Report superseded Goldsky subgraph deploys

[thedavidmeister]

Closes #3.

Adds crates/metaboard-subgraph-report: enumerate the subgraphs deployed on
Goldsky and classify each deployed version as retained or as a reaping
candidate.

GOLDSKY_TOKEN=… nix run .#metaboard-subgraph-report
GOLDSKY_TOKEN=… nix run .#metaboard-subgraph-report -- --format json
GOLDSKY_TOKEN=… nix run .#metaboard-subgraph-report -- --format candidates

This is the first rust in the repo, so it also brings the workspace, the
rs-static / rs-test lanes, and a nix run-able package so a scheduled
workflow needs no dev shell.

Two things in #3 that the API does not support, and what replaces them

#3's premise about usage metrics is false. It asks for per-deployment
queries / bandwidth / last-query timestamp, on the stated basis that "Goldsky
exposes per-subgraph metrics via its API". It does not. The subgraph admin API
— the one Goldsky's own CLI drives — has a listing endpoint, per-version
deployment records, tags, logs, pause/start and webhooks, and no usage or
metrics endpoint of any kind. No listing field carries a query count, a
bandwidth figure or a last-query time. So "nothing queries this" cannot be
established from the API, and this tool never claims it: the JSON report
carries usage_metrics_available: false, and the table and JSON both print the
caveat verbatim.

What it reports instead is supersession, which is exactly the residue #3's
own trigger paragraph describes. subgraph-deploy is idempotent by name and
version, so it skips a version already deployed and never removes the one it
replaced; every old <address>-<commit> slot stays live indefinitely. A
deployed version is a candidate when it is all of:

• not the target of any Goldsky tag on its own name,
• not the newest version for its name,
• not --keep-pinned by the caller, and
• at least --min-age-days old (default 30).

Superseded is a weaker claim than unused, and the report says so where a reader
will see it rather than only in the docs.

#3 also proposes a rain-metadata CLI subcommand. That proposal predates
rainlanguage/rain.metadata#134. Which deploys exist and which are stale is a
deploy-records question, the same class of fact as src/generated/<tag>/, so
it lands here rather than in the library half.

It cannot delete anything

By construction, not by policy. GoldskyClient can issue exactly one request —
the listing GET. No delete, pause or mutate path exists anywhere in the
crate. The output is name/version identifiers plus the reason each was
selected, never a runnable command line or a script; two tests pin that
(the_candidate_list_never_emits_a_runnable_delete_command,
the_table_never_emits_a_runnable_delete_command). Reaping stays a human
running goldsky subgraph delete.

Retention wins every tie

Anything not positively established is retained, with its reason recorded — a
false retention costs a little Goldsky spend, a false candidate risks deleting
a live subgraph. So: unknown age is retained (unknown-age), an undated row
never establishes a newest for its name, a dangling tag is reported but
protects nothing and is itself never a candidate, an alias row carrying its own
timestamp does not displace the real newest, a lone version is newest by
definition, and a --keep pin beats every other reason.

The default --name-prefix is metaboard, matching the current deploy rule's
metaboard-<network>. Older live deploys use other stems, so --name-prefix
is repeatable and --name-prefix "" sweeps everything.

Verification

• cargo test --workspace: 89 passed, 0 failed.
• rainix-rs-static (cargo fmt --check, cargo clippy --all-targets --all-features -D warnings): clean.
• nix build .#metaboard-subgraph-report: builds, and the resulting binary
  runs.
• Adversarial mutation probe, 24 mutants, each breaking one decision in the
  classifier, the listing reduction or the rendering: 24/24 killed, 0
  survived, 0 no-run, 0 harness errors, plus 3 hand-run mutants for the
  camelCase aliases, also all killed. Includes M21 ("the report claims usage
  metrics are available") and M23 ("the candidate reason code claims measured
  disuse"), so the two claims this PR is careful not to make are pinned by tests
  rather than by prose. The probe's inputs were a one-off and are not committed;
  the full table is in the QA block below.

What was NOT exercised live

The authenticated 200 listing path has never run against real Goldsky. No
CI_GOLDSKY_TOKEN was available while building this. What was reproduced end
to end against api.goldsky.com is the failure half: a bogus token returns
HTTP 401: Make sure to run 'goldsky login' before running any commands requiring authorization, surfaced with a non-zero exit; and an absent token is
refused before any request is made. Everything about the success path — the
response shape, the deployment records, how tag rows actually come back — is
modelled from Goldsky's documented API and covered by httpmock fixtures, not
confirmed against a live 200. First real run should be --format table and
should be read, not trusted. Nothing can be deleted by getting this wrong,
which is why the client has no delete path at all.

Pagination is unknown. list_subgraphs reads only data out of a single
GET; nothing here pages. If the listing does page, a tag row on page 2 stops
protecting its target on page 1 — the same false-candidate direction. This is
not verifiable without a token, and inventing pagination against an API whose
success body has never been seen would be a guess of exactly the class this PR
is trying not to make, so it is stated here rather than coded.

