--- title: "Testing" audience: [developer] summary: "The test taxonomy (unit, DB-gated integration, Stripe-mocked, HTTP render, lint, e2e, OpenSpec validation), the test kit, how to run each, and conventions for new tests." --- # Testing guide How testing works in member-console: the kinds of tests, what each covers, how to run them, and the conventions to follow when writing new ones. ## TL;DR ```bash # The whole suite: lint, a reset of the test databases, then every package # one at a time (needs the test stack up): cd test && ./bootstrap-stack.sh && docker compose up -d # one-time per worktree make test # from repo root # One package while iterating, on the same footing as make test: (cd test && ./reset-test-db.sh) set -a && . test/.env && set +a go test -count=1 ./internal// # Static checks and render discipline: make lint # project lint, golangci-lint, deadcode, unused sqlc queries make lint-templates # no handler bypasses SafeTemplates ``` `go test ./...` with no database configured is always safe to run: every database- or Stripe-backed test **skips itself** when `TEST_DATABASE_URL` is unset. With it set, a database that `reset-test-db.sh` has not migrated fails the test instead of passing on a stale schema. ## The `test/` directory — the local stack Most Go test files sit next to the code they cover (`internal/.../_test.go`). `test/` is the exception, and serves two roles: it's the **integration/e2e environment** — a Dockerized stack of every backing service the app needs (Postgres, Valkey, Keycloak/OIDC, Temporal, FedWiki) that the database-gated tests (types 2–3) and the e2e suites (type 7) run against — **and** it houses the higher-level **end-to-end Go test suites** under `test/e2e/`. Its role: - **Provides the backing services.** `test/compose.yaml` brings up Postgres, Valkey, Keycloak, Temporal, and FedWiki, plus one-shot seeders (realm users, FedWiki identity, the Temporal default namespace). - **Isolates each worktree.** `./bootstrap-stack.sh` derives collision-free host ports and writes `test/.env` (`COMPOSE_PROJECT_NAME`, port assignments, and the `MC_*` config overrides), so several worktrees can run their own stacks concurrently without colliding. - **Is where the test databases come from.** `./reset-test-db.sh` drops, recreates and migrates `member_console_test` (`TEST_DATABASE_URL`) and `member_console_e2e` (`E2E_DATABASE_URL`); `make test` runs it first. `test/.env` holds both addresses beside `MC_DB_DSN`, the running app's database, which only the browser tests write. - **Houses the end-to-end Go suites** under `test/e2e/`: `plan-management/` (in-process `httptest` over the real handlers + a migrated DB) and `operator-walkthroughs/` (Go tests that drive a browser against the running stack via `MC_BASE_URL`; `WALKTHROUGH_HEADFUL=1` to watch). Both run under `go test` (see type 7). - **Holds the stack's run-only assets:** `mc-config.yaml`, `secrets/` (gitignored Stripe keys + webhook secret), the opt-in demo seeder (`./test/seed-demo.sh` + `seed/`), and `teardown-stack.sh` (compose down + removes `.env`, `secrets/`, `testdata/`). Don't edit `test/.env` by hand — re-run `bootstrap-stack.sh`. The full contract (idempotency, the account-global Stripe webhook constraint, teardown) lives in [`test/AGENTS.md`](../test/AGENTS.md); read it before running the stack. ## The kinds of tests ### 1. Pure unit tests — no external dependencies Plain Go tests of pure logic: parsing, classification, formatting, guard conditions. They run on every `go test` invocation, need nothing external, and are fast. - **Cover:** webhook payload parsing, status classification, value mapping, small helpers, input guards. - **Examples:** `internal/fulfillment` `TestClassifyStatus`, `TestUnixToNullTime`; `internal/integrations/stripe/workflows` `TestCheckoutSessionPayloadParsing`, `TestInvoicePayloadParsing`, `TestCardStringField_*`. - **Write one when:** the behavior is a function of its inputs with no DB/HTTP/ Stripe dependency. Prefer pushing logic into such functions so it can be tested this way. ### 2. Database-gated integration tests Run against a real Postgres that `test/reset-test-db.sh` has migrated. They exercise queries, constraints (e.g. the `pool_provision_ladders` GiST exclusion, `chk_pool_provisions_source`), transactions, and cross-schema flows that unit tests can't reach. - **Cover:** the entitlement graph, provisioning, fulfillment reconcile, webhook projection, materialization, operator queries. - **Examples:** `internal/provisioning` (`TestAutoProvision…`), `internal/fulfillment` (`TestReconcile_*`), `internal/entitlements/materialize_test.go`, `internal/integrations/stripe/workflows` (`*_Integration`, transition/product-catalog tests). **Opening the database.