Finishes quest/m2/no-sentinels.md (deleted here): no public type uses a huge value or zero to mean "none" or "unbounded".

Summary

• Receive window. moq_net::transport::ReceiveWindow.connection is Option<NonZeroU64> (None: streams share no connection window, as the memory transport reports). ReceiveWindow::new takes the Option. moq-quic's Connection::receive_window() (QUIC and qmux) returns NonZeroU64, since its windows come from non-zero Limits, so a zero can't be configured and the drivers never reinterpret one. Pause accounting (boxed::Shared::reserve) caps paused credit at half the window when there is one; without one, a paused stream reserves nothing.
• Cache ceiling. origin::Config.cache_duration, broadcast::Info.cache_duration, and moq_relay::cache::Cache.duration are Option<Duration>; None (the default) is no ceiling. Duration::MAX is gone as a marker, and a ceiling that doesn't lower an unbounded demand leaves it unbounded, so Some(Duration::MAX) behaves like None on the wire.
• Reconnect. reconnect::Config.timeout, Backoff.timeout, and Backoff.max are Option<Duration>. moq-tokio's config layer still reads a configured 0 as "off" (its text/FFI/C knobs are tri-state: unset = default, 0 = off, value) and converts to None where it builds the policy. js/net's ReloadDelay.max and .timeout take null for no bound (undefined still means the default), the same spelling as a subscription's delay.max. In both languages zero is a real bound: a zero timeout still makes the first attempt and gives up when it fails, and a zero max retries at once. The window is checked where a retry's wait ends, not where a walk starts, so the first dial of a run, a healthy migration, and a restart's redial always happen, and a late timer or poll (a sleeping device) gives up instead of dialing past the window.
• Relay workers. runtime.workers is a Workers enum: "shared" (the default), "auto" (one per core this process may use, capped at moq_sock::shard::MAX_SHARDS, via the new moq_tokio::worker::Config::auto()), or a count. 0 is refused instead of meaning "shared", and a value of the wrong type names the accepted ones.
• FFI test clock. moq_ffi_test_clock_now(uint64_t *nanos) -> bool returns false without a clock instead of u64::MAX; the Python Clock.time() raises then.

The aligned backoff default: retry forever

The Rust backoff timeout defaulted to 10 s and JS to unlimited. Both now default to no give-up (None / null):

• A reconnect loop exists to ride out outages. js/net already argued this: a page has nothing that redials it once the loop gives up. A native app (moq-ffi on mobile, OBS) or a long-lived moq CLI publisher is in the same position.
• moq-gst already overrode the 10 s default to unlimited for both elements.
• Failure stays visible without giving up: each failed attempt reports Retrying/status, and a caller that can act on a persistent failure sets a timeout.

The one caller that relied on the finite default was the relay's cluster peer client, whose inner loop must give up so the redial loop moves to a fresh UDP port and re-reads cluster.token. It now sets that bound itself (PEER_RETRY, 10 s, the old value) when the template leaves it unset or zero, so relay behavior is unchanged.

Impact

Breaking (public API; no wire change):

• moq-net: ReceiveWindow { connection: Option<NonZeroU64> } and ReceiveWindow::new(Option<NonZeroU64>, u64). origin::Config.cache_duration and broadcast::Info.cache_duration are Option<Duration>. reconnect::Config.timeout, reconnect::Backoff.{max,timeout} are Option<Duration>; Backoff::default().timeout is None (was 10 s).
  • Migrate: wrap a value in Some(..). Replace u64::MAX/Duration::MAX/Duration::ZERO-as-unbounded with None. A transport reporting a QUIC window passes Some(conn.receive_window()).
• moq-quic: Connection::receive_window() returns NonZeroU64 (call .get() for the old u64).
• moq-tokio: --connect-backoff-timeout unset now retries forever (was 10 s); set it to keep a bound. New worker::Config::auto().
• moq-relay: cache::Cache.duration: Option<Duration>. runtime.workers / --runtime-workers / MOQ_RUNTIME_WORKERS take shared, auto, or a positive count; workers = 0 is refused (use "shared" or omit it). config::runtime::Config.workers is runtime::Workers.
• @moq/net: Connection.Backoff (ReloadDelay) max/timeout are Milli | null; null means no bound. A zero now means zero: timeout: 0 gives up when the first attempt fails and max: 0 retries at once (migrate 0 to null); both are documented and tested.
• moq-ffi (testing feature only): moq_ffi_test_clock_now takes an out-pointer and returns bool.
• Bindings and C keep their config conventions (null/has_* = default, 0 = off). Only the documented default changes: "no give-up" instead of "a 10s window".

