G_Q2 Lean cleanup - Claude Code session logs (sanitized extraction)

Unlike the formalization archive (full transcripts, lightly redacted),
this archive follows the published-record policy of the development
record at https://roed314.github.io/gq2/development/:
  * assistant messages only - no human text, no tool payloads, no
    hidden thinking
  * local absolute paths -> [local path]; scratch paths -> [private
    compute path]; local session ids -> [private session id]
  * personal and collaborator email addresses -> [redacted-email]

Scope: 7 sessions of post-formalization Lean cleanup and axiom work
on the gq2-lean repository (2026-07-11 .. 2026-07-24).
Format: one JSON object per line (JSONL); each file is one Claude
Code session, named by the session UUID prefix; fields are model,
phase, role, text, timestamp (UTC).
