fix(spawn): replay service caller invokes durably - #2119
Bind external service-caller spawns to Relaycast's durable, caller-scoped strict spawn claim instead of a bounded local receipt ledger.
Send external invokes only through the dedicated /v1/actions/spawn/strict-invoke route and require the server-owned spawn_contract_applied proof.
Recover already accepted work through replay-only /v1/actions/spawn/replay when the requested directory can no longer be safely materialized; the recovery path cannot create, place, or dispatch work.
Keep current harness and directory authorization on every attempt while allowing the authorized canonical worker_cwd to be rematerialized for the same stable logical request and idempotency key.
Preserve the legacy session-caller request bytes and target preflight. Existing session calls do not gain target_node_id, logical-request, or strict-contract fields.
This is the Relay client half of a paired change and requires Relaycast PR #644. Replay-capability strengthening remains stacked separately in #2142 with Relaycast #647.
Current exact head: 8258e208424b45f457bbb152ed014a54cbc72240. It normally merges current main 503020b94bc9d1acd065c6f37afc4aaa3fdfd461 into the reviewed feature tree. The only substantive conflict was the session-only target preflight: it now uses current-main workspace_http(workspace) and targets(workspace.kind(), ...), while external callers retain strict invoke/replay and return before that preflight. The #2133 Core Bridge compatibility split remains byte-identical to current main.
Verification
Literal fresh-install, Core Bridge, TypeScript, formatting, and 39-test Rust control evidence for the exact tree is captured in the exact-head verification comment.
Independent exact-head source review found no conflict-resolution defect. All hosted checks at this exact head completed successfully.
This is not a full Flows #707 or live Desktop E2E signoff. It does not merge or release Relaycast, Relay, Core Bridge, or Flows. The complete path still requires the paired server changes, reviewed human merges, official package release, the Flows pin, and live local/remote lifecycle acceptance.
It looks like this branch is under active development. To avoid overwhelming you with review comments due to an influx of new commits, CodeRabbit has automatically paused this review. You can configure this behavior by changing the reviews.auto_review.auto_pause_after_reviewed_commits setting.
External spawn calls now check caller scope and use Relaycast’s strict-invoke route with a logical request and idempotency key. Retries use Relaycast claims and replay rather than locally retained receipts. Session calls continue to use the existing invoke flow.
Changes: Service-caller invocation

Summary
Strict invocation and scope handling crates/relay-node/src/relay/spawn/control.rs, crates/relay-node/src/relay/spawn/control/tests/callers.rs
External calls check harness and directory scope, submit strict logical requests, and require the spawn-contract marker in the returned receipt. Session calls retain their existing invoke flow. Tests cover scope checks, request fields, and session-token use.
Durable claim retry and replay crates/relay-node/src/relay/spawn/control.rs, crates/relay-node/src/relay/spawn/control/claims.rs, crates/relay-node/src/relay/spawn/control/tests/callers.rs, CHANGELOG.md
The local unrecorded-receipt persistence path is removed. Tests cover retry after restart, directory revalidation, and replay after caller scope changes. The changelog records the invocation and retry behavior.
This change makes retries of external service-caller spawns durable by using Relaycast's strict claim and replay routes. The supplied evidence shows no concrete merge-blocking defect. It does depend on the paired Relaycast change being released, so coordinate that release before relying on it.

Exact-head repair evidence for c3f44dee8 (test-only successor to 27833de2a).
Hosted macOS arm64 failed because macOS resolved the checked directory through /private/var, while the test compared it to the equivalent /var spelling:
The regression now creates its own nested symlink on every Unix platform and compares the forwarded worker directory to the canonical checked directory. Reverting only the canonical expectation makes the strengthened regression fail:

This does not expand the source claim or close the production Desktop/live-E2E gate for Flows #707. Hosted macOS must rerun at this exact head.
Cross-repo merge blocker for the Flows #707 production acceptance path, found by exact-head read-only audit.
At this PR's current head c3f44dee8f6837177c75edc1c13e1f09a1a921e5, packages/core-bridge/src/auth.ts accepts caller files only when:
doc.auth==='challenge-hmac-sha256/v1'
The current Desktop service-caller candidate 6553a3538796daa575b2007678d8974117ddde4b writes the schema-v2 field from desktop-core/src/service_callers/handoff.rs as:
Therefore readCallerCredential() rejects every file written by that Desktop candidate. Please settle one canonical schema and add a shared/cross-repo fixture before treating the client as Desktop-compatible.
The same audit found two downstream contract gaps relevant to this package's public surface:
Flows fix: harden npm publish packaging #707 still sends raw caller_name / caller_secret, which this PR intentionally refuses; it has not yet adopted connection-bound challenge auth.
Desktop requires invocation-scoped spawn_callers.inbox.open({invocation_id}), while core-bridge currently exports authentication/spawn helpers but no typed identity/inbox/ack/fail/close/disconnect helpers. Without those, Flows would have to recreate the raw bridge contract.
This comment reports source compatibility only; it is not a test or release claim. Relaycast #644 and this PR remain draft, and no merge/publish is requested here.
The cross-repo caller-file mismatch now has a literal exact-head reproducer against c3f44dee8f6837177c75edc1c13e1f09a1a921e5.
I temporarily added this test to packages/core-bridge/src/auth.test.ts and restored the tracked source afterward (git diff --exit-code printed TRACKED_SOURCE_RESTORED):
it('accepts the actual Desktop schema-v2 auth route shape',()=>{constdesktopDocument=document({auth: {scheme: 'challenge-hmac-sha256/v1',challenge: 'spawn_callers.challenge',authenticate: 'spawn_callers.authenticate',},});expect(CallerCredential.fromDocument(desktopDocument).callerId).toBe(base.caller_id);});

This is a production acceptance blocker for Flows #707, not a theoretical format concern: Desktop's candidate writer emits the object above, while this reader accepts only the string. Please choose one canonical schema, share one fixture between producer and consumer, and add a mutation-sensitive compatibility regression before #2119 is treated as the released client contract. No Relay production source was changed by this diagnostic.
Independent execution of the prepared schema-v2 client candidate for the Flows #707 Desktop acceptance path.
This is not a claim about this PR's current c3f44dee8 head. I checked exact candidate 318c5447bb3dd5823d108205150b95e0814736d5 (review/flows-707-caller-schema-candidate), whose three commits add the object-auth parser, typed identity/invocation-inbox/settlement/disconnect surface, and secure caller descriptor reader on top of this PR. Snow's source reviews recommended adoption but could not execute the tests in its worktree.

## review/flows-707-caller-schema-candidate
The Desktop producer's current fixture still uses the canonical object route (auth.scheme, auth.challenge, auth.authenticate), so the existing PR head's string-only parser remains incompatible. The candidate is test/build clean, but still needs a normal rebase/adoption, exact-head review/CI, versioning and publication before it can satisfy Flows #707. No merge or release is requested by this comment.
Current public-package compatibility update for the Flows #707 chain:
@agent-relay/core-bridge@18.0.0 is now public from Relay main ee15d3dd, but it still lacks the full schema-v2 surface Flows #707 declares and calls. A fresh install is missing:
So rebasing only this PR's strict transport onto current main is not enough: the full schema-v2 descriptor/identity/inbox/settlement/disconnect candidate must also be adopted, tested against the actual Desktop fixture, versioned, and published before Flows can consume a public package. Please keep the compatibility work and strict replay work explicitly accounted for in the current-main successor. No package or source change was made by this comment.
[Medium impact] No blocking issue remains in the reviewed stack, with PR #2142 and the paired Relaycast changes required for deployment.