Choices made without asking

• Backoff default: retry forever (above), with the relay's peer clients pinned to their old 10 s.
• moq-tokio's config layer keeps 0 = off. Its CLI/TOML/env/FFI/C knobs need three states, and absence already means "default". The Backoff::max()/timeout() accessors still return Duration with zero = off, matching that layer. The sentinel is gone from moq-net, where the policy lives. Reworking moq-tokio's whole config surface is the follow-up below.
• The JS change is null absence only. ConnectProps.timeout (one dial's bound) still uses 0 = no bound; js-time-types will retype JS durations.
• auto lives in moq-tokio (worker::Config::auto()), because moq-relay depends on moq-sock only under its io_uring feature.

Overlaps

Open PRs touching the same files, with small mechanical conflicts only: moq-dev/moq#8247 (moq-relay/src/cache.rs), moq-dev/moq#8253 and moq-dev/moq#8220 (moq-ffi/src/test.rs, untouched here), moq-dev/moq#8248 (the moq-tokio/moq-uring QUIC drivers, one line each). The concurrent no-credit-hook quest edits stream_credit beside receive_window in the transports.

Suggested follow-ups

• Plan: moq-tokio's config layer reports "off" as zero through its resolved values (connect::Resolved.timeout, connection::Backoff::{max,timeout}(), Goaway.handover, quic idle timeout). Give the resolved/accessor side Option while the text knobs keep 0 = off.
• Drop: the Go wrapper's RetryForever = -1 is now the default. It stays useful as an explicit spelling, and removing it would break callers for no gain.

Walkthrough

The changes update retry defaults and timing in JavaScript and Rust, including checks that prevent attempts after a retry deadline. They replace sentinel values with optional cache durations and connection receive windows, and change the test-clock FFI to return status separately from elapsed time. Relay worker configuration now supports shared, automatic, and explicit-count modes. Documentation and tests are updated for these changes.

Merge Risk: Low · up to 1d386

The changes retain narrow edge-case risks involving unbounded transport credit, maximum cache durations, and configuration diagnostics. These warrant bounded owner awareness or follow-up; native zero-valued retry settings retain their documented behavior.

Explanation

The title "feat!: public API uses Option, not a huge value or zero, for 'none'" matches the main change. The PR replaces sentinel values such as u64::MAX, Duration::MAX, and zero with Option or null across moq-net, moq-relay, moq-tokio, moq-quic, the JS net package, and the FFI test clock. The title is specific and concise. It omits the relay worker enum and the backoff default change, but the title does not need to cover every detail.

Full details: Description check

Explanation

The description is specific and on-topic. It names the removed quest document and the changed public types: moq-net ReceiveWindow, cache_duration fields, and reconnect Backoff/Config timeouts. It also covers the relay runtime.workers enum, the JS ReloadDelay null semantics, the FFI test clock change, the new default of no give-up for reconnect backoff, and the migration notes. It matches the changeset in the raw summary and the PR objectives.

Automated review by review (OpenAI)

Reviewed head bf8a90f. No actionable findings.

The optional receive window and cache ceiling propagate consistently through their consumers, and QUIC/qmux retain nonzero window invariants. Reconnect policies distinguish absence from zero, with the configuration adapters retaining their documented zero-as-off convention. The relay explicitly keeps the ephemeral-port retry window at 10 seconds despite the new unlimited default. Worker-mode parsing and the FFI/Python clock signature are aligned.

Direction: retain explicit absence at the policy layer and keep configuration conversion at the boundary. Verification limits: GitHub source/diff review only; no builds, tests, binding generation or runtime checks performed.

[pullfrog]

ℹ️ No critical issues — one stale comment and one undocumented zero, both minor.

