Keshav Three-Pass

Read one paper in three passes of increasing depth. The outputs accumulate as prose rather than fixed fields; use a different tactic when cross-paper alignment matters more than understanding.

Orchestration Pattern

1. Call paper-fetch with paper_ref. Stop on not_found. Create context/papers/<dir>/keshav-three-pass/ on success.
2. Call first-pass-skim with source_path and meta_path. Write 01-first-pass-skim.md, recording read_deeper in frontmatter.
3. If read_deeper is false, stop by default. Continue only on explicit caller override and record gate_overridden: true.
4. Call second-pass-grasp with the paths and skim_notes; write 02-second-pass-grasp.md.
5. Call third-pass-deep-read with the paths and grasp_summary; write 03-third-pass-deep-read.md.

Do not collapse pass 3 into a recap of pass 2. It must surface implicit assumptions, virtual re-implementation mismatches, and concrete improvements.

Output Layout

context/papers/<timestamp>-<title-slug>/
  source.md
  source.meta.json
  keshav-three-pass/
    01-first-pass-skim.md
    02-second-pass-grasp.md
    03-third-pass-deep-read.md

Each output carries sop, tactic, and written_at frontmatter. Report the gate outcome, core claim, most consequential implicit assumption, unresolved flags, and all output paths.
