 Bifrost's native Discord gateway is the conversation observer. A direct mention of the Bifrost bot, or a reply to one of its messages, becomes an immutable typed `bifrost.discord.persona_conversation_event.v0` only when the guild and channel have one exact Persona target binding. Bot-authored, ambient, empty, over-1200-character, unbound, and ambiguously bound messages do not enter the conversation path. The 1200-character cap is the shared signed alpha boundary with Epiphany. The observation store is Bifrost-private working state, never an actuator queue, and insert collisions must contain exactly equal content. VoidBot does not observe, schedule, or answer for the target Persona.
 
-Persona replies cross back through two explicit CultMesh surfaces. Epiphany is
-the sole writer of `epiphany.persona_discord_delivery_request.v0`; Bifrost
-reads that surface, authenticates the dedicated Persona-mouth signer, journals
-external execution before touching Discord, and is the sole writer of
-`bifrost.persona_discord_delivery_receipt.v0`. Epiphany reads receipts but
-never receives the Discord token or write access to Bifrost private state.
-`unknown` is terminal for automatic transport retry: an external post may have
-happened, so restart recovery must not manufacture a duplicate. Failed and
-unknown outcomes remain Persona pressure for explicit resolution.
+Persona speech goes out through Matrix, not Discord. `tools/persona-matrix-mouth.mjs` is the one process for every Persona (`PERSONAS`, a list of slugs): it holds each Persona's Matrix access token as its own systemd credential (`matrix-token-<persona>`) and nobody else holds any. Per Persona it keeps one `/sync` loop over the configured rooms and the account's direct rooms (a DM invitation from an account on `MATRIX_SERVER_NAME` is accepted while that Persona's brake is released, and one from any other server is declined), one cursor and one delivery sequence. A delivery carries the sender's Matrix id, the event's `m.mentions` user ids and whether the room is a DM. Reading wakes nothing and acks nothing: the heartbeat polls with the non-consuming `gamecult.persona.chat_pending_request.v1`, and only `chat_ack` advances a position. The mouth speaks on a `gamecult.persona.chat_send_request.v1` and joins rooms only while that Persona's brake (`/etc/gamecult/minds/<persona>/control.cc`) is released. One loopback CultNet RUDP endpoint serves all of them; a request naming an unlisted Persona gets a typed `chat_refusal` (`UnknownPersona`). Document shapes: `tools/persona-chat-documents.mjs`; golden bytes: `tests/fixtures/persona-chat-v1/`. The Discord posting actuator, its permit and its RUDP listener are removed.
 
 Bifrost admits an observation only when guild, channel, target runtime, canonical repository, Persona, producer, and producer runtime match a preconfigured `bifrost.persona_feedback.target_binding.v0` document in Bifrost's private provider store. That binding also owns source visibility, data classification, and the delivery-store target. Bifrost never infers public visibility from Discord identifiers. It classifies the author using its own `bifrost.discord.actor_link.v0` state: a match yields `linked_governance_feedback`; absence yields `unlinked_social_feedback`. Neither class grants adoption, work, release, or deployment authority.

+# Bifrost OIDC issuer
+
+Bifrost is the GameCult identity issuer. It runs an OpenID Connect provider on its public host so that Matrix
+Authentication Service (MAS) can sign chat users in with their Bifrost account. Heimdall authenticates people into
+Bifrost; it does not issue the identity chat sees.
+
+The provider is OpenIddict (`OpenIddict.AspNetCore` and `OpenIddict.EntityFrameworkCore`, 7.7.1). Bifrost owns two
+decisions at the authorize endpoint: who the chat user is, and whether they may get a session.
+
+## Endpoints
+
+The issuer is `Host:PublicBaseUrl`, normalized by .NET into an absolute URI. For a bare host that adds a trailing
+slash, so for `https://bifrost.gamecult.org` the issuer string is `https://bifrost.gamecult.org/`. Configure MAS with
+that exact string.
+
+| Endpoint | Path |
+| --- | --- |
+| Discovery | `/.well-known/openid-configuration` |
+| JWKS | `/.well-known/jwks` |
+| Authorization | `/connect/authorize` |
+| Token | `/connect/token` |
+| Userinfo | `/connect/userinfo` |
+
+Only the authorization code flow exists, and PKCE (S256) is required. There is no implicit, hybrid, password,
+client-credentials or device flow, no refresh token, and no dynamic client registration. The token endpoint takes
+`client_secret_basic` only. Scopes are `openid` and `profile`.
+
+## The one client
+
+Exactly one client is registered, from configuration, and seeded or updated at startup; every other application
+row (with its authorizations and tokens) is deleted at startup. Any other `client_id`, an unregistered `redirect_uri`, or a request without PKCE is refused by the
+provider before any sign-in redirect.
+
+## Configuration
+
+The section is `Bifrost:Oidc`. Absent, the provider surface is not mapped at all and discovery answers 404. Present,
+it must be complete: an unreadable or wrong-shaped file stops startup with a message that names the setting and never
+echoes its value.
+
+| Setting | Meaning |
+| --- | --- |
+| `Bifrost:Oidc:SigningKeyPath` | PEM file with an EC P-256 private key. Tokens and id_tokens are signed ES256; JWKS publishes exactly that key. A non-P-256 or public-only key stops startup. |
+| `Bifrost:Oidc:EncryptionKeyPath` | File holding 32 random bytes as base64 (`openssl rand -base64 32`). Encrypts the tokens OpenIddict issues, the access token and the parked authorize request among them. |
+| `Bifrost:Oidc:Clients:Mas:ClientId` | The client id MAS presents. |
+| `Bifrost:Oidc:Clients:Mas:ClientSecretPath` | File holding the client secret. |
+| `Bifrost:Oidc:Clients:Mas:RedirectUri` | MAS's callback URL, registered exactly. |
+| `Bifrost:Oidc:Clients:Mas:BackchannelLogoutUri` | Optional. MAS's back-channel logout URL, `https://<mas>/upstream/backchannel-logout/<provider ULID>`; absolute http(s) or startup fails. Unset: no logout is sent and no authorization is revoked. |
+
+There are no development or ephemeral keys in the host. Key files are provisioned like the other
+`[workload.secret_files]` paths.
+
+## Claims
+
+| Claim | Value |
+| --- | --- |
+| `sub` | `UserAccount.Id`, formatted `D` |
+| `preferred_username` | `NormalizedBifrostIdentity` (minted once; there is no rename path) |
+| `name` | `DisplayName`, else `BifrostIdentity` |
+
+No e-mail, no Heimdall id, no GitHub id, and no membership detail leaves Bifrost.
+
+## Who may sign in
+
+The authorize endpoint reads the cookie session and the same actor facts the `/App` policy reads.
+
+- No session: challenge to `/auth/sign-in`, which resumes the original request after sign-in. OpenIddict parks the
+  full request (its request token, in the OpenIddict token table, expiring after ten minutes, spent when used) and
+  the return path carries only a short `request_uri`, so `LocalReturnPath.MaxLength` stays 256.
+- Signed in, membership not `Active`: redirect to the client's `redirect_uri` with `error=access_denied` and
+  `error_description=The account is not an active GameCult member.`
+- Signed in, `Active`, but `NormalizedBifrostIdentity` empty: `error=access_denied` with
+  `error_description=The account has no Bifrost identity.`
+- Signed in and `Active`: a code is issued.
+- Token endpoint: membership is read again; an account no longer `Active` gets `invalid_grant` and no tokens.
+
+## Back-channel logout
+
+When `BackchannelLogoutUri` is set, a hosted reconciler (`OidcLogoutReconciler`) runs every 30 seconds. It lists the
+subjects holding valid authorizations of the MAS client; for each subject whose membership is not `Active` (the same
+reading the token and userinfo endpoints use; a deleted account or a subject that is not an account id counts as not
+`Active`) it POSTs one OIDC back-channel logout token to MAS, and only after a 2xx revokes that subject's authorizations,
+which also invalidates their tokens. Membership is never written by this path: any way of leaving `Active` (admin
+action, sync, a database edit, a future suspend) is covered because the work is derived from membership state.
+
+The token is an ES256 JWT signed with the issuer key, header `typ` `logout+jwt`, with `iss` as the id_token carries it,
+`aud` the MAS client id, `sub` the account id, `iat`, `exp` two minutes later, a fresh `jti` and the
+`http://schemas.openid.net/event/backchannel-logout` event. It carries no `nonce` and no `sid`; MAS finds the sessions
+by `sub`. It is sent as `application/x-www-form-urlencoded` field `logout_token` with a 10 second timeout, and the
+response body is never logged.
+
+Failure handling is per subject, in memory: a 5xx, a timeout or a network fault backs off exponentially from 30 seconds
+to 15 minutes; a 400 (token refused) or 404 (unknown provider ULID) is a configuration fault, logged by status only,
+and retried at the 15 minute cap. Nothing is revoked until MAS answers 2xx. A restart loses the backoff and nothing
+else: the authorizations table is the queue, so a later-set URI also catches up on earlier demotions.
+
+Tradeoff: delivery latency is up to one tick, and a member demoted and re-promoted inside one tick keeps their sessions.
+
+MAS verified at v1.28.0 (`crates/handlers/src/upstream_oauth2/backchannel_logout.rs`): the token is checked like an
+id_token (`iss`, `aud`, `alg`, JWKS signature), `exp` and `iat` are required, `sub` or `sid` is required, `nonce` must be
+absent. Owed on the MAS side (gamecult-chat): the provider's `backchannel_logout_uri` and
+`on_backchannel_logout: logout_all`. Re-check against the MAS version pinned there.
+
+## MAS configuration
+
+Configure MAS's upstream provider with the issuer above, the client id and secret, the token endpoint auth method
+`client_secret_basic`, the id_token signing algorithm `ES256`, scope `openid profile`, and a localpart claim import
+from `preferred_username`. MAS mints the Matrix localpart on first sign-in, so the claim must never change for an
+account.
+
+## Remaining scar
+
+Heimdall still mints its own account id in code (`src/app.ts` `createAccount`). That id is an authenticator handle
+and chat does not need it to move.

+# Eyes: estate internal tally, game-theory probes (2026-10-29)
+
+Fork: Fork Desk question 39, `eureka-body:question:estate-internal-tally` (InForce; options proportional | winner-take-all; Self's recommended: proportional). Context ruling `eureka-body:ruling:governance-estate-blocks`. Session self-2026-10-29-eureka. Facts and measured results only, no recommendation.
+Operator additions folded in (her words relayed by the Self): within-bloc vote-power curves ("Patrons vote power scales with donation total, but it's logarithmic... Member vote should scale with contribution... via a lower exponent"); present case ("I'm the only active member"); renormalization ruling ("normalize it by who actually voted").
+
+## Code, outputs, model
+Dir `sims/` (numpy 2.5.4, Python 3.13, `python -I <script>`; each `X.py` writes `X.out.md`, full tables there):
+`power.py` exact Banzhaf/Shapley and two-tier individual power; `mc.py` Monte Carlo outcomes; `weights.py` within-bloc curves; `growth.py` present case and growth path; `strat.py` misreport/abstention and logrolling; `noshow.py` no-show and quorum under renormalization; `lone.py` lone-estate bounds (her absent).
