Preserve partial-pricing status for Pi responses.
When scan_pi() finds an unpriced model, this route returns a numeric total_usd without modelPricingCompleteness, coverage, or a known-cost indicator. A client cannot distinguish a complete Pi total from a partial estimate. Emit the shared spend-contract pricing fields, or mark the total as unknown when pricing is incomplete.

Include Pi scan evidence in Claude coverage.
scan_pi_compatible_into now returns PiScanEvidence, but this caller discards it. If native Claude files scan successfully while a Pi/OMP file has a malformed usage row or read failure, finalize_claude_summary marks the combined result as complete. Consumers can then present a partial total as authoritative.
Capture PiScanEvidence::complete. If it is false, clear history_coverage_established and known_zero after finalization.

Preserve path case on case-sensitive filesystems.
This code lowercases every canonical root. On Linux, two distinct roots such as /data/Pi and /data/pi then share one deduplication key. The scanner omits the second root and undercounts its sessions.
Apply case folding only on Windows. Preserve the canonical path on other platforms.

Pi is an alternate local-history view over rows that may also be compatible with Codex or Claude. Combined selections assign those rows to the standalone Pi source, while shared Overview excludes the Pi alternate row to avoid double counting.
Persistent upstream artifact-v9 cache, project or account attribution, and broader process-context retention remain deferred for a follow-up.
