kyleandornith-1.5-35b-a3b b93b7d5816 dcache: PDF document cache (per URL and caller class, whole-document eviction)
Add pdf_doc/pdf_page tables plus PDFEntry, PDFKey, PutPDF (one transaction,
old pages deleted first), GetPDF (page-ordered, updates last_hit) and TouchPDF
(304 revalidation moves only fetched_at). PDF documents count toward Size() and
are evicted whole by oldest use; PDFH/PDFM counters added. evict() now breaks
last_hit ties by rowid so same-second inserts evict in insertion order.

Task Date Status Sessions Gate Deviations Summary
p5a/01-kind-fetch 2026-09-25 done resumed gate: ok none Implemented Kind/application/pdf recognition, PDF body cap (100 MB) and deadline (120 s), and FetchIf with If-None-Match/If-Modified-Since via shared doFetch. Previous session could not pass TestFetchIf only because the given test held its mutex across the handler (deadlock); owner fixed the test. Session resumed after that fix — did not rewrite fetch code, only verified rules and ran gate.
p5a/02-pdftext 2026-09-25 done 1 gate: ok none Built the child-extraction package: Extract (reader.Open with ErrWrongPassword→ErrEncrypted, per-page recover, trailer /Info /Title, rule-3 UTF-16BE/Latin-1 decode), outline.go (/Dest and /GoTo /A dests, 10k-item and no-double-visit bounds, never-nil outline), Runner (re-exec'd child, env-isolated via empty env, 60 s deadline, 64 MiB output cap, 200 MiB stdin cap, stderr capped at 4 KiB, exit-code→error mapping, Doc parse plus ErrNoText), and the sift pdftext case in main.go. Removed the tools.go module pin; go.mod/go.sum/vendor/modules.txt confirmed unchanged. All 10 given tests pass under -race -count=3 including the deadline-kill test; make gate ok; given files byte-identical; `printf nope
p5a/03-dcache 2026-09-25 done 1 gate: ok evict() tie-break Added the pdf_doc/pdf_page tables, PDFEntry/PDFKey/PutPDF/GetPDF/TouchPDF (one-tx write deleting old pages first, page-ordered read, 304 touch moves only fetched_at), PDFH/PDFM counters, Size() including pdf_doc nbytes. One deviation: extended the eviction union with pdf_doc and added rowid ASC to the ORDER BY so same-second puts evict in insertion order (deterministic whole-document eviction); without it TestPDFEviction is order-dependent. Left Stats() signature unchanged for task 07. Given test byte-identical.