** Every test reaches the shared databases through `dbtest` (`internal/testkit/dbtest`): - `dbtest.Open(t)` opens `TEST_DATABASE_URL`, closes it when the test ends, and skips the test when the variable is unset. It **never migrates**: the reset script is the only migrator of the shared test database. It fails the test, naming the script, when the core ledger lacks the highest version in `db.BaseSources()`, so a stale database cannot pass a test. The driver is pgx. - `dbtest.OpenE2E(t)` does the same for `E2E_DATABASE_URL`, the database `test/e2e/plan-management` commits its fixtures to. `dbtest.DSN(t)` returns the address (and skips) for a test that needs it itself. - A test whose subject is a migration or the migrator gets an empty database from `dbtest.Scratch(t)`, created in the same cluster and dropped when the test ends, and applies a stream to it with `dbtest.UpTo` or `dbtest.ApplyVersion`, or all streams with `db.RunMigrations` on a `dbtest.Connect` to its address. It skips where the login role cannot create databases. - `dbtest.Counted(t)` opens `TEST_DATABASE_URL` as `Open` does, on a handle that records the name of every statement run on it (`ByName`, `Total`, `Reset`; `Names` lists them in the order they ran, a transaction's `begin`, `commit` and `rollback` included; `Note` puts a line of the test's own among them; `Diff` prints what changed between two records). Hand it to the code under test only and build fixtures on a handle from `Open`, so the record holds the code's statements and nothing else. - `dbtest.Q` runs statements and fails the test on any error (`Exec`, `Scan`, `Int`, `String`, `Refuse` for a statement that must fail with a given SQLSTATE; `Rows` prints a query's rows as text, in the order the query names; a rows golden names the fixture's ids with the test's normaliser and numbers the rest with `golden.Ordinals`). `dbtest.Tx(t, d)` opens a transaction the test rolls back; `dbtest.On(t, x)` binds a statement runner to a test. A `Q` belongs to the test or subtest that built it: a subtest that uses its parent's transaction rebinds with `dbtest.On(t, q.Tx())`. - `dbtest.AwaitLockWait` polls until a backend waits on a lock, for a test that holds one transaction open while a second one blocks. **Fixtures.** `world` (`internal/testkit/world`) builds the rows a test needs through the functions the console itself calls: the identity and organization queries (`Person`, `Org`, which also creates the default pool, and `DefaultLadder`), the catalog queries (`Product`, `EditProduct`, `Ladder`, `AddTier`), the rule-change function (`Rule`, the system's path, and `RuleChange`, a person's commit that settles the carrying pools), the conferral queries (`Confer`), the provisioning step that gives a workspace its pool (`Workspace`) and the provider registration boot runs (`Providers`). Billing accounts, invoices and their lines, and payments (`BillingAccount`, `Invoice`, `LineItem`, `Payment`), the Stripe mappings of billing rows (`MapAccount`, `MapSubscription`, `MapInvoice` and `MapPayment` record no environment; the `...In` forms record one), Stripe product mappings (`MapProduct`, `MapProductIn`), a product without its set (`WithoutSet`), a subscription row with no items (`BareSubscription`) and the grant, tier and subscription acts (`Extend`, `ReorderTiers`, `RemoveTier`, `EndSubscription`) go through the same queries and functions the console calls. `OrgType` is the one raw INSERT, since no console act creates an organization type. `world.New(t, db)` takes any `*sql.DB` the migrations built, so one builder fills the test database or the application database. Every method fails