Sessions the server can actually end, and the five events that end one

[satvikOS]

The finding that shaped this

session.deleteMany had zero call sites, so the obvious fix was to add them. That would have changed nothing.

auth.ts sets session: { strategy: "jwt" }. Under that strategy @auth/core never creates, reads or deletes a Session row — handleLoginOrRegister skips the adapter entirely for credentials sign-ins, and a request is resolved purely by decrypting the cookie. The Session table was dead weight carried by PrismaAdapter. Deleting every row in it would have satisfied the grep in the backlog's own evidence line while leaving every session alive.

Two adjacent traps, both read out of the installed @auth/core rather than assumed:

• jwt.encode calls .setIssuedAt() and .setJti(randomUUID()) on every encode, and session() re-encodes on every read to refresh expiry. token.iat and token.jti therefore move forward on every page load — a revocation watermark compared against either would never fire.
• auth() inside a server component cannot set cookies, so nothing may be cached in the token.

What was built

The JWT stops being the session and becomes a bearer of one.

• At sign-in the jwt callback mints a random sid and writes a Session row.
• On every read it looks the row up and returns null when it is gone or expired.
• @auth/core treats a null from jwt as no session: response body null, cookie cleared, auth() resolves to null, and the (app) layout redirects to /signin.

Deleting the row is the revocation. Cost: one indexed lookup per session read — the price of §14.2's "server-controlled and revocable". The existing Session model is reused (already PLATFORM_GLOBAL, so no scope juggling and no registry count change); the migration adds only two indexes, because every trigger deletes by person and none knows a session id.

The five triggers

#	Trigger	Where
1	membership end	adminRevokeInstitutionRole, acceptRoleTransfer
2	assignment status change	adminRemoveAssignment (both branches), adminTransferSeat, transitionAssignment
3	affiliation end	detected — api/jobs/access-reconciliation
4	identity-link activation	auth.ts, Cognito provider, before the new session is minted (§15.1 step 7)
5	provider deactivation	detected — same job, via AdminGetUser

3 and 5 have no call site in this repository and one was not invented. Nothing in the product writes RestrictedIdentity (grep: two reads, zero writes), and no SCIM feed or webhook tells this deployment that Cognito disabled an account. A change nobody reports has to be detected, which is what the reconciliation hook in the item's title is. It runs every 15 minutes (scheduler.tf), and that interval is the guarantee for those two — the other three revoke inside the request that causes them.

The pass refuses to revoke on three conditions, all of which a live environment produces routinely and each of which would otherwise sign out the whole tenant: an empty roster (the boundary has decided nothing — the same position decideEligibility takes at sign-in), a failed pool probe (throttling is not a statement about a person), and an address with no pool account (the census found one identity for an 82-person cohort).

Proof, not assertion

e2e/session-revocation.spec.ts creates an officer through the product's own roster form, signs in as them, has a manager end their term, and shows the same browser with the same cookie landing on /signin.

It asserts /signin and explicitly not /access-pending, and that is the whole discriminator: ending the officer's only seat also makes them unentitled, and the entitlement gate has redirected unentitled people to /access-pending since it landed. A run in which revocation does nothing still looks like the officer being turned away.

The negative control ran that exact experiment. With the jwt check disabled and the app rebuilt, the spec failed with:

Expected pattern: /\/signin/
Received string:  "http://localhost:3111/access-pending"

— which is precisely today's behaviour, and precisely the defect.

Measured latency: 373–501 ms across runs, printed by the spec. That is wall-clock from the operator's click to the officer's next request being refused, including a browser navigation and a full server render — an upper bound on revocation, not a measurement of the delete. Trigger 3 was also driven end to end by hand against a real server and database: /api/auth/session returned a user, the roster was populated without them, the pass revoked 7 sessions with trigger affiliation-ended, and the same cookie then got null and a 307 → /signin.

The outbox half is BLOCKED_ARCHITECTURE

The item asks for an outbox event. There is no carrier and a second one was not built.

Identity §21.2 requires an aggregate, a causal decision and an actor identity that Integration §9's canonical envelope has no field for; §9 requires connectionId/integrationId/runId/mapping, which an internal revocation cannot supply, and a payloadRef where §21.2 wants a safe payload. Disjoint, unresolved.