Shorten the entry and split it into one bullet per user-visible change.
The bullet joins two changes: the agent-relay-node service-caller spawn behavior and the @agent-relay/core-bridge credential and method checks. It also includes implementation detail ("neither path needs a second local lifetime ledger"). State the practical effect for each change instead.
📝 Proposed rewrite
-- Service-caller spawns bind the exact node ID and a strict logical request to Relaycast's durable invocation claim. Retries may rematerialize an authorized working directory, while a replay-only lookup recovers an accepted invocation when that directory is no longer safe to materialize; neither path needs a second local lifetime ledger. `@agent-relay/core-bridge` now accepts only schema-v2 challenge credentials and refuses a core missing any required service-caller method.+- `agent-relay-node` service-caller `spawn.invoke` calls bind the exact node ID and are retried durably through Relaycast. A retry recovers the accepted invocation even when the requested directory is no longer in the caller's scope.+- `@agent-relay/core-bridge` accepts only schema-v2 challenge credentials and refuses a core that lacks any required service-caller method.

Independent exact-head check at c35859cff192215c6b2d2d581b3bbbf80f96a1aa.
The first local Cargo invocation failed before opening the fake Relaycast socket because this host's Cargo test process injects file-selected certificate roots, which relay-node intentionally rejects:
$ TMPDIR=/home/khaliqgant/.cache/relay-2119-rust-tmp cargo test --manifest-path crates/relay-node/Cargo.toml 'a_retry_after_restart_replays_the_exact_request_without_rechecking_the_target' -- --nocapture
SSL_CERT_FILE = Some("/etc/ssl/cert.pem")
SSL_CERT_DIR = Some("/etc/ssl/certs")
InvalidResponse("Platform certificate file overrides are not supported")
test relay::spawn::control::tests::callers::a_retry_after_restart_replays_the_exact_request_without_rechecking_the_target ... FAILED
Those diagnostics were temporary and were removed; git status --short and git diff --check were then empty. Running the exact built test binary under the intended platform-trust environment passes:
$ env -u SSL_CERT_FILE -u SSL_CERT_DIR TMPDIR=/home/khaliqgant/.cache/relay-2119-rust-tmp crates/relay-node/target/debug/deps/agent_relay_node-0e80f58e8ac12e9f --exact relay::spawn::control::tests::callers::a_retry_after_restart_replays_the_exact_request_without_rechecking_the_target --nocapture

test result: ok. 1 passed; 0 failed; 0 ignored; 0 measured; 2400 filtered out; finished in 0.03s
This check found no source defect in the restart replay case. The exact head's GitHub checks are green and both review threads are resolved. No merge, release, or branch mutation was performed.
Release-readiness correction after the latest cross-repo audit:
This exact client head remains source/CI clean, but the end-to-end release chain is not ready. Relaycast PR #646's current cb8814be97e106e18cc856035636fdce3c5a5272 is obsolete, conflicting, and has revoked signoff. Do not merge or release that head.
The remaining server gap is a narrow successor on Relaycast #644 exact f997fc8717bd4d62b40c5fea982824381dd69074: explicit opt-in replay-resume authority for a stored strict claim when the caller can no longer safely rematerialize local input. It must replay the original stored task/cwd under the same caller/key, never create/fallback, leave historical unmarked claims lookup-only/fail-closed, and retain the placement-token/dispatch-generation/unknown-send fencing already proven at f997fc.
After that server contract is independently reviewed, this client must verify the new server-owned replay-capability marker on its replay path before any public release or Flows #707 compatibility claim. The canonical crash acceptance must then prove one claim/reservation/frame/worker/result/release/cleanup across SIGKILL plus raced restarts.
No release or publication has been dispatched. This comment supersedes any implication that #2119 plus #644 alone completes the #707 release chain.
@willwashburn Current exact head c35859cff192215c6b2d2d581b3bbbf80f96a1aa is MERGEABLE with all checks green and zero unresolved threads. Prior independent review evidence targets ancestors; stacked replay-resume client PR #2142 is waiting on this base. Please independently review exact c35859c and APPROVE if clean. Approval only—no merge or release requested.
The reason will be displayed to describe this comment to others. Learn more.
Reviewed exact head c35859c against current main 58faeca. The durable strict-invoke/replay server path and its exact-node, logical-request, rematerialized-directory, record-failure, and restart tests are clean; all hosted checks and focused local gates pass.
Blocking finding: this head also changes the public Core Bridge authentication contract in an incompatible way. CallerCredential now rejects schema-1 and legacy schema-2 credentials, and authenticate() calls requireServiceCallerMethods(), so an auth-only client cannot authenticate unless the core advertises the entire identity/inbox/settlement/disconnect lifecycle. The reviewed schema-v2 package successor intentionally preserves readCallerCredential compatibility and makes authenticate require only spawn_callers.challenge/authenticate, with requireServiceCallerMethods as the explicit full-lifecycle admission gate. Please either remove the superseded Core Bridge package changes from #2119 and leave them to the package-only successor, or align this head with that compatibility split and rerun exact-head package tests. Do not land a transient breaking 18.0 surface.
Nonblocking cleanup: split the combined Unreleased changelog entry into concise impact-first bullets and remove the local-ledger implementation backstory, per AGENTS.md.

