Scoped HTTP trigger routes

HTTP trigger management exposes TriggerService Apply/Get/List/Delete and GetTriggerOperation over the standalone node's management listener. The same route catalog is selected by the shared ingress for executable application routes and componentless static browser publication routes.

Application profile

HttpTrigger supports the closed buffered-v1 configuration: exactly profile, scheme, host, path, pathMatch, and method, all strings. Scheme is http or https; path matching is exact or prefix. Methods are explicit GET, HEAD, POST, PUT, PATCH, DELETE, or OPTIONS. Each record selects one method. HEAD never implicitly falls back to GET.

Host and path use the HTTP application's canonicalization: case/default-port aliases normalize before conflict detection. Routes cannot contain queries, wildcard hosts, encoded path separators, or regexes. A prefix matches a complete path segment (/api also matches /api/x, but not /apis). Non-root prefixes cannot end in /. The longest matching path wins; an exact match wins over a prefix at the same path. A stale winning route denies the request instead of falling back to a broader route.

The target must name a deployment route, its explicit tenant publication ID, content revision, and positive deployment object generation. default weighted routes are not supported. Only the latent:web/application@0.1.0 contract's handle function is accepted. Publication metadata, the compiled callable and current release eligibility must agree with this target and the trigger tenant. Tenant capsules may export this exact shared application interface; their capsule world and other owned exports still belong to their tenant namespace. Exporting the interface grants no host capability or execution permission.

Static browser publication profile

A static-web target is a separate authority variant:

apiVersion: latent.dev/v1alpha1
kind: HttpTrigger
metadata:
  name: customer-a-web
  tenant: customer-a
spec:
  target:
    kind: static-web
    publication: publication:sha256:<digest>
  configuration:
    profile: static-site-v1
    scheme: https
    host: customer-a.example.com
    path: /docs
    pathMatch: prefix
    method: GET

Static targets carry no service, contract, function, deployment, component, revision, deployment generation or renderer identity. Supplying any application target field together with kind: static-web is rejected. GET and HEAD are the only accepted methods.

The referenced publication must be an admitted BrowserAssets package whose signed web manifest contains a valid staticRouting record with profile static-site-v1. That record names only site-local public HTML documents and contains the entry-document, directory-index and fallback policy. Host/path ownership remains in the trigger rather than the signed package, so the same immutable publication may be mounted at different canonical external prefixes without changing its package identity.

Application and static targets occupy the same matcher table. Longest segment-bounded prefix and exact-over-prefix precedence are unchanged. After one winner is selected, a stale/revoked target denies rather than falling back to a broader row.

The external mount is stripped directly from the already canonical request path: / + /orders/123 yields /orders/123; /docs + /docs yields /; and /docs + /docs/guide/ yields /guide/. The node-reserved /_lsf namespace can never be captured by a static fallback.

A selected static route retains the exact tenant-scoped publication, web-manifest digest, asset-tree digest, web publication generation and a bounded WebSelection current-admission lease. It does not synthesize a ResolvedRevision. Publication currentness is checked again at the response acceptance boundary. Deleting the route does not revoke an already selected publication; revoking the publication does.

The control/selection contract in #495 intentionally stops before static response delivery. The dependent runtime work consumes this selected authority through the existing node-wide ingress and immutable asset store rather than creating a per-site listener, renderer or cache.

See the example template. Replace its illustrative publication, revision and generation with values from the intended deployment. This API requires an executable HTTP profile and an application target. Generic trigger declarations cannot establish a served route.

Scope, changes and receipts

All RPCs authenticate through the trusted transport context and require the existing tenant administrator policy. Manifest tenant and publication tenant must match that principal. Payload annotations and metadata cannot supply an actor or authorize another tenant. Get returns an absent record for a missing or foreign ID; Delete cannot remove another tenant's record. Trigger IDs are unique within a tenant. One canonical authority can be reserved by only one tenant across HTTP/HTTPS and methods; duplicate method/path/match-kind routes within that authority conflict. This is catalog ownership, not proof of DNS ownership. Public exposure still requires the ingress host/TLS policy in #229.

Apply/Delete require operation.operation_id, a present operation.expected_state_version, and a present expected_generation. Creation requires generation zero; update/delete require the current trigger generation. State version comes from Get/List or a committed receipt and is global to this catalog. Deployment, rollout and binding changes also advance that fence. The output-only Trigger.generation is not a precondition.

The catalog commits the canonical trigger, exact target identity and receipt in one file replacement. A trigger generation is its creation/update state version. Application identities retain publication, component, deployment, deployment generation and immutable revision. Static identities retain publication, web-manifest digest, asset-tree digest and web publication generation, with no placeholder execution fields.

Each accepted application request retains its original resolved revision, component, publication and route generation. Each accepted static request retains its exact web-publication authority and mount metadata. Later selection captures the new complete catalog. Already selected work still undergoes the target's normal current-eligibility check; deleting a trigger does not revoke its publication. Independent publications or tenants never share grants.

The most recent 64 operation receipts are retained across all trigger scopes. Within this window, exact replay returns the original receipt and Apply result without reactivating a deleted route. Reusing an operation ID with different normalized input, actor or CAS conflicts. Historical lookup is scoped by the authenticated tenant. UNKNOWN includes evicted receipts and is not proof that an operation never ran. An evicted request's old state CAS prevents silent reapplication. Do not resubmit an uncertain operation with new preconditions without inspecting current state. The global receipt window and version numbers do not grant node-wide inventory access.

Mutations require a configured durable audit owner. Success/error response capacity and the exact audit attempt are prepared before synchronous commit. The response reports catalog durability separately from the audit acknowledgement. Delete retains its original Empty response and adds bounded latent-trigger-operation-bin, latent-trigger-receipt, latent-trigger-state, latent-trigger-generation, latent-trigger-replayed, and latent-trigger-durability metadata, alongside audit metadata. Use the operation lookup RPC for the full receipt.

Recovery and resource ownership

Catalog format 7 adds the optional HTTP table. Catalogs without HTTP state retain their existing format 5/6 encoding. All deployment, rollout and capability-binding writers preserve the HTTP table under the same catalog transaction fence. Interrupted staging leaves the previous complete state. After a rename with uncertain directory sync, memory reflects the same new complete state, but new HTTP selections and mutations deny until successful recovery. Recovery verifies canonical manifests, target-variant receipt associations and checksums; it never treats an old receipt as current permission. HTTP table and receipt format v2 are required. Obsolete v1 tables, receipts and flat execution fields are rejected without rewriting the stored catalog. Restore a current-format snapshot or explicitly recreate state using the fresh-state procedure. Mixed/corrupt variant records fail closed. Stale or revoked targets remain inspectable and deletable. Pending trigger audit attempts reconcile through retained receipts; terminal Unknown audit records are not rewritten.

Management settings may impose smaller limits. Page tokens bind tenant, service filter, page size, catalog transaction and catalog owner. Edits or reopening invalidate them. Output owners retain charges through deferred encoding and delayed transport frames. A selected target retains a bounded read lease, and a prepared update reserves capacity before cloning the table. The existing catalog's configured state-file/compilation limits separately bound the combined serialized transaction; these numbers are not process RSS limits.

Dormant triggers retain bounded metadata only. There is no per-trigger listener, thread, task, execution cell, or guest instance. No bulk/load benchmark is needed for this metadata and authority contract.
