Prove Stelae publisher host parity

[scarmuega]

Plan: plans/stelae-publisher-pipeline-stelae-parity.md

Summary

• pin a redistributable 4,958-block Preview fixture crossing the first epoch boundary and the immutable Dolos old-host revision
• compare old/new host replay, canonical directory and OCI publication, transfer accounting, force-rebuild reproduction, no-op policy, and unchanged-consumer restore
• add dedicated real-parity and Docker fault/restart CI lanes plus an uploaded JSON parity report
• expose repository transfer counters in the new publisher outcome and CLI report

Verification

• cargo test --offline --workspace --all-features
• STELAE_PARITY_NEW_REVISION=47b38a4 STELAE_PARITY_REPORT=target/publisher-parity.json cargo test --offline -p stelae-cardano --test publisher_parity -- --ignored --nocapture
• cargo test --offline -p stelae --all-features --test oci -- --ignored --nocapture (16 Docker-backed cases)

Old host: Dolos 1ae4e91c18a9e1456a3612af402d7b9b97546d30
New-host base: Stelae 47b38a4

📝 Walkthrough

Walkthrough

The change adds a pinned Cardano Preview replay fixture and an ignored old/new publisher parity test. It compares directory and OCI publication, restores through the unchanged consumer, reports transfer metrics, documents the parity gates, and runs them in Ubuntu CI.

Changes

Publisher parity

Layer / File(s)	Summary
Pinned replay fixture and test dependencies stelae-cardano/Cargo.toml, deny.toml, stelae-cardano/tests/fixtures/preview-epoch-0/*	Adds pinned Dolos test dependencies, the dependency-policy allowance, and Preview genesis, protocol, and 4,958-block replay fixture data.
Replay, publication, and restoration parity stelae-cardano/tests/publisher_parity.rs, stelae-cardano/src/publisher.rs, stelae-publisher/src/main.rs	Adds ignored parity coverage for replay, directory and OCI publication, restoration, registry behavior, identity and inscription equality, and transfer metrics. Repository publication outcomes and CLI output now include transfer statistics.
Parity gate automation and documentation .github/workflows/ci.yml, docs/publisher-parity.md, docs/publisher.md	Adds Ubuntu jobs for publisher and OCI parity tests. Documents pinned inputs, checks, reports, measured results, local registry coverage, and the parity evidence link.

Merge Risk: 🟡 Moderate · up to 7d972

The new parity gate can pass while its checked-in genesis fixtures differ from the configuration actually used for replay. Tie replay to those fixtures, or compare parsed configurations, before relying on the gate.

In `@stelae-cardano/tests/publisher_parity.rs`:
- Line 159: Update the parity setup around read_fixture and the genesis
initialization so replay uses the checked-in genesis fixtures rather than only
dolos_cardano::include::preview::load(). Ensure the four fixture files’ parsed
values are used or validated against the embedded Preview genesis before running
the old host, new host, and restore paths, while preserving the existing hash
verification.
