Unread mail, the deny count, and three unbounded reads by satvikOS · Pull Request #273 · Tenurework/Tenure

satvikOS · 2026-08-25T06:33:19Z

Nine backend-scale findings. Six fixed, one skipped as unsafe, two skipped as not worth their risk. Every one was opened at its cited line and checked against a real PostgreSQL 16 before anything changed — and three sub-claims inside surviving findings turned out to be false, which is recorded below rather than quietly fixed around.

How this was measured

A throwaway database with the repository's own migration chain applied (prisma migrate deploy, 40 migrations), seeded to 288,000 deliveries / 96,000 participants / 300,000 audit events, VACUUM ANALYZEd so index-only scans were actually available to the planner. Indexes were created and rolled back inside one transaction so before and after came off the same pages. Buffer counts are quoted in preference to wall-clock: they do not depend on what happened to be in this machine's cache, and they are what grows as a pilot's data does.

Both migrations were checked with prisma migrate diff --from-migrations --to-schema-datamodel --exit-code → No difference detected. CI's own Migrations · Drift + Apply + Isolation check also passes.

Fixed

SN-8 — Delivery and Participant had no index any read site could use

Confirmed at the schema and again in the live database. Both models carry composite keys whose leading column is the wrong end of the question:

Participant_conversationId_userId_key         leads with the CONVERSATION
Delivery_messageId_participantId_channel_key  leads with the MESSAGE

Every unread lookup starts from the person, so neither key has a usable prefix and PostgreSQL read the whole table. Neither read carries a tenant predicate — the institution is three joins away — so this was not "this tenant's mail", it was every tenant's mail, on every dashboard render by every signed-in user. The cost is paid whether or not there is anything to report: the account measured has zero unread and still read all 288,000 rows to say so.

site	before	after
`/dashboard` unread count	Parallel Seq Scan, 6,247 buffers	50 buffers, Index Only Scan, Heap Fetches 0
`/messages` groupBy	Parallel Seq Scan, 6,219 buffers	50 buffers, Heap Fetches 0
opening a conversation (`updateMany`)	Seq Scan on a write path	3 buffers

The third site is not in the finding and is the one I would call worst. messages/[id]/page.tsx:107 runs updateMany({ where: { participantId, readAt: null } }) on every conversation open — a full table scan to mark mail read. It is answered by exactly the same index, in exactly the column order chosen (equality first, filter second). The same index also backs Delivery_participantId_fkey: PostgreSQL does not index the referencing side of a foreign key, so until now deleting one Participant scanned all of Delivery.

workspace-reach.ts runs the same shape and is held by #261 — it needs no edit, the fix is in the schema.

SN-22 — one pass over /admin/audit

Three sub-claims. One is a large real win, two are false.

Real: the deny count had no index and read the tenant's whole audit history, testing outcome row by row. @@index([institutionId, outcome]) → 7,235 buffers / 7.797 ms → 5 buffers / 0.078 ms, Index Only Scan, Heap Fetches 0.

False — "0.66 ms with equals on an index that already exists". There is no reachable index. resourceId equality sits in an OR with three ILIKE arms, so PostgreSQL cannot build a BitmapOr and evaluates the whole predicate as a filter over the tenant's rows. Measured: 7,235 buffers before and after, 28.5 ms → 19.9 ms. Real, but a per-row comparison saving, not a hundredfold one. ([resourceType, resourceId] also leads with the wrong column.)

False — "the sibling unfiltered total seq-scans too". On a vacuumed table it is already an Index Only Scan using AuditEvent_institutionId_occurredAt_idx, 105 buffers, 0.917 ms, Heap Fetches 0. Measured before believing it, so no third index was added to fix something that was not broken.

Declined — the 90-day floor on the free-text arms. Silently time-boxing a search on an audit log means an auditor looking for something from six months ago gets "No matching events" with nothing saying the search was bounded. That is the same class of defect as the truncation this PR fixes, not a fix for it.

