fix: tier 0-1 security and correctness sweep — storage secret, proto pollution, float money, cache invalidation by sebyx07 · Pull Request #80 · developerz-ai/ultimate

sebyx07 · 2026-08-15T06:34:42Z

Tier 0–1 half of a four-PR audit sweep. Every finding was reproduced by running the code before it was fixed, and every fix ships a test verified to go red on the old code.

Merge order is tier order: this lands first, then tier 2, tier 3–4, and the gate/CLI slice adopt it.

Security

Where	Defect
`storage/src/driver-local.ts:76`	The local disk fell back to the hardcoded, published string `'ultimate-dev-signing-secret'` when `STORAGE_SIGNING_SECRET` was unset. Anyone could mint a `PUT` grant offline with a `maxBytes` and `contentType` of their choosing, and `acceptSignedUpload` trusts the signed constraints over the app's `uploadPolicy` — so a 200 KB avatar grant became an unlimited upload of any type. Now `localDriver` throws at construction outside a local environment, and exports `usesDevStorageSecret()` so `x doctor` can report it (wired in the gate/CLI PR, mirroring the existing `usesDevCursorSecret`).
`storage/src/driver-local.ts:74`	The sidecar namespace `<root>/.meta/<key>.json` overlapped the object namespace and `assertSafeKey` did not reserve it. `put('.meta/a/b.json', …)` — a legal key — overwrote the metadata for `a/b`, so `head('a/b')` reported an attacker-chosen `contentType` and a route serving that object returned attacker HTML from the app's origin. `.meta` is now reserved on every driver.
`schema/src/validators.ts:242`	`t.record` built its output on an `{}` literal, so a `__proto__` key set the prototype instead of a property. `t.record(...).validate(JSON.parse('{"__proto__":{"a":"pwned"}}'))` yielded `value.a === 'pwned'` with `Object.keys(value)` empty — any handler reading `input.settings[k] ?? default` got the attacker's value for keys the request never sent. Now built on `Object.create(null)`, with `__proto__`/`constructor`/`prototype` refused outright.

Correctness

Where	Defect
`money/src/arithmetic.ts:42`	`multiply` scaled in IEEE-754 before rounding, so the rounding mode saw a value already off by an ULP. `multiply(money(100,'EUR'), 1.005)` returned €1.00 — `100 * 1.005 === 100.49999999999999`, where the exact answer 100.5 must round to 101. A 0.5% fee on €1.00 was silently free. Scaling now reaches the mode as an exact bigint rational (`factor.ts`). `divide` had the same defect class and is fixed with it — leaving it would have made `multiply(x, 0.1)` and `divide(x, 10)` round differently.
`i18n/src/context.ts:52`	`DEFAULT_ORDER` put `header` first, so `Accept-Language` outranked the explicit language-switcher cookie, the stored user preference and `?locale=`. A user who picked Spanish in the switcher got English forever. `@ultimat3/http`'s negotiator already checked explicit first, so the framework's two locale resolvers disagreed. Now `query → cookie → user → header`.
`cache/src/redis.ts:41`	A named known gap in CHANGELOG.md, now closed. The Lua invalidation script `DEL`'d value keys read out of `SMEMBERS` without declaring them in `KEYS`. On Redis Cluster or Dragonfly the whole invalidation aborted, was swallowed into `report.errors`, and stale rows served until TTL — while the report read "partial" and the triggering write still succeeded. The script now returns the member list; the tier deletes client-side, one key per `DEL`, so every delete is slot-local.
`cache/src/tiers.ts:91`	Read-through promotion rewrote a hit into every closer tier with `options.ttlMs`, discarding the entry's own `expiresAt`. A value one second from expiry got a fresh five-minute lease on every read, so a hot key served stale data indefinitely. `isExpired` was exported and unit-tested but never called by the stack; it is now actually called.
`cache/src/lru.ts:127` vs `redis.ts:103`	`ttlMs: 0` meant "never expires" in the memory tier and "one second" (`EX 1`) in Redis — so a stack holding both answered differently depending on which tier hit. One rule now: a TTL must be a positive finite number of milliseconds (`X_CACHE_TTL_INVALID`). "Do not cache" is expressed by not declaring a `cache` block.
`cache/src/invalidate.ts:142`	`report.cdn` was folded into the event log's `busted` list, but nothing ever purged those paths — the CDN tier purges by surrogate key, not by `cdn-path` dependents. `x cache bust --json` reported `/blog/hello` as busted while the CDN still held it for its full `s-maxage`. A partial bust read as a clean one — exactly what the module header says it exists to prevent. The tier now purges `cdn-path` dependents, and `busted` is built only from what actually cleared.
`schema/src/validators.ts:305`	`t.money` used `Number.isInteger` while `entity`'s `parseMinor` and `money()` both require `Number.isSafeInteger`, so `{minor: 2**53}` passed the boundary with a 200 and then threw `X_COLUMN_INVALID` at the repo write — a 500 for what should have been a 422 with a field path.
`schema/src/validators.ts:76`	`StringSchema.pattern` stored only `regex.source` and rebuilt with `new RegExp(node.pattern)`, discarding every flag: `t.string.pattern(/^[a-z]+$/i).parse('ABC')` failed, and the error quoted the pattern that would have matched. Flags now persist; JSON Schema states them in `description` rather than silently narrowing.
`money/src/convert.ts:109`	`fixedRateProvider.rateFor` ignored `at` and stamped its own table date, though `RateProvider` documents that a provider which cannot honour `at` must return `undefined`. A historical invoice reprice silently used today's rate and recorded a date nobody asked for.
`money/src/format.ts:46`	`formatMoneyParts` ignored `options.accounting` and passed the signed decimal to `Intl`, while `formatMoney` formatted `Math.abs` and prefixed the sign itself — so a UI styling the symbol via parts rendered `-€12.99` where the rest of the app printed `(€12.99)`. Sign and notation are now decided in exactly one place.
`db/src/readonly-query.ts:171`	Only a trailing `;` was stripped before splicing into `DECLARE … CURSOR FOR`, so an embedded `;` turned one statement into two and the second undid the `SET LOCAL statement_timeout` guard — while `guards` still reported `timeout:5000ms`. `BEGIN READ ONLY` held, so this was a defeated guard rather than a write, but the reported guard list was a lie. Now refused before `BEGIN`, on the direct path too.
`core/src/cursor.ts:41`	The cursor signing secret was read at module scope, against the call-time rule every other secret in the repo follows. An app loading secrets via `openSecrets()` during boot signed every cursor with the shipped dev key while `ULTIMATE_CURSOR_SECRET` was set. Now read inside `sign()`.
`core/src/ids.ts:54`	`randomBytes(2)[0]! & COUNTER_SEED_MASK` allocated two bytes and read one, so the "10-bit" seed could only produce 0–255 while `COUNTER_SEED_MASK = 0x3ff` declared ten bits.
`i18n/src/context.ts:98`	Unguarded `decodeURIComponent` on a per-request path: `Cookie: x-locale=%` threw a bare `URIError`.

Documentation corrected

CLAUDE.md — the four known gaps are now a table with real state. Two are closed by this sweep (the binary version read; the cache Lua script), two remain open and say why. The docker-compose.prod.yml port/replicas gap is restated correctly: it is web and sync, in three separate compose files, not just web.
wiki/I18n.md — documented the resolution order as header → cookie → user → query, which was both wrong and the opposite of what an explicit switcher needs.

Deliberately not fixed

resolveEnvironment exists in both core and seo with different return types — a real axiom-1 violation. Both are shipped public APIs with different return unions, so unifying them is a breaking change needing a major and an explicit decision. Named in CLAUDE.md as open rather than quietly fixed.

New error code

X_CACHE_TTL_INVALID — documented in wiki/Error-Codes.md, registered, in the manifest.

Semver

ttlMs: 0 now throws where it previously meant "never expires" (memory) or "one second" (Redis). No caller in packages/, examples/ or dummy/ passed it outside test fixtures. This is a behaviour break on a documented option and should not ship in a 1.x without an explicit decision.

Gate

bun run verify green on this branch alone: 14/17, with the same three structural skips as main (drift, contract-diff, budgets).

📝 Walkthrough

Walkthrough

The PR updates cache expiration and invalidation, cursor signing, UUID seeding, read-only SQL validation, locale precedence, exact money arithmetic, schema safety checks, storage security, package exports, manifests, and documentation.

Changes

Cache lifecycle and invalidation

Layer / File(s)	Summary
TTL validation and promotion `packages/cache/src/tiers.ts`, `packages/cache/src/lru.ts`, `packages/cache/src/errors.ts`, `packages/cache/src/tiers.test.ts`, `packages/cache/src/lru.test.ts`	TTL values must be positive and finite. Cache promotion preserves remaining expiration.
Redis and CDN invalidation `packages/cache/src/redis.ts`, `packages/cache/src/cdn.ts`, `packages/cache/src/invalidate.ts`, `packages/cache/src/*test.ts`	Redis deletes returned value keys client-side. CDN purges include dependent paths. Invalidation reports separate CDN dependencies from cleared tiers.

Core behavior

Layer / File(s)	Summary
Cursor signing and UUID seeding `packages/core/src/cursor.ts`, `packages/core/src/ids.ts`, `packages/core/src/index.ts`, `packages/core/src/*test.ts`	Cursor secrets resolve at signing time. UUID counter seeds use the full ten-bit range.
Actor facts documentation `packages/core/src/actor.ts`	ActorFacts usage and request-boundary resolution are documented.

Database and internationalization

Layer / File(s)	Summary
Single-statement read-only queries `packages/db/src/readonly-query.ts`, `packages/db/src/errors.ts`, `packages/db/src/readonly-query.test.ts`	Multiple SQL statements are rejected before transaction setup with `X_SQL_UNSAFE`.
Locale source precedence `packages/i18n/src/context.ts`, `packages/i18n/src/context.test.ts`, `wiki/I18n.md`	Locale sources use query, cookie, user, then header precedence. Malformed cookies no longer throw.

Money and schema validation

Layer / File(s)	Summary
Exact money arithmetic `packages/money/src/factor.ts`, `packages/money/src/rounding.ts`, `packages/money/src/arithmetic.ts`, `packages/money/src/*test.ts`	Scaling and rounding use exact fractions and bigint ratios.
Conversion and formatting `packages/money/src/convert.ts`, `packages/money/src/format.ts`, `packages/money/src/*test.ts`	Conversion uses rational scaling. Formatting delegates sign placement and accounting notation to `Intl.NumberFormat`.
Schema pattern and record validation `packages/schema/src/node.ts`, `packages/schema/src/validators.ts`, `packages/schema/src/json-schema.ts`, `packages/schema/src/validators.test.ts`	Regex flags are preserved. Prototype keys are rejected. Money minor values require safe integers.

Storage

Layer / File(s)	Summary
Reserved metadata namespace `packages/storage/src/path.ts`, `packages/storage/src/index.ts`, `packages/storage/src/path.test.ts`	Keys beginning with `.meta` are rejected.
Environment-specific signing secrets `packages/storage/src/driver-local.ts`, `packages/storage/src/errors.ts`, `packages/storage/src/driver-local.test.ts`	Local storage requires an explicit signing secret outside development environments.

Project metadata and documentation

Layer / File(s)	Summary
Manifest and roadmap status `framework.manifest.json`, `CLAUDE.md`, `wiki/Error-Codes.md`	The build identifier, cache error registry, roadmap status, and error documentation were updated.
Package contract documentation `packages/cache/README.md`, `packages/cache/CLAUDE.md`, `packages/core/README.md`, `packages/core/CLAUDE.md`, `packages/money/CLAUDE.md`, `packages/storage/README.md`, `packages/storage/CLAUDE.md`	Documentation records the updated cache, signing, money, and storage contracts.

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🟠 High · up to c064c

The PR improves storage security, validation, money arithmetic, locale handling, and cache behavior, but the current head still permits a published development signing key outside local environments, can misround inverse fixed-rate conversions, and can re-cache Redis data without its remaining expiry. These issues could enable forged upload grants, monetary discrepancies, or stale data, so merge should wait for the remaining fixes.

Inline comments:
In `@packages/cache/src/lru.ts`:
- Around line 115-123: Reorder the update logic in the cache insertion method so
assertTtl validates the replacement TTL before unlinking the existing node.
Preserve the existing entry when validation throws X_CACHE_TTL_INVALID, then
unlink it only after successful validation before creating the new LruNode.

In `@packages/cache/src/tiers.ts`:
- Around line 121-125: Update createRedisTier.get to read Redis expiry metadata
alongside the cached value and return the remaining expiry as expiresAt for
entries with a finite TTL, preserving undefined for non-expiring entries. Add a
regression test covering promotion from the Redis tier to ensure LRU promotion
uses the remaining expiry rather than the caller TTL.

Apply the same fix in `@packages/cache/src/redis.ts` around lines 114 - 118.

In `@packages/core/src/cursor.test.ts`:
- Around line 130-136: Update the test’s finally block after
configureCursorSigning('explicit') to call resetCursorSigning(), while
preserving the existing restoration of ULTIMATE_CURSOR_SECRET.

In `@packages/db/src/errors.ts`:
- Around line 166-172: Update the fix field in multipleStatements to provide a
pasteable, actionable readOnlyQuery call expression that demonstrates executing
one statement per call, rather than prose instructions; keep the existing error
code, cause, and metadata unchanged.

Apply the same fix in `@packages/money/src/rounding.ts` around lines 58 - 63: The
same non-runnable fix-value defect occurs on the zero-denominator rounding path.

Apply the same fix in `@packages/cache/src/errors.ts` around lines 86 - 96: The
same non-runnable fix-value defect occurs for invalid cache TTL errors.

In `@packages/money/src/convert.ts`:
- Around line 57-65: Preserve fixed exchange rates as exact fractions instead of
creating inverse decimal rates: update fixedRateProvider to retain the original
fraction and swap its numerator and denominator for inverse lookups. Change
convert and its factorFraction usage to consume that exact fraction through
ratio rounding, while keeping currency exponent scaling intact. Add a regression
test covering the large EUR-to-USD conversion with a 0.92 fixed rate and the
expected exact reciprocal result.

In `@packages/money/src/factor.test.ts`:
- Around line 1-2: Add a concise 1–4 line module header at the top of the factor
tests, before the imports, stating the test module’s responsibility and that it
protects decimal-to-fraction conversion behavior. Keep the existing imports and
test implementation unchanged.

In `@packages/storage/CLAUDE.md`:
- Around line 48-60: Update packages/storage/CLAUDE.md lines 48-60 to state that
non-local localDriver construction fails only when both the explicit
signingSecret option and STORAGE_SIGNING_SECRET are unavailable, while
preserving the test fallback. Update packages/storage/README.md line 146 to use
the same condition in the X_ENV_MISSING error table; keep both documents
consistent.

In `@packages/storage/src/driver-local.test.ts`:
- Line 136: Replace the local KEY constant in the test with the exported
STORAGE_SIGNING_SECRET_KEY imported from ./driver-local, and update its usages
so the test relies on the single shared environment-key definition.
- Around line 164-179: Update the test around localDriver to separately assert
that missing STORAGE_SIGNING_SECRET returns X_ENV_MISSING, then set it to
DEV_SIGNING_SECRET and assert production and staging construction are rejected
with the appropriate published-key error. Ensure the published-key assertion
actually invokes localDriver({ root }) with the key present.

In `@packages/storage/src/driver-local.ts`:
- Around line 100-104: Reject DEV_SIGNING_SECRET in non-local environments even
when provided via options.signingSecret or STORAGE_SIGNING_SECRET_KEY, using the
existing X_ENV_MISSING or replacement typed error; preserve the local
development-key fallback. Update the production/staging coverage in
packages/storage/src/driver-local.test.ts lines 164-179 to set
STORAGE_SIGNING_SECRET to DEV_SIGNING_SECRET and assert the expected error.

Apply the same fix in `@packages/storage/src/index.ts` around lines 42 - 47.

In `@packages/storage/src/errors.ts`:
- Around line 205-210: The signingSecretMissing error cause incorrectly
attributes the resolved environment to ULTIMATE_ENV. Update signingSecretMissing
so its message states only that the resolved environment is "${environment}",
preserving the existing error code, fix, and metadata contract.

In `@packages/storage/src/path.test.ts`:
- Around line 108-115: Add driver-boundary regression cases in
driver-local.test.ts and driver-s3.test.ts covering .meta/... keys, including
the scoped form where applicable, and assert each operation returns
X_STORAGE_PATH_UNSAFE. Keep the existing direct assertSafeKey coverage
unchanged.

In `@packages/storage/src/path.ts`:
- Around line 12-20: Keep META_DIR in packages/storage/src/path.ts as the sole
declaration and export owner, then update packages/storage/src/driver-local.ts
to import and reuse it instead of declaring a duplicate. Retain the ownership
statement in packages/storage/CLAUDE.md at line 31; no direct change is required
there.

- cache/lru: validate the TTL before unlinking, so a rejected overwrite keeps the entry it would have replaced - cache/redis: `get` reads PTTL alongside the value and reports `expiresAt`, so promotion into the LRU carries the remaining lease instead of re-leasing on the caller's ttl - money/convert: `ExchangeRate.ratio` keeps a derived rate exact — `fixedRateProvider` swaps the fraction instead of taking `1 / rate`, which lost a minor unit on large amounts - storage: the published DEV_SIGNING_SECRET is refused outside a local environment however it arrives (env var or `signingSecret`), and the cause names the environment `resolveEnvironment()` actually resolved - storage: `.meta` rejection pinned at both driver boundaries; the test reads the exported env-key constant - core/cursor test resets the explicit signing config in `finally` - three `fix:` values are pasteable call expressions, not prose - docs follow: cache, money and storage CLAUDE.md + README Co-Authored-By: Claude <noreply@anthropic.com>

…face agents actually hit Tier 5 and the build tooling — the last of a four-PR audit sweep, and the one that matters most: **several findings are holes in `bun run verify` itself.** A gate step that silently passes is worse than no step, because it is read as coverage. **Stacked on #80** — the doctor check consumes a storage export from it, and `noNonNullAssertion` could only be raised once its `ids.ts` fix landed. ## Gate holes closed | Where | The hole | |---|---| | `cli/src/cmd-verify.ts:147` | **The `budgets` step skipped its per-route JS/LCP half entirely when `.x/build-stats.json` was absent — and `.x/` is gitignored.** So it has never run, in CI or on either gated app, and reported green throughout. `bunx create-ultimate myapp && x verify` gives every generated route a `budget: {js:'60kb', lcp:2500}` and weighs none of them. `budgets.ts`' own docstring: "A declared budget with no measurement is a finding, never a pass … exactly the false green axiom 5 exists to prevent." An absent stats file is now `X_BUDGET_UNMEASURED` per budgeted route. **Both gated apps go red as a result**, so `budgets` is pinned in `scripts/lib/gated-apps.ts` for each, naming the `x build`-before-the-gate work that closes it — the honest outcome, rather than restoring the silent pass. | | `scripts/boundaries.ts:44` | **A relative cross-package import was invisible to the tier check** — `scopedName()` only recognised `@ultimat3/…` specifiers. The repo already contained one, with a comment describing it as a deliberate evasion: `cli/src/serve.live.test.ts` imported `../../testing/src/sealed-network` precisely because the package specifier would be refused. Any package could bypass its tier with `../../<pkg>/src/x`. Relative specifiers now resolve back to a package before the tier check. | | `scripts/boundaries.ts:56` | **`Bun.Transpiler.scanImports` erases type-only imports, so a type-only upward import was not a build error** — contradicting CLAUDE.md's "Enforced by `bun run boundaries`; a violation is a build error". `packages/core` could `import type` from `packages/cli` and the check would report clean. Zero live instances, so this was latent; now caught by a second pass over the source with the `type` keyword rewritten (not a regex, so template literals and doc blocks are not false positives). | | `biome.json` | The `lint` step printed "biome: no any, **no default exports**, **no raw colours**" — and enforced neither. `noDefaultExport` is not in Biome's `recommended` and was never enabled; Biome ignores `.scss` entirely, so all 64 stylesheets under `packages/ui/src` were unlinted. `noDefaultExport` is now `error`, `noNonNullAssertion` is raised from `warn` to `error` (`biome check` exits 0 on warnings, so `foo!` was unenforced), and the step's summary now names only what is actually enforced. | | `ui/src/tokens/tokens.test.ts:88` | The only raw-colour enforcement in the repo checked **exactly three files**, none of them a component stylesheet — the 51 `.module.scss` files under `components/` were covered by neither this test nor Biome. Now globs every `.scss` under `packages/ui/src` except the canonical token files, matches `rgb(`/`hsl(` as well as hex, and asserts it found >50 files so an empty glob cannot pass. | | `x.verify.json` | The suite floor omitted `job` and `eval`, both of which apply at the repo root — so deleting those suites turned them into silent skips and the gate stayed green at "17/17 (1 skipped)". | | `cli/src/test-select.ts:19` | `TEST_GLOB` was `**/*.test.ts`, missing `.test.tsx` — a JSX test would be excluded from the gate's `unit`/`contract`/`job` steps while `bun run test` at the root still ran it. | | `cli/src/source-files.ts:5` | `packages/*/e2e/**` was outside both `SOURCE_GLOBS` and the boundary collector, so `filesize`, `errors` and `boundaries` never saw three real source directories. | | `scripts/boundaries.ts:194` | The `shared/` leaf rule globbed `examples/*` only, so the **deployed demo app** — the one CI publishes an image for on every push to main — was checked by nothing blocking. | | `scripts/roadmap.ts:44` | Milestone numbers came from a hardcoded map, so "every milestone row carries a status marker" only covered 0–11. Appending a milestone 12 with no marker passed. Now parses the table itself; a row with no artifacts entry is `X_ROADMAP_MILESTONE_UNTRACKED`. | | `scripts/release.ts:98` | `--bump` was cast to its union with **no validation**: `--bump majr` fell through to `1.2.1`, so a breaking change ships as a patch. `--version 1.2` wrote `"version": "1.2"` into all 29 manifests. `report()` was also called with `ok: true` unconditionally, so pre-existing skew findings exited 0. | | `cli/src/workspace-checks.ts:97` | **`X_RELEASE_VERSION_SKEW` compared packages only to each other, so it had no anchor.** Nine tags (`v1.3.0`…`v1.10.1`) have been cut against 29 packages all still stamped `1.2.0` — the gate is green while the tag lies, and a real publish would die `EPUBLISHCONFLICT` on all 29. `package-shape` gains a `--release <version>` mode; `bun run scripts/release.ts --check <version>` asserts the lockstep version equals the version being published. Verified live: `--check 1.2.0` passes, `--check 1.10.1` reports 141 findings and exits 1. **`.github/workflows/release.yml` still needs the call added before the publish loop — that file is outside this PR and is tracked separately.** | ## CLI correctness — the agent-facing surface | Where | Defect | |---|---| | `cli/src/dispatch.ts:51` | The parse-failure path read `argv.includes('--json')`, so **`-j` was ignored and errors rendered as prose on stdout**. `x doctor -j --bogusflag` and `x nonexistentcmd -j` both emit human text — exactly the two cases an agent hits while always passing `-j`, and `JSON.parse` throws on the result. | | `cli/src/templates/route.ts:25` | **`x g route "posts/[slug]"` silently scaffolded a static route.** Every segment went through `kebab()`, which strips `[` and `]`, so the agent got `apps/web/app/posts/slug/page.tsx` with exit 0 and no warning — and a generated test hard-coding `params: {}`. | | `cli/src/cmd-generate.ts:376` | A missing `<name>` was reported as `X_CLI_UNKNOWN_COMMAND` for a command form that *is* known, with `fix: x g route <name>` — which pasted into bash is a **redirect**. Now a missing-positional error with a concrete runnable example. Swept the same shape across `mcp-errors.ts` (14 entries), `errors.ts` (5) and `cmd-planned.ts`: any `<placeholder>` now sits behind a `#`, never in the runnable half. | | `cli/src/templates/scaffold-repo.ts:225` | **`x new` scaffolded two house-rule violations into every generated app**: a restated `Money` interface (CLAUDE.md: "one declaration in `@ultimat3/schema` … never restated") and a bare `RangeError`. Flagged independently by two auditors. Now re-exports `MoneyValue as Money` and throws a generated `UltimateError` subclass. | | `cli/src/cmd-doctor.ts:165` | `--port` was `parseInt`'d unvalidated, so **a bad value turned the port probe into a check that cannot fail** — `x doctor --port abc` reports the environment shippable while 3000 is occupied. Same at `cmd-dev.ts:268` (`NaN` to `Bun.serve` binds an arbitrary port) and `cmd-test.ts` (`--workers 4abc` accepted as 4, while `cmd-verify.ts`' comment claimed it was refused). One `readIntFlag` now serves all four. | | `cli/src/cmd-doctor.ts` | New `X_STORAGE_SECRET_DEV` finding mirroring the existing dev-cursor-secret check, wired to `usesDevStorageSecret()` from #80. | | `cli/src/dev-runtime.ts:150` | `startServices` falls back to the local disk driver whenever `S3_ENDPOINT`/`S3_BUCKET` are unset, which after #80 throws at boot in production. Made that failure an *instruction*: it leads with the storage choice ("no S3_ENDPOINT/S3_BUCKET, so this production process fell back to the embedded disk at …") and names object storage first. Deliberately **not** an outright ban on the local disk in production — a single-node Compose deploy on a mounted volume with a real secret is a legitimate rung on the scale ladder, and refusing it is a deploy-shape decision, not a security fix. | | `cli/src/templates/action.ts:93` | Every generated feature shipped `code: 'X_INVOICE_NOT_FOUND'` beside `docs: '…/errors/X_NOT_FOUND'` — following the link landed on a different code's page. | | `cli/src/cmd-generate.ts:400` | `--dry-run` reported `summary: "wrote 4 file(s)"` while `data.dryRun` was true. | | `cli/src/cmd-errors.ts:88` | `x errors` with no code reported a `--code` flag **that does not exist**; an agent reading the cause literally gets a second error. | | `scripts/new-package.ts:98` | Every scaffolded package documented "may import tiers 0-5" regardless of `--tier`, because the allowed range was derived from the tier table the new package is not yet in. `--tier abc` produced "Tier NaN". The file had no test; it has one now. | | `scripts/lib/tiers.ts:46` | `create-ultimate` resolved to the unlisted tier, so its declared `→ cli` edge restricted nothing — it could import all 28 packages. Now pinned above the table with that edge as its only permitted import. | | `scripts/lib/run.ts:18` | A bare `RangeError` at the scripts' single subprocess boundary, where `cli/src/exec.ts` does the identical guard correctly and explains why. | | `scripts/scaffold-smoke-overrides.ts` | Wrote prose to stdout, took no `--json`, and exited 1 with no code — and if it found no workspace manifests it wrote `{}`, silently making the smoke job install from **the npm registry** instead of the working tree. That is now a hard error. | | `create-ultimate/src/bin.ts:11` | The only published entry point using `process.stdout.write` + `process.exit`, the combination both `cli/src/bin.ts` and `scripts/lib/log.ts` carry comments explaining truncates at 64KB under a pipe. | | `ui/src/components/date-time-view.ts:42` | `toDate` fell back to `new Date(value)`, whose parse of an offset-less datetime uses the **host's** zone — an ambient default in the one package that forbids them. Every formatting path was correctly zoned; only the parse was not. | | `scripts/help.ts:21` | Claimed 16 verify steps against 17, and omitted the app gate — a headline command in CLAUDE.md — from the catalogue an agent reads to discover the repo. | ## Not closed, and named An undriven `e2eTest` still reports **green** rather than skipped. The filename half is fixed (the generated assertion now lands in `page.e2e.test.ts`, which the `e2e` step actually selects on) and `hasE2eDriver()` is exported so the seam has one name — but the driver registers inside the `bun test` child and the step's only channel is an exit code, which is 0 on skips. Making it red would turn a scaffolded app's `e2e` step red on `x g route` output, and that blast radius could not be proven here. `test-types.ts`' docstring no longer claims behaviour nothing implements. ## New error codes `X_STORAGE_SECRET_DEV`, `X_ROADMAP_MILESTONE_UNTRACKED`, `X_SCAFFOLD_OVERRIDES_EMPTY` — documented, registered, in the manifest. `X_BUDGET_UNMEASURED` already existed and was already documented; only the code path that emits it was missing. ## Behaviour changes `x doctor --port` / `x dev --port` / `x test --workers` now **refuse** bad values with `X_CLI_BAD_FLAG` instead of coercing them. Same surface, stricter contract; `wiki/Error-Codes.md`'s row for that code is widened to name positionals. ## Gate `bun run verify` green on this branch: 14/17, same three structural skips as `main`. `bunx biome check .` clean across 3547 files with both new rules at `error`.

…cursor duplication Tier 2 of a four-PR audit sweep. Every finding was reproduced by running the code before it was fixed, and every fix ships a test verified to go red on the old code by reverting the source change and watching it fail. Companion to #80 (tier 0–1). Independent of it — green on `main` alone. ## Security | Where | Defect | |---|---| | `auth/src/verify.ts:118` | **`consumeVerification` consumed the verification row *before* comparing the token hash.** An unauthenticated attacker POSTs the reset endpoint with `{identifier:'victim@example.com', token:'x'}` → the row is marked `consumed_at = now()`, the comparison then fails and throws — and the victim's emailed link is dead. Run it on a loop and password reset is permanently denied for any address you know. The hash is now an argument to the consume (`takeVerification(purpose, identifier, tokenHash)`), so both adapters consume **only on a match** and a wrong guess leaves the row live. | | `http/src/auth-redirect.ts:56` | **Open redirect.** `nextAfterSignIn` rejected `//` and `/\` but not a control character the URL parser strips: `nextAfterSignIn('%2F%09%2Fevil.test', '/')` returned `"/\t/evil.test"`, and browsers remove TAB/CR/LF from a `Location` before parsing → `//evil.test` → `https://evil.test`. Exactly the phishing shape the comment above it claims to prevent. Now rejects `\t\r\n`, re-parses against a sentinel origin and requires the origin unchanged, and no longer throws a bare `URIError` on `?next=%`. | | `http/src/request.ts:164` | **Unbounded body allocation.** The size cap was checked *after* the whole body was materialised, and the pre-check only fired when `content-length` was present. A `Transfer-Encoding: chunked` POST with a 10 GB body allocated 10 GB before `byteLength > limit` was ever evaluated — OOM instead of a 413. `multipart/form-data` had no byte guard at all when the length was undeclared. Bodies now stream through a counting reader that cancels the moment the running total passes the limit. | | `http/src/pipeline.ts:160` | **Personalised HTML leaked to shared caches.** Every response on an `auth:'public'` route was marked `public, max-age=0, s-maxage=60, stale-while-revalidate=600`, and only `Vary: accept-language` was added — never `Vary: cookie`. `RouteMeta.auth` is only `'public' | 'required'`, so the very common "public page that greets you if signed in" route handed a signed-in user's HTML to a shared CDN for 60s, which then served it to everyone else. Now: a non-anonymous actor gets `private`, **and** the anonymous shared-cacheable default carries `cookie` in its `vary`. Both halves — either alone leaves a hole. | ## Correctness | Where | Defect | |---|---| | `entity/src/cursor.ts:73` | **Keyset pagination returned the same row twice.** The cursor serialised timestamps with `toISOString()` (millisecond precision) while the column is bare `timestamptz` — `now()` gives microseconds. With `createdAt = …:00.123456Z` as the last row of page 1, the cursor carried `…123Z` and page 2 emitted `created_at > '…123'`, which that same row satisfies. It came back on **every page boundary**, and the `id` tiebreak did not help because the first `or` term already matched. Fixed entity-side: a timestamp seek now compares against the millisecond *window* as a half-open range, so the column stays bare and the index still range-scans. | | `auth/src/builtin-adapter.ts:248` | The Postgres `takeVerification` had no `LIMIT` and no ordering while `one()` returns `rows[0]`, so it consumed **every** live row and returned an arbitrary one. Latent rather than reachable — the shipped DDL carries `unique (purpose, identifier)` — but a table without that constraint would have silently rejected the correct token about half the time. Now one statement, scoped to one row, with `consumed_at is null` on both the outer update and the subselect so two racing redemptions cannot both consume. | | `http/src/cors.ts:25` | `origins: ['*']` with the default `credentials: true` returned `null` and emitted **no CORS headers at all**, silently. The natural "open it up" edit produced total CORS failure and a browser console full of unexplained blocks; the type comment said `'*'` is allowed only when `credentials` is false, and nothing enforced it. Now refused at config time with `X_CORS_CONFIG_INVALID`, whose `fix:` names the one-line `app.config.ts` edit. | | `http/src/cors.ts:34` | A refused origin returned `{}` with no `Vary: origin`, so a shared CDN stored the un-CORS'd response under the URL alone and then served it to an allowed origin — intermittent, unreproducible-looking CORS breakage. `vary: origin` is now always emitted, refusal path included. Fixing this surfaced a pre-existing clobber: CORS's `vary` was overwriting the cache stage's key on every allowed cross-origin response, so the response stage now merges `vary` instead of setting it. | | `http/src/security-headers.ts:112` | The comment says "HSTS over plaintext is ignored by browsers and confuses local dev, so skip it", but the guard was `options.https !== false` — so the zero-argument default **emitted** `max-age=63072000; includeSubDomains`. Only the pipeline, which passes `ctx.https` explicitly, got the documented behaviour; every other caller got the opposite. The code now matches its comment. | | `http/src/locale.ts:37` | Unguarded `decodeURIComponent` in the `locale` stage, which runs on every request: `Cookie: x-locale=%` threw a non-`UltimateError`, mapped to a 500, and paged the on-call. `auth/src/session.ts` already guards this exact case; the guard is duplicated locally rather than imported, because `http → auth` is a forbidden sideways edge — with a comment saying so. | ## Test seam for the reference app (issue #9) `entity/src/database.ts` kept a module-level `let shared: Driver | undefined` and `repo.ts` offered no way to clear it, so a test preload could not seed the driver the app reads from. That is the root cause of three of the four failing reference-app suites. This PR adds the minimal seam and nothing more: `defaultDriver()` is exported, `Driver.reset?()` is optional and implemented by `memoryDriver()` only (the Postgres driver leaves it undefined), and `memoryRepo()` clears **in place** so a repo a table already resolved is the one that empties. The fixture work itself is a later PR. ## New error code `X_CORS_CONFIG_INVALID` — documented in `wiki/Error-Codes.md`, registered, mapped to a status, in the manifest. ## Semver — needs a decision before the next release `VerificationStore.takeVerification` gained a required third parameter. That is a breaking change to the documented `AuthAdapter` seam, so it cannot ship in a 1.x. No caller exists outside `packages/auth/src` (grepped repo-wide, apps included), so the blast radius today is zero — but the alternative (an optional parameter) reintroduces the vulnerability for any adapter that ignores it, which is why it was not taken. ## Gate `bun run verify` green on this branch alone: 14/17, with the same three structural skips as `main` (`drift`, `contract-diff`, `budgets`).