The field spellings are covered, not confirmed. The listing fields are read
under both snake_case and camelCase (#[serde(alias = ..)]), so neither
spelling can be the wrong one; but no live 200 has shown which Goldsky actually
sends, nor that these are the only fields whose spelling matters.

Applied after review

• fix: accept camelCase spellings on the Goldsky listing fields —
  graphql_endpoint, target_version and created_at were snake_case on no
  live evidence, while the one body captured verbatim from api.goldsky.com
  (the 401) is camelCase. A missed targetVersion would make every tag read as
  dangling, and a dangling tag protects nothing, so a live tag's target would
  have been offered up as a reaping candidate. Both spellings are now accepted,
  with a test per field plus a fully-camelCase listing over httpmock.
• chore: drop check.sh — the other half of the one-off probe, dropped
  alongside mutants.toml for the same reason. Nothing invoked it.
• chore: drop dangling_tag_count — a public function whose only caller was its
  own test, whose doc claimed dangling tags were "surfaced" through it when
  neither renderer touches it. The table already prints [no target] (dangling)
  straight off report.tags.

Conflicts with #4

Both PRs edit the same CLAUDE.md paragraph about what does and does not live in
this repo, and both are correct about their own half: #4 moves the subgraph
here, this PR adds the one rust crate that belongs here. Whichever lands
second should merge both clauses — the metadata rust crates stay in
rain.metadata, the subgraph is here, and the crate here reports on Goldsky
deploys and is not metadata logic — rather than take either side wholesale.

The REUSE.toml re-indent in this diff is the repo's own taplo pre-commit
hook reformatting a block that predates it; only the three Cargo.lock /
Cargo.toml / crates/**/ entries are mine.

QA

• Discriminating tests: 89 tests in classify::tests, goldsky::tests,
  report::tests. "Fails on base" carries no signal here — the crate does not
  exist on main @ 4465374, so every one of them fails on base for the trivial
  reason. The discrimination evidence is the mutation table below: each test
  named there was run against a specific broken line and observed to fail, and
  against the correct line and observed to pass. The two that pin the no-delete
  property are report::tests::the_candidate_list_never_emits_a_runnable_delete_command
  and report::tests::the_table_never_emits_a_runnable_delete_command.
• Mutations applied: 24 mutants over the classifier, the listing reduction and
  the rendering, run with mutation-probe against cargo test --workspace.
  Baseline green at 85 passed. Result: 24 killed, 0 survived, 0 no-run, 0
  harness errors. Plus 3 further mutants run by hand for the camelCase
  aliases added after review — one alias deleted at a time, cargo test
  re-run each time: 3 killed, 0 survived (the last three rows). Killing
  test shown is the first named; (+n more) is how many others also failed.
  The probe was a one-off: neither its mutants.toml nor the check.sh
  wrapper it drove is committed, because nothing in the org runs
  mutation-probe in CI and a committed config reads as standing coverage that
  no pipeline executes. This table is the evidence, and it is the only place
  that evidence lives.

• Oracle: expected values are hand-written from the stated rule, never captured
  from the implementation's own output. The Goldsky response fixtures are
  hand-written JSON bodies served by httpmock, shaped from the documented
  admin-API listing rather than recorded from a live call. Classification
  expectations assert the retention rule directly and by name — a pinned
  version is retained however old and superseded, a tag only protects its own
  name, an undated row establishes no newest. The age arithmetic is checked at
  literal boundary values worked out by hand (NOW - DAY - 1 → 1 day, NOW - 2*DAY + 1 → 1 day, exactly min_age_days old is a candidate, one
  millisecond younger is not). No test compares the code to itself.
• Category check: Tooling to identify and reap unused deployed subgraphs on Goldsky #3 asks for (A) enumeration of every metaboard-named
  subgraph deployed on Goldsky across all networks, (B) per-deployment usage
  stats, (C) a reaping path suitable for goldsky subgraph delete. A is
  covered — the listing GET plus a repeatable --name-prefix, with
  --name-prefix "" sweeping every name; each row carries its network. B is
  not covered and is not coverable — the API exposes no usage endpoint or
  field, so rather than approximate it this PR reports supersession and states
  the absence in its own output (usage_metrics_available: false, pinned by
  mutant M21). C is covered as a report, deliberately not as a script —
  --format candidates emits the name/version identifiers a human hands to
  the Goldsky CLI, and no delete path exists in the crate. Tooling to identify and reap unused deployed subgraphs on Goldsky #3's "possible
  shapes" also floats a weekly scheduled GHA; that is not here, and the
  nix run-able package is the hook a later change would use. Closing Tooling to identify and reap unused deployed subgraphs on Goldsky #3 on
  the basis that its substantive ask is answered and its one false premise is
  refuted with evidence rather than quietly dropped — say so if you would
  rather this were Refs #3 with a follow-up for the schedule.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟡 Moderate · up to 198d8

The PR adds a read-only Goldsky deployment report and new Rust build/validation workflows, but the current changes may fail legal validation and weaken CI supply-chain and secret-isolation guarantees because required metadata and workflow pinning/permissions are incomplete. These issues should be fixed or explicitly accepted before merge.

