Appends the R3 section to agents/steelbeak/work/queue-227/BUILD.md: the
R2 red on dummy links, the fixes, how the TMPDIR limit is derived, the
namespace containment and control table, runs, signal probes, the tip
check on 5df0e9d6f and follow-ups. One line each in BUILD-LOG.md and
docs/SESSIONS.md. Earlier entries are unchanged.
Appends the "R2" section to agents/steelbeak/work/queue-227/BUILD.md: findings and fixes,
no step failures past launchFixture, the environment and signal controls, the mutant table
(m6 on requireCitation survived and is a follow-up), run times and the tip check. One line
each in BUILD-LOG.md and docs/SESSIONS.md. Earlier sections are unchanged.
Unclaimed files left in the canonical checkout. Inventory: canonical-cleanup-inventory.md (commit-as-evidence groups). detect-secrets scan clean on 2026-11-02: hits are sha256 pins, git object ids, test sentinels already in tracked tests and unit-file lines.
The row 173 test called setup(false), which starts the page with Show machine sessions off, so the sessions table it waits for never renders. Its sibling uses setup(true). Change the one argument; app.js is unchanged. The same test fails on the r2 tip 6d15eb5fc2, so base drift was not the cause.
(cherry picked from commit 996c79524f)
Commits the row 227 evidence under agents/steelbeak/work/queue-227/: the remaining gate/ files, runs/ (first, corrected1, priorityprobe), target-packet, target-packet-r2, target-packet-r3, target-packet-r4, static/, and the two top-level manifests. Also commits BUILD.md and the append-only BUILD-LOG.md and docs/SESSIONS.md entries. The R4 packet hashes are PACKET.sha256 4eb60915b2144137df9b5a42afd0c5b266718d71de051fb8be53a27430a2cad4 and CURRENT-SOURCE.sha256 0cfd47c2073bc18a3ba7bff1ce6fdf39fe33a64b7fca209be71517b9feb89020, both checked against the files. The overlay bytes are committed in 4ac6f13bc. This commit adds receipts and packets only and records no scripts/test-case2.sh run on the R4 overlay.
#156 changes src/run-agent.sh and src/load-contracts.sh, which are baked into
the worker image. Its run-agent.sh refuses to start unless the launcher sets
MOSAIC_SYSTEM_PROMPT_FILE, and no launcher before #156 does. Rebuilding the
shared 0.0.12 tag would break the live pinned copy and rollback targets, so the
new image gets its own tag. No code change.
