SN-1 from the twelve-domain sweep. The part worth recording up front: I caused half of it.

At the daily 40-request cap an officer read:

Tenure AI couldn't generate an answer just now, and I didn't find anything matching in your workspace.

That is a claim about their data, and it was false — retrieval had found plenty. Meanwhile the server's own sentence, the one naming the limit and when it resets, was thrown away. So the only text that explained what had happened never arrived, and every retry wrote another quota-refusal row.

Why it got worse rather than better

#247 made the chat route withdraw retrieval documents the answer never cited. That was right, and the comment I wrote at the time says so: "returning them under a refusal is exactly the defect this PR exists to remove, just reached by a different door."

But the panel keyed its no-results sentence on data.sources.length — and sources is the cited set. On a turn with no answer, withdrawing the uncited documents withdraws all of them. A correct fix turned a quota refusal into a false statement about somebody's workspace.

One number was answering two different questions:

question correct source
what may I show you? sources — the cited set
was there anything to find? retrieved — the count before withdrawal

I changed the first without checking who was reading it as the second.

The change

  • Route sends retrieved: retrievalNs.size on both response paths — not only the refusal, because an answered turn that cites nothing lands on the same client branch and should say "the answer drew on nothing", not "your workspace is empty".
  • Panel prefers the server's notice over any generic sentence. The server knows why; the client only knows that.
  • The branch moved out of the fetch handler into lib/ai/assistant-message.ts. It is a rule, not a rendering detail — and inside the handler it was reachable by no test, with the strings appearing nowhere but the source. That is why a sentence this wrong survived.
  • retrieved ?? sources.length so an older server, or a cached bundle talking to a new one, behaves exactly as before.

Proof

Seven cases, including the neighbouring branches — a quota refusal on a question that genuinely found nothing is still a quota refusal, and the aiEnabled: false arm must blame the setup rather than the workspace.

SN-1 from the twelve-domain sweep, and the part worth recording is that I caused
half of it.

At the daily 40-request cap an officer read "Tenure AI couldn't generate an
answer just now, and I didn't find anything matching in your workspace" — a
claim about THEIR data, and false: retrieval had found plenty. Meanwhile the
server's own sentence, the one naming the limit and when it resets, was
discarded, so the only text that explained what had happened never arrived. Then
every retry wrote another quota-refusal row.

WHY IT GOT WORSE RATHER THAN BETTER. #247 made the chat route withdraw retrieval
documents the answer never cited — right, and stated at the time as "returning
them under a refusal is exactly the defect this PR exists to remove". But the
panel keyed its no-results sentence on `sources.length`, and `sources` is the
CITED set. On a turn with no answer, withdrawing the uncited documents withdraws
ALL of them, so a correct fix turned a quota refusal into a false statement
about somebody's workspace. One number was answering two different questions —
"what may I show you" and "was there anything to find" — and I changed the first
without checking who was reading it as the second.

`retrieved` now answers the second, sent on BOTH response paths, and the panel
prefers the server's `notice` over any generic sentence.

The branch moved out of the fetch handler into `lib/ai/assistant-message.ts`,
because it is a rule rather than a rendering detail and because inside the
handler it was reachable by no test — the strings appeared nowhere but the
source, which is why a sentence this wrong survived. `retrieved ?? sources.length`
keeps an older server behaving exactly as before.

Seven cases, including the neighbouring branches: a quota refusal on a question
that genuinely found nothing is STILL a quota refusal, and the aiEnabled=false
arm must blame the setup rather than the workspace. Mutation-proved with md5
asserted changed and restored — keying on `sources.length` reddens 2, dropping
the notice reddens 2.

603 tests pass across the 38 AI suites; tsc 307, the baseline exactly.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to b81b5

When retrieval finds documents but the answer cites none, the panel can say that relevant items are shown even though no items appear, which may mislead users about the contents of their workspace. Merge should wait for the message and tests to be corrected.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Do not state that unavailable sources are displayed.

At Lines 45-49, retrieved > 0 with an empty sources array returns “Here are the most relevant items”. TenureAIPanel only renders items when sources.length > 0. The route withdraws uncited retrieval documents on no-answer paths, so users can see this sentence with no items below it.

