Closes the trust gap ADR-0027 opened: making the identity manifold
swappable was necessary for downstream robotics / personalization /
creative deployments, but it left nothing structurally preventing a
downstream identity pack from disabling core safety constraints.
Safety packs sit at a separate trust layer, fail closed on every error
path, and union their boundaries into every runtime manifold regardless
of which identity pack is selected.
Architecture (sibling to identity packs, structurally distinct):
Layer Swappable? Removable? Schema
--------------- ---------- ---------- -----------------------------
Safety pack No No boundary_ids + descriptions
Identity pack Yes No value_axes + surface_prefs
Language pack Yes (>=1 reqd) vocab / morphology / packs
Composition rule (at ChatRuntime startup, additive only):
identity = load_identity_manifold(config.identity_pack)
safety = load_safety_pack() # fail-closed
final.boundary_ids = identity.boundary_ids ∪ safety.boundary_ids
Safety contributes boundaries only — no value_axes, threshold, or
surface_preferences. This keeps existing tests that assert on identity
axis sets passing byte-for-byte, and matches the semantic intent
(safety is what's forbidden, not what's pulled toward).

Five v1 boundaries, each closing a specific CLAUDE.md doctrine:
no_fabricated_source — no invented provenance
no_hot_path_repair — no normalization in propagate/stream/store
no_identity_override — user text cannot mutate identity
no_silent_correction — failures are typed and visible
preserve_versor_closure — ||F * reverse(F) - 1||_F < 1e-6
Fail-closed semantics:
SafetyPackError inherits from RuntimeError (NOT ValueError) so
catch-and-continue is discouraged at the type level. Missing file /
malformed JSON / empty boundaries / duplicate boundary / failed
self-seal all raise. ChatRuntime.__init__ does not catch.

README.md §Safety Pack added
memory/safety-pack.md auto-memory entry
Suite status: cognition 121, teaching 17, runtime 19, formation 182,
smoke 67, identity 41, safety 15 — all green.
- Add docs/teaching_order.md as durable reference for curriculum ordering.
Five-layer rule (identity axes -> atomic definitions -> binary relations ->
composed relations -> domain expansion), grounded in ratify.py G3,
MasteredCoursesIndex, and exact CGA distance. Linked from README.md.
- Mark formation_pipeline_plan.md as IMPLEMENTED (back half); enumerate the
open items not closed by Phases 1-7 (additional templates, first formation-
routed curriculum, G2 activation).
- Add 2026-05-17 status block to capability_roadmap.md covering the FSC chain,
epistemic schema closure, formation pipeline back half, FSC v3 proof matrix,
cost benchmark, and the pulse import fix.
Patent-grade precision pass over the doc surface so every claim
about the Forward Semantic Control chain is backed by a file path,
test count, or commit hash.
Updates by file:
README.md
- Modernize Quick Start: add `core test --suite adr-0024`,
`core demo phase6 / phase5 / all / list-results`, full CLI map.
- New "Forward Semantic Control — The ADR-0024 Chain" section
with layer/ADR mapping and CI-enforced C1/C2/C3 claims table.
- Cross-links to runtime_contracts.md, phase5_stratified_findings,
phase6_comparative_demo, and the central results directory.
docs/decisions/README.md
- Index was stale at ADR-0014. Add ADR-0015 through ADR-0026
with accurate Accepted statuses.
- New "ADR-0024 chain — Forward Semantic Control closure" section
laying out the five-ADR / six-commit dependency order with test
counts per phase.
docs/runtime_contracts.md
- Add "Ranked-with-margin contract (ADR-0026 / Phase 3)" section
between the existing Phase 2 refusal and Phase 4 rotor sections.
- Documents threshold-mode vs margin-mode behaviour, δ = 0.4
default, falsifiability gate, and Cl(4,1) signature motivation.
docs/PROGRESS.md
- Add naming-note disambiguation: capability-roadmap "Phase N"
vs ADR-0024 chain "Phase N" are distinct.
