+# EPCIS-on-DKG Demo — Acme Bikes Assembly Line W18
+
+A practical, end-to-end walkthrough of the v10-rc EPCIS plugin against synthesized supply-chain data. One bicycle, 7 station events, full privacy story.
+
+## What this is
+
+**Acme Bikes** is a fictional bicycle manufacturer used here to keep the demo grounded in something readable while staying free of any partner data. Their **Assembly Line W18** produces road bikes. Each bicycle passes through 7 stations (frame welding, painting, wheel assembly, drivetrain, paint inspection, functional test, packing) before shipping. Every station emits a structured event — which item, where, when, status — that maps directly to the GS1 **EPCIS 2.0** supply-chain standard.
+
+This demo follows **one bicycle** (`trace_id 7c4f8d2a-9e3b-4a6d-b517-8f9e0a1b2c3d`, item `BIKE-2026-W18-0001`) through the line. It captures every station event with the v10-rc EPCIS plugin, queries the data back, and shows what each party (Acme owner, granted research lab, external auditor, competitor) can see at each step.
+
+The privacy story is the central beat: by default, EPCIS captures publish a **public anchor** (proves the event happened) plus a **private payload** (full event body, locally readable, optionally granted to specific peers via allowList). The demo demonstrates this contrast on synthesized data that's safe to commit and replay in any environment.
+
+## Prerequisites
+
+- Node.js 22+ — matches the repo-level requirement (`README.md:70`). The demo also uses built-in `fetch`, which is stable from Node 18 onward; the 22 lower bound here is set by the repo, not the demo itself, and is enforced when you run `pnpm -C packages/cli build` from the next bullet.
+- Local DKG daemon running and reachable on `~/.dkg/api.port`. Start it with `dkg start`.
+- Either a recent `dkg` on your `$PATH` *with* the `epcis` subcommand, **or** the local CLI build (`pnpm -C packages/cli build` from repo root). `run.mjs` prefers the local build automatically.
+- The local devnet must be in a **healthy** state — chain adapter responding, contracts deployed and in sync. If the devnet has been running across contract redeploys, captures will finalize with `Async lift cannot mark chain inclusion`. Stopping and restarting the daemon (`dkg stop && dkg start`) typically resolves this; see commit `27490f2b fix(devnet): redeploy contracts when artifacts outpace running chain` for the underlying fix.
+
+## How to run
+
+Default — paced, narrated walkthrough. Each phase prints its story, then waits for `Enter`. Read at your own speed; the prior phase output stays on screen until you advance.
+
+```sh
+node run.mjs
+```
+
+Unattended (still narrated, but no pauses):
+
+```sh
+node run.mjs --no-pause
+```
+
+Agent-friendly NDJSON mode (one JSON line per phase step, no narrative, no pauses):
+
+```sh
+node run.mjs --json | jq .
+```
+
+Skip context-graph creation (useful when the CG is already registered and you want to skip the daemon round-trip). Skip mode requires `EPCIS_DEMO_CG` to be the **fully qualified** CG ID — bare names exit early with a clear error because the auto-resolution path is bypassed:
+
+```sh
+EPCIS_DEMO_CG=0xabc.../dmaast-bike-demo node run.mjs --skip-cg-create
+```
+
+Override the context graph ID:
+
+```sh
+EPCIS_DEMO_CG=my-test-cg node run.mjs
+```
+
+By default the demo auto-suffixes its CG name with a per-run timestamp (e.g. `dmaast-bike-demo-mz4hk7n0`) so naive re-runs always create a fresh context graph. The ETL produces deterministic event IDs, so re-capturing the same fixtures into an existing CG hits publisher duplicate-root rejection mid-Phase-1 and never reaches the verification phases — so **pinning `EPCIS_DEMO_CG=<name>` does not, on its own, let you iterate Phase 7**. Phase 1 will hard-fail before Phase 7 runs. To iterate Phase 7 against a stable CG you would need a separate "skip-capture" mode (not provided), so the supported workflow is: let the demo create a fresh CG per run. Pin `EPCIS_DEMO_CG` only when targeting a CG whose `bike-line` sub-graph does not already contain these event IDs.
+
+## How to navigate
+
+| What you want | Where to look |
+|---|---|
+| Regenerate fixtures from source data | [`lib/etl.mjs`](./lib/etl.mjs) and [`fixtures/README.md`](./fixtures/README.md) |
+| EPCIS field mapping rules | [`lib/epc-mapping.mjs`](./lib/epc-mapping.mjs) |
+| The synthesized raw source | [`fixtures/source-raw/acme-bikes-line-w18.json`](./fixtures/source-raw/acme-bikes-line-w18.json) |
+
+## What's NOT in this demo
+
+These are deliberately excluded:
+
+- **Multi-node setup.** AllowList grant is *recorded* (Phase 6); cross-node read enforcement uses the same plugin code path but requires a second node to exercise.
+- **Kafka / streaming ingest.** EPCIS is the channel; the upstream wiring is separate.