Independent exact-head verification for d33ab274d79e97cee094a3228eea5ecb19b4c867.
The repair commit removes the superseded Core Bridge auth delta: the four package files are byte-identical to current origin/main, while the durable strict-replay server change remains. The changelog now has one concise user-visible replay bullet.
The Cargo launcher on this host injects SSL_CERT_FILE/SSL_CERT_DIR, which these platform-trust tests intentionally refuse. After compiling this exact head, I invoked its exact test binary under the intended platform-trust environment:
A fresh npm ci attempt could not complete because this host's tmpfs is at 99% inode use (ENOSPC); the package test/build above therefore reused the repository's existing tool binaries against the exact-head sources. Hosted clean CI is the independent install/build gate and still has platform jobs running as of this comment.
No source finding in the repair delta. Snow Lunch has been asked for independent exact-head signoff. No merge or release performed.
Superseded by d33ab27 and current head 2019cf4: the incompatible Core Bridge delta identified by this c358 review was removed, the current PR diff contains only the reviewed four-file Rust/changelog change, and the changelog cleanup was applied. Exact-2019 human review and green CI remain required; this dismissal is not an approval or merge.
Independent delegated source audit at exact 2019cf4f0ed16c12dfdcf37df8666733bea037e4: CLEAN; no blocking source finding. This is evidence for the required human reviewer, not an approval or merge action.
The current head is a two-parent merge of reviewed d33ab274d79e97cee094a3228eea5ecb19b4c867 and current main 1151e99c4bc57a340eff4099d2c20af96a9fdac3. All three Rust source/test blobs are byte-identical to d33; only the whole-file changelog blob also contains unrelated intervening main bullets. The old and current feature deltas both contain the same four files and exactly 505 insertions / 247 deletions.
The host's Cargo launcher injects SSL_CERT_FILE / SSL_CERT_DIR; the core deliberately refuses platform certificate overrides, so the aggregate Cargo invocation is not reproducible here. Running the exact compiled test binary with only those launcher-injected variables removed passes the full focused module:
The audit checked the exact strict-invoke route, stable logical request and key, canonical worker_cwd rematerialization, server-owned proof, lookup-only unsafe-path replay, removal of the local receipt ledger, and unchanged session request/preflight. Relaycast #644 exact cc025be4 matches the request and proof shape.
The stale c358 CHANGES_REQUESTED review has now been dismissed because its Core Bridge blocker was removed at d33; that dismissal is not an approval. Exact-2019 human review and the final hosted macOS job remain required before merge. No release action.
@willwashburn Exact 2019cf4f0ed16c12dfdcf37df8666733bea037e4 is ready for human review: all hosted checks are terminal green (19 success; expected skips only), Greptile and the Flows shard are green, all threads are resolved, the stale c358 review was dismissed after its Core Bridge blocker was removed, and an independent exact-head audit found no source defect. Please approve if clean. Merge only after paired Relaycast #644 lands; no release is requested by this comment.
Current origin/main is 503020b94bc9d1acd065c6f37afc4aaa3fdfd461; PR head remains the previously reviewed 2019cf4.... The overlap is real: current main changes workspace-key-aware HTTP/error handling in control.rs, while this PR changes the durable external-invoke path in the same region.
No branch bytes were changed by this check. Before merge, the branch needs an owner-applied integration of current main that preserves both behaviors, followed by exact-successor tests/review. The existing exact-head signoff cannot be transferred to that successor.
Exact-head merge repair evidence for 8258e208424b45f457bbb152ed014a54cbc72240 (tree 2935c2a370986ea63c417fde7ea94dbe6adfee2b). The branch was advanced normally from 2019cf4f0ed16c12dfdcf37df8666733bea037e4; no force push. Relative to current main, the PR remains the same four-file feature scope. The conflict resolution preserves the strict external replay branch and updates only the session caller target preflight to current-main workspace_http() plus KeyKind-aware error mapping.

