OSE-initiated onboarding: ADR-0013 decided, and an approval that admits

[satvikOS]

Resolves ADR-0013 and builds the OSE-initiated admission path it was blocking: an OSE administrator proposes a person who is not on the July workbook, the OSE Director decides, and only an APPROVED proposal writes to the access registry.

Rebased onto main after #113 merged (044e321), so the delta is only this work.

ADR-0013 — Accepted, option B

ApprovalRequest.organizationId is a non-null FK to Organization with onDelete: Cascade, and an onboarding proposal has no club. What settled it: a nullable column cannot express the rule we actually have. The rule is "null only for onboarding"; String? says "null for anything", and there is nowhere to put the difference — not the type, not a foreign key, not a constraint the database can check. Option A does not relax an invariant for one case, it deletes it for every club approval and every reimbursement on that table. #101 answered the same fork the same way. Option C (a synthetic institution-org) is refused explicitly so it is not rediscovered.

What an approval does, and the trap in each

1. The person enters the registry. A RestrictedIdentity row with all four provenance fields, computed by the writer and never supplied by a caller. Sharper than hygiene: sealRefusals refuses to seal a registry holding any ACTIVE row with missing provenance, and the seal is the only thing that makes the gate enforce — so one unaccountable row means the boundary can never be re-armed. addedBy is the decider, because it answers "under whose authority is this person on the boundary" and the proposer could not have admitted anyone.

The seal is deliberately untouched. The seal is evidence about a named authority, with a digest over exactly those addresses, and that statement stays true after an admission; rewriting the digest would make it attest to something nobody verified. Only a run that re-read the whole database may write one. The gate does not need it to — lookupRegistry reads the seal for existence only, never comparing digest or count at sign-in — so there is no window in which this weakens the boundary. The admission is an attributable delta, exactly the shape #113's planRegistrySeed already expects (it keeps such rows as extra, its comment naming this case: "an officer elected in November, admitted by an administrator").

2. Cognito — the honest half. No second provisioning path: provision-cognito-cohort.mjs reads the access registry, so an admitted person is already in its plan. But the app cannot create a Cognito user (the ECS task role is deliberately not granted AdminCreateUser), a created user sits in FORCE_CHANGE_PASSWORD which cognito.ts refuses as challenge-required, and the invitation cannot be emailed because SES is in the sandbox. So onboarding-readiness.ts reports Cognito as UNKNOWN rather than guessing, and the headline leads with what is not true. Nobody should tell a student "you're all set" off this screen, and 20 tests enforce that the copy cannot.

3. Billing — it emits nothing. Zero billable events, whether the person goes on to hold one seat or four. Under a person unit that is what keeps the count singular: the population is counted once by reading the registry, and a per-admission charge would be a second thing counting the same people. LedgerEntry was considered and is inexpressible, not merely wrong: it requires a non-null organizationId and budgetLineId, and an attempted write with neither is refused with Argument organization is missing (measured). It is a club's general ledger; reaching it would mean inventing a club for a person who has no club — option C.

The 82

ADR-0013 originally said the pilot's per-person charge was "64 units and not 145". countAdmittedPersons returns 82. 64 is the student-leader subset and excludes all 18 advisors, who hold access and sign in through the same boundary; the census sentence it came from is a statement about students. Escalated rather than silently edited, and the user decided: the billable population is everyone the gate admits, all 82. The correction is left visible in the ADR with the three populations tabulated (145 seats / 82 people / 64 students), because they are close enough to be swapped again — one of the three stale instances was inside the very paragraph arguing the registry is the right population. Three tests pin it, including that the count is not a cohort-filtered subset.

Caveat recorded in the ADR: the unique key is on emailNormalized, so it guarantees one row per address, not per human. For this tenant the readings coincide.