+- Pass rule as in Bifrost `MotionGovernanceService`: For/(For+Against) >= q, abstain excluded. Every tally renormalizes over estates with at least one For/Against ballot (the ruling); a WTA tie casts nothing, so a tied estate also drops out. Ties at exactly q pass (>=).
+- Sizes unless stated: Minds 8, Members 15, Users 30 voting (roll 300, 10% turnout), Patrons 4. Weight seeds M/Me/U/P: equal 25/25/25/25; minds-heavy 40/30/20/10; members-heavy 20/45/20/15.
+- "A priori" = Banzhaf coin-flip voters. "Motion model" (mc, weights W3): merit m~N(0,1), bloc taste e~N(0,1), bloc support p_b=logistic(1.7(0.6m+0.8e)); Minds intra-class correlation (ICC) via a shared beta-binomial propensity. ICC 0.44 is Kish-calibrated to Kohli 2026 (9 LLM judges ~ 2 effective votes, cited in the Bifrost prior-art note).
+- Assumptions, not data: Member contribution = operator holds share S (0.5/0.8/0.95) of the total, the rest a Pareto(1.16) quantile ladder; Patron donations [10, 50, 200, 5000].
+- Bug caught and fixed mid-run: the first mc.py drew per-voter propensities, which gives no correlation; results below are from the fixed shared-propensity version.
+
+## 1. Unitary blocs: a priori power (power.out.md)
+| weights | q | Banzhaf M/Me/U/P | Shapley M/Me/U/P | veto blocs |
+|---|---|---|---|---|
+| equal | .15/.5/.66 | .25 each | .25 each | none |
+| minds-heavy | .15 | .33/.33/.33/0 (Patrons dummy) | same | none |
+| minds-heavy | .5 | .42/.25/.25/.08 | .42/.25/.25/.08 | none |
+| minds-heavy | .66 | .50/.30/.10/.10 | .58/.25/.08/.08 | Minds |
+| members-heavy | .5 | .17/.50/.17/.17 | same | none |
+| members-heavy | .66 | .20/.40/.20/.20 | .17/.50/.17/.17 | Members |
+- Power is not weight: 40/30/20/10 at q=.5 gives Members and Users equal power; 10% Patrons are a dummy at q=.15.
+- Meta-vote on weights (the ruling votes on block sizes): a reallocation of weight is a divide-the-dollar game. A simple game's core is nonempty iff it has a veto player (standard; e.g. Osborne & Rubinstein 1994 ch. 13) [M]. With no veto bloc (most rows) every weight vector can be beaten by a winning coalition that moves weight to itself. Where a veto bloc exists (minds-heavy .66, members-heavy .66), that bloc must be in any reweighting coalition. At equal weights and q > .75 every bloc is a veto player.
+
+## 2. Individual power inside blocs, a priori (power.out.md)
+P(one voter flips the motion); sizes 8/15/30/4.
+| weights | q | rule | Mind | Member | User | Patron | max/min |
+|---|---|---|---|---|---|---|---|
+| equal | .5 | WTA | .118 | .096 | .064 | .158 | 2.5 |
+| equal | .5 | prop | .143 | .077 | .038 | .296 | 7.7 |
+| equal | .66 | WTA | .118 | .096 | .064 | .158 | 2.5 |
+| equal | .66 | prop | .026 | .015 | .007 | .047 | 6.5 |
+| minds-heavy | .5 | WTA | .169 | .108 | .051 | .061 | 3.3 |
+| minds-heavy | .5 | prop | .234 | .091 | .030 | .115 | 7.8 |
+| members-heavy | .5 | WTA | .037 | .189 | .016 | .058 | 11.5 |
+| members-heavy | .5 | prop | .125 | .151 | .033 | .189 | 5.8 |
+- Under prop each voter's marginal weight is w_b/n_b, so individual power scales ~1/n. Under WTA it scales ~1/sqrt(n) (Penrose). WTA compresses individual inequality, except where the council game makes a bloc near-dummy (members-heavy WTA: Users .016).
+- At q=.66 with coin-flip voters, prop individual power collapses (a bloc share rarely sits near the threshold). WTA is unchanged at equal weights (3 of 4 blocs either way).
+- Penrose sqrt shares for 8/15/30/4: 19.9/27.3/38.6/14.1. Using Minds n_eff 1.96 instead of 8: 11.0/30.4/43.0/15.7. Under sqrt weights the WTA individual powers are .093/.084/.096/.122, roughly equal (4 blocs is too few for exactness). Headcount weights make prop exactly equal (.106 each) but make WTA Minds and Patrons dummies (0) and Users a dictator.
+
+## 3. Monte Carlo, motion model (mc.out.md; Minds ICC .44)
+| weights | q | P(pass) prop | P(pass) WTA | P(outcomes differ) |
+|---|---|---|---|---|
+| equal | .15 / .5 / .66 | .934/.501/.265 | .838/.594/.404 | .098/.119/.148 |
+| minds-heavy | .15 / .5 / .66 | .913/.500/.299 | .796/.537/.357 | .122/.118/.091 |
+| members-heavy | .15 / .5 / .66 | .932/.500/.270 | .838/.500/.342 | .101/.111/.113 |
+- The two rules disagree on 9-15% of motions in every configuration. Prop is the weighted popular share, so each disagreement is a WTA referendum paradox (Nurmi 1998) [M]. WTA flattens the effective threshold: passes less at .15 and more at .66, because a bloc that clears its internal majority casts 100%.
+- Single-voter pivot (equal, q=.5), prop vs WTA: Mind .050/.021, Member .026/.023, User .013/.012, Patron .100/.076.
+- Minds correlation (equal, q=.5):
+
+| Minds ICC | n_eff of 8 | mean abs(Minds share - .5) | Mind pivot prop | Mind pivot WTA | P(Minds 4-4 tie) | P(rules differ) |
+|---|---|---|---|---|---|---|
+| 0 | 8.0 | .280 | .051 | .040 | .107 | .115 |
+| .44 | 1.96 | .379 | .050 | .020 | .054 | .119 |
+| .8 | 1.21 | .458 | .049 | .006 | .017 | .124 |
+| 1 | 1.0 | .500 | .047 | 0 | 0 | .126 |
+  Correlation pushes the Minds split toward 0/8 or 8/0, so prop and WTA deliver nearly the same Minds cast. Under WTA one Persona's flip almost never matters at ICC >= .44; under prop each Persona keeps a 1/8 slice regardless.
+- Users turnout (equal, q=.5): at turnout 1/3/10/30%, P(the WTA cast misstates the population majority) = .18/.12/.08/.04 and the mean prop share error = .19/.11/.06/.03. P(motion differs from the full-turnout result) is prop .077/.044/.024/.014 vs WTA .062/.040/.024/.014. The rules are about equal here.
+- Faction capture (Users population support .3, 9 random voters + k coordinated): P(WTA Users cast For) for k=0/3/6/9 = .10/.27/.80/.96; prop share .30/.48/.58/.65. Under WTA a 6-voter faction takes the whole Users weight 80% of the time; under prop it moves the share by .28.
+
+## 4. Within-bloc power curves (weights.out.md)
+Kish n_eff = (sum w)^2 / sum w^2. "Top" = the operator (Members) or the largest donor (Patrons). Internal Banzhaf = P(top's flip changes the bloc's WTA cast).
+| bloc | curve | S | n_eff | top share | top internal Banzhaf |
+|---|---|---|---|---|---|
+| Members 15 | one-each | - | 15.0 | .067 | .21 |
+| Members 15 | k=1 / 2 / 3 / 5 | .5 | 3.6 / 10.1 / 12.9 / 14.3 | .50 / .22 / .15 / .11 | 1.0 / .67 / .48 / .33 |
+| Members 15 | k=1 / 2 / 3 / 5 | .8 | 1.6 / 6.1 / 10.4 / 13.5 | .80 / .36 / .23 / .14 | 1.0 / .96 / .70 / .47 |
+| Patrons 4 | one-each / k=1 / log(1+d) | - | 4.0 / 1.1 / 3.3 | .25 / .95 / .42 | .75 / 1.0 / .75 |
+| Patrons 4 | k=3 / 5 / 10 | - | 2.4 / 3.2 / 3.8 | .59 / .45 / .35 | 1.0 / .75 / .75 |
+(The k=1, S=.5 row is an exact 50% tie with the rest, scored pivotal because tie-to-win counts as a change. Internal Banzhaf .75 for 4 one-each Patrons has the same cause.) On this donation ladder log(1+d) flattens like d^(1/5); d^(1/3) still leaves the top Patron dictating the bloc under WTA.
+Operator's whole-tally pivot (a priori, Patrons log(1+d); W2):
+| seed | q | S | one-each | k=1 | k=2 | k=3 | k=5 | (Mind / User, k=3) |
+|---|---|---|---|---|---|---|---|---|
+| equal | .5 | .5 prop/WTA | .069/.089 | .50/.42 | .23/.29 | .16/.20 | .12/.14 | .13/.11, .035/.059 |
+| equal | .5 | .8 prop/WTA | - | .75/.42 | .38/.40 | .24/.30 | .15/.20 | |
+| equal | .66 | .8 prop/WTA | - | .25/.42 | .09/.41 | .06/.30 | .04/.20 | |
+| members-heavy | .5 | .8 prop/WTA | .15/.18 | 1.0/.84 | .75/.81 | .50/.59 | .32/.40 | |
+- Under WTA her power is capped by the Members bloc's council power: about .42 at equal weights and .84 at members-heavy, reached once she dictates the bloc. Under prop it is uncapped at q=.5 (members-heavy k=1 S=.8: .999, which makes her near-dictator of the whole tally). At q=.66 prop shrinks every individual's power and WTA does not.
+- Exponent sensitivity, motion model (W3; equal, q=.5, S=.5, baseline Members k=3 and Patrons log): P(outcome changes vs baseline) for Members one-each/k=1/k=2/k=5 is prop .014/.051/.010/.007, WTA .014/.061/.012/.008. For the Patron curve one-each/k=1/k=3/k=5/k=10 it is prop .027/.080/.026/.006/.013, WTA .032/.033/.033/0/0. Outcomes move by 1-8%. Her pivot moves more: .025 (one-each) to .21 (k=1) prop, and .022 to .30 WTA.
+
+## 5. Present case and growth (growth.out.md, noshow.out.md; renormalized)
+Present case: Members = her alone, Minds 8, Users and Patrons empty, so only two estates are live and their weights renormalize. P(pass | she votes For / Against / stays home), Minds coin-flip (N2):
+| seed (M,Me) | q | prop | WTA |
+|---|---|---|---|
+| 25,25 | .5 | 1.00 / .004 / .64 | 1.00 / .36 / .36 |
+| 25,25 | .66 | .86 / 0 / .15 | .64 / 0 / .36 |
+| 40,30 | .5 | .996 / .035 / .64 | .64 / .36 / .36 |
+| 20,45 | any | 1.00 / 0 / home .64 (.5), .15 (.66) | 1.00 / 0 / .36 |
+- Equal seed, q=.5: under prop she decides the motion 99.6% of the time (Minds share must hit 8/0 to beat her Against). Under WTA her Against is overridden whenever the Minds majority is For (25 vs 25 ties and passes at >=). Minds-heavy WTA: a unanimous Minds bloc decides alone (her pivot 0.000 with correlated Minds). Members-heavy: she is dictator under both rules.
