Nothing answered check.requested, and plugins couldn't run.
Plugin dispatch.origin <name> replaces itself with origin-<name> from PATH when <name> isn't a built-in. Run inside a working copy, it records the working copy's draft first and sets ORIGIN_REPOSITORY, ORIGIN_REVISION and ORIGIN_REMOTE.
apps/origin-ci, the first plugin:
Checks. It reads checks.toml: each check's command, inputs, toolchain and whether it's external. origin ci run uses the revision's own file. The worker uses the one at the tip of the target being landed on, never the candidate's, so a change can't redefine the checks that guard its target. Every check runs in a fresh checkout and its own process group.
Results. It issues a ci.<name> statement whose inputs are the check's paths, always including checks.toml. Editing a check therefore reruns it. A result the worker ran with the target's checks on a candidate that edits checks.toml is declared external, so it's never promoted to what has the new checks.
Skipping. It asks the server to promote existing results first, and skips a check that's already covered.
Tool mode:origin ci run [<rev>] checks a revision as the user.
Worker mode:origin ci worker --remote <url> long-polls check.requested with a scoped token.
It reconciles the waiting landings at start, after an outage, and every minute.
It outlives server restarts, so no check is lost.
Its sweep only kills a process group it can prove still holds its run's lock. On macOS no such proof is possible, so it leaks the group rather than risk killing the wrong one.
Core changes:
Resuming waiting landings. A waiting landing now resumes when statements about its subject arrive, when promote runs, and when the server starts. A landing whose submitter's token has expired waits to be landed again.
origin annotate goes through the service, so it resumes landings too.
POST /promote is new.
Target landings can be checked: the merged snapshot of a waiting target landing can be fetched.
origin repo create --admin <principal> gives a server repository a remote admin.
Known limitations:
A change in a toolchain's output only reaches the queue's promotions through the inputs, so pin toolchains in an input file such as rust-toolchain.toml.
Ctrl-C in origin ci run doesn't reach the checks, which run in their own process groups.
Benchmarks: the worker adds about 11 ms per check on top of the command itself. Answering a check that's already covered takes 0.7 ms.
Review fixes: two tests now pass on macOS. The plugin test compares canonical paths. The cleanup test asserts kills only where the platform can see a process group (Processes::SEES_HELD_FILES). Both changes only matter on macOS, and the macOS CI job now passes. just passes on Linux (332 tests).

origin ci exec:origin ci exec <name> [--rev <rev>] [--inputs ...] [--toolchain <cmd>] [--external] -- <command...> runs an ad-hoc check exactly as ci run runs one of checks.toml: in a checkout of the revision, with its output as the payload, its exit status as the verdict and its command as the definition. It always runs, superseding your previous result of that kind. The runner also drops promotions a result on the revision replaces, through the same rule as the server.

A result stands for the checks in force on its target (#19). A worker runs a candidate's checks as the target's checks.toml defines them, but promotion matched results by the candidate's own copy. A candidate restoring an older checks.toml could therefore pick up a result run under the old definition. A check's inputs now have a second list, target_paths, read from the state of the target the subject is on (its base acceptance, down any stack) rather than from its own tree, and workers declare checks.toml there. origin ci run keeps the revision's own copy, which is what it runs with. Results from one target never counted for another already, through target_of and InvalidPromotion::OtherTarget.
Format break:Inputs gains a field, so every statement that declares inputs gets a new encoding and id, and the spec and digest contexts move to 2026-11. Nothing is released, so no migration.
Behaviour change: a candidate that only edits checks.toml now has the target's result promoted, since the worker would run the same definition on the same files.
Cost:input_digest on snapshot paths only takes 38.6 µs; with a target path on a revision three deep in a stack, 62.9 µs. That's the four record reads down to the base acceptance, paid once per statement when digests are computed.
Proof:results_stand_for_the_checks_in_force_on_the_target (end to end), target_paths_are_read_from_the_base and target_paths_are_read_from_the_target, each failing without the change, and just (366 tests).
Follow-up:origin ci run declares the candidate's own checks.toml, so if it runs under the worker's identity its results still count as the worker's. That predates this change.

