ekklesiaandClaude Opus 5 a02deb9433 feat: publish validated module UI artifacts at a platform-owned URL
CI / verify (pull_request) Successful in 32s
CI / infrastructure-smoke (pull_request) Successful in 13s
CI / migration-smoke (pull_request) Successful in 41s
Phase 6C pass 1. ADR 0024 named the one thing missing between the module UI
build pipeline and the generic host loader: Core resolves entrypoints.ui to an
absolute server filesystem path, and a browser needs a URL. This adds that
publication layer.

Core owns the policy. createModuleUiPublicationRegistry builds, from the
discovered and started module inventory, the answer to "may this be published,
and which exact file is it?" — publishable means the module survived discovery
and declares entrypoints.ui, with no new lifecycle state and no installer.

apps/api owns the transport: GET /api/v1/module-ui/<module-id>/<version>. Both
segments are lookup keys, not path components. An exact match yields the
canonical artifact path discovery already validated; no request value is ever
composed into a filesystem path, and the route declares no wildcard segment, so
traversal, encoded separators, sibling chunks, package-root files, and source
maps are unreachable by construction. An installed module directory never
becomes a static file root.

The prefix is a sibling of /api/v1/modules/, not a child: `ui` is a legal module
route segment, so a module registering GET /ui/:version would otherwise compete
with the platform for one URL with routing order deciding the winner.

The route requires no authentication, deliberately. Fetching the bundle confers
no authority, and a cookie-gated route would break cross-origin import(), which
sends none. The cost is stated rather than hidden: a caller who knows a module
id and its exact version can download that bundle. The three failure modes
return one identical 404 so the route is not an enumeration oracle.

Caching is no-cache with a strong SHA-256 ETag and RFC 9110 If-None-Match
handling, not immutable: without an installer nothing stops a version being
rebuilt with different bytes. The server reads bytes and writes bytes — never
imports, evaluates, or transforms the artifact.

Nothing mounts a module UI. A host could now obtain a URL, which was previously
impossible; there is still no Dashboard shell, navigation, or metadata endpoint.

ekklesiaandClaude Opus 5 800ecfdb92 fix: reject ambiguous module routes
A module can register both `GET /events/:id` and `GET /events/new`. Driven
through the pinned router, `/events/new` reached the parameter handler under
`demo.events.read` when the parameter route registered first, and the static
handler under `demo.events.create` when it registered second. Nothing rejected
the pair, so declaration order decided which permission guarded the path. That
is a permission policy, not a routing preference, and it must not be inferred
from array position.

Two routes of one module now overlap when they share a method and a segment
count and, at every position, either both segments are the same static literal
or at least one is a parameter. Under this grammar — static literals or `:name`
parameters, no wildcard, regex, optional, or catch-all — that is exactly "some
concrete request path matches both". `moduleRoutesOverlap` implements it in the
contracts package, where path semantics already live and Hono cannot reach.

Core checks it during staged registration, after the existing duplicate check,
so identical shapes (including paths differing only in parameter name) keep
returning MODULE_ROUTE_DUPLICATE and a genuine intersection returns the new
MODULE_ROUTE_OVERLAP. The rejected module publishes none of its staged routes or
capabilities, no start hook runs, and no listener binds. Rejection rather than a
specificity rule: ranking static above parameter would still silently pick which
permission applies. Disjoint routes keep their order; different methods,
different segment counts, and the same local path in two different modules
(each has its own platform-owned mount prefix) all remain legal.

The same requests also pinned down what handlers actually receive. Route
declarations are validated; route *parameters* are not, and the two are
unrelated. A single encoded segment arrives decoded as `/../admin`, `a\b`, an
embedded NUL, CR/LF, `1; drop`, or non-ASCII text — none of which any declared
path could contain. The contract now says so explicitly: decoded values are
untrusted, module-owned input that a handler must validate against its own exact
domain grammar before any database, filesystem, command, or identifier use, and
re-encoding is not a substitute. No generic validator, path-normalization layer,
or route field was added, because module parameters are module-owned domain
types and one platform-wide pattern would either reject legitimate values or
approve meaningless ones.

ekklesiaandClaude Opus 5 5c589d8fec fix: enforce explicit grant invariants
Explicit-grant management could produce states an operator could not reason
about, and pushed request-shaped problems into the database.

