halkyon_base: a Serverpod module for sign-in, accounts and instance basics
What every Halkyon server has, taken from Halkyon Learn's: anonymous,
GitHub and email-code sign-in with their endpoints, an account's ways
in and its deletion, the pruning of abandoned anonymous people, of
sign-up attempts and of expired codes, and the instance's basics (the
sign-in ways offered, the source link, the minimum app build, where
people's data and its backups are). Endpoints sit under the nickname
`base`. A host configures it in one place before its pod starts: its
name for the mails, its source link, its minimum build, and hooks that
delete its own data with a person.
The tables keep Learn's names, columns and indexes, so a host moving
onto the module migrates nothing but version rows. Server package under
the SSPL, client under the AGPL, as Learn's are.

refactor(profile): handles and profiles move into halkyon_base
People's public profiles are the instance's register's (ADR 0016), so
the module now holds them: the public_profile table (unchanged, so
Learn's migration records versions only; devices get the table empty,
as they hold every module's tables), the profile and profiles
endpoints under `base`, the handle rules, the link checks and the page
at /@handle, whose foot names the app as the host's configuration says
(profilePageNote). Deleting a person deletes their profile in the
module's core.
Hosts read profiles through the module (profileOf, profilesOf,
personWithHandle, fixHandle; saveProfile for their tests), behind an
AccountRegister that is this server's own database for now. Learn's
feedback, discussions and publishing ask it; publishing fixes the
handle just before it writes the release, outside its transaction.
Explore still joins the table in its search, so Learn holds the
register wherever it runs. Learn's app calls the module's endpoints;
a profile not found is ProfileNotFoundException. Todo's database gets
the table too (it was never deployed).

feat(auth): a password with TOTP on the register, and resets
The register's side of signing in with an address, a password that never
leaves the device (SRP-6a) and a code from an authenticator (ADR 0017),
with members forwarding every step through AccountRegister:
- password.set: salt, Argon2id's costs, SRP's verifier, the public keys
and the private keys wrapped twice, all made on the device; with the
address a mailed code proves, an anonymous person becomes identified
under their ID. It signs in once an authenticator is confirmed.
- passwordSignIn.begin and complete: SRP's two steps with a TOTP or
recovery code. An address nobody has is answered from a decoy key as
an account would be; every wrong credential is refused alike.
- authenticator: secrets sealed under totpKey (XChaCha20-Poly1305, bound
to their row), each code accepted once, ten recovery codes with the
first, the last one kept.
- accountRecovery: a lost authenticator reset 72 hours after the
password and a mailed code or the recovery phrase ask, a lost password
set anew with the phrase's signature, or the account reset with new
keys 72 hours after a mailed code asks; a mail at each start, a
sign-in calling it off.
- An account with a password no longer signs in by a mailed code or
GitHub; no new GitHub account is linked where passwords are offered,
and from GITHUB_SIGN_IN_ENDS GitHub signs nobody in and its IDs go.

fix(auth): count per-network limits by the visitor behind Caddy
Every per-network limit counted by the connection's address, which behind
Caddy is Caddy's for everyone: new anonymous accounts, codes by mail and
password sign-ins were each limited for the whole instance.
`networkOf` (now `common/network.dart`) takes the last address of
X-Forwarded-For, the one the proxy saw itself, for a connection from a
proxy the operator trusts (`TRUSTED_PROXIES`, which deploy/compose.yaml
sets to Caddy's fixed address); otherwise, or where that is no address,
the connection's. Never the Forwarded header, which Caddy passes on as
sent, so never Serverpod's `remoteInfo`. A value that isn't addresses
stops the server as it starts.
Serverpod's own limit on anonymous accounts counts by the connection's
address too and can't be told otherwise, so it is off; the anonymous
endpoint counts them itself, 30 an hour per network as before.

