feat(net)!: resolve archive time ranges through a fill lookup - #7310
A Time(pts) range on an archive::Consumer broadcast now resolves from the archive's key listing, not only from the groups the consumer's cache holds. A start reaches the stored group containing pts, and an end stops just after it, however old.
Before this, the consumer's cache held little more than the newest group. A time start older than that resolved to the oldest cached group, and the history below it was never asked for.
moq-net
When the groups held can't place a time start, and the track has a track::Requests handler that serves its history (not a received copy), the reader queues a lookup. A lookup is a fill over 0..reach that carries the time unresolved in the new Fill::time() and owes no group. The handler accepts the group containing the time, or the oldest group when the time is older than all of them. The reader's range then starts there once that group's first frame is written.
"Can't place" covers two cases: the time is before every group with a known start, or the newest cached group starting at or before it is followed by a gap. The gap can be one left by eviction.
A span waiting on a lookup reads nothing. A track's end waits for the lookup to answer.
A lookup left unanswered falls back to the groups held. The span's time end then walks from the oldest group held, since nothing below it is asked for.
A lookup owes no group, so wanted() is None, is_wanted() is false, and dropping it records nothing. A handler that doesn't know about times (the session fetchers, moq-c, the ffi, transcode) drops it untouched, and the range falls back to what the cache says, as today.
A time end walks the history through ordinary group fills. On a track whose handler serves history, only drops count as gone: sequences below the feed's start, or ones the live feed delivered and the cache evicted, may still be in the history. A reader also treats the runs its own fills refused, or that it gave up, as gone (Seen). So the end settles one group past the one containing it, and a gap in the archive doesn't stall it.
On such a track, a time range counts the first-frame time of a group accepted unverified (filled below the eviction watermark) as its start. Expiry and the rewind check still ignore unverified starts.
moq-archive
The index keeps the first-frame pts of each object that starts a group. An object continuing a group is left out, since its first frame says nothing about where later groups start. A lookup searches newest first from the newest group-starting object at or before pts up to the next one after it, and picks the newest group starting at or before pts from the stored group timestamps.
When every group starts after pts, the lookup answers the oldest group stored whole, skipping an oldest object's continuation whose head was pruned.
Impact
Public API: track::Fill::time() -> Option<Timestamp> is new. Wire: none.
Breaking (behavior): a Requests handler can now be given a lookup fill. It names the run 0..reach but owes none of it. A handler that serves start()..end() directly, instead of following wanted(), must skip any fill whose time() is Some, or answer it with the one group containing that time. Handlers that follow wanted(), which is every handler in this repo, need no change.
On a non-received track with a handler, a time start the cache can't place waits one handler round trip before it reads, even when the handler can't resolve times.
Decisions
Taken 2026-10-31, overnight, on the maintainer's standing authorization:
Unverified starts count for time ranges on history-served tracks (option 1). A group filled below the track's eviction watermark is accepted unverified and had no start, so a time range over an evicted span read [5, 4, 6, 7, 8] instead of [5, 6]. For time ranges only, and only on tracks whose history a local handler serves (not received copies, so every writer is local), an unverified group's first-frame time now counts as its start. Expiry and rewind checks are unchanged, which keeps the trust model against a remote publisher lying.
Lookup failures keep the documented fallback. A failed GET or a malformed object during a lookup leaves the lookup unanswered, so the range falls back to the cache, as Fill::time() documents, with a warning. Reporting the failure to readers needs new API: a lookup refusal, and a choice of whether a subscription fails, retries, or reports it. That choice is left as a follow-up rather than made here. Ordinary group fills still refuse a failed or malformed object with StreamError::Internal.
Taken 2026-11-01, merging main after moq-dev/moq#7036 removed Fill::unused()/poll_unused()/is_used() and renamed next() to wanted():
✅ Drop lookup cancellation; no new moq-net API. moq-archive used fill.unused() to stop a slow store read once nobody waited on a lookup. A lookup owes no group, so unwanted(sequence) can't stand in, and nothing public says when its readers leave. An abandoned lookup now finishes its store read and answers nobody. Group fills still stop on unwanted(sequence).
Alternatives not taken: make Fill::withdrawn() public (today poll_withdrawn is crate-private), or have time() turn None once the lookup is withdrawn.
Cost: wasted reads on slow stores when time-range readers churn. Listed under follow-ups.
Choices made without asking
Only the start goes in the fill. The end is not carried. It walks the history group by group through ordinary fills, which reuses the existing time-end walk and needs no second answer path. The cost is one fill per group across the range, and the archive's object cache absorbs most of the GETs.
Lookups never join or get joined by other fills. A lookup owes no group, so it can't answer another reader's run, and two readers with different times can't share one.
Only non-received tracks look up. A received copy's handler is its session, which fetches by group only. Its behavior is unchanged.
resolve_subscription now returns Unsupported while a start is still being looked up. This only happens on a non-received track whose handler serves history. Before, it resolved such a start to the oldest cached group.
No ffi or JS mirror of Fill::time(). Neither has a consumer for it yet, so it stays out of the bindings.
Tests
moq-archive, in-memory store: a start and an end older than the newest group; a start in a cache gap left by an earlier reader; a time older than the oldest stored object; a time older than an archive whose oldest object continues a pruned group (a_time_before_a_pruned_head_starts_at_the_oldest_whole_group); a time in a gap the archive never stored; a continuation object timestamped past the group it then starts (a_continuation_does_not_bound_a_group_start); a completed archive (the end waits on the lookup); an untimed track refusing a time range.
moq-net: a lookup a handler drops falls back with nothing asked below the oldest group; a looked-up range waits for the answered group to start, walks the history, and stops after its end; a time end walks evicted arrivals through the history (a_time_end_walks_evicted_arrivals_through_the_history); window unit tests for when a start is looked up, including an evicted gap, for when it is not, and for a time end settling after an unanswered lookup (an_unanswered_lookup_settles_a_time_end).
Each new test fails with its fix reverted.
just check origin/main passes on dd73c21 (after merging main).
On 4ac5799 (main 88e6990 merged): cargo nextest run -p moq-net -p moq-archive --tests --all-features under clippy with warnings denied passes (3304 tests), as do cargo clippy --workspace --all-targets, cargo fmt --check, and quest check.
Follow-ups
Cancel an abandoned lookup's store reads, if wasted reads on slow stores matter. Needs a public withdrawal signal on Fill (see the 2026-11-01 decision).
Report a lookup's store or decode failure to its readers, instead of falling back to the cache. This needs a lookup refusal in Fill and a choice of how a subscription surfaces it.
Mirror Fill::time() in moq-ffi and the bindings once a binding-side archive or DVR handler needs it.
A time end on a long historical range costs one fill round trip per group. If DVR rewind needs faster seeks, the end could be looked up as well.
Unverified starts are indexed when a group's first frame arrives, using whether a handler serves history at that moment. A handler registered later doesn't re-index groups that already started.

