All ten accessibility findings, worked in the order given. All ten were opened at the cited file:line and confirmed still present and still reachable before anything changed. Nothing was refuted — but line numbers had drifted on three, and one sub-claim was factually wrong (details below).

Every contrast figure in the findings reproduced independently, to two decimal places: 3.25:1, 11.13:1, 10.23:1, 4.18:1, 5.92:1, 6.09:1. These findings were measured carefully.


Fixed

id what a user could not do
SN-11 A refused server action was painted in Tailwind's raw text-red-700 at three call sites — 2.98:1 on the dark glass panel, 3.25:1 on the black shell rail, against a 4.5:1 floor. Those three sentences are the entire feedback channel for a refusal, since a thrown guard is redacted to a digest by the error boundary. Now --error-strong: 10.23:1 and 11.13:1. Light improves too, 6.47 → 8.01.
SN-12 Notification rows carried outline-none with nothing put back. A keyboard user tabbed a list where no row showed as focused, and Enter marked an unidentifiable notification read.
SN-13 Every spreadsheet in the workspace reached a screen reader with no column headers — a budget cell read as "18500" with nothing to say which column. The component already knew row 0 was the header; that is the condition that bolds it.
SN-14 Four <label> elements named nothing, including the one that installs the mark used to sign documents.
NW-8 The directory search announced nothing at all — not the result count, not the "No matching people." it renders — and its options had no focus indicator. An administrator could press Enter on a person they could not see they had selected and propose the wrong human for a board seat.
SN-39 The seat-status select — which decides whether someone takes a seat now or shadows the incumbent — had no accessible name.
SN-40 The CSV import preview had no header row, eight lines above the button that overwrites a club's budget.
SN-41 The backup-approver notice, the one sentence establishing whose authority is being exercised, sat at 4.18:1 in light theme.
SN-42 The AI transcript scrolled smoothly for users who had asked for reduced motion. globals.css declares scroll-behavior: auto !important under that query, but an explicit behavior argument overrides the computed property — so the stylesheet's guarantee was false at the app's only JS-driven scroll.
NW-7 Every cell of the editable budget grid was an <input> with no accessible name — announced as bare "edit text" plus its value, no column, no row. Reachable by any active contributor (editable is computed server-side from canContribute). Added after #255 merged and freed the file.

Three defects found while fixing, beyond the brief

  • The <Link> arm of the notification list is the neighbouring branch of the <button> arm. It relied on the UA default ring, so one list gave two different focus treatments. Both arms now match.
  • Selecting a person in the directory picker unmounted the focused button, dropping the keyboard user onto <body> — top of the admin page, mid-form — at the exact moment they committed to a name. Focus now follows the control that replaced the one they used, in both directions.
  • The picker's search input had no accessible name either; it had only a placeholder.

Nothing skipped

NW-7 was originally held back because DocumentViewerOverlay.tsx belonged to #255. That merged, so this branch is rebased onto af481d98 and NW-7 is included. The rebase was clean, and no fix here touches a file that #255 or #261 changed.

Two things the obvious NW-7 fix gets wrong, both handled:

  • The header row here is editable, unlike its read-only sibling — renaming a column is what this screen is for. The heading inputs stay inputs inside the <th> and carry names of their own, rather than becoming static text.
  • ri indexes sheet.rows, and updateCell writes by that absolute index. Splitting the header off shifts the body map's index by one, so dropping the +1 would silently edit the wrong row. The test names a cell by row specifically to hold that.

A user can blank a heading, which would put the cell straight back to "edit text", so columnName falls back to "Column 3".


One sub-claim was wrong, and one guard bit me

SN-14's smallest_change gives the path as settings/SignatureMarkPanel.tsx; it is components/settings/SignatureMarkPanel.tsx. Lines 115/128 were exact. SN-40 and SN-42 also cite lines that have drifted (229 → 262, 273 → 322); the defects were real at the moved locations.

fork-prevention.test.ts caught me. My first pass wrote aria-label="Search the University of Rochester directory…", adding a second tenant literal to a file allowlisted for one, on a ratchet that only turns one way. A correct catch on a genuine multi-tenancy regression; the label is now tenant-neutral and matches the visible placeholder, which is better for SC 2.5.3 anyway. Flagging it because it is exactly what an a11y PR would otherwise smuggle in.