Now refused at config time with `X_CORS_CONFIG_INVALID`, whose `fix:` names the one-line `app.config.ts` edit. | | `http/src/cors.ts:34` | A refused origin returned `{}` with no `Vary: origin`, so a shared CDN stored the un-CORS'd response under the URL alone and then served it to an allowed origin — intermittent, unreproducible-looking CORS breakage. `vary: origin` is now always emitted, refusal path included. Fixing this surfaced a pre-existing clobber: CORS's `vary` was overwriting the cache stage's key on every allowed cross-origin response, so the response stage now merges `vary` instead of setting it. | | `http/src/security-headers.ts:112` | The comment says "HSTS over plaintext is ignored by browsers and confuses local dev, so skip it", but the guard was `options.https !== false` — so the zero-argument default **emitted** `max-age=63072000; includeSubDomains`. Only the pipeline, which passes `ctx.https` explicitly, got the documented behaviour; every other caller got the opposite. The code now matches its comment. | | `http/src/locale.ts:37` | Unguarded `decodeURIComponent` in the `locale` stage, which runs on every request: `Cookie: x-locale=%` threw a non-`UltimateError`, mapped to a 500, and paged the on-call. `auth/src/session.ts` already guards this exact case; the guard is duplicated locally rather than imported, because `http → auth` is a forbidden sideways edge — with a comment saying so. | ## Test seam for the reference app (issue #9) `entity/src/database.ts` kept a module-level `let shared: Driver | undefined` and `repo.ts` offered no way to clear it, so a test preload could not seed the driver the app reads from. That is the root cause of three of the four failing reference-app suites. This PR adds the minimal seam and nothing more: `defaultDriver()` is exported, `Driver.reset?()` is optional and implemented by `memoryDriver()` only (the Postgres driver leaves it undefined), and `memoryRepo()` clears **in place** so a repo a table already resolved is the one that empties. The fixture work itself is a later PR. ## New error code `X_CORS_CONFIG_INVALID` — documented in `wiki/Error-Codes.md`, registered, mapped to a status, in the manifest. ## Semver — needs a decision before the next release `VerificationStore.takeVerification` gained a required third parameter. That is a breaking change to the documented `AuthAdapter` seam, so it cannot ship in a 1.x. No caller exists outside `packages/auth/src` (grepped repo-wide, apps included), so the blast radius today is zero — but the alternative (an optional parameter) reintroduces the vulnerability for any adapter that ignores it, which is why it was not taken. ## Gate `bun run verify` green on this branch alone: 14/17, with the same three structural skips as `main` (`drift`, `contract-diff`, `budgets`).