the test on any error. Every organization, product, set, ladder name, subject and email carries the World's suffix, so repeated runs against the shared database do not collide, and nothing is deleted: rows stay in the disposable database until the next reset. A World holds the `testing.TB` it was built with, so a subtest builds its own with `world.New(t, db)`. The first sign-in's rows (user, person, organization with its membership, workspace) come from `provisioning.AutoProvision(ctx, db, claims)`. A test of the schema itself writes its rows by SQL: a constraint, a trigger or a migration is the subject, and a builder that went through the console's functions would not exercise it. ### 3. Stripe-mocked tests A specialization of the integration tests: the Stripe SDK is pointed at an in-process fake so fulfillment's "refetch from the Stripe API" path runs deterministically and offline, with **no live Stripe account**. - **Helper:** `internal/stripetest` — `MockBackend{Sub, List, Err}` implements `stripe.Backend`; `stripetest.Install(m)` swaps the global backend + a dummy key and returns a restore func (`t.Cleanup(stripetest.Install(m))`). `m.OnCall` sees each request as it is recorded, and `stripetest.Line(c)` prints one as text, so `m.OnCall = func(c stripetest.Call) { stmts.Note(stripetest.Line(c)) }` puts each Stripe call among the statements of a `dbtest.Counted` handle. `stripetest.KeyMode` answers the mode of the key the SDK holds when it is called (`"test"` under `Install`); a test passes it where the console passes its configured key mode. - **Cover:** `fulfillment.ReconcileSubscription` scenarios (empty-payload provisioning, idempotent replay, ordering, cancellation, multi-ladder guard) and the webhook→`plan-transitions` end-to-end tests. - **Gotcha:** `Install` mutates **global** stripe-go state, so these tests must **not** call `t.Parallel()`. ### 4. HTTP handler / render tests Exercise handlers through `net/http/httptest` plus the real `SafeTemplates` renderer, session manager (`scs`), and CSRF middleware. - **Cover:** rendered output, template wiring, auth guards (e.g. 401 for unauthenticated), CSRF behavior. - **Examples:** `internal/server/member_upgrade_render_test.go` (`TestMemberPlansUpgradeControlRendering`, `TestDashboardCheckoutBanner`, `TestGetPlansUnauthenticatedReturns401`); `internal/middleware/tests/security_headers_test.go`. - **Template sets come from the constructors production uses.** The server package's test harness (`internal/server/harness_test.go`) builds them: `OperatorSet(t)` is `web.OperatorTemplates` and `MemberSet(t)` is `web.MemberTemplates`, both over `web.CoreTemplates()`, and `Render(t, set, name, data)` executes one template. A test never builds a stand-in set or registers template functions itself. - **Query the output with `htmltest`** (`internal/testkit/htmltest`): `htmltest.Parse(t, body)` parses a page or a fragment, and `One` (exactly one match), `All`, `Count`, `None`, `Text`, `Attr`, `HasClass`, `Before` and `InOrder` select and compare with CSS selectors, the vocabulary the browser walkthroughs use. Select by role and by `aria-*`, `hx-*` and `data-*` attributes (`nav[aria-label=Account]`, `[role="menu"] button[hx-post="/logout"]`); a class that only styles an element is not what a test asserts. A failure quotes the selector and a snippet of the markup. The harness adds `ShellBar`, `ShellRail` and `LinkNamed` for the shell. - **Sign in through `authtest`** (`internal/testkit/authtest`): `authtest.NewSessionManager()` is the in-memory session manager, and `authtest.SignIn(t, sm, signIn)` writes the session through `auth.PutSignIn`, the function the callback handler calls, so a test session has the keys and values a real sign-in produces. `authtest.Get` and `authtest.Post` run a handler in process with that session on the request; `authtest.PathValue` sets a path parameter as the mux would. `Get` and `Post` send no htmx headers, so a handler answers as it does to a native request. `authtest.Cookie` commits that session and returns its cookie, for a handler wrapped in the session middleware, such as the whole router. - **Compare with a golden file through `golden`** (`internal/testkit/golden`): `golden.Compare(t, file, got)` fails unless `got` is the file's content, and `go test -update` writes the file. A golden file is written once, with `-update`, and read against its fixture before it is committed; after that it changes only in a commit that names the change. A `golden.Normalizer` turns the ids a fixture made into names (`Name`) and `golden.Ordinals` numbers the ids and times an act made. A test package that defines its own `update` flag cannot import `golden`, because the flag would be defined twice. ### 5. Static checks (`make lint`) Not Go tests, but part of the green-bar definition. `make lint` runs five checks, and `make lint-templates` is a sixth that runs on its own: - **`go run . lint`** (`cmd/lint.go`) — operator-UI integrity: every registered route and templated URL reference resolves, swap targets exist, pages follow the page anatomy, copy follows the vocabulary rules, and every page route has a screen. It parses each template in the set its surface builds in production (`web.MemberTemplates` and `web.OperatorTemplates`, with each integration's directory as a mount), so a template it cannot parse fails it, naming the file, and so does a file that no surface parses. - **`scripts/notebook-citations.sh`** — no tracked file cites a local notebook path. - **`scripts/golangci-lint.sh`** — golangci-lint with `.golangci.yml`: the standard set (vet, staticcheck, unchecked errors with errcheck, dead assignments with ineffassign, unused code with unused), plus error comparison (errorlint), `rows` and `sql` handling (rowserrcheck, sqlclosecheck), unused parameters (unparam), duplicated code (dupl), function complexity (gocognit, limit 30) and forbidden identifiers (forbidigo), among them the rod waits the browser tests refuse (type 7). - **`scripts/deadcode.sh`** — production functions no program reaches, except those listed in `scripts/deadcode-testonly.txt`. - **`go run ./scripts/sqlc-unused`** — generated queries with no caller outside generated and test files. - **`make lint-templates`** — guards that no handler bypasses `SafeTemplates` by calling `.ExecuteTemplate(w, …)` directly (CSP/render discipline; see `internal/server/render.go`). `.golangci.yml` lists the findings a later change removes, one rule per finding, pinned to the function's current score and commented with the issue or #166 step that removes it. A rule that stops matching fails the lint, so the list only shrinks. ### 6. Security scanners (static, offline) A security audit runs two passes, in this order: the deterministic scanners (gosec, govulncheck, semgrep, staticcheck, gitleaks) run first and offline, and a model then triages their hits. The order is deliberate — a model adjudicating scanner output cuts semgrep's false-positive rate from about 0.42 to about 0.05 at a cost of about 3% relative recall, while a model reading code unaided over-reports. The method the audit follows is [`docs/agent-runner.md`](agent-runner.md). ### 7. End-to-end tests Exercise whole flows against a running stack. Three flavors: - **Go HTTP-level e2e** — `test/e2e/plan-management/`: an in-process `httptest` harness over the real handlers + a migrated DB (`E2E_DATABASE_URL`), with fixtures from `world` and requests from `authtest`. Runs under `go test`; covers operator plan/ladder/grant flows end-to-end at the HTTP layer. - **Go browser walkthroughs** — `test/e2e/operator-walkthroughs/`: Go tests that drive a real browser against the running stack (reads `MC_BASE_URL` from `test/.env`; set `WALKTHROUGH_HEADFUL=1` to watch). One walkthrough per operator route group, each asserting the four-bullet UI contract (empty/invalid → 422, valid → success + DOM update, …). Skips unless the stack is up and seeded. The browser tests (the walkthroughs, `test/e2e/screens` and `test/e2e/merchant-disclosure`) share `test/e2e/browsertest`, whose rules are: - **Waits are boolean predicates.