Two guards, neither pinned to the case that prompted it

design-token-contrast.test.ts already measures every readable ink against every surface in both themes and holds them to AA. It was completely blind to all three red sites, because a component writing text-red-700 has left the token system that test parses.

  1. no-colour-escapes-the-token-system.test.ts — asserts no shipped component names a raw palette colour, in any of 16 utility families, any of 22 hues, at any of 11 shades. Pinning the three known sites would have been green forever and silent on the first text-amber-600. It carries a self-test: a scan that finds nothing is a claim about the scanner, so 14 cases prove the detector fires on real offenders and stays quiet on house tokens, arbitrary lengths, bg-black, and width utilities. A file-count floor catches a walk that silently returns [].
  2. jsx-a11y/label-has-associated-controlnext/core-web-vitals registers the plugin but enables only its aria-prop subset, which is why four unnamed labels passed lint for months. assert: "either" accepts both house patterns (htmlFor/id, and label-wraps-control) so it constrains the outcome without dictating markup.
  3. spreadsheets-name-their-columns.test.tsx — the read-only view and the editor are the same table shown twice, and they had already drifted: SN-13 fixed one, NW-7 the other. One test renders both and asserts over rendered markup rather than source text, so a refactor that keeps the output correct keeps passing. Negative controls for each checker, because an accessible-name checker that cannot fail is the thing it exists to prevent; blank-heading and empty-sheet branches tested too.
  4. --error-strong is now measured on every plate and on both glass fills composited over the base, since two of the three refusal sites sit on glass.

Both were proven by mutation, not assumed:

  • reinstating text-red-700 in ConfirmDialog.tsx → scan goes red naming ConfirmDialog.tsx:438
  • deleting one htmlFornext lint errors at ClubImageEditor.tsx:63
  • pointing --error-strong at #b91c1c → the new contrast assertion goes red
  • stripping the editor's cell aria-label → 3 spreadsheet assertions go red
  • removing scope="col" from the read-only view → 1 goes red

Each file was restored and its md5 verified back to baseline afterwards.


Second commit: the reviewer was right twice, and the E2E failure was mine

The first push went red on handoff.spec.ts:93, and it was my defect, not a flaky test. My live region restated the selection — name and email — into a screen-reader-only node, so getByText(email) resolved to two elements and Playwright refused in strict mode.

That is a real defect on its own terms, not a locator inconvenience: copying text already on screen into an sr-only node competes with the announcement the focus move produces, and it makes getByText(email) ambiguous for every test that touches this picker. The region now announces search state only — what NW-8 actually asked for. aria-label="Clear selection" is back to its value on main, byte for byte, so admin-console.spec.ts:58 need not depend on Playwright's substring-matching semantics to keep passing.

CodeRabbit found two more, both in code this branch introduced, both real:

  • "No matching people." could be announced before the first request was sent. q changes on the first keystroke while results is still empty, and loading only turned on 180 ms later inside the debounce. setLoading(true) now runs before the timeout, so the debounce window counts as searching.
  • The palette scan missed compound colour utilities. border-t-red-700 and ring-offset-red-700 are real Tailwind colour classes; a list stopping at the bare prefix would call a file clean while it painted a raw border — exactly the failure the guard exists to prevent, in the guard itself. Six new cases prove the widening both ways: it now fires on side-, axis- and logical-property borders and on ring offsets, and stays silent on border-t-2 and ring-offset-2, which are widths.

Verification

gate result
tsc --noEmit -p apps/web/tsconfig.json 307 — parity with merged main (af481d98); zero in any file I touched
jest (full) 3 suites failing — exactly the 3 that fail on pristine main (connectors/audience, nothing-manufactures-the-member-seat, identity/onboarding-form), 5811 passing
next lint no errors

next build does not complete in this worktree — it dies on admin/actions.ts:724 functionKeys, which is line 1 of my own pre-existing 307-error baseline, in a file not in this diff, caused by the stale generated Prisma client. I flagged that unverified on the first push; CI has since confirmed itLint · Type Check · Test · Build passed, so the local failure was the stale client and nothing else.

The parity number earned its keep

The typecheck went to 309 at one point. matchAll(/…/gs) passes Jest's transform happily, but the dotAll flag is rejected at this project's TS target — a green test suite and a broken build. That is exactly what the 307 baseline is for. Both are now [\s\S].

