Orchestra sets CLAUDE_CONFIG_DIR=/home/ubuntu/Orchestra/data/claude_creds/max_outlook/
in the subprocess environment (see orchestra/auth.py lines 918–926). Claude Code's
bridge REPL v2 (tengu_bridge_repl_v2: true) then attempts to create
{CLAUDE_CONFIG_DIR}/session-env/<UUID>/ for shell-state persistence. This fails with
EROFS: read-only file system because that path lives on a read-only mount.
Fix required (by human operator or supervisor):
mkdir -p /home/ubuntu/Orchestra/data/claude_creds/max_outlook/session-envconfig_dir for the max_outlook account in Orchestra's DB to a/tmp/claude-max-outlook), OR

Problem identified: The backfill script's _infer_from_metadata only looked for paper_id in metadata, but paper_figure artifacts store the PMID under the key pmid (not paper_id). Additionally, figure artifacts (15K+ isolated) were not being linked despite having metadata.analysis_id that maps to existing analysis artifacts.
Fixes applied to scripts/backfill_isolated_artifact_links.py:
pmid handling in _infer_from_metadata: when pmid is a numeric string (not a UUID), link paper_figure to paper-{pmid} artifact with cites link type (strength 0.9).figure artifact type handling in _infer_from_metadata: link figure artifacts to analysis via metadata.analysis_id with derives_from link type (strength 0.95).--scan-limit from 500 to 5000 because top-scored isolated artifacts are mostly unlinkable paper_figures with UUID PMIDs; need to scan deeper to find linkable figures and notebooks.Execution results:
