Two defects found by adversarially re-running this branch's own claims.
**1. A negative control that stayed green.** Deleting the `meterSeatOccupied`
call from `assignMember` — a club president adding an officer, the self-service
half of the product — left `npx jest` (109 suites, 1,623), `tsc` and the
"every path that changes who holds a seat meters it" ratchet ALL GREEN. The
ratchet only asserted that the FILE imports `@/lib/billing/seat-meter`, and
`meterSeatVacated` is still imported by `transitionAssignment` in the same
file, so the import survived the deletion. Deleting both term-transition emits
was invisible the same way. Playwright does not cover the route either:
`seat-metering.spec.ts` drives `/admin/clubs`, never `/orgs/[slug]/members`.
Three of the four club-side emit sites could therefore be deleted with every
automated check green, in the direction that silently costs money — which is
the exact failure the ratchet's own comment says it exists to prevent.
`a roster write and its meter row are in the same transaction` asserts the
property that was meant: every paren-balanced `$transaction(` body containing a
`roleAssignment`/`seatHolding` write must also contain a `meterSeat*` call.
Writes outside a transaction are pinned rather than ignored, so the rule cannot
be evaded by writing outside one; there is exactly one, the SHADOW hard-delete,
which meters nothing because a shadow was never metered as occupied. Strings
are blanked before parsing so a parenthesis in a refusal message is not read as
structure.
Controls, each confirmed RED then restored GREEN: delete the club assign emit;
delete both term-transition emits; delete the admin assign emit; delete the
admin revoke emit; add a file whose transaction writes a seat with no meter;
add a file that writes a seat outside a transaction. And confirmed to STAY
green when unbalanced parens are injected into a string literal, so the parser
is not brittle.
**2. Dangling and misdirected ADR citations.** The docs were renumbered
0016/0017 -> 0015/0016 and the code was not fully followed through. Three
citations pointed at `ADR-0017`, which does not exist in `docs/decisions/`, and
eleven attributed the billable unit and the money boundary to ADR-0016 when
both are decided by ADR-0015 ("The meter measures; the contract prices";
"Tenure's contract bills occupied seat-days"). ADR-0016 records only the
envelope conflict. The same files cited ADR-0015 correctly elsewhere, so the
file disagreed with itself.

satvikOS has reached the 50-credit limit for trial accounts. To continue receiving code reviews, upgrade your plan.
Both admin surfaces read the CURRENT academic year and passed it whole to `meteredQuantity`, which runs an occupancy with no closing row all the way to `period.end`. That is the correct reading of a period that is OVER and a forecast of one that is not — so a seat filled six hours ago reported 345.27 occupied seat-days beside a label that said "delivered seat-time". Measured against PostgreSQL on 2026-08-20: 345.27 reported, 0.25 delivered, and the tile rendered 345. Nothing caught it. Every unit test uses a closed September, where clipping to the period end is right; the Playwright spec only ever reads the "Seats occupied this year" tile, never seat-days. `elapsedPortion` clips the period at `now` before the unit sees it, and `meteredQuantityToDate` reads the facts to the same instant so a future-dated row cannot enter either. `meteredQuantity` stays, documented as the invoice run over a period that has ended, and a new ratchet keeps it out of `app/`. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The PR body, the backlog and ADR-0015 all state that a seat added by mistake and removed the same day "costs nothing". The kind, its writer and its refusals are real and tested against PostgreSQL — but `correctSeatMeterEvent` has no caller anywhere in the product. Every removal path meters VACATED, because a server action cannot tell a correction from a real departure and nothing asks. So today that seat is metered as a genuine short occupancy: measured at 0.25 occupied seat-days and one seat occupied for the period. Small in seat-days, whole in seats-occupied, and the opposite of the claim. Stated in the three places that claimed otherwise, and added to the capability registry's gaps beside the others, which is where "what this deliberately does not do" lives. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The spec only ever read "Seats occupied this year", which moves by exactly one whether or not the period is projected. The tile that carried the defect went unasserted end to end. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