Use text that says retrieval found matching documents without claiming that the panel shows them. Update the cases at apps/web/src/lib/ai/assistant-message.test.ts Lines 51-57 and Lines 66-69 to enforce that behavior.

Reviewer finding on #262, which I MERGED WITHOUT READING IT. I printed the
comment count and ran the merge in the same command, so "comments=1" reached me
after the merge had already happened. That is my own standing rule, broken for
the second time today. Fixing forward.

The finding is real, and it is the same defect I opened #262 to remove.
`assistantMessage` returned "Here are the most relevant items in your workspace:"
whenever `retrieved > 0` — but `TenureAIPanel` renders items only when `sources`
is non-empty, and uncited retrieval documents are withdrawn before the response
is sent. So a person read a promise with nothing underneath it.

TWO NUMBERS, TWO DIFFERENT QUESTIONS, AND NEITHER SUBSTITUTES:

  `sources.length` — may I promise you a list? The panel renders items only when
                     this is non-zero.
  `retrieved`      — was there anything to find? Non-zero even when every
                     document was withdrawn for being uncited.

The original bug keyed the no-results sentence on `sources.length`, so a quota
refusal claimed an empty workspace. #262 swapped in `retrieved` and traded one
false sentence for another. Both numbers are load-bearing and each answers only
its own question.

Three branches now: promise the list when there is one to render; when retrieval
found matches but nothing survived to show, say neither "here are the items" nor
"your workspace is empty"; and say the workspace is empty only when it is.

I HAD WRITTEN A TEST ASSERTING THE BUG — "offers the ranked items when retrieval
found some but none were cited" required the sentence that printed above nothing.
It now asserts the truth, and two neighbouring branches were added: the list is
promised only when `sources` is non-empty, and the same mistake one `aiEnabled`
over.

Mutation-proved with the file's md5 asserted changed and restored: putting the
promise back on `found` reddens both new cases. 9 tests; tsc 307, the baseline.

* An empty box is a claim, and six screens were making the wrong one

Six UI/UX findings from the twelve-domain sweep. They are one defect wearing six
faces: a surface with nothing on it renders a sentence that was written for a
different reason than the one that actually emptied it.

SN-2  DraftAssist branched on 503 and nothing else, so /api/ai/draft's 429 — the
      one refusal that arrives with a usable sentence attached — rendered as
      "Drafting failed. Try again." in error red. That is the single instruction
      that cannot work; the ceiling does not lift until tomorrow. 503 is very
      nearly unreachable, which is the joke: all three call sites render the
      component behind aiConfigured(), so the only status it branched on is the
      one it cannot see. It also had no catch, so a dropped connection rejected
      out of an onClick handler and put nothing at all on the screen.

SN-3  A failed /api/notifications GET hit `if (!res.ok) return`. `loaded` stayed
      false and BOTH empty-state guards were gated on it, so the render fell
      through to the list branch and drew an empty <ul> under a header still
      reading "Notifications · 3 new" — the badge is server-rendered, so the
      count kept insisting there was something there. No error, no retry, and it
      never changed, because every 30s poll failed the same silent way. The
      history overlay had the identical defect. The first paint was blank for the
      same reason and is now "Loading".

SN-43 "No matching resources — try a different search or clear the filters",
      shown beside an EMPTY search box with no chip active. The canManage arm
      half-covered it by naming publishing, so the sentence with nothing
      actionable in it was reserved for the officer who cannot publish. The
      Retired tab was wrong in the other direction and ALWAYS: the tab only
      exists while something is retired, so an empty one means the filter emptied
      it, and "Nothing retired" was false every time it rendered.

SN-44 "Start one on the right" gave a direction that was wrong twice over. Below
      `lg` the grid is one column and that card stacks BELOW this one; and both
      cards in it are conditional, so for a student with no board seat and no OSE
      role the column is empty at every width. Now it names Compose, which is
      unconditional and sits directly above. The test proves the emptiness rather
      than assuming it.