Real, and it took two goes to get right. The resourceId arm is now startsWith. exceptions/register.ts:121 writes the whole dedupeKey into resourceId, so an anchored match is what the evidence link means.

I first wrote it as equals, which is a bug, and writing the test is what found it. q is .slice(0, 80) four lines above. The longest class in exceptions/taxonomy.ts is INTEGRATION_ERROR:INTEGRATION_INSTALL_RESPONSE_INCOMPLETE — 58 characters before the subject begins — so a key with an ordinary 25-character cuid subject is 83 characters and arrives already truncated. equals on a truncated key matches nothing, which would have restored the exact dead end the arm's own comment warns about, for the long-code classes most worth investigating. startsWith is correct whether or not the cap bit. It does not claim to be exact — a prefix can still collide with a longer key — but contains had that same collision and matched mid-string, so this is strictly narrower than what was there before, and the comment says so rather than overclaiming.

The table now admits its cap. The heading said "every allow and every deny across the institution" above the newest 200 with nothing marking the edge. On an audit log that is the worst kind of wrong: the surface whose whole job is to be the record was answering "that never happened" for anything older. The notice fires only when the cap was actually reached, and the filtered and unfiltered cases say different things — a filtered view does not know its own total, and printing "200 of 300,000" under a search for one exception would be a bigger lie than printing nothing.

SN-25 — the reminder pass re-read the roster per stalled approval

Confirmed: owedBy is called inside the paging loop, up to MAX_PER_INSTITUTION = 5,000 times, and the pass writes only ApprovalReminder and notifications — never InstitutionMembership or RoleAssignment.

The suggested fix cannot be written as stated: remindStalledApprovals never receives an institutionId, so there is nothing to hoist above the loop. Memoised per pass and per scope instead — staff are an institution's, presidents are a club's — which also covers the PENDING_PRESIDENT branch the finding left out.

Four tests added, and both mutations proven to fail them:

remove the memo lookup → 3 of 4 fail
keep the memo but drop the club from its key → the cross-club test fails alone

The db mock now honours organizationId on roleAssignment.findMany, because a mock returning one fixture for every club makes a memo that mixes two clubs' presidents look identical to one that does not. That is the failure worth catching here — well above the round-trip count.

SN-27 — the documents page

The live list had no take and no select: every column of every non-archived document, objectKey — the raw S3 key the schema says beside itself never to hand out — included. Nothing leaked it, because the row is destructured field by field; but "the query does not fetch it" is a guarantee and "no current call site passes it on" is a habit.

Bounded, narrowed to the seven columns rendered, and both lists now say when truncated. The suggested "surface the same see-all affordance" had nothing to match — the archived list was capped at 50 and silent too.

One deliberate asymmetry: the live notice says search for it by name, the archived notice does not. loadSearchCorpus indexes isArchived: false only, so pointing somebody at a search that must come back empty would be worse than saying nothing. And the archived notice names no number: the list is filtered to what the viewer may restore, so "the 50 most recently archived" would be false above three rows.

SN-28 — tenant packs

The cache half is done: /approvals calls loadApprovalThresholds(id) and loadElevatedApprovalThresholdCents(id), and the second delegates to the first, so the identical query went to PostgreSQL twice per render. Cached per request, the same way getUserContext and resolveTenantScope already are.

Two traps avoided, both of which would have made the fix a no-op or worse: loadPack is generic and cache() does not carry a type parameter through, and its at argument defaults to new Date() — a fresh object on every call, so a cache keyed on it would never hit once and would read as though it did. The cached function takes (institutionId, kind) only.

The verify half is refuted: the finding asks to move verify after selectEffective, but selectEffective reads pack.effectiveFrom and pack.effectiveTo — it requires the parse. Only the SHA-256 could move, "fall through on failure" would need selectEffective to return a ranked list rather than one pack, and the finding's own note says a tenant has ~1 version per kind today. That is a refactor of a tamper-evidence control for a saving that is currently zero.