In `@apps/web/src/app/`(app)/admin/metering/page.tsx:
- Around line 96-107: Update the asOfLabel and periodLabel formatting in the
metering page to use the institution time-zone value already obtained for period
computation, replacing the hard-coded UTC option while preserving the existing
date formats.
- Around line 51-57: The metering page currently resolves capabilities with the
hard-coded PILOT_SCOPE, allowing other tenants to receive the pilot grant;
update the capability-resolution flow around resolveCapability and
declaredModules to use the current institution’s CapabilityScope. Apply the same
scope correction in the app layout and AI chat route, and add a regression test
confirming a non-pilot institution declaring payments is not evaluated against
the pilot scope.
In `@apps/web/src/app/`(app)/admin/page.tsx:
- Around line 277-282: Update the unmetered-seat message in the reconciliation
display around meter.reconciliation.unmetered to describe the observed
roster/meter mismatch and non-billing without asserting pre-meter seeding as the
sole cause; mention both seats filled before the meter existed and seats missed
by the meter, while preserving the existing message for zero unmetered seats.
- Around line 231-291: Gate the seat metering BentoTile and its link on the
resolved payments.seat-metering registry capability in addition to the existing
billing.viewMeter check. Reuse the capability-resolution pattern and symbols
established near the checks around lines 82–95, ensuring tenants without the
payments module do not render a link to the metering page’s notFound path.
In `@apps/web/src/lib/billing/seat-meter.itest.ts`:
- Around line 471-475: Update the wholeYear assertions in the
meteredQuantity(YEAR) test to remove the calendar-dependent greater-than-100
threshold; retain only the invariant that wholeYear.occupiedSeatDays exceeds
toDate.occupiedSeatDays.
In `@apps/web/src/lib/billing/seat-meter.ts`:
- Around line 304-312: Update academicYearPeriod to validate that term consists
of exactly two four-digit year components separated by a single hyphen before
parsing them, rejecting malformed inputs such as leading hyphens and extra
components while preserving the consecutive-year requirement and existing
RangeError behavior.
In `@apps/web/src/lib/billing/seat-unit.test.ts`:
- Around line 399-411: Update the test around quantityForPeriod to use a clip
instant after the VACATED event, such as 2026-09-20, then pass the resulting
elapsed period instead of the unclipped { start: SEP, end: OCT } range. Keep the
expected occupiedSeatDays at 10 and retain the assertion that the clipped end
precedes OCT.
In `@apps/web/src/lib/billing/seat-unit.ts`:
- Around line 176-196: The occupancy sweep must pair OCCUPIED and VACATED facts
by occupancyRef regardless of effectiveAt ordering, so a backdated VACATED
closes the corresponding stay instead of leaving it open. Update the logic
around withoutCorrections, open, and danglingVacates to group or otherwise
reconcile each reference before creating the final span, while preserving
earliest-row handling and reporting references with only VACATED facts as
dangling.
In `@apps/web/src/lib/governance/blocked-architecture.test.ts`:
- Around line 156-159: In the mapping chain, remove the duplicated consecutive
filter declarations and retain a single type-guard filter that checks
Boolean(x.file), ensuring the arrow callback is properly closed so the test file
parses.
In `@docs/decisions/ADR-0016-seat-metering-without-an-outbox.md`:
- Around line 13-16: Update the quoted section around the Identity Bible and
Integration Bible references so it remains a contiguous blockquote: remove the
blank line or add a blockquote marker to it, resolving the MD028 violation.

Pass the current institution's CapabilityScope, not PILOT_SCOPE. PILOT_SCOPE hard-codes tenant "simon-ose", so a second tenant can be evaluated against the pilot grant when its manifest declares payments. The app layout and AI chat route repeat this fixed scope. Resolve the scope from the current institution and add a non-pilot regression test.

Format the labels in the institution time zone, not UTC.
Line 62 computes period in the institution's time zone on purpose. Lines 96-107 then format both labels with timeZone: "UTC", which discards that zone.
academicYearPeriod returns Aug 1 00:00 local converted to UTC. For a zone east of UTC the UTC instant falls in July, so periodLabel reads "Jul 2026 – Jul 2027" for an Aug-to-Aug academic year. asOfLabel has the same defect in the other direction: for a zone west of UTC, a Director reading the page in the evening sees the next day's date.
Reuse the zone that line 62 already awaits.

These assertions depend on the month the suite runs in.
YEAR runs from 1 August to 1 August. The occupancy starts six hours ago and has no closing row, so meteredQuantity(YEAR) measures the time from six hours ago to next 1 August. Late in the academic year that remainder is small: a run in, for example, May leaves under 100 days, and both assertions fail. The relationship being pinned is that the whole-period reading exceeds the to-date reading, and that does not need a calendar-dependent constant.

The term guard accepts shapes that are not an academic year.
term.split("-").map(Number) and the to === from + 1 check pass on inputs that the error message says are refused:
"-1-2026"splits to["", "1", "2026"]. The destructure takes""→0and"1"→1, and1 === 0 + 1holds, so the period is built for years 0 and 1."2026-2027-2028"splits to three parts and the third is ignored.
The function documents itself as the place where a caller that bypassed lib/tenant/term.ts is stopped, so match the shape explicitly.

…claimed first PR #101 independently adds `ADR-0015-the-platform-exception-object.md`. It was opened first, so it keeps 0015 and this change moves: ADR-0015-the-billable-seat-unit -> ADR-0016-the-billable-unit ADR-0016-seat-metering-without-an-outbox -> ADR-0017-seat-metering-without-an-outbox Whichever of the two branches merged second would otherwise have silently owned a duplicate number, and one of the two decisions would have become unreachable by the number every reference to it uses. Renumbering here leaves 0015 with no file until #101 lands, and `decision-records.test.ts` required the set of missing numbers to be exactly `[5]`. The literal was the right rule for one reservation and cannot express a second, so the index now DECLARES what it holds open — a table row with a bare number and a title opening `*Reserved` — and the guard reads that set instead of carrying it. The direction with teeth is unchanged: an undeclared gap still fails. Two checks are added rather than removed: a reservation must give a reason, and a reserved number may not have a file, so a row left behind after its ADR lands fails as loudly as a hole nobody declared. Every cross-reference moves with the files — both ADR bodies, the index table and its prose, the backlog, the BLOCKED_ARCHITECTURE register row, the capability registry, the schema comments and six source and test files. The rewrite ran as one validate-then-write pass with a per-file anchor count, after a first attempt wrote some files before discovering a wrong count in others and left the tree half-renumbered.