SN-45 /orgs?category=SOCIAL after the last Social club is archived: title,
      subtitle, chips, then an empty <div>. The activeClubs.length === 0 guard
      could not catch it — activeClubs was not empty, the subset was — and the
      Social chip is dropped at count 0, so no control on the page was in the
      selected state and nothing said a filter was applied.

SN-46 "Every request this club has put through the chain" silently omitted every
      cancelled one. The groupBy has no status filter, so CANCELLED rows were
      fetched and then dropped by the bucketing: no segment, no legend, and not
      in the bar's denominator. A club that withdrew two of every five requests
      drew a full green Approved bar on a page built to be shared with an advisor.

WHAT THE CONTROLS GUARD, AND WHAT THEY DELIBERATELY DO NOT

Three decision rules were extracted as pure exports — draftOutcome, panelState,
shelfEmptyState — for the reason assistantMessage was extracted in #262: inside a
fetch handler or behind component state they were reachable by no test, and that
is how each of them got its sentence wrong. renderToStaticMarkup cannot type into
a search box or fail a fetch.

The SN-46 guard reads ApprovalStatus out of schema.prisma and asserts every
member is named in the bucketing AND added into approvalTotal. Asserting CANCELLED
alone would have guarded the one case that prompted it and held the door open for
the next. Proved by adding a status to the schema: the guard goes red. It parses
the schema rather than importing the enum because the generated client here is
stale — three suites already fail on Object.values(<PrismaEnum>) for that reason.

Every fix was mutation-proven: reverting each one turns its own assertions red and
leaves the neighbours green.

Cancelled takes --warning rather than a third grey. Under
`@media (prefers-contrast: more)` globals.css points --text-3 and --border-strong
at the same value, and inside a 3px bar colour is the only thing separating one
segment from the next.

NOT DONE: NW-14. See the PR body — the defect is real in shape but unreachable at
this tree's volumes, and the prescribed fix would introduce a live bug.

* Whitespace: drop stray blank lines left by the edit pass

No behaviour change. tsc 307 (parity), jest 3 failed / 357 passed — the same
three pristine-main suites.

* Whitespace: nine more stray blanks the edit pass left inside JSDoc and JSX

The heredoc that applied each edit carried a trailing newline the anchor did not,
so every replacement site gained one blank line — some of them inside a comment
block or between a ternary's opening paren and its element. No behaviour change.

tsc 307 (parity), jest 3 failed / 357 passed / 5811 tests — the same three
pristine-main suites, no new failures.

* Tighten one assertion: match the bar's own tooltip, not a bare number

`toContain(">2</span>")` would have been satisfied by any span rendering a 2 —
a stat tile, another legend row. `title="Cancelled: 2"` pairs the label with its
count and can only come from the segment under test. Re-proved: removing the
segment still turns it red.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

* A retry button is the wrong answer to an expired session

From the independent review of this PR. `/api/notifications` answers 401
`{unread:0, items:[]}` to a tab whose cookie has expired. Both handlers
collapsed every non-ok status into one boolean, so `panelState` could not see
it and the panel rendered "Notifications could not be loaded" with a button
reading "Try again".

Pressing it re-fetches, gets 401, and calls the setter with a value that is
ALREADY set. React bails on the identical value, so the DOM does not change.
Ever. Meanwhile the 30s poll repeats the same 401 behind it.

An officer leaves a tab open overnight and meets this with the badge still
showing the server-rendered count.

`DraftAssist` sixty lines away in this same PR already had the correct arm —
"Try again would loop them through the same 401 forever" — and its test is
named "does not tell a signed-out tab to try again". So this is the house rule,
not a new one, and the bell's own docblock names 401 first.

The state now carries WHY, not merely THAT: `ReadFailure = "expired" | "error"`.
An expired session gets the sentence DraftAssist already wrote and a sign-in
link instead of a retry.

MAPPED, NOT ALIASED. The first version of this returned the failure kind
straight out of `panelState`, which typechecked as far as the render and then
did not: the FAILURE is an "error" while the PANEL STATE is "failed". Two
vocabularies that happen to be adjacent, and collapsing them is how "expired"
would quietly become another word for broken. tsc caught it at 308 against a
307 baseline.

