# Native verification attempt — issue 10056

Candidate b5d438e75bc09811186610d94a58b6636769d0a4; baseline fef851bee09102641061aeb78a3092c2ba2c72ab.

Captured rows: 0/3 (M1, M2, M3 all unverified). No recordings, stills, amplified zero-threshold diffs, or threshold diffs exist. No native device viewport was observed. Requested 390/1440 native viewport coverage is unavailable in this attempt; neither is substituted with responsive web. Light/dark unverified.

Environment: Linux fs-01, isolated checkout /home/ubuntu/.t3/worktrees/t3code/t3-da65ff91 at candidate detached HEAD. EAS whoami authenticated pingdotgg robot; simulator availability returned available:true. No simulator session started. No backend or Metro dev server started. Local export invoked Metro bundler, then was stopped through its retained terminal session.

Temporary changes: simulator profile extending preview, offline harness entry point, mocked thread-selection boundary, production ComposerEditor + useThreadComposerState + production draft persistence and durable outbox manager. Harness does not implement delivery/upload ID rebinding, pending-new-task flow, or server queued editing. It is incomplete and has never been run on native hardware/simulator. No helper-only proof is counted. No implementation changes, commits, pushes, or public forge writes. EAS created issue10056-native update channel/branch as part of build submission; no update was published.

Build attempt: npx --yes eas-cli@latest build --platform ios --profile issue10056-native --non-interactive --no-wait. Source archive 214 MB uploaded. Metadata upload returned HTTP 400. CLI then remained in expo-updates runtimeversion:resolve --platform ios --workflow managed without returning a build ID before teardown. No native artifact available. Local expo export reached Hermes compilation but did not finish. Baseline build was not attempted because candidate never became available. Existing unrelated EAS build failures mentioning GhosttyKit were observed read-only and are not evidence of failure on this candidate.

FRICTION: checkout-dependencies | Expo initially could not resolve expo-asset; vp i completed | install dependencies before EAS commands.
FRICTION: build-runtime-resolution | profile inherited fingerprint runtime resolution; archive uploaded but build ID never returned within budget | use an explicit temporary appVersion runtime policy for the fixture build, then confirm candidate/baseline artifacts before starting a simulator.
FRICTION: fixture-scope | existing showcase requires backend and harness covers only a subset of M1 | complete offline fixture boundary for real new-task/outbox-drain/server-edit production flows before claiming matrix evidence.
FRICTION: host-command-latency | terminal/tool calls experienced unexpectedly large wall-clock delays near deadline | reserve cleanup time and avoid concurrent fingerprint/export jobs.
