runtime: publish node known environments into runtime provisioning catalog - #1615
Register the runtime definitions a registered node already reports, so an enabled provisioning cohort can install them without manual catalog inserts.
For each validated environments.known entry, execute one INSERT ... ON CONFLICT (environment_ref) DO NOTHING inside the existing inventory transaction. Existing rows, compatibility edges, and operator retirement are untouched. Missing, unavailable, and malformed observations cannot erase or partially publish the catalog.
No advisory locks, catalog-admission quota, certification merging, JSON batching, or deferred-entry accounting. The existing desired-state recipe limit remains unchanged; operators retire old entries if the active catalog outgrows it.
The legacy upgrade reader skips profiles without kernel/snapshot metadata and recognizes known runtime aliases, so runtime-neutral rows cannot break unrelated activations and fc matches firecracker. Its query stays in the owning catalog store. Installation remains separate from execution permission; no cohort or upgrade flag is enabled.
Final head b2475c902 passed 61 scoped tests on RemoteBox (catalog 4, publication 13, desired state 17, runtime upgrades 27), all-target scoped Clippy with warnings denied, isolated library checks, formatting, and secrets checks. Runtime-alias assertions added to existing attribution tests fail without the fix and pass with it. Architecture validation has zero required findings and two advisories: the pre-existing template-manager declaration and the intentional API-to-catalog-store ownership edge.
Regression coverage: published_known_environment_reaches_the_runtime_recipe_catalog proves registration reaches provisioning; registration_is_idempotent_and_preserves_existing_metadata_and_retirement covers concurrent registration and existing-row preservation. Removed tests covered the discarded admission quota and certification merging, neither of which belongs to this insert-only operation; the existing oversized-recipe test remains passing.
Fresh real-service proof passed at this head: run space-runtime-fixture-0647200a041f, inner exit 0, no cleanup failures. Changing only the API binary on the same worker/database changed the actual Firecracker 1.17 binding CLI from exit 1 (missing artifact directory) to exit 0 after automatic installation. Firecracker/jailer/kernel hashes match their pins; non-API binaries are unchanged. Run-owned containers/network are gone and cgroup limits are unchanged. This is installation and binding proof, not local guest-VM boot.
Pull CI and Kind Direct CI passed on final head b2475c902. Direct-substrate typed smoke passed 51 ECW and 31 native scenarios with zero warnings, failures, inconclusive results, infrastructure errors, or accepted known failures. Earlier five-query batching results are historical and do not describe this implementation.
The final CodeRabbit review's two outside-diff recommendations, admission quotas and batching, are deliberately deferred to keep registration simple. The existing 32-entry recipe guard remains fail-closed; operators retire old entries if that limit is exceeded. Per-definition inserts retain linear report cost but hold no global advisory lock.
Severity and risk
Severity: P2. Runtime definitions already reported by nodes were not entering the provisioning catalog, leaving installation recipes empty.
Risk: node reports can add catalog rows but never revise existing certifications or retirement. The existing oversized-recipe guard remains fail-closed. Nullable runtime-neutral metadata also requires the optional-components migration and null-safe legacy readers before publication.
For a cluster with runtime upgrades enabled: disable SPACE_RUNTIME_UPGRADE_AT_ACTIVATION_ENABLED across old API/controller replicas, verify they have exited, deploy null-safe readers everywhere, then deploy the publisher before re-enabling upgrades. Disable upgrades before rolling readers back; stopping publication does not remove durable nullable rows. No live rollout is part of this PR.
AI assistance: Perplexity drafted implementation, tests, documentation, and validation evidence; the admission-control and batching machinery was subsequently removed to keep this change insert-only.
Why: Bound catalog publication and validate snapshot restore behavior before merging. An oversized catalog suppresses new installation recipes.
Commit: b2475c90289b.
Walkthrough
The catalog store now registers known environments without changing existing rows when a reference conflicts. It lists unretired legacy upgrade candidates only when kernel and state-format metadata is present. The observation API validates environment data before inventory publication, then registers known environments. The API retrieves upgrade candidates through the catalog store. Runtime attribution accepts aliases for known runtime kinds. Tests and documentation cover these behaviors and rollout requirements.

