fix(entity): the tenant comes from the actor, not from the caller - #89
Merged
Conversation
`hasOrgPredicate` returned true when ANY predicate sat on the tenant column and
never compared its value to the acting actor, so the blessed idiom — an `orgId`
arriving as action input and passed into the query — satisfied the guard
completely while reading another tenant's rows. Reproduced first as a failing
test: two tenants seeded, actor in org A, `findMany({ orgId: ORG_B })` returned
org B's row.
The fix derives the tenant instead of accepting it. `scopedPlan()` reads
`tryUseContext()?.actor.orgId` from the ambient context — the same ALS
`coalesce.ts` already uses, so no new channel and nothing for a call site to
forget — and every repository operation funnels through `readPlan()`, so there
is one derivation and no driver can drift from it.
A caller-supplied tenant that differs from the actor's now throws
X_TENANCY_ACTOR_MISMATCH naming both values, rather than being silently
overridden: rewriting the predicate would answer the wrong question correctly
and ship the bug. An equal one is a restatement and still passes, so
`{ orgId: ctx.actor.orgId }` keeps working unchanged.
An actor carrying no tenant is refused (X_TENANCY_ACTOR_ORG_REQUIRED) — an actor
inside no org has no tenant-scoped row that is theirs, and letting the caller's
value stand there would leave the hole open on exactly the unauthenticated path.
Legitimate cross-tenant reads stay possible and become greppable:
`crossTenant(reason, fn)` is an ALS scope with a required non-blank reason, gated
on the `tenancy:cross` actor scope (a scope, not a role — `@ultimat3/auth` mints
scopes only from API keys and service tokens, never a browser session). The
capability is proven twice, at the call and again at every plan built inside,
because `withChildContext({ actor })` swaps the actor without closing the scope
— without the re-check, impersonating inside a sweep would inherit cross-tenant
reach. Outside any request context it is refused too: a sweep nobody can be
attributed to is ambient authority.
Corrected a false claim in the code: tenancy.ts promised "a build-time check in
x verify that no query for a tenant-scoped entity is constructed without it".
The gate's 17 steps check none, and one cannot usefully exist — the tenant is a
request-time value, which is why the plan seam is the enforcement.
New codes: X_TENANCY_ACTOR_MISMATCH, X_TENANCY_ACTOR_ORG_REQUIRED,
X_TENANCY_CROSS_DENIED. X_TENANCY_UNSCOPED's fix line no longer leads with
"pass { orgId }".
Known residual, deliberately out of scope: write values are still
caller-supplied. `insert`/`insertAll`/`upsertAll` build no read plan, so a row
literal carrying another tenant's orgId is still written; only the
`onMatch: 'update'` conflict-target rule guards that path.
docs: axiom 8 — Ultimate ships mechanism; your app ships convention
------------------------------------------------------------------
The framework's most important property was undocumented: an app can wrap a
primitive in its own factory and everything downstream treats it identically,
because `isAction` is structural, `nameAction` stamps in place, and no `x verify`
step matches primitive source text — every fact reaches the gate through
`loadApp` reading the runtime registries. Verified by compiling real factories,
not by reading.
So `tenantEntity()` is how this PR's guard becomes structural rather than
remembered. docs/idea/19-mechanism-not-convention.md states the axiom, the
mechanism/convention test, why value-returning functions extend where base
classes do not, and the three worked decisions. wiki/Building-Your-Own-Base.md
is the app-author page, including both caveats an author will hit.
Structural conventions ship — naming, layout, tiers. Business conventions do not:
what an org is, what a plan tier grants, what an audit row carries. Which is why
this PR ships the tenancy mechanism and no org entity.
Also: token efficiency filed on the scale ladder as "reasoned, never measured",
with the falsifying experiment named and no number invented. Stale status lines
fixed in README.md, llms.txt, docs/idea/README.md and wiki/Home.md (1.0.0/1.1.0
and 27/28 packages against a real 1.2.0 and 29). The `no NPM_TOKEN` clause
dropped from prose; kept in .coderabbit.yml, where it is a review rule, and in
CHANGELOG.md, which records what was true at a shipped version.
Gate: bun run verify — 14 of 17 passed, 3 skipped. Reference-app gate: every pin
holds. 522 entity tests, 0 failures; the leak test written and run red first.