Recorded as ADR-0015 and register row IDENT-003-session-revocation-event-emission. RevocationReceipt.outboxEventEmitted is typed false — in the type, not a comment — so nothing downstream can assume an event went out, and the register's backwards liveViolation predicate watches that field: when an outbox lands and it stops being false, the row goes red and has to be closed.

Negative controls

Each break was applied, the suite run, and the change reverted.

Control	Result
A — Prisma store's deleteAllFor returns 0	first run: STILL GREEN. The unit suite runs on an in-memory store, so a revocation that revokes nothing failed nothing. Closed by adding session-revocation-prisma-store.test.ts; re-run: RED
B — session id authorizes whoever presents it	RED
C1 — roster guard removed and "not active" treated as ended	RED
C2 — same mis-simplification, guard intact	GREEN — proves the guard absorbs it rather than decorating it
D — absent pool account read as deprovisioned	RED
E — transitionAssignment stops revoking	RED (trigger test and ratchet)
F — jwt callback never checks the server-side session	RED in jest; RED in the browser, landing on /access-pending
G — outboxEventEmitted stops being false	RED — the register's backwards predicate fires
H — a brand-new unwired roleAssignment.updateMany	RED — the ratchet catches an unwired call site
I — §15.1 step 7 rotation dropped	RED
J — OSE role revocation leaves the session alive	RED
L — one unreadable subject aborts the pass	RED

One control was a silent no-op — a Python patch whose anchor did not match printed PATTERN MISSING and the suite then reported "STILL GREEN" over unmodified code. It was caught only because every patch asserts its anchor; the control was rewritten with an exact string and came back RED.

Verification

• npx tsc --noEmit ✅ · npx jest 1644 passed ✅ · npm run build ✅ · next lint 0 errors ✅
• prisma migrate diff --exit-code — no drift ✅
• Full Playwright suite: 166/166 against a production build, a real Postgres and a clean seed ✅
• The job endpoint exercised for real: 401 unauthenticated, 401 on a wrong token, and a report on the right one. With an unreachable Cognito pool it revoked nobody and the signed-in president still loaded /dashboard — the dangerous direction, proven safe.

Consequences worth reading before merge

1. Everyone signs in once more after deploy. A token minted before this shipped carries no sid, has no row behind it, and is therefore unrevocable — exactly what this item exists to abolish. It is refused rather than grandfathered; the alternative is a thirty-day window in which revocation silently does nothing.

2. One §13.2 case is deliberately not covered. adminGrantInstitutionRole's upsert can move a Director to Advisor. That is a role change within a continuing membership, not a membership end; §13.2 asks for rotation rather than revocation, and revoking there would also sign out everyone newly granted a role by the same call. Named in session-revocation-is-wired.test.ts and in the backlog rather than left to be discovered.

3. A database fault signs people out, and nothing revoked them. Added by adversarial verification, and measured rather than reasoned: hide the Session table under a live session and @auth/core cannot distinguish a throwing lookup from a refused one — /api/auth/session answers null and sends Set-Cookie: authjs.session-token=; Max-Age=0, so the browser deletes its cookie. The row survives untouched (161 rows before and after), so nothing was actually revoked, but every browser that polled during the blip must sign in again once the database recovers. The behaviour is correct and is deliberately left alone — a session that cannot be checked must not be honoured — but the symptom (a wave of sign-ins, no revocation in the audit log, every Session row still present) reads like a security incident to whoever is on call. Now named in docs/RUNBOOK.md.

Merge-time hazard: ADR-0015 is contested by three other open PRs — RESOLVED 2026-08-21

This section is kept for the record and is no longer actionable. The collision it predicted happened: main took ADR-0015 for the platform exception object, and this PR is renumbered to ADR-0016 — see the merge note at the bottom. Two details below are also out of date: decision-records.test.ts no longer asserts gaps === [5], it requires the set of gaps to equal the set of reservations the index declares, so a number may be held open deliberately; and #107 landed as ADR-0017/0018 rather than 0015/0016.

