Fixit: Home, Car or Pet Problem to Safety-Gated Fix Plan

# Title: Fixit: Home, Car or Pet Problem to Safety-Gated Fix Plan
#
# Public workflow: take a description of something broken at home, in the car, or
# with a pet; decide first whether it is a stop-and-call situation; and only if
# it is not, route to the matching specialist for a ranked diagnosis, a DIY-vs-pro
# call, and a fix plan that an independent auditor checks for safety before it is
# delivered. Graph routing: a STOP verdict skips the plan entirely.
#
# Shape:
# classify (CATEGORY + SAFETY, fail-safe default = STOP) ->
#   SAFETY: STOP  -> stop (immediate safe actions + who to call) -> end
#   HOME | VEHICLE | PET -> plan <-> audit loop (specialist vs ai:evals) ->
# deliver (final plan, with a banner if the audit never cleared).
#
# Safety contract: the classifier errs toward STOP, and anything it cannot parse
# routes to STOP. The auditor fails any plan that offers gas, in-panel electrical,
# structural, brake-hydraulic, fuel-system, high-voltage, or pet-dosing work as
# DIY, omits escalation triggers, or states an unsourced price or part number as
# fact. Pet output is triage and information, never a diagnosis or a dose.
#
# Roles: `home:diy`, `vehicle:mechanic`, `vet:general` author; `ai:evals` is the
# independent auditor; `assistant:general` handles the STOP message and delivery.
#
# Input shape: describe what is wrong, where, since when, and any model or
# species details. Example:
#   Kitchen faucet drips every few seconds even when fully closed, single-handle
#   Moen, house built in 2004, water pressure normal.
#
# Note: `retries = 2` guards transient provider/network errors on steps that
# search the web for prices and local services. Public roles only.

CATEGORY is exactly one of HOME (house, apartment, appliance, plumbing, wiring),
VEHICLE (car, motorbike, EV), or PET (dog, cat, or other companion animal).

SAFETY is STOP when ANY of these is present or plausibly present; err toward STOP:
- HOME: gas smell or suspected gas leak; carbon monoxide alarm or symptoms
  (headache, nausea, drowsiness with a fuel appliance); exposed, sparking,
  smoking, or hot electrical parts or a burning smell from outlets or the panel;
  water flooding near electrical outlets or the panel; structural cracks wider
  than 6 mm, sagging floors or ceilings, a leaning wall; fire or smoke.
- VEHICLE: brake pedal sinking or soft, brake warning light with a pedal change,
  grinding brakes; steering loss or sudden steering change; fuel smell or leak;
  overheating, steam, or red temperature or oil-pressure warning while driving;
  smoke or burning smell; flashing check-engine light with shaking; any damage
  to a hybrid or EV high-voltage system or orange cabling.
- PET: swallowed or suspected toxin (chocolate, xylitol, grapes or raisins, lilies
  with a cat, antifreeze, rodenticide, human medication); trouble breathing or
  blue or grey gums; seizure; unproductive retching with a swollen abdomen;
  a male cat straining to urinate with nothing coming out; heatstroke signs;
  collapse; trauma such as a car strike or fall; sudden eye injury.
Otherwise SAFETY is PROCEED.

Start with one line: `STOP — do not attempt to fix this yourself.` Then:
1. Do now — 3–5 numbered, concrete, safe actions for this signal (leave the
   building and do not touch switches for gas; open windows and get outside for
   carbon monoxide; shut off water at the main only if reachable without
   touching wet electrical; pull over safely and switch off the engine for a
   vehicle; keep the animal calm and warm, bring the packaging for a toxin).
   For a pet give no medication, dose, or home antidote, and do not induce
   vomiting.
2. Call — who to ring first, by category: emergency services or the gas, power,
   or water utility emergency line (HOME); roadside assistance or emergency
   services (VEHICLE); the nearest emergency vet or a national animal poison
   line, calling ahead while travelling (PET). Do not invent phone numbers; say
   "your local emergency number" or "your utility's emergency line".
3. Do not — the one or two tempting mistakes for this signal.
4. Tell the professional — a two-line summary of what you saw, heard, or smelled
   and when it started.

Output only this message.
