The progress file /trekexecute's prose described did not pass the command's own validator: run status in-progress and no partial, no plan_version (required), step status running and passed. Measured on the 4 real progress files: 3 used passed, 2 failed on plan_version. The prose now speaks the validator's vocabulary, site by site: schema (plan_version = the value Phase 2 parsed; run status in_progress|completed|failed|stopped|partial), fresh-mode warning, both resume rules, step start in_progress, step finish completed, the escalation staging rule, the Phase 7.5 commit count (status=completed - left alone, every successful run would read as drift and be overridden to partial) and the final write (adds partial; a sandbox-blocked run writes stopped, report result blocked). Untouched on purpose: plan_verification.status, session-state / NEXT-SESSION-PROMPT status, stats and report result, the tolerant session-orders reader list, Phase 2.6's running state.
Valgt: tolerate a legacy passed on resume (one sentence after each resume rule) because Voyage is a public plugin and an in-flight run written under the old prose would otherwise re-execute finished steps. The validator gets no alias. Valgt: fresh mode also warns for stopped and partial - both are resumable, so they now get the --resume hint instead of a silent overwrite (intended behaviour change).
Red: 3 of 5 new tests fail on the pre-fix text - SC4 (documented progress file validates 0/0 per run status), SC5 (offenders at trekexecute.md 1011, 1055, 1062, 1164, 1169, 1326, 1352, 1489), the legacy-sentence count. Regression guard and known-positive control green on arrival.
Verify 125/125 (trekexecute-progress-schema, trekexecute, session-orders, criteria-runner, progress-validator). Suite 1388 (1386/0/2).
Voyage order 20261005T104513Z-1250514346, plan step 4/5.