Merge Risk: High · up to b2475
Bound catalog publication and validate snapshot restore behavior before merging. An oversized catalog suppresses new installation recipes.
Security architecture risk: Moderate · up to b2475
A compromised registered node can publish enough distinct valid environments to stop new provisioning assignments across an enabled cohort until operators retire entries. Existing installations and execution-permission controls remain independent. Insert-only registration and documented rollout sequencing otherwise contain the reviewed state-transition risks.
Retained concerns
Medium · security · inferred: The new publication path lets one compromised authenticated node add distinct valid environments without an admission bound. Once the shared catalog contains more than 32 unretired entries, every admitted worker and builder receives no new provisioning recipe. Repeated reports with new references can sustain this condition until operator retirement; disabling publication does not remove the durable rows. This is a new cross-node availability path, not an execution-permission bypass.
Security review details
Security Blast Radius
inferred — The supported attack prerequisite is control of an authenticated registered node's publication, not an unauthenticated or ordinary tenant request. Catalog saturation affects new provisioning assignments for all admitted workers and builders sharing that catalog. Actual cohort size and broader deployment sharing were not established.
Security Findings and Attack Paths
inferred — A compromised publisher can submit internally valid definitions with distinct references, causing successful insert-only registrations until the active catalog exceeds 32 entries. The consumer then repeatedly omits the whole recipe. Definition and graph validation do not enforce cumulative capacity, and operator retirement is the documented recovery mechanism.
Trust Boundaries and Controls
observed — Provisioning and execution permission use separate response fields. Catalog read failures or oversize omit only the recipe, and node control applies execution policy before installation. The saturation path therefore does not itself remove an execution block or grant permission.
observed — Alias attribution feeds the existing feature-gated policy planner rather than independently granting upgrade authority. Cold-boot upgrades additionally require a source and certified upgrade edge in the node's compiled catalog.
Resilience and Maintainability Implications
observed — An absent recipe preserves existing installations and pending installation intent. The normal producer reports its compiled catalog, currently five entries on x86_64 and none on aarch64. These controls reduce ordinary exposure but do not constrain fabricated publications from a compromised node.
Hardening Proposals
proposed — Separate observed environments from admitted provisioning entries, or enforce a concurrency-safe admission budget aligned with the consumer limit. Preserve existing metadata and retirement while preventing one publisher from exhausting shared provisioning capacity.

RemoteBox proof: exact missing-FC-1.17 binding failure, then recovery
Ran a matched before/after on Linux RemoteBox against real binaries. This is a
Docker-isolated, direct-service test, not Kind. It exercises the real
node-manager execution-binding resolver, not just inventory reporting.
Before
Started fresh PostgreSQL/Redis, node-manager, runtime-manager, node-ctl, and the
unfixed internal-api. The managed runtime/artifact roots were empty. Normal
node-ctl publication was accepted, but two consecutive desired-state polls
returned an empty runtime recipe.
code: 'The system is not in a state required for the operation's execution', message: "execution binding unavailable: inspect execution source /space/vendor/artifacts/firecracker/v1.17.0--a2280f9533dd"
The named directory did not exist. This reproduces the concrete binding failure
in the reported sandbox-create incident.
Change only the API binary
Stopped the unfixed internal-api and started the fixed internal-api against the
same database and Redis. The worker and the node-manager, runtime-manager, and
node-ctl processes stayed alive with unchanged PIDs. There was no runtime install
command, direct catalog insertion, second fixture seed, or artifact-directory
copy during the transition.
Normal node-ctl publication populated the recipe, including the target
environment reference. Normal reconciliation then downloaded and published the
runtime/kernel bytes through node-manager.
After
Reran the identical real node-manager CLI command. Exit code: 0, empty stderr.
Its JSON response included:
The directory that previously caused the error now existed. The target
environment was in usable inventory; the installed files were nonempty and
their SHA-256 digests matched the catalog pins:
Unfixed API binary SHA-256: 0734399b1c8842b60a903a33ba4933bd97680c5bd4fc001ebd453294e0a781b4.
