Settle folded steering submissions by delivery identity

[e0-gh-vercel-connect]

Rapid steering follow-ups can be accepted together and represented by one canonical message.received event. Before this fix, the client store retired only one optimistic submission per receipt, leaving another projected and allowing the active turn to end in error.

Hypothesis

If each optimistic submission keeps the server-issued delivery identity, then a folded receipt can retire every accepted submission it owns while projecting the canonical event once. The active turn can then count accepted and received follow-ups by identity instead of by event count.

Changes

• Expose the accepted delivery identity on MessageResponse without changing legacy stream filtering
• Bind initial and follow-up optimistic submissions to their accepted delivery identities
• Settle all matching submissions from message.received.meta.deliveryIds and retain a metadata-free fallback for legacy receipts
• Track folded follow-up delivery identities and add a patch changeset

Validation

• EveAgentStore suite: 25/25 passed
• Folded-steering regression: 1/1 passed
• TypeScript, formatting, diff checks, and the 700-line structural test passed
• The red regression remains preserved as the first commit on this draft

Package Drill-Down

Package Details

• Package: eve@0.54.3
• Package directory: packages/eve
• Tarball: 8.78 MB (eve-0.54.3.tgz)
• Unpacked payload: 33.07 MB across 3967 published files
• Installed footprint: 78.61 MB across 7888 installed files
• Installed root package: 31.64 MB
• Installed dependencies: 46.98 MB
• Installed package instances: 33
• Distinct installed package names: 32
• Installed dependency edges: 51
• Installed optional peer edges: 8
• Runtime dependencies: 2
• Peer dependencies: 6 (5 optional)

Installed footprint is measured from an isolated temporary npm install of the packed tarball.
Graph metrics read only package.json files in package directories directly beneath a node_modules boundary, including nested boundaries. Each directory is one package instance; distinct names come from those manifests. Dependency edges count each unique name in dependencies or optionalDependencies per instance; optional peer edges count peerDependencies marked optional.

Build Timing: e2e/fixtures/agent-tools-sandbox

This is an informational timing measurement inside eve build, from preflight through publication. Output-size measurement and profile writing are excluded.

Build mode: deployable Vercel build with sandbox template prewarm included.

• Build pipeline: 6.15 s -> 6.01 s (-143.2 ms) vs main (7fa514b).
• Timing is informational: shared GitHub runners are too variable for a hard timing budget.

[e0-gh-vercel-connect]

Workflow run 34699971102 failed only in unrelated e2e-local model-evaluation jobs:

• agent-prompt-cache / anthropic-opus: a model call failed, then cache-read assertions and a subagent-call assertion failed.
• agent-task-reporting / openai-sol: one expected natural-language tool result differed.

The PR changes only EveAgentStore unit-test coverage, and neither failure exercises that test. This was attempt 1, so I retried the two failed jobs once. The rerun is currently queued.

[e0-gh-vercel-connect]

Workflow run 34699971155 failed on its first attempt.

I could not retrieve its job details or logs because GitHub’s API is rejecting the available credential with 401 Bad credentials; the unauthenticated public API fallback also returned 401. With no evidence of the failing job or cause, I did not rerun it blindly.
