The summarization runs server-side, but the SPA held the job only in
component state and jobs lived only in memory — so navigating away from
the Book Summarizer reset the UI (losing the handle to a still-running
job) and past summaries vanished on restart.
- PdfJobDb: SQLite store (its own file under ARCHIVE_DIR) persisting
every job on each progress update.
- JobStore: createdAt, persist-on-update, viewOf()/list() that serve
live jobs first then fall back to the durable record; non-live jobs
whose worker died surface as a new "interrupted" status.
- routes: GET /v1/pdf-jobs (newest-first list); GET /:id + summary.md
serve past jobs via viewOf; /:id/events sends a single terminal frame
for a finished/past job (no hang) and live frames otherwise.
- SPA: RecentJobs list (open any job → reconnect to live progress or
show result), localStorage resume of the active job on return, and a
"back to list (keeps running)" affordance.
- mainnet buyer compose: persistent named volume + ARCHIVE_DIR so the
archive + pdf-jobs.db survive container recreation/redeploys.
Tests: persistence-across-restart, interrupted detection, list, and
past-job serving (incl. terminal SSE). Full buyer suite green (185).

Adds an authenticated upload flow to the buyer web app: an operator
uploads a PDF, the server extracts + paragraph-aligned-chunks it
(~2.2k tokens), then runs a hierarchical map-reduce summarization by
paying marketplace suppliers per chunk — one on-chain escrow per map
call and per reduce node. One book upload fans out into dozens of real
mainnet escrows (the intended marketplace traffic) while producing a
genuine full-book summary.
Server module (buyer/src/pdf/): PDF extraction (text-only, rejects
scanned), token-aware chunker, supplier discovery/round-robin filtered
to capable models (kimi/deepseek/gpt; excludes qwen2.5:0.5b), pre-spend
cost estimate + wallet-floor guard, and a JobStore orchestrator that
reuses submitPrompt → findSubmittedEscrowRef → runAccept per call.
v1 serializes PostEscrow under a mutex (the shared tx builder can't pin
wallet inputs, so parallel escrows would double-spend); retries failed
calls on a different supplier then continues with gaps. 6 /v1/pdf-*
routes (multipart upload, estimate, confirm-gated start, SSE progress,
result, .md download) behind the existing session auth + page/chunk/
balance caps. SPA adds a 4-step BookSummarizer wizard.
Tests: chunk/estimate/supplier-pool/extract unit tests + orchestrator
(happy/gap/failover) + routes integration. Full buyer suite green
(181 tests); SPA build + typecheck clean.