Fixed API binary SHA-256: 0e45494d0e49e0093a10881a86e8573b3eb7961ed0ebb2f27e7ef028d0e06bf0.
Reused real binaries built from baseline 651df81708e2b467afc6c9143bfb392c5de0a137
with/without the publisher. The fixed binary's relevant production source
blobs and lockfile match this PR head; the optional-metadata migrations are
present in both arms.
Local receipts and service logs are retained at /home/dev/runtime-provisioning-local-evidence/space-runtime-fixture-07eda9b39575/.
The disposable containers/network were removed, cleanup reported no failures,
and before/after host-limit snapshots were equal.
The extra validation harness stays outside this PR; no production-code changes
were needed for this proof.
This demonstrates that the fix removes the exact missing-FC-1.17
execution-binding failure, not merely that inventory lists 1.17. It does not
replay HTTP sandbox creation or boot a guest, and does not claim the entire
sandbox-create path or production is healthy. A separate firmware artifact has
no enabled source; this is target-specific proof, not full catalog convergence.

Included review availability: This review used your included allowance. Your plan provides up to 12 included reviews per hour; 11 remain after this review.
The follow-up fixes the active review findings and closes the two obsolete smoke-fixture threads whose code was already removed from this PR.
Unchanged-report contention: insert-if-absent and conditional certification updates are separate statements. Existing unchanged reports take no catalog tuple-update or admission lock.
Durable admission bound: new references serialize against the persisted unretired catalog count, bounded by MAX_RECIPE_ENVIRONMENTS. Repeated and concurrent reports cannot overflow the recipe. At capacity, inventory still commits, existing certifications can narrow, and new references are deferred until operator retirement frees space.
Validation precision: malformed-report tests assert gRPC InvalidArgument, not merely any error.
Conditional rollout wording: an enabled cohort still needs a successful known-environment publication; an empty catalog does not seed itself.
Nullable metadata compatibility: the legacy activation reader now uses the catalog store and omits profiles lacking its required legacy attribution metadata. The regression includes kernel-less, snapshot-less, and metadata-free profiles alongside supported entries. Mixed-version deployment and rollback ordering are documented.
Registered-node trust is unchanged: this cap prevents recipe suppression through unbounded accumulation, not independent release approval or protection of future free slots against a compromised registered node.

Failure of the persisted-capacity regression when admission is unbounded.
Nullable metadata decode failure (UnexpectedNullError) without the legacy-reader predicate.
The earlier matched real-service before/after proof predates these production changes. It was not rerun for this follow-up, and this validation does not claim guest-boot or live-rollout coverage.
The PR still depends on #1614. Follow the documented reader-first rollout with runtime upgrades disabled across old replicas before nullable rows can be published.

crates/l40_api/internal/api/server/src/execution_observation.rs:136: auto-registration can push the catalog past the recipe cap. When that happens, recipes stop for the whole cohort, and the only sign is a log line. register_known inserts every new environments.known entry and never removes one, so the unretired catalog only grows unless an operator retires rows. When list_unretired returns more than MAX_RECIPE_ENVIRONMENTS (32), runtime_desired_state.rs:112 omits the recipe for every admitted node. Node-ctl treats an absent recipe as "assign nothing" (runtime_provisioning.rs:151). Nothing is uninstalled, but nothing new installs either. That includes a freshly certified environment shipped as a 0-day response, which is exactly when the recipe matters. Today the only signal is the tracing::error! at line 113, and before this PR every row came from a deliberate insert.
This PR is a good place to make the overflow observable: a gauge for the unretired catalog size against the limit, or a counter for omitted recipes, so it can be alerted on before it bites. Rejecting registrations at the cap would protect the cap. But it would silently drop newly reported environments, which is the 0-day path again, so I wouldn't go that way.