The host Cargo process injects SSL_CERT_FILE=/etc/ssl/cert.pem and SSL_CERT_DIR=/etc/ssl/certs into the test executable even if its parent command unsets them. Current main intentionally refuses file-selected trust roots, so invoking through Cargo produces the TLS-guard refusal before the fixture HTTP call. I therefore built with Cargo, then invoked the exact produced test binary with both variables actually absent. This is the literal focused result:

@willwashburn Current exact head 8258e208424b45f457bbb152ed014a54cbc72240 is MERGEABLE with all hosted checks terminal green and zero unresolved threads. The current-main conflict resolution has independent exact-head signoff: external callers retain strict invoke/replay and return before target preflight; session callers use current-main workspace_http(workspace) plus targets(workspace.kind(), ...). Literal evidence is captured in the repair report, independent audit, and terminal gate report. Please independently review and APPROVE exact 8258e208 if clean. No release is requested by this comment; stacked #2142 will be retargeted and revalidated after this base merges.
Independent Snow Lunch exact-head verdict for 8258e208424b45f457bbb152ed014a54cbc72240: SIGNOFF; the merge update is clean. The review confirmed (1) only session callers adopt current-main Workspace/workspace_http target preflight and KeyKind-aware rotation mapping, (2) the #2133 Core Bridge compatibility split is preserved with no auth regression, (3) strict external replay is untouched by conflict resolution, and (4) Cargo-reinjected SSL_CERT_FILE/SSL_CERT_DIR behavior is an environmental guard interaction rather than a source failure. This supplements the literal exact-head repair, independent test, and terminal hosted-gate evidence already linked above. Human approval/ordered merge remains required; no merge or release action was taken.

Outcome
/v1/actions/spawn/strict-invokeroute and require the server-ownedspawn_contract_appliedproof./v1/actions/spawn/replaywhen the requested directory can no longer be safely materialized; the recovery path cannot create, place, or dispatch work.worker_cwdto be rematerialized for the same stable logical request and idempotency key.target_node_id, logical-request, or strict-contract fields.This is the Relay client half of a paired change and requires Relaycast PR #644. Replay-capability strengthening remains stacked separately in #2142 with Relaycast #647.
Current exact head:
8258e208424b45f457bbb152ed014a54cbc72240. It normally merges current main503020b94bc9d1acd065c6f37afc4aaa3fdfd461into the reviewed feature tree. The only substantive conflict was the session-only target preflight: it now uses current-mainworkspace_http(workspace)andtargets(workspace.kind(), ...), while external callers retain strict invoke/replay and return before that preflight. The #2133 Core Bridge compatibility split remains byte-identical to current main.Verification
Literal fresh-install, Core Bridge, TypeScript, formatting, and 39-test Rust control evidence for the exact tree is captured in the exact-head verification comment.

Boundary
This is not a full Flows #707 or live Desktop E2E signoff. It does not merge or release Relaycast, Relay, Core Bridge, or Flows. The complete path still requires the paired server changes, reviewed human merges, official package release, the Flows pin, and live local/remote lifecycle acceptance.