Also from the review, and the mechanism behind the dead button: `failed` was set
on failure but never cleared on ATTEMPT, so the panel asserted a stale failure
while a fresh request was in flight — including a reopened history overlay
claiming "could not be loaded" before `loadHistory()` returned. Cleared at the
top of both handlers now. This does not weaken the deliberate last-known-good
rule, which is guarded by `loaded`, not by the failure.

`readFailure(status)` is extracted as a pure export for the same reason
`panelState` is one, and it is this file's own stated method: a decision rule
left inside a fetch handler is reachable by no test, which is how each of these
got its sentence wrong in the first place.

Proved by mutation, each killing exactly one test: collapsing expired back into
failed kills "tells an expired session to sign in"; classifying 401 as an
ordinary error kills "calls 401 expired". 41 tests pass. tsc 307, exact parity.

* A sign-in link is a Link, and CI is what says so

My own defect, and it broke three jobs on this branch.

The `SessionExpired` panel I added used `<a href="/signin">`. That is an ESLint
ERROR rather than a warning — `@next/next/no-html-link-for-pages` — so
`next build` fails, taking Lint, Container Build and the E2E build with it.
`Link` was already imported at line 4 of this file; I simply did not use it.

WHY I DID NOT CATCH IT, which is the part worth keeping. I verified with jest
and tsc — the tools I reached for — and neither runs ESLint. `next build` does,
and that is what CI runs. Verifying with the tools you happen to reach for
rather than the ones the gate uses is the same shape as the other misses today:
`npx tsc` being the wrong binary, `grep -c` exiting 1, a jest path with
parentheses matching nothing and reporting "3 passed".

Now checked with `npx next lint` on the file (clean) and across the repo: zero
error-level lint anywhere, warnings unchanged.

* A null body blamed the network, and a stale poll blamed the server

Both reviewer findings on this PR, and both turn a specific true sentence into
a wrong one — which is the failure this whole branch is about.

1. `res.json()` RESOLVES to `null` for a body that is literally `null`. It does
   not throw, so `.catch(() => ({}))` never fires, and the `as { notice?: string }`
   that followed is erased at build time. `draftOutcome` then read `.notice` off
   null and threw into the caller's outer catch — which says "Drafting failed.
   Check your connection and try again."

   So a 401 with a null body told the person their NETWORK was at fault when the
   truth was "Your session has expired. Reload the page and sign in again" — the
   one sentence that would actually have fixed it. Measured, not assumed:
   `new Response("null").json()` gives back null and throws nothing.

   Normalised at the boundary, in a named export rather than inline, so it can
   be tested: `draftBody(parsed: unknown)`. An array is excluded too — `typeof
   [] === "object"`, so a bare typeof check lets one through to be read for a
   property it cannot have.

   The existing case in this suite covers `res.json()` REJECTING and says so in
   its comment. That is a different path, and it was the only one covered.

2. `refresh` runs on mount, on a 30s interval AND on window focus, so two are in
   flight together as a matter of routine — alt-tab back while the timer fires.
   Whichever RESOLVED last wrote the state, regardless of which was ASKED last.
   An earlier poll failing after a newer one started flipped the dropdown from
   loading to "could not load" while the newer request was still on its way to
   succeeding.

   The comment on `setFailure(null)` had already reasoned about staleness in one
   direction — a failure left set makes the panel assert a stale failure while a
   fresh request is in flight. It missed the other: a stale failure ARRIVING.

   A poll counter, checked after BOTH await points, because reading the body is
   a second suspension point a newer poll can land inside. A counter rather than
   an AbortController: the older response is not worth cancelling, it is worth
   ignoring.

Three cases added: null, an array, and a real body left untouched — the last
because normalising must not discard the server's own sentence, which is the
entire reason `draftOutcome` prefers it.

Verified: jest 3 failed / 5,818 passed — the three pre-existing stale-client
suites; this suite 6 -> 9. tsc 307, exactly baseline. ESLint clean.