Two identical createGrant calls produced two grants; five concurrent identical
calls produced five. Revoking one returned success while the equivalent kept
authorizing the same user — an operator could believe they had removed access
that was still live. Two issuances are now the same authorization source when
user_id, permission_id, scope, source_kind, and source_ref are all equal, with
NULL equal only to NULL; expiry, creation metadata, actor, and grant id do not
distinguish them. Creating one while an equivalent is currently effective fails
with AUTHORIZATION_GRANT_ALREADY_EXISTS (HTTP 409, no-store) naming nothing about
the grant that already exists, and writing no grant and no audit row. A revoked
or expired equivalent does not block a fresh issuance. Conflict rather than
idempotent return: the caller asked to record a new authorization with their own
actor and expiry, and answering "done" while recording neither would hide that
nothing happened.

Enforcement is database-backed, since nothing constrains the number of API
processes: every create and revoke touching one equivalence tuple takes a
transaction-scoped advisory lock keyed by a hash of that tuple, encoded as a JSON
array so NULL stays distinct from the empty string and a crafted scope cannot
forge a separator. A collision can only make unrelated tuples serialize, never
hide a conflict, because the decision is always an exact SQL predicate. Its
single-key lock space is verified disjoint from the two-key space the migration
runner and bootstrap use. A time-dependent partial unique index was rejected:
now() is not immutable and cannot be indexed.

One revocation now clears every unrevoked equivalent — including expired-but-
unrevoked legacy rows, so the history is left in one state — with one audit row
per grant actually revoked, each carrying its own id, in one transaction.
Differently scoped or sourced grants are untouched. Historical duplicates are not
silently revoked by migration; the store prevents new effective equivalents and
an operator's explicit revocation resolves the class.

The request boundary no longer leaks into PostgreSQL. GrantId accepts exactly the
canonical lowercase hyphenated UUID the database emits, with no trimming and no
case folding, so a malformed path parameter is a 400 decided after authorization
but before any store call instead of reaching the UUID comparison and returning
an indistinguishable 503; a canonical unknown id still returns 404. expiresAt
accepts exactly YYYY-MM-DDTHH:mm:ss.sssZ, byte-for-byte equal to the parsed
date's own toISOString, and must be strictly future — bare new Date silently
rewrote 2026-02-31 to March 3rd and accepted locale, date-only, offset, and
millisecond-free forms, and a past expiry was stored as a grant dead on arrival.
The store validates the same thing before any SQL so trusted internal callers get
the guarantee too.

The generic HTTP surface now rejects a scope field in every form, including null.
No route middleware supplies a scope to the evaluator, so a scope accepted here
produced a grant that persisted, listed, and authorized nothing. Core's scope
semantics are unchanged for internal callers; no resolver was added.

Listing was unbounded and returned a user's entire history. It is now keyset
pagination over created_at DESC, id DESC with a strict boundary on both values,
so rows sharing a timestamp are neither skipped nor repeated, at most limit + 1
rows read, explicit-source filtering server-side on every page, and an opaque
unsigned position cursor that is strictly decoded and reveals nothing on
rejection. Core's list method requires a validated finite bound with no
unbounded fallback anywhere.

ekklesiaandClaude Sonnet 5 d3c6bd73d3 fix: enforce API request limits
Add a single platform-owned request-body policy (hono/body-limit) with
small, named limits for Better Auth and Core's grant-mutation endpoint, and
a new required maxBodyBytes field on the executable module route contract so
every module route makes a conscious no-body-or-bounded-body choice, capped
at a platform ceiling. Every oversized request gets one sanitized 413
contract and never reaches business logic, authorization, or a handler.
Also configure finite Node header/request/keep-alive timeouts, including the
non-obvious connectionsCheckingInterval needed for them to take effect
promptly, so a slow-header or slow-body connection cannot hold a socket
indefinitely.

ekklesia 0e308eb9ad feat: define module database access
Introduce ModuleDatabase (a typed, restricted Drizzle query surface) and the frozen
ModuleRuntimeServices boundary in @ekklesia/contracts, and thread the same services object
through Core's module start/stop lifecycle hooks and apps/api's authorized module HTTP handler
context. apps/api builds the facade via a new core/src/modules/database.ts view (createModuleDatabaseView)
over the one existing shared PostgreSQL pool, alongside the identity and authorization views, and
wires it into startApi's fixed startup order ahead of Identity/Authorization construction.
Registration stays database-free; a module reaches its database only through an authorized start,
stop, or HTTP handler invocation.

