v1.4.0

Changed

• findings.md lifecycle expanded — File Lifecycle Matrix updated: REFLECT gains R (read to check contradictions), RE-PLAN gains R+W (can now correct wrong findings)
• EXPLORE subagent coordination — main agent owns findings.md index; subagents write only to findings/. Correction format: [CORRECTED iter-N]
• PLAN gate check enforced — "read first" → explicit gate: "If not read → read now. No exceptions."
• EXECUTE surprise discovery rule — unexpected findings noted in state.md, step finishes or reverts, then transitions to REFLECT. No silent findings updates during EXECUTE.
• REFLECT reads findings — explicitly reads findings.md + findings/* to detect contradictions from EXECUTE. EXPLORE transition now triggers on contradicted findings.
• RE-PLAN can correct findings — if earlier findings proved wrong, update with [CORRECTED iter-N] + reason. Append-only (don't delete original text).
• file-formats.md updated — findings.md template adds ## Corrections section and documents index ownership
