Harden FirstMate delegation producer for V1.2 - #9
Conversation
📝 WalkthroughWalkthroughThe change adds a FirstMate delegation producer and CLI. It validates and signs estate envelopes, restricts sidecar paths, persists artifacts atomically, supports the ChangesFirstMate delegation flow
Priority: ⬇️ Low Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟡 Moderate · up to The delegation producer can reject valid sidecar locations on macOS and may access signing keys before rejecting an unauthorized destination; its traversal coverage can also fail on Windows. These path and operation-order issues should be corrected before merge. Sequence Diagram(s)sequenceDiagram

There was a problem hiding this comment.
The default production path invokes createSignedMessage() directly, bypassing the repository-mandated sign-outbox-message.js wrapper and its outbound-message enforcement. This means the new CLI does not follow the required signing path even though it emits an Archivist envelope; refactor the approved wrapper into an importable API or invoke it rather than calling the low-level signer.

There was a problem hiding this comment.
This envelope declares schema version 1.3 while using to: "control-plane", which the checked-in schema documents as introduced only in v1.6; a consumer selecting validation semantics by the declared version can therefore reject every produced delegation. The repository messaging protocol also requires at least v1.4, so emit the current compatible version rather than 1.3.

There was a problem hiding this comment.
Every generated delegation body starts directly with the serialized {kind, delegation} object and contains no OUTPUT_PROVENANCE header or equivalent metadata. Because this artifact is user-facing lane output and bypasses send-message.js, nothing later injects the mandatory provenance, so emitted delegations violate the output contract and cannot be traced to a session.

This commit adds the dispatch CLI, producer utility, and focused test without adding them to SCRIPT_INDEX.md. The repository explicitly requires every new Ubuntu script to be indexed with ownership and last-use information, so these operational entry points are undiscoverable to agents and subject to being treated as nonexistent or stale.

There was a problem hiding this comment.
When the authorized sidecar directory does not yet exist but one of its ancestors is a symlink, mkdirSync(..., {recursive:true}) creates the directory through that symlink before realpathSync detects the mismatch and throws. Thus a rejected request still mutates a location outside the authorized tree; validate the nearest existing ancestor or create/open path components without following symlinks before performing any filesystem write.

There was a problem hiding this comment.
For two dispatches with the same request_id, the deterministic task ID resolves to the same final path while timestamps and signatures differ. On POSIX, renameSync silently replaces the first artifact, so one idempotency key can identify two different signed contents and a polling consumer can observe either version; on Windows the same retry instead fails because rename does not replace an existing file. Detect an existing task and return it or reject the collision rather than overwriting it.

There was a problem hiding this comment.
If writeFileSync fails after openSync succeeds—for example because the filesystem fills—the finally block only closes the descriptor and the cleanup around renameSync is never reached. This leaves a partial .tmp-* artifact in the sidecar despite the stated no-partial-write contract; wrap the complete write/fsync/rename sequence with cleanup that unlinks the temporary path on every failure.

There was a problem hiding this comment.
An unauthorized sidecarDir is resolved only after signing, so rejection depends on signing keys and transitive signer dependencies being available. In an unprovisioned or damaged signing environment, the CLI throws a module/key error instead of the expected SIDECAR_ROOT_NOT_AUTHORIZED refusal—this also makes the newly added CLI refusal test fail—and in a healthy environment it unnecessarily signs data that can never be persisted. Resolve and authorize the destination before calling signOnce.

Build the traversal test path with path.sep. The CI workflow runs on windows-latest. On Windows, the / separators in evil are normalized before resolveSidecarRoot checks path.sep, so the test receives SIDECAR_ROOT_NOT_AUTHORIZED instead of SIDECAR_PATH_ESCAPE. Use platform-specific separators for the traversal inputs.

Compare canonical paths on both sides, otherwise a legitimate root under a symlinked ancestor is refused.
real !== normalized fails when any ancestor of an authorized root is a symlink, even when the root does not escape. On macOS, os.tmpdir() returns /var/folders/..., and /var is a symlink to /private/var. The fixture roots in scripts/test-firstmate-delegation-producer.js are created under os.tmpdir(), so every produce() call throws SIDECAR_SYMLINK_ESCAPE on that platform.
Canonicalize the authorized roots and compare realpath against realpath. The escape check stays intact, because a root that resolves outside every authorized root still fails the comparison.
