Staging /team/analytics reported 331 bookings, GMV ₹3,24,472, Collected ₹0 — with ₹0 collected on every service line — while scripts/staging-seed.sql holds a captured payment for each of those bookings. That number was wrong, not empty.

Root cause

D1 caps a query at 100 bound parameters. lib/company-analytics.ts:6 built WHERE booking_id IN (?,?,…) from the booking result set — 331 placeholders — and safeAll swallowed the refusal and returned []. GMV (no IN clause) computed fine, so the screen showed a confident zero next to a correct total. The CX ticket read in the same call was lost the same way.

The shape passes every fixture and every young environment, then breaks at exactly 101 rows. It was a class, not a query:

Read Where Fed from
booking payments + CX tickets lib/company-analytics.ts:6 every booking in the period (the live defect)
booking invoices + payments lib/accounts-business-view.ts:46 every booking in the ledger
grooming subscriptions + signup dates lib/customer-business-view.ts:28 every customer in the view
grooming cost attribution lib/grooming-cost-attribution.ts:28 every booking costed
customer names on the job feed lib/partner-job-feed.ts:71 every customer in the feed
coupons, points, wallet, payouts, refunds, reviews, tickets, LTV lib/unit-economics.ts:34,86 every booking / active customer
payroll approval + incentive events lib/people-reports.ts:29 every run and result in range
manager roster lib/manager-dashboard.ts:37 every employee under a manager

Fix

lib/d1-chunked-in.tschunkedIn(ids, read) splits the ids into chunks that fit inside the cap, runs the caller's own SQL per chunk and concatenates, so the result is identical to the query it replaces. All nine call sites route through it. A sweep test fails if any library builds an IN list from a result set again; the eight files whose lists are fixed vocabularies or per-row (literal statuses, one policy's service codes, one stay's pet ids, the months of a financial year) are listed with the reason they are exempt.

The blank screens

/team/marketing and /team/performance are blank for want of data, not function — the marketing module is fully wired (create → approve → snapshot audience → activate → attribution), there has simply never been a campaign, and no rep has ever been mapped to the sales team.

scripts/uat-demo-seed-gen.mjsscripts/uat-demo-seed.sql (deterministic, INSERT OR IGNORE, layered on the existing staging seed, documented in docs/STAGING_DEPLOY.md):

  • Sales: 4 reps as active platform users, mapped to sales; 27 leads with assignments, first-response SLA clocks (some met, some breached), recorded calls and WhatsApp touches with real outcomes, conversions linked to the seeded bookings, collected and refunded revenue events, and an active productivity policy. One click on Generate 30-day report turns it into a ranked leaderboard.
  • Marketing: a live campaign with its audience snapshot — 74 members split into eligible / holdout / suppressed, every suppression naming its reason — plus one campaign sitting at the approval gate, and ad-spend rows so the unit-economics CAC line has something real to divide by.

Table shapes are copied verbatim from the module that owns each table, and the seed is proven by executing the real modules over it: the fact run produces four reps with non-zero leads, actions, qualified outcomes, conversions and net-of-refund revenue, and the board ranks them 1–4 by name.

Tests

  • tests/d1-in-clause-fanout.test.mjs (6) — a D1 shim that enforces the 100-parameter cap, so these fail the way production did; 150 bookings with captured payments; analytics reports full GMV and full collected; accounts ledger rows carry their payment status past the first chunk; chunk semantics (ordering, empty list, per-chunk placeholders); the sweep.
  • tests/uat-demo-seed.test.mjs (5) — loads both seed files into a real database, re-runs the demo seed to prove idempotency, generates the fact run and asserts real per-rep numbers with net = collected − refunds, checks the campaign/snapshot/holdout/suppression-reason invariants, and pins the generator as deterministic.

Note for the merge order

snapshotCampaignAudience calls buildCustomer360, which on main still issues 8 queries per customer and will exceed the Workers subrequest limit on staging's 176 customers. That fix is PR #152 (unmerged) — the marketing snapshot button needs it before it will run against a full database.