…BA reads it Two corrections, each put where the reader will be standing when the question occurs to them rather than only in the PR body. **ADR-0015 → ADR-0016, and the unit is the PERSON.** Five open PRs each claimed 0015 — every agent read main, saw 0014, and took the next number. The arbitrated assignment gives #101 0015, #107 0016 (the billable unit) and 0017 (seat metering). Two citations on this branch still pointed at 0015 and, worse, still described the unit as the OCCUPIED BOARD SEAT: the `organizationId` comment in schema.prisma and the billing negative control in onboarding-store.itest.ts. ADR-0013 itself was corrected in f2b15b3; these were not, and a code comment that contradicts the ADR it cites is worse than no comment, because it is the one a reader finds first. Both now say person, and both are aligned with the 82-not-64 correction in 9fe07ae — the double-count this control prevents is 82 people charged twice, not 64. **The onDelete reasoning goes into the migration.** `SetNull` was the first choice on `(organizationId, institutionId) → Organization(id, institutionId)` and is unsound: the key is composite, so a SET NULL would have to null `institutionId` as well, and that column is NOT NULL and is the tenancy column every scoped query filters on. Prisma warns about exactly this shape. RESTRICT is also the better answer on the merits and matches the precedent `AuditEvent` sets by carrying no cascade at all — deleting a club that a live admission record names should fail loudly rather than silently detach the record from the club that asked for the person. That argument existed in the schema comment and the PR body; neither is what somebody reads while looking at a failing DELETE in production, so it is in the migration now. No behaviour changes. `prisma migrate diff --from-migrations --to-schema-datamodel` → empty migration (SQL comments and `///` docs produce no DDL), `tsc --noEmit` clean, and the full `test:isolation` suite is 122/122 on a freshly-migrated database with `ledger.itest.ts` running first — the ordering that produced the CI failure fixed in 1d8945c.

…eadable The unit was the occupied board seat. It is now the PERSON: one distinct human is one billable unit for a period, however many board seats they hold in it. At the pilot's shape that is the difference between 145 club/position pairs and the 64 students holding them — 51 of whom hold more than one seat, so this is a 2.27x difference on the first invoice rather than an edge case. Changing the number required changing what the code can SEE, and that is the half that was not prose. `readSeatMeterFacts` selected eight columns and the occupant was not among them, so ADR-0015's own escape hatch — "a per-person rule can be written against rows that already carry who was in the seat" — described a column no code could read. `SeatMeterFact` now REQUIRES occupantKind and occupantId, so the reader's `select` fails tsc if it drops either; the guard is the type, not a comment. The unit is counted on `(occupantKind, occupantId)` — an identity, never an address. 86% of the roster's address cells are not lowercase, Identity §30 lists email as a person key among the things not to do, and invariant 13 forbids merging accounts because emails match. `upsertHolder` already normalises before it upserts and `User.email` is unique, so every seat one human is assigned resolves to one row and one id, and the database is what guarantees it. The kind is part of the key because the two id spaces are generated independently. What cannot be counted exactly is refused rather than absorbed: `meterSeat*` throws on a DIRECTORY_PERSON occupant, because nothing here can prove a DirectoryPerson and a User are one human — there is no Person (ADR-0009, IDENT-002) — and metering both would bill one person twice. Nothing writes one today; the refusal catches the change that would make the meter wrong, at the moment somebody makes it. Person-time is the UNION of a person's occupancies: four seats through one month is thirty person-days, not a hundred and twenty. The per-seat figures stay beside the per-person ones — the rows are deliberately finer than the unit, so a per-seat rate card remains possible and the size of the decision stays visible on the surface instead of being implied. Preserved deliberately: elapsedPortion and meteredQuantityToDate still clip both the period and the fact read, because person-days project exactly as seat-days did; meteredQuantity is still the closed-period invoice reading; the app/ ratchet and the reconciliation are untouched in behaviour. The reconciliation's own doc is corrected rather than left: under the person, an unmetered seat costs nothing when its holder is already counted through another, so that count is a direction and never an amount.

