📝 WalkthroughWalkthroughAdds a complete first-password activation flow. It introduces tenant-scoped invitations, secure operator issuance, Cognito challenge handling, rate limiting, audit logging, activation UI, registry updates, tests, and operational documentation. ChangesFirst-password activation
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟡 Moderate · up to This PR adds an out-of-band activation flow for setting a first password. The current runbook still allows live temporary credentials to be handed over through an unspecified channel, creating a bounded security risk, while smaller integration and operational follow-ups remain around host enforcement, script portability, hashing stability, and focus behavior.

Next.js 15.1 next/jest createJestConfig generated transform .mjs TypeScript moduleFileExtensions official source
💡 Result:
In Next.js 15.1, the next/jest wrapper automatically configures Jest to handle transformations and module resolution, eliminating the need for manual transform or moduleFileExtensions configurations in most projects [1][2]. When you use createJestConfig from next/jest, it internally sets up the necessary Jest transformations using the Next.js Compiler (SWC) [1][3]. This setup includes support for modern JavaScript and TypeScript files, as well as .mjs files [4][5]. Key points regarding your query: 1. Automatic Transformation: next/jest automatically configures Jest's transform option to use the Next.js Compiler [1][2]. This handles .js, .jsx, .ts, and .tsx files, and includes built-in support for .mjs files [4][5]. You do not need to manually add .mjs to your transform object in the Jest configuration [1][2]. 2. Configuration File: The official approach is to export your jest.config.ts (or .js) file by wrapping your custom configuration object with next/jest [1][2]. Example of the standard setup: import type { Config } from 'jest' import nextJest from 'next/jest.js' const createJestConfig = nextJest({ // Provide the path to your Next.js app to load next.config.js and.env files dir: './', }) const config: Config = { coverageProvider: 'v8', testEnvironment: 'jsdom', // Add your custom Jest options here } export default createJestConfig(config) 3. Module Extensions: Similarly, you generally do not need to manually specify moduleFileExtensions. next/jest ensures that the standard extensions (including those required for TypeScript and ESM support) are appropriately resolved [6][3]. If you find that your .mjs files are not being transformed correctly, ensure that you are not accidentally overriding the transform or transformIgnorePatterns in your custom config in a way that excludes these files [1][3]. Because next/jest is designed to handle the complexity of Next.js-specific features, manual overrides are rarely necessary [1][2].

Jest 29.7 .mjs test file plain jest command experimental-vm-modules native ESM official documentation
💡 Result:
To run Jest 29.7 with native ECMAScript Modules (ESM) and.mjs test files, you must enable the Node.js experimental VM modules support [1][2]. Required Steps: 1. Configure Node.js with the Experimental Flag You must pass the --experimental-vm-modules flag to the Node.js binary executing Jest [1][2]. This can be done directly via the command line or through environment variables [1][2]. Command line example: node --experimental-vm-modules node_modules/jest/bin/jest.js Environment variable example: NODE_OPTIONS="--experimental-vm-modules" npx jest 2. Configure ESM Support Jest follows Node.js logic for identifying ESM [1][2]. Ensure your environment is set up for ESM by: - Adding "type": "module" to your package.json [3][4]. - Using the.mjs extension for your test files (which Jest recognizes as ESM by default) [1][2]. - If you need to treat other extensions as ESM, use the extensionsToTreatAsEsm configuration option [1][5]. 3. Manage Code Transforms Jest's ESM support requires that code either has no transforms applied or is configured to output ESM instead of CommonJS (CJS) [1][2]. If you encounter issues, you may need to set transform: {} in your Jest configuration to disable default transformers [1][2]. Important Considerations: - Experimental Status: Jest's native ESM support is labeled as experimental [1][6]. It relies on Node.js APIs that are also considered experimental [1][2]. - Hoisting: Unlike CJS, ESM evaluates static import statements before code execution, meaning jest.mock hoisting does not work in ESM [1][2]. You should use jest.unstable_mockModule instead, though this API is still considered a work in progress [2][6]. - Global jest Object: In ESM, you cannot access the global jest object directly; you must import it from @jest/globals [7].

