  Code Spire contains no PR-Agent source code. PR-Agent was read as prior art
  during design, at tag v0.38.0 (published 2026-06-26, Apache License 2.0 at that
  tag). The shipped code was compared against that tag's source on 2026-07-26;
  the full side-by-side is docs/RESEARCH.md section 4.

  What the two codebases share, in full:

    1. The prompt hunk markers "__new hunk__" / "__old hunk__" and a
       "## File: '<path>'" header, in spire-diff DiffRenderer. Short functional
       identifiers forming a format convention agreed with the model.

    2. The numeric constant 0.9 as a safety factor before clipping, in
       spire-diff TokenBudget. Applied to a character-ratio estimate here; to a
       real tokenizer count upstream.

  Everything else differs, including every part a reader might assume was taken:
  the diff layer is a typed FilePatch/Hunk/DiffLine model rather than upstream's
  string-to-string patch rewriting; token counting uses a chars-per-token
  heuristic rather than a tokenizer; the model output contract is JSON parsed
  with Jackson rather than YAML repaired by try_fix_yaml; and the prompts in
  spire-contract PromptCatalog are written here, with a different output schema,
  a different severity scheme, prompt-injection fencing that upstream has none
  of, and two prompt kinds (RECONCILE, FOLLOWUP) that address problems a
  single-shot reviewer does not have.

  What PR-Agent contributed was knowing which problems are real: that hunk
  parsing must track both sides' line numbers, that multi-file diffs need
  budgeting rather than arbitrary truncation, and that model output is reliably
  almost-valid and must be parsed defensively. Those are observations, not
  expression. Credit is recorded here because they are worth crediting, not
  because a licence requires it.