No new local review for head 4ac5799. The changes since the last reviewed head (dd73c21) are the land fixer's recorded mechanical fix, below, and a conflict-free merge of origin/main (88e6990). The guide exempts both.
Land ejection on 2026-11-01 (failed_checks): moq_clock unresolved in rs/moq-net/tests/integration/fastest_reader.rs. That file isn't on main or on this branch. It comes from moq-dev/moq#7388, which the same batch ejected with the same error. Nothing in this PR caused it, so only main was merged.
mechanical fix by codex / Codex: Merged base and mechanically preserved both sides of the three Rust conflicts; format checks pass; tests blocked by uncached offline uniffi dependency. (head aed225f)
Reviewer: Codex (quest review), gpt-6.1-sol, medium effort. Session 01a195a4, round 2 reviewed head dd73c21 with no findings.
Round 1, head dd73c21 (main merged, cancellation dropped):
Cancel archive lookups when their readers withdraw. Refuted by the 2026-11-01 decision above: no new moq-net API, and Fill::poll_withdrawn is crate-private (rs/moq-net/src/model/track/fill.rs:824). Follow-up.
Propagate storage failures instead of abandoning the lookup. Refuted by the 2026-10-31 decision above and the Fill::time() contract. Follow-up.
Earlier session 01a1914c (rounds 1–2, heads 746417a to 94cdc3a): an unanswered lookup stalling a time end, and the oldest-group fallback answering a pruned head, were fixed; failure propagation refuted as above.
Earlier session 01a18c22 (rounds 1–3, heads 210cb27 to 253787d): EOF ignoring a pending lookup, a cache gap skipping the lookup, and evicted arrivals hiding history were each fixed.
Online review threads: the continuation-timestamp thread is fixed by indexing only group-starting objects (a_continuation_does_not_bound_a_group_start). The evicted-arrivals thread is fixed by the history-served gone() and the unverified-start decision (a_time_end_walks_evicted_arrivals_through_the_history).
Closes nothing on GitHub; it completes quest/m2/archive-time-ranges.md, which this PR deletes along with its links.
… a fill
The archive consumer answers the lookup from its key listing, so a Time(pts)
range on an archive broadcast reaches the stored group containing pts, and a
time end stops just after it, however old.