This change adds external command plugins to origin, introduces the origin-ci tool and worker, and updates the service and repository APIs to support CI evidence and waiting landings. The pull request changes 49 files, with 4,612 lines added and 261 removed.
Plugin dispatch and repository context
When a command is not built in, origin looks for an origin-<command> executable on PATH and passes it the remaining arguments.
When the command runs in a working copy, origin records the current revision and passes the plugin the repository path, revision, and optional remote through ORIGIN_REPOSITORY, ORIGIN_REVISION, and ORIGIN_REMOTE.
The plugin runs without repository context when no working copy is available.
CI tool and worker
The new apps/origin-ci package provides origin ci run, origin ci exec, and origin ci worker.
run executes checks from checks.toml for a selected revision. exec runs a named ad hoc check.
Checks run in fresh checkouts. Their declared inputs include the selected paths and command digest; configured toolchain output also contributes to the check inputs.
The runner records pass or fail statements as ci.<name> results. It can reuse covered results, promote eligible results, and identify results as external when the check definition does not come from the subject’s snapshot.
The worker polls for check.requested events and reconciles waiting landings at startup, after event-stream recovery, and periodically.
A state-directory lock prevents multiple workers from using the same state. Process cleanup uses checkout locks to verify ownership before stopping a process group. On macOS, the platform cannot detect held files, so cleanup can leave a process group running rather than risk stopping an unrelated group.
Evidence, promotion, and landing flow
The service retries evidence-blocked landings when relevant statements arrive, after promotion, and when a repository opens.
Waiting landings retain submitter identity and token expiry. Retries use the stored submitter permissions and stop after the token expires.
Target-landing checks apply to a merge revision based on the destination target’s tip.
Promotion is restricted to records on the same target with matching input digests. The new POST /api/v1/repos/{repo}/promote endpoint returns promoted statements and can trigger retries for waiting landings.
The service can provide the merged snapshot for a waiting target landing to the CI worker.
CLI, repository policy, and supporting changes
origin repo create accepts --admin <principal> to assign an administrator in the initial repository policy.
origin annotate publishes through the service so new evidence can resume waiting landings.
The change updates client APIs, OpenAPI documentation, platform process support, test helpers, and benchmarks for the new behavior.
Reported limitations
Changes to toolchain output affect promotion through declared inputs. Toolchains should be pinned in an input file.
Ctrl-C in origin ci run does not reach checks running in separate process groups.
Verification
CI, build, and test results: not available from completed checks on the current head.

Walkthrough
The PR adds an origin-ci plugin with a runner and worker, an external plugin mechanism, and process-group support in the platform crate. It also adds a promote endpoint with target-scoped promotion, submitter-aware retries of waiting landings, an --admin option for repository creation, and documentation updates.
Changes: CI plugin, promotion, and landing retry
Layer / File(s)
Summary
Process-group platform support crates/origin-platform/*, Cargo.toml
Adds the Processes trait with group_holds, kill_group, and inherit. Linux scans /proc. macOS reports no held files. Conformance tests cover the new behavior.
Adds the plugin module and an external origin-<command> subcommand. Adds Workspace::plugin_context, Remote::open_for, Node::of, and the --admin option with the new Policy::initial argument. Test helpers and benchmarks are updated.
Target-scoped promotion and promote API apps/origin-src/src/annotations/*, http.rs, crates/origin-client/src/lib.rs, crates/origin-shared/src/api.rs, apps/origin-src/tests/http.rs
Promotion applies only to records on the same target. Adds PromoteRequest, the POST promote route, the client method, and service and workspace promote paths. Tests and benchmarks write acceptances.
Waiting landings store the submitter and scope expiry. Target merges use a revision as the evidence subject. The service retries evidence-blocked landings. Pending gains expires. Tests cover these cases.
origin-ci package apps/origin-ci/*
Adds checks parsing, per-repository state and checkouts, the runner, the worker, the origin ci CLI, a benchmark, and end-to-end tests.
Documentation and OpenAPI AGENTS.md, README.md, docs/*
Documents plugins, CI commands, promotion scope, retry expiry, and the promote endpoint.
sourceorigin-dev/origin#12: Adds statements, input digests, and promotion. This PR uses them for CI results and extends promotion to the same target.
Suggested labels:area/landing
Merge Risk: Moderate · previous review de5b3
The CI worker can stall when a check leaves background processes behind, so CI results stop being answered until the worker is restarted. Existing repositories that hold waiting landings written by the earlier format may also fail to list landings or start the server. Fix both before relying on this in shared setups.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
A failure to read the waiting landings fails a put_records call whose records are already stored.
resume returns an error when Queue::waiting cannot read or decode a queue file. One example is a StoreError::Malformed from a single bad file. push runs self.resume(Some(&subjects))? after the records are written and the push lock is dropped. In that case the caller receives an error although the objects are durable.
The retry is a best-effort follow-up. The resume documentation says a failed retry "leaves the landing as it was, and is logged". The read failure should follow the same rule.
If one queue file stays unreadable, every put_records call that carries a statement fails. This covers origin annotate and CI result puts. promote has the same problem at Line 1028. Repositories::open in server.rs also fails at startup because of the same resume_waiting error.
Log the error in push and promote, and return success. Keep the hard failure only where it is intended.
Proposed fix for `push`
- self.resume(Some(&subjects))?;+ if let Err(error) = self.resume(Some(&subjects)) {+ tracing::warn!(+ error = %anyhow::Error::from(error),+ "cannot retry the waiting landings"+ );+ }