Not a code defect, but it will break whoever merges second, so it belongs in the body rather than in a hand-off note. Four open PRs currently introduce ADR-0015:

PR	File
#104 (this one)	ADR-0015-session-revocation-event-emission.md
#101	ADR-0015-the-platform-exception-object.md
#106	ADR-0015-tenant-configuration-packs.md
#107	ADR-0015-the-billable-seat-unit.md (and ADR-0016-seat-metering-without-an-outbox.md)

Whoever merges second renumbers — and the renumbering is not free-choice. decision-records.test.ts asserts expect(gaps).toEqual([5]), i.e. ADR numbers must be contiguous with 0005 the single reserved gap. So the next PR in must take the next contiguous number, not an arbitrary free one; jumping to 0017 to dodge the clash would fail CI on the gap it leaves. Renumbering this PR means updating the filename, governance/register.ts (adr.id and adr.file), the docs/decisions/README.md index, and the ADR-0015 references in session-revocation.ts, access-reconciliation.ts, PROGRAM-BACKLOG.md and RUNBOOK.md.

Adversarial verification (this PR's own verifier died before running)

Verified in a dedicated worktree at c5392be, against a production build, a real PostgreSQL 16 and a real seed. Fixes pushed as ca711dc on this branch. Not merged.

The central claim is TRUE, and it is the load-bearing one

Read out of the installed dependency rather than the report. The installed version is @auth/core 0.41.2, not the 0.37 the source comments cite — the claim holds on the version that actually ships:

• lib/actions/callback/index.js:227 — the provider.type === "credentials" branch calls authorize → handleAuthorized → callbacks.jwt and never reaches handleLogin/createSession.
• lib/actions/session.js:21 — if (sessionStrategy === "jwt") returns at line 63, before getSessionAndUser / deleteSession / updateSession at lines 67–68.
• lib/actions/signout.js:15 — the jwt branch only decodes and fires the event; adapter.deleteSession is in the else.

So session.deleteMany would indeed have satisfied the backlog's grep and revoked nothing. The design is right.

The contract block in session-revocation-is-wired.test.ts resolves @auth/core through Node and asserts against the installed source, so the stale 0.37 in the prose is a documentation nit only — an upgrade that breaks the contract still fails the build.

Gate, reproduced independently

npx tsc --noEmit ✅ · npx jest 110 suites, 1655 passed, 1 skipped ✅ · npm run build ✅
(The body's "1644" was written two commits early; it was 1649 before my six new tests.)

e2e/session-revocation.spec.ts re-run against a production build + real Postgres: 3/3 passed, [measured] revocation observable after 411ms — inside the author's stated 373–501 ms.

Revocation genuinely works — proven independently of the spec

Signed in with curl, then DELETE FROM "Session", same cookie throughout:

	before	after
/dashboard /approvals /orgs /settings /notifications /reports	200	307 → /signin
/api/notifications, /api/search	200	401
/api/auth/session	user JSON	null

Sign-out deletes exactly one row (4 → 3). Two devices, one revoke-by-person: 200/200 → 307/307.

Three defects found and fixed in ca711dc

1. A totally failed reconciliation pass was indistinguishable from an idle one. Measured, not reasoned: renaming RestrictedIdentity under a live pass made every subject's fact read throw, and the endpoint answered HTTP 200 with byte-identical JSON to a healthy run — {"subjectsChecked":1,"skippedWithoutEmail":0,"revoked":[],…}. That body is the only thing outside the process that can see how the pass went. The report now carries factReadFailures and revocationFailures; live: healthy 0, broken 1.

2. serverSessionIsLive failing OPEN passed the entire suite. Replacing the lookup with one that swallows its error and returns true — a revoked session honoured whenever the database is unwell — left 184/184 green. This is the plausible break, not a contrived one: the RUNBOOK now documents that a database blip signs people out, and the obvious "fix" for that complaint is a catch in exactly this function.

3. issueServerSession swallowing a failed row write passed the entire suite too, minting a token whose sid points at nothing.

4. (dec3dc5, caught by CodeRabbit on my own fix above, and it was right.) revokeSessionsOrAlert never throws — it swallows the delete's failure and returns failed: true so the already-committed access change keeps its audit row. reconcileAccess only counted exceptions, and the live deps route through revokeSessionsOrAlert, so revocationFailures was structurally always 0 in production and a subject whose session survived was appended to revoked as though it had been ended — the opposite of what the report exists to say. The deps type now admits the optional failed the live implementation has always returned, and the pass counts it. Worth recording that finding 1's fix was itself half-blind until this landed.