+- **Real partner data.** The fixtures are fully synthesized — no customer or partner identifiers anywhere. If you want to drive the demo from a real export, you'll need to author your own raw source file with the same shape as `fixtures/source-raw/acme-bikes-line-w18.json` and point `BIKE_SOURCE` at it.
+- **UI integration.** node-ui's Explorer / graph-viz exists; this demo is CLI/API only.
+- **Live-chain hardening.** Devnet-only.

+# Fixtures
+
+Pre-generated EPCIS 2.0 documents from one synthesized Acme Bikes assembly trace.
+
+## Contents
+
+| File | Purpose |
+|---|---|
+| `source-raw/acme-bikes-line-w18.json` | The synthesized raw source — 7 cycle records on the assembly line. Committed because it's fully synthetic; ETL is reproducible from a clean clone. |
+| `event-NN-<station>.json` | One EPCIS document per station event, in chronological order. Each document holds exactly one `ObjectEvent`. |
+| `trace-7c4f8d2a-bike-line.json` | Manifest: trace ID, time range, stations visited, item IDs, plus per-event metadata (eventID, bizStep, disposition, action). |
+| `source-snapshot.json` | Source basename + SHA-256 of the synthesized raw source used at ETL time. |
+
+The Phase 6 allowList grant is demonstrated against a synthesized "shipping" event built in memory by `run.mjs` and written to `os.tmpdir()` per run — no committed file.
+
+## Regenerate from source
+
+The fixtures are generated from the committed synthesized source `source-raw/acme-bikes-line-w18.json`. To regenerate after editing the source:
+
+```sh
+node ../lib/etl.mjs
+
+# or override
+node ../lib/etl.mjs \
+  --source ./source-raw/acme-bikes-line-w18.json \
+  --trace-id 7c4f8d2a-9e3b-4a6d-b517-8f9e0a1b2c3d \
+  --out ./
+
+# or via env
+BIKE_SOURCE=./source-raw/acme-bikes-line-w18.json node ../lib/etl.mjs
+```
+
+ETL is deterministic: same source + same trace ID → identical eventIDs. The seed is `trace_id|unit_id|process_name|ended` for the common case where one source record yields one EPCIS document. `process_name` is part of the seed so per-station cycle counters that share `unit_id` across stations don't collide on the same eventID. When a single source record splits into multiple sibling EPCIS docs (mixed status — e.g. `Passed` vs `Rejected` items in the same cycle — and/or mixed first-seen action — first-seen items become `ADD`, already-seen items become `OBSERVE`), each sibling's seed gains a JSON-encoded `groupKey` segment (`{"status":"...","action":"add"|"observe"}`) so siblings get distinct eventIDs and the publisher's duplicate-root validator can't reject the second one.
+
+## Mapping rules
+
+See `lib/epc-mapping.mjs` for the mapping logic.
+
+- `items.<id>` → `epcList[i]` as `urn:acme:bike:item:<id>` (custom URN — Acme Bikes is a fictional manufacturer; URN segment is normalized by `safeUrnSegment` so spaces / slashes / non-ASCII in source data don't produce invalid IRIs)
+- `process_name` → `bizLocation.id` and `readPoint.id` as `urn:acme:bike:station:<process_name>` (same `safeUrnSegment` normalization applies)
+- `process_name` matching `inspection|test|inspecting` → CBV `inspecting`; otherwise CBV `assembling`
+- `items.<id>.status`: `Passed` → CBV `in_progress`, `Rejected` → CBV `damaged`, `Skipped` → CBV `unknown`
+- `action`: per item, `ADD` for first-seen EPCs in the trace and `OBSERVE` for already-seen EPCs. When a single status group contains BOTH first-seen and already-seen items, the ETL splits the group into separate `ADD` and `OBSERVE` sibling documents (with distinct `groupKey`s) instead of collapsing the whole group to one action — the EPCIS spec reserves `ADD` for true first observations, and the previous "collapse to OBSERVE" / "collapse to ADD" approaches both lost information for one of the sub-groups. For the demo's uniform-status fixture each item appears in exactly one record per station, so the practical pattern is "doc 1: ADD, docs 2..N: OBSERVE".
+- `eventID` derived from `urn:uuid:<v5(trace_id|unit_id|process_name|ended)>` — or `urn:uuid:<v5(trace_id|unit_id|process_name|ended|<groupKey>)>` when a single source record splits into multiple sibling EPCIS documents (see deterministic note above).
+- Source timestamps MUST carry an explicit timezone offset (`Z` or `±HH:MM` / `±HHMM`). Naive timestamps without an offset are rejected at ETL time — `Date.parse` interprets them in the host's LOCAL timezone, which would mis-order records relative to UTC-suffixed timestamps in the same source.

+# EPCIS
+
+GS1 EPCIS 2.0 capture + query plugin on top of the DKG. Maps EPCIS events to RDF
+quads on a context graph, exposes an HTTP capture endpoint and a SPARQL-backed
+events query endpoint.
