The 0.35 pin's rationale ("the post-0.35 rewrite is not yet production
quality") expired when iroh hit 1.0 in June 2026: the rewrite line
(0.103) is now the production line and the only one receiving fixes.
The rewrite replaced wrappable store traits with an irpc-based API, so
the seams moved:
- shaped.rs: the 440-line ShapedStore trait wrapper becomes a provider
event handler. Trust gating (untrusted peers see only openly-served
hashes) now intercepts requests before any bytes move; upload rate
limiting rides the provider's Throttle hook; upload progress events
come from per-request update streams. The TokenBucket is unchanged.
- store.rs: FsStore's API handle replaces the store traits, and the
LocalPool machinery for non-Send futures is gone. GC is now the
store's built-in periodic mark-and-sweep, fed by a pin-roots snapshot
via the protect callback (new config knob gc_interval_secs, default
300); the on-demand Gc request answers Unimplemented, and the gc
conformance test polls the sweep instead.
- transfer.rs: BlobsProtocol + Router replace handle_connection, the
new multi-provider Downloader replaces the old queue, and mdns
discovery moved to the iroh-mdns-address-lookup crate (it left iroh
core in 1.0). Ticket-embedded provider addresses feed a MemoryLookup
address book. Endpoint presets: Minimal (LAN-only default) or N0
(wan_upload), preserving the old relay posture.
- Node* became Endpoint* throughout; announcement signatures use iroh's
own Signature type (ed25519-dalek dep dropped); iroh-io dropped.
Known regression: max_download_bytes_per_sec is currently not enforced
— download shaping rode the old store's batch writer and 0.103's
downloader has no equivalent seam yet.
Announcement wire format note: EndpointAddr serializes differently than
NodeAddr, so pre- and post-migration daemons won't parse each other's
LAN announcements. Announcements are live-only, nothing stored breaks.

The discovery module defines the seam: DiscoveryProvider (subscribe/
announce over 32-byte TopicKeys) and a signed Announcement carrying
root hash, ed25519 author, metadata and provider addresses. Signatures
cover a deterministic postcard encoding including the topic (no cross-
channel replay) and the provider identities (addresses stay refreshable
hints). LanDiscovery conforms to the trait — mdns sightings become
locally-authored announcements, one per pinned root — and the daemon's
auto-sync now runs entirely through it: verify, index unconditionally,
fetch only for trusted authors from allowlisted providers on already-
pinned incomplete roots. The milestone-4 real-mdns sync test passes
unchanged through the new path. Verification unit tests cover round
trip, tampered root, wrong topic, forged author, mismatched signing
key, and serde survival. docs/redoal-integration.md sketches the
gesture-topic gossip provider against this contract.
Also: fix a flaky hang in the socket-activation test (dup2(3,3) leaves
CLOEXEC set when the listener already sits on fd 3; parent's listener
copy masked daemon death), and give the test client a read-timeout hang
guard. Add a top-level README.
Dependencies: ed25519-dalek (Signature type; same implementation iroh
keys use), postcard (deterministic signed encoding, iroh's canonical
compact codec).