+- With 3 Users + 1 Patron present (G1), equal q=.5: her pivot is .50 prop / .41 WTA.
+When her single vote stops deciding the Members bloc under WTA (share <= .5; G2):
+| curve | S=.5 | S=.8 | S=.95 |
+|---|---|---|---|
+| one-each | n=2 (tie), n>=3 | n=2 (tie), n>=3 | n=2 (tie), n>=3 |
+| k=5 | n>=2 (tie at 2) | n=3 | n=5 |
+| k=3 | n>=2 | n=5 (n=3 at .501) | n=10 |
+| k=2 | n>=2 | n=10 | n=50 |
+| k=1 | always tied at .5 | never | never |
+Growth path, her whole-tally pivot (equal seed, q=.5, Users 10, Patrons 2): alone .72 prop / .43 WTA. n=5, S=.8: k=1 .60/.43, k=3 .31/.38, k=5 .24/.22, one-each .15/.16. n=20, S=.8: k=3 .16/.29, k=5 .10/.18, one-each .04/.08. Members-heavy seed, n=20, S=.8, k=3: .38/.59.
+
+## 5b. Lone estate bounds, she absent (lone.out.md)
+Operator ruling relayed: "But they totally should be able to make decisions without me if I'm not there to vote". Under renormalization the Minds estate is then the whole tally.
+- Quorum floors a lone, fully turned-out Minds estate meets:
+  - Headcount floor: 8/9 = .889 of eligible individuals.
+  - Estate-weight floor (Minds weight over live-eligible estate weight): .500 equal, .571 minds-heavy, .308 members-heavy.
+  - Any floor above these values requires her turnout. The at-least-two-estates floor (section 6 N1) requires her by construction while Users and Patrons are empty, so it is kept only as a later-membership comparison.
+- Category thresholds (Bifrost `MotionCategoryPolicy`), lone Minds, all 8 voting. Columns: Personas needed under prop, then P(pass) in the motion model at Minds ICC 0 / .44 / 1:
+  - Bugs .15: 2 needed; .78/.65/.50
+  - Cosmetics .30: 3 needed; .66/.59/.50
+  - Balance .40: 4 needed; .55/.53/.50
+  - Features and NewContent .50: 4 needed; .55/.53/.50
+  - FundamentalDesign .66: 6 needed; .34/.42/.50
+  - Under WTA a lone estate casts 100% For or 100% Against, so the ratio is 1 or 0 and every category passes on a 5-of-8 majority: .45/.47/.50. Category thresholds are inert for a lone estate under WTA and binding under prop.
+  - At ICC 1 (one effective Mind) both rules give .50 at every threshold: the threshold stops discriminating when the estate votes as one.
+- Delay-plus-cancel window: P(she is back before effect), absence ~ Exponential(mean A); this measures the chance a cancel opportunity exists, not that it is used.
+
+  | delay D | A=1 day | A=3 days | A=7 days | A=14 days |
+  |---|---|---|---|---|
+  | 1 day | .63 | .28 | .13 | .07 |
+  | 3 days | .95 | .63 | .35 | .19 |
+  | 7 days | 1.00 | .90 | .63 | .39 |
+  | 14 days | 1.00 | .99 | .86 | .63 |
+
+  Prior-art delays (Bifrost prior-art note, section 5 and section 1):
+  - Compound Timelock: 2 days.
+  - OpenZeppelin Timelock: exists so users can "exit the system if they disagree" before a decision executes; a canceller role; a guardian may cancel at any stage.
+  - Olympus Bravo: veto guardian until execution.
+  - Apache: votes run at least 72 h.
+  - Rust FCP: 10 days, and a raised concern blocks.
+  - Beanstalk had no delay; its governance attack drained ~$76M.
+
+## 6. Strategic probes
+S1 (strat.py, exhaustive; sizes 3/3/2/2, sincere profiles, no quorum): 0 profitable misreports or abstentions under either rule at any q or seed. The For/(For+Against) ratio is monotone and participation-safe without a quorum. With a cast-weight quorum (>= 50% of estate weight), WTA produced 144-288 profitable abstentions per 10240 cases: an abstention creates an internal tie, the estate drops out, and quorum fails. Prop produced 0.
+N1 (noshow.py, renormalized, quorum floors). Columns: individual profitable deviations / hers / profitable estate stay-home. Present case 8/1/0/0, 512 profiles:
+- No quorum: 0 / 0 / 0 in every seed, q and rule.
+- Headcount quorum (>= half of eligible): 0 individual deviations. Estate stay-home is profitable in 56-93 profiles, because with only 9 eligible the Minds estate staying home breaks quorum.
+- "At least two estates": WTA equal q=.5 gives 93 / 93 / 186; prop gives 1 / 1 / 94. Her staying home kills any motion she opposes, because with Users and Patrons empty she is the second estate. Minds-heavy q=.5: prop 9 / 9 / 101, WTA 93 / 93 / 93. At q=.66 most of these drop to 0 (prop equal still 56 estate cases).
+- Mixed 3/1/2/1 with everyone voting: 0 under every floor. The no-show leverage comes from empty estates, not from the rule itself.
+S2 logrolling (6-motion agendas, 1500 each, greedy mutually profitable pairwise trades; welfare = sum of bloc utilities). Unitary blocs can deliver their whole weight; proportional blocs' leadership moves the share by delta:
+| seed | bloc type | P(>=1 trade) | mean trades | mean welfare change | P(welfare falls) | P(a non-trader loses) | P(a trader ends worse) |
+|---|---|---|---|---|---|---|---|
+| equal | unitary | .615 | 1.04 | +.168 | .245 | .397 | .234 |
+| equal | prop delta .5 | .430 | .66 | -.396 | .338 | .305 | .127 |
+| equal | prop delta .2 | .127 | .17 | -.027 | .071 | .093 | .017 |
+| minds-heavy | unitary | .615 | .90 | +.016 | .302 | .484 | .184 |
+| minds-heavy | prop delta .5 | .324 | .44 | -.306 | .230 | .261 | .076 |
+- Unitary blocs find trades on most agendas. Trades raise mean welfare (equal seed) but impose losses on a non-trading bloc in 40-48% of agendas and leave a trader worse than sincere in 18-23%, which is Riker & Brams's paradox of vote trading at bloc scale. Partial-delivery blocs trade far less. The negative mean welfare at delta .5 is a model result (proportional shares near .5 flip low-stakes motions) that I have not cross-checked.
+
+## 7. Literature (one or two lines each; [V] = verified by search this pass, [M] = from memory, not fetched)
+- Putnam 1988, "Diplomacy and Domestic Politics: The Logic of Two-Level Games", Int. Org. 42(3):427-460 [M]. A deal must lie in each side's domestic win-set; a smaller win-set gives bargaining advantage (the Schelling conjecture), with the risk of involuntary defection. Mapping: a bloc parliament that ratifies the bloc position is a level-II ratifier. A prop bloc has no ratified position to bargain from.
+- Schelling 1956 "An Essay on Bargaining", AER 46(3); Strategy of Conflict 1960 [M]. Binding oneself (burning bridges) is power. A unitary bloc whose position is fixed by an internal vote is a visible commitment device; prop splitting commits nothing beyond the count.
+- Tests of the conjecture [V]. Mo 1995 APSR 89(4):914-924: a negotiator may gain by giving an agent veto, but only when the agent's preferences are extreme enough and depending on what the other side knows. Iida 1993 JCR and 1996 Public Choice: incomplete information about domestic preferences drives ratification failure; two-sided constraints give relatively equitable outcomes. Tarar 2001 JCR 45(3):320-340: with both sides constrained and incomplete information, the opposite of the conjecture can occur. All four estates having parliaments is the two-sided case.
+- Diermeier & Feddersen 1998 APSR 92(3) [M]: the vote-of-confidence procedure makes coalitions cohesive, and cohesion raises a coalition's value in legislative bargaining. This is the party-discipline analogue: a disciplined unit outbargains an undisciplined one. Krehbiel 1993 "Where's the Party?" and Cox & McCubbins 1993 dispute how much discipline is real.
+- Riker & Brams 1973 "The Paradox of Vote Trading", APSR 67(4) [M]: individually rational trades can leave all parties worse off. S2 measures it.
+- Snyder, Ting & Ansolabehere 2005 "Legislative Bargaining under Weighted Voting", AER 95(4) [M]: in Baron-Ferejohn bargaining, expected payoffs track minimal-integer-representation weights rather than Banzhaf/Shapley. This applies to the weight meta-vote as distributive bargaining among unitary blocs.
+- Penrose 1946 JRSS 109; Banzhaf 1965 Rutgers L. Rev. 19 [M]. Two-tier WTA equalizes individual power with sqrt(n) weights. Banzhaf 1968 "One Man, 3.312 Votes" showed large US states' unit rule over-empowers their voters [M].
+- Jagiellonian compromise [V]: Słomczyński & Życzkowski; sqrt-of-population weights with quota ~62% (61.5% for EU-27) (arXiv cond-mat/0405396, 0712.2699). Poland tabled it in 2007; the Council adopted the double majority instead.
+- Gelman, Katz & Bafumi 2004, BJPS 34(4):657-674 [V]: the coin-flip model overstates decisiveness in large units; empirically, proportional weights are "basically fair" and sqrt is not. Kirsch 2007 (Homo Oeconomicus) [M]: with correlated voters the optimal two-tier weights move from sqrt(n) toward n. The Minds correlation table above is a local instance: a high-ICC bloc of 8 has n_eff ~ 2.
+- Coleman 1971 [M]: separates the power to initiate action from the power to prevent it. The thresholds .15 vs .66 shift power between these two, which is visible in the q rows of section 2.
+- Electoral college unit rule [M]. Pathologies: campaigning and policy concentrate in swing states (Strömberg 2008 AER 98(3)); referendum paradox (Nurmi 1998 SCW 15). Faithless electors are bound by state law (Chiafalo v. Washington, 2020); in a bloc parliament the analogue is a Persona breaking the bloc mandate.
+- Estates-General 1789 [M]: vote by order (each estate one unitary vote) vs by head; the Third Estate refused the unitary-order rule and declared itself the National Assembly on 17 June 1789. Precedent: a unitary-estate rule is contested when one estate's size outgrows its weight.
+- Lijphart 1969 World Politics 21(2); Democracy in Plural Societies 1977 [M]. Consociationalism has four pillars: grand coalition, segmental autonomy, proportionality and mutual veto. Segmental autonomy fits each estate running its own internal process; mutual veto corresponds to the q > .75 equal-weight case in section 1.
+- Hirschman 1970 [M]: exit, voice, loyalty. In section 5 no-show acts as exit-as-leverage when an estate is the quorum's second member.
+
+## 8. Candidate articulations of the hunch: what the evidence shows
+- Credible commitment / paradox of weakness. Supported in theory by Putnam, Schelling, Mo and Diermeier-Feddersen; qualified by Mo (needs an extreme agent) and reversed under two-sided incomplete information (Tarar). In sim, only unitary blocs can deliver whole-weight trades (S2: 61.5% of agendas vs 12.7% at delta .2).
