Every question the refusal is forbidden to answer, answered before the attempt by satvikOS · Pull Request #242 · Tenurework/Tenure

satvikOS · 2026-08-24T18:54:56Z

What the page does now, and what it did before

Before. /signin was one narrow card carrying a form and nothing else. The
questions a person actually arrives with — am I supposed to sign in here? does
my university password work? I have a code but no password. I was told I'd have
access and I don't — were answered nowhere, and the refusal is forbidden to
answer them: it cannot distinguish "no such account" from "wrong password"
without telling an attacker which addresses exist. /signin/activate, the
second screen of the same journey, drew no institution mark at all, so the
lockup changed between two screens, and it dropped the destination a person was
originally going to.

Now. A masthead, then one plate (920px, 1000 at xl) with two columns: the
form on the left, and on the right a labelled <dl> that answers those four
questions before the attempt — including the institution's SSO, stated as a
sentence rather than a disabled control nobody can use. The tagline sits back
on the field under the plate. Below lg there is a skip link that moves
focus (not just the scroll position) to the guidance heading, and the
stacking order is form-then-guidance. /signin/activate gets the same masthead
and plate plus an "About the code" column, and callbackUrl now travels on the
link in, all four redirects out, and the link back.

The composition is arithmetic before it is taste, and the numbers are in the
file. The one that matters: on the base commit, /signin?error=1 with the
pilot form put the submit button at 972px — 172px below the bottom of an
800px screen, in the state a person reaches by getting their password wrong,
on the one control they need next. It is at 755 now.

The auth cutover in #140 was deliberately left out

#140 stays held. This branch is the redesign half only, rebuilt on
current main. The cutover half — removing dev-login so Cognito is the only
way in — is entirely absent, and it has to stay absent until Cognito holds
82 confirmed accounts, because roughly 81 pilot users have no other door today.

Nothing under src/lib/auth*, env.ts, dev-login.ts, infrastructure/,
.github/ or docs/ is in the diff. git diff --name-only origin/main...HEAD
outside src/app/signin, src/components/brand and e2e/signin* +
e2e/dev-login-gate is empty. These files are byte-identical to main:
app/signin/pilot/page.tsx, components/auth/CredentialsSignInForm.tsx,
lib/auth.ts, lib/auth/callback-url.ts, lib/auth/cognito.ts, lib/env.ts.

Every sign-in path that works today still works — the evidence

Not asserted by inspection. A second worktree was built at origin/main, both
revisions were served against the same database, and they were compared in
a real browser.

1. The control set, diffed page by page. Every <a href>, <form>,
<input>, <label> and <button>, on seven URL states, main vs branch, in
both deployment configurations:

state	result
`/signin/pilot`, `/signin/pilot?error=1`	identical set, both configs
`/signin`, `?error=1`, `?callbackUrl=…`	nothing removed; one link added (the skip link)
`/signin/activate`	the same links with `callbackUrl` appended — same destination

In the Cognito configuration — the one where the pilots' door is a link — it
is present and identical on both:
LINK /signin/pilot?callbackUrl=%2Fworkspace "Pilot access" visible=true.

2. The door opens, on a production build. next build + next start,
tenant simon-ose, Postgres seeded from this schema. dev-login-gate.spec.ts:
14/14 passed, including a real sign-in that types into the page, lands on
/dashboard, and finds "Welcome back, Maya Johnson" — a name never typed
into the form, so it can only have come from the session the passphrase
created. Also: submit from the keyboard alone (Tab, then Enter from
inside the field), which is the test that fails if the redesign ever puts the
submit button outside its <form>.

3. The negative control — the one that matters. Same build, restarted in
the #140 posture (AUTH_DEV_LOGIN=false, Cognito configured). Verified
first that the posture is real: the served /signin has no pilot form and no
pilot link. The three new tests then fail, by name:

✘ the page still offers pilot access, and it opens that person's dashboard
✘ the form submits from the keyboard alone
✘ a mistyped passphrase marks the fields, keeps the guidance, and can be retried
  Error: The sign-in page is no longer offering pilot access.
         Roughly 81 people have no other way in.

They are deliberately not wrapped in test.skip(!DEV_LOGIN_PASSPHRASE)
like the two describes above them — a guard keyed on an env var lets exactly
the change it exists to catch land green. (Measured both ways: with the
passphrase variable still set, as CI would have it, all three fail; with it
unset the third skips for its own stated reason.)