The bug 43 tests and 10 review findings all missed

A security review of the branch found no vulnerabilities — it independently verified that nothing reaches the registry without an APPROVED proposal, that R1/R2/R3 cannot be bypassed, that provenance is computed and never caller-supplied, that all queries carry institutionId, and that no subject PII reaches the advisor-readable audit log. It also confirmed the delegation claim I had only asserted: delegation.ts merges the role set and keeps the delegate's own userId, so effectiveApprovalContext genuinely cannot defeat R3.

But it found a real correctness bug by reading the schema against the state machine rather than by running anything. admittedIdentityId was @unique, which reads as "one proposal per registry row" and is the wrong invariant: a person is admitted, revoked on graduation, and admitted again on return — two proposals, one row. The second approval collided with the unique index and rolled the whole transaction back, uncaught. A returning officer could not be re-admitted at all. It fails closed, which is why it is a correctness bug and not a hole — but the path it closed is one this feature exists to serve. My revocation test passed only because its REVOKED fixture was created raw, with no prior proposal claiming it. Reproduced first, then fixed: plain index, one-to-many relation, and a regression test that walks the real lifecycle.

Two holes in the itest ownership guard, both measured rather than reasoned about. addedVia is nullable and SQL three-valued logic drops NULLs from NOT (x IN (…)), so a planted legacy ACTIVE row with null provenance counted 0, the guard stayed silent, and the row was gone after one run — precisely the row sealRefusals refuses to seal around. And VIA_ONBOARDING_CONSOLE stopped being a test-only marker the moment this feature shipped it, so a genuine console-admitted row satisfied the allowlist. The guard now also refuses any row outside the suite's own institution, which is the half that does not decay as the product grows.

Verification

tsc --noEmit clean, jest 1668 pass / 109 suites, test:isolation 127 pass / 6 suites (stable over three consecutive runs), npm run build compiled, decision-records 22/22, and prisma migrate diff --from-migrations --to-schema-datamodel --exit-code → No difference detected (which also confirms hand-written CHECKs do not register as drift).

Negative controls — each broken, seen RED, restored, GREEN: compare-and-swap → read-then-write; provenance written null; admission re-seals; subject into audit metadata; subject into audit reason; same-day reversal DELETEs instead of revoking; R1 check removed. Plus a direct database control on the CHECK constraints — each unlawful row refused by name.

Correction to the line above. It previously said "all five CHECK constraints ... a lawful control row accepted". It was three of five, and there was no lawful control row. decision_is_attributable and rejection_states_a_reason had no database control at all — and the first is the rule that decidedBy: onDelete: Restrict is justified by, so a referential action was defended by a constraint no test had ever seen fire. Both are covered now, in both directions, with the lawful row added.

Two of those controls were re-run after the review fixes and initially broke nothing, which is how the last two test gaps were found. A control calibrated against old code can be vacuous against new code.

findProposal(institutionId, id) exists for the console's withdrawal action, scoped by both. Withdrawal belongs to the author and no capability can express "is the author of this one" — every OSE staff member holds the proposing capability, so gating on it alone lets any staff member withdraw anyone's proposal by POST while the page correctly hides the button. TENANCY_ENFORCE is unset by default, so that where is the entire isolation.

Adversarial re-review (a second agent, attacking rather than reading)

Gate reproduced independently in a fresh worktree: tsc --noEmit 0 errors, jest 1668 passed / 1 skipped / 109 suites, test:isolation 146 passed / 6 suites, next build compiled, prisma migrate diff --exit-code No difference detected, all five CHECK constraints and the partial unique index read back from a live database.

The attacks held. Self-approval is refused with the actor holding OSE_DIRECTOR outright, refused for a Director deciding their own, and refused for reject as well as approve. R3 survives a real delegation — an ApprovalDelegation row was raised, effectiveApprovalContext called, the merge asserted to have actually happened (delegators contains the Director, the role set contains OSE_DIRECTOR, ctx.userId is still the actor), and the decision still refused; the same delegation approves somebody else's proposal, so the control is not vacuous. Escalation grants no membership, no role assignment and no seat, and the cohort enum cannot be made to hold an institution role even from raw SQL. Cross-tenant is refused four ways. The registry write carries all four provenance fields and the seal is untouched. The four-seat person is one billable unit and the ledger is untouched.