+- Power games in the open. Supported in structure: unitary blocs have 2^4 = 16 coalitions and the trades are pairwise and nameable. Under prop, influence travels through individual cross-bloc switching (prop pivots are per-individual, section 2). Contradicted in part by S2: open bloc trades still harm a non-trading bloc in 40-48% of agendas (Riker-Brams).
+- Internal deliberation absorbs correlated noise. For Minds at ICC >= .44, prop and WTA already cast nearly the same weight (section 3), so the internal rule matters little there; a parliament would decide which Persona's argument wins, not the tally. For Users at low turnout, both rules carry the same sampling error (.08 at 10%), and WTA is more capturable by a small faction (k=6: 80%).
+- Legibility of who owes whom. Unitary trades are pairwise records; under prop the "debt" is spread over individuals. No source measured this directly. Not found.
+- Individual equality cuts the other way. WTA two-tier is Penrose-equalizable with sqrt weights; prop needs headcount weights. Gelman et al. and Kirsch argue that correlation pulls the fair weights back toward proportional.
+- Operator dominance. Under WTA her ceiling is the Members bloc's council power (.42 equal, .84 members-heavy). Under prop at q=.5 her influence has no such ceiling. Her internal dictatorship of Members ends at the n shown in the section 5 table.
+- Renormalization with no quorum: participation-safe in every exhaustive probe. Adding any quorum floor while estates are empty hands the sole Member, or the Minds estate, a stay-home veto. The two-estates floor conflicts with the "decide without me" ruling today. The bounds that remain on a lone Minds estate are a headcount floor <= .889, category thresholds (binding only under prop, and void at ICC 1), and a delay window whose cancel opportunity depends on her absence length (section 5b).
+
+## 9. Third rule: `bloc-parliament-at-threshold` (bpt)
+Each live bloc casts its whole weight For iff its internal For share (abstain excluded) >= the category threshold q, else Against. The council then needs weighted For >= q over live estates (renormalized). Code `estate-sims\third.py` (out `third.out.md`) and `estate-sims\bounds.py` (out `bounds.out.md`). The model and draws are the same as sections 3-6 (Minds ICC .44, sizes 8/15/30/4).
+- **bpt vs WTA at q=.5:** these differ only at exact internal ties. A 4/8 Minds split casts For under bpt (.5 >= .5) and nothing under WTA. With continuous shares (logrolling) the two are identical.
+
+**Aggregate bounds** (all four estates live; lowest weighted popular For share that can pass / highest that can fail; prop is exactly q / just under q). bpt applies q twice, so it widens the band on both sides:
+| seed | q | WTA | bpt |
+|---|---|---|---|
+| equal | .15 | .125 / .500 | .037 / .150 |
+| equal | .5 | .250 / .625 | .250 / .625 |
+| equal | .66 | .375 / .750 | .495 / .830 |
+| minds-heavy | .66 | .350 / .800 | .462 / .864 |
+| members-heavy | .66 | .400 / .825 | .528 / .881 |
+- Equal seed, q=.15: one bloc with 15% internal For passes the motion, so 3.7% weighted support suffices.
+- Equal seed, q=.66: three blocs at 66% pass with 49.5% support, while four blocs at 65.9% fail with 65.9% support.
+
+**Outcomes** (T1): P(pass) prop / WTA / bpt, then P(outcomes differ) bpt-prop / bpt-WTA / prop-WTA:
+| seed | q | P(pass) | differ |
+|---|---|---|---|
+| equal | .15 | .934 / .838 / .985 | .050 / .147 / .098 |
+| equal | .5 | .502 / .594 / .676 | .179 / .082 / .119 |
+| equal | .66 | .265 / .405 / .233 | .080 / .171 / .148 |
+| minds-heavy | .5 | .502 / .537 / .575 | .126 / .038 / .117 |
+| members-heavy | .66 | .271 / .343 / .194 | .099 / .149 / .113 |
+- bpt is the most permissive rule at .15 and the strictest at .66. At .5 it passes more than WTA because internal ties count For.
+
+**Pivots and correlation** (T2, T3; equal seed):
+- Single-voter pivot M/Me/U/P under bpt:
+  - q=.15: .002/.004/.002/.017
+  - q=.5: .018/.019/.010/.082
+  - q=.66: .018/.018/.010/.068
+- For comparison at q=.5: prop .050/.026/.014/.102; WTA .020/.023/.011/.076.
+- Single-Persona pivot by Minds ICC 0 / .44 / .8 / 1:
+
+  | q | prop | WTA | bpt |
+  |---|---|---|---|
+  | .15 | .020 / .020 / .021 / .021 | .024 / .014 / .004 / 0 | .006 / .002 / .001 / 0 |
+  | .5 | .051 / .050 / .050 / .048 | .040 / .021 / .007 / 0 | .038 / .018 / .006 / 0 |
+  | .66 | .044 / .042 / .040 / .040 | .040 / .020 / .007 / 0 | .036 / .017 / .006 / 0 |
+
+  Under bpt, as under WTA, a correlated Minds bloc leaves one Persona almost no pivot; prop keeps a 1/8 slice at every correlation.
+
+**Users faction capture** (T4; Users population support .3, 9 random voters + k coordinated For). P(Users bloc casts For):
+| k (share of voters) | WTA | bpt .15 | bpt .5 | bpt .66 | prop share |
+|---|---|---|---|---|---|
+| 0 (0) | .10 | .80 | .10 | .03 | .30 |
+| 1 (.10) | .10 | .96 | .27 | .03 | .37 |
+| 2 (.18) | .27 | 1.00 | .27 | .03 | .43 |
+| 3 (.25) | .27 | 1.00 | .54 | .10 | .48 |
+| 6 (.40) | .81 | 1.00 | .81 | .27 | .58 |
+| 9 (.50) | .96 | 1.00 | 1.00 | .54 | .65 |
+| 12 (.57) | 1.00 | 1.00 | 1.00 | .80 | .70 |
+- At q=.15 the bloc casts For with no faction at all 80% of the time (population support .3 > .15); a 2-voter faction (18%) makes it certain. This confirms the coordinator's note: at .15, about a 15% faction captures the bloc's whole weight.
+- At .66 a faction needs roughly half the turnout to capture the bloc half the time.
+
+**Logrolling** (T5; 800 agendas, 6 motions):
+| seed | q | rule | P(>=1 trade) | mean welfare change | P(a non-trader loses) | P(a trader ends worse) |
+|---|---|---|---|---|---|---|
+| equal | .15 | WTA / bpt / prop .5 | .128 / .001 / .007 | +.56 / +.01 / +.05 | 0 / 0 / 0 | .007 / 0 / 0 |
+| equal | .5 | WTA = bpt / prop .5 | .589 / .451 | +.14 / -.43 | .376 / .316 | .231 / .146 |
+| equal | .66 | WTA / bpt / prop .5 | .614 / .367 / .245 | +.10 / +.60 / +.41 | .393 / .250 / .177 | .231 / .071 / .035 |
+| minds-heavy | .5 | WTA = bpt / prop .5 | .608 / .330 | -.05 / -.26 | .490 / .282 | .176 / .071 |
+| minds-heavy | .66 | WTA / bpt / prop .5 | .463 / .362 / .282 | +.17 / +.39 / +.37 | .375 / .289 / .206 | .095 / .031 / .043 |
+- At .15, almost nothing is left to trade under bpt: nearly everything passes.
+- At .66, bpt trades less than WTA, with higher mean welfare and less third-party harm. Most remaining trades build supermajorities for motions that a strongly-wanting minority of blocs care about.
+
+**Lone Minds, she absent** (T6). P(pass) at Minds ICC 0 / .44 / 1:
+| category | q | prop = bpt | WTA |
+|---|---|---|---|
+| Bugs | .15 | .77 / .65 / .50 | .45 / .47 / .50 |
+| Cosmetics | .30 | .66 / .59 / .50 | .45 / .47 / .50 |
+| Balance | .40 | .56 / .53 / .50 | .45 / .47 / .50 |
+| Features / NewContent | .50 | .56 / .53 / .50 | .45 / .47 / .50 |
+| FundamentalDesign | .66 | .34 / .42 / .50 | .45 / .47 / .50 |
+- A lone estate under bpt behaves exactly as under prop: the internal threshold is the binding one, so categories bind. Under WTA they are inert.
+
+**Present case** (T7; Minds 8 coin-flip, her alone, Users/Patrons empty). P(pass | she For / Against / home):
+| seed | q | prop | WTA | bpt |
+|---|---|---|---|---|
+| equal | .15 | 1 / .855 / .965 | 1 / .363 / .363 | 1 / .965 / .965 |
+| equal | .5 | 1 / .004 / .637 | 1 / .363 / .363 | 1 / .637 / .637 |
+| equal | .66 | .855 / 0 / .145 | .637 / 0 / .363 | .145 / 0 / .145 |
+| minds-heavy | .5 | .996 / .035 / .637 | .637 / .363 / .363 | .637 / .637 / .637 |
+| members-heavy | any | For always passes, Against always fails, under all three rules | | |
+- Under bpt with two equal live estates:
+  - At q <= .5 her For forces passage, and her Against has the same effect as staying home.
+  - At q=.66 her Against is a veto, and her For has the same effect as staying home.
+- Minds-heavy q=.5 under bpt: her vote is irrelevant (.637 in every column), and the Minds alone decide.
+
+**Operator's whole-tally pivot** (T8; coin voters, Users 10, Patrons 2 on log(1+d), her share of contribution S=.8). Values are prop / WTA / bpt:

+- At .15 under bpt, the coin-flip blocs almost always clear 15%, so no single voter matters, her included.
+- At .66, bpt gives her the smallest pivot of the three rules at every Members size, because she can block her bloc but rarely flips the council.
+
+**Strategic checks** (T9; exhaustive, renormalized, no quorum; sizes 8/1/0/0 and 3/3/2/2, all seeds and q): 0 profitable misreports, 0 profitable abstentions and 0 profitable estate stay-homes. bpt is monotone and participation-safe here, as prop and WTA were in sections 6 and N1.
+
+## 10. Capping the operator: weight share vs decisiveness
+Her words, relayed: "I would limit my influence by half, just so I'm not deciding everything". Code `estate-sims\cap.py` (out `cap.out.md`, full grid: 3 cases x 3 seeds x 3 q x 5 caps x 3 rules).
+- **Weight share x:** her internal share of Members x Members weight / live weight (renormalized).
+- **How the cap c works:** if she is the sole Member, the Members estate weight is cut to c/(1-c) x the other live weight. Otherwise her internal weight is cut until x = c.
+- **Decisiveness:** her pivot rate, measured twice. Coin voters (Banzhaf) and the motion model (Minds ICC .44) give different numbers for the same rule.
+- **Unilateral pass (U+):** her For passes with everyone else Against.
+- **Unilateral block (U-):** her Against fails with everyone else For.
+- Ties pass (>=).