Two pg-driver live tests entered runWithContext(createContext()) with an
anonymous actor and then read a tenant-scoped entity, which the derived guard
now correctly refuses. They pass locally without TEST_DATABASE_URL and only run
against a real Postgres, which is why CI caught what the local gate did not.
The tests were wrong, not the guard. They enter a context only because
coalesceFindById returns undefined without one (coalesce.ts:127) — so the claim
they exist to prove, one statement instead of five, evaporates outside a
request. A bare createContext() was standing in for "a request"; a real request
carries an authenticated actor. Neither test asserts anything about tenancy:
both assert statement counts, bind lists and returned rows.
The { orgId } arguments stay, deliberately. They now restate the actor's own
org, which makes them additional proof rather than noise: the assertions pin
`"id" in ($1, $2, $3, $4)` with values [id, id, id, id, acme, 4], so a duplicated
tenant predicate would surface as an extra bind. Counts, binds and rows are
byte-identical to the pre-change expectations.
Also pinned the coalescing ordering hazard, which turned out not to exist:
findById builds the plan through readPlan -> scopedPlan and passes that plan
into the coalescer, so a batch cannot exist before the tenant is on it, and the
batch map is keyed on context identity — withChildContext mints a new context,
so an impersonated actor gets its own map. Two tests now hold that: a derived
tenant reaching the batch with no caller naming one, and an impersonated actor
never joining the batch it did not open.
Live: 45 pass, 0 fail across six entity live files against a real Postgres.

Inline comments:
In `@docs/idea/README.md`:
- Around line 55-61: Update the thesis entry near the document’s opening to say
“the 8 axioms” instead of “the 7 axioms,” keeping the existing wording and links
unchanged.
In `@packages/entity/src/cross-tenant.test.ts`:
- Around line 74-93: Update the shared repository write path used by memoryRepo
and the PostgreSQL repository to guard insert, insertAll, and upsertAll
operations against the actor’s tenant scope. Add tests covering rejection
outside crossTenant, successful writes within crossTenant, and rejection for an
impersonated child actor, while preserving existing read behavior.
In `@packages/entity/src/errors.ts`:
- Around line 114-129: Update tenancyActorMismatch so the userActor orgId
expression in the fix message uses the named tenant only when init.named is a
string; otherwise substitute a pasteable placeholder for arrays, undefined, and
other non-scalar values. Keep the cause message and existing scalar behavior
unchanged.
In `@packages/entity/src/index.ts`:
- Line 21: Update the public export block in packages/entity/src/index.ts to
stop exporting crossTenantReason, keeping it internal to the tenant guard and
crossTenant implementation. Also make the tenancy error constructors consistent:
either export all four of tenancyUnscoped, tenancyActorMismatch,
tenancyActorOrgRequired, and crossTenantDenied, or remove tenancyUnscoped from
the public surface; use the smaller all-internal surface.
In `@packages/entity/src/jit-preload.test.ts`:
- Around line 81-91: Centralize the duplicated acrossTenants helper and remove
both local definitions. In packages/entity/src/jit-preload.test.ts lines 81-91,
import and use the shared helper; in packages/entity/src/coalesce.test.ts lines
74-86, import and use the same helper while retaining local inRequest if its
actor differs. Establish one consistent service-actor orgId behavior for
cross-tenant requests.
In `@packages/entity/src/tenancy.test.ts`:
- Around line 208-216: Update the mismatch test around scopedPlan to avoid
throwing a bare Error when no exception occurs; capture the thrown value and
assert its error code is X_TENANCY_ACTOR_MISMATCH before inspecting cause.
Preserve the existing assertions that the cause includes ORG_A and ORG_B.
In `@packages/entity/src/tenancy.ts`:
- Around line 156-171: Update verifyScope and tenancyUnscoped so unscoped errors
distinguish actor-present from context-free calls: pass the actor state when
invoking tenancyUnscoped, use the actor-present cause and an orgScoped(...) or
scopedPlan(...) fix when actorOrg exists, and retain the context-free behavior
otherwise. Add a regression test covering assertScoped invoked within
runWithContext with an actor orgId.
In `@README.md`:
- Line 16: Update the README status statement so it does not claim that all 29
packages, including `@ultimat3/flags`@1.2.0, are published on npm in lockstep
unless registry validation confirms it. Prefer adding release validation that
checks every package version, including `@ultimat3/flags`, before asserting the
npm, commit, tag, and provenance claims; otherwise remove those claims until
publication is complete.
