Summary

PR group: Action, render, admin — S2 remainder and dev-surface polish.

  • Don't let cache invalidation fail a committed write
  • Make contract test chore(deps): bump solid-js from 2.0.0-beta.4 to 2.0.0-experimental.16 #2 assert the thing it's named for
  • Fix the erased action view and the fake client codes
  • Stop route-data rethrowing anything with a string code
  • Dev panels: wire what's dark, harden what's wrong
    • live panel's sql was permanently '' → now compiled via query's describeSql, null when no sample is given
    • live panel's "no sync node" note fired even with a running node and zero subscribers → now distinguished from a genuinely unwired source
    • /_x DB panel's write guard false-positived on a write word inside a string literal, and only stripped -- comments → sanitizes literals and both comment forms first
    • ToolRegistry's field used private instead of a real # private field
    • DevPanel.question was an English literal beside titleKey, and titleKey was never rendered → both now go through t()

Test plan

  • bun run verify — 13/17 (4 honest skips: eval, drift, contract-diff, budgets)
  • bun test packages/admin packages/cli packages/mcp packages/query packages/i18n — all green
  • bun run typecheck (root, tsc -b) — clean

sebyx07 and others added 5 commits August 14, 2026 08:20
- `bustAfterCommit` (cache-gate.ts) is now this package's only caller of
  `invalidateTags`: a fan-out that refuses outright (X_CACHE_TAG_UNKNOWN, a
  malformed `invalidates` entry) becomes one `action.invalidate.failed` line
  and the entries expire by TTL, instead of turning a durable write into a
  failed action the caller then retries
- an idempotent replay skips the bust entirely — no handler ran, and the first
  call already busted those tags; re-purging the CDN and re-queueing ISR per
  retry was work for a write nobody made
- 6 tests, each proven red across 5 mutations; CHANGELOG, action README +
  CLAUDE.md and the caching wiki updated

Co-Authored-By: Claude <noreply@anthropic.com>
- `.contract()`'s "policy denies an anonymous actor" sent `{}` and accepted any
  UltimateError, so every action with a required field failed `input:` before
  `guard()` ran and the assertion passed on X_INPUT_INVALID — an `allow()` policy
  passed it too
- new `sample-input.ts` synthesizes an input the schema accepts from its own IR
  (required keys only, formats, nullable -> null); `expectDenied` accepts only an
  ActionDeniedError, the class not X_FORBIDDEN because `can()` answers a null
  actor with X_UNAUTHENTICATED
- anything thrown before the policy is X_CONTRACT_DRIFT naming the new `input:`
  option as the fix; a non-UltimateError keeps its own stack
- new contract-test.contract.test.ts + sample-input.test.ts — 11 mutations red

…ng codes

- AnyAction declares job(): the registry's own view could reach every
  projection but the queue, though facadeFor has bound the method all along.
  client() stays off it and type-pins.ts now says why as a build error:
  ClientMethod is a function type, so its input is contravariant.
- problem+json failures come back as RemoteActionError: the server's code
  verbatim, marked meta.origin: 'remote', linked to the docs the server sent
  or to the error index — never a synthesized page for a code no build here
  registered. A body naming no X_ code is X_RPC_FAILED, which is what it means.

Co-Authored-By: Claude <noreply@anthropic.com>
- `isUltimateError` replaces the `code`-is-a-string duck-type: an ENOENT
  from a loader is wrapped as X_ROUTE_LOAD_FAILED, naming the route to fix,
  while a policy denial or a tier-0 X_VALIDATION_FAILED still passes through
- `defineRoute` takes `RouteDefinition<TData> & LoadRequirement<TData>`, so
  data the context cannot supply requires a `load` — the no-load fallback
  narrows to `RouteContext & TData` instead of `as unknown as TData`
- `RouteContext` is an alias, not an interface: only an alias is a `RouteData`
- type-pins.ts pins all three; 2 new tests, both red against the old check

Co-Authored-By: Claude <noreply@anthropic.com>
- live panel's sql was permanently '' (QueryDescriptor carries no SQL); now
  compiled through query's describeSql via a new sqlSamples option, null
  when no sample is given rather than an invented empty string
- live panel's "no sync node" note fired even when a running node just had
  zero subscribers; distinguished from a genuinely unwired source
- /_x DB panel's write guard false-positived on a write word inside a
  string literal (where kind = 'create') and only stripped -- comments,
  never /* */ ones; sanitizes literals and both comment forms first
- ToolRegistry's tools field used `private` instead of a real `#` field
- DevPanel.question was an English literal beside titleKey, and titleKey
  itself was declared but never rendered; both now go through t() as
  questionKey/titleKey following dev.panel.<key>.title/.question

Review Change Stack

Warning

Review limit reached

You’ve reached a temporary PR review limit under our Fair Usage Limits Policy.