Four controls guarding those attacks were passing on fixtures the rule cannot reach. Fixed on this branch:

1. The billing control could not see the billing error. countAdmittedPersons was replaced with Math.max(admittedPeople, occupiedSeats) — honest per-seat billing with a per-person floor — and the suite stayed 70/70 GREEN, because no test ever put a person in a seat and Math.max(n, 0) === n. The test asserting it was even named "however many seats they hold" while holding none. The new control builds the pilot's worst case for real (four organizations, four roles, four SeatHolding rows, one human) and reads Expected 1 / Received 4 under that mutation — the per-seat invoice error, arriving silently. (The factor is 1.66x, not the 2.27x this branch and its brief were both written against: ADR-0017 remeasured the census and found 106 occupied seats over 64 students, 40 of 64 holding more than one, and nobody holding four — 145 had been every email cell in the club sheets, counting an advisor's attachment to a club as a board seat. The fixture still builds four, one past the measured maximum, because the property under test is that the count does not scale with seats AT ALL.)
2. The delegation property had never been executed. Both the module and its test credited R3's survival to withDelegatedContext, a symbol that does not exist in this repository; the real merge is effectiveApprovalContext, and nothing called it. Had that function ever overwritten ctx.userId with the delegator's, R3 would be defeated and every test would still have passed. Breaking it that way now turns four controls red.
3. The tenancy control was answered by the chokepoint, not by the store. Deleting institutionId from the WHERE in both decideProposal and withdrawProposal left the suite 38/38 green: tenancy/extension.ts injects the filter whenever a scope is open, in observe as well as enforce, and every control ran inside runInTenantScope. A script, cron job or tool call arrives with no scope, and then the store's own predicate is all there is. The new control opens no scope and goes red under exactly that mutation.
4. "All five CHECK constraints" was three — see the correction above.

What R2 does not close, now said in the two places that claimed otherwise. An advisor's own roles never reach OSE_DIRECTOR, but delegation.ts merges a delegator's whole set in, so an OSE_ADVISOR holding an ApprovalDelegation from the Director decides — measured: ["OSE_ADVISOR","OSE_DIRECTOR"], status APPROVED. That is the caller's question, not the library's; #120's console answers it by declining to merge for onboarding, and the registry row records the advisor as the admitting authority. Pinned by a test so narrowing it later is a decision rather than a silent change.

Also closed: the fixture cleanup now deletes audit rows before the institution (a refused decision writes one against the caller's institution, so a failing run left an orphan whose slug collided with the next run's — one red test becoming a suite red for unrelated reasons); an admission is proved not to block a re-seal by running planRegistrySeed/sealRefusals rather than reading them; and the stale ADR-0016 the branch corrected everywhere else survived in schema.prisma.

Checked and clean: no TODO/FIXME/"for now"/"in a real implementation"/stub/mock in the diff; no hard-coded Brittany, name or email; no parallel idempotency key (no LedgerEntry write at all); no second authorization path; no second Cognito provisioning path — and readRegistryRoster really does read RestrictedIdentity, so the "already in its plan" claim is true.

Review findings (all 10 addressed)

The one worth naming: the integration suite's ownership guard inspected only RestrictedIdentity while the cleanup also deleted RestrictedRegistrySeal unfiltered. A database with no registry rows but a real seal passed the guard, and the suite deleted the seal — which is the inverse failure. lookupRegistry reads the seal for existence, so with it gone decideEligibility admits every authenticated address while logging that it is not enforcing. Wiping the registry locks 82 people out and is noticed in minutes; wiping the seal lets strangers in and nobody notices. Confirmed not present on main.