In `@wiki/Error-Codes.md`:
- Around line 138-141: Update the X_TENANCY_ACTOR_MISMATCH remediation to make
cross-tenant reads actionable: state that crossTenant requires an actor with the
tenancy:cross capability and must run inside runWithContext(createContext({
actor }), fn), or reference the complete remediation already documented for
X_TENANCY_CROSS_DENIED.

…de, export surface
Nine CodeRabbit findings: six accepted, one rejected with evidence, one stopped
for its own PR, one docs claim that was wrong and is now honest.
X_TENANCY_ACTOR_MISMATCH's fix line could not run. `verifyScope` rejects
non-`eq` operators, so the named tenant is an array from `where('orgId','in',…)`
and undefined from `is-null` — rendering `orgId: ["a","b"]` and
`orgId: undefined`. Non-strings now render as the '<org>' placeholder in the
FIX; the CAUSE still prints what was actually named, because a cause describes
and only a fix has to parse. error-contract.ts cannot catch this class:
staticFix() blanks every ${…} before its rule runs.
X_TENANCY_UNSCOPED answered two different situations with one cause. The
verify-only `assertScoped` can refuse an unscoped plan while an actor DOES carry
a tenant, and the cause then claimed "no request context carried an actor",
which was false. Cause and fix now branch on actor presence, through an optional
parameter so the shipped signature still compiles. No fourth code: the situation
is one — this plan is not scoped — and only the remedy differs, which is what
flags' flagTargetingInvalid already solves by branching its fix.
crossTenantReason is no longer exported: it hands apps a second way to reason
about tenant scope, and it is semver-locked the moment it ships. The three error
factories stay exported — every error factory in this package is public, and a
third-party Driver must be able to raise the same tenancy refusals the two
shipped drivers do.
Three `throw new Error('expected a throw')` sentinels in tenancy.test.ts — one
added here, two predating it — now go through the local `caught()` helper six
other test files in this package already define, and each assertion checks the
code via toBeUltimateError before inspecting the cause.
Rejected: extracting the duplicated `acrossTenants` test helper. The two copies
are byte-identical, so there is no disagreement to drift from; the package's
convention is per-file helpers (`caught` in six files, `inRequest` in three);
and package.json ships "files": ["src", "!src/**/*.test.ts"], so a shared helper
— which cannot be named *.test.ts and stay importable — would be published to
npm inside the tarball. A test helper shipped to consumers is worse than six
identical lines.
Stopped, for PR 3: the write path is unguarded. Verified rather than assumed —
inside a request with an actor in org A, `repo.insert({ orgId: B, … })` writes
the row. Pre-existing and unchanged here. It needs one hook in memoryRepo's
write() and three in the pg driver (writeRows, update's bindValues,
updateWhere's), because plan.ts's own header says a guard only one driver
applies is worse than none. And "absent means derived" would be a new
capability, not a refusal: stamping the actor's tenant onto an inserted row
creates data from ambient state and changes which row an upsert's conflict
target collides with. That is a design call, not a review-fix.
docs: README and docs/idea/README claimed 1.2.0 is on npm in lockstep. Verified
against the registry: @ultimat3/core and @ultimat3/entity are at 1.2.0,
@ultimat3/flags 404s — it has never been published (#84). Both now say so.
docs/idea/README also said 7 axioms.
Gate: bun run verify — 14 of 17 passed, 3 skipped. 526 entity tests, 0 failures;
45 live tests against a real Postgres, 0 failures.

