#!/usr/bin/env bash
# gate-task.sh — the Snorkel Terminus 3 gate for ONE task dir (terminus3-fbplus-cad).
# Hand-maintained apparatus (NOT generated — no generator touches this file).
# Backs GATE_CMD in project.env; gate.sh delegates here. Usage: gate-task.sh <task-dir>
# Phases: A = structural (always, fast). B = docker (skipped when GATE_FAST=1 — mid-work
# checkpoints only; a LANDING gate always runs both phases).
#
# Schema authority (platform static-check update supplied 2026-08-05): task.toml
# uses the TBench 3.0 post-update sectioned schema. A bare name and artifacts remain
# top-level. Descriptive, taxonomy, and scoring fields live under [metadata]:
# author_name, author_email, difficulty_explanation, solution_explanation,
# verification_explanation, relevant_experience, category, subcategory, tags,
# expert_time_estimate_hours, difficulty, and languages. [agent], [verifier], and
# [environment] retain their established fields; network_mode remains under
# [environment]. There is no [task] section or schema_version.
# Enforces guardrails.yaml G-TASKTOML/G-SCHEMA-RECONCILED (TBench 3.0 sectioned
# schema), G-CATEGORY, G-REWARD-CONTRACT, G-NO-CANARY, G-NO-NETWORK, G-INSTRUCTION-STYLE,
# G-VERIFIER-ISOLATION (image proof), G-COMPOSITION-LOCK, G-NO-META-FLOW, plus the
# deliverables list (TASK-STANDARDS.md §5, 5-item lock — README.md FORBIDDEN at unit
# root: added by Snorkel at packaging, same channel as rubrics.txt; §8 row 23).
# Composition rule (5-item lock): a delivered task dir contains ONLY task.toml,
# instruction.md, environment/, solution/, tests/ — the task is the RESULT of
# the flow, never a record of it. jobs/ (stb harbor runner output) is tolerated during
# mid-work checkpoints but MUST be gone at landing: never packaged, never shipped.
# The oracle-roundtrip runner is apparatus and lives OUTSIDE the artifact at
# _build/oracles/<slug>/gate-oracle.sh.

=== OUT-OF-SCOPE block ===
OUT-OF-SCOPE: |
  Touching ANY of these is a stop condition:
    - every other task dir under tasks/ in EVERY lifecycle stage
      (tasks/accepted/, tasks/reviewing/, tasks/working/) — including
      tasks/accepted/ball-valve-parametric and tasks/reviewing/eir-dc-motor
      (read them as templates, never write to them)
    - every other workdir under _build/work/ and every other oracle dir
      under _build/oracles/ — this is a solo unit, never a fan-out; nothing
      here implies or authorizes a sibling batch
    - extracted/, extracted2/, stlFiles.zip, "Peer Coaches Frontier Bench
      Spec Doc  .md", _build/inventory/manifest.yaml, think-like-fable/ —
      P-IV no-touch, read-only if you ever need to (you should not need to;
      this unit has no sourced input beyond the supplied output_shaft.stl
      fixture the spec itself hands you)
    - the zip files other than your own deliverable
      (tasks/**/*.zip except tasks/working/planetary-gearset.zip)
    - company/ (queues, NOTES.md, staffing.yaml, CONTRACTS.md) — conductor
      and CEO files, never yours to edit
    - canon files (CLAUDE.md / AGENTS.md, kernel/, CONSTITUTION.md)
    - this packet file itself (.packet.md) — leave it exactly as delivered
    - any platform submission / upload act (stb submit and similarly named
      commands) — Founder-only, per CONTRACTS §5; nothing in this packet
      authorizes it
  No agentic-flow vocabulary in ANY unit file (no "packet", "conductor",
  "dispatch", "oracle", "worker", "gate" — say "reference solution" in unit
  prose if needed). No marker strings (G-NO-C*). No network at run/verify
  time — bake everything into images (docker build-time pulls are fine).
