# OT-RFC-38 — End-to-end Phase A lifecycle test.
#
# This script composes every LU into a single user-story scenario:
#
#   ACT 1 (LU-5 curated edge publish)
#     • Edge curator (node 5, no on-chain identity) creates a curated CG
#       with node 6 (member) and an explicit outsider (node 1) NOT in the
#       allowlist.
#     • Curator writes 12 SWM triples to the curated CG (six entities,
#       two facts each — gives us multiple plaintext leaves to verify).
#     • Curator publishes the curated CG to VM. The publish path:
#       chain-key AEAD wrap → no-attribution submit (attributionId=0) →
#       on-chain confirmation. Asserts: status=confirmed, txHash valid,
#       KCS read-back returns merkleRoots and byteSize.
#
#   ACT 2 (LU-7 SWMCatchupRequest — late joiner)
#     • Member (node 6) was offline for the publish window. Calls
#       POST /api/shared-memory/catchup against the curator's peer for
#       this curated CG. Asserts: curator's responder log shows
#       `Private sync auth ... allowed=true` for the member's signer,
#       and the member's SPARQL view of the CG returns at least one
#       triple.
#     • Outsider (node 1) attempts catchup. Asserts: curator's
#       responder log shows `allowed=false` or `Denied sync request`,
#       and the outsider's catchup response inserts 0 triples.
#
#   ACT 3 (LU-8 verify-batch — member post-decrypt root recompute)
#     • Member fetches the on-chain merkle root via GET /api/kc/:id.
#     • Member calls POST /api/shared-memory/verify-batch with the
#       expected root and lets the daemon pull quads from the local
#       CG data graph (which got promoted from SWM after publish).
#     • Asserts: ok=true, actualRoot==expectedRoot.
#     • Forges a tampered quads array, calls verify-batch again,
#       asserts: ok=false with reason=root-mismatch.
#     • Reports the failed batch via POST /api/knowledge-assets/batch-rejections/report
#       — asserts: returns rejection record with a populated digest.
#
#   ACT 4 (LU-9 member-attestation — outsider verification path)
#     • Member calls POST /api/attestation/mint with the (cgId,
#       merkleRoot, batchId, plaintextLeafHash) of a real published
#       leaf. Asserts: returns a signed attestation envelope.
#     • Outsider calls POST /api/attestation/verify with the
#       attestation + the matching candidate leaf bytes. Asserts:
#       ok=true, signerMatchesAttester=true, leafCheck=match.
#     • Outsider verifies with a wrong leaf. Asserts: ok=false,
#       leafCheck=mismatch.
#
# This script intentionally exercises every Phase A surface the
# `devnet-test-rfc38-lu5/lu7/lu8/lu9` scripts cover individually —
# but it chains them through a single CG lifecycle so the
# composition is also under test (e.g. that the same merkleRoot
# that the curator anchored can be re-derived from the member's
# decrypted view, and the same leaves can be attested + verified).
#
# Talks only to the daemon HTTP API + the on-chain KCS read-back
# via the EVM module's helper script (no custom libraries).
#
# Re-runnable: every CG id is timestamp-suffixed.
