refactor(stelae): consume the stelae crates as a pinned git dependency - #1291
Merged
Conversation
crates/stelae and crates/stelae-driver leave the workspace for github.com/txpipe/stelae (history preserved, lockstep v0.1.0, own CI with the relocated live-registry suite and a cargo-deny boundary ban). crates/snapshot pins both crates to the v0.1.0 tag — the workspace's one pin point. The stelae transport leg leaves registry.yml, AGENTS.md follows, and ADR-004 keeps the Dolos-profile half with the protocol half pointing at the new repository's SPEC.md. Byte-compat: dolos snapshot digest over one seeded store set is byte-identical between main (e7b4642) and this commit. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
📝 WalkthroughWalkthroughThe local ChangesStelae extraction and consumer migration
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to This refactor moves snapshot protocol consumption to a pinned external release and adds a local normative profile, but the profile currently contains contradictory state-namespace counts and unclear retired-schema handling that could cause incompatible validation or restore behavior.

…am's to test Dolos's responsibility is the profile, and the profile is transport-blind: the transport and the publish lifecycle live in the stelae crates, so the registry-integration gate belongs to txpipe/stelae's CI, which already runs the transport round trip against three registry images. The two docker-gated dolos-snapshot suites stay as local verification tools for the composition, no longer a CI obligation. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

…ide its crate The ADR now states the problem and the adoption — context, decision, rationale, limitations, alternatives, and how dolos surfaces the result — and specifies nothing. The normative text splits along the boundary the decision drew: the protocol in txpipe/stelae's SPEC.md, the Dolos profile in crates/snapshot/PROFILE.md, which carries the ADR's implementation half verbatim with section names preserved so older citations land on the same headings. Load-bearing code citations re-pointed. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

In `@crates/snapshot/PROFILE.md`:
- Around line 68-70: Reconcile the state-kind count with the 16 entity
namespaces from build_schema() plus utxos, yielding 17 state kinds. Update the
layer arithmetic and completeness rules, including the four 16-way namespaces
and remaining single-shard namespaces, so the registry, required state-* set,
and documented shard counts agree.
- Line 38: Clarify the restore rules for parameters.schemas: missing entries and
entries with revision 0 represent retired or absent namespaces and must reject
restoring a profile that models them, while positive revision values must not be
gated by revision comparison. Update the paragraph around parameters.schemas and
the restore validation to state this distinction explicitly.

…ing, pin-note the spec link The profile spec (and one state.rs module doc) said sixteen entity namespaces where the code, the coverage test and the ADR's own decision bullet say thirteen — thirteen plus utxos is the fourteen-kind set the completeness check requires. The parameters.schemas gate now reads 'presence, with revision 0 as absence' so the zero-sentinel and the never-compare-revisions rules no longer look like a conflict. The ADR banner notes that the implemented protocol version is the pinned tag, whatever main's spec says since. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
… not optional dolos never built without it: the root crate enabled oci unconditionally, so the feature's only effect was a leaner crate-local dev build and a CI matrix guarding combinations no consumer constructs. The profile now turns the protocol crates' oci transport on in its dependency declaration (the stelae crates keep their own default-off feature for third parties), the cfg gates go, and the snapshot-features job shrinks to the one configuration no workspace job builds: backfill off. backfill stays — it is what makes the root mithril feature able to exclude the mithril-client tree at all.

The extraction itself.
github.com/txpipe/stelaenow holds
stelaeandstelae-driveras a two-crate workspace — historypreserved via
git filter-repoup to and including #1290, lockstepv0.1.0,its own CI (fmt/clippy/test/deny plus the relocated live-registry workflow,
green on the first run),
SPEC.mdas the protocol's normative spec, and acargo-deny bans list that makes "the protocol depends on no profile" a
resolver check.
This PR makes dolos a consumer:
crates/stelaeandcrates/stelae-driverleave the workspace;crates/snapshotconsumes both via one pinned git tag (v0.1.0) — the onepin point, per the re-export seam decision. The stelae-only workspace
dependency entries (
serde_jcs,sha2,zstd,fs4) leave with them;minicborstays forcrates/snapshotwith its pallas-alignment commentreworded.
registry.ymlis retired entirely. Registry interaction — transport andpublish lifecycle — is implemented by the stelae crates, so the
registry-integration gate belongs to
txpipe/stelae's CI (where thetransport round trip already runs against three registry images). Dolos's
test subject is the profile, which is transport-blind by construction; the
two docker-gated dolos-snapshot suites remain as local verification tools,
no longer a CI obligation. AGENTS.md's verification section follows.
ADR-004 is reframed as a pure decision record — the problem (tarball
friction) and the adoption of Stelae: context, decision, rationale,
limitations, alternatives, plus an Adoption section (code layout, CLI and
configuration, development phases). It specifies nothing. The normative
text splits along the boundary the decision drew: the protocol in
txpipe/stelae'sSPEC.md(extended to stand alone: why-OCI, retentionpolicy, the client read order), and the Dolos profile in a new
crates/snapshot/PROFILE.mdbeside the crate that implements it —carrying the ADR's implementation half verbatim, section names preserved
so older citations land on the same headings. Load-bearing code citations
re-pointed. Boundary prose in
crates/snapshot/Cargo.tomldescribes thestructural boundary and the pin discipline (lockstep tags, never a
branch).
The profile's
ocifeature is removed (founder ruling during review):dolos never built without it — the root crate enabled it unconditionally —
so it guarded only combinations no consumer constructs. The stelae crates
keep their own default-off
ocifor third parties;dolos-snapshotturnsthe transport on in its dependency declaration.
backfillstays (it iswhat lets the root
mithrilfeature exclude the mithril-client tree), andthe
snapshot-featuresjob shrinks to the one configuration no workspacejob builds: backfill off.
Byte-compat (done criterion 3, cross-repository half)
One synthetic store set seeded once, then
dolos snapshot digestrun over itby two binaries —
main(e7b4642e, in-workspace crates) and this branch(git-pinned
v0.1.0): stdout byte-identical, one inscription digest. Thegoldens were never re-pinned in any PR of the chain.
