# EPCIS multi-node privacy + authorization smoke test (slice 06).
#
# Boots a 6-node devnet (or reuses an already-running one), provisions
# a curated EPCIS context graph with explicit publisher authorization,
# and runs eleven scenarios that empirically verify the privacy +
# async-publish contract end-to-end across publisher / allowed-peer /
# unauthorized-observer roles.
#
# Topology:
#   N1 = publisher        (capture origin, on-chain CG curator)
#   N2 = allowed peer     (receives allow-list private payload via P2P)
#   N3 = unauthorized obs (subscribed to public partition only;
#                          publish attempts must be rejected on-chain)
#
# 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.
#
# Usage:
#
#   ./scripts/epcis-smoke-test.sh
#
# Env overrides:
#
#   FINALIZE_TIMEOUT=120  Max seconds to wait for terminal capture state.
#   SYNC_TIMEOUT=10       Max seconds for sync ops (subscribe, query).
#   N2_SYNC_TIMEOUT=30    Max seconds to wait for P2P allow-list sync to N2.
#   CG_SLUG=epcis-test    CG slug (final id is auto-namespaced under N1's
#                         agent address: <N1.agentAddress>/<CG_SLUG>).
#   KEEP_ARTIFACTS=1      Preserve /tmp/epcis-smoke-* docs after success.

  # turns to `failed` with a chain-level auth diagnostic in `failure.message`.
  # Empirical reality on this codebase has TWO gates that can fire:
  #
  #   - Network-layer gate (daemon 404 ContextGraphNotFound). The CG was
  #     created with `accessPolicy: 1, allowedAgents: [N1, N2]`. N3 is not in
  #     the participant list, so its CG-meta sync request is denied by the
  #     curator (see `request-authorize.ts`). N3 therefore has no local view
  #     of the CG, and `/api/epcis/capture` rejects with 404 before any
  #     chain interaction.
  #   - Chain-layer gate (state=failed with "No authorized publisher wallet
  #     found in signer pool"). Would fire if N3 were locally subscribed but
  #     not on-chain authorized — but with the current CG-level participant
  #     model, "locally subscribed" implies "on-chain participant", so this
  #     branch is unreachable on this CG.
  #
  # The spec's intent is to verify "the chain auth gate is real and not
  # silently no-op'd." The chain auth gate is independently verified at
  # preflight (the `on_chain_is_authorized($CG_ON_CHAIN_ID, $N3_PUBLISHER_WALLET)
  # == false` check). Scenario 11 therefore verifies the runtime gate at
  # whichever layer fires first: a 404 ContextGraphNotFound, or a