Skipped, with reasons

SN-26 — seat meter read twice per render — the suggested fix is unsafe, and so is the obvious alternative

The two calls do not share a bound in general. meteredQuantityToDate reads to elapsedPortion(period, at).end = min(period.end, at); reconcileSeatMeter reads to at. They coincide only while at <= period.end, which is true on this page and false for any past period — so the suggested single shared facts array is correct here by accident.

Caching instead is worse. seat-meter.itest.ts:525 and :527 call meteredQuantity(SEPTEMBER) — the same bound — inside two different tenant scopes and expect 0 and then 1. readSeatMeterFacts carries no institutionId predicate; it relies entirely on the tenancy extension. A cache keyed on the bound would hand tenant A's meter reading to tenant B, on a billing path, and the existing tests document that exact call pattern.

The finding's own note calls this "genuine waste on a small table", tenant-scoped, index-served and Director-gated. One extra query on a small table is a much better outcome than a stale or cross-tenant invoice.

NW-6 — the command palette loads the whole corpus — real, but not this fix

The problem is real. The suggested fix is not correct as written, for three separate reasons:

The query cannot go into contains whole. rankDocs tokenizes; a twelve-character multi-word query matched as one substring finds nothing. The predicate has to be an OR over tokens.
body is not a column for three of the four models — memory's is a JSON path, approval's is synthesised (${description} status:${status}), event's concatenates description and venue. A contains on one column each would silently change what is searchable.
take: 200 per model drops real matches, because there is no relevance ordering in SQL to take the top 200 of.

I checked one thing I expected to be a hard blocker and it is not: I assumed Prisma could not do a case-insensitive JSON string_contains, and JsonFilterBase in 6.19.3 does expose mode. Recording that because it was my hypothesis, not the finding's, and it was wrong.

What survives as the genuine obstacle is subtler and is the file's central design: termWeights measures IDF over the corpus being searched. Prefiltering shrinks that corpus, so weights change and ranking order shifts. The result set is provably preserved — a term with zero document frequency globally still has zero after an OR-of-terms prefilter, so the same terms are neutralised and the same rows score above zero — but the order is what a search feature is. That is a search-quality judgement to make against a real corpus, not a change to slip into an indexing PR.

NW-13 / NW-16 — both already downgraded, and both fixes have a defect

NW-13: the query is already select: { occurredAt: true } and already date-bounded by activitySince. What is left is the suggested cache — and unstable_cache "keyed by institution" is wrong for this query, whose where is organizationId: { in: orgIds }, the viewer's own clubs. Keyed by institution it would serve one officer's club set to another.

NW-16: the note is right that the fix does not remove the scans it implies, and I confirmed why: MemoryRecord has no institutionId-leading index ([organizationId, type, isArchived], [roleId], [replicatedFromId]) and ApprovalStep has only [approvalId]. A createdAt bound filters more rows earlier but reaches no index. The finding also flags that the pending tile is deliberately all-time, so a naive date bound breaks it. The real fix is an index plus a date predicate together — worth doing, and the missing MemoryRecord index is the concrete lead — but it is its own piece of work, not a line here.

