Moos ivp eval mission builder

MOOS-IvP Eval Mission Builder

Overview

Use this skill for one self-evaluating mission folder: a normal MOOS-IvP mission with an added single-run grading contract. The mission should still be readable and runnable by a person, but it must also run headlessly, decide pass/fail inside the mission, write results.txt, and finish through the shared xlaunch.sh / uMayFinish path.

For ordinary mission layout, use moos-ivp-mission-builder first. For multi-case matrices, patch sweeps, parallel runs, or expected-vs-actual aggregation, use moos-ivp-harness-builder. For post-run .alog evidence, use moos-alog-analysis.

Core Rules

• Start from an ordinary mission that already launches cleanly. Prefer the moos-ivp-mission-builder baselines or an existing nearby mission family.
• Add only the evaluation plumbing needed for one scenario: optional pAutoPoke, optional uTimerScript, pMissionEval, results.txt, and a thin zlaunch.sh.
• Keep launch.sh human-facing. It may accept --xlaunched, --nogui, and port overrides, but it should not contain case loops or result aggregation.
• Keep zlaunch.sh thin: parse automation arguments, truncate results.txt, call shared xlaunch.sh, validate that results.txt contains grade=, then apply project-local scoped cleanup.
• Let xlaunch.sh --max_time=<secs> own uMayFinish and the timed wait/stop contract. Do not duplicate that lifecycle in mission-local wrappers.
• Do not synthesize grade= or write the final result row from zlaunch.sh, launch.sh, or target-file parsing. pMissionEval must own the verdict and write results.txt; wrappers may only truncate, launch, wait, validate presence of grade=, and clean up.
• For cleanup backstops, copy assets/moos_scoped_teardown.sh into the target project as <project-root>/scripts/moos_scoped_teardown.sh if it does not already exist. Reuse an existing project-root helper unless it is clearly stale or incompatible.
• Prefer pAutoPoke to seed deploy and evaluation variables in moving missions. Unit-style evals may use uTimerScript or the app under test for readiness when there is no vehicle/deploy lifecycle. Do not put pass/fail logic in pAutoPoke.
• Use pMissionEval as the primary verdict owner. Prefer mission-level booleans or simple scalar checks over harness-side parsing of raw MOOS traffic.
• Prefer event-driven pMissionEval leads: evaluate when the mission-owned completion event occurs. Use uMayFinish through xlaunch.sh --max_time as the outer infrastructure ceiling. Use a time-driven evaluation-window lead only when non-completion is an expected mission outcome that should produce mission-owned grade=fail.
• Multiple lead_condition lines in the same aspect are allowed, but they are ANDed: all must be true before pass/fail conditions are evaluated. A lead_condition after pass/fail conditions starts the next ordered aspect. A single lead_condition may use textual or when each operand is parenthesized, for example (EVENT_A = true) or (EVENT_B = true). Do not use ||; it is not a supported LogicCondition operator.
• Treat BHV_ERROR_SEEN=false as a normal safety/integrity pass condition. Treat BHV_WARNING as advisory development evidence by default: inspect and investigate it with appcasts or .alog tools, but do not add a sticky BHV_WARNING_SEEN mailflag, result column, or pass condition unless the scenario is explicitly warning-intolerant and the warning signal is known to be stable rather than transient/retracted.
• Keep results.txt scalar and parseable. The only hard schema requirement is grade=<pass|fail>; fields such as form=, eval=, timeout=, domain facts, and mhash= are recommended evidence, not a mandatory metric set.
• mission_mod is optional mission-owned provenance. Use it only when one mission folder intentionally supports multiple named standalone modes. Omit it from single-scenario eval missions, and do not use it to represent harness cases.
• If a vehicle-local variable is graded shoreside, bridge it explicitly through the vehicle broker and shoreside broker.
• For GUI-capable eval missions, keep normal operator buttons available. Do not force appcast/realmcast viewer modes unless the evaluation scenario needs it.
• Do not add --case, --jobs, temp mission copies, per-case port blocks, or expected-vs-actual aggregation here. Those belong to the harness builder.

Workflow

1. Confirm the base mission launches and generates targets.
2. Identify the smallest mission-owned pass/fail signal.
   • unit-style app variable
   • behavior end flag
   • arrival/collision/encounter outcome
   • load/process/host info signal
3. Add evaluation state to the relevant .bhv or app config.
   • When adapting an ordinary waypoint mission, make the graded behavior finite, such as repeat = 0, or add an explicit completion flag. A repeating operator survey is usually not a valid eval completion signal.
4. Bridge graded vehicle-local variables to shoreside when needed.
5. Add pAutoPoke or an equivalent explicit initializer for deploy and evaluation variables.
6. Add pMissionEval with simple lead condition(s), clear pass conditions, result_flag = MISSION_EVALUATED = true, and report_file = results.txt.
7. Add or update zlaunch.sh to set a mission-appropriate MAX_TIME default, accept --max_time=<secs> as an override, and forward the final value to xlaunch.sh --max_time=<secs>.
8. Add or update README.md with scenario, grading signal, and run commands.
9. Validate target generation, then run the headless cycle and inspect results.txt.

Reference Use

• Read references/eval-mission-style.md for boundaries and file layout.
• Read references/evaluator-apps.md before wiring pAutoPoke or pMissionEval.
• Read references/scenario-and-grading.md before grading obstacles, contacts, moving/integration outcomes, or structured payloads.
• Read references/zlaunch-xlaunch.md before editing automation wrappers.
• Read references/validation.md before reporting an eval mission as done.
• Copy assets/eval-single-vehicle/ when a concrete minimal moving example is useful.
• Copy assets/moos_scoped_teardown.sh into the target project as <project-root>/scripts/moos_scoped_teardown.sh when the project does not already have an equivalent root-scoped helper.
• Run scripts/static_check_eval_mission.sh <mission-dir> for a quick structural check.
• Run scripts/live_check_eval_mission.sh <mission-dir> --port_base=<free-base> for bundled-example or high-trust validation when MOOS-IvP runtime tools are available.
• Treat live-check teardown failure as a test failure, show the teardown error, and preserve the temporary workdir for diagnosis.

Validation Checklist

• ./launch.sh --just_make --nogui <warp> succeeds.
• Generated targets contain pMissionEval, explicit initialization (pAutoPoke, uTimerScript, or an app-owned producer), and any evaluator apps needed for reported columns such as pMissionHash.
• If pMissionHash is used for mhash= evidence, keep it headless-only by default; GUI targets should not launch both pMissionHash and pMarineViewer unless the overlapping pMarineViewer hash feature is deliberately disabled.
• Generated targets include bridged graded variables if the verdict depends on vehicle-local posts.
• ./zlaunch.sh --just_make <warp> succeeds when xlaunch.sh is on PATH.
• Headless ./zlaunch.sh --max_time=<secs> <warp> exits cleanly.
• results.txt contains one parseable result line with grade=.
• Runtime warnings are investigated during validation; only stable, scenario-relevant warning metrics are surfaced in results.txt.
• High-trust checks use scripts/live_check_eval_mission.sh or equivalent to verify result rows, surface warning evidence, and detect leftover listeners on scoped ports.
• No mission wrapper uses global ktm, pkill, or unrelated cleanup.
• Eval wrappers use <project-root>/scripts/moos_scoped_teardown.sh as a scoped backstop after xlaunch.sh; they do not use global ktm, pkill, or broad process discovery.
• GUI runs retain normal operator controls unless the user requested a headless-only mission.