…, run-once fired 24 times Tiers 3–4 of a four-PR audit sweep. Every finding was reproduced by running the code before it was fixed, and every fix ships a test verified failure-first by reverting the source change and watching it go red. **Stacked on #80** — the read cache now uses `@ultimat3/cache`'s `LruCache` and its TTL rule, so this needs the tier-1 change beneath it. ## The invalidation that never invalidated `query/src/cache.ts:50` — **the default read-cache tier was never registered with `@ultimat3/cache`, so `invalidateQueryTags()` — and therefore every action's `cache.invalidates` — evicted nothing.** With no `ttlMs` the entry was immortal. Measured: `readThrough` → `1`; `invalidateQueryTags([tag('post')])`; `registeredTiers()` is `[]`; second `readThrough` → still `1`, entry `{value:1, expiresAt:null}`. In an app: create a post, read the list, publish through an action declaring `cache: { invalidates: [tag.post] }`, read again — **the pre-publish list is served for the life of the process.** `setReadCache` was exported and called from nowhere in the repo, and `cache.test.ts` had no invalidation test. The module header claimed "Invalidation is never local — it goes through @ultimat3/cache so an action's `invalidates` and a query's `tags` meet in one graph." That is now true. The tier is also bounded (32 MiB LRU) and defaults a 60s TTL, where it was previously an unbounded map of immortal entries keyed on every distinct input — a paginated feed over 10k orgs wrote 10k+ permanent, unevictable entries per process. ## Other correctness | Where | Defect | |---|---| | `pwa/src/service-worker.ts:211` | **Every precached byte was a permanent miss.** Entries were written under `url + '?v=' + revision`, but every strategy read `caches.match(req)` on the bare URL with the default `ignoreSearch:false`. Offline, a route with `offline:'precache'` missed its own precache and fell through to the offline document; online, every precached asset was downloaded twice. Entries are now re-keyed onto the bare URL after `addAll` fetches them revision-addressed, preserving its all-or-nothing failure. The new test *executes* the emitted `sw.js` against stub `caches`/`fetch`. | | `jobs/src/scheduler.ts:206` | **`catchUp: 'run-once'` fired once per tick until every missed occurrence drained.** Measured: an hourly task with the scheduler down 24h produced **24 dispatches**, not one — a nightly digest becomes 24 digests a second apart. `task.ts:23` documents the opposite and no test asserted it. Note the fix marks the watermark at `at`, not at `due[last]` as first proposed: `maxCatchUp` truncates `due` to 10, so `due[last]` would still have fired three times. | | `ai/src/llm.ts:208` | The repair turn appended `{role:'assistant', content: result.text}` — the **empty string** whenever the model answered through the `respond` tool, which is the dominant path. The Messages API rejects an empty text block, so a schema-invalid response produced `X_AI_PROVIDER_UNAVAILABLE` from a 400 instead of the repair it was trying to do, and the `tool_use` block was dropped from the replayed history. | | `ai/src/budget.ts:125` | `reserve()` checked the ceiling but **debited nothing** — only `record()` did — so concurrent calls under one ledger all passed the same check. Three parallel `summarize` calls estimating 4k tokens each all read `spent() === 0`, all passed, and recorded 12k against a 10k ceiling. The "un-bypassable" org budget was bypassable by parallelism. `reserve()` now debits and returns a reservation that `record()` reconciles and `release()` returns; reservations serialise on a turnstile because check-then-debit spans an `await`. | | `realtime/src/live-query.ts:388` | **`sid` was client-supplied and unvalidated.** Socket B could reuse socket A's `sid`: `#bySid[S]` then pointed at B while A's subscription stayed in the entry's subscriber set, so A's disconnect freed nothing — the entry, its matcher and its shared window leaked permanently and every subsequent change fanned out to a dead socket. A `{op:'drop', sid:S}` from B also killed A's live stream, with no error on either side. Subscriptions are now keyed by `(socketId, sid)`, and a sid the same socket already holds is refused. | | `jobs/src/outbox.ts:285` | The relay's interval body was `void tick().finally(...)` with **no `.catch`** — a rejection from `store.claim()` is an unhandled rejection, and Bun's default terminates the process. One connection-pool timeout during a failover killed the worker with staged, unpublished jobs. Every other loop in the package already used `.catch(...)` first. | | `jobs/src/outbox.ts:55` | The memory store never removed published rows, so `claim()` and `pendingCount()` walked every row ever enqueued on each 200ms tick and no payload was ever freed. | | `jobs/src/steps.ts:173` | `claimName` was an O(n) `Array.includes` over every step name in the attempt — a `backfill()` over 1M rows at batch 50 is 20,000 steps, so ~200M string comparisons plus a 20k-entry array carried into `x jobs show`. | | `action/src/naming.ts:59` | Two distinct actions could derive **one** HTTP path with nothing refusing it — `archiveOrder` and `archiveOrders` both derive `POST /api/orders/archive`. `X_ACTION_DUPLICATE` only guards names, so both registered and whichever the router seated last silently shadowed the other, while the shadowed action's OpenAPI operation and MCP tool kept advertising it. Now `X_ACTION_PATH_DUPLICATE`. | | `render/src/render-stream.ts:81` | A client disconnecting mid-stream produced one unhandled rejection per late hole and left every hole running with nowhere to write. The source gained `cancel()` to abort the holes, and writes are guarded on a closed controller. | | `render/src/render-isr.ts:224` | `attach()`'s returned detach unregistered dependents but never cleared the revalidator it installed, so a hot reload left the old controller receiving revalidations — the new one's pages never went stale and the old store was never collected. | | `render/src/render-isr.ts:41` | The default ISR store was an unbounded map keyed by rendered path on a route table supporting `:params` — a crawler hitting 100k slugs held 100k HTML strings for the process's lifetime. Now LRU-capped. | | `realtime/src/client.ts:153` | `connect()` replaced `#socket` without closing the previous one, so the orphan's frame handler kept mutating live registrations — patches applied twice and the server held two sockets per client until the tab closed. | | `mcp/src/transport-http.ts:75` | The body was parsed **before** the token was resolved, contradicting the stated "401 before parsing" property: an invalid token got `400 parse error` for malformed JSON and `401` for well-formed, which is exactly the oracle the comment says the 401 exists to remove. | | `ai/src/models.ts:12` | `LlmRefusedError`'s alternative was `MODEL_IDS.find(id => id !== result.model)` — the first id that differs — so a refusal on the most capable model suggested retrying on a **weaker** one. Now walks the capability ladder upward and drops the suggestion when there is no rung above. | | `ai/src/models.ts:133` | `reasoningBody` always emitted `thinking: {type:'adaptive'}` for any adaptive-capable model, including when the declaration asked for neither — while the comment two lines above claims "a control the caller never asked for is OMITTED rather than defaulted". Harmless (adaptive is the server default), but the stated invariant was not the code's. | | `jobs/src/backfill-pass-fixture.ts:146` | A bare `Error` in shipped `src/`. Now a named class, and `"!src/**/*-fixture.ts"` keeps test material out of the tarball. | ## Dropped — the audit was wrong The sweep flagged the manifest as omitting `mutator: true`. It does not: the brand survives registration, `describeAction` reads it, `sources.ts` emits it, `build.ts` carries it through, and `examples/dummy/x.manifest.json` **already carries `"mutator": true`** on all three mutators. No top-level `mutators` key exists, but that is by design — a mutator *is* an action on the same authz path, and a second list would be the same objects twice. No change made. ## Not done, and why `claude-fable-5` was **not** added to the model catalogue. Its pricing and limits are verifiable, but it can never disable thinking, which `ModelReasoning.disableThinkingUpTo: undefined` currently reads as "every effort may disable" — expressing it needs a shape change plus decisions about retention and refusal classifiers. The underlying bug (suggesting a downgrade) is fixed by capability rank instead, which is the safer half. Rather than invent a capability row, this is left named. `skip`-mode catch-up has the same `maxCatchUp` truncation shape and was left alone as out of scope: after a >10-occurrence outage it fires occurrence 10, then 20, then 24 — three dispatches, two of them stale. Worth its own finding. ## New error codes `X_ACTION_PATH_DUPLICATE`, `X_SUBSCRIPTION_ID_TAKEN` — both documented in `wiki/Error-Codes.md`, registered, in the manifest. ## Semver — needs a decision before the next release `LiveQueryRegistry.unsubscribe` and `.subscription` gained a `socketId` parameter. Breaking on an exported class; no in-repo caller outside realtime's own tests. Also: a `cache:` query with no `ttlMs` now expires at 60s where it previously never did. ## Gate `bun run verify` green on this branch: 14/17, same three structural skips as `main`.

