Changes

  • The dev studio server no longer answers fetch() with its own document. Its history fallback served the SPA document for every path it does not handle itself, so a programmatic request for an app REST route came back as a 200 carrying the studio's HTML — which the API console rendered as a successful response. Non-navigation requests (Sec-Fetch-Mode present and not navigate) now reach the worker through the existing proxy, loopback-only; deep-link navigations still get the document, and a client sending no such header keeps the fallback.
  • Try-it REST dispatch targets the worker. The API console's plain-REST branch fetched operation.httpPath same-origin with no Authorization header. Under lunora dev the studio server answers every non-/_lunora/* path with the SPA document as a 200, so pressing Send on any REST route rendered the studio's own HTML as a "successful" response; under the Vite host guarded routes 401ed. The branch is extracted into restDispatch, which resolves the path against the worker origin (client.url) and sends Authorization: Bearer <admin token> when a token is set. RPC dispatch is unchanged.
  • Unit-project coverage is gated again. Studio's coverage thresholds were zeroed (the full jsdom component run stalls under v8 coverage) and the package was excluded from both root coverage queries. The pure-node unit project does not stall, so test:coverage now runs vitest run --project unit --coverage and the thresholds pin its measured floor (statements 10 / branches 9 / functions 7 / lines 11 — coverage counts all of src, so component-only files sit at 0%). project!=studio is removed from the root test:coverage / test:affected:coverage queries; the component project stays deliberately ungated.

Merge note

This PR and #449 both edit packages/bindings/src/images/signed-delivery-url.ts in overlapping regions (the header/import block, and the TTL guard #449 replaces). A conflict on the second merge is guaranteed and needs a real re-resolve — read both sides rather than taking either wholesale.

Verification

  • pnpm --filter "@lunora/studio" run test — 1080/1080 pass (125 files). Earlier runs on a heavily contended machine dropped 1-3 jsdom tests (command palette / studio navigation timeouts); the same tests fail identically on the unmodified base commit under load and pass on an uncontended run, so they are load flakiness, not regressions — none were skipped or modified.
  • pnpm --filter "@lunora/studio" run test:coverage — exits 0 at the pinned floor (measured: statements 11.13% / branches 9.56% / functions 7.52% / lines 11.15%).
  • Gate proven live: raising the lines threshold to 12 fails the run with ERROR: Coverage for lines (11.01%) does not meet global threshold (12%), then reverted.
  • New rest-dispatch.test.ts (5 tests): absolute URL on the worker origin, bearer present with a token, absent without one, the dispatch driven by a client built the way app.tsx builds it, and an absolute httpPath refused rather than carrying the bearer off-origin.
  • New studio-server tests: a Sec-Fetch-Mode: cors request for an unknown path reaches the worker and returns no HTML; a navigate request for a deep link still gets the document and never contacts the worker. The first fails against the pre-fix server (verified by stashing the fix).
  • pnpm --filter "@lunora/cli" run test — 1259/1259. lint:types + lint:eslint green for both @lunora/studio and @lunora/cli; pnpm run lint:package-json green.
  • grep -n "await fetch(operation.httpPath," …/run-context.tsx — no match; grep -c "project!=studio" package.json — 0.

Walkthrough

The change centralizes REST dispatch and origin validation, integrates it into OpenAPI operations, routes loopback non-navigation requests to the worker, adds proxy timeout handling, and updates unit coverage configuration.

Changes

REST and studio request flow

Layer / File(s) Summary
REST target resolution and dispatch
packages/studio/src/lib/rest-dispatch.ts
REST paths are normalized before validation and fetching. Empty origins use the console location. Host-naming paths and cross-origin targets are rejected. Responses return parsed JSON or text.
REST operation integration
packages/studio/src/features/api/openapi/run-context.tsx
Plain REST operations use restDispatch. Lunora function-path operations continue to use dispatchByKind.
Loopback worker routing
packages/cli/src/util/studio-server.ts
Loopback requests with non-navigation Sec-Fetch-Mode values use worker responses or 404 responses. Navigation requests and requests without the header retain SPA fallback behavior.
Proxy lifecycle handling
packages/cli/src/util/studio-server.ts
Proxied requests use stream pipeline handling, a 30-second timeout, 504 responses for timeout errors, 502 responses for other errors, and upstream cancellation after client disconnects.
Unit coverage configuration
packages/studio/vitest.config.ts, packages/studio/package.json
The REST dispatch test is included in the unit project. Coverage runs only the unit project with measured coverage thresholds.

Estimated code review effort: 3 (Moderate) | ~25 minutes

@prisis prisis changed the title fix(studio): route try-it to the worker, gate unit coverage fix(studio): route try-it to the worker Aug 21, 2026
prisis and others added 4 commits August 24, 2026 11:29
The API try-it console's plain-REST branch fetched
`operation.httpPath` same-origin with no Authorization header. Under
`lunora dev` the studio server answers every non-/_lunora path with
the SPA document as a 200, so pressing Send rendered the studio's own
HTML as a "successful" response; under the Vite host guarded routes
401ed. The branch now targets the worker origin (`client.url`) and
sends the admin bearer when a token is set, via an extracted
`restDispatch` covered by a fetch-stub test.

The studio's coverage thresholds were zeroed and the package excluded
from both root coverage queries because the full jsdom component run
stalls under v8 coverage. The pure-node `unit` project doesn't stall,
so `test:coverage` now runs `--project unit --coverage` and the
thresholds pin its measured floor (statements 10, branches 9,
functions 7, lines 11 — coverage counts all of src, so component-only
files sit at 0%). Root coverage queries include studio again. The
component project stays ungated; the gate was proven live by raising
lines to 12 and watching the run fail.

The try-it console's REST transport lived in the React context module
and was exported only so a test could reach it. It moves to
`src/lib/rest-dispatch.ts`, next to the `dispatchByKind` that carries
the RPC half, with the operation typed structurally so `lib` keeps no
dependency on the API feature. The test moves to `__tests__/lib/` and
joins the DOM-free `unit` project, putting the logic under the
coverage floor. Behaviour is unchanged.

Claude-Session: https://claude.ai/code/session_01P2mHUwAGcpzDrv4ZNd8MLG
The studio server's history fallback answered every path it does not
serve itself with the SPA document, including programmatic requests.
A `fetch()` for an app REST route — what the API console's "try it"
sends for a plain `httpRouter()` operation — therefore came back as a
200 carrying the studio's own HTML, which the console rendered as a
successful response. Routing the call to the worker origin was not
enough on this host: the studio server is the origin, so the request
never left it.

Non-navigation requests (`Sec-Fetch-Mode` present and not `navigate`)
now go to the worker through the existing proxy, on loopback only, so
the route answers for itself. Deep-link navigations still get the
document, and a client that sends no such header keeps the fallback.

Also refuse an absolute `httpPath` that resolves off the worker
origin, so an OpenAPI document cannot walk the admin bearer to
another host, and cover the try-it dispatch with the client built the
way the app builds it rather than a hand-passed origin.

Four threads from the review, each fixed at its cause.

**The bearer could leave the origin.** `restDispatch` only checked the resolved
URL when `origin` was non-empty; the empty case fetched `operation.httpPath` as
written, so an absolute or protocol-relative path in the OpenAPI document chose
its own host and the admin bearer went with it — the exact thing the guard
exists to stop, reachable through the one branch that skipped it. Both cases now
run through `resolveTarget`: an empty `origin` means "the console's own origin"
(`location.origin`), and where there is no `location` to resolve against a path
that names its own host is refused rather than sent. Two regression tests, both
verified to fail against the previous code.

**The REST dispatch branch had no test.** `OperationRunProvider` now has one
that renders an operation with no `functionPath` and asserts the console
forwards the operation, its parsed args, the worker origin AND the bearer — the
mock client gained the `url` / `getAuthToken` the console reads.