fix(auth): a reset waits while its owner is held out, and devices show it
The full reading's H1: an owner could be kept from calling a reset off, and
the reset then went through. Whoever knew the password and had the mailbox
asked an authenticators' reset and kept the codes waiting, so the owner's
sign-ins were refused until it took effect; whoever had the mailbox filled
the address's proofs ceiling from three networks and completed an account
reset. Now every hold-out of the owner after a reset was asked (a wait
that begins, an attempt a wait refuses, a sign-in or proof refused by the
address's ceiling) moves the account's resets not carried out to take
effect no sooner than 72 hours after it ends (pushOutResets). A reset
carried out (the password alone signing in until an authenticator is
confirmed) is never pushed, nor a lapsed one brought back.
Signed-in devices are told too: SignInWays carries when a waiting reset
of each kind takes effect, the account section shows them with Call it
off, which takes the owner's proof (password and code; password.
callOffResets, forwarded by members) and calls every reset off, as no wait
holds a signed-in owner's proof back. Texts in English and German.

fix(auth)!: proofs are bound to the instance the device addresses
Nothing tied a sign-in's proof to the instance it was made for: an
instance a person was lured into adding could pass A, M1 and the code on
to the real register and get a session there, and pass a phrase's proof
on with a password of its own in place of the person's (the second
reading's M6). SRP's identity is now a label, the challenge's ID and
the host the device addressed (passwordIdentity, in halkyon_base_client
and halkyon_base_server alike), and the phrase's proof signs that host,
what it is for (an authenticator's reset or a new password) and the new
password's digest (key proof v2). Every proving call carries the host;
in production it must be the server's apiServer.publicHost (otherwise
otherInstance, which the app shows as an instance it can't trust), in
development any; a member forwards its own. The tests prove that a
relayed sign-in, a proof for another host or purpose, and a swapped
password are refused, nothing changing.

The identity also gains a purpose and the digest of what a proof sets,

feat(base): mending a broken SimpleLogin link with the handle and the recovery phrase (ADR 0020, D7)
Someone whose SimpleLogin identity is new to the register but who has an
account ("I already have one") names their handle and proves the
account's recovery phrase; the new identity takes the old one's place.
- `simpleLogin.beginMend(attempt, handle)`: the keys wrapped under the
phrase's key, the public keys and a nonce, for the account with that
handle (whatever its case). Only an account with keys and a SimpleLogin
identity is mended, a link it had, as nobody adds SimpleLogin signed
out (D10); a handle nobody has, or any other account's, gets a decoy
from `signInDecoyKey`, the same each time. At most 10 an hour per
handle and 30 per network.
- `simpleLogin.mend(attempt, proof)`: the phrase's proof for `mendLink`,
binding the attempt (`mendLinkDigest`, on both sides), so a proof
relayed from another sign-in links nobody's identity but the device's
own; checked for the waiting identity first, which leaves the proof
unspent. Every session of the account ends, in every service, and the
sign-in stands ten minutes for a change, such as a lost password.
- SimpleLogin needs `SIGN_IN_DECOY_KEY` alone of ADR 0017's three keys
(`signInDecoyKeyOf`); `addInstanceRoutes` stops a server with a
SimpleLogin app and without it (`checkSimpleLoginMending`).
- Members ask the register for both; `RemoteRegister` and the instance
API carry them.

feat(base): the changes of SimpleLogin accounts' keys, each with the password and a fresh sign-in (ADR 0020, D20)
Every change takes the password's proof by its own proof key (the
recovery phrase's for a lost password) and a SimpleLogin sign-in of the
last ten minutes on the device (`KeysOwnerProof`, its attempt), as ADR
0017's take the password and a code. The sign-in is checked before the
proof and taken with the change, so a wrong proof leaves it standing and
each sign-in serves one change.
- `keys.set(attempt, setup, handle?)`: the first keys of an account that
SimpleLogin was added to (anonymous before, or signing in with GitHub
or a code), with the handle where it has none; the sign-in alone, as
there is no password to prove yet.
- `keys.changePassword`, `keys.beginPhrase` and `keys.resetPassword` (a
lost password, with the phrase): every other session ends, in every
service, as ADR 0017's change has it.
- `keys.setRecoveryKeys`: a new phrase.
- `account.delete(keysProof)`: an account without SRP's verifier deletes
itself with the proof and the sign-in; `requireOwnerToDelete` no longer
asks such an account for SRP.
- `newKeysPasswordDigest` on both sides, held to each other by a test; a
challenge purpose of its own for the phrase's proof while signed in.
- Members ask the register for all of it; `RemoteRegister` and the
instance API carry the five new operations and the deletion's proof.

