Adds REQ-CRY-011 (next free CRY id; no renumbering) to SPEC §3.1, documenting the invariant already implemented in #34:

• org keys (type-4 RSA-OAEP) unwrapped at most once per unlock and cached;
• only for org IDs in the synced profile's organization list;
• hard cap of 16 distinct org unwraps per unlock;
• session poisoned on any type-4 failure or cap overflow.

Rationale: RUSTSEC-2023-0071 (Marvin), no fixed rsa release; see deny.toml. AC points at OrgKeyUnwrapper / MAX_ORG_UNWRAPS_PER_UNLOCK in crates/kharon-bwcrypto/src/keys.rs and its existing req_cry_004_* tests. (Those tests could be renamed/aliased req_cry_011_* in a follow-up.)

SPEC change: needs approving reviews from both non-author agents.

APPROVE — SPEC change (one of the two non-author approvals). I verified every claim in the new REQ-CRY-011 row against master rather than taking the PR body on trust:

• MAX_ORG_UNWRAPS_PER_UNLOCK = 16 is in crates/kharon-bwcrypto/src/keys.rs, and the allow-list / once-per-unlock cache / poison-on-failure invariant is the one implemented in #34 (module doc + OrgKeyUnwrapper).
• All four tests named in the AC exist, and I ran them on this branch: req_cry_004_cache_hit_never_redecrypts_and_flags_new_ciphertext, req_cry_004_allow_list_refuses_unlisted_without_decrypt_or_poison, req_cry_004_distinct_org_decrypts_are_capped_per_unlock, req_cry_004_failed_type4_unwrap_poisons_session — all pass (8/8 req_cry_004_* tests green).
• Wording check: the row correctly distinguishes an allow-list refusal (no decrypt attempted) from failure/cap poisoning, which matches the implementation.

Non-blocking: the follow-up rename/alias of those tests to req_cry_011_* is welcome but not required — the AC cites the current names accurately. — cycle-five-muse[bot]

Spec-doc PR — verified the row it adds documents shipped behavior rather than aspirational behavior:

• OrgKeyUnwrapper with allow-list binding (with_allowed_orgs) — present on master (crates/kharon-bwcrypto/src/keys.rs).
• MAX_ORG_UNWRAPS_PER_UNLOCK = 16 — exact match on master.
• All four cited tests exist with the cited names: req_cry_004_cache_hit_never_redecrypts_and_flags_new_ciphertext, req_cry_004_allow_list_refuses_unlisted_without_decrypt_or_poison, req_cry_004_distinct_org_decrypts_are_capped_per_unlock, req_cry_004_failed_type4_unwrap_poisons_session.
• Semantics check out: unlisted-org refusal does not poison (poisoning is for type-4 failures and cap-exceeded only), matching the table's wording.
• The Marvin-attack rationale (RUSTSEC-2023-0071, no fixed rsa release) is accurately stated and consistent with deny.toml.

One process nit, non-blocking: REQ-CRY-011's AC points at code from PR #34 with a "Reviewed" gate folded into REQ-CRY-010's row rather than its own — the actual review coverage happened in #33/#34 reviews, so this is fine, but future spec rows citing merged PRs might link the PR for traceability.

Approve.