Bound the wait for the output pipe after the shell exits.
On macOS, a background process can retain stdout after checkout.stop returns. On Linux, a process that leaves the group can do the same. output.join() then waits until that process closes the pipe, blocking the single worker from answering other requests.
Return an error if output collection cannot finish in a bounded time. Do not issue a result with incomplete toolchain output.

A check can fail to start, the worker can stop working, or the check command can fail to write the file. In any of these cases, the test hangs forever instead of failing.

Waiting files written before this change now fail to decode, and one bad file breaks every queue listing.
PendingFile::decode now requires a by <principal|owner> line right after subject. The header origin pending 1 did not change. A file from the earlier format has missing … or conflict … on that line. decode returns None, and Queue::waiting turns that into StoreError::Malformed.
Queue::waiting aborts on the first such file. Every caller of Queue::waiting or Queue::pending then fails. That includes land --status, the landings API, event derivation for check.requested, and OriginService::resume at startup. One legacy waiting file in an existing repository is enough.
Do not default a missing by line to owner. A landing submitted by a remote caller would then retry with owner rights.
Instead, bump HEADER to origin pending 2. Make Queue::waiting skip files with an older header and log a warning. Update the "origin pending 2\n" assertion in pending_landings_round_trip to use a different invalid header.
If no repository holds waiting files from the earlier format yet, state that in the PR and ignore this comment.

Qualify the Linux process-cleanup guarantee.
If a check starts a process that leaves its process group, Linux cleanup does not kill that process. The unconditional claim can lead operators to rely on cleanup while a check's background process continues running. State that cleanup covers processes still in the check's identifiable group.

origin <name> now runs origin-<name> from PATH when <name> isn't a
built-in, replacing the process so stdio and exit codes pass through.
In a working copy, which it snapshots first, it passes the plugin
ORIGIN_REPOSITORY (the store's directory), ORIGIN_REVISION (the working
copy's revision) and ORIGIN_REMOTE.
apps/origin-ci is the first plugin. It reads checks.toml from the
revision under test (command, inputs, toolchain, external), runs each
check in a fresh checkout of its own in its state directory, removed
afterwards, and issues a ci.<name> statement whose inputs are the
check's paths, the command's digest and the toolchain output's digest,
with the end of its output as an attachment payload. checks.toml is
always among the inputs, read from where the checks are in force: the
revision, for `origin ci run`, and for a worker, which runs the checks
of the target landed on, a target path. Inputs gains target_paths, read
from the state of the target the record is on (its base acceptance's,
through a stack), which the input digest and its spec cover, so a
result stands for the definition it ran under: a candidate that
restores an older checks.toml doesn't match the results of the older
checks, and one that only edits it still matches those of the checks in
force. A result of the same issuer declaring the same inputs,
ran or promoted, skips the run. `origin ci run [<rev>]` checks a
revision of the local repository as the user. `origin ci worker --remote
<url>` long-polls check.requested with a scoped token. It also
reconciles: when it starts, once the remote is back after going away,
and every minute, it answers every check a waiting landing lacks that it
hasn't answered, so a missed event, a restart or a failed run loses no
check. It waits for a remote it can't reach instead of exiting. It talks
to origin only through Remote: the SDK, or the in-process service for a
local path.
The queue now continues when evidence arrives: waiting landings record
their submitter, and putting statements about a waiting landing's
subject retries it for them, under the policy in force; `origin
annotate` puts its statement through OriginService for that. OriginService
gains promote (POST /promote), so a plugin can carry results over
before running a check, from what the caller sees, and fetching the
merged snapshot of a waiting target landing, so target-onto-target
landings can be checked. `origin repo create --admin <principal>` gives
a new server repository an admin who changes its policy over the API.
Like `origin`, `origin-ci` ends quietly once its output pipe is closed.