feat(base): a reset of the keys without the phrase, and the keys' proof key for a password that signs in (ADR 0020, D31–D34)
An account that signs in with SimpleLogin alone, its password and its
recovery phrase both lost, asks for new keys with a SimpleLogin sign-in
(`keys.startReset`); another sign-in carries it out 72 hours later
(`keys.completeReset`, `notDue` with when before), with the same keys
rewrapped where the device still holds them (D33). No mail: every
signed-in device shows it, and any right proof of the password's or the
phrase's key, or a mend, calls it off; `keys.callOffResets` takes the
password's proof alone (D32). The row is ADR 0017's account reset of kind
`account`, so no migration; ADR 0017's reset by mail now takes only an
account whose password signs in.
An account with ADR 0017's password that added SimpleLogin had keys but
no proof key, so no new device signed in with SimpleLogin could open
them: `password.setProofKey` sets the one that same password makes, with
the owner's proof binding it (D34), and ADR 0017's new password takes it
away. Only an account that signs in with SimpleLogin alone changes
through `keys`. `simpleLogin.complete` says whether the password signs
in, whether the keys have the proof key, and when a reset takes effect.

proofKeyDigest,

fix(auth)!: proofs are bound to the instance's whole base URL
SRP's identity and the recovery phrase's proof carried the host alone, so
instances on one host under another port, path or scheme could relay each
other's proofs (the full reading's device low 4). Both now carry the base
URL the device addresses, written alike on both sides
(canonicalInstanceUrl: scheme and host in lower case, the port only where
it isn't the scheme's own, the path ending in /); the register takes its
own public scheme, host and port (Serverpod serves at the root), a member
the URL it names, development anything.
The identity also gains a purpose and the digest of what a proof sets,
both empty so far (signing in), with the framing for a new phrase's and an
authenticator's digest beside the new password's: the owner's proofs bind
them next. Cross-tests hold both sides to the same bytes. OwnerProof's and
DeletionProof's host, and every endpoint's, become instanceUrl.

feat(auth): a password with TOTP on the register, and resets
The register's side of signing in with an address, a password that never
leaves the device (SRP-6a) and a code from an authenticator (ADR 0017),
with members forwarding every step through AccountRegister:
- password.set: salt, Argon2id's costs, SRP's verifier, the public keys
and the private keys wrapped twice, all made on the device; with the
address a mailed code proves, an anonymous person becomes identified
under their ID. It signs in once an authenticator is confirmed.
- passwordSignIn.begin and complete: SRP's two steps with a TOTP or
recovery code. An address nobody has is answered from a decoy key as
an account would be; every wrong credential is refused alike.
- authenticator: secrets sealed under totpKey (XChaCha20-Poly1305, bound
to their row), each code accepted once, ten recovery codes with the
first, the last one kept.
- accountRecovery: a lost authenticator reset 72 hours after the
password and a mailed code or the recovery phrase ask, a lost password
set anew with the phrase's signature, or the account reset with new
keys 72 hours after a mailed code asks; a mail at each start, a
sign-in calling it off.
- An account with a password no longer signs in by a mailed code or
GitHub; no new GitHub account is linked where passwords are offered,
and from GITHUB_SIGN_IN_ENDS GitHub signs nobody in and its IDs go.