…rfaces with it The ADR now decides the person and keeps the structure that made the old one worth reading: the same question, the same two rejected options with their reasoning intact, and a new section saying exactly what changed about the argument rather than a conclusion bolted onto old prose. What changed is not that the constraint went away. There is still no `Person` and email is still forbidden as a person key, and the ADR says so. The old argument showed that folding a DirectoryPerson into a User is unavailable and then concluded that counting people is — which does not follow, because every occupancy this meter records already names one exact identity. The gap was never in the schema: `occupantKind` and `occupantId` had been on the row since it existed, and nothing selected them. Three things the ADR now carries that it did not: - **The four populations**, with the number each yields at Simon's shape and where each comes from: 145 occupied board seats, 82 people admitted, 64 student leaders, and the meter's own — distinct people holding a board seat. An advisor reaches a club through OrganizationAdvisor, which has no seat and no dates, so an admitted advisor can hold none. The failure this prevents is somebody reading "the unit is the person" and reaching for whichever count of people is nearest. Which population an INVOICE counts is named as a contract term and deliberately not settled here. - **What one person means across time**: one unit per person per billing period, and the period is the invoice's. Two seats at once cannot yield two units under any period a contract picks. - **A Migration section**, because a `Supersedes:` field without one is a supersession nobody can follow. Three changes, no data migration: the rows were always per seat and always carried the occupant, which is exactly why the unit could move without the history moving. Status is the single word `Accepted`, no qualifier — Constitution §5's "no final PARTIAL", enforced literally by decision-records.test.ts. The surfaces move with it, and every label now says what it MEASURES. No tile says "billed": this is a delivery meter, and with four populations in play a number under the wrong noun is the same defect as a wrong number. `seat-meter- boundary.test.ts` gains the ratchet for the defect itself — the occupant is declared required, is selected by the reader, and neither file folds on an address — because the type guard has an escape of its own that would look like a tidy-up in a diff. The e2e now executes the headline rather than a single assign: one person into FOUR board seats, asserting the person count does not move while the seat count moves by three. The seat assertion is what stops the person assertion passing because three clicks silently failed. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

…reSQL The unit tests prove the fold and the e2e proves the tile. Neither proves the thing that was actually broken: that the DATABASE hands the unit an occupant to fold on. That lives in a Prisma `select`, which no in-memory test executes — a select missing `occupantId` reads undefined for every row, folds the whole institution into one billable unit, and passes every unit test in the repository. Eight new cases against real rows: four seats is one unit and thirty person-days rather than a hundred and twenty; two people with two seats each is two units; one person across two clubs is one unit for the institution; two distinct people are never folded into each other; the same person at two institutions is one unit on each; the occupant survives the read; a DIRECTORY_PERSON occupant is refused; and an advisor holding a board seat bills exactly like a student. Existing cases are strengthened where the row count was standing in for the billing claim. "Replaying the same seat change bills once" asserted one ROW — which says the table is tidy, not that the invoice is right — and now asserts the quantity. The correction case gains the one the person unit adds: withdrawing a seat that was never true must not withdraw a human who really holds another, or the error swings from over-billing to under-billing in one edit. And the 1,382x clip is asserted on the person figures as well as the seat figures, because those are the ones an invoice is built from now. Every count here is either taken inside a tenant scope — where the extension has already added the predicate — or a delta the test measured itself. Verified the hard way rather than by reading: seven foreign meter rows were seeded into the same table and the suite was re-run. 26 passed with the noise present, and the full isolation suite is 5 suites / 101 tests green. An absolute count over a shared database measures whatever other suites left behind, and CI runs every itest against one database a two-tenant fixture has already populated.

… sequence Six open changes each wrote themselves an ADR-0015 — every one numbered against `main`, none able to see the others. The numbers were arbitrated across all six and this branch's two move again, from 0016/0017 to 0017/0018, because a change ahead of it in the sequence claims 0016. That churn is the argument for the mechanism this branch added rather than an argument against it. With a literal `[5]` in the guard, contiguity would force merge order and number order to be the same thing: one late review renumbers every branch behind it, and each renumber is a sweep across two ADR bodies, an index, a backlog, a register row and a dozen source files. With declared reservations each change states the numbers it does not hold and clears its own row when that ADR arrives, so the six can merge in any order. The index now reserves 0015 and 0016 and says who holds them. Also records the limit the counted identity actually has, in both directions. `RestrictedIdentity` is unique on `(institutionId, emailNormalized)`, which guarantees one row per ADDRESS and not one per human; the delivery meter shares that limit rather than escaping it, because it counts `User.id` and `User.email` is unique too. The readings coincide at this tenant for a stated reason — §3.2 permits one domain — and three foreseeable changes would break the equality: a second domain, an alias, a name change issuing a new address. Written down because the remedy is the Person that ADR-0009 holds open, and folding on a human identity this repository cannot prove would be wrong in a different direction rather than right.

