Why: The first E4 live comparison regressed badly (toolFailures 10->24, toolCalls 63->166) and the instance transcript shows the loop: tagging kernel read_file/grep results put a trailing [src_N] line on the model's own workspace files, the model treated it as external tampering, and re-read/re-edit cycles cascaded into the read-before- write and file-changed guards. Why: The ledger only ever needed SOURCES - searches always, and workspace reads only under inputs/ (the upload material area). Grep cannot distinguish materials from self-produced files, so it stays untagged. Evidence: go test ./... green; new anchor TestEvidenceLedger OnlyTagsMaterialReads pins the inputs/-only rule; the re-run live comparison follows on the Dev side. Impact: evidenceTools loses read_file/grep; isEvidenceRead gates workspace reads to inputs/; everything else (search tags, escalation reminders, prompts) unchanged.