fix(auth)!: a first password takes a fresh proof of the account's way in
The fourth reading's first finding: password.set took a session alone,
so whoever took one made a GitHub-only account, or an address account
without a password, theirs for good (their address or password, their
authenticator; GitHub then refused the owner).
- An account with an address proves it anew: a code mailed to that
address for this (EmailCodePurpose.firstPassword, its own mail), never
the session alone, a code asked for anything else, or another address.
- An account that signs in with GitHub alone does it within 10 minutes of
a GitHub sign-in (the session's method and creation time, where the
session lives; members tell the register), refused signInAgain before
any code is used; the address it adds is proved as before.
- Anonymous people still become identified with a code to the address
they add.
The app mails the code to the person's own address (asking for it where
the device doesn't know it), offers a password right after a GitHub
sign-in (D2's "at their next sign-in") before the person's app, and asks
for a GitHub sign-in anew when the instance refuses an older one, keeping
the code typed.

feat(app): a lost password with the recovery phrase in SimpleLogin's sheet (ADR 0020, 7)
An account that signs in with SimpleLogin opens its keys with its
password. Where that is lost, the unlock step's "Forgot your password?"
opens one step: the recovery phrase, and a new password twice. There is
no address and no code: the SimpleLogin sign-in of a moment ago stands
for them (D20).
- The device opens the keys with the phrase (`keys.beginPhrase`) and
wraps them under the new password (`AccountCrypto.newKeysPassword`).
It then signs the phrase's proof bound to that password
(`signKeysResetProof`), which `keys.resetPassword` takes with the
sign-in. The keys stay, and every other session ends.
- A phrase that doesn't open the keys is refused on the device, and the
instance gets no proof to count. Two passwords that differ are
refused before anything is sent.
- The gateway's `beginPhrase` and `resetPassword` run on the account's
own session, not yet the device's. The repository's `resetPassword`
ties them together, and the cubit and sheet have their `forgot` step.
Three texts are new, in English and German.
- halkyon_base_server exports `isKeysPassword` for the interop test,
which checks against the register's checks, with real libsodium, what
the device sends.

feat(base): handles hidden until their people go public, every answer about a new handle counted (ADR 0020, D5)
A handle's page and profiles.byHandle answer as for a handle nobody has
until its person goes public: a handle fixed by a publish, or a display
name, a bio, a link or an avatar (isPublic). A person's own profile, and
the host's own lookups (personWithHandle), are unchanged.
So every answer about a new handle now tells that an account has it,
and countHandleCheck counts them together on the register, 30 an hour
per person (or attempt) and 60 per network, refused beyond with
ProfileRefusal.tooManyHandleChecks: profile.checkHandle and saving a
profile with a handle new for the person, simpleLogin.checkHandle and
signUp, keys.set with a handle, and Halkyon Learn's inbox.block and
unblock, which look people up by handle. A person's own handle and what
is no handle aren't counted. The SimpleLogin limiters of commit 3 give
way to it, so a network's 60 are shared between people signed in and
people new. The register's checkHandle, saveProfile,
signUpWithSimpleLogin and setFirstKeys carry the visitor's network from
the member that asked.
Halkyon Learn's handle dialog words the new refusal (English, German).

refactor(profile): handles and profiles move into halkyon_base
People's public profiles are the instance's register's (ADR 0016), so
the module now holds them: the public_profile table (unchanged, so
Learn's migration records versions only; devices get the table empty,
as they hold every module's tables), the profile and profiles
endpoints under `base`, the handle rules, the link checks and the page
at /@handle, whose foot names the app as the host's configuration says
(profilePageNote). Deleting a person deletes their profile in the
module's core.
Hosts read profiles through the module (profileOf, profilesOf,
personWithHandle, fixHandle; saveProfile for their tests), behind an
AccountRegister that is this server's own database for now. Learn's
feedback, discussions and publishing ask it; publishing fixes the
handle just before it writes the release, outside its transaction.
Explore still joins the table in its search, so Learn holds the
register wherever it runs. Learn's app calls the module's endpoints;
a profile not found is ProfileNotFoundException. Todo's database gets
the table too (it was never deployed).