Next.js Server Actions security public endpoint server action ID forms
💡 Result:
In Next.js, Server Actions marked with 'use server' are treated as public HTTP POST endpoints [1][2][3]. While Next.js provides built-in mechanisms to harden these endpoints, they do not provide authorization or authentication by default [2][4]. Key security features and considerations include: 1. Secure Action IDs: Next.js generates encrypted, non-deterministic identifiers for Server Actions [1][2]. These IDs are recalculated periodically between builds, which helps prevent unauthorized guessing of action endpoints [1][5]. 2. Dead Code Elimination: Server Actions that are not imported or referenced within your application's client-side code are automatically removed during the build process, preventing them from being exposed as public endpoints [1][5]. 3. Built-in CSRF Protection: Next.js protects against Cross-Site Request Forgery (CSRF) by requiring that the 'Origin' header in a POST request matches the 'Host' (or 'X-Forwarded-Host') header [2][5]. If these headers do not match, the request is blocked [5]. Note that this check may be bypassed by non-browser clients (such as curl) that do not send an Origin header [5]. 4. The Security Boundary: Because every Server Action is a publicly reachable POST endpoint, you must treat them as you would any other API route [3][5]. Authentication and authorization must be verified inside the body of every Server Action [1][2][4]. Relying on page-level access control or middleware is insufficient for securing data mutations, as these do not guarantee the caller has permission to perform the specific action [2][6][4]. For secure implementations, always perform authentication (identifying the user) and authorization (verifying if the user is permitted to perform the operation) within the Server Action itself, and validate all input data on the server side [2][6][4].

Enforce the host boundary in activate.
The page guard does not protect the public server action. The action can execute activation without checking onPlatformRouterHost(). Add the same guard before activateAccount so the platform router cannot perform tenant activation.

Both scrypt implementations inherit Node's default cost parameters. Neither call passes N, r, or p, and a stored codeHash records nothing about the cost it was produced with. Because both sides inherit the same defaults, the cross-implementation agreement test cannot detect a change in them; a Node upgrade that altered the defaults would invalidate every outstanding invitation with a green test suite.

Node.js Buffer.from string hex invalid characters behavior truncates does not throw
💡 Result:
When using Buffer.from(string, 'hex') in Node.js, the method does not throw an error when it encounters invalid or malformed hexadecimal input [1][2]. Instead, it processes the string until it encounters an invalid character or an odd string length, at which point it truncates the data and returns a Buffer containing only the successfully processed bytes [1][3]. Key behavioral details include: - Data Truncation: Processing stops immediately upon encountering the first non-hexadecimal character (e.g., 'g' in '1ag123') [1][3]. - Odd Length Handling: If the string has an odd number of hexadecimal characters (e.g., '1a7'), the last incomplete byte is discarded, resulting in truncation [1][3]. - Assumption of Validity: Node.js documentation explicitly states that for the 'hex' encoding, the function assumes valid input [1][4]. The implementation does not include strict validation, as this design choice persists to favor performance and "best effort" processing over strict error throwing [5][6]. Because the method silently truncates rather than throwing a TypeError or other exception, developers are responsible for ensuring the input string is correctly formatted if strict data integrity is required [5][6].

Validate expectedHash before decoding. Buffer.from(expectedHash, "hex") does not throw for invalid hex input, so remove the try/catch. A 64-character valid hash followed by an invalid character still decodes to 32 bytes and can pass timingSafeEqual; the length check does not reject every malformed value.

