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.

Adds an Express requireAuth middleware on /v1/* + the SPA shell and a
Vite/React login screen so anyone who reaches mp-buyers.* must authenticate
before driving the operator's wallet via /v1/submit-prompt or /v1/accept.
Why: the buyer-app sits on a public HTTP port and signs txs with a
server-held private key. Until now the only gate was network reachability.
Mechanics:
- BUYER_PASSWORD + SESSION_SECRET (>=32 chars) loaded by config.ts and
surfaced as createApp() deps. Production refuses to start without both.
- buyer/src/auth.ts: HMAC-SHA256 signed buyer_session cookie (HttpOnly,
SameSite=Lax, Path=/, optional Secure), 7-day rolling expiry,
timing-safe password compare, in-memory 5/15-min per-IP rate limiter.
- /v1/auth/{login,logout,whoami}. Login is rate-limited; 6th wrong
attempt returns 429 + Retry-After. Success resets the bucket.
- SPA boot block (__BUYER_BOOT__ injected by server.ts) is gated by the
same cookie so the buyer's address never reaches an unauthenticated
browser.
- New <AuthProvider>/<RequireAuth> in buyer/src/ui/state/AuthContext.tsx
probes /v1/auth/whoami on mount and a scoped window.fetch patch drops
to the login screen on any mid-session 401 from /v1/* (excluding
/v1/auth/* so wrong-password 401s stay local to <Login>).
- Tailwind login card at buyer/src/ui/pages/Login.tsx. App.tsx wraps in
<RequireAuth> and adds a "Sign out" button in the nav.
Tests: tests/unit/buyer-server-auth.test.ts covers sign/verify, rate
limiter, cookie helpers, login flow (400/401/204/429), whoami
(no-cookie/valid/tampered/expired), rolling renewal, logout, gated
/v1/*, /healthz still open, and the no-auth-deps construction shape.
Updated buyer-server-config + buyer-ui-smoke for the new required env
vars and the AuthProvider wrap.

When ESCROW_REF_UTXO / ADVERT_REF_UTXO env vars are set (format
<txhash>#<idx>), Claim/Submit/Accept/Reclaim/RetireAdvert call
.readFrom([refUtxo]) instead of inlining the validator CBOR via
.attach.SpendingValidator(). Lucid-evolution 0.4.30 auto-extracts
utxo.scriptRef into the script-witness map (dist/index.js:1903–1913),
so no separate attach call is needed. Default (env unset) is unchanged.
Adds buildLiveTxForPublishReferenceScripts (a one-shot tx that
publishes both validators as scriptRef-bearing UTxOs at a caller-
supplied address — typically the all-zero-pkh enterprise burn address)
and the supplier tx:publish-reference-scripts CLI that wraps it.
Targeted at testnet trial; mainnet rollout is a separate flip after
verification.
