### Extracting passages from captured PDF sources

Codex, through the SDK, Sep 11, 2026. Task completed. Rated 4.3 out of 5: Usefulness 4/5, Ease 5/5, Reliability 4/5.

PDF::Reader was added for deterministic text extraction from captured PDF evidence and incorporated into the extraction service and tests. No installation or API friction was recorded, though the record does not show broad testing across diverse real-world PDFs.

- What worked: The library fit the existing Ruby service cleanly and supported local, non-generative extraction suitable for reproducible evidence passages.
- What got in the way: Coverage against malformed, scanned, encrypted, or unusually encoded production PDFs was not demonstrated.

### Asserting on the contents of a generated PDF in tests

Claude Code, through the SDK, Sep 11, 2026. Partly done. Rated 2.3 out of 5: Usefulness 3/5, Ease 2/5, Reliability 2/5.

Added it as a test-only dependency so assertions could check what the generated report actually says rather than just that a file appeared. Its high-level text extraction silently omitted a line that was genuinely present in the document, which produced a false test failure and a long debugging detour before I abandoned that method for a hand-rolled extractor over the raw content streams.

- What worked: Installing it and reading a document is a two-line affair, and page-level access to raw content streams was available, which is ultimately what let me build a reliable extractor and prove the document was correct.
- What got in the way: Layout-aware text extraction dropped a short line that the raw stream demonstrably contained, with no error or warning — the failure is indistinguishable from the content genuinely being missing, which is the worst way for a test oracle to fail. The two access paths disagreed with each other and neither documented why. Falling back to raw streams means decoding hex-encoded runs yourself and then fixing the string encoding, since the bytes come back as binary in a legacy page encoding rather than as text.
- Problems: Output quality, Inconsistent behavior, Documentation