origin <name>replaces itself withorigin-<name>fromPATHwhen<name>isn't a built-in. Run inside a working copy, it records the working copy's draft first and setsORIGIN_REPOSITORY,ORIGIN_REVISIONandORIGIN_REMOTE.apps/origin-ci, the first plugin:checks.toml: each check's command, inputs, toolchain and whether it's external.origin ci runuses the revision's own file. The worker uses the one at the tip of the target being landed on, never the candidate's, so a change can't redefine the checks that guard its target. Every check runs in a fresh checkout and its own process group.ci.<name>statement whose inputs are the check's paths, always includingchecks.toml. Editing a check therefore reruns it. A result the worker ran with the target's checks on a candidate that editschecks.tomlis declared external, so it's never promoted to what has the new checks.origin ci run [<rev>]checks a revision as the user.origin ci worker --remote <url>long-pollscheck.requestedwith a scoped token.Core changes:

rust-toolchain.toml.origin ci rundoesn't reach the checks, which run in their own process groups.Benchmarks: the worker adds about 11 ms per check on top of the command itself. Answering a check that's already covered takes 0.7 ms.
Review fixes: two tests now pass on macOS. The plugin test compares canonical paths. The cleanup test asserts kills only where the platform can see a process group (
Processes::SEES_HELD_FILES). Both changes only matter on macOS, and the macOS CI job now passes.justpasses on Linux (332 tests).Reviewed with review-loop: 2 rounds with 2× GPT-6.1 Sol and Claude Opus 5.5. Verdict: approved
origin ci exec:origin ci exec <name> [--rev <rev>] [--inputs ...] [--toolchain <cmd>] [--external] -- <command...>runs an ad-hoc check exactly asci runruns one ofchecks.toml: in a checkout of the revision, with its output as the payload, its exit status as the verdict and its command as the definition. It always runs, superseding your previous result of that kind. The runner also drops promotions a result on the revision replaces, through the same rule as the server.

A result stands for the checks in force on its target (#19). A worker runs a candidate's checks as the target's
checks.tomldefines them, but promotion matched results by the candidate's own copy. A candidate restoring an olderchecks.tomlcould therefore pick up a result run under the old definition. A check's inputs now have a second list,target_paths, read from the state of the target the subject is on (its base acceptance, down any stack) rather than from its own tree, and workers declarechecks.tomlthere.origin ci runkeeps the revision's own copy, which is what it runs with. Results from one target never counted for another already, throughtarget_ofandInvalidPromotion::OtherTarget.Inputsgains a field, so every statement that declares inputs gets a new encoding and id, and the spec and digest contexts move to2026-11. Nothing is released, so no migration.checks.tomlnow has the target's result promoted, since the worker would run the same definition on the same files.input_digeston snapshot paths only takes 38.6 µs; with a target path on a revision three deep in a stack, 62.9 µs. That's the four record reads down to the base acceptance, paid once per statement when digests are computed.results_stand_for_the_checks_in_force_on_the_target(end to end),target_paths_are_read_from_the_baseandtarget_paths_are_read_from_the_target, each failing without the change, andjust(366 tests).origin ci rundeclares the candidate's ownchecks.toml, so if it runs under the worker's identity its results still count as the worker's. That predates this change.Reviewed with review-loop: 1 round with 2× GPT-6.1 Sol and Claude Opus 5.5. Verdict: approved