…, audit any mutation, run backfills (#90) * feat(tier2-3): close the tenancy write path, declare rate-limit scope, audit any mutation, run backfills Four slices from the same audit of five production codebases. All four are mechanism, not convention (axiom 8): correct-or-incorrect whatever the business. entity — the write path ----------------------- #89 derived the tenant on reads and left writes caller-supplied. Reproduced first: inside a request with an actor in org A, `repo.insert({ orgId: B, … })` wrote the row. Five seams now check it — memoryRepo's write(), the pg driver's writeRows(), and both update paths' bindValues() — because plan.ts's own header says a guard only one driver applies is worse than none. Writing the parity test surfaced a bug in the first cut: memory's insertAll mapped the guard per row, so a batch whose second row named another tenant stored the first and THEN threw — a half-applied batch, which Postgres cannot do and CLAUDE.md forbids. REFUSE, never stamp. Stamping an absent tenant looked ergonomic and breaks three ways: it adds a column to the insert the caller never wrote; it silences upsertPlan's uneven-batch refusal, letting a column default land where `excluded.<col>` was meant; and under `onMatch: 'update'` the tenant column is required in the conflict target, so a stamped value would decide WHICH STORED ROW gets overwritten — ambient state picking the collision. An author still writes `orgId: ctx.actor.orgId` on inserts; that gap is recorded, not forgotten. The upsertAll cross-tenant hazard is now unrepresentable rather than documented, and it needs both halves: the conflict target must contain the tenant column (which stored row a collision lands on) AND every incoming row must name the actor's tenant. The second matters because `onMatch: 'nothing'` skips a colliding row BEFORE the write guard, so checking stored rows alone would have passed exactly the rows that collide. No new code: X_TENANCY_ACTOR_MISMATCH is reused via a second factory. One situation — a caller-chosen tenant that is not the actor's — in a different argument. Its registered title moved from "a query named" to "a call named". Residual, named not fixed: under `onMatch: 'nothing'` with a target excluding the tenant column, colliding with another tenant's row writes nothing but omits your row from the result. An existence leak, not a data leak; closing it would break the use the exemption exists for. http + auth — a rate limit that says where it lives --------------------------------------------------- Counters were per-replica in two separate private Maps, so `web: replicas: 3` enforced 3x every configured bucket and account lockout was 5 x replicas, with a lockout on one replica invisible to the others. The documented escape hatch was closed by its own signature: AuthLimiter was synchronous while its comment promised "a multi-process deployment passes a shared implementation". And the one real async seam, RateLimitStore, was unreachable — createServer never accepted or forwarded a limiter, so memoryRateLimitStore was what every deployment ran. `scope: 'process' | 'shared'` is now declared twice and compared once: the store says where its counters live, the app says what its deployment requires, and createPipeline/defineAuth refuse a mismatch AT BOOT. Declared, not inferred — every inferable signal lies somewhere: replicas live in a compose file the process never reads, NODE_ENV is missing from plenty of prod containers, K8s exposes no replica count without an API call the framework must not make, and one replica today is three after a scale. A guess wrong in the unsafe direction is silently 3x the limit. Both default to 'process', so nothing changes until an app opts in. No dev exemption, and `enabled: false` under `scope: 'shared'` is refused too — a fleet-wide limit switched off is a claim with nothing behind it. AuthLimiter is now async. Breaking, and authorised: #87 is open and the next release is a major. Converting the suite exposed seven existing assertions that had silently gone vacuous — `expect(limiter.lockedUntil(k)).not.toBeNull()` on a Promise always passes — so the bounded-table guarantees are tested again. No Redis adapter here. http and auth are tier 2 and cannot import a tier-3 home; the seam is now reachable, declared and refusable, which is the part that was missing. action — audit on any mutation ------------------------------ Audit stopped at the admin boundary: it required an AdminActor and a permission and was called only from admin/crud.ts, so an action writing a row anywhere else recorded nothing. Four of the five audited codebases hand-rolled their own. The argument for a framework seam is not recurrence, it is the DENIED record: guard() throws before handle, so nothing an app writes around its own handler can observe a refused attempt — and a denial is the row an auditor wants. Mechanism is that a mutation can be recorded and what the framework honestly knows; convention is what the row says, and that is left to the app. No audit entity, schema, retention, backend, hash chain or opinion on what "who" means under impersonation. Parsed input is carried (a denied record has no handler run to recover it) but never the raw payload — handing an unvalidated body to a sink that writes it to a table is how an audit trail becomes an injection surface. `result` is excluded: reachable from the handler on the one outcome that has one. Sink failure splits on one rule — an audit failure never replaces a failure the action already had. A refused `allowed` record fails the invocation (X_AUDIT_SINK_FAILED); a refused denied/failed record is logged and the original error still reaches the caller, because answering otherwise would hide the X_FORBIDDEN and make the audit backend's health an oracle. This is deliberately