Walkthrough
Time-anchored subscription ranges can request unresolved starts from fill handlers. The archive consumer indexes object timestamps and searches stored groups to resolve time-based starts and ends. Tests cover historical ranges, gaps, pruned objects, live-edge reads, and untimed-track errors. Quest entries and the proposed archive time-range document were removed.
Merge Risk: Moderate · up to b3af0
Some historical time ranges may start at the wrong group, and concurrent reads may stall. Resolve these issues before merging unless their risks are explicitly accepted.

Two P2 correctness issues remain: the archive index can choose an older group when a continuation object's first-frame timestamp exceeds a later group's start (inline), and I independently confirm the evicted-arrival time-end issue already reported in #7310 (comment); no duplicate inline for that finding.
Direction: reusing fills for archive lookup is a focused design, with explicit behavioral compatibility and useful completed-archive/cache-gap tests. Before relying on historical range boundaries, index group-start semantics rather than assuming all object-first timestamps are ordered, and keep evicted history unresolved until its timestamps or handler refusals establish the end.
GitHub-only static review of the changes and surrounding producer, window, fill, and archive code. No tests, benchmarks, or object-store operations were run; reported CI results were not independently verified.
…ivals
An archive lookup took the object whose key's first frame was at or before the
time, but a continuation object's first frame is a mid-group frame that bounds
no later group start. Index only objects starting a group, and search back
from the next one past the time for the newest group starting at or before it.
A time end walking history a handler serves took the live feed's evicted (or
grace-folded) arrivals as gone, so it settled past groups that start after the
end. On such a track only drops and a reader's own refusals count as gone.
WIP: a_time_end_walks_evicted_arrivals_through_the_history still fails. A fill
below the eviction watermark is Origin::Unverified, so its start is None and
neither the lookup answer nor the end walk can place it; fixing that needs a
decision on whether unverified starts count for time anchors.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
…erved track
A fill below the eviction watermark is accepted unverified, so it had no start: a
time range over an evicted span could neither place the group its lookup
answered nor walk its end through the history, reading [5, 4, 6, 7, 8] rather
than [5, 6]. On a track whose history a local handler serves, every writer is
local, so a time range counts an unverified group's first frame as its start.
Expiry and the rewind check still ignore it, so a remote publisher's unverified
start still bounds nothing.
a_looked_up_time_range_reads_the_history now holds the answer's first frame
back, so it checks the reader waits for the looked-up group to start rather
than placing the range from the cache alone.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
…pruned heads
A lookup a handler drops leaves its span starting before the oldest group held,
asking nothing below it, but the time end walked from group 0. On a track whose
history a handler serves nothing there counts as gone, so the end waited on
group 0 forever. It now walks from where the span reaches.
An archive lookup older than every stored group answered the oldest object's
first group even when the object continues a group whose head was pruned, which
can't be served from its first frame, so the lookup went unanswered. It skips
that group for the oldest one stored whole.

Automated review by review (OpenAI)
Reviewed commit: 94cdc3a, compared with my previous review at e54ba43 (same base).
Both previous P2 findings are addressed: the continuation-timestamp lookup now searches group-start candidates rather than excluding objects by continuation timestamps; the evicted-arrival time end keeps history unresolved and uses filled first-frame timestamps on local history-served tracks. The added tests cover those scenarios, delayed first frames, unanswered lookups and pruned heads. No new actionable bugs found in this update.
Direction: the fixes preserve the focused fill-based design without another lookup protocol. Restricting unverified starts to time anchors on local history-served tracks keeps expiry and remote rewind trust unchanged; retaining the existing group-by-group end walk is simpler than introducing a second answer path. Lookup-failure fallback remains an explicit limitation, not a newly introduced finding in this round.
Verification: GitHub-only static review of the three new commits and relevant archive, track and window code. No tests, benchmarks or object-store operations run; the reported local checks were not independently verified.

Use the latest sequence as the suffix lookup bound.
When unresolved finds no later indexed start, it returns None. TrackState::next_start searches only the starts index. A finished history-backed track can evict later groups while an older group remains; latest-group protection applies only while the track is live. The range can therefore resolve to the older group and skip an archive lookup for the suffix.
place already receives latest. Pass it to unresolved, and use latest + 1 as the lookup reach only when no later start is indexed. Add a regression test with an older held start and a newer latest sequence absent from starts.