4. Coverage against future removal. signin-guidance-is-on-the-page.test.ts:253
asserts the pilot href appears exactly twice, and the untouched
pilot-access-is-its-own-page.test.ts:223 asserts the same.

What was verified, by which command

All in /private/tmp/wt-signin/apps/web unless noted; the browser work ran
against a production build in a throwaway worktree with its own Prisma
client and its own database.


`npx tsc --noEmit -p tsconfig.json` (cache deleted)	0 errors, with a positive control — a planted `const x: number = "s"` and a `db.noSuchModel` were both reported, so the compiler was genuinely reading these files
`npx eslint` (all changed files)	clean
`npx jest --ci` (full)	324 suites, 5357 passed, 1 skipped, 0 failed
`npx jest --ci src/app/signin src/components/brand`	129 passed, 8 suites
`next build`	✓ Compiled successfully, type-check passed, 14/14 static pages
5 sign-in e2e specs on `next start`	70 passed, 2 skipped, 0 failed — `dev-login-gate`, `signin-routing`, `signin-accessibility`, `signin-brand-field`, `signin-status`
overflow census, production build	72/72 clean — 9 widths × 4 routes × 2 themes, each reading guarded on `status === 200` and on the page being the one under test
fold geometry at 1280×800	all four no-notice rows of the table in `page.tsx` reproduce to the pixel on `next start`

The 2 e2e skips are /signin/activate's focus-indicator checks, which skip
because that route renders a sentence rather than a form without a valid
invitation token. Pre-existing.

One defect the review found, and the fix

At 320px — the narrowest viewport a phone still reports — /signin,
/signin?error=1 and /signin/pilot each put 38px of themselves past the
right edge, in both themes. /signin/pilot is untouched by this branch and
overflows identically on main, so the defect belongs to the shared masthead;
it mattered here because this branch gives /signin/activate that same
masthead and would have handed it the overflow too. The header wraps below
412px now — the two lockups take a line each, neither is shrunk or hidden —
and signin-brand-field.spec.ts runs the same subtraction at 320 and 360 over
all three field routes. Nothing in this repository had ever measured below 390.

What could not be verified here, and why

A successful Cognito sign-in. There is no real user pool in this
environment. What is proved is that the form reaches the real provider and
the real user lookup — the wiring, not the credential check, and no code in
this diff touches either.
A refusal during a published service window is the one state whose submit
button is still below an 800px fold. It is now measured rather than assumed:
with the same notice row on both revisions, origin/main puts the button at
972 and this puts it at 944. It runs past the fold on the composition
this replaces too, the page scrolls, and it is the case to look at first if
this composition is ever revisited. The exact pixel depends on the prose an
operator wrote, so it is a comparison and not a constant.
The e2e file assumes the dev-login-only configuration CI runs, and always
has: pointed at a Cognito-configured server, 7 pre-existing tests in it fail
alongside the 3 new ones. Measured, and unchanged by this branch.

Correcting the record

Two verification notes in signin/page.tsx were stale and understated the
work — they said a production build could not be made here. It can, and every
browser assertion above was re-run on one. The note now also carries the two
traps that cost the time: a worktree sharing this repository's node_modules
gets whichever Prisma client last ran prisma generate (if it predates
ServiceNotice the page 500s rather than failing at the query), and a
production server refuses to start with AUTH_DEV_LOGIN=true unless
ALLOW_DEV_LOGIN_IN_PRODUCTION=true says so out loud — a census run against
the 500 it returns reports zero of everything and reads exactly like a pass.

