README gains API, CLI and configuration sections and the PDF range/grep/question limits; the skill covers PDF busy and failure results; dist/sift.service matches the Nix unit (MemoryMax=1G, secret.env); the example config drops the unused [upstreams] block; stale task comments in api/pdf.go.
Gate overridden by the owner: TestGrepLimits (given test) exceeds its 1 s budget under -race on this host.

- pdftext/outline: resolve named destinations through the catalog /Dests and the /Names /Dests
tree, resolve indirect /Dest, /A and /Title, and treat reader.Null (what Dict.Get returns for
a missing key) as absent. Before this every LaTeX and Acrobat PDF had an empty outline.
pdftest gains NamedDests; TestOutlineNamedDestinations.
- api: pool() always goes through its Once (data race on concurrent first use);
TestDefaultPoolConcurrentFirstUse. Revalidation of a stale cache entry counts against the
caller/host limit.
- pdftext/runner: output over MaxText kills the child at once instead of waiting for the
deadline; TestRunnerTooMuchTextFailsFast.
- fetch: Accept includes application/pdf;q=0.8.

Digest systemPrompt gains a page-cite instruction and PromptVersion is 3.
Add the sift_pdf_* metric series (extract_total{outcome}, extract_seconds,
pages_total, pool_wait_seconds, cache_hits_total) to internal/metrics and wire
ObservePDF/ObservePDFWait/PDFCacheHit into internal/api/pdf.go. Refactor
cmd/sift/fetchcmd.go to a fetchOpts struct with parseFetchOpts and fetchBody,
adding --pages/--grep. Update skill/SKILL.md, set nix MemoryMax to 1G, and add a
PDF documents section to the README.

Answer extracted PDFs from the document cache: fresh for PDFTTL, then a
conditional GET (304 reuses the stored text, a 200 is extracted and stored
without a second GET). Store after extraction with the response hash, ETag,
fetch time and extracted pages. Route pages/grep through pdfdoc.Options with
400s for bad ranges and non-PDFs, and refuse a question when the document
exceeds PDFMaxQuestionChunks with a pointer to grep and pages.

Route "pdf" through clean.Kind in doFetch/cleanFetched: extract under the pool
(keyed by caller class + document hash, one per caller), map the five pdftext
errors plus a pool panic to 422, ErrBusy to 503+Retry-After 10, ErrCallerBusy to
429, and answer with the whole text or the map. Adds RetryAfter to fetch.Error
and the matching header. No cache, pages or grep — those are task 07.