…e empty screens

/team/analytics showed 331 bookings and GMV of Rs 3,24,472 next to "Collected
Rs 0" on every service line, while the database held a captured payment for
each of those bookings. D1 caps a query at 100 bound parameters, the payments
read asked for 331, and the swallow-and-continue helper around it turned the
refusal into a confident zero. The CX read in the same call was lost the same
way. It was a whole class of read, not one query: booking payments and
invoices behind the accounts view, customer subscriptions and signup dates,
grooming cost attribution, partner job feed names, the seven per-booking money
components of unit economics, payroll approval events, and the manager
dashboard roster.

Every IN-list read over an unbounded set now goes through chunkedIn, which
splits the ids into chunks that fit inside the cap and concatenates the
results, so the answer is the one the single query was meant to give. A sweep
test fails if a library builds an IN list from a result set again; lists that
cannot grow past the cap are named with the reason they are exempt.

The team screens were also blank on staging for want of data rather than
function: no reps are mapped to the sales team, and no campaign has ever been
created. scripts/uat-demo-seed.sql adds both - a sales team with lead work,
SLA clocks, recorded calls, conversions into the seeded bookings and an active
productivity policy, plus a live campaign with its audience snapshot, holdout
and ad spend. It layers on the existing staging seed, is idempotent, and is
proven by executing the real modules over it rather than by counting rows.

main fixed two instances of this class while this branch was open - the
Customer 360 fan-out (#160, corrected to a chunk of 80 by #166) and the
per-booking reads in unit economics (#165, at a chunk of 50). Both declared
their own constant in their own module, which is how the same bug came back at
a different size in a different place, and neither touched the read that is
actually wrong on staging: /team/analytics still counts 331 bookings of GMV
next to Rs 0 collected.

Both now go through lib/d1-chunked-in, so there is one helper and one size (80,
the number #166 measured: a chunk of 50 cost 82 D1 calls for 500 customers
where 58 would do). A test fails if any module declares its own chunk constant
again.

tests/crm-stack-hardening.test.mjs loads lib/customer-360.ts directly without
the extensionless-import fallback the other real-execution suites install, so
it broke the moment that module imported a sibling. It installs the same hook
now.

Derive service_code and city_id from the lead.

Scan lib recursively so nested modules cannot escape the guard.

readdir without recursive: true returns only the top level of lib. A module in a subdirectory that builds an IN list from a result set passes both this test and the chunk-size test at Lines 199-213. Both scans need the same change.

BOUNDED_IN_LISTS then needs basename matching, because nested entries arrive as relative paths.

Import the accounts builder by name.

Line 130 falls back to the first exported function it finds. If buildAccountsBusinessView is renamed or removed, the test calls an unrelated export, and the assertions then describe a function the suite does not intend to cover. A named import fails loudly instead.

Add the D1 bound-parameter guard to this shim.

The seed suite drives generateSalesProductivityFacts and employeePerformanceCenter over 27 leads and 74 audience members, so a future read that builds an oversized IN list passes here and fails on D1.

- Line 7: Update the boarding, sitting, and training payout reads within
buildCompanyAnalytics to use chunkedIn, passing each booking-id chunk and its
generated placeholders into safeAll instead of constructing one large IN clause.
Preserve each query’s existing vertical-specific filters and result aggregation
while ensuring every per-booking read stays within D1 binding limits.

In `@lib/d1-chunked-in.ts`:
- Around line 17-20: Update the size validation in idChunks so it accepts only
positive integers, rejecting Infinity, NaN, and fractional values before
chunking; preserve the existing error behavior for invalid sizes and normal
slicing for valid ones.

In `@lib/manager-dashboard.ts`:
- Line 38: Update the employee query flow using chunkedIn so the combined
results are sorted globally by display_name after all chunks are concatenated,
preserving the prior ordering for scopes exceeding the chunk size.