Verification

Typecheck: 307 errors, the documented parity baseline. Compared by file(line,col): errorcode rather than by message text — 247 unique identities, identical sets; the only diffs are line-number shifts inside files this PR edits. Zero new type errors.
Jest: 3 failed, 351 passed, 354 total / 5,789 tests passing on the merged head. The three are the documented pre-existing failures (connectors/audience, nothing-manufactures-the-member-seat, identity/onboarding-form — Object.values(<PrismaEnum>) against the stale generated client). Nothing newly broken.
Mutation proof: every claim above about a test was checked by mutating against an anchor asserted to exist, verifying the file's md5 actually changed, running, restoring, and verifying the md5 back. Four mutations across two files, each killing the tests it should and no more.
The combination, not just the change. A key holds one version's bytes, forever #255 and then The assistant answers from the same shelf the page shows #261 both landed while this branch was open. Two individually-green PRs can red main together and CI cannot see the combination, so origin/main was merged in here twice and rechecked each time — tsc 307 both times, jest green both times. Branch is 0 commits behind main.
- The assistant answers from the same shelf the page shows #261 is the one worth naming: it edits workspace-reach.ts, the file this PR says its index reaches "for free". After its merge that file still runs the identical delivery.groupBy({ where: { readAt: null, participant: { userId, conversationId: { in } } } }), so the claim was re-checked against their code rather than left standing on the version I read.
- Final counts on the merged head: tsc 307, jest 3 failed / 351 passed, 5,789 tests passing — up eleven from the branch baseline: three are A key holds one version's bytes, forever #255's tests, four are The assistant answers from the same shelf the page shows #261's, four are this branch's own new evidence-link controls.
Throwaway databases were created for this work and dropped afterwards; no existing database was touched. prisma generate was never run, so the shared client is unchanged.

Files, against the open-PR hold list

None of the eight files touched is held. An overlap scan of my changed files against every open PR (not only the ones I was warned about) returns no conflicts. documents/page.tsx is adjacent to #255 but not in it. workspace-reach.ts (#261) and handlers.ts (#257) run affected query shapes and were read but not edited — SN-8's fix is in the schema and reaches them for free.

Summary by CodeRabbit

Improvements
- Audit searches now match resource IDs more accurately and provide clearer notices when older events are not shown.
- Document listings indicate when additional results exist beyond the displayed limits.
- Search results link directly to the selected document.
- Approval reminders reduce repeated roster lookups while preserving correct recipients.
Performance
- Improved responsiveness for unread mail, audit-event counts, document access, and tenant configuration loading.

Six backend-scale findings, each opened at the cited line and confirmed against a real PostgreSQL 16 before anything was changed. Two were measured and fixed with indexes, three were bounded, and two sub-claims inside the findings turned out to be false and are recorded as such. SN-8 — Delivery and Participant had no index any read site could use. Both models carried composite keys whose LEADING column is the wrong end of the question: Participant leads with the conversation, Delivery with the message, and every unread lookup starts from the PERSON. Neither read carries a tenant predicate, so /dashboard scanned every institution's mail on every render by every signed-in user. Measured on 288,000 deliveries: 6,247 buffers -> 50, Index Only Scan with Heap Fetches 0. The same absence also left the Delivery_participantId_fkey cascade unindexed, so deleting one participant scanned the whole table. SN-22 — the deny count on /admin/audit read the tenant's entire audit history and tested outcome row by row: 7,235 buffers -> 5. The evidence link from /admin/exceptions now matches resourceId exactly, which is what the link means, and the table says when it is showing only its newest 200 instead of describing itself as the complete record. SN-25 — the nightly reminder pass asked the roster who was owed an answer once per stalled request, up to 5,000 times, for a list the pass cannot change. Memoised per pass and per scope, with a test that fails both when the memo is removed and when it stops distinguishing clubs. SN-27 — the live documents list had no take and no select, so every column of every document was read, objectKey included. Bounded, narrowed to the seven columns rendered, and both lists now say when they are truncated. SN-28 — /approvals read the same tenant pack twice per render. The row read is now cache()d per request; verification is deliberately not. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

📝 Walkthrough

Walkthrough

The changes add Prisma indexes, bound document and audit queries, refine audit search matching, memoize approval reminder rosters per page, link search results to document viewers, and cache tenant pack rows per request.

Changes

Database lookup indexes

Layer / File(s)	Summary
Add lookup indexes `apps/web/prisma/schema.prisma`, `apps/web/prisma/migrations/.../migration.sql`	The schema and migrations add indexes for participant lookup, unread deliveries, participant cleanup, and denied audit-event counts.

Audit query bounds and search

Layer / File(s)	Summary
Bound audit search and paging `apps/web/src/app/(app)/admin/audit/page.tsx`, `apps/web/src/app/(app)/admin/audit/page.test.tsx`	The audit page uses shared limits, anchored case-insensitive resource matching, extra-row pagination, capped-result notices, and predicate-focused tests.