…e attempt /signin had a form and almost nothing else. It never said who is entitled to sign in, that a Tenure account is not a university login, what to do with an invitation code, or who to ask — so each of those was answered only by FAILING, and the refusal is deliberately uninformative because §14.2 forbids distinguishing "no such account" from "wrong password". The design was: withhold the explanation, then withhold it again at the moment it is most wanted. Saying it up front is also the only version that is SAFE. The refusal already discloses the process — "a member of staff proposes somebody, and the Director approves it" — precisely because it is identical for every refused address and therefore no oracle. If it is safe in the failure state it is safe at rest. WHAT CHANGED · /signin is one plate with two columns: the form on the left, and on the right a labelled region with a <dl> answering four questions — who signs in here, the institution's own SSO (a sentence, never a disabled control), "you have a code but no password yet", and "you are expecting access and do not have it". · The masthead stays. The institution's lockup is NOT repeated inside the plate: two copies of one identity 200px apart is the objection this page already records against carrying Tenure's mark twice, and `signin-status.spec.ts` locates `main h1` strictly, so a second one is a broken locator rather than a style opinion. · /signin/activate gets the same masthead, the same plate and its own guidance column ("About the code"). Its mark used to vanish on the second screen of a two-screen journey. · `callbackUrl` now travels to /signin/activate and back: on the link in, on all four redirects out, and on the link to the sign-in form. Following a link to an approval, setting a first password and being dropped at the dashboard was a real defect on the one journey where the person has never signed in here before and cannot tell a lost destination from a broken product. · A skip link reaches the guidance below `lg`, and moves FOCUS rather than just scrolling. · `ServiceNoticePanel` gains a `ground`, and the notice moves into the form column. Its brand treatment is white type on `bg-black/25`, which on a card is white on near-white. THE NUMBERS, measured in a real browser at 1280x800 dev-login, no notice plate 457px bottom 631 button 575 dev-login, notice 598 766 737 Cognito, no notice 577 745 489 Cognito, notice 577 745 657 Cognito, refused 627 795 675 dev-login, refused 616 784 755 The card this replaces was 579px with the pilot form and 557px with the Cognito one, carrying none of the guidance: the second column is paid for out of height the first was not using, because the plate is as tall as its taller column. The refusal is the one to read twice. On the commit this branches from, /signin?error=1 put the SUBMIT BUTTON at 972 — 172px below the bottom of an 800px screen, in the state a person reaches by getting their password wrong. It is at 755 now. The notice's alternatives were measured, not argued about: beside the plate wants 1704px of measure against 1240 available; stacked above it puts the plate's bottom at 929. WHAT DELIBERATELY DID NOT CHANGE This is the redesign half of #140 and none of the auth cutover. `dev-login` is untouched: the inline "Pilot access" region on /signin, the footer link and the post-refusal "Sign in with that" sentence are all still there, and `signin-guidance-is-on-the-page.test.ts` asserts each of them by name — a redesign is exactly the kind of change that removes one of those without meaning to, and ~81 pilot users have no other way in. The refusal copy is byte-identical; a crafted ?error=…&callbackUrl=… produces the same alert text as a plain one (verified in the browser). VERIFIED tsc 316 errors before and after — every one a Prisma client generated from another branch in the shared node_modules, none in a touched file. eslint clean on all nine files. jest 5353 passing; the same three suites fail on this branch and on a stash of it, for the same reason. Accessibility checked on the served page: heading order, labelled fields, focus ring, Enter-submits, the alert taking focus with both fields aria-describedby and aria-invalid, and the skip link landing focus on the guidance heading. Two e2e censuses follow the notice: `signin-brand-field.spec.ts` now asserts it is NOT on the field, and `signin-accessibility.spec.ts` names it in its own required list and publishes a window to reach it. Its two-column test measured the notice against the card, an arrangement that only existed while a notice was published; it now measures the plate's own columns, in every configuration.

Removing dev-login is a change somebody is actively proposing, and the pilot cohort has no second door until every one of them holds a Cognito account. The suite proved that door worked only INCIDENTALLY — as a side effect of two dozen specs signing in on their way to a calendar or a budget — so its removal would have surfaced as two dozen unrelated failures in files that are not about sign-in, none of which says what broke. Extends e2e/dev-login-gate.spec.ts, which already owns this gate, rather than adding a second spec with a second opinion about the same flow. Three tests, one per thing a person does at a sign-in page: - a club seat signs in through the redesigned page and the DASHBOARD opens, with their own name on it. The existing positive test admits the OSE Director, who lands on /admin — a different route and a different entitlement check, so it cannot stand in for this one. - the form submits from the keyboard alone. The redesign moved this form into a two-column plate; the failure that invites is a submit button outside the <form> it belongs to, which no other test would notice because every other sign-in in 27 spec files is a click. - a mistyped passphrase marks both fields invalid, leaves the guidance column standing, and can be retried into the dashboard. Deliberately NOT wrapped in test.skip(!DEV_LOGIN_PASSPHRASE) like the describes above it: a guard keyed on an environment variable lets the exact change it exists to catch land green, because removing the provider removes the variable with it.