ekklesiaandClaude Sonnet 5 300f98c29d fix: normalize final CORS Vary headers
CI / verify (pull_request) Successful in 26s
CI / infrastructure-smoke (pull_request) Successful in 20s
CI / migration-smoke (pull_request) Successful in 27s
Found during a targeted post-audit review: sanitizeModuleResponse's Vary fix
(bf76f4e) canonicalized the module response's own Vary before Hono's own
cors() middleware (apps/api/src/app.ts) ran, but cors() unconditionally
appends its own "Vary: Origin" afterward, outside module-http-routes.ts's
reach. The wire-level response app.fetch actually returns could therefore
still read "*, Origin" for a module handler that sets Vary: *, or carry a
case-different duplicate Origin token — reproduced first via a new app-level
regression test hitting the final response, not sanitizeModuleResponse in
isolation.

Fixed by wrapping the shared corsMiddleware in withCanonicalVary
(apps/api/src/app.ts), which re-canonicalizes whatever Vary cors() leaves
behind only after it has fully finished, handling both the normal
next()-driven path (via c.header(), since reassigning c.res triggers Hono's
own header-preserving merge and would silently undo the fix) and the
OPTIONS-preflight path (cors() returns a Response directly without touching
c.res). Neither path reads or clones the response body.

Refactored module-http-routes.ts's Vary logic into one shared parsing/dedup
primitive with two policy-specific callers: mergedVaryHeader (module
responses; always forces canonical Origin/Cookie, unchanged behavior) and
the new canonicalizeVaryHeader (the app-level CORS boundary; only
deduplicates and collapses "*", never injects a token that was not already
present — an OPTIONS preflight has no Cookie/personalization concept to
force). This also incidentally fixes the same pre-existing Origin
duplication on /api/v1/principal (present since Phase 4B, flagged as a
remaining concern in the prior pass), since it wraps the one shared
middleware every /api/v1/* and /api/auth/* response already passes through.

ADR 0015 required no changes: its Vary/CORS ownership statements are
architectural, not tied to a specific function, and remain accurate.

ekklesiaandClaude Sonnet 5 bf76f4e006 fix: collapse invalid Vary * combination and case-duplicate tokens
Found during the Phase 5B pass-3 architectural audit: sanitizeModuleResponse's
Vary merge used a plain Set, so an existing "Vary: *" from a module handler
became "*, Origin, Cookie" (RFC 9110 §12.5.5 forbids combining "*" with any
other value), and a differently-cased existing token (e.g. "origin") produced
a redundant duplicate alongside the forced "Origin"/"Cookie". mergedVaryHeader
now de-duplicates case-insensitively, always emits canonical Origin/Cookie
casing, and collapses to a bare "*" whenever one is present, per focused unit
tests. The full app's own pre-existing cors() middleware (apps/api/src/app.ts,
unchanged here, present since Phase 4B on every /api/v1/* route including
/api/v1/principal) still unconditionally appends its own "Vary: Origin"
outside this module's control — noted in the new tests, not addressed by this
narrow fix.

ekklesiaandClaude Sonnet 5 dfaf324a65 feat: mount module HTTP routes
Phase 5B, pass 2: production API mounting, authorization enforcement,
and module-runtime lifecycle integration.

apps/api now discovers the installed module inventory exactly once
(prepareStartupModuleInventory), composes the platform permission
registry from it, starts the module runtime from that same discovered
list (startDiscoveredModuleRuntime, never rediscovering), and mounts
StartedModuleRuntime's published routes under
/api/v1/modules/<module-id> via a new apps/api-owned Hono adapter
(module-http-routes.ts). Every module route is protected by the
existing requirePermission middleware against the composed registry,
state-changing methods additionally require a trusted Origin, OPTIONS
remains entirely platform-owned, and a handler that throws, rejects,
or returns a non-Response becomes a fixed, sanitized
500 MODULE_HANDLER_FAILED. Module-supplied CORS headers are stripped
and every module response is forced to Cache-Control: no-store with
Vary: Origin, Cookie. RunningApi shutdown now stops the module runtime
between draining the HTTP server and closing the shared pool, and
every startup failure path stops the runtime and/or closes the pool
before propagating, without masking the original failure.
