SOURCE OF TRUTH

What This Maps

Source: huint_supabase/migrations/20260820100000_baseline_prod_v2.sql (single migration, current baseline, no forward migrations on top of it), cross-checked against Huint_mcp/src/createTask.ts and the RPC bodies it calls. Columns that exist in the DB but nothing writes today — photo_notes, additional_details, priority, is_test, photo_guidance_url, webhook_*, metadata, location_display_snapshot, submissions.ip_lat/ip_lng — are cut. Each was checked against every read/write across the whole migration.

MCP input? — yes an agent sets it via create_photo_task/quote_task · derived = set automatically from another input · computed = system-owned, never agent input.

01 / TASKS

The Core Object

IDENTITY & OWNERSHIP

uuid

computed

operator_id

uuid

derived

from the authenticated bearer

api_key_id

uuid

derived

which API key authenticated the create, if API-key auth

agent_id

text

derived

from X-Huint-Agent-Id header or key/JWT-derived default

agent_context

jsonb

derived

always {“agent_id”: “<agent_id>“}

agent_task_id

text

YES

agent’s own idempotency key, 1–200 chars, required

CONTENT / INSTRUCTIONS

title

text, ≤80 chars

DB allows ≤500 chars; the MCP tool itself caps input at 120 chars today (tighter, UI-driven)

media_type

text

computed

1 live value: photo

required_media

integer, 1–10, default 1

YES

legacy aliases required_photos/photo_count are silently mapped onto this

task_type

text

computed

1 live value: picture_required (the default) — drives the map-pin icon / capture flow

LOCATION & REACH

location_mode

text

YES

via location.mode — 4 live values: anywhere, fixed_location, city, zip_code

location

geography(Point,4326)

derived

$1.00 floor

platform_fee_cents

integer

computed

round(bounty_cents * 0.10)

prize_cents

operator-managed display-only grand prize; never escrowed, excluded from the hold, never shown to a tasker as expected earnings

SLOTS / CONTEST

max_taskers

05 / ENTRY_QUESTIONS · 06 / LOCATION

The Sub-Shapes

ENTRY_QUESTIONS — MAX 10 ITEMS, DISCRIMINATED ON TYPE

single_select / multi_select

{ id, prompt (≤200 chars), type, required, options: [{ value, label (≤120 chars) }, 1–20 items, unique values] }

short_text

{ id, prompt (≤200 chars), type, required }

id pattern: ^[A-Za-z][A-Za-z0-9_-]{0,63}$, unique within the array.

CREATE-TIME LOCATION INPUT — DISCRIMINATED ON MODE

anywhere

no fields

fixed_location

{ location, radius_meters (30–2000, default 100) } — location is either a simple form (address and/or place_name and/or lat/lng, resolved server-side) or a pre-resolved form (full payload from a prior resolve_location call)

city

{ city (1–120), state_code, country_code }

zip_code

{ zip_code (5-digit), country_code }

STORED / NORMALIZED

fixed_location stores a full resolved payload — { lat, lng, friendly_location_name, formatted_address, location_provider, provider_place_id, apple_map_item_identifier?, location_resolution_confidence, google_place_id? }. city/zip_code store an Apple scope object instead:

location_scope: { schema_version: 1, provider: “apple”, provider_place_id, country_code, display_name, map_label, center: {lat,lng}, display_region: {south_latitude, west_longitude, north_latitude, east_longitude}, type, state_code, city }

(or zip_code in place of city for the zip variant). Immutable once resolved — quote/create resolve city/ZIP input to this before activation.

COUNTRY CODE, IN FULL

Two Fields, No Curated List

Location country_code (fixed_location’s address input isn’t affected; only city/zip_code modes take this) — hard-locked to exactly one live value: “US”. The Zod schema literal-matches US only; nothing else is accepted. This is a true closed set of one, not a placeholder — Huint’s location resolution only covers the US today.

eligible_country_code (the task’s tasker-eligibility gate) — not a curated list. Both this field and the tasker’s own taskers.country_code are format-checked only (^[A-Z]{2}$, uppercase ASCII letters) at the database level; eligibility is decided by simple string equality between the two (private.tasker_eligibility_verdict). An operator can type any syntactically-valid 2-letter code (e.g. CA, GB) and it will be stored and matched — there’s no server-side check against a real ISO-3166 list or against where Huint actually operates. If the iOS app’s own country picker restricts what a tasker can set on their profile, that would be the only real-world limiter, and it lives outside this backend/MCP surface.

Related: state_code in the location-scope input is likewise format-checked only (^[A-Z]{2}$) — real validation happens implicitly when Apple’s geocoder fails to resolve a bogus state.

submission_status (3)

pending, verified, rejected

submission_rejection_reason (5)

unclear, wrong_subject, framing_or_angle, suspected_reuse, policy_violation — agent-judgment only; GPS/device/timestamp/photo-count fail automatically and never touch this enum

held_too_long, hand_abandoned, rejected, reported, admin_block

TASK_BLOCKLIST — WHO CAN’T RE-CLAIM A GIVEN TASK

task_id / tasker_id

uuid

composite scope

reason

text

5 live values, in the enums table above

claim_id

uuid

the claim that caused the block, if any

created_at / acknowledged_at

timestamptz

—

A reject blocks one tasker from one task — it doesn’t touch their account standing anywhere else.