satvikOS has reached the 50-credit limit for trial accounts. To continue receiving code reviews, upgrade your plan.
Today nobody in the cohort can sign in. An account created by provision-cognito-cohort.mjs sits in FORCE_CHANGE_PASSWORD, cognito.ts refuses that as `challenge-required`, and there was nothing to challenge them with — so a perfect 82/82 provisioning run still leaves 82 people outside. This is the missing half. THE CONSTRAINT THAT SHAPED IT. SES is in the sandbox: 200 a day, one per second, verified recipients only, 0 of 9 DKIM records published. Cognito's invitation mail and ForgotPassword's code are both messages, and neither can reach a student. The send layer landing in #94 does not change that — the sandbox is a state of the AWS account, not a gap in the code. So the question was never which Cognito API; it was how a person proves who they are when no channel to them exists. PD-007 writes the answer down, and activation.ts opens with the threat model rather than leaving it implied. The answer: the Office hands over a one-time code, and that code IS the account's Cognito temporary password. The trust anchor is the handover, said plainly. What the code can do is make sure that handover, and only that handover, becomes an account. WHY THE CODE IS THE TEMPORARY PASSWORD. cognito.tf grants the task role AdminInitiateAuth, AdminRespondToAuthChallenge and AdminGetUser, and deliberately not AdminSetUserPassword. Answering NEW_PASSWORD_REQUIRED is therefore the only way this application can set a first password, and that challenge is reachable only with the temporary password. No new IAM grant, no second secret to exchange. It also means a stolen code cannot produce a session: AdminInitiateAuth with a temporary password returns a challenge and no tokens. ENUMERATION. Every refusal about the address, the invitation or the code is one value with one message — not-on-the-roster, no-invitation, wrong-code, already-used, expired and rate-limited are indistinguishable. In TIME as well: every branch pays exactly one scrypt derivation, against a decoy when there is nothing real to check, and the whole action is padded to a 900 ms floor. activation-timing.test.ts asserts both — the derivation count structurally, and the measured spread against a tolerance calibrated to one derivation on the machine it runs on rather than a millisecond figure that means different things on a laptop and a runner. The password answers are the exception, and the ORDER of the checks is what keeps that safe: "too short" and "they do not match" are decided before the address is looked at, so they are a function of what the person typed and of nothing else. ELIGIBILITY, and one asymmetry that is deliberate. Activation passes requireRegistry: true, which sign-in does not. An empty or unsealed registry at sign-in means an unenforced gate for people who already have accounts; here it would mean anyone holding any code could mint one. This path creates access, so it fails closed — the direction that costs an outage rather than an intruder. The three-fact RegistryLookup from #113 is used as-is; nothing here re-reads the roster by a second path. SINGLE USE, TWICE AND INDEPENDENTLY. A conditional UPDATE only one caller can win, and Cognito leaving FORCE_CHANGE_PASSWORD. Neither depends on the other. The code is verified BEFORE the invitation is consumed, so a stranger with a wrong code cannot burn somebody else's invitation — a denial of service delivered by the replay defence. RATE LIMITED in two places. A rolling per-invitation counter in one UPDATE with a CASE, because read-then-write loses attempts under concurrency; and an in-process per-client limiter that makes a flood cheap to refuse. The in-process one is keyed on the client address and NOT on the email, on purpose: keying on the email would let an attacker spend a victim's budget from anywhere and leave the victim refused on the one page they must use. PASSWORD POLICY. Stated once, shown live as the person types, checked on the server, and held to the pool: password-policy.test.ts PARSES cognito.tf and fails if the two disagree, including the symbol set and the temporary-password validity that bounds the invitation TTL. A UI that accepts what Cognito rejects is a dead end at the one moment the person has no second attempt. SESSIONS. Setting a password revokes. The only sessions a person with no password can have are dev-login sessions — an address plus a shared passphrase, with no proof of ownership — and choosing a password is the moment their own claim to the account begins. The mechanism is a delete from `Session`, the register #104 makes authoritative, rather than a second watermark of our own; until #104 lands nothing reads that table, and the code says so. The control carrying the weight today is that activation issues NO session at all: the person signs in fresh, through the path everybody else uses. ISSUING. scripts/activation-invitations.mjs runs under an OPERATOR's credentials. It does NOT create accounts — #108 owns that — it installs a code as an existing account's temporary password, then reads the account back and refuses unless the pool left it in FORCE_CHANGE_PASSWORD, because RESET_REQUIRED would send the person to an emailed recovery code that cannot be delivered. Codes are written to one file at mode 0600 and to nowhere else; stdout goes to scrollback, to shell transcripts and to build logs. The code is never stored: the table holds scrypt(code, salt). The script and the application are two implementations of one format, because one is .mjs and the other is TypeScript. activation-code-agreement.test.mjs loads both and fails if they disagree on the alphabet, the hash of the same input, the password rules or the lifetime — drift there would lock out the whole cohort, one person at a time. A FAULT IS A REFUSAL. Every unexpected exception is caught at the boundary and answered as `refused`, because on this surface a distinguishable failure IS the vulnerability: the audit write happens only when an invitation exists, so a database fault would otherwise render as a 500 for an invited address and as the ordinary refusal page for a stranger — the one question this flow is built to refuse to answer, given away by a transient fault nobody was watching for. The fault is logged with the address, server-side, where it can be acted on. That catch is deliberately unable to lie about a completed activation. The two steps that run after Cognito accepts — the revocation and the ALLOW audit row — are individually guarded where they are, so nothing between a successful setPassword and `activated` can throw. A revocation that failed is written into the audit reason rather than reported as success; #104's own post-review fix was that lesson in the other direction. VERIFIED. tsc, jest (1962), test:isolation against a real PostgreSQL, and next build. Twenty-two negative controls were run: each break was applied with an asserted anchor, watched go red, reverted, and watched go green. Three of them found real gaps and are why the suite is bigger than it was — the sequential replay was caught by consume alone, so neither replay defence was individually pinned; the measured timing bound was two derivations wide, which is exactly one derivation too wide to catch a branch that skips one; and the first version of the fault guard still let a throwing ALLOW audit write turn a set password into "that did not work". REBASED three times while this was in flight — onto #113 (the sealed registry, whose three-fact RegistryLookup this now uses as-is), #94 (the SES send layer, which does not change the sandbox this design is shaped by) and #119 (which renamed the unit and rebuilt the sign-in page, so the "New here?" entry was re-applied to its new structure rather than merged into the old one). The naming commit was dropped: #119 landed the same correction first. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Map.set on a key that already exists does not move it, so the front of the window map is the FIRST-SEEN key rather than the oldest window. Evicting from the front therefore dropped an exhausted client's own record before any of the forged addresses that displaced it: twenty attempts, a flood of rotating X-Forwarded-For values, and a fresh window. charge() now deletes before re-inserting, so map order really is oldest-window- first, and eviction skips any window that is at or above the limit. Age is the tie-break among windows that are refusing nobody, not the criterion. When every window held is refusing somebody the cap still holds by dropping the oldest -- reaching that state costs the attacker limit x maxKeys requests to buy back one window. The suite's 'drops the OLDEST windows when it evicts' case asserted the defect as intended behaviour; it is replaced by the control that reproduces the attack.
A negative control found the delete-before-set entirely untested: removing it left all twelve cases green. This is the case that discriminates -- a key seen first whose window re-opened last must NOT be read as the oldest window.
… first
Four findings on scripts/activation-invitations.mjs.
The output file was written with writeFileSync(..., {mode: 0o600, flag: 'w'}).
mode is applied by the kernel only on CREATION, so a re-run into the same --out,
or a path an operator touched, put 82 live temporary passwords into whatever
permissions that file already had. It is now opened with 'wx' and fchmod-ed on
the descriptor, and a path that exists is refused rather than replaced.
It was also opened only AFTER the whole loop of pool mutations, so a missing
directory or a read-only volume lost every code that had just been installed
while leaving every account in FORCE_CHANGE_PASSWORD with a password nobody
knew. It is now opened, proved and given its header before the first
AdminSetUserPassword, and each code is appended and fsync-ed as it is issued.
AdminSetUserPassword ran before the database row was written. A failure in
between discarded the code while the account's temporary password WAS that code
-- and under --rotate the row still held the previous hash, so the old code
verified, consume() spent the invitation, the pool refused, and setPassword
mapped that to 'refused', the one reason that does not restore. Burnt for good.
The row is now written FIRST and already expired, and given its real expiry only
once the pool has confirmed FORCE_CHANGE_PASSWORD; every partial failure now
leaves an invitation nobody can redeem, which a re-run repairs. The catch names
the last step that succeeded and prints the remedy, including the one case where
a live credential is loose.
planInvitations promised 'reissue' for a redeemed invitation under --rotate that
the run always refused as CONFIRMED. The plan now takes each address's Cognito
UserStatus -- read on the dry-run path too -- and can say 'refuse'. It still
plans a rotation for the redeemed-but-never-confirmed case, which is a real
state and the only remedy for it.
The doing half is now issueOneInvitation, behind ports, so the ordering and
every partial failure are asserted rather than described.
Removing fchmodSync left the suite green, because a default umask of 022 takes nothing out of 0600. The case that discriminates sets a umask that does.
Two lows. ActivationInvitation had no index that could serve findInvitation's read. It filters on emailNormalized alone, and both existing indexes lead with institutionId -- a btree cannot seek on a predicate that names only the second column. So the redemption path's 'one indexed read', which the constant-time argument in activation.ts is sized against, was a sequential scan on a table reached from a public unauthenticated form. Additive migration, one index. lookupRegistry ran a different NUMBER of queries depending on the address: a roster member returned after findMany + seal, a stranger additionally paid for a table-wide count. Slower meant 'not on the list', which is the informative direction, and only the 900ms response floor hid it -- on the activation form only, since sign-in has no floor. The count is now an existence probe (LIMIT 1 rather than a tally, so it is cheap enough to run unconditionally) and it joins the other two reads. Three queries, same shape, whoever is asking.
Two lows an adversarial pass found, neither of which any test could see. FOUR of the five meaningful columns on the AuditEvent row this flow writes were unasserted. Replacing `outcome: entry.outcome` with a hard-coded "ALLOW" left 1,988 unit tests and 107 isolation tests green -- a refused attempt would have been written into an append-only log as a successful one and nothing would have said so. `reason`, `resourceId` and the address in `metadata` survived the same treatment. Only the ALLOW row had ever been looked at, so only the ALLOW row was held, and the refusals are the half an operator actually reads: the response says nothing on purpose, and the trail is where the real reason is kept. Two tests now cover the DENY row -- its outcome, action, resource, address and reason -- and the ALLOW assertions gain the three columns they were missing. All five mutations go red and restore green. The multi-refusal test compares SORTED reasons: `occurredAt` comes from one `now()` per attempt, two attempts can share a millisecond, and an assertion that depends on which of two equal timestamps the planner returns first is a test that fails once a month for a reason nobody can reproduce. And `eligibility.ts` still said "NOTHING PASSES IT TODAY" of `requireRegistry`, naming first-time activation as the path that would pass it "on another branch". This is that branch, and it landed -- so the comment claimed a boundary was unenforced at the one call site where it IS enforced. That is the inverse of the defect the same paragraph warns about, and it is a comment, so a rule in prose would recur. `eligibility.test.ts` now scans the tree for call sites that pass the option -- comments stripped, so a file that merely describes it is not mistaken for one that passes it -- and fails if the paragraph does not name each one. Both directions negatively controlled: removing the name goes red, and so does removing the call, which is what stops the gate passing vacuously.