** `WaitTrue`, `TryWaitTrue`, `WaitLoaded` and `WaitReady` poll a JavaScript function that returns a boolean, and a missing or destroyed execution context counts as "not yet". `Eventually` polls a Go probe that returns a boolean. golangci-lint refuses rod's `WaitLoad` and `WaitStable` (`MustWaitLoad`, `MustWaitStable`) on a page or element, with the message "wait on a predicate that returns a boolean (browsertest)". The one wait without a predicate is rod's `WaitDOMStable`, for a page that may never stop changing and is captured as it stands. - **`ClickAndLand` for an answer that is a new document** (an `HX-Redirect`, a native redirect): it anchors the wait to the new document, not to a lifecycle event. **`AwaitSwap` for an htmx swap**: it runs the action and waits for htmx to settle. - **`Recover`.** Each walkthrough defers `browsertest.Recover(t)` first, so a rod panic fails that walkthrough with its stack and the package's other walkthroughs still run. - **`AppDB`** opens the running app's database (`MC_DB_DSN` in `test/.env`), never migrates it, and skips when the key is missing. - **Free functions that take `t`**, and no helper stores it, so a subtest never calls a parent's. - **A long walkthrough is phases**: named functions, or methods on a struct that holds the walkthrough's state, called in order. - **Manual / agent-driven live loop** — the `chrome-devtools` MCP (browser on `127.0.0.1:9222`, started with `--remote-debugging-port=9222`), the Stripe MCP, and `stripe listen` webhook forwarding, for flows not yet codified — e.g. a real Stripe Checkout → `checkout.session.completed` → reconcile → the member UI reflecting the new plan. Not part of `go test`. Setup for all three lives in [`test/AGENTS.md`](../test/AGENTS.md) (worktree stack contract; the "Stripe webhook forwarding" section for the live loop). ### 8. Live DNS verification (domain claims, manual) Some of the domains registry can only be proven against a real zone: that a published challenge record activates a claim, and that publishing the challenge *prefix* with the wrong token latches `evidence_at` (exempting the claim from the abandonment ledger) without verifying. DB tests cover the branching; only real DNS covers the resolver path. You need a **disposable zone you control** — any domain whose records you can add and remove, at any registrar or DNS host with an API. Keep it separate from anything the deployment actually serves, and never commit credentials for it; supply them from the environment at the moment you use them. If the harness blocks outbound HTTP from the shell (the context-mode routing rules do), drive the DNS provider's API from a sandboxed script instead. The loop is: start a claim in the console, read its token, publish `_member-console-challenge.` as TXT, wait for a probe, assert, then delete the record. Two cases are worth proving because they diverge — a TXT carrying the challenge **prefix with a wrong token** must latch evidence *without* activating the claim, while the **correct token** must activate it. **The gotcha that will cost you ten minutes.** If the zone has a **wildcard record** (`*.example` CNAME/ALIAS/TXT), resolvers synthesise it for any challenge name that has no explicit record — so the probe reports "Found, but doesn't match" against whatever the wildcard points at, long before you did anything wrong. Publishing an explicit record stops the synthesis (RFC 4592 closest-encloser), but any cached wildcard answer still wins until its TTL expires, so probes keep reporting `mismatch` for minutes after DNS is already correct. Before concluding the prober is broken, compare authoritative against cached: ```bash dig +short @ TXT _member-console-challenge. # what the zone says dig +noall +answer TXT _member-console-challenge. # what the console sees ``` Clean up the records you added, and leave alone any challenge record that backs a claim you intend to keep verified. ### 9. OpenSpec validation (change workflow) `openspec validate ` is not a Go test but is part of the definition of done for a spec-driven change: it checks delta specs are well-formed (MODIFIED requirement headers match the main spec, every requirement has a `####` scenario, etc.). Run it before archiving a change. ## The test kit `internal/testkit` and its sub-packages hold what tests share. Each package imports only what its row allows, so any package's tests can use it without an import cycle; `internal/testkit/imports_test.go` lists the dependencies