2 and 3 are now pinned by sign, not by mechanism — an answer that could not be obtained is never an answer of yes — plus a test that a pruning failure must still let somebody in, so the pair cannot be satisfied by making everything throw. Each was re-run as an asserted-anchor control after committing: all three now RED.

Answers to the specific attacks

Fail-open vs fail-closed — constructed, both directions. With the Session table renamed away under a live session: /dashboard → 307 /signin; /api/auth/session → null and Set-Cookie: authjs.session-token=; Max-Age=0; sign-in during the outage → 302 → /signin?error=Configuration with no cookie set (matches @auth/core/index.js:120-140, type = "Configuration"). Rows unchanged, 3 before and 3 after — nothing was revoked. Fail-closed, correct, and now defended by a test rather than only by a dependency's catch.

Control A, re-run against the Prisma store: RED. deleteAllFor → return 0 fails session-revocation-prisma-store.test.ts. Control F: RED. Every control asserted its anchor (exactly 1 hit), verified the file changed on disk, and restored it byte-exact by SHA.

Performance — no regression, and the first number I measured was wrong. A/B on the same box and database, with the control build proven live (with the lookup removed, deleting the row no longer logs anyone out — 200):

	shipped run 1	shipped run 2	control
/dashboard seq p50	35.1 ms	14.2 ms	14.1 ms
/dashboard conc-20 p50	143.9 ms	160.8 ms	142.3 ms

Run 1's 35 ms was machine noise from concurrent agents, and the repeat refutes it — reporting it as the cost would have been a fabricated regression. Real cost is ~2 Session lookups per authenticated page render ((app)/layout.tsx and the page each call auth(), which next-auth v5 does not memoize — 61 call sites), roughly 1–2 queries on top of ~11 table accesses. Worth knowing: production runs connection_limit=5 per task (scripts/entrypoint.sh:33), so this is ~2 extra pool checkouts per page view. Concurrency p50 tripled in both builds, so the pool ceiling is pre-existing rather than introduced here.

The job runs, and is authenticated. scheduler.tf rule + API destination + IAM verified; JOB_SECRET really is wired into the task from Secrets Manager (ecs.tf:305). Endpoint exercised live: unauthenticated 401, wrong token 401, GET 405, correct token 200 + report. With the registry empty it revoked nobody and the signed-in director still loaded /dashboard — the dangerous direction, reconfirmed.

Migration adds no model. Two indexes only. PLATFORM_GLOBAL still 5, schemaModels still 41 — pins untouched, so no dated rationale is owed. Session was already PLATFORM_GLOBAL, so the "no scope juggling" claim holds. ADR status Proposed (2026-08-20). … is legal: decision-records.test.ts forbids a qualifier on Accepted only.

Remaining gaps — genuine, but beyond my reach to fix safely

1. Nothing alarms on any of this. The EventBridge target has maximum_retry_attempts = 0 and no dead_letter_config, and there is no FailedInvocations alarm on the rule. Worse, and platform-wide rather than this PR's doing: no aws_cloudwatch_metric_alarm in this repository has alarm_actions, and there is no SNS topic — every alarm is an unrouted dashboard state. My fix makes a failed pass observable in the response body; it does not make anyone observe it. I did not add an alarm because terraform is not installed in this environment and I could not validate the HCL, and an actionless alarm would be decoration. "The interval IS their guarantee" should be read as: the interval is the bound, provided somebody is watching — and today nobody is.

2. Triggers 3 and 5 revoke nobody today, and this PR cannot change that. RestrictedIdentity is empty (select count(*) → 0), so isEligible returns unenforced and every subject resolves to registry-unpopulated — the deliberate refusal. Correct behaviour, but it means the two triggers the reconciliation hook exists to cover are inert until the separate registry-seeder work lands. Verified live, not assumed. The refusals are right; the coverage claim is contingent on a change that has not merged.