3dc56fe was pushed to this branch and GitHub created no check run for it -- zero on /commits/3dc56fe/check-runs, while pull_request CI fired for three other branches in the same ten minutes. Nothing about that commit explains it: it touches two test files and one comment, and the same push credential triggered the run on a7275a2 an hour earlier. An empty commit is the smallest thing that re-fires `synchronize` without changing what is being reviewed. If this one runs, the gate is green on content identical to 3dc56fe.

Add an address-only index for RestrictedIdentity.
ActivationInvitation bounds the unscoped query with take: 3 and rejects every result with more than one row, so cross-tenant invitations do not cause nondeterministic redemption. However, restricted-registry.ts queries RestrictedIdentity by status and emailNormalized without institutionId. Add @@index([emailNormalized]) to avoid a sequential scan on this pre-session lookup.

The gap this closes
A person provisioned into Cognito by #108 lands in
FORCE_CHANGE_PASSWORD.cognito.tsrefuses that aschallenge-required, and there was nothing tochallenge them with — no
NEW_PASSWORD_REQUIREDscreen, noForgotPassword, norespondToAuthChallengeanywhere outside Terraform and a test. A perfect 82/82provisioning run still leaves 82 people unable to sign in. This is the missing
half: a real New here? → Set your password page at
/signin/activate.The constraint that shaped the design, and the answer written down
SES is in the sandbox — 200/day, 1/s, verified recipients only, and 0 of 9
DKIM CNAMEs published. Cognito's invitation mail and
ForgotPassword's code areboth messages, and neither can reach a student. The send layer that landed in
#94 does not change this: the sandbox is a state of the AWS account, not a gap
in the code, and #109 refuses to file for production access until DKIM verifies.
So the question was never which Cognito API. It was how a person proves they
are the right person when no channel to them exists. The answer is written
down in
docs/decisions/PRODUCT-DECISIONS.mdPD-007, and the threat modelopens
src/lib/auth/activation.tsrather than being left implied.The decision: the Office hands over a one-time code out of band, and that
code is the account's Cognito temporary password. The trust anchor is the
handover — said plainly, because dressing it up would be worse than admitting
it. What the code can do is ensure that handover, and only that handover,
becomes an account.
Why the code is the temporary password rather than an envelope for one.
cognito.tfgrants the task roleAdminInitiateAuth,AdminRespondToAuthChallengeandAdminGetUser— and deliberately notAdminSetUserPassword. AnsweringNEW_PASSWORD_REQUIREDis therefore the onlyway this application can set a first password, and that challenge is reachable
only with the temporary password. No new IAM grant is needed. It also means
a stolen code cannot produce a session:
AdminInitiateAuthwith a temporarypassword returns a challenge and no tokens.
It improves rather than gets rewritten. When production access lands, the
same invitation gains a delivery channel — mailed through #94's send layer
instead of carried. The page, the table, the redemption path and the threat
model are unchanged.
No ADR number was taken, on purpose
ADR-0015is claimed by #104, anddecision-records.test.tsfails on any gapexcept the reserved
0005— so taking0016would have broken CI for whicheverof us merged first, and taking
0015guarantees a conflict. This is a questionof intent rather than architecture, which is what
PRODUCT-DECISIONS.mdisfor, and it supersedes by addition. PD-007 it is.
The security properties, and how each is held
activation.ts— onerefusedvaluetoEqualon the whole valueUPDATE, and Cognito leavingFORCE_CHANGE_PASSWORDrequireRegistry: trueactivateAccountOn timing
Equal answers are worth nothing if the two take measurably different times.
activation-timing.test.tsasserts it two ways: structurally, that everybranch performs exactly one scrypt derivation (counted, cannot flake), and
measured, that the spread across all ten branches is smaller than one
derivation on the machine the test is running on — calibrated in the test
rather than written as a millisecond figure that means one thing on a laptop and
another on a loaded runner. Measured spread today is ~2 ms against a ~22 ms
derivation and a 900 ms floor.
The client rate-limit branch is deliberately excluded and the reason is in the
code: it does not depend on the address, so it distinguishes no two addresses.
On eligibility, and one asymmetry that is deliberate
Activation passes
requireRegistry: true; sign-in does not. An empty orunsealed registry at sign-in means an unenforced gate for people who already
have accounts. Here it would mean anyone holding any code could mint one. This
path creates access, so it fails closed — the direction that costs an outage
rather than an intruder.
The three-fact
