Topology rework. The mesh's job is width; depth now comes from knowledge.
Slots:
- Local/Wide collapse into ONE mesh pool: 20 desktop / 15 mobile
- Temp referral slots +4..+10 ABOVE the cap (10 desktop / 4 mobile), carry no
knowledge exchange, graduate into a freed mesh slot or expire (5 min TTL),
never evict an established mesh peer
- Fixes the Wide-never-fills bug: outbound paths hardcoded Local while the
growth gate counted Local only, so growth stopped at 71 and 20 slots were
inbound-only. Also closes register_connection paths that enforced no cap.
Knowledge — two-pool uniques announce (replaces N1/N2/N3 share lists):
- Pool 1 (forwardable): our N0-N2 uniques, deduped. Receiver stores shifted one
bounce deeper as N1-N3, reporter-tagged.
- Pool 2 (terminal): our N3, deduped against pool 1. Receiver stores as N4,
USED for search/resolution but NEVER re-announced. No N5 anywhere.
- Uniques merge mesh peers + social directs + CDN file authors + holder peers,
so receivers cannot tell how we know an ID
- Anchor entries carry addresses; every other entry is a bare ID. The pools
double as the anchor directory.
- Dedup at both store and announce; per-bounce caps; 2 MB payload ceiling
- Device-tiered depth: mobile holds 3 bounces and drops the terminal pool
Anchor convection (register loop retired — 0xC0 AnchorRegister deleted):
- Rolling in-memory caller window (no registration DB): a caller gets the 2
most recent viable prior callers, its address goes to the next 2, then
rotates out; still-connected callers preferred; RelayIntroduce coordinated
when both ends are live
- Request classes: entry (<2 connections) always served; top-up refused
cheaply under load, and the refusal feeds the adaptive weights
- Stochastic per-disconnect action {nothing | anchor intro | mesh intro} with
weights from local anchor density + refusal feedback. No thresholds, no
jitter timer. Recovery (mesh < 2) stays immediate and non-stochastic.
- Anchors mined from the uniques pools incl. retained pools of disconnected
peers; known_anchors demoted to a bootstrap cache
Security fixes from review: remote address poisoning (hearsay anchors could be
dialled — known_anchors/is_anchor now written only from completed handshakes),
N4 leaking back into announcements via the anchor mirror (infinite propagation),
missing payload size caps, unbounded candidate scoring, and a bulk SQLite write
held under the ConnectionManager mutex.
deploy.sh: version regex now captures pre-release suffixes (0.8.0-alpha would
have truncated to 0.8.0 and broken every artifact path), announce channel
derives from the suffix, and the anchor runs --publish-registry at genesis.
228 core tests; a3 integration 9/9; new c_topology_test.sh 33/33 (both
independently re-run). EDM corpse, session-relay gating, Iteration A/B intact.

A1 — ID-class bug family (v0.6.1 persona split left network-NodeId comparisons
where posting IDs live). ~14 sites fixed with multi-persona semantics ("author is
one of MY posting identities", not == default):
- revoke_post_access / revoke_circle_access (revocation was broken for every post)
- group key create/add-member/rotate (add-member distribution now works)
- circle profile set/delete/get, encrypted-attachment CEK unwrap
- receipt/comment slot authorship, replication cycle, blob eviction own-tier
- orphaned GroupKeyRequest/Response (0xA1/0xA2) deleted (no send side existed)
A2 — Manifest privacy: AuthorManifest.author_addresses removed from struct AND
signature digest; CdnManifest tree-era fields dropped. Startup migrations re-sign
own manifests, purge unverifiable foreign copies, strip persona fields from legacy
network-id profile rows. Posting identities are now location-anonymous.
A3 — Discovery & first contact:
- Open-slot comments: derivable slot V_x (blake3 from author + slot_binder_nonce)
so strangers pass the CDN comment-verification gate; OpenSlotDecl in FoF gating
- Greetings: HPKE-style sealed GreetingBody (return_path + fresh reply_pubkey),
throwaway outer ID, size-bucketed; messaging-first (Reply/Dismiss, no vouch)
- Registry: frozen canonical registry post + REGISTRY_POST_ID, signed registration
comments (self-certifying deletes), newest-wins per persona, --publish-registry
- Comment TTL: expires_at_ms inside signed digest v2 (context bump), rand 30-365d
ordinary / fixed 30d registrations, expiry sweep on the eviction cycle
- Single accept_incoming_comment() gate wired into all three ingest sites, closing
a pre-existing hole where both pull paths stored comments with no verification
- UI: consent panel (visible/listed/greetings, active choice at first publish),
registry search in Discover, sealed "Say hi" compose, greetings inbox
Security fixes from review: forged-tombstone injection, delete-by-sender-trust,
remote SetPolicy poisoning, stored XSS (escapeHtml quotes, 7 pre-existing sites),
greeting off-switch now revokes prior bios' slots.
No PoW (rejected: inverted cost). Session-relay gating untouched.
201 core tests pass; CLI + desktop build; 3-node integration green.
DEPLOY GATE: wire-incompatible with v0.7.3 — ALPN bump to itsgoin/4 lands in
Iteration B. Do not build/deploy/anchor-swap before that.