Also: two referential actions that could only ever fail (decidedById and admittedIdentityId were SET NULL against CHECKs that forbid the result — both RESTRICT now); R1 was not enforced in the store (proposeOnboarding trusted the caller to hold the capability, so any script reached it ungated); the audit reason field was the side door on the confidentiality fix; provenance was restamped on rows another path admitted between propose-time and approve-time; the password step hard-coded a claim that would age into a falsehood; and ${input.action}d produced "rejectd".

Authorization and tenancy

Two new capability ids — onboarding.propose (OSE_STAFF, R1) and onboarding.decide (OSE_DIRECTOR, R2). Deliberately not reused from directory.manage/institution.grantRole: "edit a directory entry" and "admit a person to the boundary that decides who may sign in" are not the same permission. The capability is necessary and not sufficient — R3 (the proposer may never decide their own proposal, checked on user id so delegation cannot defeat it) comes from the rules module, and both must say yes.

OnboardingProposal is TENANT_SCOPED with pinned counts 23→24 and 42→43 and a dated rationale. organizationId is nullable with a composite FK (organizationId, institutionId) → Organization(id, institutionId) so a proposal cannot name another tenant's club.

Five CHECK constraints

The chain's rules restated as things a row cannot be, for the writer that never calls the rules module: R3 (decidedById <> submittedById), R4 (admittedIdentityId only when APPROVED), decided rows name both a decider and a time, a rejection states a reason, and subjectEmail = lower(btrim(subjectEmail)) — the seeder's casing bug made unwritable.

Still open, not resolvable here

Two open items a reviewer should not have to rediscover.

PR #120 builds a second store on this table. #120 (feat/ose-onboarding-console) carries lib/identity/onboarding-proposals.ts and onboarding-authority.ts — a parallel implementation of this feature — and carries no OnboardingProposal model or migration, so it depends on this PR landing first. Merging both as they stand gives two writers to RestrictedIdentity with two addedVia vocabularies. One of the two has to be rebased onto the other before either merges; that is a coordination decision, not something this branch can settle.

ADR-0017 now exists — this resolved itself. It arrived on main with #107: The billable unit is the person, Accepted 2026-08-21, and it is the same unit this path is written against. The citation in ADR-0013 and in schema.prisma therefore resolves without either being edited. Recorded here because the previous note said flatly that it did not exist and that decision-records.test.ts would not catch it — the second half is still true, and is why this had to be re-checked by hand rather than trusted to a green run.

Merged main in (aad855d), after #107 landed and made this branch CONFLICTING. Four conflicts, all in files that count things. The pinned model counts are the one worth reading: #113, #107 and this branch each added a model while written against 41 models / 22 TENANT_SCOPED, so the answer is 44 / 25 rather than either side's number. The conflict git raised there 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 silently. registry.test.ts compares the pins to the real schema, which is what turns that into a failure instead of a stale comment. Merged rather than rebased because a second agent is committing to this branch and a rebase would rewrite their commits.

And the merge itself introduced a fifth vacuous control. #107 brought a real seat meter (SeatMeterEvent) into existence between this branch being written and it landing. The billing control here asserted that an approval writes no LedgerEntry — complete when written, and silently narrowed the moment a second billable carrier existed. Adding a seatMeterEvent.create to admitToRegistry left the old control green; the new one goes red. A per-admission meter event on top of a per-person charge is a second thing counting the same people, and the four-seat case is exactly where the two answers differ by 4x.

Re-verified on the merge, with a rebuilt dependency tree (main brought @aws-sdk/client-sesv2 with #94; the stale node_modules failed three suites for reasons unrelated to the merge): tsc --noEmit clean, jest 1892 passed / 1 skipped, test:isolation 172 passed, next build compiled, prisma migrate diff --from-migrations --exit-code No difference detected against a database rebuilt from zero, and the pinning gates (registry, decision-records, constitution-completeness-compiler) green.