the opposite of cache's bestEffort: a dropped cache entry is re-derived, and nothing ever re-derives an audit row. Caught while building: a refused `allowed` record was re-recorded as `failed`, so the trail would claim an action failed for a handler that had committed. jobs + cli — backfills that actually run ----------------------------------------- The ledger was never the gap. x_backfills is real, per-database and blocks a completed name, so a redeploy does not re-run a cleanup. Nothing knew what was PENDING: backfill() returned an undifferentiated JobHandle, both inspection surfaces read the ledger only, and `x db backfill <name>` threw "runs nothing yet". An author could scaffold, merge and deploy, and it silently never ran. Now: a registry via the WeakMap origin pattern task.ts already uses (no app-side registration — that coupling is what axiom 8 refuses), a declared-minus-completed `--pending` that exits non-zero, and `x db backfill <name>` that runs one. Dry run by default; --write never implied; --all isolates per name and continues past a failure so one wedged cleanup cannot block every later one. Deploy TRIGGERS, deploy never GATES. ROLE=migrate throws on drift to fail the deploy; a slow UPDATE there holds it open against a database still serving the previous release. So `backfill` is a deploy step that runs after the new pods serve, and the compose service behind it is added here and in the scaffold template. Backfills are not wired into runMigrations(). `environments` ships as declared data plus a mismatch error, never a hardcoded "cleanups are production" — a staging rehearsal is correct practice. No dependsOn graph: the real dependency is "after code tolerating both shapes is serving", which the framework cannot observe. Fixed an axiom-4 violation in generated code: every scaffolded backfill shipped `fix: 'x jobs enqueue <name>'`, and x jobs enqueue does not exist. It was the only occurrence in the repo; a test now asserts JOBS_SUBCOMMANDS lacks it. New codes (11): X_TENANCY unchanged; X_RATE_LIMIT_NOT_SHARED, X_AUTH_LIMITER_NOT_SHARED, X_AUDIT_SINK_MISSING, X_AUDIT_SINK_FAILED, X_BACKFILL_{PENDING,APPLIED,ENVIRONMENT,MIGRATION_PENDING,RUNNING,STALLED,UNKNOWN}. X_BACKFILL_WRITE_UNCONFIRMED was rejected: a dry run that wrote nothing did what it was asked. Also: SECURITY.md said rate limiting was per-replica with no recourse — half of that is now stale. README gets a logo and the Agent Smith line, and its version badge said 1.1.0 against a 1.2.0 status. Gate: bun run verify — 14 of 17 passed, 3 skipped. Reference-app gate: every pin holds. 322 error codes. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * docs: inspire explicitly, and say why an agent-first framework is worth it The image and the logo were competing at the top of the README, so the meme moves below two paragraphs that earn it. Those paragraphs say the thing the README never said out loud: a coding agent works 24/7/365, and — the part that matters — it writes the tenth feature the way it wrote the first. No Friday-afternoon shortcut, no second way of doing a thing because someone new joined. Consistency at volume is what humans are worst at and agents are best at, and it only pays off if the framework agrees: one way per thing, conventions as build errors, errors carrying their own fix, docs local, --json everywhere. "Steal explicitly" is now "Inspire explicitly". Same table, honest name — we studied these frameworks and changed what aged badly, which is not stealing. Two rows added, each naming a specific idea rather than a nod: - Play: routes verified at compile time. We go further — the directory IS the URL, so there is no routes file to drift from its handler. - Angular: the CLI as the primary surface, and upgrades shipped as migrations rather than release notes. We take the first wholesale; the second differently, because an agent reading a machine-readable surface diff edits with judgement where a schematic guesses from syntax. Spring's row gains the half that was missing — module boundaries verified by the build, which is what `bun run boundaries` is — and names what we deliberately do not take: a DI container, runtime reflection, and configuration that surfaces its error three layers from the cause. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * docs: why Bun and why SolidJS, as reasons rather than preferences Both picks remove a layer an agent would otherwise reason about, which is the only defence either needs. Bun is one toolchain where there were six, so there is no tsconfig-versus-bundler-versus-test-runner disagreement to debug. It runs TypeScript directly, which is why the npm tarball IS the source you read — no dist/, no source-map hop when an agent steps into node_modules. And its natives are why the whole framework has two third-party runtime dependencies: HTTP, WS, hashing, SQLite, bundling and test running are already there, so most of what a framework would reach for is not a decision at all. SolidJS compiles away. An update touches the one text node that changed, and there is no re-render model to hold in your head — no dependency arrays, no memo hooks, no rules about where state may be read. That pays twice: the runtime is small enough that `render: 'static'` genuinely ships zero JavaScript, and the mental model is small enough that an agent writing its four-hundredth component is not carrying a rulebook about stale closures. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix: address review — swallowed db failures, identity selection, hostile error values Twenty CodeRabbit findings across the four slices. Four were real bugs; two of the suggested fixes were wrong and a better condition was found instead. jobs/cli — the four that mattered --------------------------------- `readAppliedMigrations` swallowed EVERY database failure and returned undefined, which `gateBackfill` reads as "no obstacle" — so a permission error, a timeout or a dropped connection made `requires` silently PASS. That is the exact hole this slice exists to close. Three distinct answers now: the ids, `[]` when x_migrations is genuinely absent (so every `requires` blocks), and `undefined` only when no declaration carries `requires` at all. Everything else rethrows. `--all` selected by object identity — `report.pending.includes(row)` held only because pendingBackfills happens to filter the array it returns. A clone would have made `--all` sweep NOTHING and exit 0, which is the silent-success class this whole slice removes. Now selected by state, through an exported PENDING_BACKFILL_STATES rather than a second inline literal. `count()` was unvalidated, and the failure mode is the detector's own: NaN > 0 and -1 > 0 are both false, so a bad number read as "converged" and wrote the completed ledger row that stops the next deploy re-running the sweep. `blocked: rows.length - enqueued` counted a deduped pass as blocked, so the human summary contradicted --json. The three counts now add up to the run. The release barrier is real, not implied. `docker compose up -d` returns when a container STARTS, so listing backfill last only looked like "after". Both compose files gain `depends_on: web: service_healthy`. action — the fix line branches on the invocation, not the declaration --------------------------------------------------------------------- X_AUDIT_SINK_FAILED told the caller to retry under the same Idempotency-Key. The review proposed requiring `idempotent: true`. That would still have lied: the key is ALSO null when the action is idempotent and the caller sent no header. It branches on `record.idempotencyKey !== null` instead — the invocation's own fact, true in all three cases rather than two — and refuses to couple `audit` to `idempotent`, which would force an idempotency store on anyone who wants only a trail. auth — compare the policy, do not hand it over ----------------------------------------------- A custom AuthLimiter received the resolved rateLimit numbers nowhere, so `Auth.rateLimit` — what an operator reads as "what this deployment enforces" — had nothing behind it. The review proposed a limiter factory; a factory hands the numbers over but cannot make an implementation honour them. Comparison is the mechanism this slice already uses: AuthLimiter.policy is declared, compared once, refused at boot. maxKeys is deliberately excluded — it bounds one process' table, so a shared limiter has no opinion on it. entity + flags — an error constructor must not lose its refusal ---------------------------------------------------------------- Ran the hostile values rather than reasoning about them: three of five destroyed the tenancy refusal, one more than the review anticipated. JSON.stringify throws on a bigint and on a cycle, and it RUNS a toJSON the value carries — so an app object hijacks the error path with its own throw, and `error.code === 'X_TENANCY_ACTOR_MISMATCH'` finds nothing to catch. The write was still refused, so this was never a data leak; what was lost is the diagnosis and the HTTP status. Causes now degrade to a type name; fixes fall back to a placeholder. A cause describes, so a type name costs a reader nothing; a fix must parse. The same class was live in `packages/flags`, which is already SHIPPED — flagExpiryInvalid stringifies an `unknown`. Fixed here rather than left alive in a package this PR already touches, with six hostile-value tests proven non-vacuous. Also: split db-backfill.test.ts at what the command SHOWS versus what it DOES; README heading order; three fix lines that appended prose to a runnable command, which matters because a fix is copied verbatim. Gate: bun run verify 14/17, 3 skipped. Reference-app gate: every pin holds. 323 error codes. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix: second review pass — a vacuous test, a fix that asked the reader to decide flags: my own hostile-value test was vacuous for one of six cases. JSON.stringify({ toString: throws }) answers '{}' without ever calling toString, so that case never reached the String(given) fallback it was written to exercise. The hostile shape is a FUNCTION — stringify returns undefined, which falls through to String(given), where the throw lands. Verified, not assumed. A second test now pins the trap itself: if the fixture ever stops being hostile, that assertion fails rather than the suite quietly passing. Both fixture throws also raised a bare Error, in a repo whose rule has no test exemption. They now raise flagUnknown(), through one named appThrow() helper so the intent reads as the app's own failure. auth: X_AUTH_LIMITER_POLICY_MISMATCH's fix offered two edits joined by "or". The defect was not that a fix names a code change — errors.ts's header explicitly allows that, and three shipped codes already do — it was that two alternatives with no guidance make the reader decide, and a fix that requires a decision is not a fix. One edit in `fix`, the alternative demoted to `cause`. The limiter is the half that moves, because the declaration is what Auth.rateLimit reports. The two NOT_SHARED codes deliberately keep their two-branch form: there the second branch is an explicit downgrade of the declared safety posture, not a typo correction, so the framework presents it rather than choosing for the operator. Both lead with the safe branch. Also: dated the "no shared limiter/store ships yet" claims in both READMEs, the kind of sentence that goes stale silently; README wording; and a wiki paragraph that had become false inside this same PR — it said the backfill service was in neither compose file, which stopped being true when the readiness barrier was added.