On the automated reviewers

gh pr checks reports CodeRabbit as pass, but its description is "Review rate limited" — read the description, not the bucket. The two inline comments it left are real and are addressed above; anything beyond them was not looked at. Greptile is returning a trial-credit-limit notice as a COMMENTED review across this queue. This PR should be treated as not bot-reviewed beyond those two comments.

Merge ordering

This PR touches all four files that more than one open PR claims:
TenureAIPanel.tsx (#270), BudgetUpload.tsx (#272), NotificationBell.tsx (#272, #274), approvals/[id]/page.tsx (#272). #272 contends on three of them. #269 and #272 want a deliberate order rather than whoever-goes-green-first; whichever lands second should be rebuilt onto the other.

Two behaviours deliberately held identical

  • Lifting the sheet header into <thead> changes what :nth-child sees, so the body row's odd:/even: classes swap — the zebra stripe renders exactly as before.
  • --role-brand-surface is byte-identical to --primary-light in both themes, so the approvals banner's plate does not move; only its ink darkens (light 4.18 → 5.92, dark 6.09 → 9.06).

claude added 3 commits August 25, 2026 02:50
All nine were opened at the cited file:line and confirmed reachable before
anything was changed. Every contrast figure in the source findings reproduced
to two decimal places, so the numbers below are measured, not quoted.

WHAT A USER COULD NOT DO

  · A refused server action was painted in Tailwind's raw `text-red-700` at
    three call sites. That is 2.98:1 on the dark glass panel and 3.25:1 on the
    black shell rail, under a 4.5:1 floor — and those three sentences are the
    ENTIRE feedback channel for a refusal, because a thrown guard is redacted
    to a digest by the error boundary. Now `--error-strong`: 10.23:1 and
    11.13:1.

  · Notification rows carried `outline-none` with nothing put back, so a
    keyboard user tabbed a list where no row showed as focused and Enter
    marked an unidentifiable notification read.

  · Every spreadsheet in the workspace reached a screen reader with no column
    headers: a budget cell read as "18500" with nothing to say which column.
    The component already knew row 0 was the header — that is the condition
    that bolds it.

  · Four <label> elements named nothing, including the one that installs the
    mark used to sign documents.

  · The directory picker announced nothing at all — not the result count, not
    the "No matching people." it renders — and its options had no focus
    indicator, so an administrator could press Enter on a person they could
    not see they had selected and propose the wrong human for a board seat.

  · The seat-status select, which decides whether someone takes a seat now or
    shadows the incumbent, had no accessible name.

  · The CSV import preview had no header row, eight lines above the button
    that overwrites a club's budget.

  · The backup-approver notice — the one sentence establishing whose
    authority is being exercised — sat at 4.18:1 in light theme.

  · The AI transcript scrolled smoothly for users who had asked for reduced
    motion. globals.css declares `scroll-behavior: auto !important` under
    that query, but an explicit `behavior` ARGUMENT overrides the computed
    property, so the stylesheet's guarantee was false at the app's only
    JS-driven scroll.

THREE THINGS FOUND WHILE FIXING, BEYOND THE BRIEF

  · The <Link> arm of the notification list is the neighbouring branch of the
    <button> arm and got the same indicator, so the list is uniform however a
    row was built.

  · Selecting a person in the directory picker unmounted the focused button
    and dropped the keyboard user onto <body>, at the top of the admin page,
    mid-form — at the exact moment they committed to a name. Focus now
    follows the control that replaced the one they used.

  · The picker's search input had no accessible name either.

TWO GUARDS, BOTH PROVEN TO FIRE

Neither pins the cases that prompted it. `design-token-contrast.test.ts`
already measures every readable ink against every surface in both themes and
was completely blind to all three red sites, because a component writing
`text-red-700` has left the token system that test parses. So:

  · a scan asserting NO shipped component names a raw palette colour, in any
    utility, in any hue, at any shade — with a self-test proving the detector
    still fires, since a scan that finds nothing is a claim about the scanner

  · `jsx-a11y/label-has-associated-control`, which next/core-web-vitals
    registers the plugin for but does not enable, which is why four unnamed
    labels passed lint for months

Each was verified by mutation: reinstating `text-red-700` in ConfirmDialog
turns the scan red and naming it in a label turns lint red, both restored to
the exact baseline md5 afterwards.