+
+**Present case** (Minds 8, her alone, two live estates). Cells: pivot coin / pivot motion, with U+U- flags:
+| seed, q | cap (x) | prop | WTA | bpt |
+|---|---|---|---|---|
+| equal .15 | none = .5 (.50) | .14 / .42 YN | .64 / .53 YN | .03 / .35 YN |
+| equal .15 | .33 | .03 / .35 YN | .64 / .53 YN | .03 / .35 YN |
+| equal .5 | none = .5 (.50) | .996 / .73 YN | .64 / .53 YN | .36 / .47 YN |
+| equal .5 | .49 | .992 / .46 NN | .27 / .06 NN | 0 / 0 NN |
+| equal .5 | .33 | .71 / .17 NN | .27 / .06 NN | 0 / 0 NN |
+| equal .66 | none / .49 / .40 | .86 / .58 to .64 / .53 NY | .64 / .53 NY | .14 / .42 NY |
+| equal .66 | .33 | .64 / .25 NN | .27 / .06 NN | 0 / 0 NN |
+| members-heavy .5 | none (.69) | 1 / 1 YY | 1 / 1 YY | 1 / 1 YY |
+| members-heavy .5 | .5 / .49 | same as equal .5 at cap .5 / .49 | | |
+- **A 50% cap with ties passing does not take away her unilateral power.**
+  - In the two-estate case: at q <= .5 her For alone passes; at q > .5 her Against alone blocks.
+  - Generally: U+ holds iff x >= q, and U- holds iff x > 1-q. Removing both needs x < min(q, 1-q):
+    - q=.5: any cap below .5 (.49 works).
+    - q=.66: below .34 (.40 and .49 still leave her the block).
+    - q=.15: below .15 (no tested cap removes U+).
+- **Pivot at or below half, present case:**
+  - With cap .49 at q=.5: WTA .27 and bpt 0 on both measures (under bpt the Minds then decide alone).
+  - Prop stays at .99 on coin voters even at cap .49 (and .71 at .33). The motion model gives prop .46 at cap .49 and .17 at .33. One Persona For is enough to carry her 49% For past .5, and she loses only to a unanimous Against from the Minds.
+  - WTA at .15 stays at .64 / .53 under every cap. At .15, x >= .15 keeps U+, and the Minds estate casts all or nothing.
+
+**Growth path** (S=.8, k=3, Users 10, Patrons 2). Her weight share is already below every tested cap, so no cap binds:
+- x = .10 / .12 / .18 at n=5 for equal / minds-heavy / members-heavy.
+- x = .05 / .06 / .09 at n=20.
+
+Her decisiveness still exceeds half in some cells (coin / motion):
+| case | prop | WTA | bpt |
+|---|---|---|---|
+| n=5, members-heavy, q=.5 (x=.18) | .61 / .31 | .76 / .42 | .64 / .39 |
+| n=5, equal, q=.5 (x=.10) | .31 / .15 | .38 / .21 | .26 / .19 |
+| n=20, members-heavy, q=.5 (x=.09) | .38 / .14 | .59 / .15 | .50 / .15 |
+| n=5, members-heavy, q=.66 | .24 / .26 | .55 / .32 | .06 / .24 (U- under bpt) |
+- Under WTA and bpt, her pivot comes from steering a bloc that carries 45% of the weight, not from her own 9-18% share. A cap on her personal weight share therefore leaves this channel open.
+- Under bpt at .66 she gets a unilateral block at n=5 members-heavy with x=.18: her Against holds the Members internal For share under .66, so the whole 45% is cast Against.
+
+**Distinction, as measured:**
+- **Weight share is a rule parameter.** A cap on it is enforceable per tally (renormalized) and removes U+/U- only when x < min(q, 1-q) of the tally.
+- **Decisiveness (pivot rate) is not a rule parameter.** It is a function of the rule, the threshold, the bloc structure and how everyone else votes. The same cap gives .99 or .46 (prop, q=.5, cap .49) depending on the voter model. No weight cap tested bounds it under every model.
+- Holding her decisiveness at or below half under unitary rules (WTA, bpt) would need a cap on the weight of any bloc she can steer, or on her internal decisiveness in that bloc. A cap on her own share does not do it.
+- Present case, equal seed: rule and cap combinations whose pivot is at or below .5 on both voter models.
+  - q=.15: prop at every cap (.14 / .42 uncapped); bpt at every cap (.03 / .35). WTA at no cap (.64 / .53).
+  - q=.5: WTA and bpt at cap .49 or lower. Prop at no tested cap (coin .71 even at .33).
+  - q=.66: bpt at every cap (.14 / .42), but U- survives until the cap is below .34. WTA at cap .33. Prop at no tested cap (coin .64 at .33).

+Cap c on her WEIGHT SHARE of the renormalized tally: her share = (her internal share of Members) * W_Me / W_live.
+If she is the sole Member, the cap shrinks the Members estate weight to c/(1-c) * (other live weight);
+otherwise it shrinks her internal weight until her share = c. Then measure DECISIVENESS:

+# Swarm governance on Bifrost: readiness and prior art (2026-10-29)
+
+Serves follow-up `eureka-body:follow_up:swarm-governance-on-bifrost` and ruling `eureka-body:ruling:self-run-result-to-classifier` (classifier tuning by swarm vote). Two Eyes passes, facts only. Part 1 reads Bifrost at 7b63031; part 2 is prior art from the web, with confidence tags.
+
+## Part 1: Bifrost governance readiness
+
+Motions (Postgres/EF, Razor + Eve surface): Domain/BifrostModels.cs:665-721 (Motion, Vote), enums :86-115; Features/Motions/MotionGovernanceService.cs (create :13, vote :47, close :95-131); MotionCategoryPolicy.cs thresholds Bugs .15, Cosmetics .30, Balance .40, Features .50, NewContent .50, FundamentalDesign .66.
+Pass rule: For weight / (For+Against weight) >= ApprovalThreshold; Abstain excluded; no quorum field or code anywhere (grep "quorum" empty). Close is manual by creator or CanModerateMotions (:105); ResolveStatusLabel also derives Passed/Failed display after ClosesAtUtc.
+Weight: Membership.EffectiveVotingWeight = 0 unless Status Active, else max(1, sum current TierSnapshot weights) (BifrostModels.cs:357-361). TierSnapshotKind Patron|Contributor.
+Membership: MembershipStatus Authenticated|PendingApproval|Active|Suspended; MemberRole StandardMember|Producer|Maintainer|LedgerReviewer|PlatformAdmin (RoleAssignment); flags IsPlatformAdmin, CanManageProjects, CanManageLedger, CanModerateMotions. Activation: bootstrap admin, admin approval (Pages/App/Members), Heimdall member claim. Native registration POST /auth/bifrost/register is anonymous, yields Authenticated only. /App is ActiveMember-gated (Program.cs:57).
+Personas: no Persona account/voter class. BridgeActorKind Member|Agent|Persona|Service exists for bridge actions only (BifrostModels.cs:178). A Persona can only vote if it holds a UserAccount with Active membership (nothing in code makes one). Persona identity names are "reserved in Bifrost's identity namespace" per gamecult-ops/docs/gamecult-chat-target.md:84,179: Persona Matrix user "Registered by the mouth when Bifrost governance approves the Persona" -- documented; no code for that approval found.
+Typed-document exposure: motions/votes are Postgres rows, not CultCache docs. GET /eve/governance/surface (Program.cs:513, ActiveMember-gated) returns Eve JSON surface (Eve is deprecated per F:\Projects\CLAUDE.md). MotionEveSurfaceService names cultmesh://asgard.starfire.bifrost/commands/motion and motion.create/vote/close commands; no handler for that route found in code (grep). verse-service-contract.md:60,185-196 documents schema gamecult.bifrost.governance and the command route; schema ids for motion/vote listed as todo (:256).
+Governance topics/comments: tools/governance-threads.mjs, CultCache file .bifrost/governance-threads.cc, types bifrost.governance.topic / topic-comment; statuses open->consensus_ready->approved->dispatched->closed; support/objection are comment stances, not votes; the web app never reads it (docs/concept-mill-votes-target.md facts 1-5). Eyes pass 2026-10-10 found no such store on Yggdrasil. Web keeps only GovernanceActivityReceipt rows.
+Concept Mill votes (the one different vote system): ConceptVoteModels.cs, Features/ConceptVotes/*, Pages/Mill/Vote; VoterClass Anonymous|Account|Member; public tally export /public/concepts with CORS (ConceptTallyExport.cs). Per-subject appraisals, not motions; deployed in 67072b2 lineage.
+Chat integration: persona-matrix-mouth.mjs (Persona Matrix speech, main 7b63031), OIDC issuer + back-channel logout on membership leave (main 1894f65); persona feedback ingress/delivery as signed CultCache docs (docs/bridge.md:195-217). No motion/vote surface in chat found. Discord/Reddit voting prompts documented as future (full-implementation-strategy.md:78-79).
+UI: Razor /App/Motions (Pages/App/Motions/Index.cshtml[.cs]), /App/Members; no tally history page beyond list.
+Docs: docs/verse-service-contract.md, full-implementation-strategy.md (Phase 3 governance and revenue share), bridge.md, agent-transport.md, concept-mill-votes-target.md, jurisdiction-map.md.
+Ruling read: eureka-body:ruling:self-run-result-to-classifier (InForce, Operator, 2026-10-29): "tuning authority belongs to a swarm decision process, pending that process existing."
+Not read: Bifrost tests, jurisdiction-map.md, live DB contents (motion count unknown), campaign rulings beyond the one above.
+
+## Part 2: Prior art
+
+## 1. Quorum and close timing
+
+Apache (https://www.apache.org/foundation/voting.html) [P]
+- Votes should generally run at least 72 hours so all time zones can take part.
+- Lazy consensus = silence gives assent; not usable for code changes under review-then-commit unless declared at vote start.
+- Types: procedural = simple majority (more +1 than -1); code modification = consensus approval (3 +1, no -1) unless lazy consensus declared; release = majority approval (3 binding +1, more +1 than -1).
+- Veto only on code modifications: a -1 needs technical justification, else invalid; it blocks until withdrawn. Releases cannot be vetoed.
+- Binding votes: PMC members; others advisory. Only explicit votes count.
+- Page does not define "lazy majority" or "2/3 majority" (those terms are in other ASF docs, not checked).
+
+IETF rough consensus, RFC 7282 (https://www.rfc-editor.org/rfc/rfc7282.html) [P]
+- Explicitly not voting; the chair judges whether every technical objection was considered and answered; call is appealable.
+- Named failure modes: capitulation (objector gives up unanswered), horse-trading, vote stuffing (recruiting voices to swamp objections), polls treated as decisions, ignored objections.
+
+Loomio (https://www.loomio.com/docs/en/user_manual/polls/vote_share_requirements, https://help.loomio.com/en/user_manual/polls/quorum) [P/S]
+- Quorum is optional, a percentage of eligible voters; set per poll or per poll template.
+- Vote-share requirements are separate: threshold measured against eligible voters or votes cast; weighted voting uses weight instead of headcount; a Block option with "no more than 0%" lets one block vote prevent passage.
+- Docs example: 5 eligible, 75% agreement of eligible plus 60% quorum; 2 agreeing votes (40% of eligible) fail.
