* master: end the post-mint allocation hold on the embedded reporter's clean inventory DeferAllocation armed a warmup-length hold whenever the leader minted a fresh topology id, and on weed server the hold ran the whole window: the embedded volume server's join kept refreshing the quiet evidence clock, so the two-pulse early release still cost the first write 10-15s on every fresh start. weed mini already releases on its single pinned reporter's first inventory, but pinning refuses outside volume servers, which weed server must keep admitting. Add a non-exclusive variant: the topology names one expected reporter whose first clean full inventory lifts the hold, while other reporters stay admitted and still feed prior-state evidence and the topology-id freeze. A single-master weed server points it at its embedded volume server — the one reporter guaranteed to arrive quickly; a veteran's heartbeat carries prior state and keeps the window through the regular checks, so a wiped -dir with surviving external volume servers still trips the freeze on first report. Restarted clusters are untouched: a recovered topology id means no mint and no hold.

For setups that start with exactly one filer the scan is already final: a single-master weed server and weed mini announce as soon as it completes. A late external filer still joins and replays through the normal path — the confirm window only ever caught peers arriving inside it, and the residual risk mirrors the accepted volume-side trade-off: an embedded filer announcing a few seconds earlier can own the lock ring while a surviving external filer's backlog is still on its way.

The peer refresh already identifies the leader during the wait, so cap the retry pause at a second once a leader is named; while no leader is known the same short retry applies until the first stream is confirmed, since an unregistered server has nothing else to do. Once the server was registered the pulse backoff is unchanged, so a lost leader still paces reconnects the way it did before.

Clearing the hold outright let a rebuilt master re-issue a volume id a reconnecting veteran still owned. Collapse the released hold to one heartbeat interval instead: late reporters land their evidence or a topology-id freeze inside the pulse, and a re-mint re-arms that pulse rather than the full warmup. The pinned single-reporter release (weed mini) still drops the hold outright, since no other reporter can be admitted.

Announcing on the scan let the embedded filer take lock-ring ownership and serve writes that a peer's replayed backlog could then overwrite. Only weed mini keeps the skip, where the embedded filer is the only member its dev cluster can have. The confirm window only delays the master listing for a fresh store; the filer serves while it runs.

Match the Go side, where time.Until of a past deadline just sleeps zero. Generated with [Devin](https://devin.ai) Co-Authored-By: Devin <158243242+devin-ai-integration[bot]@users.noreply.github.com> * volume: retry the seed list without a second pulse sleep (rust) The error path already slept its retry delay; an extra full pulse after losing the round delayed the next attempt past what Go's heartbeat() does, which paces retries only inside the per-master attempt. * master: keep a configured allocation hold shorter than the confirm pulse Once the embedded report lands, the collapsed hold replaced the configured deferral with a full pulse even when the operator set a shorter one, including zero (disabled). Cap at the pulse instead. * filer: end the empty-membership confirm early on a fresh-minted embedded master On a fresh single-master weed server the announce gate still held the filer for the full confirm window, so the master's lock ring stayed empty and the first write retried 'no lock server found' for ~7s on top of the collapsed allocation pulse. A fresh TopologyId mint proves the master's persisted state was empty, making the empty peer scan final; skip the rest of the confirm only then, and keep it whenever the master recovers a prior id. * filer: keep a short reconnect window on a fresh-minted embedded master A fresh TopologyId mint proves the master's persisted state was empty, not that no external filer survived its loss — one can still be mid-reconnect on its keepalive cycle when the confirm starts. Ending the empty-scan confirm on the first poll let the fresh filer register and serve routed reads before that peer was found and backfilled, so existing files could read as missing. The fresh-mint path now shortens the confirm to a few keepalive cycles instead of skipping it: a reconnecting filer still lands in time, while a genuinely fresh cluster announces after ~3s rather than ~10s. * volume: skip the heartbeat loop when no seed masters are configured An empty seed list made the outer loop spin with no await between passes and no path to observe the stop flag. A masterless volume server has nothing to register with, so the heartbeat exits after a warning. * volume: skip the heartbeat loop when no master addresses are given (rust) Mirrors the Go heartbeat: an empty seed list spun the outer loop with no await and no shutdown checks. Exit after a warning so library callers get the same behavior as the binary path that validates the list up front. * filer: re-check the fresh-mint hint on each confirm pass The topology id is minted after raft election, which can land after the empty-scan confirm has already started — a one-time check at entry missed the mint and held the full window. Evaluate the hint on every poll and shorten the confirm from the first observed mint, still capped by the normal confirm deadline. * master: mark a fresh topology mint only when the volume bound is zero Recovery restores the max volume id unconditionally but the topology id only when present, so an upgraded or partially rebuilt master can mint a new id while still holding prior volume state. Marking fresh there would let the embedded filer shortcut its peer confirm on a cluster that is not empty; only mark the mint fresh when no bound survived. * filer: drop the fresh-mint shortcut once a peer has been observed --------- Co-authored-by: Devin <158243242+devin-ai-integration[bot]@users.noreply.github.com>