VERIFICATION

  tsc --noEmit   307 errors — parity with pristine main, none in touched files
  jest           3 suites failing, exactly the 3 that fail on pristine main
  next lint      no errors

Two behaviours were deliberately held identical. Lifting the sheet header into
<thead> changes what :nth-child sees, so the body's odd/even classes swap to
keep the zebra stripe as rendered; and --role-brand-surface is byte-identical
to --primary-light in both themes, so the approvals banner's plate does not
move — only its ink darkens.

Three defects, all in code this branch introduced.

THE E2E FAILURE WAS MINE, AND IT WAS THE RIGHT FAILURE

`handoff.spec.ts:93` asserts `getByText(email)` is visible. My live region
restated the selection — name AND email — into a screen-reader-only node, so
the locator resolved to two elements and Playwright refused in strict mode.

That is not a test being fussy. Copying text that is already on screen into an
sr-only node is a real defect in its own right: it competes with the
announcement the focus move already produces, and it makes `getByText(email)`
ambiguous for every test that touches this picker. The region now announces
SEARCH STATE only, which is what the finding actually asked for. The selection
is conveyed the ordinary way — the option carries a visible focus ring, and
focus lands inside the card that names who was chosen.

`aria-label="Clear selection"` is back to its value on main, unchanged, so the
`getByRole` in admin-console.spec.ts:58 does not depend on Playwright's
substring-matching semantics to keep passing.

TWO REVIEWER FINDINGS, BOTH REAL

  · The empty-result sentence could be announced before the first request had
    been sent. `q` changes on the first keystroke while `results` is still
    empty, and `loading` only turned on 180ms later inside the debounce — so
    there was a window announcing "No matching people." about a search that
    had not happened. `setLoading(true)` now runs before the timeout, so the
    debounce window counts as searching.

  · The palette scan missed compound colour utilities. `border-t-red-700` and
    `ring-offset-red-700` are both real Tailwind colour classes, and a list
    that stopped at the bare prefix would have called a file clean while it
    painted a raw border. This is exactly the failure the guard exists to
    prevent, in the guard itself.

    Six new cases prove the widening in both directions: the detector now
    fires on side-, axis- and logical-property borders and on ring offsets,
    and still stays silent on `border-t-2` and `ring-offset-2`, which are
    widths rather than colours.

VERIFICATION

  tsc --noEmit   307 — parity, unchanged
  jest           3 suites failing, the same 3 that fail on pristine main;
                 5792 passing, up 6 from the widened detector cases
  next lint      no errors

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
#255 merged and freed DocumentViewerOverlay.tsx, so the one finding this
branch had skipped is now workable. Rebased onto af481d9 first; the rebase
was clean and no fix in this branch touched a file the two merged PRs changed.

THE DEFECT, CONFIRMED AT THE MOVED LINE

Every cell of the editable grid was an <input> with no accessible name, so it
announced as bare "edit text" plus its value — no column, no row, no sheet. A
treasurer on a screen reader could not tell whether the 4300 they were about
to overwrite was Budgeted or Actual. Reachable by any active contributor:
`editable` is computed server-side from canContribute.

Row 0 becomes <th scope="col"> in a <thead>, and every data cell takes its
name from that header plus its row: "Budgeted, row 1".

TWO THINGS THE OBVIOUS FIX GETS WRONG

  · The header row here is EDITABLE, unlike its read-only sibling — renaming a
    column is a thing this screen is for. The heading inputs therefore stay
    inputs inside the <th>, and carry names of their own rather than being
    turned into static text.

  · `ri` indexes `sheet.rows`, and `updateCell` writes by that absolute index.
    Splitting the header off shifts the body map's index by one, so dropping
    the +1 would silently edit the wrong row. The offset is restored
    explicitly and the test names a cell by row to hold it.

A user can blank a heading, so an empty header would have put the cell back to
being announced as "edit text". `columnName` falls back to "Column 3".

ONE GUARD OVER BOTH SURFACES

The read-only view and the editor are the same table shown twice and they had
already drifted — SN-13 fixed one, this fixes the other. A test per component
would let the next person fix one and leave the other, so
`spreadsheets-name-their-columns.test.tsx` renders BOTH and asserts over
rendered markup rather than source text.