3. Expired rows are only pruned for people who sign in again. deleteExpiredFor has exactly one call site, inside issueServerSession. Somebody who signs in once and never returns leaves a row that expires and is never deleted; there is no scheduled session cleanup. The comment's "keeps the table from growing without bound" holds for returning users only. Minor, and Session_expires_idx already makes the eventual sweep cheap.

4. The ADR-0015 collision the author flagged is real — One exception object and one operator worklist — and the ADR-0013 fork answered on a new table #101, The institutional policy corpus becomes a signed-digest configuration pack #106 and A seat added on the tenant side is a billable event — and the unit is the person #107 all introduce ADR-0015 (resolved 2026-08-21: main took 0015; this PR is now ADR-0016, the number the index was already reserving. See the merge note at the bottom.)

---

2026-08-21 — origin/main merged in, and this ADR is renumbered to 0016

Merged, not rebased. Three conflicts, plus one collision git could not see.

The collision: ADR-0015 was taken

main landed ADR-0015 as the platform exception object while this branch was writing ADR-0015 for the session-revocation event. The two files have different names, so nothing conflicted in the files themselves — the merge would have gone through clean and shipped a duplicate ADR number, with one decision unreachable by the number every reference uses.

Renumbered to ADR-0016, which the index was already holding open: "Reserved — claimed by another change in the same merge sequence." This is that change — one of the six that each wrote itself an ADR-0015 before the numbers were arbitrated. Checked against every other open PR: nothing else claims 0016 (#129 took 0020, #106 took 0021), so this is uncontested.

The reservation row is removed, because decision-records.test.ts asserts "a reserved number has no ADR file" — a reservation that outlives its ADR fails as loudly as an undeclared hole. Gaps are now exactly {0005}, which is what the index reserves.

Renumbered with it, so nothing points at a file that no longer exists: governance/register.ts's adr.id and adr.file — blocked-architecture.test.ts asserts that path resolves on disk, which is the gate that proves this — plus RUNBOOK.md, PROGRAM-BACKLOG.md, session-revocation.ts, its test, and access-reconciliation.ts. Left alone: every ADR-0015 reference that belongs to main's exception object.

Counts re-derived, not taken from either side. HEAD said 9 of 14, main said 9 of 17; neither was right. Counted the files: 18 ADRs, 10 Proposed.

The other three conflicts

• e2e/support/auth.ts — this branch split signInAs(page, email) out of signIn(page, userName) so a spec can sign in as somebody the product created; main replaced the /dashboard wait with "off /signin and past /workspace" and added an access-pending entitlement assertion. Kept both: the split stays, and main's wait and assertion moved inside signInAs, with the diagnostic naming the address it actually holds.
• orgs/[slug]/members/actions.ts — two unrelated imports on one line. Both kept; both features' call sites verified still present.
• docs/decisions/README.md — the ADR table and the counts, above.

A clean merge that broke a control

session-revocation-is-wired.test.ts asserts per call site that the action changing an assignment's status also revokes that person's sessions, and it pinned the write as db.roleAssignment.update(. main's seat meter wrapped that write in a db.$transaction so the roster row and the meter row commit together — which renames the client to tx without moving the call. Nothing conflicted; the assertion simply went red for a reason unrelated to what it guards.

Widened to (?:db|tx).roleAssignment.update(. The bound that matters is unchanged — still matched against the block for one action — so an update that disappeared from that action still fails.

Verified by negative control rather than by reading it. Committed first, then renamed both tx.roleAssignment.update( call sites to .upsert( and re-ran: "ending or removing a seat revokes the holder's sessions" and "a club roster transition revokes the person whose status moved" both flipped to failing, read per test, not by suite exit code. Restored by explicit path.

Re-derived even where git reported no conflict

• Tenancy pins. 25 TENANT_SCOPED + 5 PLATFORM_GLOBAL + 14 UNENFORCEABLE = 44 = grep -c '^model '. This branch adds no model — merge-base 41, branch 41, main 44 — because its migration adds two indexes to the existing Session. So the counts are main's, verified rather than assumed. registry.ts's doc sentence reads "only 25 of 44 models", matching.
• Migration timestamps. 20260820150000_sessions_are_revocable is unique against main. The only duplicate prefix in the tree is 20260820120000, already duplicated on main; both are applied, so it is left alone.

