Engineering unchanged. Adds a code-free reading layer mapping each Theory-of-Freedom component (axioms, ownership hierarchy, consent, divine justice, guidance, Mahdavi compass, conflict-by-clarification) to its file:line in src/, with an honest coverage matrix marking enforced vs. extension-only vs. documented gaps.

Companion to COVERAGE_MATRIX.md, adding the formal-artifact column it omits: the actual Lean theorem / Kani harness behind each axiom AND its true strength. Honest findings (no spin): - A4/A6 are Kani-proven (prop_ownerless_machine_blocked, prop_machine_governs_human_blocked); their Lean theorems are `True := trivial` stubs. - A5/A7 attenuation + epoch revocation are real Lean proofs. - forbidden-flag theorems are real but SHALLOW: they prove "flag set => Blocked" (enforcement of a declared flag), NOT detection of coercion/deception. - verify_deterministic is `:= rfl` (vacuous). - Consent is Python-only/partial and absent from the Rust TCB; Justice, Guidance, and the Mahdavi compass are extensions-only with no proofs. Conclusion stated plainly: AuthGate is a proven (narrow) Rights *Verification* Kernel; the book's Rights-based *Decision* Kernel (detect coercion; choose the most legitimate among permissible actions) is not built and has no formal content.

47 attack tests across the three Theory-to-Engineering gaps: - consent_redteam.rs (18): forged grantor keys, pubkey substitution, resource/rights swaps, consent-id forgery, revocation bypass, post-seal injection/reorder, documented L2 trust-root limit, permit<->valid invariant. - semantic_gate_redteam.rs (15): exit-block disguise, HHI boundary, case/ substring/unicode-homoglyph evasion (documented), NaN/negative shares, 50+ case totality sweep, advisory-never-denies. - compass/redteam.rs (14): score-gaming, NaN/Inf, zero/negative/huge weights, registry poisoning, and the safety proof that the Compass never denies. Full suite: 293 passed, 0 failed. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
…verage - Replace the misleading 'Python layer enforces the same logical invariants as the Rust TCB' claim with an honest 'compatibility runtime, not a security boundary; bypassable; only the Rust TCB carries guarantees'. - Add a Theory->Engineering coverage table for the three now-implemented axioms (A3 consent = TCB; A4/A5 semantic gate + A7 compass = advisory, NOT TCB), each with explicit trust level and no overclaim (notes the L2 owner-binding limit; calls the compass 'never denies' an asserted test, not a proof). - Update the verified Rust lib test count to 293 (incl. 47 red-team tests).

…ayer above) Explains why AuthGate (authority/enforcement, Rust TCB, crypto) and the Freedom Decision Kernel (legitimacy/decision, pure Python, no crypto) are separate sibling repos: legitimacy != authority. FDK decides whether an action is legitimate and hands the chosen action to AuthGate, which enforces whether the actor is authorized. Legitimacy first, then authority.

What & why
Closes the three open gaps in
Theory_to_Engineering_Plan.md, mapping axiomsA3/A4/A5/A7 of the Theory of Freedom (نظریه آزادی) from prose into Rust. Each
gap previously existed only as bypassable Python; this lands the parts that
belong in code, at the correct trust level — and nothing more.
Changes
src/tcb/consent.rs(+engine.rsLayer-4 gate,types.rsfields)src/semantic_gate.rssrc/compass/ConsentRecord(ed25519, identity-bound, expiry, revocable). When theadapter sets
requires_consent, noPermitissues without a valid, unexpired,unrevoked consent covering actor+resource+rights, folded into the binding hash.
SemanticGatetrait +CoercionAnalyzer(exit-blocking, HHI,deception markers). Returns a verdict; never structurally denies.
C(a) = w1*RVD + w2*VOI + w3*CDas a post-hoc scorer that annotates,never denies. The deny threshold is operator policy, not theory.
Honest scope (no overclaim)
that's the L2 trust-root boundary, out of scope by design (documented + tested).