It carries negative controls for each checker, because an accessible-name
checker that cannot fail is the thing it exists to prevent. Proven by mutation
on both surfaces: stripping the editor's aria-label turns 3 red, removing
`scope="col"` from the read-only view turns 1 red, both restored to their
exact baseline md5.

The blank-heading and empty-sheet branches are tested too — neither is the
case that prompted the fix.

VERIFICATION

  tsc --noEmit   307 — parity. It was briefly 309: `matchAll(/…/gs)` passes
                 jest's transform but the dotAll flag is rejected at this
                 project's TS target, which is exactly what the parity number

#269 landed, and it rewrites the same four lines this branch does. Two hunks in
NotificationBell.tsx, and the conflict is entirely between:

  · #269 — adds `focus-visible:` classes to the row button, keeping
    `markOneRead(n.id)`
  · this branch — changes `markOneRead(n.id)` to `markOneRead(n)`, so an old
    notification cannot lower the badge

Neither side is a revision of the other; they are two edits to one line. Both
are kept: #269's className is the base, and this branch's call is grafted onto
it. Indentation is taken from the incoming side rather than assumed, because
guessing it is how three of four edits silently no-oped earlier in this queue.

VERIFIED THAT THE WRONG RESOLUTION FAILS LOUDLY, rather than trusting that it
would. Reverting one call to `markOneRead(n.id)` gives
`NotificationBell.tsx(233,47): error TS2345: Argument of type 'string' is not
assignable to parameter of type 'NotificationItem'` — so taking #269's side
wholesale could not have shipped quietly. That is worth knowing, because it is
the difference between a conflict that needs care and one that needs attention.

After the merge: `markOneRead(n)` 4, `markOneRead(n.id)` 0, `focus-visible` 8.
tsc 307 (exact parity). 65 tests pass across shell, finance and approvals —
both #272's badge test and #269's accessibility suites.

The other two contended files auto-merged: `approvals/[id]/page.tsx` (hunks 200+
lines apart) and `finance/BudgetUpload.tsx`.

Rebased onto merged main (00e38c5, #269) — DocumentViewerOverlay.tsx
changed on both sides and merged clean.

Three real defects from CodeRabbit, all mine, all from this PR:

1. SN-36 broke saving for every legacy document. `safeServedContentType`
   degrades any stored mimeType outside the nine-entry upload allowlist to
   an opaque type, and the editor opens plenty of those: `application/csv`,
   `application/vnd.ms-excel`, `application/json`, `application/xml` and
   every `text/*`. Requiring the bytes to match the SERVED type refused all
   of them with a 400 the person could do nothing about. The opaque type is
   now exempt — it makes no claim for the bytes to contradict, no browser
   renders it, and nosniff stops one guessing.

   I first tried to fix this by refusing markup on every row instead. That
   is wrong, and the reason is now a test: an XML document legitimately
   BEGINS WITH `<`, so an unconditional markup rule makes every XML
   document permanently unsaveable. The tripwire is in
   uploads-bytes-match-content-type.test.ts so nobody re-tightens it.

2. `flush()` re-posted rejected bytes. Closing the overlay or toggling mode
   called `doSave()` again with the identical body the server had just
   refused — a guaranteed second 400, defeating the no-retry rendering.
   A `rejectedRef` blocks the re-send; editing clears it. `dirtyRef` stays
   true, because the work genuinely is unsaved.

3. `secret()` trimmed AUTH_SECRET, which CHANGES THE KEY. Any deployment
   whose secret carries surrounding whitespace would have had every
   subscribed calendar feed silently 403 for ever. Blank still throws; the
   value returned is now raw, so signing is byte-identical to before.

Also: both documentation sites still described the superseded limiter
(ten attempts, every attempt charged). They now say thirty FAILED
attempts, and why failures are the load-bearing word.

tsc 307 (parity). jest 364 passed / 3 failed — the same three suites that
fail on pristine main.

* The sign-in form counts its attempts

Six security findings, worked in severity order. Four were real and are
fixed; two were overstated and are answered with the narrower thing that
was actually true.