+- Closing: deadline can be extended or proposal closed early; no built-in minimum open period found; group-written rules vary (one group: >=50% of reps participate, open two weeks) (https://www.loomio.com/d/tmaQYcM5/proposed-changes-to-the-loomio-voting-process-for-e-nable-proposals) [S].
+
+Debian constitution (https://www.debian.org/devel/constitution) [P]
+- GR: discussion period min 2 weeks, max 3 (App. A.1.1); voting period 2 weeks, Leader may vary by 1 week (4.2.3); quorum 3Q where Q = half sqrt(number of Developers); casting vote for Leader; default option "None of the above" (4.2.4); ranked ballot, Condorcet/Schwartz-set counting (App. A.5).
+- Sponsorship needed to propose a GR: K = min(Q, 5) (4.2.1, 4.2.7). 2K sponsors can put a Leader/Delegate decision on hold (4.2.2).
+- Supermajorities: 3:1 for constitutional amendments and foundation documents (4.1.2, 4.1.5.3); 2:1 to override a Technical Committee decision (4.1.4).
+
+Robert's Rules small boards [S]
+- Default quorum is a majority of the membership unless bylaws say otherwise (https://www.dummies.com/article/business-careers-money/business/general-business/roberts-rules-for-defining-a-quorum-189712, https://mtas.tennessee.edu/system/files/mrln/mknowledge/main/Quorum_Hodge_2018_public_legop.pdf).
+- "Small board" relaxed procedure applies to bodies of about 12 or fewer (https://www.wv-wmd.org/polity/smallboards.html). The search did not confirm any finer threshold.
+
+Decidim (https://docs.decidim.org/en/develop/admin/components/proposals) [S]
+- Proposals component settings include per-participant vote cap, minimum votes per user (below it votes do not count), acceptance threshold per proposal, and an option to keep collecting votes after threshold. Version-dependent. Decidim's closing/quorum semantics for formal decisions were not found.
+
+Low-turnout evidence (DAOs, large N, not small groups):
+- Average DAO participation 6.3% (review, source study unnamed) and ~17% of voting tokens delegated, clustered on popular delegates, across 18 Ethereum DAOs (https://www.frontiersin.org/journals/blockchain/articles/10.3389/fbloc.2025.1598283/epub, https://arxiv.org/pdf/2510.05830) [S].
+- Feichtinger, Fritsch, Vonlanthen, Wattenhofer, "The Hidden Shortcomings of (D)AOs", 21 DAOs: high voting-right concentration (https://arxiv.org/pdf/2302.12125v2.pdf) [S].
+- Compound Proposal 289 (July 2024) passed 682,191 to 633,636 with <7% of COMP supply; an earlier proposal 279 failed with 88% against; reported as an alleged governance attack, resolved by a negotiated cancellation (https://thedefiant.io/news/defi/compound-governance-attack-reveals-inherent-vulnerabilities-of-daos, https://www.theblock.co/post/307943/24-million-compound-finance-proposal-passed-by-whale-over-dao-objections, https://coindesk.com/business/2024/07/30/comp-token-rises-as-whale-backs-down-on-supposed-governance-attack-on-compound) [S].
+- No source located that specifically studies stalled/quorum-busting motions in groups of ~10-20. Not found, not proven absent.
+
+## 2. Vote weighting; mixed human/AI voting
+
+One-member-one-vote vs weighted:
+- Beanstalk (Apr 2022): flash-loaned voting power passed BIP-18/19 and drained ~$76M actually stolen (headline $182M); causes cited: no flash-loan-resistant vote measurement, no execution delay (https://www.bleepingcomputer.com/news/security/beanstalk-defi-platform-loses-182-million-in-flash-loan-attack/, https://rekt.news/beanstalk-rekt, https://www.merklescience.com/blog/hack-track-analysis-of-beanstalk-flash-loan-attack) [S].
+- OpenZeppelin Governor: voting power read from a past snapshot (ERC20Votes checkpoints), voting delay lets members exit before the snapshot matters; quorum as a fraction of supply at snapshot, only For+Abstain count (https://docs.openzeppelin.com/contracts/5.x/governance) [P].
+
+Quadratic voting:
+- Lalley and Weyl, "Quadratic Voting: How Mechanism Design Can Radicalize Democracy" (https://papers.ssrn.com; also https://bfi.uchicago.edu/wp-content/uploads/2016-14-1.pdf); Posner and Weyl 2017 survey (https://www.Gwern.net/doc/economics/mechanism-design/quadratic-voting/2017-posner.pdf) [S].
+- Weyl argues collusion/fraud is deterred except at very large scale (https://www.microsoft.com/en-us/research/?p=893088) [S]; Rivest's note argues QV is inherently susceptible to collusion [S].
+- Sybil/wallet splitting defeats the quadratic cost without proof of personhood (https://www.spark.money/glossary/quadratic-voting) [S].
+- "Concave is the New Linear: The Impossibility of Anti-Plutocratic DAO Governance" (https://arxiv.org/pdf/2605.18990) [A, 2026]: title states an impossibility claim; body not read.
+
+AI agents in governance (2025-2026):
+- DAO-AI, arXiv 2510.21117 (https://arxiv.org/html/2510.21117v2) [A]: multi-agent analysis of proposals/forum/voting; reports interpretable, auditable signals; agentic AI as decision-maker study.
+- QOC DAO, arXiv 2511.08641 (https://arxiv.org/html/2511.08641v1) [A]: roadmap human-only -> agents simulate stakeholders with humans holding final authority -> AI-driven DAO.
+- "Who Controls the Collective AI Vote? Real-World Evidence and Adversarial Testing of Multi-Agent Delegation in DAO Governance" (https://neurips.cc/virtual/2026/165281) [A]: several visible agents may share one actor controlling instructions, evidence, software, signing or reversal; combines analytical model, public-record audit of three deployed systems, tests of three voting rules, open-model replay; reports separating untrusted proposal text from governing instructions cut targeted vote changes in one fixed model; controller separation reduced common-input attacks but not direct compromise of one agent; layered safeguards lowered all four channels.
+- Blockful ENS AI Delegate experiment: agents on own servers vote from bias prompt + DAO constitution + proposal (https://blockful.notion.site/AI-Delegate-8296ff74623a4078b1ab7e7536adfabf) [S].
+- Arbitrum RFC on "Agentic Governance Pivot": community asked for how agents work and a public vote-history dashboard (https://forum.arbitrum.foundation/t/rfc-proposal-to-adjust-the-voting-power-of-the-arbitrum-community-pool-ratifying-the-agentic-governance-pivot/29280/11) [S].
+- Epistemic delegation paper mentions a possible block of AI "Condorcet agents" as imagination-stage (https://arxiv.org/pdf/2505.04136) [S].
+- Trustless Autonomy, arXiv 2505.09757: interview study, governance dilemma of unreliable agents (https://www.arxiv.org/pdf/2505.09757) [S].
+- No study found of small mixed human/AI-agent boards voting on operational settings of their own system.
+
+## 3. Sybil and correlated voters
+
+- Kohli, "Nine Judges, Two Effective Votes: Correlated Errors Undermine LLM Evaluation Panels", arXiv 2605.29800 (https://arxiv.org/abs/2605.29800; Apple ML research page https://machinelearning.apple.com/research/correlated-llm-evaluation-panels) [P abstract]: 9 frontier LLMs from 7 families on three NLI datasets carry ~2 independent votes (Kish n_eff); panel accuracy 8-22 points below independent-voting expectation; best single judge matches or beats panel; aggregation methods close at most 11% of the gap; holds across prompts, temperature, CoT, a pairwise-preference task. Abstract does not split same-family vs cross-family; narrow task domain; preprint, review status unverified.
+- STRIVE, arXiv 2608.04567 (https://arxiv.org/pdf/2608.04567) [S]: failing-group jury 33% vs best member 47%; some items missed by every configuration.
+- Theory: Condorcet jury theorem assumes independent voters; Austen-Smith and Banks (1996) showed independence is necessary for the aggregation benefit (cited in Kohli) [S]. Explainer: https://towardsdatascience.com/your-six-ai-models-are-really-two-the-math-of-correlated-mistakes/ [S].
+- Controller concentration across visible agents: the NeurIPS "Who Controls..." abstract above [A].
+- IETF names vote stuffing as a failure mode of voting-style consensus (RFC 7282, above).
+- Compound 289: delegated voting power concentrated in one delegate authored successive proposals (sources in section 1) [S].
+- Not found: any study of one operator running several personas on the same base model as voters specifically (closest: Kohli, NeurIPS abstract).
+
+## 4. Delegated or tiered authority
+
+Apache (voting.html above) [P]: PMC binding; non-PMC advisory; decision type determines threshold; code vetoes need technical justification.
+
+Rust:
+- RFC 1068 governance (https://github.com/rust-lang/rfcs/blob/master/text/1068-rust-governance.md) [P via summary]: subteams own RFCs in their area (shepherd, accept/reject, policy on what needs an RFC); core team sets direction, creates/shuts subteams; consensus is the norm; for minor disputes shepherd or leader decides; deep disagreement: leader decides after consulting core team; final comment period one week in that RFC text; new technical arguments raised in FCP trigger another comment period; each subteam sets its own rules for when an RFC is required.
+- Compiler FCP page (https://forge.rust-lang.org/compiler/proposals-and-stabilization.html) [P]: FCP needs team sign-off, then a ten-day wait; outstanding concerns block completion (`@rustbot concern` / `resolve`), countdown restarts when concerns resolve; FCP can be skipped for easily reversed MCPs. The page did not describe the disposition (merge/close/postpone) or majority-of-team checkbox mechanism; those were not verified.
+
+Debian (constitution above) [P]:
+- Individual developers decide their own work (3); Leader delegates (5.1.1, 8); delegation irrevocable once a specific decision is made (5.1.1); Leader cannot override a Delegate's made decision (8.2); GR can override Leader/Delegate (4.1.3) and TC (2:1, 4.1.4); TC decides last-resort, overrule Developer by 3:1 (6.1.4, 6.3.5); Secretary runs votes and interprets (7.1).
+
+Kubernetes KEP (https://www.k8s.dev/resources/keps/5241/, https://kubernetes.io/blog/2020/08/21/moving-forward-from-beta/) [S]: owning-SIG approvers move a KEP provisional -> implementable; significant later changes need every approver; graduation criteria are written into the KEP; stages alpha (off by default), beta (usually on, can be disabled), GA (always on).
+
+Loomio: block option as per-option veto (above).
+
+## 5. Binding a decision to a parameter change
+
+- Compound Governor (https://docs.compound.finance/v2/governance/, https://wiki.tally.xyz/docs/compound-governor) [S]: passed proposal queued in a Timelock, executable after 2 days; voting delay and period are themselves parameters changeable through governance; a Pause Guardian can act without a vote; Olympus's Bravo deployment adds a veto guardian who may veto any time before execution (https://docs.olympusdao.finance/main/contracts/docs/src/external/governance/GovernorBravoDelegate.sol/contract.GovernorBravoDelegate) [S].