In `@lib/people-reports.ts`:
- Line 30: Update the payrollApprovalEvents and incentiveApprovalEvents assembly
around chunkedIn so each combined result is globally sorted by descending
created_at and then truncated with slice(0, 200). Retain the existing per-chunk
SQL LIMIT 200 while applying this final limit after all chunks are combined.

In `@scripts/uat-demo-seed-gen.mjs`:
- Around line 65-70: Update the converted-lead booking generation in the seed
script so each bookingId is backed by a canonical booking row owned by the same
customerId. Either generate matching customer-owned booking records or select
existing bookings by customerId, while preserving null booking IDs for
non-converted leads and the require_canonical_lead_booking contract.

Apply the same fix in `@scripts/uat-demo-seed-gen.mjs` around lines 175 - 183: The
attribution facts repeat the same booking/customer consistency issue and should
use the canonical conversion pairing.

and tests/crm-stack-hardening.test.mjs:7-16 require no direct changes.
- Around line 101-109: The leaderboard test currently anchors report generation
to Date.now(), allowing the seeded assignments to fall outside the queried
window and metrics to become zero. Update the report setup around
generateSalesProductivityFacts and employeePerformanceCenter to use the fixed
seeded window via the report’s explicit anchor support, or assert the expected
leaderboard metrics directly from the generated run facts while retaining the
existing row and naming assertions.

Chunk the remaining per-vertical booking reads.

The boarding, sitting, and training payout queries still build one placeholder per booking. A service with more than 100 bookings will still fail D1 binding limits. safeAll then converts the failure to an empty result, which reports missing cost data instead of the real cost.

Use chunkedIn for all three queries.

Validate the chunk size as a positive integer.

Line 18 accepts Infinity, NaN, and fractional values. Infinity can put every ID into one query and exceed the D1 parameter cap. NaN can return no rows.

Proposed fix
-  if (size < 1) throw new Error("Chunk size must be at least 1");
+  if (!Number.isSafeInteger(size) || size < 1) {
+    throw new Error("Chunk size must be a positive integer");

Restore global employee ordering after chunking.

Each SQL query orders only its own chunk. chunkedIn concatenates chunks in input order, so a scope with more than 80 emails no longer returns the global display_name order from the former single query.

Sort the combined rows by display_name before returning them.

Keep converted booking and customer ownership consistent. The demo data currently links converted leads to bookings owned by different customers, and attribution facts use a separate booking/customer pairing. This can drop conversions or misattribute revenue in attribution and CAC views. Keep one canonical booking/customer pairing for each conversion and reuse it for both booking rows and attribution facts.

Green locally, red on GitHub, and the reason was one line: CI pins Node
22.13.0, where module.registerHooks does not exist yet - it arrived in 22.15.
Calling it unguarded threw `TypeError: nodeModule.registerHooks is not a
function` and took the whole test file down before a single test ran, so the
Web tests job failed on work that passes on a newer laptop.

Several suites already carried both branches inline - the modern API when it
exists, an out-of-thread loader hook when it does not. That pattern is now one
helper, tests/helpers/module-hooks.mjs, and the suites here use it.

The fallback was the half that had never been exercised, because on any
machine new enough to write it, it never runs. PAWSPACE_FORCE_LOADER_HOOK=1
takes that path on any Node, and a test fails if any suite calls registerHooks
without a fallback again.

A derived name hands the module an empty env rather than the one the suite
sets, which would make an env-dependent assertion pass for the wrong reason.

Splitting one `IN (...)` statement into several is not a free refactor. Three
things the single statement guaranteed change when it becomes N statements, and
none of them can fail a bind-cap test, because they all pass under 100 rows.