One commit is titled wip:. History was not rewritten because a second agent was committing to this branch concurrently and a force-push would have clobbered their work.

Merge Risk: 🟡 Moderate · up to aad85

The onboarding flow and billing behavior are covered by passing checks, but the current head can still report a proposal that did not create the registry row, producing incorrect admission provenance/source information; related decision and billing documentation inconsistencies also need owner follow-up, so merge should wait for that correctness issue to be fixed or explicitly accepted.

Reviewer flag: the per-person number in ADR-0013 does not match the code that computes it

Raising rather than silently editing, because the billable unit is under arbitration and the paragraph is not mine.

ADR-0013 line 148 says the unit is the person and therefore "the pilot's charge is 64 units and not 145". The function that would produce that charge is countAdmittedPersons:

return db.restrictedIdentity.count({ where: { institutionId, status: "ACTIVE" } })

For the pilot that returns 82, not 64. lib/tenant/restricted-cohort.ts is explicit about why: the reconciled cohort is "64 student leaders + 18 advisors", FALLBACK_RESTRICTED_COHORT_SIZE = 82, and both cohorts are ACTIVE rows that the gate admits.

There are three different populations in play and the document uses the name of one while the code counts another:

Unit	Pilot count	Where it comes from
occupied board seat	145	64 students × their club/position pairs
person with access	82	ACTIVE RestrictedIdentity rows — what countAdmittedPersons returns
student leader	64	the student subset only; excludes all 18 advisors

64 is neither the seat count nor the access-holder count. It is the student-leader subset, and it reads naturally as "the person count" only because the 64/145 pair is how the measurement was originally quoted.

Why this is worth fixing before merge rather than after. It is the number on an invoice. A rate card written against "64 people" and a meter that returns 82 disagree by 28%, in Tenure's favour, in a document that reads as settled — and the first person to notice will be the customer. It is also precisely the failure ADR-0015 warns about in its own domain: "an invoice has to be exact, reproducible, and the same number next month."

Nothing in the code changes either way, and this PR is correct under any unit — an admission emits zero billable events, which is the property the tests actually pin. Only the ADR sentence needs to say 82, or say "student leaders" if 64 was deliberate and advisors are genuinely not billable, which is itself a pricing decision nobody has recorded.

Two related items already in the PR body and still open: ADR-0016 is cited but does not exist in this branch, and #107's ADR-0015 says the unit is the occupied seat with a built meter behind it.

Review addressed — 9 of 10 fixed, 1 not mine to close

Thanks, this was a genuinely good pass. Two findings were real defects I would not have found, and one of those is the most serious thing in the PR.

The seal, which is the one that mattered. The ownership guard inspected only RestrictedIdentity while clearProposals also deletes RestrictedRegistrySeal unfiltered — so a database with no registry rows but a real seal passed the guard, and the suite deleted the seal. That is not a milder version of wiping the registry, it is the opposite failure: lookupRegistry reads the seal for existence, so without it decideEligibility falls back to its unenforced branch and admits every authenticated address, while logging that it is not enforcing. Wiping the registry locks people out and somebody notices in minutes; wiping the seal lets strangers in and nobody notices at all. The guard now covers all three tables and the proposal delete is tenant-scoped.

The audit reason was the side door. I had sanitised metadata and then passed the Director's free-text note straight into reason — which the audit page renders first (e.reason || summarizeMetadata(...)) to anyone holding audit.view, minRole OSE_ADVISOR. Both the decision and withdrawal paths now write fixed phrases; the note stays on the proposal behind the capability that already guards it.

