Summary

The claude-code, gemini and opencode agents' changelog captures pass --ignore-failed-read to GNU tar. A file the agent can't read no longer drops the whole increment. It's skipped, and the rest of the tool call's writes are captured and uploaded.

Why

claude-code and gemini capture /usr/local and /etc by default, beside the workspace and the CLI's state. Their images run as the non-root user agent. Where the agent runs as that user, as in a VM sandbox's container, tar can't read root-only files such as /etc/ssl/private and exits 2:

[changelog] tar failed seq=1 rc=2: tar: /etc/ssl/private: Cannot open: Permission denied

The post-tool hook treats exit 2 as a failed capture, so it uploaded nothing. An apply-changelog then had no increments to replay. The validator's round trip reported save: true, apply: true, roundtrip: false, and the marker file never reached the apply agent. Where the agent runs as root, as on a container sandbox, every file is readable, so the round trip passed there. That's why it failed on VMs only.

A file the agent can't read is one it couldn't have written, so skipping it loses none of the agent's changes. With the flag, tar exits 0 when the only problem is an unreadable file. A file that changed while it was read still exits 1, which the hook already accepts as a warning.

opencode captures only its workspace by default, so it didn't hit this. Its capture gets the same flag, because a caller may name other roots.

Testing

• Unit:

  • claude-code's and gemini's new test: a root holding a directory the test user can't read. The hook still exits 0, logs captured seq=0, and uploads the new file. It's skipped as root, who reads everything, and without GNU tar, like the other changelog tests.
  • opencode's two capture tests located --listed-incremental= by its position in the tar command line. They now find it by prefix, and one of them checks that --ignore-failed-read is passed.
  • The three agents' changelog and object-transfer suites pass with GNU tar 1.35: 192 passed, 4 skipped. The two opencode tests failed until their fakes were updated.

• End to end, in a deployment's dev stage on VM sandboxes, with the validator's own round trip (capture agent, marker write, apply-changelog onto a fresh agent, marker check):

  agent, released image	capture hook	increments	roundtrip
  gemini 0.9.1366	as released	0 (tar failed … /etc/ssl/private)	false
  gemini 0.9.1366	--ignore-failed-read added in the running container	2	true; the marker and its token are in the apply agent's /app
  claude-code 0.9.1366	as released	0 (same error)	false
  claude-code 0.9.1366	--ignore-failed-read added	2	true

### Issue 1
tst/unit/agents/gemini/test_object_transfer.py:401-402
The new Gemini test writes `marker.txt` but only checks that an archive was uploaded. An archive containing metadata alone would pass, even if readable writes were lost. Check that the uploaded archive contains `marker.txt`, as the Claude Code test does.

Summary

Adds --ignore-failed-read to baseline and capture commands for Claude Code, Gemini, and OpenCode.

• Changelog captures skip unreadable files and keep archiving readable changes.

earakely-scale explicitly identifies skipping unreadable files as intentional so other writes can still be captured.
