docs: flip FoF section 20a badges to v0.7.0 + sessions.md release entry

design.html section 20a (Friend-of-Friend Visibility):
- Section header badge: planned → v0.7.0 complete
- FoFClosed PostVisibility table row: planned → v0.7.0
- All 5 layer rows in the implementation table: planned → v0.7.0
- Custom-subset row retained as v2 (genuinely deferred per spec)

sessions.md: full session entry for the Layer 1-5 implementation arc.
34 commits, ~24 new fof:: integration tests, key design decisions
preserved (slot_binder_nonce circularity fix, per-post pub_x/priv_x,
multi-epoch receiver-chain V_me storage, retroactive cascade delete,
key-burn semantics).

+## 2026-05-13 to 2026-05-15 — primary Claude (Lead) — `docs/fof-spec-layer1-bio-grants` → master
+
+**Started**: May 13 UTC. Released v0.7.0 stable on May 15 UTC.
+**Instance**: Scott's primary Claude (Lead)
+**Issue**: implement FoF spec Layers 1–5 end-to-end
+**Branch**: `docs/fof-spec-layer1-bio-grants` (continued from prior spec-drafting session; merged to master at d46fcb4 on May 15)
+**Scope**: Friend-of-Friend post gating: per-persona vouch keys, anonymous bio-post wrapper distribution, FoF-gated comments with CDN verification, FoF-closed encrypted bodies, V_me lifecycle (rotation/cascade/key-burn), unlock cache + retry sweep. Pre-deploy hardening pass. Version bump to 0.7.0 stable.
+
+**Commits landed on master** (34 total, `1fdf9a9..d46fcb4`):
+
+Layer 1 (vouch primitive):
+- `8a53d83` schema + storage API + HPKE-sealed vouch-grant crypto + 3 tests
+- `bc008c5` wire types (VouchGrantBatch) + V_me auto-gen on persona create
+- `3ee5c30` publish path: bucketed-padding VouchGrantBatch in bio posts
+- `d1afcec` receive-path scan + follow-gating + scan cache (2 e2e tests)
+- `34c5b60` Tauri commands + Settings UI for vouching
+
+Layer 2 (Mode 2 + CDN verify + revocation + access-grant):
+- `74fec3b` wrap-slot dual-derivation seal/open primitives + 4 tests
+- `0f5147a` wire types: WrapSlot, FoFCommentGating, CommentPermission::FriendsOfFriends, RevocationEntry
+- `bdcd214` fof.rs: build_fof_comment_gating with bucketed padding
+- `673f9e2` wired FoF gating into post-create path
+- `00522f4` reader unlock + commenter authoring + sig verify (1 roundtrip test)
+- `63ff5ad` CDN four-check verification on AddComment receive
+- `583033e` persist FoF fields + fof_revocations table
+- `6a76ade` FoFRevocation diff + sign/verify/apply + retroactive cascade-delete (2 tests)
+- `96118d7` FoFAccessGrant diff + retroactive read widening (1 test)
+- `10de3f6` Tauri commands + frontend compose-picker for Mode 2
+
+Layer 3 (Mode 1 FoFClosed):
+- `856f386` PostVisibility::FoFClosed variant + body encrypt/decrypt + body-size bucket padding (3 tests)
+- `66b7804` create_post_fof_closed + read_fof_closed_body + frontend hooks for locked/unlocked posts (1 e2e test)
+
+Layer 4 (V_me lifecycle + cascade + key-burn):
+- `c0de21d` own_post_slot_provenance + Node::rotate_v_me + cascade_revoke_v_me_epoch (1 test)
+- `c2f2203` FoFKeyBurn primitive (1 test)
+- `fdbf97f` supersedes_post_id field for re-issue path
+- `ce710a6` Tauri commands + Settings "Rotate my vouch key" UI
+
+Layer 5 (perf):
+- `12a3058` unlock cache + unreadable-posts queue + author-direct fast path + sweep on V_x arrival (2 tests)
+
+Pre-deploy hardening (audit pass):
+- `aa190db` wire-shape validation on incoming FoF posts; unreadable-queue per-persona cap of 4096 (7 tests)
+- `4ec3a80` key-burn replay rejection (monotonic timestamps); MAX_SWEEP_PER_CALL=256 (1 test)
+
+Release prep:
+- `d46fcb4` version bump 0.6.2 → 0.7.0; download page updated with FoF release notes
+
+**Test count**: 158 passing on master (added ~24 new fof:: integration tests across Layers 1–5 + hardening).
+
+**Build state**: full-pipeline deploy initiated on May 15 (`./deploy.sh` from this Linux host: CLI + AppImage + APK in parallel, sign APK, sequential SCP uploads, anchor swap with signed release announcement). Windows installer separate (uploaded by Windows host team).
+
+**Key design decisions worth knowing**:
+- `slot_binder_nonce` (32B random per post) replaces the spec's "post_id in HKDF info" — PostId = BLAKE3(post) was circular here. Same anti-replay property.
+- Per-V_x signing keypair (`pub_x`/`priv_x`) generated per-post (not per-V_x-genesis). Comment signing is asymmetric Ed25519; PQ-migration deferred. Body + comment-payload encryption is symmetric ChaCha20-Poly1305 (PQ-safe).
+- `vouch_keys_received` keyed by `(holder, owner, epoch)` — multi-epoch retention is the receiver-chain mechanism. New V_me from a voucher appends; old key isn't deleted.
+- Revocation is per-post per-pub_x with retroactive cascade-delete. V_me rotation is grandfather-by-default; cascade is opt-in via `cascade_revoke_v_me_epoch`. Key-burn swaps slots in-place for leaked-key scenarios.
+
+**Pending after deploy succeeds**:
+- Live shakedown on real devices (Scott has been looking forward to this).
+- Per-post Revoke / Grant Access UI surfaces (Tauri commands exist; only Rotate has a Settings button so far).
+- Update `MEMORY.md` "Current Status" to v0.7.0 once anchor swap confirms healthy.
+
+**Stopping point**: deploy script running in background; master at `d46fcb4`. Awaiting deploy completion notification.