quest land watch: the merge queue removed this pull request at 4ac5799 because it conflicts with main (merge_conflict).
The land fixer works on it in the background, and the watcher re-enqueues it at the back of the queue once it is fixed or judged flaky, or hands it back here with what it needs.
Merged base, retaining the PR time-lookup state and lookup-before-probe ordering alongside base stale-group accounting and consolidated fill locking. Build, formatting, all 3,333 nextest tests, and doc tests passed. The initial cargo test --locked -p moq-net -p moq-archive run hit setup::tests::credentials_stay_out_of_traces: Could not set global tracing subscriber: SetGlobalDefaultError("a global default trace dispatcher has already been set"). The test passed under nextest process isolation; no source change was made for this test-harness collision.
quest land watch: armed auto-merge on this pull request at b3af034, so it joins the back of the merge queue once its required checks pass, with the land fixer's fix (codex / Codex): Merged base and re·solved track.rs conflicts preserving both sides; passed cargo build --locked -p moq-net -p moq-archive; cargo nextest run --locked -p moq-net -p moq-archive; cargo test --locked -p moq-net -p moq-archive --doc; cargo fmt --check -p moq-net -p moq-archive..
Avoid taking the fills lock while holding the track guard.
TrackState::looks_up reads self.fills while next_held, gone, and index_start operate under the track state guard. Fetching::poll can retain a fills guard while it calls state.read().holds_datagram(sequence). These opposite lock orders can deadlock when the operations run concurrently.
Cache handler presence in TrackState, and update it when handlers are added or removed. Then looks_up can read the cached state without acquiring fills.

Update TrackState::looks_up to read cached handler-presence state instead of
acquiring the fills lock. Keep that cache synchronized whenever handlers are
added or removed, preserving the existing lookup behavior without introducing an
opposite lock order.

…nges/fill-linear
Conflicts:
- rs/moq-net/Cargo.toml: keep both the `ranges` and main's `backing` bench.
- lite/publisher.rs: main's `.parked()` subscription with this branch's
`groups` binding.
- track.rs probe: this branch's layered `retain` with main's single-lock
`(asks, fills)` judgement.
- subscription/window.rs: main's time-start lookups (#7310) ported
onto the shared and parked walks. A span looking up its start sits in a
`looking` list, outside the walks and runs, so `lookups()` costs the
lookups rather than every span. `found` places it as a fixed run or a new
walk, which walks from where the span reaches as main's did.
Integration fixes the merge exposed:
- Main's per-reader holdings (a reader's own refused and given-up fills count
as gone) collided with `window::Seen`; renamed `ReaderHoldings`. It now
reports what the reader's fills newly gave up as changes
(`Misses::take_gone`), so a time end parked on a gap its fill refuses
wakes. Every window walk reads it, including a replaced window, a pending
one, and a lookup's answer, so none parks on a gap already gone.
- A handler appearing or leaving (`looks_up`) wakes every parked walk, since
it changes which starts count and what is gone.
- miss.rs tests: main's `bound` and this branch's `view` both join `judge`.
New test: a_time_end_parked_on_a_gap_wakes_when_its_fill_refuses_it.

Summary
A
Time(pts)range on anarchive::Consumerbroadcast now resolves from the archive's key listing, not only from the groups the consumer's cache holds. A start reaches the stored group containingpts, and an end stops just after it, however old.Before this, the consumer's cache held little more than the newest group. A time start older than that resolved to the oldest cached group, and the history below it was never asked for.
moq-net
track::Requestshandler that serves its history (not a received copy), the reader queues a lookup. A lookup is a fill over0..reachthat carries the time unresolved in the newFill::time()and owes no group. The handler accepts the group containing the time, or the oldest group when the time is older than all of them. The reader's range then starts there once that group's first frame is written.wanted()isNone,is_wanted()is false, and dropping it records nothing. A handler that doesn't know about times (the session fetchers, moq-c, the ffi, transcode) drops it untouched, and the range falls back to what the cache says, as today.Seen). So the end settles one group past the one containing it, and a gap in the archive doesn't stall it.moq-archive
ptsup to the next one after it, and picks the newest group starting at or beforeptsfrom the stored group timestamps.pts, the lookup answers the oldest group stored whole, skipping an oldest object's continuation whose head was pruned.Impact
track::Fill::time() -> Option<Timestamp>is new. Wire: none.Requestshandler can now be given a lookup fill. It names the run0..reachbut owes none of it. A handler that servesstart()..end()directly, instead of followingwanted(), must skip any fill whosetime()isSome, or answer it with the one group containing that time. Handlers that followwanted(), which is every handler in this repo, need no change.Decisions
Taken 2026-10-31, overnight, on the maintainer's standing authorization:
[5, 4, 6, 7, 8]instead of[5, 6]. For time ranges only, and only on tracks whose history a local handler serves (not received copies, so every writer is local), an unverified group's first-frame time now counts as its start. Expiry and rewind checks are unchanged, which keeps the trust model against a remote publisher lying.Fill::time()documents, with a warning. Reporting the failure to readers needs new API: a lookup refusal, and a choice of whether a subscription fails, retries, or reports it. That choice is left as a follow-up rather than made here. Ordinary group fills still refuse a failed or malformed object withStreamError::Internal.Taken 2026-11-01, merging main after moq-dev/moq#7036 removed