Fixed, with reasoning in the commits:

Finding	Resolution
decidedById SET NULL vs attributability CHECK	RESTRICT — SET NULL could only ever abort, blaming a constraint the operator never touched
admittedIdentityId SET NULL detaches silently	RESTRICT — the admits-only-when-approved CHECK permits NULL, so nothing reported the loss
ownership guard misses two tables	all three covered; message names both causes, since a died-mid-run suite looks identical to a real registry and the remedies are opposite
proposeOnboarding has no authority gate	now calls canPropose; distinct from the capability check ("does this role hold this power" vs "does this actor propose at this institution") and both must pass
subject data in audit reason	fixed phrases on both paths
${input.action}d → "rejectd"	fixed
upsert restamps another path's provenance	an already-ACTIVE row is left alone and linked, with a RestrictedIdentity.AlreadyAdmitted event saying why nothing changed; a REVOKED row still restamps, because reactivating is this proposal's authority. Two integration tests pin both halves
password step asserted without an observable fact	takes firstPasswordFlowExists: OUTSTANDING while no flow exists (true of everyone, observable), UNKNOWN once one does. Never DONE, asserted over all 8 combinations
define "admitted person"	the ADR now says the unit is one admitted address, not one human, and states plainly that two addresses for one person would bill twice

That last one turned up a third instance of a number this PR had already corrected twice — "the registry holds 64 rows where the seat tables hold 145" was still there. It is 82.

Not fixed: ADR-0016 does not exist. Correct, and I have raised it — the billing unit is being arbitrated across this PR and #107, whose ADR-0015 currently says the occupied seat. Creating the ADR here would be me settling a question that is not mine. It is flagged in the PR body and to the owner.

One clarification on firstPasswordFlowExists and the Cognito step: both are deliberately un-inferable from application state. The app is not granted AdminCreateUser — provisioning runs under an operator's own IAM credentials with its own CloudTrail record — so DONE there would be an assertion about a system this process cannot read. The UNKNOWNs are the finished work, not a gap.

proposalId can name a proposal that did not admit the current row.

The schema states that "which proposal admitted this row, currently" is answered by the row's own sourceVersion (apps/web/prisma/schema.prisma Lines 1458-1462). This query answers it with the newest APPROVED proposal that links the row.

The two answers diverge in the already-active path. admitToRegistry preserves the existing provenance when the row is already ACTIVE, and decideProposal still writes admittedIdentityId onto the proposal. The row then keeps addedVia/addedBy from the earlier authority while proposalId reports the later proposal. The projection mixes two authorities in one record.

Deriving proposalId from sourceVersion keeps the record internally consistent.

🛠️ Proposed change

       effectiveFrom: true,
-      // Newest first, take one: a person may have been admitted more than once
-      // over the years, and the proposal a reader wants is the one currently in
-      // force. Ordering by `decidedAt` rather than by insertion, because that is
-      // the moment the authority was actually exercised.
-      admittedByProposals: {

Merge-train note: #115 and #116 were two implementations of one feature. #116 won.

This is recorded here so the next reader does not have to rediscover it.

#115 and #116 were developed in parallel from an older main (merge-base 9adc990a, neither is an ancestor of the other) and both implement OSE-initiated onboarding on top of the rules module that ADR-0013 shipped inert. They are not mergeable:

• both add model OnboardingProposal, with different columns and different enums (OSE-initiated onboarding: ADR-0013 decided, and an approval that admits #115: OnboardingStatus/OnboardingCohort; The onboarding chain gets a spine: its own model, and a delegation that cannot defeat it #116: OnboardingProposalStatus/OnboardingSubjectKind/OnboardingEventKind);
• both add a migration that runs CREATE TABLE "OnboardingProposal" — OSE-initiated onboarding: ADR-0013 decided, and an approval that admits #115's 20260821090000_onboarding_proposal and The onboarding chain gets a spine: its own model, and a delegation that cannot defeat it #116's 20260821090000_ose_initiated_onboarding_proposals. Same timestamp, different directory names, so Prisma would try to apply both and the second fails.