**`proxyHttp` could hang or outlive its client.** It had a 502 arm for a worker
that refuses the connection but nothing for one that accepts and never answers,
and it left the upstream request running when the browser aborted. Bounded by
`PROXY_RESPONSE_TIMEOUT_MS` (surfacing 504), the upstream is destroyed when the
response closes unfinished, and an error after headers are sent drops the
connection rather than appending prose to a partial body. Regression test
included; it hangs for the full timeout against the previous code.

**The docblock oversold the proxy.** Both proxy legs are loopback-only — off
loopback the server is a read-only shell — which the code said and the file
header did not.

Follow-up to the guard added in e36548f, which the review then walked around.

**The guard tested a string `fetch` never sees.** WHATWG URL parsing trims
leading and trailing C0-and-space and removes every ASCII tab, CR and LF from
anywhere in the input, so `"  http://evil.example/steal"` and
`"htt<tab>p://evil.example/steal"` both failed the "names its own host" test and
were then fetched as `http://evil.example/steal` — with the admin bearer. The
path is normalized to what the parser will produce, and that same normalized
value is both tested and sent, so the string checked is the string dispatched.

Written with explicit scans rather than a regex: the trim needs the full
`\u0000`-`\u0020` range (`String.trim` stops short of the C0 controls, which
would have left `"\u0001http://…"` a hole), and a character-class quantifier
over that range is what `sonarjs/slow-regex` refuses.

**A truncated upstream body left the browser holding an open response.** A
worker that dies after its headers closes `upstreamResponse` without the request
emitting an error, so the bare `pipe` never tore the downstream down and the
partial body read as complete. `pipeline` destroys both ends.

Two regression tests for the bypasses, both confirmed to reach `fetch` against
the previous commit.

### ⚠ BREAKING CHANGES

* **server:** previously-accepted `contains` on non-string filter
columns is no longer honoured. Consistent with the module's allow-list
mechanism (v.object strips undeclared keys), the key is stripped/dropped
rather than rejected with a validation error — the predicate never
reaches the SQL compiler. Alpha branch, no back-compat shim.

* fix(server): redact camelCase and lowercase secret keys

redactSecrets' keyed-value pass matched any identifier key but tested it
against an uppercase-only suffix regex, so exactly the spellings that
appear in request bodies and thrown errors (password, apiToken,
authSecret) fell through unredacted unless the value happened to hit a
prefix or entropy heuristic.

The suffix regex now matches key/password/secret/token as a real word in
SCREAMING_SNAKE, lower snake/bare, or camelCase form, with a boundary so
MONKEY/monkey/donkey (suffix mid-word) no longer match — the old regex
redacted MONKEY=..., a false positive the boundary removes rather than
extends. Camel-hump keys like sortKey are deliberate over-redaction.

The duplicated regex in @lunora/config's .dev.vars scaffolder (and its
test mirror) is kept byte-identical per the existing cross-reference
comment.

surface; the wrapping loop's untyped (unknown) return would let a future
async/await refactor silently turn ctx.storage.getUrl into a Promise for
guarded procedures only. Document the invariant at the declaration and
pin it with a test asserting the wrapped call returns a plain string,
not a thenable. No behaviour change.

* perf(server): bound presence reads and self-reap

listPresent collected every row a room had ever accumulated (the TTL is
a read-time filter that hides stale rows but never deletes them) and the
sweep is an internal mutation nothing schedules by default, so an app
that skipped wiring a cron degraded as O(live-set x historical-rows) per
TTL window — on the hottest query in the module, re-run for every
subscriber on every heartbeat.

Two local fixes:
- a (roomId, lastSeen) index and a maxMembers option (default 512):
  listPresent now reads newest-first with a hard cap, so cost scales
  with the cap, not with rows ever written; the in-memory sort is gone
  since index order already delivers newest-first.
- the heartbeat opportunistically reaps up to 8 of its room's oldest
  rows per beat, using a cutoff a full max(grace, ttl) window behind the
  visibility cutoff so a row the read filter could still show — or a
  grace-window reconnect could revive — is never deleted. Active rooms
  self-clean; sweep remains as optional bulk hardening.