Subrequest cost. In lib/unit-economics.ts the chunked reads sit inside a helper
that first asks sqlite_master whether the table exists. Chunked, that guard is
charged once per chunk: eight guarded lookups over 5,000 bookings measured 1,012
D1 subrequests, and a Worker invocation is cut off near 1,000. The fix for
"too many SQL variables" would have re-broken the same screen one order of
magnitude further up, as a different error. The guard is now memoised for the
life of one request - per call, not per module, because a module-level cache
would remember "table absent" after another module created it and go on
reporting zeros for the rest of the isolate's life, which is the confident-zero
failure this file exists to remove. 1,012 subrequests -> 564.

LIMIT. In lib/people-reports.ts the payroll and incentive approval trails read
`ORDER BY created_at DESC LIMIT 200` inside the chunking, so the limit applied
per chunk: the trail could hold 200 rows per chunk, sorted only in blocks, and
the "newest 200" shown to a reviewer were not the newest 200. Both are now
sorted and cut over the whole answer.

ORDER BY. Checked every other chunked call site. lib/manager-dashboard.ts looks
like the same bug and is not: resolveDashboardScope already returns the scope
ORDER BY display_name, so chunks are name-contiguous and each chunk's ORDER BY
reproduces the global order. Same for the reads grouped by the very column being
chunked - every row of a group lands in one chunk. Nothing to fix there, so
nothing was changed there.

tests/chunked-in-semantics.test.mjs asserts all three. The first two run the
real module against a counting D1 shim above one chunk; each was confirmed to
fail when its fix is reverted (564 -> 1,012, and the wrong 200 events). ORDER BY
has no reachable failure today, so it is guarded at the class level instead: any
chunkedIn call site whose own statement orders or limits must either wrap the
concatenated rows in a reapplication or carry a recorded reason. That check
judges each call site on its own statement - a file-level "does it sort
somewhere" version passed while the payroll trail was still wrong.

Two suites call installWorkersHooks with a second argument naming their env
global, and the helper takes one parameter, so the name was dropped: the shim
read globalThis.__FANOUT_DB___ENV while the suite set __FANOUT_ENV__. Neither
suite reads an env value, so nothing failed - the first one that did would have
seen undefined with nothing to point at.

The parameter now exists and defaults to the derived name the older suites rely
on, so those keep working and the explicit call sites mean what they say.

Reviewed this for merge and pushed two commits to the branch (4863327, 06095c6) rather than blocking it — the core fix is right and the collected-₹0 bug is worth landing today. What I found:

The chunking made /api/unit-economics cost more subrequests, not fewer. Its reads sit inside a helper whose first act is a sqlite_master existence check. Wrapped in chunkedIn, that guard is charged once per chunk. Measured against a counting D1 shim:

bookings before this PR this PR after 4863327
1,000 172 212
3,000 492 612
5,000 ~812 1,012 564

A Worker invocation is cut off near 1,000 subrequests, so at ~5,000 bookings the fix for too many SQL variables would have re-broken the same screen one order of magnitude further up, as a different error. The guard is now memoised per request. Deliberately per call, not per module — a module-level cache would remember "table absent" after another module ran CREATE TABLE IF NOT EXISTS and keep reporting zeros for the rest of the isolate's life, which is the confident-zero failure this PR exists to remove.

ORDER BY created_at DESC LIMIT 200 inside the chunking applies per chunk. In lib/people-reports.ts the payroll and incentive approval trails could hold 200 rows per chunk, sorted only in blocks, so the "newest 200" a reviewer saw were not the newest 200. Both are now sorted and cut over the whole answer.

One thing that looks like the same bug and isn't: lib/manager-dashboard.ts. resolveDashboardScope already returns the scope ORDER BY e.display_name, so chunks are name-contiguous and each chunk's ORDER BY reproduces the global order. I wrote the fix, then wrote a test that proved it unnecessary, and reverted it. Same for the reads grouped by the column being chunked — every row of a group lands in one chunk. No change needed there.

tests/chunked-in-semantics.test.mjs pins all three. The first two run the real modules against a counting shim above one chunk, and each was confirmed to fail when its fix is reverted (564 → 1,012; the wrong 200 events). ORDER BY has no reachable failure today, so it's guarded at the class level: any chunkedIn call site whose own statement orders or limits must wrap the concatenated rows in a reapplication or carry a recorded reason. Worth noting the first version of that guard was worthless — it asked "does this file sort anywhere", and people-reports.ts sorts payroll runs elsewhere, so it passed while the approval trail was still wrong. It now judges each call site on its own statement.