student-email cells plus 40 advisor-email cells is 146. It counted an advisor's
attachment to a club as though it were a board seat somebody holds — the same
substitution the ADR warns about under "The four populations", committed by the
document that warns about it.
Verified here rather than relayed. `roster-source.mjs` states the committed
fixture is structurally identical to the real roster — "same 26 clubs, 209
seats, codes, vacancies and predecessor links" — and a walk of it returns 209
seats and 106 occupied, agreeing exactly with a figure already in the repository
that was not derived from the walk. The fixture's HOLDERS are reassigned, so its
person-level distribution is its own and the real 40-of-64 could not be checked
here.
So the test stops restating the number and measures it. `seat-unit.test.ts` now
builds meter facts from the roster fixture and asserts the unit reproduces its
shape: seats pinned at 209/106, and person-level facts asserted as PROPERTIES —
fewer people than occupied seats, multi-seat holders a large minority, someone
holding at least three. A hand-built "64 people, 145 seats" fixture would have
gone on passing forever, because it was only ever asserting its own arithmetic.
The correction is recorded VISIBLY in ADR-0017, with the table of both readings,
where 145 came from and the method to re-run it — this is the third numeric
error in this cluster of documents, and a silent fix teaches the next reader
nothing about how easily a count of one thing becomes a count of another.
What does not change is the decision. 62% of the roll still holds more than one
seat, so multi-seat holders are still the ordinary case and per-seat still
over-counts. The grain never depended on the magnitude. The four-seat fixtures
stay and now say they are constructed: four is one past the observed maximum,
the property does not depend on N, and a fold right for three and wrong for four
would be a strange defect.

…oes not move The spec now executes ADR-0017's headline in the product: one person into all four board seats of a club, asserting the person tile does not move while the seat tile moves by three. The seat assertion is what stops the person assertion passing because three clicks silently failed. Getting there found two defects in the spec itself, both of which produced failures that pointed somewhere else entirely. **Playwright locators are lazy, and the picker's DOM moves.** A seat whose person has been chosen swaps its search box for a chip, so `getByPlaceholder(SEARCH).nth(2)` names a DIFFERENT seat before and after the choice. The helper selected the person in one seat and then clicked Assign in the next one, which submits with nobody chosen; the server refuses with "A person is required", that surfaces as a 500 on the club page, and the test fails two steps later on a missing Remove button. Diagnosed by dumping every hidden `personEmail` on the page — the value was in the first picker while the read went to the second. Seat forms are now addressed by the hidden `roleId` they carry, which no interaction changes. **A seat card renders two forms carrying a roleId**, the delete-seat confirmation being the other, so the obvious selector returned ten ids for five seats and paired every seat name with the wrong id. The count guard written alongside it caught that on the first run, which is the only reason it was not an off-by-one that still passed. Seat ORDER is now asserted as a set, not a sequence: the page orders by `seatOrder` then `scope`, not by creation, and the first version of this hard-coded creation order. The picker indexes are read off the rendered order instead of assumed. Verified against a real server on a port checked free first, with the listening PID confirmed to be a child of the process this session started: 5 passed, including the four-seat case. Three servers were killed out from under this run by something machine-wide — each looked exactly like a test failure until the PID was checked, which is why the check is now part of running it.

changed the title
The workbook is TRACKED — '2026.2027 Club Org Student Leadership 7.17.xlsx' at the repository root. An earlier note in this branch said the real roster was not available here, which confused it with 'apps/web/scripts/roster-data.mjs': a DERIVED file that .gitignore excludes for a different reason. Two people reached the same wrong conclusion from the same line, so it is a trap in the repository rather than a lapse. So the census is now measured here rather than carried. Walking column D of the four club sheets: 53 + 25 + 17 + 11 = 106 occupied pairs over 64 distinct people, distributed 24 holding one seat, 38 holding two and 2 holding three — 40 of 64 above one, nobody above three, factor 1.656. That agrees cell for cell with the figure this branch was corrected to. The test still asserts PROPERTIES rather than these constants. The numbers are in the ADR with the method attached so anyone can re-run them; a fixture that hard-codes them is the thing that let 145 survive three documents.

…nt models PR #107 went CONFLICTING without anybody touching it: #94 (the SES send layer) and #113 (seed the restricted registry) merged into main after this branch's last green CI run and changed four of the same files. GitHub cannot build a merge ref for a conflicting PR, so no CI run was being created at all — the branch was not red, it was unreadable. Four conflicts, and three of them were the same shape: two changes adding different things in the same place. schema.prisma both add a relation to Institution and a model at the end of the file. Both kept. The conflict boundary cut through SeatMeterEvent's closing brace, which prisma validate caught rather than a reviewer. tenancy/registry.ts both add one entry to TENANT_SCOPED. Both kept. ledger provenance both rewrite the same counts sentence. The fourth was the interesting one and the reason this reconciliation is worth reading. `RestrictedRegistrySeal` and `SeatMeterEvent` each landed as "41 -> 42 models, 22 -> 23 tenant-scoped", because each was written against a main where the other did not exist. Naively taking either side would have left the pin one short and asserted a schema that no longer exists. It is 43 and 24, and the ledger now says so in one sentence covering both steps instead of two sentences each claiming to be the increment. That guard is exactly what it is for: two branches cannot both be the +1, and the second one through has to notice. It failed loudly on the merged tree — first on TENANT_SCOPED, then on the model count — rather than passing with a stale number and letting a tenancy claim drift. Verified on the merged tree, not on either side of it: tsc 0, jest 122 suites / 1873 passed / 1 skipped, build 0, isolation 6 suites / 115 passed, and `prisma migrate diff` returns an empty migration, so the migrations still reproduce the schema exactly. `npm ci` was re-run first — main added @aws-sdk/client-sesv2, and without it tsc fails on three files for a reason that has nothing to do with this branch.