* fix(server): unify the secret-key rule in shared/

Four copies of the "does this key name imply a secret" regex existed —
the runtime redactor, the .dev.vars scaffolder, `lunora deploy`'s
required-secret resolver and `lunora doctor` — kept in step only by a
comment. Two had just been updated for camelCase keys and two had not,
so `apiToken` in a .dev.vars was a secret to the runtime and ordinary
config to the CLI.

They are now one definition in shared/secret-key.ts (zero-dep,
bundler-inlined, so no dependency edge between the app runtime and the
CLI/config layer).

The rule also fixes a regression the boundary-based regex introduced:
requiring `^`/`_`/`-` immediately before the suffix silently stopped
matching no-separator compounds the original caught — OPENAI_APIKEY,
APITOKEN, MYPASSWORD, AUTHSECRET — leaving a short or low-entropy secret
under one of those names unredacted in logs and unminted by the
scaffolder. Matching is now a plain case-insensitive suffix, which also
picks up the Title-case and kebab spellings (Api_Key, Auth-Token) the
previous doc claimed to cover.

MONKEY/monkey/donkey stay excluded by an explicit word list rather than
a boundary rule: MONKEY and APIKEY are structurally identical, so no
positional rule can separate them, and the word list is the only honest
way to keep both properties.

* fix(server): treat enum columns as string filter columns

Gating `contains` on `validator.kind` alone judged an enum column —
`v.union(v.literal("open"), v.literal("closed"))`, kind "union" — and a
bare `v.literal("x")` as non-string, so the operator was omitted from
the generated validator. Because `v.object` strips an undeclared key and
an emptied predicate is dropped, `?where[status][contains]=ope` against
an enum column silently returned the UNFILTERED set rather than failing
— a silent widening wherever a list filter is doing the scoping.

A union now counts as string-typed when every member is (v.null()
members are transparent, so a nullable string union qualifies); a mixed
union still refuses, since `contains` would otherwise reach non-string
values.

* fix(server): name the presence cap for sessions, not members

The bounded `listPresent` read caps SESSION ROWS — one per (roomId,
sessionId), so one per open tab — but the option was called maxMembers
and documented as a member cap, and the multi-tab dedup runs after the
read. A 300-person room at two tabs each is 600 rows, so the 512 default
silently truncated ~90 live, currently-heartbeating users out of "who's
here" where the previous unbounded read was complete.

Renamed to `maxSessions`, documented as a session cap to be sized
against expected tabs, and the default raised to 1024. A non-finite
value now falls back to the default instead of reaching the reader as
`LIMIT NaN` (Math.max(1, Math.floor(NaN)) is NaN).

* fix(server): redact any key ending in a secret suffix

The word list excluding ordinary "-key" words (MONKEY, DONKEY, …) is
gone. It never delivered the property it claimed — turnkey, hokey,
lowkey and smokey all end in "key" and were absent, so the list bought
the appearance of precision and none of it, while being unbounded and
unjustifiable to the next reader.

MONKEY and APIKEY are structurally identical, so the only question is
which way to fail. For a redactor over log and error text, over-
redaction is the safe direction: masking a variable named MONKEY costs
one confusing log line, missing APITOKEN costs the credential. The
JSDoc now states that as the deliberate trade, and the tests assert
MONKEY/monkey/sortKey ARE redacted.

The one consumer that writes rather than logs is safe under over-
matching too: the .dev.vars scaffolder mints a value only where the
example held a placeholder, so an over-match fills a placeholder the
user had to fill anyway and never overwrites a real value.

* test(server): suppress the redaction fixture on the secret scanner

`MYPASSWORD=abc` is an input to a redaction assertion, not a credential, but
the scanner reads the assignment shape and fails the Secrets job. Marked with
`gitleaks:allow` the same way the other redaction and column-name fixtures in
this repo are.