…face agents actually hit Tier 5 and the build tooling — the last of a four-PR audit sweep, and the one that matters most: **several findings are holes in `bun run verify` itself.** A gate step that silently passes is worse than no step, because it is read as coverage. **Stacked on #80** — the doctor check consumes a storage export from it, and `noNonNullAssertion` could only be raised once its `ids.ts` fix landed. ## Gate holes closed | Where | The hole | |---|---| | `cli/src/cmd-verify.ts:147` | **The `budgets` step skipped its per-route JS/LCP half entirely when `.x/build-stats.json` was absent — and `.x/` is gitignored.** So it has never run, in CI or on either gated app, and reported green throughout. `bunx create-ultimate myapp && x verify` gives every generated route a `budget: {js:'60kb', lcp:2500}` and weighs none of them. `budgets.ts`' own docstring: "A declared budget with no measurement is a finding, never a pass … exactly the false green axiom 5 exists to prevent." An absent stats file is now `X_BUDGET_UNMEASURED` per budgeted route. **Both gated apps go red as a result**, so `budgets` is pinned in `scripts/lib/gated-apps.ts` for each, naming the `x build`-before-the-gate work that closes it — the honest outcome, rather than restoring the silent pass. | | `scripts/boundaries.ts:44` | **A relative cross-package import was invisible to the tier check** — `scopedName()` only recognised `@ultimat3/…` specifiers. The repo already contained one, with a comment describing it as a deliberate evasion: `cli/src/serve.live.test.ts` imported `../../testing/src/sealed-network` precisely because the package specifier would be refused. Any package could bypass its tier with `../../<pkg>/src/x`. Relative specifiers now resolve back to a package before the tier check. | | `scripts/boundaries.ts:56` | **`Bun.Transpiler.scanImports` erases type-only imports, so a type-only upward import was not a build error** — contradicting CLAUDE.md's "Enforced by `bun run boundaries`; a violation is a build error". `packages/core` could `import type` from `packages/cli` and the check would report clean. Zero live instances, so this was latent; now caught by a second pass over the source with the `type` keyword rewritten (not a regex, so template literals and doc blocks are not false positives). | | `biome.json` | The `lint` step printed "biome: no any, **no default exports**, **no raw colours**" — and enforced neither. `noDefaultExport` is not in Biome's `recommended` and was never enabled; Biome ignores `.scss` entirely, so all 64 stylesheets under `packages/ui/src` were unlinted. `noDefaultExport` is now `error`, `noNonNullAssertion` is raised from `warn` to `error` (`biome check` exits 0 on warnings, so `foo!` was unenforced), and the step's summary now names only what is actually enforced. | | `ui/src/tokens/tokens.test.ts:88` | The only raw-colour enforcement in the repo checked **exactly three files**, none of them a component stylesheet — the 51 `.module.scss` files under `components/` were covered by neither this test nor Biome. Now globs every `.scss` under `packages/ui/src` except the canonical token files, matches `rgb(`/`hsl(` as well as hex, and asserts it found >50 files so an empty glob cannot pass. | | `x.verify.json` | The suite floor omitted `job` and `eval`, both of which apply at the repo root — so deleting those suites turned them into silent skips and the gate stayed green at "17/17 (1 skipped)". | | `cli/src/test-select.ts:19` | `TEST_GLOB` was `**/*.test.ts`, missing `.test.tsx` — a JSX test would be excluded from the gate's `unit`/`contract`/`job` steps while `bun run test` at the root still ran it. | | `cli/src/source-files.ts:5` | `packages/*/e2e/**` was outside both `SOURCE_GLOBS` and the boundary collector, so `filesize`, `errors` and `boundaries` never saw three real source directories. | | `scripts/boundaries.ts:194` | The `shared/` leaf rule globbed `examples/*` only, so the **deployed demo app** — the one CI publishes an image for on every push to main — was checked by nothing blocking. | | `scripts/roadmap.ts:44` | Milestone numbers came from a hardcoded map, so "every milestone row carries a status marker" only covered 0–11. Appending a milestone 12 with no marker passed. Now parses the table itself; a row with no artifacts entry is `X_ROADMAP_MILESTONE_UNTRACKED`. | | `scripts/release.ts:98` | `--bump` was cast to its union with **no validation**: `--bump majr` fell through to `1.2.1`, so a breaking change ships as a patch. `--version 1.2` wrote `"version": "1.2"` into all 29 manifests. `report()` was also called with `ok: true` unconditionally, so pre-existing skew findings exited 0. | | `cli/src/workspace-checks.ts:97` | **`X_RELEASE_VERSION_SKEW` compared packages only to each other, so it had no anchor.** Nine tags (`v1.3.0`…`v1.10.1`) have been cut against 29 packages all still stamped `1.2.0` — the gate is green while the tag lies, and a real publish would die `EPUBLISHCONFLICT` on all 29. `package-shape` gains a `--release <version>` mode; `bun run scripts/release.ts --check <version>` asserts the lockstep version equals the version being published. Verified live: `--check 1.2.0` passes, `--check 1.10.1` reports 141 findings and exits 1. **`.github/workflows/release.yml` still needs the call added before the publish loop — that file is outside this PR and is tracked separately.** | ## CLI correctness — the agent-facing surface | Where | Defect | |---|---| | `cli/src/dispatch.ts:51` | The parse-failure path read `argv.includes('--json')`, so **`-j` was ignored and errors rendered as prose on stdout**. `x doctor -j --bogusflag` and `x nonexistentcmd -j` both emit human text — exactly the two cases an agent hits while always passing `-j`, and `JSON.parse` throws on the result. | | `cli/src/templates/route.ts:25` | **`x g route "posts/[slug]"` silently scaffolded a static route.** Every segment went through `kebab()`, which strips `[` and `]`, so the agent got `apps/web/app/posts/slug/page.tsx` with exit 0 and no warning — and a generated test hard-coding `params: {}`. | | `cli/src/cmd-generate.ts:376` | A missing `<name>` was reported as `X_CLI_UNKNOWN_COMMAND` for a command form that *is* known, with `fix: x g route <name>` — which pasted into bash is a **redirect**. Now a missing-positional error with a concrete runnable example. Swept the same shape across `mcp-errors.ts` (14 entries), `errors.ts` (5) and `cmd-planned.ts`: any `<placeholder>` now sits behind a `#`, never in the runnable half. | | `cli/src/templates/scaffold-repo.ts:225` | **`x new` scaffolded two house-rule violations into every generated app**: a restated `Money` interface (CLAUDE.md: "one declaration in `@ultimat3/schema` … never restated") and a bare `RangeError`. Flagged independently by two auditors. Now re-exports `MoneyValue as Money` and throws a generated `UltimateError` subclass. | | `cli/src/cmd-doctor.ts:165` | `--port` was `parseInt`'d unvalidated, so **a bad value turned the port probe into a check that cannot fail** — `x doctor --port abc` reports the environment shippable while 3000 is occupied. Same at `cmd-dev.ts:268` (`NaN` to `Bun.serve` binds an arbitrary port) and `cmd-test.ts` (`--workers 4abc` accepted as 4, while `cmd-verify.ts`' comment claimed it was refused). One `readIntFlag` now serves all four. | | `cli/src/cmd-doctor.ts` | New `X_STORAGE_SECRET_DEV` finding mirroring the existing dev-cursor-secret check, wired to `usesDevStorageSecret()` from #80. | | `cli/src/dev-runtime.ts:150` | `startServices` falls back to the local disk driver whenever `S3_ENDPOINT`/`S3_BUCKET` are unset, which after #80 throws at boot in production. Made that failure an *instruction*: it leads with the storage choice ("no S3_ENDPOINT/S3_BUCKET, so this production process fell back to the embedded disk at …") and names object storage first. Deliberately **not** an outright ban on the local disk in production — a single-node Compose deploy on a mounted volume with a real secret is a legitimate rung on the scale ladder, and refusing it is a deploy-shape decision, not a security fix. | | `cli/src/templates/action.ts:93` | Every generated feature shipped `code: 'X_INVOICE_NOT_FOUND'` beside `docs: '…/errors/X_NOT_FOUND'` — following the link landed on a different code's page. | | `cli/src/cmd-generate.ts:400` | `--dry-run` reported `summary: "wrote 4 file(s)"` while `data.dryRun` was true. | | `cli/src/cmd-errors.ts:88` | `x errors` with no code reported a `--code` flag **that does not exist**; an agent reading the cause literally gets a second error. | | `scripts/new-package.ts:98` | Every scaffolded package documented "may import tiers 0-5" regardless of `--tier`, because the allowed range was derived from the tier table the new package is not yet in. `--tier abc` produced "Tier NaN". The file had no test; it has one now. | | `scripts/lib/tiers.ts:46` | `create-ultimate` resolved to the unlisted tier, so its declared `→ cli` edge restricted nothing — it could import all 28 packages. Now pinned above the table with that edge as its only permitted import. | | `scripts/lib/run.ts:18` | A bare `RangeError` at the scripts' single subprocess boundary, where `cli/src/exec.ts` does the identical guard correctly and explains why. | | `scripts/scaffold-smoke-overrides.ts` | Wrote prose to stdout, took no `--json`, and exited 1 with no code — and if it found no workspace manifests it wrote `{}`, silently making the smoke job install from **the npm registry** instead of the working tree. That is now a hard error. | | `create-ultimate/src/bin.ts:11` | The only published entry point using `process.stdout.write` + `process.exit`, the combination both `cli/src/bin.ts` and `scripts/lib/log.ts` carry comments explaining truncates at 64KB under a pipe. | | `ui/src/components/date-time-view.ts:42` | `toDate` fell back to `new Date(value)`, whose parse of an offset-less datetime uses the **host's** zone — an ambient default in the one package that forbids them. Every formatting path was correctly zoned; only the parse was not. | | `scripts/help.ts:21` | Claimed 16 verify steps against 17, and omitted the app gate — a headline command in CLAUDE.md — from the catalogue an agent reads to discover the repo. | ## Not closed, and named An undriven `e2eTest` still reports **green** rather than skipped. The filename half is fixed (the generated assertion now lands in `page.e2e.test.ts`, which the `e2e` step actually selects on) and `hasE2eDriver()` is exported so the seam has one name — but the driver registers inside the `bun test` child and the step's only channel is an exit code, which is 0 on skips. Making it red would turn a scaffolded app's `e2e` step red on `x g route` output, and that blast radius could not be proven here. `test-types.ts`' docstring no longer claims behaviour nothing implements. ## New error codes `X_STORAGE_SECRET_DEV`, `X_ROADMAP_MILESTONE_UNTRACKED`, `X_SCAFFOLD_OVERRIDES_EMPTY` — documented, registered, in the manifest. `X_BUDGET_UNMEASURED` already existed and was already documented; only the code path that emits it was missing. ## Behaviour changes `x doctor --port` / `x dev --port` / `x test --workers` now **refuse** bad values with `X_CLI_BAD_FLAG` instead of coercing them. Same surface, stricter contract; `wiki/Error-Codes.md`'s row for that code is widened to name positionals. ## Gate `bun run verify` green on this branch: 14/17, same three structural skips as `main`. `bunx biome check .` clean across 3547 files with both new rules at `error`.