RegistryLookupfrom #113 is used exactly as it is, sealincluded, and there is no second roster reader. Two new tests pin the
asymmetry: a populated-but-unsealed registry refuses a non-roster address
here while allowing at sign-in, and someone who is on an unsealed roster is
still admitted — fail-closed must not mean fail-always.
A fault must not become an oracle either
Every unexpected exception is caught at the boundary and answered as
refused.On this surface a distinguishable failure is the vulnerability: the audit
write happens only when an institution is known — that is, only when an
invitation exists — so a database fault would render as Next's error page for an
invited address and as the ordinary refusal page for a stranger. That is the one
question this flow exists to refuse to answer, given away by a transient fault
nobody was watching for. The fault is logged with the address, server-side.
That catch is deliberately unable to lie about a completed activation. The
two steps that run after Cognito accepts — the revocation and the ALLOW audit
row — are individually guarded where they are, so nothing between a successful
setPasswordandactivatedcan throw and send somebody back to spend aninvitation that is already spent. A revocation that failed is written into the
audit reason rather than reported as success; #104's own post-review fix was
that same lesson in the other direction.
Sessions: it revokes, and the mechanism is #104's
Setting a password revokes prior sessions. The only sessions someone with no
password can hold are
dev-loginsessions — an address plus a sharedpassphrase, with no proof of ownership — and choosing a password is the moment
that person's own claim to the account begins.
The mechanism is a delete from
Session, the register #104 makesauthoritative, not a second watermark of our own. Until #104 merges nothing
reads that table and the delete has no observable effect; the code says so
rather than implying otherwise. The control carrying the weight today is that
activation issues no session at all — the person signs in fresh, through the
path everybody else uses. That also removes any race between ending the old
session and issuing a new one, and it stops a successful password change from
being reported as a failure when identity linking refuses for its own reasons.
src/lib/auth/session-revocation.tsis not touched, and neither isauth.ts. No conflict with #104.Issuing — and it does not provision
scripts/activation-invitations.mjsruns under an operator's AWScredentials, never the task role's. It does not create accounts — #108 owns
that — it installs a code as an existing account's temporary password, then
reads the account back and refuses unless the pool left it in
FORCE_CHANGE_PASSWORD.RESET_REQUIREDwould send the person to an emailedrecovery code that cannot be delivered; that difference is a documented API
detail this repository cannot verify from here, so it is checked as a
postcondition instead of assumed.
Codes go to one file at mode 0600 and nowhere else — stdout goes to
scrollback, to shell transcripts and to build logs. The code itself is never
stored: the table holds
scrypt(code, salt).The script and the application are two implementations of one format, because
one ships as
.mjsand the other is TypeScript compiled by Next. Thatduplication is the most dangerous thing here — drift would mean every code the
Office hands out is refused, discovered one person at a time — so
activation-code-agreement.test.mjsloads both and fails if they disagreeon the alphabet, on the hash of the same input, on the password rules, or on the
lifetime.
Password policy matches what Cognito actually enforces
password-policy.test.tsparsescognito.tfand fails if the two disagree— minimum length, each character class, the exact symbol set (
_is a Cognitosymbol;
-is not, which is why the code format uses_), and thetemporary-password validity that bounds the invitation TTL. A UI that accepts
what Cognito will reject is a dead end at the one moment the person has no
second attempt.
A 2.2 MB page I shipped and then measured
Every card carries a control for moving it, and the seats it may move to depend on who is looking: ten for a club officer, every seat at the institution for OSE. The first version handed each card its own expanded copy. Measured on the seeded roster (26 clubs, 235 seats), twelve cards on the page:
<option>elementsNothing was broken and no test failed — the cost was in the shape of the data, not in the code, and no reviewer would have caught it in a diff. Fixed in two halves because they are two problems: a page-level context sends the list once instead of once per card, and a club-then-seat pair of selects keeps only the chosen club's seats in the DOM.
e2e/memory-page-weight.spec.tsnow holds a budget per card — an absolute page budget passes on an empty page and breaks when another spec adds a card, which makes it a flake rather than a guard.Verification