Every pre-authentication route shares one masthead, and at 320px — the narrowest viewport a phone still reports — it did not fit. Measured on the served page, in both themes: /signin, /signin?error=1 and /signin/pilot each put 38px of themselves past the right edge of the document, and the thing sticking out was Tenure's own lockup. /signin/pilot is not touched by this branch and overflowed identically on origin/main, which is how you can tell the defect belonged to the masthead rather than to any one page. It mattered here because this branch gives /signin/activate that same masthead — the fix for the institution's mark vanishing on the second screen of one journey — and would have handed it the overflow along with it. The header wraps now. At 320 the institution's group is 259.5px, Tenure's is 95.7px and does not shrink, and with the gap that is 371.2px of content against 280px of measure; the three alternatives all give up something this page is not allowed to give up. Shrinking the mark means a 21px image, and the words inside a vertical lockup stop being words — the defect its size was raised to fix. Shrinking the unit name past 86.6px breaks the institution's own name mid-word. Hiding it is `hidden sm:block` again, which took the Office of Student Engagement off the page on a phone. So below 412px the two lockups take a line each and neither is touched; at 412 and above nothing moves at all. `ml-auto` is load-bearing rather than tidy: a lone item on a wrapped line is packed to the START under `justify-between`, which put Tenure directly beneath the institution's mark instead of in the corner opposite it. `signin-brand-field.spec.ts` now runs the same subtraction at 320 and 360 over all three field routes. Nothing in this repository had ever measured below 390 — `mobile-shell.spec.ts` starts there too — so a person on a 320px phone was reading a login page that slid sideways under their thumb with no test anywhere to say so. Two verification notes in signin/page.tsx were also stale and understated the work, so they are corrected against what a production build actually does: `next build` succeeds and `next start` serves, the four rows of the fold table that have no service notice reproduce to the pixel on it, and the one state that still runs past the fold — a refusal during a published service window — is now CONFIRMED rather than disclosed: measured with the same notice row on both revisions, origin/main puts the submit button at 972 and this puts it at 944. The page scrolls; it is a reach, not a lockout. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Walkthrough

The pull request redesigns sign-in and activation pages with shared branding, responsive two-column layouts, contextual service notices, guidance content, callback preservation, and expanded accessibility and access-path tests.

Changes

Sign-in and activation redesign

Layer / File(s)	Summary
Shared branding and notice rendering `apps/web/src/components/brand/ServiceNoticePanel.tsx`, `apps/web/src/components/brand/SignInMasthead.tsx`, `apps/web/src/components/brand/service-notice-panel.test.tsx`	Service notices support brand and surface contexts. The masthead wraps lockups on narrow screens and supports long institution names.
Sign-in plate and guidance flow `apps/web/src/app/signin/page.tsx`, `apps/web/src/app/signin/signin-guidance-is-on-the-page.test.ts`, `apps/web/src/app/signin/signin-surfaces-are-legible.test.ts`	The sign-in page uses a responsive form-and-guidance plate. Notices render inside the form column. Guidance, access paths, callback propagation, navigation, and contrast receive coverage.
Activation layout and callback flow `apps/web/src/app/signin/activate/page.tsx`, `apps/web/src/app/signin/activate/activation-page-is-wired.test.ts`	The activation page uses shared branding and guidance. Validated callback URLs persist across activation outcomes and return links.
Responsive and access-path regression coverage `apps/web/e2e/dev-login-gate.spec.ts`, `apps/web/e2e/signin-accessibility.spec.ts`, `apps/web/e2e/signin-brand-field.spec.ts`	E2E tests cover pilot sign-in, keyboard submission, refusal recovery, service-notice contrast, narrow-screen overflow, and two-column geometry.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: ⚪ Minimal · up to e7fc8

The sign-in redesign adds guidance and preserves existing authentication paths. A remaining test locator is coupled to JSX indentation and could create false failures after markup formatting changes, but it does not affect users at runtime; the PR is merge-ready after normal checks with a trivial follow-up.

42-48: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Make the guidance-column locator independent of source indentation.

Line 43 matches a literal newline plus 14 spaces. That string depends on the exact nesting depth of the plate in page.tsx. If a wrapper element is added or removed, or a formatter re-wraps the JSX, indexOf returns -1 and every test in this file fails through guidanceColumn(). The failure then reports a missing guidance column when the column is present and correct.

Match the attribute with flexible whitespace instead.
