were considered, and what consequences follow. They are permanent records — superseded ADRs are archived, not deleted.

ADR-0024 chain — Forward Semantic Control closure

ADR-0022 through ADR-0026 form a single coherent chain that closes forward semantic control as a non-stochastic, replay-deterministic, trace-evidenced mechanism. Read in order:

  1. ADR-0022 — Forward Semantic Control. Establishes the AdmissibilityRegion data structure (allowed indices, relation blade, frame versor) and the contract that a region restricts the admissible token set at generation time.
  2. ADR-0023 — Proof Evidence. Boundary-only proof that the admissibility region is honored at the region intersection level but not yet at the destination-token level.
  3. ADR-0024 — Inner-Loop Per-Rotor Admissibility. Adds the destination-side check: each per-step selection is re-evaluated by cga_inner(versor(candidate), relation_blade) > threshold, with honest refusal (InnerLoopExhaustion) when every admissible candidate is rejected. Six phases of implementation evidence (Phases 1-6) plus typed RefusalReason taxonomy.
  4. ADR-0025 — Rotor / Frame Admissibility. Adds the rotor-side check: when a region carries a frame_versor, the rotor's effect on the field state (versor_apply(V, F)) is additionally checked against the frame for positivity in CGA inner product. Lives in generate/rotor_admissibility.py — a sibling-but-separate module, not in algebra/versor.py (would couple algebra to pack state) and not in field/propagate.py (forbidden normalization site).
  5. ADR-0026 — Ranked Admissibility with Margin. Replaces static threshold tuning with a scale-invariant margin gate: admit iff the top blade-score exceeds the second by ≥ δ. Defaults to δ = 0.4. Falsifiable; characterization documented in docs/evals/phase5_stratified_findings.md.

Implementation evidence:
