write/edit failures with FS_STALE_VERSION or FS_NOT_OBSERVED now reach the model with the correct recovery instruction appended (re-read / read, then retry) while preserving the structured code and chaining the cause. The edit-intent waterfall sits inside the same try, so the policy's FS_NOT_OBSERVED refusal is remediated too. Re-recorded the fs-policy-reject keyless snapshot and the bilingual README pairs.
