- 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.

The parser is pure Go but a goroutine cannot be killed, so extraction runs in
a child process: the binary re-executed as `sift pdftext`, reading the PDF on
stdin and writing JSON Lines on stdout, killed at a deadline by the parent.
pdftext.go holds the types, the five errors, Extract (reader.Open with
ErrWrongPassword -> ErrEncrypted, per-page recover, trailer /Info /Title, and
rule-3 UTF-16BE/Latin-1 text decode) and ChildMain (soft 768 MiB memory limit,
-no env read, no network, exit codes 0/3/4/1). outline.go walks /Outlines ->
/First -> /Next with /First children at level+1, resolving /Dest and /GoTo /A
dests to 1-based pages, bounded at 10,000 items and never visiting an object
twice. runner.go is the Runner: env-isolated child (nil env is an empty
environment), 60 s deadline, 64 MiB output cap, 200 MiB stdin cap, stderr
capped at 4 KiB, exit-code to error mapping, and Doc parsing with ErrNoText.
cmd/sift/main.go adds the unlisted `pdftext` case. tools.go is removed; the
go-pdfkit modules stay vendored.