RegistryLookupthis now uses as-is, with two tests added for the asymmetry),#94, and #119. All 22 controls were re-run after the last rebase and
still behave — one of them failed its own anchor check first, loudly, because
#119 had reformatted the line it patches. That is the harness working: a
scripted break that silently matches nothing is how a control harness ends up
printing STILL GREEN over unmodified code.
CodeRabbit and Greptile both returned nothing on this PR — CodeRabbit is rate
limited and Greptile's trial credits are exhausted — so the self-review below
stands in for them, and it did find things.
Twenty-two negative controls, each broken → RED → restored → GREEN
Every break was applied by a script that asserts its anchor and fails loudly
if it does not match, because a scripted edit that silently does nothing is
how a harness ends up printing STILL GREEN over unmodified code.
Three of these found real gaps, and are why the suite is bigger than it was:
nothing observable, because
consume's conditional update caught thesequential replay on its own — so neither replay defence was individually
pinned, and both could have been removed one refactor at a time with the suite
green throughout. A test that asserts

one: the tolerance was two derivations wide, which is exactly one derivation
too wide to catch a branch that skips one. Tightened to one, re-verified, and
run three times for stability.
Writing the guard was not enough: the first version of it still let a
throwing ALLOW audit write turn a set password into "that did not work", and
control 22 is what caught that. The suite went red on my own fix before it
went green.
The naming correction — dropped, because #119 landed it first
This branch carried a commit renaming Office of Student Experience to
Engagement in the four places that held the string. #119 merged the same
correction while this was in review, so that commit was dropped on rebase
rather than re-applied. Verified after rebasing:
grep -rn "Office of Student Experience"over the tree returns nothing. Nothing was lost and nothing isduplicated.
#119 also rebuilt the sign-in page. The New here? entry was re-applied to
its new structure — under the institution form, where the question arrives —
rather than merged into the layout it replaced.