+- OpenZeppelin Governor + TimelockController [P]: delay "allows users to exit the system if they disagree with a decision before it is executed"; roles proposer (the Governor only), executor (may be anyone), canceller, admin (to be renounced after setup); extra proposers/cancellers flagged as a risk of bypassing or blocking governance; optional proposal threshold limits who can propose. Guardian extension lets a guardian cancel at any stage (https://docs.openzeppelin.com/contracts/api/governance) [S].
+- Beanstalk had no execution delay (section 2 sources) [S].
+- MakerDAO Governance Security Module delay and executive-vs-poll split: fetch redirected to https://developers.skyeco.com/ and was not read; not verified here.
+- Compound 290 plan: team multisig deploying a new Governor to strip a delegate's power (reported intent, later cancelled) (sources in section 1) [S].
+- Kubernetes: parameters change via feature gates whose default flips at KEP graduation stages, decided by SIG approvers, not vote (section 4) [S].
+- Feature-flag change-control (LaunchDarkly approvals, etc.): not searched.
+
+## Not covered or unverified
+- Maker GSM, ASF "lazy majority"/2:3 definitions, Rust FCP disposition and majority-checkbox rule, Decidim formal-decision close semantics, feature-flag approval workflows, full text of every [A] paper, same-family LLM correlation numbers, anything on stalled-motion rates in small boards.

Minds / Members / Users / Patrons blocks exist only as rulings (section 5).
+- Closest code analogues: `MembershipStatus` (Authenticated ~ Users, Active ~ Members), `TierSnapshotKind.Patron`. No Persona/Mind account class; `BridgeActorKind` Member|Agent|Persona|Service (BifrostModels.cs:178) is for bridge actions only (research note Part 1).
+
+### 1c. How a person joins today
+- Invite-only alpha (README "Alpha Scope"). `MembershipInvitation` (BifrostModels.cs:406) keyed on normalized GitHub login (MembershipSynchronizationService.cs: invitation lookup by NormalizedGitHubLogin). Admin invites at Pages/App/Members `OnPostInviteAsync` (Index.cshtml.cs:34); invited GitHub sign-in becomes PendingApproval; admin `OnPostApproveAsync` (l.92) sets Active, ApprovedAtUtc, StandardMember role. Also OnPostToggleRoleAsync (l.127), OnPostSetTierAsync (l.184), OnPostUpdateProfileAsync (l.240).
+- Un-invited GitHub or native sign-in stays Authenticated. Bootstrap admins by GitHub login via `Bootstrap:AdminGitHubLogins` become Active admin automatically.
+- Heimdall path: Discord role (KTLST guild role) or Patreon tier title (`Inner Sanctum`) entitlement grants Active (HeimdallAuthService.cs ~l.296-324; docs/app-profiles/bifrost.md in Heimdall).
+- /App is ActiveMember-gated (Program.cs:57 per research note).
+- No application form, no customer/client type, no contract record, no related-party flag, no email invite (invitations are GitHub-login keyed), no self-service for a person without GitHub, Discord-guild role, or Patreon tier.
+
+### 1d. Vote weighting in code (not the ruled design)
+- `Membership.EffectiveVotingWeight` = 0 unless Active, else `Math.Max(1, sum of current TierSnapshot weights)` (BifrostModels.cs:357-361).
+- Patron tiers (Features/Patronage/PatronTierPolicy.cs): Bronze 10 pts w1, Silver 100 w2, Gold 1,000 w3, Platinum 10,000 w4, Unobtanium 100,000 w5. Points from `PatronSupportEvent` amounts; one-time donations: full for 30 days, then 50% decayed 1%/week; recurring snapshots count while current; adjustments added (GetHistoricalDonationPoints). `PatronSupportEvent` carries ProjectId, provider (Manual|Patreon|PayPal|Stripe), currency code, amount.
+- Contributor points: `PointTransaction` (BifrostModels.cs:773; types ManualAdjustment, ApprovedWork, ContinuousRoleCredit, PatronSupport, Decay). Contribution-to-vote scaling: no code found that scales vote weight by contribution beyond TierSnapshot kind Contributor set by admin (OnPostSetTierAsync).
+- No log or exponent curve anywhere in src (grep Math.Log/Sqrt empty). Rulings `governance-vote-power-scaling` (log patrons, lower exponent members) are not implemented.
+
+### 1e. Motions, brake, timelock (code)
+- `Motion`/`Vote` Postgres rows (BifrostModels.cs:665, 702). MotionGovernanceService.cs: CreateMotionAsync (:13), CastVoteAsync (:47; weight copied from actor at cast time), CloseMotionAsync (:95; manual, by creator or CanModerateMotions). Pass = For/(For+Against) >= ApprovalThreshold, abstain excluded; no quorum.
+- Thresholds (MotionCategoryPolicy.cs; research note): Bugs .15, Cosmetics .30, Balance .40, Features .50, NewContent .50, FundamentalDesign .66.
+- Brake and timelock: absent. `git grep -i -E 'timelock|brake|quorum'` in src/ returns nothing. They exist only as rulings. `motion.create/vote/close` command names appear in MotionEveSurfaceService with no handler (research note Part 1). Only machine surface: GET `/eve/governance/surface` (Program.cs:513), deprecated Eve JSON. Motions are not typed CultMesh state.
+- Docs: docs/verse-service-contract.md lists schema `gamecult.bifrost.governance`; motion/vote schema ids marked todo (:256 per research note).
+
+### 1f. Other Bifrost surfaces relevant to a customer
+- Stripe: `StripeOptions` (Configuration/StripeOptions.cs; EnableCheckout, SecretKey, WebhookSecret, GeneralPatronageGitHubLogin, Success/Cancel URLs default to velvet.gamecult.org); routes GET `/patronage/{project}/checkout` (Program.cs:431) and POST `/patronage/stripe/webhook` (:489); Webhook records a `PatronSupportEvent` against the configured GeneralPatronageGitHubLogin account.
+- PayPal/Patreon: docs/paypal-patronage.md: Heimdall POSTs HMAC-signed support facts to `/heimdall/patron-support/events` (Program.cs:408). "PayPal owns money movement... Bifrost owns patronage meaning".
+- Ledger (`LedgerEntry` types PatronCredit, ContributionCredit, NominalCompensation, Adjustment; payout proposal batches). README: "no real payout execution in v1"; "internal ledgers only".
+- OIDC issuer for Matrix chat (docs/oidc-issuer.md; main 1894f65/83daabe): Bifrost is the identity issuer; back-channel logout reconciler ends sessions of non-Active subjects (OidcLogoutReconciler). Remaining scar: Heimdall still mints its own account id.
+- Concept Mill votes (ConceptVotes/*, VoterClass Anonymous|Account|Member): per-subject appraisals, not motions.
+
+### 1g. Documented gaps
+- Swarm research note (docs/research/2026-10-29-swarm-governance-prior-art.md Part 1) and follow-up `eureka-body:follow_up:swarm-governance-on-bifrost` item text: no quorum; manual close only; Personas cannot be Active members or vote; motions/votes are Postgres rows not typed CultMesh state; only machine surface is deprecated Eve JSON; motion.* commands without handler; no Matrix surface; Yggdrasil behind main.
+- README "Next Build Target" and docs/full-implementation-strategy.md l.11: "not an internet-facing alpha"; payout proposals, revenue-share automation, decay automation, GitHub App guidance are future. No single "gaps list" file found.
+
+## 2. Heimdall (F:\Projects\Heimdall; TypeScript/Fastify; in-memory + Postgres stores)
+- Providers (src/contracts.ts:1): discord, patreon, github, twitch, youtube, spotify, joystick.
+- App profiles (src/app-profiles.ts): repixelizer (identity discord, patreon); streampixels (identity twitch, youtube; managed connection twitch, youtube, joystick; allowedReturnOrigins streampixels.gamecult.org); bifrost (identity+entitlement discord, patreon; l.138-143); ghostlight (discord). Built-in app slugs are "seed data, not the set of permissible apps" (contracts.ts comment).
+- Bifrost integration (docs/app-profiles/bifrost.md): Bifrost starts Discord or Patreon OAuth with a server-owned entitlement policy over `backend_callback`; Heimdall delivers to `https://bifrost.gamecult.org/auth/heimdall/callback`; Bifrost creates/updates UserAccount, activates standard membership, issues its own cookie. Patron sync: POST `/v1/apps/bifrost/patron-support/sync` -> signed RecurringSupportSnapshot to Bifrost. Heimdall does not own ledgers, points, votes.
+- Bifrost's own AllowedProviders is discord, patreon only (HeimdallAuthService.cs:37-40). Twitch/YouTube are not Bifrost sign-in providers; Heimdall's bifrost profile does not list them. GitHub is signed in by Bifrost directly, not through Heimdall.
+- Non-technical external person today: could sign into Bifrost with a Discord account holding the KTLST role in the GameCult guild (Active at once), or a Patreon account with an active `Inner Sanctum` tier (Active at once), or GitHub if invited by login, or native register (identity string, lands Authenticated, no vote). No email/password/magic-link sign-in exists in Heimdall's provider list. Whether the live Heimdall has Discord/Patreon creds configured: runbooks/heimdall-discord-launch.md and bifrost-alpha-deploy.md say configured (inventory.md:1019 "Heimdall-mediated Discord/Patreon access and Patreon support intake env are configured"); live check not done.
+- Heimdall state map (state/map.yaml l.62-63, 129-130): live release d51fa6b (hand-deployed 2026-10-19) includes Joystick H1; remaining: human canaries, refresh/revocation, admin surfaces.
+- Joystick consent work (open): `joystick:follow_up:h1-joystick-consent-round-trip` (the streamer completes a Joystick connect consent through a creator-bound streampixels connect start on live Heimdall d51fa6b; verify a joystick linked identity keyed by channel_id). StreamPixels map.yaml open_operator_decisions: "Joystick S0/S1: the streamer's consent click is still owed before the connector goes live". Joystick is a managed creator connection only, not a viewer sign-in (docs/app-profiles/streampixels.md; `joystick:ruling:signin-waits-for-public-bot`). Other Joystick follow-ups in docs/architecture.md:442-457: cross-process-failed-refresh-marker, connect-start-needs-app-auth, heimdall-idunn-onboarding, joystick-viewer-signin-public-bot.
+- Open High finding relevant to identity linking: `gamecult-chat:follow_up:streampixels-link-target-takeover` (InForce): an unauthenticated Heimdall link start for streampixels can name any profile id; StreamPixels redeem links with no session check; Plausible High, unconfirmed.
+
+## 3. StreamPixels (F:\Projects\StreamPixels, state/map.yaml, state/evidence.jsonl)
+- Engagement (map.yaml l.17-70): the StreamPixels client; `budget_eur: 1500`; split even, EUR 500 per milestone (operator 2026-09-14; currency corrected from USD by operator 2026-10-25); milestones M1 "whole system running end to end on her stream" (September), M2 committed 2026-09-15: GPU fixed-capacity particle pool and AquaSynth impact audio (October), M3 TBD sold by proposal (November). Cadence: "The operator needs one milestone paid per month to survive." evidence.jsonl l.16 records the engagement (written as "$1,500" on 2026-09-14).