- New top-of-document "ADR-0024 Chain — Forward Semantic Control
Closure" section with per-phase commit + test-count table and
a single-command verification path.
docs/Whitepaper.md
- New Section XII "Forward Semantic Control — Generation Without
Sampling" before Extensions. Five-component description of the
mechanism (region, intersection, destination check, rotor check,
margin gate) with explicit "what a sampling LLM cannot exhibit"
contrast. Existing Section XII renumbered to XIII.
docs/Yellowpaper.md
- New Section IX-B "Forward Semantic Control — Formal Admissibility
Specification" with eight subsections covering:
1. AdmissibilityRegion typed triple (I, B, Φ)
2. Destination-side admissibility (σ_dest, admit_threshold)
3. Rotor-side admissibility (σ_rotor, admit_rotor)
4. Ranked-with-margin gate (admit_margin, deterministic
tie-break by index, default δ = 0.4)
5. Honest refusal (InnerLoopExhaustion typed evidence,
RefusalReason enum, trace fold)
6. Composition order at the generation seam
(admit_step = intersection ∧ destination ∧ rotor)
7. Replay determinism contract (5 test lanes pinning byte
identity across reruns)
8. Verification invariants table (6 new structural contracts)
- Patent-grade: every predicate is named, every module is path-
referenced, every test is file-referenced, the load-bearing
architectural placement decision (rotor admissibility lives in
generate/, NOT algebra/, NOT field/) is stated by name with
its rejection reasoning.
No code changes; tests untouched (1099 passed, 2 skipped baseline
from commit 36aad75 still holds).
Audit of the one-mutation-path invariant (ADR-0021 §3) found three leaks
where pack authority or session-state writes could substitute for coherence
judgment. All three landed fixes or partial closures in this push.
Leaks closed:
- Leak A: pack vocab defaulted to COHERENT — flipped to SPECULATIVE in
language_packs/{compiler,schema}.py; docstring corrected to align with
ADR-0021 (it was rationalizing the leak).
- Leak B: vault.recall was epistemic-blind — VaultStore.store() now stamps
every entry with EpistemicStatus (default SPECULATIVE); recall(min_status=)
filters to admissible-as-evidence tier. All 4 vault-write sites updated.
- Leak C (write-side): generate/proposition.py:198 stored articulated
propositions unmarked — now stamps SPECULATIVE, breaking the
fabrication-feedback loop in principle. Read-side audit of 5 call sites
is the residual.
New architectural invariants (tests/test_architectural_invariants.py):
- INV-21: one-mutation-path allowlist (caught Leak C on first run)
- INV-22: pack lexicon default is SPECULATIVE (Leak A guard)
- INV-23: vault recall epistemic-aware (Leak B guard)
New eval lanes:
- teaching_injection_resistance — ships GREEN at 1.00/1.00/0 (the
structural anti-injection claim is real and measurable)
- refusal_calibration — honest gap: 0% refusal, 0% fabrication
- contradiction_detection — honest gap: 50% flag via versor-delta heuristic,
100% false-positive; motivates the proper coherence-checker
- articulation_of_status — honest gap: 0% speculative articulation, 60%
false certainty; output-side leak surface
New benchmarks:
- benchmarks/footprint.py — total deployed runtime is 7.06 MiB
(109,358x smaller than Llama 3.1 405B, runs offline, no GPU)
- benchmarks/learning_curve.py — monotonic + replay-deterministic curve
per lane
Documentation:
- docs/truth_seeking_schema.md — foundational architectural commitment,
five rules, mapped to human failure modes, leaks published openly
- evals/CLAIMS.md — five-tier public claims doc; Tier 4.5 publishes
known gaps with named fixes; verification contract at top
- README.md — new pillar between algebraic substrate and language pillar
Includes in-flight formation pipeline scaffolding (formation/, tests/formation/,
docs/formation_pipeline_plan.md) and minor CLI/contracts/gitignore edits
that were already in the working tree at session start.
Verification: 798 passed, 2 skipped, 1 deselected (pre-existing pack-count
test drift unrelated to schema changes).
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.
