From 27919027fec991f50f5800a2604d1e52c9b37a31 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?V=C3=ADctor=20Falc=C3=B3n?= Date: Sat, 4 Jul 2026 20:57:58 +0200 Subject: [PATCH] chore: harden Inertia boundary, CI type-check, and test isolation (#640) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Summary Wave 1 hardening: privacy/security quick wins on the Inertia boundary, a CI safety net, and stricter test isolation. Four focused changes plus two review fixes, each in its own commit. No dependency or product-behavior changes. ## Changes (by commit) 1. **Hide sensitive User fields from serialization** — `User::$hidden` only covered password / 2FA / remember_token, leaving Cashier billing columns (`stripe_id`, `pm_type`, `pm_last_four`, `trial_ends_at`) and the legacy `encryption_salt` exposed in every serialized User, including the Inertia-shared `auth.user` prop. None are read by the frontend and Cashier keeps reading them server-side, so hiding them is invisible to the UI and billing. 2. **Advisory frontend type-check in CI + duplicate `currency_code` fix** — the CI linter job never ran `tsc`, so type errors accumulated unseen. Adds a `Type Check Frontend` step running `bun run types`. It is `continue-on-error: true` on purpose: the codebase already carries ~157 pre-existing `tsc --noEmit` errors, so gating on it now would turn CI red on unrelated code. It surfaces type output today and should be flipped to blocking once the backlog is cleared. Also removes a duplicate `currency_code` member on the `User` TS interface (declared twice, `CurrencyCode` and `string | null`); the TS language server flags it, `tsc` masks it under `skipLibCheck`. 3. **Move residual-encryption cleanup out of Inertia `share()` into a queued job** — `share()` is a shared-data provider and must be read-only, but it ran a `DELETE`+`UPDATE` against the user on every non-API web GET to purge the leftover encryption salt / `EncryptedMessage` once a user had no encrypted data left. The existing `encryption:*` commands do not cover this case (both target users who *still* have encrypted data; this finalizes users who *finished* decrypting). The work now goes to a new idempotent `PurgeResidualEncryptionArtifactsJob` dispatched from `share()`, preserving the eventual-cleanup semantics without writing during the render. 4. **Block stray HTTP in the Feature test suite** — adds `Http::preventStrayRequests()` in a Feature-scoped `beforeEach` so any unfaked outbound request fails loudly instead of hitting the network. A representative HTTP-touching subset (open banking, exchange-rate/currency, AI categorization + AI/stats reports, analytics, Discord, Stripe, bank logos) was run with the guard active; no test relied on a real request, so no fakes had to be added. ### Review fixes (after the two-reviewer pass) 5. **Purge check uses `name_iv` source of truth, not the stale `encrypted` flag** — the destructive purge decided "no encrypted accounts" from `accounts.encrypted`, a flag the codebase already treats as unreliable (see the `align_accounts_encrypted_flag_with_plaintext_names` migration and `FindsUsersWithLegacyEncryption`, which key off `name_iv`). An account with an encrypted name but a stale `encrypted=false` flag could have its key material destroyed. The job's guard now matches the canonical `*_iv` predicate exactly; the loose flag gate in `share()` is kept only as a cheap dispatch filter, and the job re-verifies with the safe predicate before touching anything. 6. **Deduplicate purge dispatches with `ShouldBeUnique`** — `share()` runs on every web GET, so an affected user re-enqueued the job on each page load until a worker cleared the salt. The job is now `ShouldBeUnique` keyed by user id, collapsing repeat dispatches into one pending job. ## Test plan - New/updated tests, all green: - `InertiaSharedDataTest`: `auth.user` omits all sensitive fields; a web GET no longer mutates the user inline and instead queues the cleanup (and does not queue it when there is no salt). - `PurgeResidualEncryptionArtifactsJobTest`: clears salt + message when no `*_iv` data remains; keeps them when an encrypted transaction, an encrypted account name, or a stale-flag-but-encrypted-name account exists; no-op when salt already null. - `StrayHttpRequestGuardTest`: an unfaked request throws `StrayRequestException`; a matched fake still resolves. - Green locally: `vendor/bin/pint --test`, `bun run lint` (0 errors), `bun run format:check`, `bun run test` (254 frontend tests), targeted backend `--filter=InertiaSharedData|PurgeResidualEncryptionArtifactsJob|StrayHttpRequestGuard|Encryption` (24 tests). Ran ~700 HTTP-touching Feature tests with the stray-request guard active with no guard-induced failures. - `bun run types` still reports the ~157 pre-existing errors (unchanged set; this PR adds none) — that is exactly why the CI step is advisory for now. ## Reviewer findings — addressed vs deferred **Addressed** - 🟠 Destructive purge keyed off the stale `accounts.encrypted` flag instead of the `name_iv` source of truth → fixed in commit 5 (job now mirrors `FindsUsersWithLegacyEncryption`; added a regression test for the stale-flag case). - 🟡 Per-request dispatch amplification with no dedup → fixed in commit 6 via `ShouldBeUnique`. **Deferred (with rationale)** - 🟠 "Three divergent copies of the legacy-encryption query" — substantively resolved: the job now matches `FindsUsersWithLegacyEncryption` exactly. The only remaining `encrypted`-flag use is the `hasEncryptedAccounts` **UI prop** in `share()`, which is a separate, pre-existing frontend concern; changing it would alter which accounts the UI treats as encrypted and is out of scope here. A full extraction into one shared scope would require restructuring the trait (it builds a `User` query, not a per-model boolean) and is not a Wave 1 quick win. - 🟢 Redundant `->fresh()` / null guard in the job — kept deliberately: it is the idempotency guard that makes the re-check read committed state on the sync path (the second reviewer credited it as what makes repeat dispatches safe). - 🟢 `continue-on-error` shows the type-check step green — acknowledged; flipping to blocking (or failing on an increase over a committed baseline) is the follow-up once the ~157-error backlog is cleared. - 🟢 (Product review) Theoretical one-request SSR/client `hasEncryptionSetup` diff from async salt clearing — invisible in practice (the lock button gates on `hasEncryptedAccounts || hasEncryptedTransactions`, false in both SSR and client), and `ssr.tsx` is untouched. No action. Product-bug reviewer verdict: no user-facing regressions. Hiding the 5 fields does not affect Cashier (raw attribute access), `EncryptionController`, notifications, or any API/JSON path; the `currency_code` dedup is runtime-identical; the cleanup timing change is client-absorbed. --- .github/workflows/ci.yml | 8 ++ app/Http/Middleware/HandleInertiaRequests.php | 13 +-- .../PurgeResidualEncryptionArtifactsJob.php | 72 ++++++++++++++++ app/Models/User.php | 5 ++ resources/js/types/index.d.ts | 1 - tests/Feature/AccountControllerTest.php | 5 ++ tests/Feature/InertiaSharedDataTest.php | 56 +++++++++++++ tests/Feature/LoanTest.php | 5 ++ ...urgeResidualEncryptionArtifactsJobTest.php | 84 +++++++++++++++++++ tests/Feature/StrayHttpRequestGuardTest.php | 16 ++++ tests/Pest.php | 50 +++++++++++ 11 files changed, 308 insertions(+), 7 deletions(-) create mode 100644 app/Jobs/PurgeResidualEncryptionArtifactsJob.php create mode 100644 tests/Feature/PurgeResidualEncryptionArtifactsJobTest.php create mode 100644 tests/Feature/StrayHttpRequestGuardTest.php diff --git a/.github/workflows/ci.yml b/.github/workflows/ci.yml index ac174979..f483354e 100644 --- a/.github/workflows/ci.yml +++ b/.github/workflows/ci.yml @@ -262,6 +262,14 @@ jobs: - name: Lint Frontend run: bun run lint + # Advisory for now: the codebase carries a backlog of pre-existing + # `tsc --noEmit` errors that predate this step, so it must not gate + # merges yet.
