Canonical pricing core and schema extraction

Extract a reusable adaptive-pricing core from the Coulomb observatory MVP and define the canonical pricing-model schema needed by the later milestones.

Define Canonical Pricing Schema

id: ADAPTIVE-WP-0003-T01
status: todo
priority: high
state_hub_task_id: "c79647e3-f760-4a2f-ae45-a3532692a3d3"

Define the repository's canonical pricing-model schema and parameter taxonomy. Cover charge components, commitments, tunable parameters, calculated fields, eligibility, lifecycle metadata, and provider-mapping hooks.

Extract Generic Pricing Core

id: ADAPTIVE-WP-0003-T02
status: todo
priority: high
state_hub_task_id: "2d27616b-ea0c-4600-b7a2-eb5a22932b58"

Refactor the current Coulomb-specific observatory modules so generic pricing logic can live outside project-specific deployment code. Preserve Coulomb as the first adopter of the extracted core rather than leaving the core trapped inside projects/coulomb-pricing/observatory/.

Implement Schema Loader And Validator

id: ADAPTIVE-WP-0003-T03
status: todo
priority: high
state_hub_task_id: "6fa1ee8f-27ae-45b3-bd98-ea2a4873c0c8"

Implement loading and validation for the canonical schema, including structural checks, required-field rules, and scenario tests for flat, hybrid, and commitment-backed models.

Migrate Coulomb Pricing Registries

id: ADAPTIVE-WP-0003-T04
status: todo
priority: medium
state_hub_task_id: "fed8cb44-4219-4b7f-b641-90d872ebc285"

Migrate projects/coulomb-pricing/data/pricing-models.json and related loading paths so the Coulomb observatory uses the canonical schema without losing existing dashboard behavior.

Exit Criteria

id: ADAPTIVE-WP-0003-T05
status: todo
priority: medium
state_hub_task_id: "77305962-6f56-44aa-a8e4-32cfc5de262b"

Exit when the repo has a documented canonical schema, a validator with tests, and a working Coulomb observatory instance backed by the new internal model.