06095c6 is separate and small: 83d939c passes a second argument naming the env global, but installWorkersHooks takes one parameter, so the shim was reading __FANOUT_DB___ENV while the suite set __FANOUT_ENV__. Neither suite reads an env value so nothing failed; the parameter now exists and defaults to the old derived name.

Also: the PR description says buildCustomer360 "on main still issues 8 queries per customer". That was true when this branch started but is stale now — #160 removed the N+1 and #166 sized the chunk. D1_IN_CHUNK = 80 matches what #166 measured, so tests/customer-360-fanout.test.mjs still passes; a chunk of 50 costs 82 calls for 500 customers against a 70 budget.

Gates on 06095c6: 1298/1298 tests on both module-hook paths (normal and PAWSPACE_FORCE_LOADER_HOOK=1, since CI pins Node 22.13.0), typecheck clean, lint at the repo baseline of 23 errors / 81 warnings. CI dispatched; merging on green.

Four conflicts, all on files #158 and this branch both created.

scripts/uat-demo-seed-gen.mjs — this branch's generator EXTRACTS each CREATE
TABLE from the file that owns it and validates every column in every insert
against that real DDL, refusing to emit a column that does not exist. #158's
inlined the DDL by hand. Kept this branch's framework and ported #158's twelve
tables of data into it, naming their four owning libs in SOURCES, so those rows
are now column-validated too - which they were not on either branch.

The two layers keep their own assumptions and are kept apart as sections 3 and
3b: the UATD-* rows are self-contained and prove out on an empty database, while
the sales and campaign rows reference staging-seed.sql's customers and bookings
so those screens are measured against real volume. #158's base date is kept for
its rows, so its leads still land inside the 7, 30 and 90-day windows the
leaderboard offers and the figures its tests assert are still the figures.

scripts/uat-demo-seed.sql — regenerated, never hand-resolved: hand-editing it is
the one path that bypasses the generator's column validation. 79 tables, 610
rows.

tests/uat-demo-seed.test.mjs — both branches created a file of this name and
they cannot become one file: each installs its own cloudflare:workers resolver
and only the first registered wins, so the second set of tests would read a null
database. They also load different fixtures on purpose - this branch's loads the
demo seed ALONE, which is the empty-staging case, while #158's loads the staging
seed alongside it. #158's tests are now
tests/uat-demo-seed-sales-marketing.test.mjs, unchanged except for the header
explaining the split and one assertion relaxed to accept this generator's
upper-case header line.

docs/STAGING_DEPLOY.md — this branch already documents loading the demo seed, so
#158's second load command would have been a duplicate instruction. Its content
is folded into the existing section instead, keeping the token-rotation gate that
blocks every --remote step, and using the generator's real invocation
(--experimental-strip-types, which #158's line omitted).

Gates: 1358/1358 tests on both module-hook paths, typecheck clean, lint at the
repo baseline of 23 errors / 81 warnings.

The only conflict was tests/helpers/module-hooks.mjs, which both this branch and
#158 created. Main's copy is a superset: same resolver and same Node 22.13
fallback, plus the env-global name as a real second parameter. Took main's.

Two corrections from independent QA review of the guard added in this PR. The
QA-002/QA-003 production fixes are unchanged.

Guard defect 1 - `line.includes("placeholders")` was an exemption

`placeholders` is the name chunkedIn gives the safe value it hands its callback.
It is also exactly what someone hand-rolling the unsafe build would call it, so

  const placeholders = ids.map(() => "?").join(",")

was accepted by the guard while being the precise shape the guard exists to
catch. Only an actual `chunkedIn` call satisfies it now. Removing the exemption
changes nothing in the real tree - no legitimate call site depended on it.