…reconciled `main` moved under this branch when #107 merged. Four conflicts, all in files that count things, and the resolution is the sum rather than either side. **The pinned model counts.** #113 (`RestrictedRegistrySeal`), #107 (`SeatMeterEvent`) and this branch (`OnboardingProposal`) were each written against 41 models / 22 TENANT_SCOPED, because none could see the others. The answer is **44 / 25**, and `registry.test.ts` is what forces that: it compares the pins to the real schema, so restating one side's numbers is a failure rather than a comment nobody re-reads. Worth naming, because it is the trap this guard exists for: the conflict git raised here was in the PROSE ONLY. The four `toHaveLength` assertions auto-merged cleanly from one side and would have carried 24/43 into a resolved-looking file without a word of warning. A conflict marker is not the boundary of the conflict. **ADR-0017 now exists.** It arrived on `main` with #107 — *The billable unit is the person*, Accepted, and the same unit this path is written against. The dangling citation flagged in ADR-0013 and in `schema.prisma` therefore resolves, without either being edited. `docs/decisions/README.md` keeps main's 0015/0016 reservation note and now reads 8 of 15 Proposed, ADR-0013 having moved to Accepted in the change that implemented it. **The execution ledger** quoted 43/24 in SIMON-030-010's evidence and in its counts-provenance header; both now say 44/25 and name all three models. Verified on the merge with a rebuilt dependency tree — `main` brought `@aws-sdk/client-sesv2` with #94, and the stale `node_modules` failed three suites in a way that had nothing to do with the merge. After `npm ci`: `tsc --noEmit` clean, `jest` **1892 passed / 1 skipped**, `test:isolation` **172 passed**, `next build` compiled, and `prisma migrate diff --from-migrations --exit-code` **No difference detected** against a database rebuilt from zero. Merged rather than rebased: a second agent has been committing to this branch, and a rebase would rewrite their commits and need a force-push.

…othing said so `main` brought #107's seat meter (`SeatMeterEvent`) in between this branch being written and it landing. The existing billing control asserted that an approval writes no `LedgerEntry` — which was the complete answer when it was written and silently stopped being one the moment a second carrier existed. Adding a `seatMeterEvent.create` to `admitToRegistry` turned the new control red and would have left the old one green. That is the same failure this branch has now hit three times, from three directions: a control is correct about the world it was written against, the world moves, and nothing announces that the control's scope has narrowed. Here the cost would have been a per-admission charge on top of a per-person one — ADR-0017 makes the unit the PERSON and the population is counted once by reading the registry, so a meter event per admission is a second thing counting the same people. The four-seat control above is exactly where those two answers differ by 4x. `tsc --noEmit` clean, `jest` 1892 passed / 123 suites, `test:isolation` 173 passed, `next build` compiled.

… path `#107` landed the seat meter while this branch was open, and the two changes touch the same three seat-lifecycle functions. GitHub could not build a merge ref for a conflicting branch, so CI had stopped running on this PR entirely — the checks were not failing, they were absent. Resolved, rather than taken from one side: `orgs/[slug]/members/actions.ts` — main's shape wins for the WRITE (both `assignMember` and `transitionAssignment` now commit the roster row and its meter row in one transaction) and this branch's wins for what happens after it (the incoming holder is pointed at the seat's own briefing rather than at a list of names, and the incumbent is asked for unwritten lessons when a shadow successor is named). Neither displaces the other: the metering is inside the transaction, the notifications are after it and swallow their own failures. `notifyUsers` is no longer imported there — every send on that path goes through `lib/succession/handover.ts`, which is what `mail-has-one-door` allowlists. `tenancy/registry.test.ts` and the execution ledger — three models landed in one day, each written against 41 models / 22 tenant-scoped. 44/25 now, with all three named. Reconciled rather than restated, which is the whole point of the pin: the ledger's own body said 24 and the completeness compiler caught it. `capability-registry/routes.ts` — both routes, no arbitration needed. Gate after the merge: tsc clean, lint clean, jest 127/127 suites and 1951 passing, test:isolation 7/7 and 124 passing against a real database, next build clean with both new routes present, migrate deploy from empty clean, migrate diff reports no drift.

