Root-caused from the elspeth pre-commit consumer report (2026-07-03): the intermittent first-commit failures were pre-commit 4.6.0's files-modified-during-hook check (run.py:203-235) attributing a concurrent session's tracked-file writes to the slowest whole-tree hook; wardline exited 0 in every observed occurrence (no '- exit code:' line; summary printed — unreachable on any exit-2 path). Reproduced in a sandbox both ways (fail + clean retry). The CLI now ends an armed pass with gate: PASSED (--fail-on [, --fail-on-unanalyzed]) — gate: evaluated on stderr — same knob-attribution grammar as the FAILED branch; decision layer unchanged (GateDecision already carried verdict=PASSED + reason + evaluated). RCA + audit evidence (no silent exit-2 paths; publishes cannot escalate; torn reads are gate-eligible per-file findings) in docs/handoffs/2026-07-03-elspeth-precommit-intermittent-rca.md.

The scan now stat-snapshots the discovered inventory at discovery (st_mtime_ns, st_size) and re-checks after analysis; any file written, truncated, or deleted in the window becomes a WLN-ENGINE-TREE-CHANGED-DURING-SCAN FACT (severity NONE, never gates, not an under-scan) naming the files and the pre-commit consequence, echoed by the CLI as a warning and carried in the MCP result and artifact via the NESTED-SCAN-ROOT FACT-carrier pattern. Detection sees only the discovered inventory — a concurrent write to a non-source tracked file is invisible here, hence the message's "may". 3 engine tests (mutation via the progress_callback seam, deletion, quiescent negative) + 1 CLI echo test; glossary line-anchors re-synced after the run.py insertions.

(The non-UTF-8 case was already handled by this branch's _read_store_text_no_follow decode guard — test carried anyway as a pin.) 3 regression tests ported. After this, local main's unique content is fully subsumed and main can be realigned to origin/main.