Gates, from apps/web, each exit code captured before any pipe: prisma generate 0 · tsc --noEmit 0 · jest --ci 0 (137 suites, 2171 passed, 1 skipped, 0 failed) · next build 0.

2026-08-21 (second merge) — a new route met a new registry

main moved twice more while this was being prepared, and the second one
(#96, "Every surface that acts resolves availability, not just the nav")
landed capability-registry/surfaces.ts — a ratchet asserting every API
handler appears in exactly one of two lists, so a NEW endpoint cannot ship
without its author either binding it or writing down that they deferred.

This branch adds /api/jobs/access-reconciliation. The two changes never
touched a common line, so nothing conflicted — the route simply arrived
unaccounted for and surfaces.test.ts went red.

Filed under API_PENDING_BINDING beside /api/jobs/reminders, which is the
same shape: it sweeps every institution at once with no tenant asking, and it
authenticates on the job secret rather than a session, so there is no actor to
resolve a capability for.

Re-gated after both merges: tsc --noEmit 0 · jest --ci 0 (2205
passed, 1 skipped, 0 failed) · next build 0. Tenancy re-measured and
unchanged at 25/5/14 = 44; ADR index still 10 of 18.

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🟡 Moderate · up to 44563

This PR makes sessions server-revocable and adds automatic revocation for membership, assignment, affiliation, identity-link, and provider changes. Merge readiness is reduced because a failed transition can still leave an audit record stating that the action was allowed, with additional bounded test and operational follow-up remaining.

Assert the exact surviving rows.

expect.arrayContaining passes for any superset, so this assertion would also pass if the prune deleted nothing. Line 123 covers the deleted row, so the gap is cosmetic. An exact comparison states the whole claim in one place.

The expires index does not serve any query this cohort adds. Both files declare a standalone index on Session("expires"), but the only expiry query is the per-user prune { userId, expires: { lte: now } }, which Session_userId_idx already covers. A composite index matches the predicate; a standalone expires index would only help a global cleanup sweep that does not exist yet.

194-198: 🩺 Stability & Availability | 🔵 Trivial | ⚡ Quick win

Decide explicitly what a database error means here.

serverSessionIsLive rejects if the database is unreachable. This callback does not catch, so the rejection propagates out of auth(). Protected pages then render a server error instead of redirecting to /signin, and the (app) layout gate never runs. The refusal branch above it returns null for the same class of outcome, so the two failure shapes are inconsistent.

Both choices carry a cost, so state the choice in the code:

• Let the error propagate, and document that a database outage is an error page rather than a mass sign-out.
• Or catch, log, and return null, and accept that a database blip signs every user out.

A third option keeps availability and the audit trail: catch, log with the trigger context, and return null only after a bounded retry.

31-34: 🔒 Security & Privacy | 🔵 Trivial | ⚡ Quick win

Compare the bearer token with a constant-time comparison.

Line 32 compares the token with !==. String comparison returns early on the first differing byte. The secret is 48 random characters, so a remote timing attack is impractical, but the constant-time form costs one helper and removes the class of attack. Compare lengths first, then use crypto.timingSafeEqual.

If api/jobs/reminders uses the same shape, extract one shared helper and use it in both routes.

+import { timingSafeEqual } from "node:crypto"

Add failure visibility for this rule.

The comment at Lines 143-149 states that the fifteen-minute interval is the guarantee for two revocation triggers. That guarantee holds only while the rule actually delivers. Today a failing rule produces no signal: there is no dead-letter queue on the target and no alarm on the rule.

Two additions make the guarantee observable:

• Set dead_letter_config on aws_cloudwatch_event_target.access_reconciliation, so exhausted invocations are retained.
• Add a CloudWatch alarm on the FailedInvocations metric for this rule, and on Invocations falling to zero.

The reminders rule has the same gap, so a shared alarm module would cover both.

The suite runs serially, so fully parallel execution is not the issue. Playwright retries only the failed test in a new worker. The tests at lines 144 and 155 then have no initialized officerContext or managerContext, and the endpoint test also lacks the revoked session state.

revokeSessions filters non-string and empty IDs before deduplication. The catch branch only deduplicates. The two paths therefore return different userIds for the same input.