…ils (#124) Every deploy since #107 failed, and not because of #107. Terraform's refresh died on: Error: listing tags for ElastiCache Cluster (tenure-pilot-redis): StatusCode: 404, CacheClusterNotFound The service kept serving throughout — the migration step runs before the ECS service is touched, so a failure there leaves production on the previous version. That ordering did its job. ── Why the existing guard did not catch it ───────────────────────────────── A guard for exactly this was added on 2026-08-17, when the same 404 took the pilot down. It ran, and it reported: ✅ ElastiCache cluster tenure-pilot-redis still exists in AWS It asked `describe-cache-clusters`, which SUCCEEDED. Terraform asks `ListTagsForResource`, which 404s. A cluster mid-delete can be described but not tagged, so the guard answered a different question confidently and left the resource in state while every apply kept dying. The guard now probes with the operation that actually fails. A guard that asks a different question than the thing it guards will be wrong exactly when it matters. ── Why removal rather than a stronger guard ──────────────────────────────── Nothing uses Redis. No client is installed; the three `redis` hits in application code are `rediscovering`, `redistributed` and `rediscovered`. The only consumer was an ECS environment variable, REDIS_URL, pointing at a host nothing ever opened — so the cluster's absence was invisible until terraform tried to refresh it. This is also what the user asked for earlier: delete dependencies that were planned and are not needed. Removing the resources from the configuration is NOT sufficient on its own. Terraform refreshes everything in STATE whether or not it is still declared, so the same 404 would recur. The guard step now drops all four addresses from state, and the configuration no longer recreates them. Gone: elasticache.tf, the redis security group, the redis_node_type variable, the redis_endpoint output, and the REDIS_URL environment variable. Co-authored-by: Claude <noreply@anthropic.com>

main moved under this branch while it was being verified — #107 (the seat meter and ADR-0017/0018) and #124 — and left the PR CONFLICTING, which is why no CI run had started: GitHub cannot compute a merge ref for a dirty PR, so the checks were not "pending", they did not exist. Four conflicts, all of them counters that exist precisely to make this loud: - `tenancy/registry.ts` + its test — three branches each added models against 41/22. Reconciled to 26 TENANT_SCOPED of 45, verified by the test's own parse of schema.prisma rather than by arithmetic. - `decisions/README.md` — main's reservation mechanism for the arbitrated ADR numbers is kept whole; the Proposed count is 8 of 15, not 9, because ADR-0013 is Accepted on this branch. The paragraph explaining that ADR-0013 left the Proposed set is kept beside main's ADR-0017 counter-example. - the execution ledger's counts-provenance — now records all three steps from 41/22 rather than either branch's two.

main took #107 (the seat meter, ADR-0017/0018), #124 (ElastiCache removed), #125 (the tenancy prose corrected against its own pins) and #126. Six conflicts, and every one of them is a counter or a registry that exists to make exactly this loud rather than silent: - schema.prisma both sides append disjoint models; kept both. - capabilities.ts exception.resolve/waive and billing.viewMeter; kept both. - registry.test.ts the four pinned counts. MEASURED against schema.prisma, not incremented: this branch was written against 41 models / 22 tenant-scoped and main had moved to 43/24, so either side's number carried forward alone would have been wrong by two. Now 44 models, 25 TENANT_SCOPED / 5 PLATFORM_GLOBAL / 14 UNENFORCEABLE, which sums to 44. - registry.ts the doc comment sentence #125 added a test for. 25 of 44, with a dated rationale. - docs/decisions ADR-0015 LANDS here, so its reservation row is DELETED. 0016 stays reserved. 9 of 16 are Proposed. - the ledger counts-provenance and the SIMON-030-010 row, reconciled to the same measured numbers. And one thing git reported no conflict for, because the directory names differ: the migration 20260820140000_exception_register collided with main's 20260820140000_idempotent_accounting_intake. Two migrations sharing a timestamp is a broken deploy rather than a red merge, so it is bumped to 20260821093000_exception_register — after everything on main.

main took #125 (the tenancy doc comment corrected against its own pins) and #126 (the DKIM token check). This branch had already merged main at 2d4469a for #107 and #124. One conflict, and one thing that was NOT a conflict and mattered more: - registry.ts the doc-comment sentence #125 added a test for. Kept this branch's 26 of 45; main's 24 of 43 does not know about OnboardingProposal or OnboardingProposalEvent. - registry.test.ts AUTO-MERGED. The four pinned counts are the assertion that actually guards the tenancy boundary and git resolved them silently from one side. They were re-derived from schema.prisma with the test's own parser rather than trusted: 45 models, 26 carrying institutionId, and 26 + 5 + 14 = 45. They were already correct, but only measuring could say so. Migration timestamps checked against main: this branch's two (20260821090000_ose_initiated_onboarding_proposals and 20260821140000_decline_states_a_reason) collide with nothing. The one duplicate in the directory, 20260820120000, is main's own pair and predates this branch.