of each with `go list -deps` and fails when one reaches a package it forbids. | Package | Holds | Imports | |---|---|---| | `testkit` | `Close`, which closes an `io.Closer` and fails the test on its error | no console package | | `testkit/dbtest` | opening the test databases, scratch databases, counting the statements a request runs, `Q`, `AwaitLockWait` | `internal/db` and `internal/testkit` only (`internal/migrate` reaches nearly every package) | | `testkit/htmltest` | parsing HTML and selecting from it with CSS | no console package | | `testkit/golden` | comparing a test's output with a file under testdata, `-update` writing it, and naming the ids and times a run makes | no console package | | `testkit/world` | the fixture builder, plan and billing fixtures and the grant, tier and subscription acts included | the console's data packages; never `internal/migrate`, `internal/server`, `internal/integrations`, an integration's `web` or `workflows`, or `internal/domains` | | `testkit/authtest` | signed-in sessions, their cookies, and in-process requests | as `world` | | `integrations/fedwiki/fedwikitest` | FedWiki's fixtures and fake farm, built on `dbtest` and `world` | never `internal/migrate`, `internal/server`, or FedWiki's own module, `web` and `workflows` packages | ## Choosing what to write ``` Is the behavior a pure function of inputs? → unit test (1) Does it touch the DB / constraints / multi-table? → DB integration test (2) Does it call the Stripe API? → add a stripetest mock (3) Is it an HTTP handler / rendered page? → httptest render test (4) Is it route/template wiring or render discipline? → make lint / lint-templates (5) Is it a whole user flow (HTTP or operator UI)? → e2e (7): a test/e2e/ Go suite Is it a flow only real infra can prove (live Stripe)? → the live MCP loop (7), see test/AGENTS.md Does it depend on what a resolver actually returns? → live DNS on a zone you control (8) ``` Prefer the cheapest test that genuinely covers the behavior. Reach for an e2e suite or the live loop (7) to *prove a flow works end-to-end*, then capture the regression-proofing parts as (2)/(3) so they run in CI without a live account. ## Conventions & gotchas - **Tests meet the same complexity limit as production code.** gocognit counts a closure passed to `t.Run` toward the function that encloses it, so splitting a test into subtests does not lower its score. A test over the limit splits into named functions, runs its table rows through a named function, or uses the kit's helpers. - **Open the database through `dbtest`** (`Open`, `OpenE2E`), which skips the test when `TEST_DATABASE_URL` or `E2E_DATABASE_URL` is unset, so `go test ./...` stays green with no infrastructure. No test migrates the shared databases; `test/reset-test-db.sh` does, and `dbtest.Open` refuses one it has not. - **A test of a migration** applies it to a `dbtest.Scratch` database, never to the shared one. - **Prove a converted assertion with a deliberate break.** When a check moves onto the kit (a substring onto `htmltest`, a hand-written wait onto `browsertest`, a fixture onto `world`), apply one break that violates what the assertion says it checks, not its incidental markup, and see the test fail with that message. `scripts/mutation-check` runs a JSON list of breaks (file, exact text to replace, replacement, package, test pattern, wanted message): it runs each test unbroken first, applies one break at a time, restores the file, and reports CAUGHT, MISSED or WRONG-MESSAGE. Run it with `-side old` on a checkout of the parent commit and with `-side new` on yours, so a break the old test missed shows up as a weaker assertion. A list for browser tests carries a `prepare` command that resets and restarts the app before each break, and a command record covers a break that only the lint shows. The header of `scripts/mutation-check/main.go` gives the format. - **Don't trust webhook payloads in tests** the way production doesn't: a Stripe test should drive behavior through `stripetest.MockBackend` returning canned *API* state, not by hand-building the event payload's fields. - **No `t.Parallel()` in Stripe-mocked tests** — they share global SDK state. - **Unique fixture names** for tests that write to the shared test databases: `world` suffixes every name it writes, and `dbtest.Name` returns a unique lowercase name for the rest. `make test` resets the databases; tear the stack down with `test/teardown-stack.sh` when you want a clean slate. - **A wildcard CNAME shadows challenge lookups** — see (8). A domain-verification probe reporting `mismatch` against a record you just published is usually a cached wildcard, not a defect. - **Accumulated rows can break the browser walkthroughs.