ADR allocation — CORRECTED. This PR takes ADR-0016

My earlier table missed #104, which also adds an ADR-0015. Six open PRs claim that number: #101, #104, #106, #107, #110, #112.

decision-records.test.ts asserts expect(gaps).toEqual([5]) — the reserved Cognito number is the only permitted gap. So numbering must be contiguous as merged, which makes merge order and number order the same thing.

merge order	PR	number
1	#101 the platform exception object	0015
2	#104 session revocation event emission	0016
3	#107 the billable unit / seat metering	0017 + 0018
4	#110 workspaces are a function of role	0019
5	#112 e2e authentication without a second provider	0020
6	#106 tenant configuration packs	0021

#116 is out of this sequence entirely — it takes no number at all, deferring to ADR-0009, which already exists, is already Proposed, and already owns the same fork (which of RestrictedIdentity / DirectoryPerson / User is canonical), tracked by register row IDENT-002. One record beats two restating one conflict. #115 only edits ADR-0013 and is unconstrained.

#104 is placed second, not last, because it is verified and ready while #106 is blocked on two real defects — a ready PR must not queue behind a stuck one.

Verified the hard way: renaming an ADR to 0021 on a branch whose numbers stop at 0014 yields gaps [5,15,16,17,18,19,20] and CI goes red. Measured, not predicted.

Rename the file and update every cross-reference — the ADR body, the docs/decisions/README.md table, the backlog, code comments, and any test pinning a number. A code comment contradicting the ADR it cites is the one a reader finds first.

Migration timestamp collision — 3 open PRs share 20260820150000

#98 inbound_webhook_receipts, #104 sessions_are_revocable, and #117 knowledge_moves_between_seats.

Git reports no conflict for this. The directories have different names, so a merge is clean and CI is green on both sides. Prisma treats them as two distinct migrations and applies them in lexical order of the full directory name — deterministic, so nothing breaks today.

It matters for two reasons anyway:

1. If two of them ever create the same table, the second fails — a broken deploy rather than a red merge. That is exactly what OSE-initiated onboarding: ADR-0013 decided, and an approval that admits #115 and The onboarding chain gets a spine: its own model, and a delegation that cannot defeat it #116 hit (both CREATE TABLE "OnboardingProposal" at 20260821090000), and it was invisible until someone looked.
2. Ordering becomes a coin-flip on the name suffix rather than on intent, which is the wrong thing for a human to have to reason about later.

Whoever merges second: bump your timestamp to a later value before merging. No code change, just the directory name and any reference to it.

For the record, every collision currently open:

timestamp	PRs
20260820140000	#96, #101
20260820150000	#98, #104, #117
20260821090000	#115, #116 — same table, this one really breaks

1200-1237: 🗄️ Data Integrity & Integration | 🟠 Major | 🏗️ Heavy lift

Write the transition audit only after the compare-and-swap succeeds.

At Lines 1200-1209, requireCapability writes an ALLOW audit event before the update. If the update at Lines 1224-1230 fails with P2025 or another database error, the action reports no transition but the audit trail records an allowed action.

Separate authorization from the successful-transition audit. Record denied authorization attempts immediately. Write the ALLOW transition audit in the same transaction as db.exception.update.

1672-1676: 🚀 Performance & Scalability | 🔵 Trivial | 💤 Low value

Consider an occupant index when the meter is read per person.

The doc comment states that ADR-0017 bills the person, aggregated from these rows at read time. No index supports a filter on occupantKind and occupantId. Such a read falls back to (institutionId, effectiveAt) and then filters in memory. Add @@index([institutionId, occupantKind, occupantId, effectiveAt]) once the read path exists.

1660-1663: 🗄️ Data Integrity & Integration | 🔵 Trivial | 💤 Low value

Pin the referential action on the correction self-relation.

correctsId is optional and declares no onDelete, so Prisma generates ON DELETE SET NULL. If a corrected row is ever deleted, the correction row loses its reference and reads as a standalone withdrawal. That contradicts the stated contract that a correction always says which occupancy it is about.

Declare onDelete: Restrict to make the intent explicit in the database.

-  corrects         SeatMeterEvent?            `@relation`("SeatMeterCorrection", fields: [correctsId], references: [id])