The vulnerability, reproduced
hasOrgPredicatereturned true when any predicate sat on the tenant column and never compared its value to the acting actor. So the blessed idiom — anorgIdarriving as action input and passed into the query — satisfied the guard completely while reading another tenant's rows.Reproduced as a failing test before any change: two tenants seeded, actor in org A, and
findMany({ orgId: ORG_B })handed back org B's row.The reference app fed exactly that shape from
t.uuidaction inputs at ~15 sites, so this was the documented way to use the framework.The fix: derive, never accept
scopedPlan()readstryUseContext()?.actor.orgId— the same ALScoalesce.tsalready uses, so no new channel and nothing a call site can forget. Every repository operation funnels throughreadPlan(), so there is one derivation and no driver can drift from it.X_TENANCY_ACTOR_MISMATCH, naming both values. Deliberately not overridden — silently rewriting the predicate would answer the wrong question correctly and ship the bug. An equal one is a restatement and still passes, so{ orgId: ctx.actor.orgId }keeps working.X_TENANCY_ACTOR_ORG_REQUIRED). An actor inside no org has no tenant-scoped row that is theirs, and accepting the caller's value there would leave the hole open on precisely the unauthenticated path.crossTenant(reason, fn)is an ALS scope with a required non-blank reason, gated on thetenancy:crossscope — not a role, because@ultimat3/authmints scopes only from API keys and service tokens, never a browser session. The capability is proven twice, at the call and again at every plan built inside, becausewithChildContext({ actor })swaps the actor without closing the scope; without the re-check, impersonating inside a sweep would inherit cross-tenant reach. Outside any request context it is refused too — a sweep nobody can be attributed to is ambient authority.A false claim in the code, corrected
tenancy.tspromised "a build-time check inx verifythat no query for a tenant-scoped entity is constructed without it." The gate's 17 steps check none, and one cannot usefully exist: the tenant is a request-time value, which is exactly why the plan seam is the enforcement.Migration
orgIdonto the actor at the request boundary —@ultimat3/auth'sactorFrom*already carry it.orgIdthrough handlers.db.posts.where({ status })is now correct on its own.crossTenant(reason, fn)and granttenancy:cross.Known residual, deliberately out of scope
Write values are still caller-supplied.
insert/insertAll/upsertAllbuild no read plan, so a row literal carrying another tenant'sorgIdis still written; only theonMatch: 'update'conflict-target rule guards that path. Named here rather than left silent.docs: axiom 8 — Ultimate ships mechanism; your app ships convention
The framework's most important property was undocumented: an app can wrap a primitive in its own factory and everything downstream treats it identically.
isActionis structural,nameActionstamps in place, and nox verifystep matches primitive source text — every fact reaches the gate throughloadAppreading the runtime registries. Verified by compiling real factories, not by reading them.That is what makes this PR's guard structural rather than remembered: an app writes
tenantEntity()once and the tenant column is true for every table.docs/idea/19-mechanism-not-convention.md— the axiom, the mechanism/convention test, why value-returning functions extend where base classes do not, and the worked decisions.wiki/Building-Your-Own-Base.md— the app-author page, including both caveats an author will hit.Structural conventions ship (naming, layout, tiers). Business conventions do not (what an org is, what a plan tier grants, what an audit row carries) — which is why this PR ships the tenancy mechanism and no org entity.
Also: token efficiency filed on the scale ladder as "reasoned, never measured", with the falsifying experiment named and no number invented. Stale status lines fixed in