Guard defect 2 - BOUNDED_IN_LISTS exempted whole files

One known-bounded list bought a module permanent immunity, so a new
result-set-driven IN list added beside it was never seen. That is the same
file-level blindness that let lib/company-analytics.ts carry three unchunked
cost-ledger reads directly beneath a payments read #158 had already chunked -
the guard walked past the file it was written for. The allowlist now names the
specific bounded expression (petIds, rule.from, check.types, fyMonths and so
on), compared whitespace-insensitively, so anything else in the same file is
still judged.

The guard moves to tests/helpers/in-list-guard.mjs so the same function that
judges lib/ can be pointed at synthetic sources - a guard that has never been
shown to reject anything is a guard nobody has tested. legacyFindUnchunkedInLists
is kept there solely to demonstrate what the previous version accepted; it never
judges the real tree.

Both corrections are proved by mutation rather than described:

  - `const placeholders = ids.map(() => "?").join(",")`: the previous guard
    returns no offenders, the corrected guard returns victim.ts:1. A real
    chunkedIn call site still passes.
  - staff-alert-center.ts with a second, result-set-driven IN list appended: the
    corrected guard catches the new line while still allowing the bounded
    check.types call site; the previous guard returned nothing for the whole
    file.

Checked against origin/main, the corrected guard reports exactly the four call
sites of the original report: company-analytics.ts:23,24,25 and
people-reports.ts:18.

Two defects found by independent QA on main, plus the guard hole that let the
first one survive a sweep written to catch exactly it.

PAWSPACE-QA-002 - cost and margin vanish above D1's parameter cap

lib/company-analytics.ts:23-25 built three cost-ledger IN lists straight from
the booking ids (boarding, sitting and training payouts), directly beneath a
payments read that #158 had already chunked. Past D1's 100-bound-parameter cap
those reads fail, safeAll swallows them, and cost and margin silently disappear
for the vertical while GMV and collected stay correct - so the screen looks
healthy. Worse than absent: costCoverage then reports 0% for a period in which
every booking has a real payout row.

Measured on an identical fixture, only the row count changing:

   80 bookings -> gmv=80000   costAmount=48000  marginPct=40    coverage=1
  120 bookings -> gmv=120000  costAmount=null   marginPct=null  coverage=0

Fixed by routing all three through chunkedIn, as the payments read already was.

Why the sweep missed it - tests/d1-in-clause-fanout.test.mjs:176

The sweep exempted the whole FILE when it imported d1-chunked-in anywhere, so a
module that chunked one read became immune for every other read it built. The
exemption is now per line: a raw `.map(() => "?")` counts unless that same line
goes through chunkedIn. Sharpened, it names four call sites - the three above
and lib/people-reports.ts:18.

lib/people-reports.ts:18 - a 500, not a degradation

scoped() built the IN list from a manager's roster, and its `all` helper does
not swallow, so past 100 direct reports the whole People report threw
"D1_ERROR: too many SQL variables" instead of degrading. Confirmed by execution,
not inferred. Chunked through scopedAll(); because ORDER BY and LIMIT apply per
chunk, each caller reapplies both to the concatenated rows via newestFirstBy -
the rule this file already documents for its approval-event reads. leave_requests
now selects created_at so its ordering can be reapplied exactly.

PAWSPACE-QA-003 - CRM claims a customer has no bookings when it could not read

app/api/crm/route.ts published lifetime_value_basis "no_recognized_bookings" - a
positive claim that the bookings table was consulted and held nothing - whenever
the read FAILED, because the basis came from the result rather than from whether
the read returned. On a database without canonical_bookings every contact
rendered Rs.0 "no recognised bookings", indistinguishable from the truth; a
single failed chunk did it to 50 contacts while the rest of the page stayed
correct.

