🟥 Issue titles enable command injection
A crafted issue title reaches f.run through JSON.stringify, which does not escape shell syntax. Command substitutions execute under the hosted deployment identity.

Fixed in 725d882: the recorded flow single-quotes the issue text via shellWord (your suggested form); the README notes that the smoke run itself predated the fix.

- Around line 1-10: Update the smoke flow around the f.run call to shell-quote
the constructed issue message before passing it to /bin/sh, preventing titles or
labels containing shell metacharacters from being interpreted. Add a local
shellWord helper or equivalent escaping logic, use it for the message argument
to printf, and preserve the existing output and f.done("success") behavior.

Review on #444: the smoke listener's flow interpolated the issue title via JSON.stringify into /bin/sh. The recorded flow now single-quotes it and the README says the run itself predated the fix. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Evidence only — no code. Records every production proof for #440, the v2.0.16 release, the runtime artifact hash cross-check, the pin move (with the previous values for rollback), and two cloud-side observations.

Overview
Adds an evidence-only bundle under
evidence/440-hosted-cli/documenting production validation of the hosted CLI and the Cloud runtime pin move to v2.0.16 (fe8d7606).The new
README.mdindexes proof runs (cloudflows runwith sync, deploy/undeploy, issue-triggered listener, npmrelayflows@2.0.16sync round trip, and./run.shon the pinned runtime) with run IDs and outcomes. It also records the verified artifact sha256, pre-pin rollback values inpin-before.txt, S3 publish vs failed R2 publication, and two unfixed Cloud API observations (completionReason: null, no step stdout).Supporting artifacts include YAML smoke flows (
proof.flow.yaml,pin-proof.flow.yaml), CLI transcript files, andissue-echo.flow.tsshowing the post–#444 shell-quoting fix for issue title text (contrasted with the pre-fix listener run).Reviewed by Cursor Bugbot for commit 725d882. Bugbot is set up for automated code reviews on this repo. Configure here.
Summary by cubic
Adds production evidence for #440: the hosted CLI works against Cloud, the v2.0.16 runtime artifact is verified, and Cloud’s runtime pin has moved to v2.0.16. This is an evidence-only change, so no product code or runtime behavior is modified.
Evidence recorded
relayflows@2.0.16syncs and runs successfully from npm.completionReason, and step stdout is not exposed via the runs API.Written for commit 725d882. Summary will update on new commits.
