Decentralized social media network — no central server, user-owned data

Wires the access-grant primitive end-to-end:
Wire format:
- BlobHeaderDiffOp::FoFAccessGrant { post_id, new_pub_x,
new_wrap_slot, granted_at_ms, author_sig }. 64-byte Ed25519 sig
by post author over canonicalized tuple.
fof.rs:
- sign_fof_access_grant / verify_fof_access_grant: identical shape
to revocation but covers (pub_x, wrap_slot, granted_at).
- apply_fof_access_grant_locally: appends to local pub_post_set +
wrap_slots. Refuses to apply if new_pub_x is already revoked
(prevents accidental re-admission of a previously-blocked signer
per Layer 4 resolved decision). Idempotent on (post_id, new_pub_x).
storage.rs:
- append_fof_access_grant(post_id, new_pub_x, new_wrap_slot): mutates
the stored post's fof_gating_json column to append the new entry.
PostId (in id column) is unaffected — local-evolution semantics:
the stored gating diverges from the original t=0 snapshot as
access-grants and revocations land.
connection.rs: receive arm verifies author_sig + applies locally.
Author API (node.rs):
- Node::grant_fof_access(post_id, new_v_x): recovers the post's CEK
by trial-unwrapping the author's own slot (find_unlock_for_post),
generates a fresh per-V_x keypair, seals a new wrap slot under
new_v_x with the same CEK + slot_binder_nonce, signs the grant,
applies locally for immediate UI, then propagates via
propagate_engagement_diff.
New test brings the suite to 142 passing:
- fof_access_grant_appends_and_unlocks: pre-grant Carol cannot
unlock; Alice grants; post-grant Carol unlocks and recovers the
CEK; duplicate grant skipped; revoked pub_x cannot be re-admitted.