Your recent review volume is higher than typical usage, so adaptive limits are currently applied.

Next review available in: 35 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

📝 Walkthrough

Walkthrough

The pull request updates action contracts, remote RPC errors, post-commit cache invalidation, route loader typing, developer dashboard diagnostics, localization, and runtime-private tool storage. It adds tests and documentation for the updated behavior.

Changes

Runtime contracts and diagnostics

Layer / File(s) Summary
Action contracts and schema-derived inputs
packages/action/src/action.ts, packages/action/src/sample-input.ts, packages/action/src/contract-test.ts, packages/action/src/type-pins.ts, packages/action/src/*.test.ts
Actions expose erased job handles. Contract tests generate or accept valid inputs and require ActionDeniedError for denial assertions.
Remote RPC error preservation
packages/action/src/client.ts, packages/action/src/errors.ts, packages/action/src/index.ts, packages/action/src/client.test.ts, wiki/Error-Codes.md
Problem responses require framework-formatted codes. Valid responses create RemoteActionError instances with preserved metadata and validated documentation links.
Post-commit cache invalidation
packages/action/src/cache-gate.ts, packages/action/src/invoke.ts, packages/action/src/*cache*.test.ts, wiki/Caching-And-Invalidation.md
Cache invalidation runs after committed actions. Failures are logged and do not fail the action. Replays skip invalidation.
Route data and loader contracts
packages/render/src/route.ts, packages/render/src/route-data.ts, packages/render/src/index.ts, packages/render/src/type-pins.ts, packages/render/src/route-data.test.ts
Routes require load when route context cannot provide the requested data. Branded framework errors pass through; other loader errors become X_ROUTE_LOAD_FAILED.
Developer dashboard data and localization
packages/admin/src/dev/*, packages/cli/src/dev-dashboard.ts, packages/i18n/src/catalogs/en.json
Live-query SQL uses optional sample inputs. Read-only SQL checks mask strings and comments. Panels use localized titles and questions. Sync-node availability is tracked separately from subscriber count.
Runtime-private tool storage
packages/mcp/src/registry.ts
ToolRegistry uses a JavaScript private #tools field without changing registry behavior.

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

Merge Risk: 🟠 High · up to cf9b2

The current head improves action completion handling and developer tooling, but a crafted SQL statement can still bypass the developer database panel’s read-only protection, while some action failures may be misreported as input drift and hide the real cause. These concrete data-safety and correctness risks should be fixed before merge.

Inline comments:
In `@packages/action/src/cache-gate.test.ts`:
- Around line 1-4: Add a 1–4 line header comment before the imports in the
cache-gate test file stating that it verifies post-commit invalidation, because
cache failure must not reverse an action result.

In `@packages/action/src/client.ts`:
- Line 159: Update the fallback cause construction in the client error handling
to use the localization function t() rather than the hardcoded “failed with”
message. Add the corresponding catalog key and format it with the operation name
and response status, while preserving the existing body cause/detail precedence.
- Around line 161-164: Update the RemoteActionError construction to validate
both docs and type as HTTP(S) URLs before selecting a value, preferring the
first resolvable URL from body['docs'] then body['type']; ensure an unsafe
non-empty docs value cannot suppress a valid type, and add coverage for
javascript docs with an HTTPS type.

In `@packages/action/src/contract-test.contract.test.ts`:
- Around line 34-38: Update the missing-contract guard in the at function to
throw ContractDriftError imported from ./errors, preserving the index context
and the error’s existing stable code and executable fix guidance. Leave the
fixture throws in expectDenied and the other test path unchanged.