+
+## Language
+
+**EPCIS Document**:
+A GS1 EPCIS 2.0 JSON-LD document containing one or more EPCIS events. Carried in
+capture requests as `epcisDocument`.
+
+**Capture**:
+The act of submitting an **EPCIS Document** for ingestion via `POST /api/epcis/capture`.
+Async — returns `202` with a **Capture ID**.
+
+**Capture ID**:
+Identifier returned by an async capture, used to poll Lift job state via
+`GET /api/epcis/capture/:captureID`. Distinct from the eventual **UAL** of the
+published Knowledge Collection.
+
+**Context Graph (CG)**:
+The DKG container the document is published into. Required per request — capture
+accepts a `contextGraphId` field; query accepts a `contextGraphId` query param.
+
+**Shared Working Memory (SWM)**:
+Public partition at `<cg>/_shared_memory`. Pre-finalization staging area. For
+private-by-default EPCIS, contains only `dkg:privateDataAnchor "true"` per root
+entity. Authoritative for in-flight (not-yet-finalized) state.
+
+**Finalized partition**:
+Canonical partition at `<cg>` (no suffix). Authoritative durable view —
+populated once a **Capture** completes its publishing cycle and is no longer
+in-flight. Implementation detail: backed by on-chain finalization, but callers
+should never need to know that.
+
+**Private partition**:
+Quads written to `<cg>/_private` (operation-scoped). Holds the actual EPCIS
+event payload when the document is captured privately. Locally queryable on the
+owning node and on nodes in `allowedPeers`. Joined onto whichever public
+partition (**SWM** or **On-chain**) carries the matching root anchor.
+
+**Privacy envelope**:
+Shape `{ public, private }` accepted on capture for explicit split. Bare
+EPCIS Documents go to **Private partition** by default.
+
+## Relationships
+
+- A **Capture** produces a **Capture ID** synchronously and a **UAL** asynchronously once Lift completes.
+- A **Capture** writes to exactly one **Context Graph**, into its **SWM** + **Private partition** by default, or via a **Privacy envelope** for explicit split.
+- Events query targets exactly one public partition per request — **SWM** or **Finalized partition** — selected by `?finalized=true|false` (default `true`).
+- An event is returned when (a) its full EPCIS triples live in the chosen public partition (fully public event), OR (b) the chosen public partition holds a `dkg:privateDataAnchor` for the root AND `<cg>/_private` holds the matching payload (private event). Orphan private payloads — no anchor in the chosen partition — are excluded.
+
+## Flagged ambiguities
+
+- "private" originally meant "envelope split" in PR 376 (bare doc = public). In
+  this context, "private by default" means **whole document → Private partition**.
+  Public partition gets only anchors.

+# Curated CG mode:
+#
+# The on-chain `ContextGraphs.isAuthorizedPublisher` gate has three
+# curator types: EOA / Safe / PCA. Only EOA is exposed via the CLI's
+# `dkg context-graph create --access-policy 1 --allowed-agent` flow.
+# Per `dkg-agent.ts:registerContextGraph` (line ~4373), EOA-curated
+# registration requires `ownerAddress == publishAuthority`, where
+# `ownerAddress` is the curator's local agent address and
+# `publishAuthority` is `chain.getSignerAddress()` (the primary
+# operational wallet). On devnet both resolve to the same node-local
+# publisher wallet (see `agentFromPrivateKey` in agent-keystore.ts:91
+# and `EVMAdapter.getSignerAddress` in evm-adapter.ts:2297), so:
+#
+#   - In EOA mode the storedAuthority is the curator node's wallet,
+#     and `isAuthorizedPublisher(cgId, X) == (X == storedAuthority)`.
+#   - The `participantAgents` list is metadata at the storage layer
+#     in EOA mode — it does NOT grant publish rights. Only the single
+#     storedAuthority is authorized.
+#
+# Therefore:
+#
+#   - N1 is the sole on-chain authorized publisher.
+#   - N2's on-chain auth status is the same as N3's (false) in EOA
+#     mode. The spec's "Authorize N1 + N2 but not N3" is verifiable
+#     only under PCA mode (DKGPublishingConvictionNFT-backed), which
+#     the CLI does not expose. The test deviates here: it verifies
+#     `isAuthorizedPublisher(N1) == true` and
+#     `isAuthorizedPublisher(N3) == false`. N2's allowed-peer role is
+#     exercised via the P2P allow-list payload sync (scenario 8),
+#     which is independent of on-chain publish authorization.
+#
+# Verification (per spec acceptance criteria):
+#
+#   - On-chain auth list checked before scenarios run; abort if
+#     `N1 authorized && N3 unauthorized` is not the truth.
+#   - Per-scenario PASS/FAIL with one-line diagnostic to stdout and
+#     to `docs/epcis/devnet-results-<YYYY-MM-DD>.md`.
+#   - Exit 0 only when all 11 scenarios pass.