Reviewed changes

• Receive window: transport::ReceiveWindow.connection is Option<NonZeroU64>, and pace::window / boxed::Shared::reserve only apply the half-window cap when a connection window exists; the QUIC and qmux drivers report Some while the memory transport reports None.
• Cache ceiling: origin::Config, broadcast::Info, and moq_relay::cache::Cache take Option<Duration>, with None as "no ceiling" threaded through track::TrackState.
• Reconnect: Config.timeout and Backoff.{max,timeout} are Option<Duration>, and the give-up logic was refactored around Option without changing the bounded or uncapped paths. The default retry window is now no give-up.
• Relay workers: runtime::Workers {"shared" | "auto" | count} refuses 0, auto() sizes from available_parallelism capped at MAX_SHARDS, and the ephemeral cluster dial keeps its 10 s bound.
• JS backoff: ReloadDelay.{max,timeout} take null for no bound, while 0 now means a real zero.
• FFI test clock: moq_ffi_test_clock_now writes through an out-pointer and returns false without a clock; Python raises.

Verified in this run: cargo check --release --all-targets for moq-relay, moq-tokio, and moq-ffi is clean; js/net's reload and pool tests pass (78 tests) and bunx tsc --noEmit -p net/tsconfig.json is clean.

ℹ️ The cluster redirect-loop guard still promises a give-up

Backoff::timeout now defaults to None, so a configured cluster peer's reconnect loop never exhausts. That makes the comment at rs/moq-relay/src/cluster.rs:2232-2234 — "escalates through backoff and eventually gives up instead of migrating forever" — untrue: an A↔B redirect loop now escalates and retries indefinitely. Only the ephemeral dial is pinned via EPHEMERAL_RETRY.

Technical details

# Cluster redirect loops no longer exhaust

## Affected sites
- `rs/moq-relay/src/cluster.rs:2232-2234` — comment claims the retry window ends an A↔B redirect loop.
- `rs/moq-relay/src/cluster.rs:2276-2282` — `EPHEMERAL_RETRY` bounds only `ephemeral` clients; a non-ephemeral peer keeps `backoff.timeout = None`.
- `rs/moq-net/src/reconnect.rs:763` — redirect (non-restart) pacing uses `self.config.backoff.timeout`, now `None` by default.

## Required outcome
- Either update the comment to match the new unbounded behavior, or give configured peers a finite window so the documented guard still holds.

## Open question for the human
- Is indefinite retry acceptable for a configured peer stuck in a redirect loop, or should `peer_client` set a bound for non-ephemeral dials too?

Reviewed changes (delta since the prior pullfrog review: merge of origin/main, only rs/moq-relay/src/cluster.rs changes)

• PEER_RETRY now bounds every peer client: renamed from EPHEMERAL_RETRY and moved out of the ephemeral branch, so a template whose connect.backoff.timeout is unset or zero gets the old 10 s bound for configured peers as well. That keeps the redirect-loop give-up described at cluster.rs:2282-2284 true and leaves the outer redial loop (the only re-reader of cluster.token) to take over.

This resolves the retry-window concern raised against the previous head; nothing else in the merge needed a change.

Automated review by review (OpenAI)

Reviewed 7be2da2 incrementally, accounting for merged main changes.

P2: Recheck the retry deadline when resuming a walk (rs/moq-net/src/reconnect.rs:525–531). Resume::Walk is selected using the remaining window when back_off schedules the wait, but poll can resume later than that window. For example, a retry scheduled for 10 ms under a 100 ms window still returns a new Dial when polled at 200 ms. Removing the check from start means this extra walk can connect successfully after the give-up deadline, or wait for another full attempt timeout, contrary to the documented no-new-walk guarantee. Preserve the first-walk/Restart exception for a zero window, but retain and recheck the applicable absolute deadline before resuming an ordinary retry. Add a regression that polls after both the scheduled wake and retry deadline.

The zero-window first-dial behavior is now covered for both success and failure, and the JS zero-bound documentation/tests are explicit. Verification limits: GitHub-only static diff/source review; no tests or builds run. GitHub currently reports merge conflicts, so post-resolution integration is unverified.

[pullfrog]

ℹ️ No critical issues in the new commits. The zero-window fix is correct and covered, and the JS zero semantics are now documented and tested.

