A PDF build step you can rely on

CompilePDF assembles and rewrites print-ready PDFs over a simple API — every byte deterministic, every operation verifiable, with SHA-256 lineage. AGPL-3.0-licensed, no vendor lock-in.

Rewrite producer

Fifteen object-tree mutations across structural, hygiene, and lifecycle categories. OCG flips, page boxes, metadata patches, color-space swaps — every op round-trips deterministically.

Marks producer

Twelve mark types across production, proofing, and universal categories — register, crop, color-bar, fold, slug-text — plus PDF/PNG external template ingestion.

Impose producer

Sheet-level step-and-repeat with work-and-turn / tumble. Codex solves the layout via tile_grid; Compile drops cells via pikepdf. Cell-extract round-trip verifier in CI.

Trap producer

Ink-pair spread / choke with three engine slots (pure_python default, ghostscript, external). Codex polygon_offset + delta_e_2000 verification. trap-diff artifact baked in.

CJD batch jobs

Compile Job Definition envelopes — JSON and XML — batch several operations (rewrite, marks, impose, trap) into one API call. Canonical step ordering; strict_order rejects out-of-spec.

Lineage chain

One record per producer step, threading input/output SHA-256 + cache_key through the chain. Memory backend default; S3 + Redis lit up for durable storage.

Four-layer verifier

Every producer ships post-condition gates: schema, determinism, nothing-else-touched, plus a producer-specific Layer (marks-hash, cell-extract, delta_e tolerance).

Deterministic by construction

Pdf.save(deterministic_id=True), no wall-clock time inside engines, fixed-decimal numeric formatting. Same input + same plan → same SHA-256 across machines.

Cache-key reproducibility

Cache keys composed from codex_pdf wheel version + color/geom/document schema versions + producer + plan SHA + input SHA. Section bumps invalidate automatically.

Real ink-pair extraction

trap-extract walks PDF content streams, finds spot-ink rectangles, and emits suggested trap_zones for every adjacency. Auto-trap pipelines stop being manual.

Auth on every route

COMPILE_AUTH_MODE gates producer + CJD + lineage endpoints (bearer / api-key / internal / basic). Healthz / contract / version / metrics stay open by design.

Celery-ready

Five Celery task wrappers (one per producer + CJD). Workers run via `celery -A compile_pdf.tasks worker`; /v1/healthz.celery_workers surfaces live count.