** The DB-gated suites write to `member_console_test` and `member_console_e2e` and never clean up, but `make test` resets both, and no package test writes the app database. The walkthroughs read the app database, so rows that pile up there (`core.plan_ladders`, `core.org_types`) come from the walkthroughs themselves or from manual use. Check row counts before believing a walkthrough regression. ## Lint and screens (the UI quality gate) A UX walk cannot hold the console to one shape: a page that differs from its siblings costs the walker nothing they report, so the walk's severity scale rates a consistency finding minor and triage tracks it. Sameness holds only when the build fails on it and the maintainer reviews a capture of every screen, which is what these two commands are for. - **`make lint`** runs `member-console lint`: dead routes and swap targets, retired resource keys, raw error rendering, walkthrough coverage, and the page-anatomy rules (`design-system.md` §6: raw titles, badges, and empty states outside the shared parts, `hx-confirm`, load-triggered fetches, em dashes in copy, heading skips) plus screen coverage (every GET page route in `test/e2e/screens/manifest.go`). Templates not yet rebuilt on the parts are listed in `internal/lint/anatomy_allowlist.txt`, which only shrinks; a stale entry fails. A template the lint cannot parse fails it, naming the file. `make test` runs it first; the Go checks are in (5). - **`make screens`** first restores the application database from a demo snapshot (`test/reset-app-db.sh`; the one deliberate exception to "nothing under `test/` touches `member_console`"). The snapshot is built once: migrate, `seed-demo --with-operator`, boot data state, row clocks pinned by `test/pin-timestamps.sql` to 2026-01-01 09:00 UTC plus one second per distinct original instant in the column's own order (a dense rank), so distinct instants stay distinct, each table keeps the chronology its rows were written in, and ties stay ties (the two rows one conferral act writes keep one instant, which the Tier changes fold relies on; the ledger query's id tiebreak orders inside a tie); every reset recreates the application database from it, so rows and their IDs are identical between captures and a page nobody touched never reads as changed (only relative ages tick, once a day). The snapshot rebuilds itself when the migrations, the seed, or the clock pin change (their fingerprint is the snapshot's database comment); `./reset-app-db.sh --rebuild` forces it., then captures every manifest entry at 1600×1000 and 390×844 (rod, logged in as alice for the operator surface and bob for the member surface, one incognito context each) into `test/screens/out/`, writes `operator.html` and `member.html` contact sheets in rail order, and compares each PNG with `test/screens/baseline/`, listing changed and new screens in `changes.txt` with the differing region's size and position. Parameterised routes resolve their instance from the seeded list page (the first record link, or the one a manifest entry prefers by its link text) and report "no instance" when the stack has none. `make screens-accept` promotes the output to the baseline. Both directories are gitignored; the stack in `test/.env` must be up and seeded. A change touching templates or `app.css` is not done until its sheet is reviewed (`first-contact-ux-process.md`, "Definition of done"). ## Related docs - [`test/AGENTS.md`](../test/AGENTS.md) — the test stack (ports, webhook forwarding, demo seed). - [`docs/database-management.md`](database-management.md) — migrations & sqlc. - [`docs/stripe.md`](stripe.md) — the member-console ↔ Stripe responsibility split.