feat(auth): change the password and the recovery phrase while signed in
ADR 0017, step 3. `password.beginChange` and `password.change` take the
old password's SRP proof and a TOTP or recovery code, and the same keys
wrapped under the new password; a session alone changes nothing, and an
account without a confirmed authenticator is told to set one up first.
`password.setRecoveryKeys` replaces the keys' wrapping under the
recovery phrase for a TOTP code, so a device holding the keys can make
a new phrase.
A change of password ends every other session of the account in every
service of the instance; resets of the password and of the account end
them all. The register ends its own and keeps a notice per member
(`sessions_ended_notice`, a migration that only creates it), told at
once and hourly until it confirms, as deletions are told: it names a
moment, so sessions made since stay, and the session that asked for a
change. A member answering one ends its sessions made before that
moment; a member signing someone in after a reset ends its own first
and makes the new session only once its clock is past the moment.
A reset not due says when it takes effect (`takesEffectAt` on
`PasswordRefusedException`), across members too.

The `simpleLogin` endpoint on halkyon_oidc's SimpleLogin preset: `begin`

most 30 an hour per network; `complete` with SimpleLogin's code, signed out
a session for the account with that SimpleLogin ID, signed in SimpleLogin
added to the caller's account, who becomes identified and anonymous no
longer. Someone new gets no account yet: their identity waits 30 minutes
under the attempt's ID (D16), with a handle suggested from their name,
`anna_mueller` (D17), for the sign-up of step 3.
The register alone holds the instance's SimpleLogin app
(`simpleLoginClientId`, `simpleLoginClientSecret`) and exchanges codes; a
member asks it for both steps and issues its own session. `SIGN_IN_WAYS`
says which ways the register offers, the instance's basics and the ways

hourly. No migration: the tables are halkyon_oidc's, already in place.

feat(base): SimpleLogin's forwarding page and Learn's App Links statement (ADR 0020, step 1)
SimpleLogin takes only https redirect addresses, each registered exactly,
so the instance's SimpleLogin app registers one page on the register's
web server, /simplelogin-callback, which sends the browser on to the app
that began the sign-in: a 303 to the desktop's loopback (127.0.0.1, a port
per app) or the phone's scheme, chosen by the marker the state begins with
(`<app>-<platform>.<rest>`, the rest 1 to 512 characters of base64url),
from a fixed table, so it sends nobody anywhere else. It forwards the code
or SimpleLogin's error (`deny`) with the state and nothing else, refuses
anything malformed, repeated or not a GET with a page that repeats nothing
it was given, and keeps and logs nothing (no-store, no referrer). It is
built ahead of the sign-in itself so development can sign in through
learn.halkyon.eu's page, which the development app registers too.
Android's assetlinks.json for Halkyon Learn signed with the release key
is answered by the Caddyfile on learn.halkyon.eu alone: the one domain the
project's builds name, and the server knows no app's key. A root test
holds its fingerprint to tool/release/android-certificate.sha256. The
app's intent filter comes with the sign-in; iOS's association waits for
an Apple team ID.
The profile page's language choice and look move to common/web_page.dart,
shared by both pages.

feat(crypto): TOTP and recovery codes
ADR 0017's second factor, in halkyon_base_server (base.dart):
- RFC 6238 with HMAC-SHA1, 6 digits, 30-second steps, one step either
way. checkTotp takes the account's last accepted step as a required
argument and refuses a code of that step or before, so no code is
accepted twice; every step of the window is computed and compared.
- 160-bit secrets in RFC 4648 Base32 (strict decoding); the otpauth
URI with issuer and account escaped.
- Ten recovery codes of eight Crockford characters (short_code.dart),
kept as SHA-256 hashes, each used once, every hash compared in
constant time.
- Tests: RFC 6238 Appendix B (8 digits, SHA-1, SHA-256, SHA-512), the
window, replay, RFC 4648's Base32 vectors, the recovery codes.