Verified against b2475c90289b9a6ae904cb1c57f9b4a39d1bbbcb, diffed against its base fix/runtime-environment-optional-components (this PR is stacked on PR #1614, which needs to land first). I read the registration path through EnvironmentObservation::from_inventory, which decodes the whole report before any write. I also read the insert-only SQL, the null-skipping legacy reader and the same_runtime alias match. To confirm the consequence above, I followed the overflow path through runtime_desired_state.rs and node-ctl's absent-recipe handling. codex review reported nothing further. I didn't run the test suite or the real-service fixture. I also checked the diff and PR text for private information and found nothing.

Summary
Register the runtime definitions a registered node already reports, so an enabled provisioning cohort can install them without manual catalog inserts.
For each validated
environments.knownentry, execute oneINSERT ... ON CONFLICT (environment_ref) DO NOTHINGinside the existing inventory transaction. Existing rows, compatibility edges, and operator retirement are untouched. Missing, unavailable, and malformed observations cannot erase or partially publish the catalog.No advisory locks, catalog-admission quota, certification merging, JSON batching, or deferred-entry accounting. The existing desired-state recipe limit remains unchanged; operators retire old entries if the active catalog outgrows it.
The legacy upgrade reader skips profiles without kernel/snapshot metadata and recognizes known runtime aliases, so runtime-neutral rows cannot break unrelated activations and
fcmatchesfirecracker. Its query stays in the owning catalog store. Installation remains separate from execution permission; no cohort or upgrade flag is enabled.Depends on optional runtime components.
Validation
Final head
b2475c902passed 61 scoped tests on RemoteBox (catalog 4, publication 13, desired state 17, runtime upgrades 27), all-target scoped Clippy with warnings denied, isolated library checks, formatting, and secrets checks. Runtime-alias assertions added to existing attribution tests fail without the fix and pass with it. Architecture validation has zero required findings and two advisories: the pre-existing template-manager declaration and the intentional API-to-catalog-store ownership edge.Regression coverage:
published_known_environment_reaches_the_runtime_recipe_catalogproves registration reaches provisioning;registration_is_idempotent_and_preserves_existing_metadata_and_retirementcovers concurrent registration and existing-row preservation. Removed tests covered the discarded admission quota and certification merging, neither of which belongs to this insert-only operation; the existing oversized-recipe test remains passing.Fresh real-service proof passed at this head: run
space-runtime-fixture-0647200a041f, inner exit 0, no cleanup failures. Changing only the API binary on the same worker/database changed the actual Firecracker 1.17 binding CLI from exit 1 (missing artifact directory) to exit 0 after automatic installation. Firecracker/jailer/kernel hashes match their pins; non-API binaries are unchanged. Run-owned containers/network are gone and cgroup limits are unchanged. This is installation and binding proof, not local guest-VM boot.Pull CI and Kind Direct CI passed on final head
b2475c902. Direct-substrate typed smoke passed 51 ECW and 31 native scenarios with zero warnings, failures, inconclusive results, infrastructure errors, or accepted known failures. Earlier five-query batching results are historical and do not describe this implementation.The final CodeRabbit review's two outside-diff recommendations, admission quotas and batching, are deliberately deferred to keep registration simple. The existing 32-entry recipe guard remains fail-closed; operators retire old entries if that limit is exceeded. Per-definition inserts retain linear report cost but hold no global advisory lock.
Severity and risk
Severity: P2. Runtime definitions already reported by nodes were not entering the provisioning catalog, leaving installation recipes empty.
Risk: node reports can add catalog rows but never revise existing certifications or retirement. The existing oversized-recipe guard remains fail-closed. Nullable runtime-neutral metadata also requires the optional-components migration and null-safe legacy readers before publication.
For a cluster with runtime upgrades enabled: disable
SPACE_RUNTIME_UPGRADE_AT_ACTIVATION_ENABLEDacross old API/controller replicas, verify they have exited, deploy null-safe readers everywhere, then deploy the publisher before re-enabling upgrades. Disable upgrades before rolling readers back; stopping publication does not remove durable nullable rows. No live rollout is part of this PR.AI assistance: Perplexity drafted implementation, tests, documentation, and validation evidence; the admission-control and batching machinery was subsequently removed to keep this change insert-only.