Document listing and search links

Layer / File(s)	Summary
Bound document lists `apps/web/src/app/(app)/orgs/[slug]/documents/page.tsx`, `apps/web/src/lib/__tests__/a-full-page-is-not-a-truncated-one.test.ts`	Live and archived document queries use bounded results and selected fields. The page reports omitted rows only when an extra row exists. A source test checks pagination truncation patterns.
Link search results to viewers `apps/web/src/lib/search-data.ts`	Document search results link directly to the document viewer.

Approval reminder roster memoization

Layer / File(s)	Summary
Memoize scoped reminder rosters `apps/web/src/lib/approval-reminders.ts`, `apps/web/src/lib/approval-reminders.test.ts`	Reminder pages cache organization president and institution staff lookups by scope. Tests cover isolation, reuse, page re-reads, and requester reminders.

Tenant pack request caching

Layer / File(s)	Summary
Cache tenant pack rows `apps/web/src/lib/tenant/packs/loader.ts`	Tenant pack rows are cached per request and pack scope. Parsing and digest verification remain uncached.

The resourceId arm was changed to `equals` earlier in this branch, on the argument that /admin/exceptions links the WHOLE dedupe key and an exact match is what the link means. The first half of that is true. The second half ignored the line four above it: `q` is `.slice(0, 80)`. `exceptions/taxonomy.ts`'s longest class is INTEGRATION_ERROR:INTEGRATION_INSTALL_RESPONSE_INCOMPLETE — 58 characters before the subject begins — so a key whose subject is an ordinary 25-character cuid is 83 characters and arrives at the query already truncated. `equals` on a truncated key matches nothing, so the change would have restored the exact dead end its own comment describes, for the long-code classes most likely to be worth investigating. `startsWith` is correct either way: it matches the stored row from its prefix when the cap bit, and is an anchored exact-prefix match when it did not. It does not claim to be exact — a prefix can still collide with a longer key — but `contains` had that collision too AND matched mid-string, so this is strictly narrower than what was there before. Four tests, and both neighbouring forms fail them: the `equals` version this replaces and the original `contains`. The db mock now captures the `where` so the assertion is about the predicate rather than about the markup, and the truncation test asserts the property that matters — that the full key starts with what the page asked for.

…type Two findings from an independent review of this PR, both confirmed at a19d227 before anything was changed. THE DOCUMENTS LIST NOW TELLS A READER to search for a document by name to open one that is past the cap — and `search-data.ts` projected a document's href as `/orgs/<slug>/documents`, the capped page itself. So search found the title, the reader clicked, and landed back on the page that had just told them it was not listed. The escape hatch led to the room it was an escape from. It now mints `/orgs/<slug>/documents/<id>/view`, which is the app's own "Open full page" action (DocumentRow.tsx:83). The id comes off a row this function has already read, so it is a DERIVED path rather than one anybody typed, which is what makes it safe to mint at all. THE `resourceId` ARM QUIETLY STOPPED BEING CASE-INSENSITIVE while its three siblings kept `mode: "insensitive"`. The long note above it argues `startsWith` over `equals` and over `contains` and never mentions case, so this was a second narrowing nothing declared. It is not free. `dedupeKeyFor` LOWER-CASES every exception key it writes (taxonomy.ts:127), while /admin/exceptions DISPLAYS the class upper-cased. The operator who types rather than clicks — the one this arm exists for, since the link already worked — pastes `INTEGRATION_ERROR:…` and gets nothing at all. Not fewer rows: none. Restoring it costs only the per-row comparison that note already measured (19.9 ms -> 28.5 ms), because as it says plainly, this arm reaches no index in either form: the siblings are ILIKE, so PostgreSQL cannot build a BitmapOr and filters the institution's rows either way. Correctness for 8.6 ms of a scan that happens regardless. Every fixture in that block was already lower-cased — as its own note says the real keys are — which is exactly why a case-sensitive arm passed them. The new test pastes the upper-cased text the console actually shows. Verified against the case-sensitive version: 3 of 12 fail, including that one. tsc 307 (parity). 12 audit tests, 26 search tests.