GitHub Actions reusable workflow secrets inherit secrets not explicitly defined workflow_call.secrets permissions caller called workflow

💡 Result:

In GitHub Actions, you can pass secrets to a reusable workflow using the secrets: inherit keyword or by explicitly defining them in the calling job [1][2]. When you use secrets: inherit in the calling workflow, all secrets available to the caller are implicitly passed to the called workflow [1][3]. A key advantage of using inherit is that you can reference these secrets in the reusable workflow even if they are not explicitly defined in the on.workflow_call.secrets section of the reusable workflow's configuration [1][4][2]. If you choose not to use inherit, you must explicitly pass each secret by mapping it in the calling job, and the reusable workflow must define these secrets under the on.workflow_call.secrets section to access them [5][6][7]. Important considerations regarding secret inheritance: 1. Scope: Secrets are only passed to the directly called workflow. In a chain of workflows (A -> B -> C), workflow C only receives secrets from A if they are explicitly passed (or inherited) through each link in the chain [1][2]. 2. Environment Secrets: The on.workflow_call trigger does not support the environment keyword [1]. If a job in your reusable workflow specifies an environment, it will use that environment's secrets rather than the secrets passed from the caller [1][4]. 3. Security: The inherit option is intended for use within the same organization or enterprise [5][3]. Passing secrets to external or third-party reusable workflows via inherit is generally discouraged due to security implications [7].

Both calls use mutable @main references and pass all caller secrets to external workflows. Set explicit least-privilege permissions as required. Keep secrets: inherit until the reusable workflows declare named workflow_call secrets; otherwise CACHIX_AUTH_TOKEN will not be available.

Not actioned, deliberately.

The four workflows already on main — rainix-sol, manual-sol-artifacts, package-release, git-clean — all use rainlanguage/rainix/...@main with secrets: inherit. The two added here match that exactly. Pinning only the two new ones would make this repo internally inconsistent and would not close the exposure the finding describes, since the other four keep the same reference.

It is a real question, but an org-wide one about how rainix is consumed. It wants an issue against the convention, not a divergence introduced by a PR about Goldsky reporting.

[coderabbitai]

@thedavidmeister, understood.

The two new workflows follow the existing repository convention. Pinning only these calls would not resolve the repository-wide risk from the other rainlanguage/rainix/...@main calls with secrets: inherit.

The security concern remains valid, but it is outside this PR’s scope. Would you like me to open a GitHub issue for an organization-wide review of the Rainix reusable-workflow reference and secret-passing convention?

✏️ Learnings added

Learning: In `rainlanguage/rain.metadata.deploy`, the existing GitHub Actions workflows `rainix-sol`, `manual-sol-artifacts`, `package-release`, and `git-clean` call reusable workflows from `rainlanguage/rainix` at `main` with `secrets: inherit`. New workflow calls should follow this repository convention unless an organization-wide policy change is made. Pinning reusable workflows and reducing inherited secrets requires an organization-wide follow-up rather than an isolated change in a feature PR.

Review disposition, so the reasoning is on the record rather than only in the resolved threads.

Actioned

• REUSE.toml — check.sh and mutants.toml had no SPDX header and matched no glob, so reuse lint failed. Real, and it was the rainix-sol / legal failure. Fixed in f03008d by adding both to the annotation list, matching how flake.nix and foundry.toml are covered here rather than growing headers.
• README.md MD040 — fenced block had no language. Fixed in 389cb20.

Also in f03008d, not flagged by review: .coderabbitai.yaml had a blank line yamlfmt strips. It predates this branch and surfaces now only because this branch is what adds the rs-static lane, which runs pre-commit run --all-files; the sol lanes never ran yamlfmt over it.

Not actioned, with reasons

• Pin the reusable workflow calls to SHAs / add least-privilege permissions. The four workflows already on main — rainix-sol, manual-sol-artifacts, package-release, git-clean — all use rainlanguage/rainix/...@main with secrets: inherit. The two added here match that exactly. Pinning only the two new ones would make this repo internally inconsistent and would not close the exposure the finding describes, since the other four keep the same reference. It is a real org-wide question about how rainix is consumed, and it wants an issue against the convention, not a divergence smuggled into a PR about Goldsky reporting.
• resolver = "3" to match edition 2024. rain.metadata's workspace — the sibling half of this split — is on resolver = "2". Nothing in either workspace declares rust-version, so resolver 3's only behavioural change (incompatible-rust-versions = "fallback") has nothing to act on and the switch is a no-op that diverges from the sibling repo. Keeping "2".
• reqwest 0.13.4 / thiserror 2.0.20. rain.metadata pins reqwest = "0.11.17" and thiserror = "1.0.56". This crate's 0.11.22 / 1.0.56 are the same major lines on purpose. Moving a new crate ahead of the org's other rust would be a dependency-policy decision, and belongs in one change across the repos rather than here.

Finding text was read as data, and each was checked against the current tree before being actioned or skipped.