Reviewed changes (delta since the prior pullfrog review: 89806a5, 1296de2f0, 7be2da283, plus a merge of main that left the PR's files unchanged)

• A zero retry window now makes its first walk: Phase::Start no longer checks the window; back_off decides between Resume::{Walk,Restart,GiveUp} and gives up exactly at the deadline, so Some(Duration::ZERO) dials once and reports Exhausted instead of never dialing.
• New Rust coverage: a_zero_timeout_gives_up_when_the_first_walk_fails asserts the single dial, the immediate Exhausted, and that a serving peer is still accepted under a zero window.
• JS zero semantics documented and tested: ReloadDelay.max and .timeout TSDoc now state what zero does, and the windows/backoffs tables add timeout: 0 and max: 0 cases.

Verified at 7be2da2: cargo test -p moq-net --lib --all-features reconnect::tests (23 pass) and bun test src/connection/reload.test.ts (46 pass).

Not approving this head only because your own review still lists rs/moq-net/src/reconnect.rs:527 ("Recheck the retry deadline when resuming a walk") as open: with the window check moved into back_off, a poll that wakes past the deadline starts one more walk instead of giving up. Nothing new from this pass.

Automated review by review (OpenAI)

Reviewed 9551e92 incrementally from 7be2da2. The prior P2 late-wake retry-deadline finding is fixed in the current code.

Rust now checks elapsed time when an ordinary retry wait actually ends, before another walk starts, while keeping the initial-walk and restart exceptions. The JS retry timer also rechecks its captured deadline before advancing the dial tick. Both added regressions explicitly resume past the retry window and assert exhaustion without another dial.

No new actionable findings in this four-file update. Verification limits: GitHub-only static source/diff review; tests and builds were not run.

[pullfrog]

✅ No new issues found.

Reviewed changes (delta since the prior pullfrog review: 9551e92)

• Rust checks the retry window when the wait ends: Phase::Backoff now carries { until, restart } instead of a Resume enum. A non-restart backoff re-checks backoff.timeout against retry.start before starting another walk, so a poll that lands past the deadline reports Exhausted rather than dialing past it, while the first walk, a healthy migration, and a restart's redial still always dial.
• JS retry timer rechecks its deadline: #retry captures #deadline (extracting the give-up closure) and the timer that fires the wait gives up when now() >= deadline, matching the Rust behavior for a late timer after the device slept.
• Regression coverage: a_late_poll_past_the_window_gives_up polls 2 s into a 1 s window and asserts Exhausted; retry window: a backoff that fires past the window gives up uses Manual.jump to fire the timer late and asserts one dial plus ConnectTimeout.

Verified at 9551e92: cargo test -p moq-net --lib --features async reconnect:: (36 pass) and bun test net/src/connection/reload.test.ts -t "retry window" (4 pass), with bunx tsc --noEmit -p net/tsconfig.json clean.

This resolves the late-wake retry-deadline finding; nothing else in the delta needed a change.

Automated review by review (OpenAI)

Reviewed head 0e0ee05 incrementally against the latest published review, accounting for merged main changes.

No new actionable findings. An ineffective cache ceiling now preserves an unbounded subscription instead of encoding Duration::MAX as a finite delay. Pausing without a shared connection window reserves zero credit, avoiding aggregate overflow while retaining per-stream pacing; resume/drop remain consistent. The relay worker-mode parsing diagnostics and CLI override regression match the explicit shared/auto/count API.

The prior P2 late-wake retry-deadline fix remains intact. Verification limits: GitHub-only static source/diff review; no builds or tests executed.

Reviewed changes (delta since the prior pullfrog review: 0e0ee056a plus 115309e93, a merge of main)

• A huge cache ceiling stays unbounded: clamp_combined now lowers the aggregate's delay.max only when the bound is actually smaller, so Some(Duration::MAX) no longer becomes an unencodable Some(Duration::MAX) on the request; a_huge_ceiling_keeps_an_unbounded_demand_unbounded covers it.
• Pauses reserve nothing without a connection window: boxed::Shared::reserve returns zero instead of charging window.stream to the shared counter, so the counter can't overflow or refuse later pauses, and every stream may still pause; the pause test extends to three streams on a connection: None window.
• Worker-mode parse errors name the choices: the untagged Workers input carries serde's expecting, with tests for -1 and 1.5, and the relay loader test proves --runtime-workers=auto overrides a TOML count.
• Merge keeps the Python clock change: main's relocation of the test clock is adapted to py/moq-rs/tests/clock.py, preserving the out-pointer/bool signature and the raise-without-clock behavior.

Reviewed statically (only target/release exists here, so a cold debug test build exceeds the shell cap); CI Check is still in progress on this head.