Both findings from the independent review are fixed in 589ee20f. Confirmed at a19d2276 before changing anything, since the reviewer's own headline finding on a sibling PR turned out to be scoped to a rebased-away commit.

1. The escape hatch led back into the room. This PR caps the documents list and tells the reader to search for one by name — and search-data.ts:105 projected a document's href as /orgs/<slug>/documents, the capped page itself. Search found the title, the click landed back on the page that had just said it was not listed. Now /orgs/<slug>/documents/<id>/view, the app's own "Open full page" action (DocumentRow.tsx:83). The id comes off a row the function has already read, so it is a derived path rather than one anybody typed — which is what makes it safe to mint at all.

2. The resourceId arm quietly stopped being case-insensitive, while its three siblings kept mode: "insensitive". The long note above it argues startsWith over equals and over contains and never mentions case, so this was a second narrowing nothing declared.

It is not cosmetic. dedupeKeyFor lower-cases every exception key it writes (taxonomy.ts:127), while /admin/exceptions displays the class upper-cased. The operator who types rather than clicks — the one this arm exists for, since the link already worked — pastes INTEGRATION_ERROR:… and gets nothing at all. Not fewer rows: none.

On the cost, which is where I disagree slightly with the review's framing. The reviewer read the 28.5 → 19.9 ms as "substantially ILIKE→LIKE, not the anchoring the comment credits". The comment already says that, and more precisely: "this does not reach an index… PostgreSQL cannot build a BitmapOr and evaluates the whole OR as a filter either way — 7,235 buffers before and after. What it buys is the per-row comparison." So restoring mode costs 8.6 ms of a scan that happens regardless, and buys back a query that returns the right rows. That trade is not close.

Why the existing tests did not catch it: every fixture in that block is already lower-cased, as the block's own note says the real keys are. A case-sensitive arm passes all of them. The new test pastes the upper-cased text the console actually shows.

Verified rather than asserted: against the case-sensitive version, 3 of 12 audit tests fail, including the new one. tsc 307 (parity), 12 audit tests, 26 search tests.

Two things left from that review that I have not done, deliberately:

events.length === PAGE_SIZE and the two document-count comparisons are false-positive at exactly the cap — the mirror of the bug the audit page's own comment promises not to commit. take: LIMIT + 1 then slice is the fix. Real, and worth its own change rather than being folded into a PR that is already green.
The reminder-memo clock: presidentsOf's comment claims requestClock() is cache()d so a pass shares one instant, but the job is a route handler, and rbac.ts:109-120 records the measured opposite. The pass already threads an explicit now. That is a real inconsistency and also its own change.

Filed rather than silently dropped.

events and truncated so it fetches PAGE_SIZE + 1 rows, sets truncated only when
an extra row exists, and renders or passes onward only the first PAGE_SIZE
events.

Apply the same fix in `@apps/web/src/app/`(app)/orgs/[slug]/documents/page.tsx
around lines 95 - 101: The live and archived document notices use the same
exact-limit detection pattern.

In `@apps/web/src/lib/approval-reminders.ts`:
- Around line 170-181: Remove the shared roster memoization around the approval
audience lookup so each approval independently calls presidentsOf or staffOf
with the current organization or institution identifier; do not reuse cached
results across approvals unless a versioned snapshot is revalidated before
claiming and notifying.

In `@apps/web/src/lib/tenant/packs/loader.ts`:
- Around line 181-192: Replace the React cache wrapper around packRows with
request-scoped memoization that works when called from route handlers, while
preserving the existing institutionId/kind inputs, query ordering, selected
fields, and return type. Ensure repeated packRows calls within one request reuse
the same database result without sharing data across requests.