The failure is still swallowed - one absent module must not take the CRM down -
but now recorded: only contacts whose chunk returned earn a basis, the rest
report "unavailable" with a null figure. app/crm/page.tsx renders "Bookings
could not be read", stops collapsing null to 0, and no longer segments an
unread contact as high value.

Regression cover

tests/analytics-scale-truth.test.mjs (8) and tests/people-reports-scope.test.mjs
(4), real execution against node:sqlite with a shim enforcing the same
100-parameter cap production does: cost, coverage and margin hold at 120 and 240
bookings for all three verticals; CRM never claims a verified zero it did not
read, while a customer with genuinely no bookings still reads as such; a manager
with 120 direct reports gets a report and sees exactly their own roster.

With the product files reverted, 7 of 8 and 2 of 4 fail respectively - the
survivors are the "normal handling still works" controls.

Two source-string assertions that could not have caught either defect were
replaced with the executing equivalents (tests/people-reports.test.mjs pinned
the `AND 1=0` sentinel; tests/crm-stack-hardening.test.mjs pinned the assignment
that carried the bug).

unread contact as high value.

Regression cover

tests/analytics-scale-truth.test.mjs (8) and tests/people-reports-scope.test.mjs
(4), real execution against node:sqlite with a shim enforcing the same
100-parameter cap production does: cost, coverage and margin hold at 120 and 240
bookings for all three verticals; CRM never claims a verified zero it did not
read, while a customer with genuinely no bookings still reads as such; a manager
with 120 direct reports gets a report and sees exactly their own roster.

With the product files reverted, 7 of 8 and 2 of 4 fail respectively - the
survivors are the "normal handling still works" controls.

Two source-string assertions that could not have caught either defect were
replaced with the executing equivalents (tests/people-reports.test.mjs pinned
the `AND 1=0` sentinel; tests/crm-stack-hardening.test.mjs pinned the assignment
that carried the bug).

Two corrections from independent QA review of the guard added in this PR. The
QA-002/QA-003 production fixes are unchanged.

Guard defect 1 - `line.includes("placeholders")` was an exemption

`placeholders` is the name chunkedIn gives the safe value it hands its callback.
It is also exactly what someone hand-rolling the unsafe build would call it, so

  const placeholders = ids.map(() => "?").join(",")

was accepted by the guard while being the precise shape the guard exists to
catch. Only an actual `chunkedIn` call satisfies it now. Removing the exemption
changes nothing in the real tree - no legitimate call site depended on it.

Guard defect 2 - BOUNDED_IN_LISTS exempted whole files

One known-bounded list bought a module permanent immunity, so a new
result-set-driven IN list added beside it was never seen. That is the same
file-level blindness that let lib/company-analytics.ts carry three unchunked
cost-ledger reads directly beneath a payments read #158 had already chunked -
the guard walked past the file it was written for. The allowlist now names the
specific bounded expression (petIds, rule.from, check.types, fyMonths and so
on), compared whitespace-insensitively, so anything else in the same file is
still judged.

The guard moves to tests/helpers/in-list-guard.mjs so the same function that
judges lib/ can be pointed at synthetic sources - a guard that has never been
shown to reject anything is a guard nobody has tested. legacyFindUnchunkedInLists
is kept there solely to demonstrate what the previous version accepted; it never
judges the real tree.

Both corrections are proved by mutation rather than described:

  - `const placeholders = ids.map(() => "?").join(",")`: the previous guard
    returns no offenders, the corrected guard returns victim.ts:1. A real
    chunkedIn call site still passes.
  - staff-alert-center.ts with a second, result-set-driven IN list appended: the
    corrected guard catches the new line while still allowing the bounded
    check.types call site; the previous guard returned nothing for the whole
    file.

Checked against origin/main, the corrected guard reports exactly the four call
sites of the original report: company-analytics.ts:23,24,25 and
people-reports.ts:18.