What this is
Adding a seat on the tenant side now produces a durable, idempotent billable
event, and the unit those events are counted in is the PERSON.
SeatMeterEventis written in the same transaction as every roster writethat changes who holds a seat — the admin console's assign, revoke and transfer
paths, and the club's own assign and term-transition paths — so there is no
window between the seat and the emit for a crash to fall into.
(institutionId, sourceEventKey)is UNIQUE and the key is minted only bylib/billing/metering-events.tsbehind a branded type, so a re-delivered seatchange is refused by PostgreSQL rather than by a read-then-write guard that two
concurrent writers both pass.
The open decision, answered — ADR-0017
The programme item recorded seat-versus-occupied-seat as undecided. The answer
is the third option it did not name.
The billable unit is the PERSON. One distinct human is one billable unit for
a billing period, however many board seats they hold in it.
At the pilot's shape that is 64 people against 106 occupied board seats (of
209 seats in all) — 40 of the 64 hold more than one seat, so it is a 1.66x
difference on the first invoice rather than an edge case. Measured from the
tracked workbook, with the method and the per-sheet counts in the ADR.
and — worse — would pay a tenant to delete
Rolerows, which the schema callsthe anchor that "outlives every holder" and that all institutional memory
hangs from. A pricing model whose rational response destroys the product is
not a pricing model.
club and keeps the books for another is one student.
invoice's. Two seats at once cannot yield two units under any period a
contract picks.
the person is aggregated from those rows at read time. You can always
aggregate a finer measurement and never split a coarser one, so a per-seat
rate card remains expressible and both readings are reported side by side.
What changed since the first version of this PR
This PR previously decided the occupied seat, and defended it with an escape
hatch: "the meter records the occupant even though the unit does not price
them — the day a
Personexists, a per-person rule can be written against rowsthat already carry who was in the seat."
The columns were there.
readSeatMeterFactsselected eight of them and theoccupant was not among them, so no code in the repository could read it. The
hatch was prose.
That is the half of this change that is not a document.
SeatMeterFactnowrequires
occupantKindandoccupantId, so aselectthat drops eitherone fails
tscrather than silently billing seats — and the negative controlfor it is a compile error, not a test.
The unit is counted on
(occupantKind, occupantId)— an identity, never anaddress. 86% of the roster's address cells are not lowercase, Identity §30 lists
email as a person key among the things not to do, and invariant 13 forbids
merging accounts because emails match.
adminAssignSeatalready normalisesbefore it upserts and
User.emailis unique, so every seat one human isassigned resolves to one row and one id, guaranteed by the database rather than
by convention.
What cannot be counted exactly is refused rather than absorbed: the writer
throws on a
DIRECTORY_PERSONoccupant, because nothing here can prove aDirectoryPersonand aUserare one human (ADR-0009,IDENT-002) andmetering both would bill one person twice. Nothing writes one today; the refusal
catches the change that would make the meter wrong at the moment somebody makes
it.
Four populations, and which is which
The likeliest way this decision gets misapplied is somebody reaching for
whichever count of people is nearest. ADR-0017 names all four with sources:
106 occupied board seats, 82 people admitted to the institution (64
student leaders + 18 advisors), 64 student leaders, and the meter's own —
distinct people holding a board seat. An advisor reaches a club through
OrganizationAdvisor, which has no seat and no dates, so an admitted advisorcan hold none and appear in no reading of this meter.
Whether an invoice counts access or delivery is a contract term the ADR
names and deliberately does not settle. This meter measures delivery. No tile
says "billed".
Corrections, and a claim that is stated in the right tense
A seat added by mistake at 09:00 and removed at 15:00 is not a six-hour
occupancy.
CORRECTIONwithdraws the row from every reading, while a genuinesix-hour stay still contributes six hours. Withdrawing a wrong row does not
withdraw the human: if the occupant genuinely holds another seat they remain one
billable person on the strength of it.
correctSeatMeterEventis built and tested against PostgreSQL and has nocaller anywhere in the product. Every removal path meters
VACATED. The ADR,the backlog and the capability registry all say so in that tense.
A live period is read to date, never to its end
quantityForPeriodruns an occupancy with no closing row toperiod.end, whichis right for a period that is OVER and a forecast for one that is not. Both
admin surfaces read the current academic year, so a seat filled six hours ago
reported 345.27 occupied seat-days against 0.25 delivered — a 1,382x
over-report on the tile the contract bills on.
elapsedPortionclips the periodand the fact read at
now;meteredQuantityis kept for closed-period invoiceruns, and a ratchet keeps anything under
app/from calling it.ADR numbering
Six open changes each wrote themselves an ADR-0015, every one numbered against
main. The numbers were arbitrated; this branch takes ADR-0017 (thebillable unit) and ADR-0018 (seat metering without an outbox), and all 45
cross-references move with the files.
decision-records.test.tsrequired the set of missing ADR numbers to be exactly[5], which is the right rule for one reservation and cannot express a second.The index now declares what it holds open — a table row with a bare number
and a title opening
*Reserved— and the guard reads that set instead ofcarrying it. The direction with teeth is unchanged: an undeclared gap still
fails. Two checks are added rather than removed — a reservation must give a
reason, and a reserved number may not have a file. Consequence: merge order and
number order no longer have to be the same thing.

Gates on the merged tree: tsc 0, jest 122 suites / 1,873 passed / 1