Reviewer finding, and it was in three places at once: the audit log and both halves of a club's document list. `take: LIMIT` with a notice keyed on `length === LIMIT` reads a full page as proof that rows were left behind. It is not. When the filter matches exactly LIMIT rows, every one of them is on screen and the notice says otherwise. The audit page is the worst place for it. That screen's whole job is to be an accurate record, and the notice is a claim about the record's COMPLETENESS — so an institution with exactly PAGE_SIZE matching events was told some had been omitted when none had. WHY A ROW AND NOT A COUNT. The comment this replaces had already weighed `===` against a second COUNT over the same filter and kept `===`, because on the free-text arms that COUNT is the identical scan run twice. That objection is correct and I am not overruling it — the OPTION SET was incomplete. Asking for `take: LIMIT + 1` and slicing settles the same question for the price of one row: no second query, no second scan, and the answer is a fact rather than an inference. The extra row exists or it does not. Held by a claim about the SHAPE rather than these three lines, so the next list to be capped is covered on the day it is written: lib/__tests__/a-full-page-is-not-a-truncated-one.test.ts forbids pairing `length === LIMIT` with a `take` of that same LIMIT. It does not forbid `length === LIMIT` in general, and `take: LIMIT + 1` is explicitly not flagged — a control that failed on the corrected form would be worse than none. Three cases: the real tree, a positive control proving the pattern still matches the shape as it was written, and the corrected form proving it does not fire on the fix. Mutation-proved: restoring the audit page's `=== PAGE_SIZE` lists `app/(app)/admin/audit/page.tsx (PAGE_SIZE)`. Verified: jest 3 failed / 6,079 passed — the three pre-existing stale-client suites. tsc 307, exactly baseline. ESLint clean apart from one PRE-EXISTING warning: `UPLOAD_ACCEPT_ATTRIBUTE` is imported and unused at documents/page.tsx:2. It appears zero times in this diff and is present on the branch before it, so it is observed and left alone rather than folded into a commit about truncation. Two findings remain open on this PR: approval-reminders.ts:181 caches a roster that can change mid-pass, and loader.ts:192 relies on React `cache()` for dedup in a route handler, which is not a Server Component context.

approval-reminders: the memo this PR added lived as long as the pass. A role assignment revoked while the pass was running would then keep addressing the person who lost it for every remaining approval, and staffOf is keyed by institution alone -- so in a single-tenant deployment that is ONE answer held for the whole run. Moved it inside the paging loop. The saving is essentially untouched, because the saving was never across pages: at PAGE_SIZE 500 it is 500 reads becoming 1 either way, and the difference between the two placements is one read per page (at most ten, given MAX_PER_INSTITUTION). What changes is that the staleness now has a stated bound. It does not close the race and the comment says so: the reads are not in a transaction that pins a snapshot, so a revocation landing between the read and the notify is missed at any scope. packs/loader: the comment claimed `cache()` is "per REQUEST". It is per RENDER. React 19 reads ReactSharedInternals.A and calls straight through when there is none, and app-route/module.js runs a handler inside Next's own storages without setting React's -- verified against the installed next 15.5.20 and react 19.2.7. The named route is unaffected because it asks for two different pack kinds once each, so there is nothing there to deduplicate; the comment is for the caller that does not exist yet. Mutation-proved: hoisting the memo back to pass scope fails exactly the new page-boundary case and nothing else.

How this was measured

Fixed

SN-8 — Delivery and Participant had no index any read site could use

SN-22 — one pass over /admin/audit

SN-25 — the reminder pass re-read the roster per stalled approval

SN-27 — the documents page

SN-28 — tenant packs

Skipped, with reasons

SN-26 — seat meter read twice per render — the suggested fix is unsafe, and so is the obvious alternative

NW-6 — the command palette loads the whole corpus — real, but not this fix

NW-13 / NW-16 — both already downgraded, and both fixes have a defect

Verification

Files, against the open-PR hold list