…face agents actually hit (#83) Tier 5 and the build tooling — the last of a four-PR audit sweep, and the one that matters most: **several findings are holes in `bun run verify` itself.** A gate step that silently passes is worse than no step, because it is read as coverage. **Stacked on #80** — the doctor check consumes a storage export from it, and `noNonNullAssertion` could only be raised once its `ids.ts` fix landed. ## Gate holes closed | Where | The hole | |---|---| | `cli/src/cmd-verify.ts:147` | **The `budgets` step skipped its per-route JS/LCP half entirely when `.x/build-stats.json` was absent — and `.x/` is gitignored.** So it has never run, in CI or on either gated app, and reported green throughout. `bunx create-ultimate myapp && x verify` gives every generated route a `budget: {js:'60kb', lcp:2500}` and weighs none of them. `budgets.ts`' own docstring: "A declared budget with no measurement is a finding, never a pass … exactly the false green axiom 5 exists to prevent." An absent stats file is now `X_BUDGET_UNMEASURED` per budgeted route. **Both gated apps go red as a result**, so `budgets` is pinned in `scripts/lib/gated-apps.ts` for each, naming the `x build`-before-the-gate work that closes it — the honest outcome, rather than restoring the silent pass. | | `scripts/boundaries.ts:44` | **A relative cross-package import was invisible to the tier check** — `scopedName()` only recognised `@ultimat3/…` specifiers. The repo already contained one, with a comment describing it as a deliberate evasion: `cli/src/serve.live.test.ts` imported `../../testing/src/sealed-network` precisely because the package specifier would be refused. Any package could bypass its tier with `../../<pkg>/src/x`. Relative specifiers now resolve back to a package before the tier check. | | `scripts/boundaries.ts:56` | **`Bun.Transpiler.scanImports` erases type-only imports, so a type-only upward import was not a build error** — contradicting CLAUDE.md's "Enforced by `bun run boundaries`; a violation is a build error". `packages/core` could `import type` from `packages/cli` and the check would report clean. Zero live instances, so this was latent; now caught by a second pass over the source with the `type` keyword rewritten (not a regex, so template literals and doc blocks are not false positives). | | `biome.json` | The `lint` step printed "biome: no any, **no default exports**, **no raw colours**" — and enforced neither. `noDefaultExport` is not in Biome's `recommended` and was never enabled; Biome ignores `.scss` entirely, so all 64 stylesheets under `packages/ui/src` were unlinted. `noDefaultExport` is now `error`, `noNonNullAssertion` is raised from `warn` to `error` (`biome check` exits 0 on warnings, so `foo!` was unenforced), and the step's summary now names only what is actually enforced. | | `ui/src/tokens/tokens.test.ts:88` | The only raw-colour enforcement in the repo checked **exactly three files**, none of them a component stylesheet — the 51 `.module.scss` files under `components/` were covered by neither this test nor Biome. Now globs every `.scss` under `packages/ui/src` except the canonical token files, matches `rgb(`/`hsl(` as well as hex, and asserts it found >50 files so an empty glob cannot pass. | | `x.verify.json` | The suite floor omitted `job` and `eval`, both of which apply at the repo root — so deleting those suites turned them into silent skips and the gate stayed green at "17/17 (1 skipped)". | | `cli/src/test-select.ts:19` | `TEST_GLOB` was `**/*.test.ts`, missing `.test.tsx` — a JSX test would be excluded from the gate's `unit`/`contract`/`job` steps while `bun run test` at the root still ran it. | | `cli/src/source-files.ts:5` | `packages/*/e2e/**` was outside both `SOURCE_GLOBS` and the boundary collector, so `filesize`, `errors` and `boundaries` never saw three real source directories. | | `scripts/boundaries.ts:194` | The `shared/` leaf rule globbed `examples/*` only, so the **deployed demo app** — the one CI publishes an image for on every push to main — was checked by nothing blocking. | | `scripts/roadmap.ts:44` | Milestone numbers came from a hardcoded map, so "every milestone row carries a status marker" only covered 0–11. Appending a milestone 12 with no marker passed. Now parses the table itself; a row with no artifacts entry is `X_ROADMAP_MILESTONE_UNTRACKED`. | | `scripts/release.ts:98` | `--bump` was cast to its union with **no validation**: `--bump majr` fell through to `1.2.1`, so a breaking change ships as a patch. `--version 1.2` wrote `"version": "1.2"` into all 29 manifests. `report()` was also called with `ok: true` unconditionally, so pre-existing skew findings exited 0. | | `cli/src/workspace-checks.ts:97` | **`X_RELEASE_VERSION_SKEW` compared packages only to each other, so it had no anchor.** Nine tags (`v1.3.0`…`v1.10.1`) have been cut against 29 packages all still stamped `1.2.0` — the gate is green while the tag lies, and a real publish would die `EPUBLISHCONFLICT` on all 29. `package-shape` gains a `--release <version>` mode; `bun run scripts/release.ts --check <version>` asserts the lockstep version equals the version being published. Verified live: `--check 1.2.0` passes, `--check 1.10.1` reports 141 findings and exits 1. **`.github/workflows/release.yml` still needs the call added before the publish loop — that file is outside this PR and is tracked separately.** | ## CLI correctness — the agent-facing surface | Where | Defect | |---|---| | `cli/src/dispatch.ts:51` | The parse-failure path read `argv.includes('--json')`, so **`-j` was ignored and errors rendered as prose on stdout**. `x doctor -j --bogusflag` and `x nonexistentcmd -j` both emit human text — exactly the two cases an agent hits while always passing `-j`, and `JSON.parse` throws on the result. | | `cli/src/templates/route.ts:25` | **`x g route "posts/[slug]"` silently scaffolded a static route.** Every segment went through `kebab()`, which strips `[` and `]`, so the agent got `apps/web/app/posts/slug/page.tsx` with exit 0 and no warning — and a generated test hard-coding `params: {}`. | | `cli/src/cmd-generate.ts:376` | A missing `<name>` was reported as `X_CLI_UNKNOWN_COMMAND` for a command form that *is* known, with `fix: x g route <name>` — which pasted into bash is a **redirect**. Now a missing-positional error with a concrete runnable example. Swept the same shape across `mcp-errors.ts` (14 entries), `errors.ts` (5) and `cmd-planned.ts`: any `<placeholder>` now sits behind a `#`, never in the runnable half. | | `cli/src/templates/scaffold-repo.ts:225` | **`x new` scaffolded two house-rule violations into every generated app**: a restated `Money` interface (CLAUDE.md: "one declaration in `@ultimat3/schema` … never restated") and a bare `RangeError`. Flagged independently by two auditors. Now re-exports `MoneyValue as Money` and throws a generated `UltimateError` subclass. | | `cli/src/cmd-doctor.ts:165` | `--port` was `parseInt`'d unvalidated, so **a bad value turned the port probe into a check that cannot fail** — `x doctor --port abc` reports the environment shippable while 3000 is occupied. Same at `cmd-dev.ts:268` (`NaN` to `Bun.serve` binds an arbitrary port) and `cmd-test.ts` (`--workers 4abc` accepted as 4, while `cmd-verify.ts`' comment claimed it was refused). One `readIntFlag` now serves all four. | | `cli/src/cmd-doctor.ts` | New `X_STORAGE_SECRET_DEV` finding mirroring the existing dev-cursor-secret check, wired to `usesDevStorageSecret()` from #80. | | `cli/src/dev-runtime.ts:150` | `startServices` falls back to the local disk driver whenever `S3_ENDPOINT`/`S3_BUCKET` are unset, which after #80 throws at boot in production.