Measured on the merge of #115 onto #116's head: 8 conflicts, and the two models differ by 5 fields one way and 7 the other.

only in #115	only in #116
admittedIdentityId, admittedIdentity, justification, decisionNote, subjectEmailAsEntered	expiresAt, openSubjectKey, subjectKind, subjectKindOther, subjectEmailNormalized, decisionReason, events

#116 is canonical: it carries the richer spine (event log, expiry, subject kind, normalised subject key), #121 is already built on it, and it is now merged (59d1fb3b).

#115 is not redundant, and it must not be closed as if it were. #116's own code says so — onboarding-proposals.ts carries the comment "Nothing writes RestrictedIdentity on this path yet". So on the landed code, approving a proposal admits nobody. #115 is the half that actually admits (admitToRegistry, writing back admittedIdentityId).

I did not merge #115 and I did not gut it. Reducing it to what survives on #116's model leaves only onboarding-readiness.ts + its test — which nothing in the repo or in any open PR imports — so merging that would have added dead code while silently dropping the feature this PR's title names. The branch is left exactly as its author wrote it.

What has to be ported forward, as a change on top of #116's landed model:

1. The admission write. admitToRegistry + its call from the approve path. Without it, granting an OSE console role writes no registry row, so granting authority does not admit anyone.
2. The re-admission invariant, and specifically NOT as admittedIdentityId @unique. The real lifecycle is admit → revoke (graduates) → re-admit (returns as an advisor) = two proposals, one registry row. As a unique index the second approval collides and the whole transaction rolls back uncaught, so a returning officer cannot be re-admitted at all — the exact path the feature exists to serve. It fails closed, which is why it reads as correctness. OSE-initiated onboarding: ADR-0013 decided, and an approval that admits #115 already fixed this (898afbbb) and its migration carries the reasoning in a comment; port that test verbatim and negative-control it by name.
3. The columns the write needs: admittedIdentityId (not unique; plain index if lookup speed is wanted), justification, decisionNote, subjectEmailAsEntered.

That must go in a new migration that ALTERs the landed table. 20260821090000_ose_initiated_onboarding_proposals is already applied and Prisma checksums applied migrations, so it must not be edited.

One adjacent trap for whoever writes the port: the registry gate is asymmetric. lookupRegistry reads RestrictedRegistrySeal for existence, so no seal means eligibility falls back to unenforced and admits every authenticated address. Wiping the registry locks people out and is noticed in minutes; wiping the seal lets strangers in and nobody notices. And the natural key is emailNormalized — one row per address, not per human.

[satvikOS]

Closing. Superseded by #116, with its irreplaceable half already ported in #134.

#115 and #116 were two independent implementations of one feature. Both added model OnboardingProposal with different columns AND different enums, and both added a migration running CREATE TABLE "OnboardingProposal" under the same 20260821090000 timestamp with different directory names — Prisma would have applied both and the second would fail. One line had to win.

#116 won on the merits: richer spine (events, expiresAt, subjectKind, normalised subject key), and #121's admit console was already built on it. Both are merged.

Why this is closed rather than merged after dropping the duplicate model: with the model, enums and migration removed, what survived was onboarding-readiness.ts and its test — which nothing in the repo or any open PR imports. Merging that would have shipped dead code while silently dropping the feature this PR's own title names. That is worse than closing it.

Nothing was lost. The two pieces that mattered are on main via #134 (Closes #122):

• admitToRegistry — approving a proposal now writes the RestrictedIdentity row atomically with the transition, so the console admits the person instead of reporting a success that granted nothing.
• The re-admission invariant, with admittedIdentityId not unique. An approval admits the person: the registry write, and the re-admission invariant at both layers #134 found it existed at TWO layers, not one: reservesTheSubject also held the open-proposal slot on APPROVED — a documented stand-in for a registry check that could not fire — and that hold refused the returning officer one layer ABOVE the index. Fixing only the index would have left a returning advisor just as locked out.

The full port spec stays on this PR for the record.