SN-20 — nothing metered sign-in. Verified: `createRateLimiter` existed
and had exactly one consumer (activation), `middleware.ts` deliberately
excludes `/api/*`, and `cloudfront.tf:171` has `web_acl_id` commented out
with no `aws_wafv2_*` resource in the tree. So no counter existed at any
layer. Adds `auth/signin-rate-limit.ts` — 10 per client address and 60
per account per 15 minutes — charged by BOTH credentials providers before
they do any work, not just the `dev-login` one that prompted the finding.

SN-34 — the public activation form could write the application log.
`normalizeEmail` is `trim().toLowerCase()`, so an interior newline
survives, and the `awslogs` driver (ecs.tf:470, no multiline pattern)
emits one CloudWatch event per line. Adds `lib/log-safe.ts`, used at both
sinks in `activation-store.ts`.

SN-35 — the per-person calendar feed said `Cache-Control: public`. One
word. It was the only `public` response in the tree.

SN-36 — document save was the one write path to object storage that did
not check its bytes. Adds `bytesMatchContentType`, derived from
`ALLOWED_EXTENSIONS` rather than restated, plus a legible refusal in the
viewer so the 400 is not a mystery "Save failed".

ND-4 (partial) — `calendar-sync.ts` signed feed tokens with a repository
literal when `AUTH_SECRET` was unset. Now throws, matching
`reply-token.ts`. The revocability half is a migration and stays open.

ND-3 — refuted as filed. `@auth/core` sets `sameSite: "lax"` explicitly,
so Chrome's Lax-allowing-unsafe exemption does not apply and an ordinary
cross-site attacker is blocked. Pinned by a test instead of a comment.

OB-3 — SEC-003 appeared in two comments in one file and nowhere else.
Re-homed in ADR-0008, which is where the posture is already reviewed.

tsc 307 (parity). jest 360 passed / 3 failed — the same three suites that
fail on pristine main. 65 new tests. Every fix carries a mutation proof.

* Charge failed sign-ins, not successful ones

The limiter I added in the previous commit charged every ATTEMPT. That is
an outage, and unit tests could not see it.

The Playwright suite signs in 283 times through dev-login — 72 of them as
director@tenure.demo — serially in one process (workers: 1). Charging
attempts spent the account budget partway through a run and refused every
later sign-in as the Director, so the specs time out waiting for
/dashboard: exactly the failure e2e/support/auth.ts warns about.

The same arithmetic hits real people harder. A university NAT puts
hundreds of students behind one public address, so an address budget spent
by SUCCESSFUL sign-ins refuses a whole campus at whatever the number is.

Charging only failures is also the correct construction, and what every
account-lockout scheme does: a correct password is not evidence of an
attack, so it must not spend the evidence budget. Strictly more permissive
to legitimate use, no more permissive to guessing — guessing is failure by
definition.

  - adds a non-charging `overBudget` to the shared limiter, so the
    QUESTION can be asked without the CHARGE
  - splits the API: allowSignInAttempt asks, noteSignInFailure charges
  - one charge point per provider, after the attempt, so none of the four
    refusal branches in each can quietly become a free guess
  - raises the address budget 10 -> 30: that key is a NAT gateway as often
    as a laptop, and 10 is a number for one person

Two guards caught mistakes in this commit and both were right:

  1. every-provider-is-gated.test.ts went red when I lifted the provider
     bodies to module functions — the gate was still called, but outside
     the block that guard reads. Rather than loosen it, the bodies moved
     back inside as closures. The guard is right to be textual.
  2. then it went red again because a COMMENT I had written contained the
     literal `Credentials({`, which both guards split on, manufacturing a
     phantom third provider with no gate and no meter.

tsc 307 (parity). jest 360 passed / 3 failed — the same three suites that
fail on pristine main.

* Answer the review, and keep legacy documents saveable

Rebased onto merged main (00e38c5, #269) — DocumentViewerOverlay.tsx
changed on both sides and merged clean.

* The limiter is checked before the work and charged after it

edge-access.tf said the limiter was 'charged by both credentials providers
before they do any work'. Two different things happen at two different
times: allowSignInAttempt CHECKS without spending, and noteSignInFailure
CHARGES, only once an attempt has actually failed. Written the old way the
comment describes a limiter that would refuse a whole campus for typing
their passwords correctly, which is the design the code deliberately does
not have.

The counts in both documents were already corrected in c1f4f82 -- they read
thirty FAILED per address and sixty per account, not ten.
