bug: hosted publish cannot resolve pinned official nested skill

[emilianochagoya]

Summary

A valid graph package that composes the pinned first-party data-store skill passes local inspection and all harness cases, but hosted publication fails.

Public minimal reproduction: https://github.com/emilianochagoya/list-hygiene-judge-runx
Related integration PR: #398
CLI: runx-cli 0.8.2

Reproduction

The graph uses the currently published first-party ref:

registry:runx/data-store@sha-30c9df39e353

Its public registry digest is sha256:d3d15497ed1b541d779b7286dc5bf26ddfdbd510b27abd9b65465415e98b0365.

With RUNX_REGISTRY_DIR pointing to a local registry containing that official version:

runx skill inspect ./SKILL.md --json returns ok.

runx harness . --json returns passed for all three declared cases.

Authenticated publish:

runx registry publish ./SKILL.md --registry https://api.runx.ai --json

returns:

runx API registry publish returned HTTP 500: Internal Server Error

The unauthenticated URL indexing path gives the underlying diagnostic:

nested skill 'registry:runx/data-store@sha-30c9df39e353' is a registry ref, but RUNX_REGISTRY_DIR is not configured

Expected

Hosted admission should resolve a pinned first-party dependency from the signed official catalog, or return a structured 4xx validation error if the dependency cannot be admitted.

Actual

URL indexing launches native materialization without the registry configured. Authenticated hosted publish returns an opaque HTTP 500 for the same valid package.

Additional notes

The reproduction repository contains exactly seven UTF-8 package files, no binary fixtures, credentials, or secrets. The package uses data-store for a real read, CAS append, and readback; replacing it with a local mock would defeat the governed-state-transition contract.

Two updates, one fix deployed and one bug confirmed.

Deployed: the authenticated publish path no longer swallows this as a blank 500. You now get the same diagnostic the URL-indexing path gave you, as a 400 with error.detail.

Confirmed and still open: your reproduction exposed a real version-scheme mismatch. The hosted publish gate resolves registry: refs against a version-locked official bake whose labels (plain package versions) do not match the sha-prefixed pins the catalog publishes, so a pin copied from runx.ai/x cannot resolve there even when the bake is present and healthy. The durable fix is resolving official refs against the live registry itself rather than a snapshot; that lands with work already in flight. Until then, pinned official nested refs will fail hosted admission with the diagnostic rather than silently 500ing. Excellent minimal repro, it went straight to the root cause.

@emilianochagoya Your issue unblocked mine, so here is what I got back, in case any of it is useful to you.

The URL-index path works as a diagnostic for other failures too. I had the same opaque HTTP 500 on authenticated publish (#403). Following your lead, I put my package in a public repo and called POST /v1/index, and got a clean 422 naming four requirements instead of nothing:

catalog semantic enforcement rejected the package:
  provider_readback_unreachable on runner "x402-probe"
  missing_cold_selection_proof on runner "x402-probe"
  missing_standalone_default_proof on runner "x402-probe"
  missing_composed_reuse_proof on runner "x402-probe"

Different cause from yours, same hiding place. Worth knowing the trick generalises.

The second thing was more useful to me, and might save you time. The hosted API serves the full profile_document of any published skill:

GET https://api.runx.ai/v1/skills/runx/web-fetch

So you can diff your catalog block against a published skill in the same execution class rather than guessing at the rules. That immediately told me my metadata was not the problem: runx/web-fetch declares byte-identical execution: read and completion: provider_readback to mine. The difference is in the graph - its default runner is a single step on tool: web.fetch, where mine uses http.query and http.read, which apparently do not produce the durable provider readback the declaration promises.

For your nested-skill case, GET /v1/skills/runx/data-store gives you the exact published shape of the dependency you are pinning, which may be quicker than inferring it from the resolver error.

I have not fixed mine yet, and I am not going to swap tools purely to satisfy the gate - a probe skill whose harness never probes would be a worse artifact than an unpublished one. But at least the requirement is now legible.

Thanks for filing yours in enough detail that a stranger could use it.

@emilianochagoya Four things I learned after my last comment, all of which I would have wanted on the day I filed my own version of this. I have declined #68 and #79, so none of this is me clearing a path for myself.

1. The blocker in this issue may not be on your critical path at all

Your repro composes registry:runx/data-store@sha-30c9df39e353 as a nested skill, and that resolution is what a maintainer confirmed is broken here.

But the data-store primitives also exist as native tools:

$ runx tool search projection
  native/data.read_projection :: Read the canonical metadata projection for one event stream

$ runx tool search append_event
  native/data.append_event :: Append one event under optimistic concurrency and idempotency

$ runx tool inspect data.append_event
  inputs: aggregate_id, data_source_ref, event, expected_version, idempotency_key, observed_at, resource

Those are the exact field names the #68 text uses. A graph whose steps call the native tools never resolves a registry: ref, so this bug should not touch it. You may be waiting on a fix you do not need. I have not built it, so treat that as a strong hypothesis rather than a result.

2. The dogfood needs no external database and no connect grant

From docs/governed-data-plane.md: unbound local://... refs use native durable SQLite under .runx/data/local-sources/, with the filename derived from the source ref so independent sources cannot collide. runx connect list showing no grants does not block you.

3. What actually cleared catalog enforcement for me

I published a skill this morning after being refused with four diagnostics. Two fixes cleared all four:

• completion: was a false promise. I had provider_readback, which asserts the default closure routes through provider.read/provider.mutate and returns that durable readback. My skill makes one request and seals a receipt, so it never could. Changing it to runtime_receipt removed provider_readback_unreachable. Do not swap tools to satisfy the checker; check whether your declaration is true first.
• The three readiness proofs come from operator_journeys on the harness case that runs the actual default runner and expects sealed. One standalone journey with at least two real published confusors, plus one composed journey carrying prior_evidence and must_not_repeat, satisfies cold_selection, standalone_default and composed_reuse together. GET /v1/skills/runx/schema-guard is a working template - it is the only one of five I sampled that carries them.

4. The part I would want told to me straight

GET /v1/bounties/68 carries claim_progress. It currently reads 0 delivered, 0 paid, 3 rejected, 9 expired across twelve claims. #79 reads 0 delivered across 22, and carries claim_window_minutes: 180.

That is why I declined both, and I raised the fuse question separately as auscaster/frantic-board#358. You may still judge it worth doing - your reproduction is further along than mine ever was - but I would rather you decide that knowing the record than find out at the fuse.