In `@packages/action/src/contract-test.ts`:
- Around line 118-129: Update the catch branch in contractTestsFor to convert
only UltimateError codes produced before policy evaluation into
ContractDriftError; rethrow post-policy UltimateErrors, including handler and
output errors, unchanged so their original code and fix remain intact. Add a
contract test covering policy allow() with a handler that throws an
UltimateError and assert the thrown code is preserved.

In `@packages/admin/src/dev/panel-db.ts`:
- Around line 33-37: Update sanitize() and the assertReadOnly() guard so comment
markers inside quoted identifiers are not interpreted as comments; prefer
database-enforced read-only execution, or use a complete lexer supporting all
quoted SQL forms. Add a regression test covering SELECT 1 AS "--"; DELETE FROM
members while preserving existing read-only guard behavior.

In `@packages/admin/src/dev/panel-live.ts`:
- Around line 35-38: Update the subscriber lookup try/catch around
sources.subscribers() so wired is set to false only when the error matches the
stable unavailable-source error produced by unwired(); rethrow authorization,
network, implementation, and all other errors to preserve actionable
diagnostics.

In `@packages/admin/src/dev/panel.ts`:
- Around line 11-15: Update the documentation above the questionKey property to
describe the sibling-key convention: questionKey should use the same base as
titleKey with the final title segment replaced by question, such as
dev.panel.jobs.title and dev.panel.jobs.question, rather than appending
.question to titleKey.

In `@packages/render/README.md`:
- Around line 41-55: Update the load-contract prose around defineRoute so it
begins with “As of 2026-07,” removes the “Axiom 3 again” meta-framing, and
directly states that meta may only access context-provided data when load is
omitted; richer data requires a loader. Preserve the existing compile-time and
error-propagation details.

In `@packages/render/src/route-data.test.ts`:
- Line 121: Replace the bare Error throws in the test loaders with named
fixtures: keep the ENOENT fixture unbranded, and make the tier-0 fixture include
code, cause, and executable fix properties. Update the routeDataFor() assertion
to verify that the tier-0 path rethrows the exact same error object.

In `@scripts/reference-app-gate.ts`:
- Around line 49-51: Update the contract pin text in the gate output to replace
the stray backtick in “publishPost`s” with an apostrophe and insert “that”
before “loader makes,” preserving the surrounding wording.

In `@wiki/Caching-And-Invalidation.md`:
- Around line 88-89: The caching documentation describes an outbox-based
invalidation contract that does not match the direct post-handler execution in
invalidateTags() from cache-gate.ts. Update the documentation to describe the
direct attempt after handle resolves, including its failure and idempotent
replay behavior, and align the duplicated descriptions so they state this
contract only once.

In `@wiki/Error-Codes.md`:
- Line 188: Update the X_RPC_FAILED description in the error-code table to state
that the response body names no X_SCREAMING_SNAKE framework code, replacing the
narrower “no X_ code” wording.

Review follow-ups on #72.

- `/_x` DB panel: `select 1 as "--"; delete from members` read as a plain
  SELECT. Sequential blanking passes cannot be ordered correctly — each
  opaque form contains another's opener — so `sanitize()` is now ONE
  left-to-right alternation over `'…'`, `"…"`, `$tag$…$tag$` and both
  comment forms. An unterminated quote leaves the rest visible: closed.
- `/_x/live`: a bare `catch` retold an authz refusal or a dropped NATS
  connection as `dev.live.no-sync-node`. Now `DevSourceUnavailableError`
  only; everything else keeps its code and fix through `panelPayload`.
- Contract test: only `X_INPUT_INVALID` becomes `X_CONTRACT_DRIFT`. An
  `X_OUTPUT_INVALID` was reported as input drift "before its policy
  decided", which hid the `allow()` the assertion exists to catch.
- Typed client: `docs ?? type` selected on presence, so a `javascript:`
  `docs` buried a valid HTTPS `type`. Both travel ordered; `remoteDocs`
  takes the first absolute http(s) URL.
- Docs: wiki stated an outbox contract `bustAfterCommit` never had;
  render README dated and de-meta-framed; gate pin text unmangled.
- Tests: named route-data fixtures with identity assertions, new
  panel-live suite, SQL-bypass regressions — 8 mutations verified red.
