Compile selected D&D Beyond character fields into deterministic values, canonical trust states, provenance, unsupported/unknown findings, and lint. This is partial read-only context, not complete rules validation. Input: exact public DDB character URL or id.

Pre-combat context with canonical assessment. Observed hand/equipment state requires player or session-host confirmation.

Run the 100-question extraction Coverage Inventory. Every answer carries its question and closed trust state; this is not a validity score.

Classify the supported subset of changes between a supplied CharacterSnapshotV1 object and a freshly observed public character. No mutation is applied and unclassified changes are named.

Observe a public character once and return a privacy-filtered, versioned CharacterSnapshotV1. Account identifiers, linked images, and persona are omitted.

Privacy-minimized read-only character context. Persona is never exposed; mutable player-authority state is marked rather than treated as host truth.

Read-only settlement and sheet-specific finding prompts. Expected answers exist only for canonical trusted fields; mutable or uncertain fields remain null.

Canonical trust and field assessments plus unhandled and lint findings.

One pre-session packet: supported-coverage state, the exact questions to resolve before dice (each with the family it unblocks), unsupported content, the fields that are the player's to declare, and a baseline-snapshot hint.

Check the offline installation against a bundled sample character — no network, no D&D Beyond account, no character required. Run this first when bootstrapping: it separates 'the tool is broken' from 'I cannot reach that character'.

Diagnose why it is not working: python, DNS, outbound HTTPS, and (with a ref) reachability of that character. Each check reports PASS/FAIL and the first failure carries the remedy.
