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).

Metered detection polls NetworkManager's Metered property over D-Bus
(feature "metered", default on; builds without D-Bus via
no-default-features). While metered the daemon closes incoming blob
connections and defers every fetch; VARDE_FORCE_METERED=true forces the
state as a kill switch and test hook. Endpoint UDP sockets get DSCP CS1
best-effort by matching bound ports to /proc/net/udp inodes (iroh hides
its fds). systemd socket activation adopts LISTEN_FDS fd 3, readiness
is a hand-rolled sd_notify READY=1 (abstract + path sockets), and
standalone binding still works unchanged. dist/ ships hardened system
and user units (DynamicUser, ProtectSystem=strict, StateDirectory,
RestrictAddressFamilies), a commented config example, scdoc man pages
validated with scdoc, and an untested PKGBUILD skeleton.
Tests: activation-socket round trip via a real fd-3 handoff, READY=1
received on a NOTIFY_SOCKET, metered daemons neither serve nor fetch.
Dependencies: zbus (optional, feature-gated D-Bus client for the
NetworkManager metered flag).

mDNS-style LAN discovery (iroh MdnsDiscovery, discovery flag, default
on) feeds a presence tracker; trusted peers that appear trigger fetches
of every incomplete pin, and Pin itself now fetches from present
trusted peers. Serving is our own ProtocolHandler: trusted NodeIds get
the full store, everyone else a filtered view limited to open_lan pins
and ticket-exported hashes (plus hashseq children) that answers "not
found" for the rest. Ticket export records standing serve-consent for
that hash; trust changes take effect on new connections. ShapedStore
implements the full iroh-blobs Store trait to charge provider reads to
an upload token bucket and downloader writes to a download bucket;
upload cap 0 closes incoming connections at accept. Subscribe now
streams transfer_progress both ways, peer_joined, and pin_complete.
Tests: forged-ticket trust gating (denied untrusted, served after
trust), 256 KiB/s upload cap enforced by wall clock, event stream
during a transfer, and real-mdns auto-sync between two daemons
(skips where multicast is unavailable).
Dependencies: n0-future, async-channel, futures-lite, bytes — all
already in the tree via iroh; needed directly to name types in
iroh-blobs trait signatures and channels. iroh feature
discovery-local-network for MdnsDiscovery.

The daemon binds an iroh endpoint (ed25519 identity at secret.key,
0600), serves its store via Blobs/Router on the standard ALPN, and
fetches with the iroh-blobs Downloader rather than the rpc client to
keep quic-rpc out of the tree. Relay is disabled unless wan_upload is
set: LAN-only, zero WAN upload by default. TicketImport pins first
(the pin is the GC root protecting in-flight data), registers the
ticket's NodeAddr with the endpoint (the downloader dials by NodeId
alone), then fetches in the background; completion emits pin_complete.
Tests: two-daemon localhost transfers (blob + directory collection,
byte-identical), and kill -9 mid-transfer followed by restart on the
same store resuming to completion.
Dependencies: iroh 0.35 (endpoint/router, pairs with iroh-blobs 0.35),
rand 0.8 (secret key generation, same version iroh uses).