+- Recorded money status: map.yaml has no field recording a milestone as invoiced or paid; no invoice/payment/received hits in map.yaml or evidence.jsonl (grep). Milestone completion state: M1 still in progress per `focus: milestone-1-unity-repair` and active_subgoals (A3b, C1 remaining, l.153); the map.yaml read ended before the full active_subgoals/next_action sections.
+- Consent: map.yaml `consent`: "Her channel is not a marketing asset. Publicly associating her with the overlay requires asking her."
+- Business context l.60-66: "She has explicitly ruled out microtransactions".
+- Heimdall/Bifrost identity for the client: no Bifrost or Heimdall account, user id or invitation naming the client or her streamer handle found. Searched Bifrost and Heimdall for the client's and streamer's handles: no account or invitation found. Her Heimdall identity, if any, lives in live DB (not checked). StreamPixels has creator memberships and linked identities in its own store (apps/service/src/app.ts ~l.698, 1491-1602) via Twitch/YouTube/Joystick; live contents not checked.
+- StreamPixels forks stay in chat, no Kiko desk: `web-customize:ruling:sp-forks-in-chat-until-thing2` (2026-10-26).
+
+## 4. Payment / invoicing / money received
+- Recorded payment-receiving surfaces: Bifrost Stripe checkout+webhook (patronage; runbooks/bifrost-alpha-deploy.md:84-98 lists `Stripe__EnableCheckout`, `Stripe__SecretKey`, `Stripe__WebhookSecret`, `Stripe__GeneralPatronageGitHubLogin`; whether live-enabled unknown, inventory.md has no Stripe flag); Heimdall-signed Patreon and PayPal support facts (docs/paypal-patronage.md); StreamPixels donation source Ko-fi webhook (map.yaml settled decision, for streamer donations, not for the operator's fees).
+- No invoicing surface found: grep of gamecult-ops (excluding repo-census docs) for invoice returns nothing; Bifrost has no invoice entity (LedgerEntry/Payout are internal, "no real payout execution", "internal ledgers only"). `PatronSupportEvent` is the nearest "money received" record (amount, currency, provider, externalSupportId, ProjectId) and drives patron voting points; there is no contract/engagement/client-payment event kind (kinds: OneTimeDonation, RecurringSupportSnapshot, SupportAdjustment; providers Manual, Patreon, PayPal, Stripe). A Manual provider event can be admin-entered.
+- Treasury: `eureka-body:follow_up:swarm-treasury-and-revenue` (InForce): typed runway document (balance, committed costs, expected income) "The operator enters figures; no bank credentials are ever handled by agents"; not built. Owner repo GameCult/gamecult-ops. Source ruling `eureka-body:ruling:operator-legal-vehicle-shared-solvency` (operator is GameCult's legal and financial vehicle; her bank account pays for server and tokens).
+- Operator's bank/payment record for the EUR 1,500: not recorded in any file read.
+
+## 5. The mind (ids)
+Follow-ups (all InForce, campaign eureka-body):
+- `eureka-body:follow_up:swarm-governance-on-bifrost` (admitted 2026-10-29T20:45Z).
+- `eureka-body:follow_up:co-op-charter` (2026-10-29T21:13Z): one typed charter document in Bifrost with every governed parameter (estates and weights, within-estate curves and exponents, operator influence cap, bloc position rule, quorum, category thresholds, close timing, decision delay and cancel); amended by motion, higher threshold for charter amendments (Debian 3:1 cited). Gathers rulings governance-estate-blocks, governance-vote-power-scaling, estate-weights-normalize-by-turnout, swarm-decides-without-operator, operator-influence-below-half, swarm-governance-in-bifrost, desk questions 37, 38, 40, 41. Not on bring-up path; operator holds the seat until Bifrost governance is live.
+- `eureka-body:follow_up:swarm-treasury-and-revenue` (2026-10-29T21:24Z): treasury runway doc plus a revenue-map Eyes pass.
+Rulings (Operator, InForce):
+- `eureka-body:ruling:governance-estate-blocks` (10-29): four blocks Minds (Personas), Members (Active members), Users (authenticated accounts), Patrons (patron tiers); each block's internal vote gives its position; block weights are governed settings changed by motion. The ruling lists no Customers estate.
+- `eureka-body:ruling:estate-every-estate-equal-seed` (10-29, answers `estate-overlap-and-seed`): a person votes in every estate they belong to; estates start at equal weight.
+- `eureka-body:ruling:estate-bloc-parliament-at-threshold` (answers `estate-bloc-position`): each estate casts whole weight For only if its internal For share meets the category threshold; known cost: low categories rescaled before go-live (0.15 passes on 3.7% overall support).
+- `eureka-body:ruling:estate-weights-normalize-by-turnout` (10-29): only estates where someone voted count; weights renormalized to sum 1; empty estate drops out.
+- `eureka-body:ruling:governance-vote-power-scaling` (10-29): patrons by strongly flattened log of donation total; members by contribution with a lower exponent; curves and exponents governed; exact functions "a sketch to be calibrated by simulation (her numbers are feel, not gates)"; replaces `max(1, tier weight)` when the governance cut lands.
+- `eureka-body:ruling:operator-influence-below-half` (10-29; supersedes `operator-influence-capped-at-half`): strictly less than half; mechanism and number from simulation; a governed parameter. Research: Bifrost docs/research/2026-10-29-estate-tally-game-theory (18bbe6c adds bloc-parliament-at-threshold and operator influence cap; present case Members = her alone, Minds 8, Users/Patrons empty, README l.84).
+- `eureka-body:ruling:swarm-decides-without-operator` (10-29): no quorum rule may require her vote; rules out at-least-two-estates floor.
+- `eureka-body:ruling:motion-deadline-quorum-autoclose` (10-29, answers `motion-quorum-and-close`): default 72h window; Bifrost auto-closes; quorum is a majority of eligible voters.
+- `eureka-body:ruling:brake-to-bifrost` (10-29; quote: "hand the brake to bifrost") and `eureka-body:ruling:brake-anyone-pulls-motion-releases` (answers `brake-engage-release`): any Mind or human member engages the brake at once, every pull published with reason; releasing takes a motion (short window, e.g. 24h, majority); until Bifrost governance is live the brake stays in the root-owned swarm control store (`eureka-body:ruling:brake-dial-root-store-now`, 2026-10-02).
+- `eureka-body:ruling:decision-timelock-owner-applies` (answers `decision-applies-how`): passed motion published as typed CultMesh state with an effective time (e.g. 24h); the owning service applies it then; cancellable until then; who may cancel follows brake-to-bifrost and the charter (operator holds no private cancel).
+- `eureka-body:ruling:swarm-governance-in-bifrost` (2026-10-10); `swarm-shares-log-bound`; `swarm-membership-operator-rules` (operator rules births/retirements/transfers; any mind proposes; a mind may leave).
+- `eureka-body:ruling:operator-legal-vehicle-shared-solvency` (10-29); `eureka-body:ruling:customers-get-voting-power-onboarding-owed` (10-30).
+- Withdrawn question `eureka-body:question:persona-vote-weight` (replaced by estate blocks); withdrawn `estate-internal-tally` (restated as `estate-bloc-position`).
+- "Kiko rulings": the 2026-10-29T21:41:40Z batch (ordinal 4430) answering desk questions: estate-overlap-and-seed, estate-bloc-position, brake-engage-release, decision-applies-how, motion-quorum-and-close. No separate document labeled Kiko beyond these and `web-customize:ruling:sp-forks-in-chat-until-thing2`.
+- No ruling or follow-up found on: a Customers estate, related-party/conflict-of-interest handling for a customer who is a related party, customer vote weight from contract value, a customer onboarding workflow (other than the 10-30 ruling), or a co-op charter document existing yet (semantic query top hits showed none).
+- Joystick: `joystick:campaign:self`, `joystick:follow_up:h1-joystick-consent-round-trip`.
+
+## 6. What Yggdrasil runs for Bifrost
+- gamecult-ops inventory.md:1021: live release `/srv/bifrost/app/releases/20261010043032-67072b2`, revision `67072b28923017f93f484d901c7a6d31e3678d88`, deployed 2026-10-10; app user `bifrost`, root `/srv/bifrost/app`, env `/srv/bifrost/env`, bound `127.0.0.1:5080` via `bifrost.service` behind nginx (`bifrost.gamecult.org`, TLS issued 2026-06-10), local PostgreSQL 16. Heimdall-mediated Discord/Patreon access and Patreon intake env configured (l.1019).
+- Distance: `git rev-list --count 67072b2..origin/main` = 94 today (follow-up text says 89 at 2026-10-29). Commits since 67072b2 touching src/: OIDC issuer for Matrix chat (83daabe, 404dafd), Heimdall sign-in cookie ring and signed callback (15f96c4, b7e3bdf, b2110f5), Mill votes sign-in offer (cf74019), NuGet pins/lockfiles, mouth-all-personas (cc76f0f, tools/). So OIDC issuer and the newest Heimdall sign-in hardening are not live.
+- Also on Yggdrasil from Bifrost: `bifrost-persona-feedback.service`, `bifrost-persona-mouth.service`, `bifrost-watchdog-notice` timer (inventory.md:710-729; Persona delivery via Discord per that inventory text; main now moves Persona speech to Matrix per docs/bridge.md:199). Whether the Stripe/Heimdall env flags are live was not verified (no ssh).
+- Deployment authority is Idunn for managed workloads; Bifrost deploy is by `scripts/deploy-bifrost-alpha.sh` / runbooks/bifrost-alpha-deploy.md per inventory (interim); not confirmed which path produced 67072b2.

+# Customer-member onboarding: prior art
+
+Served: eureka-body:ruling:customers-get-voting-power-onboarding-owed (2026-10-30), the forks on customer estate, weight, decay, related parties and join flow. Eyes pass, facts only; [U] marks unverified.
+
+# Eyes facts: customer onboarding and voice in multi-stakeholder / platform co-ops (2026-10-30)
+
+Method: web search result summaries plus two WebFetch attempts. Most facts come from search-result summaries, not full-page reads. "[V]" means the source was returned by search and the claim is stated there; "[U]" means unverified, conflicting, or not found. No primary statutory text was retrieved (both wetten.overheid.nl fetches returned only tables of contents / metadata).
+
+## Q1. Admission and classes in multi-stakeholder and platform co-ops
+
+- Stocksy United [V]: three classes. A = advisors on board, capped at 5, may buy up to 200 shares (one support page). B = staff, may buy one extra B share a year. C = contributing artists, max one $1 share. Class C cap of 1,000 was removed by member resolution (support docs date it 2018). Patronage for A and C is not tied to share count. Members can submit resolutions. Sources: https://stocksy.com/legal/rules ; https://support.stocksy.com/hc/en-us/articles/201658696 ; https://support.stocksy.com/hc/en-us/articles/201659716-Is-there-a-limit-on-the-number-of-Co-op-members ; https://geo.coop/content/stocksy-united-removes-its-membership-cap ; https://support.stocksy.com/hc/en-us/articles/201808247-Can-members-purchase-more-shares-in-the-Co-op
+- Stocksy: the 1,000 cap led to regular review and removal of inactive members (company announcement via https://gdusa.com/stocksy-member-owners-open-door-to-new-contributors/) [V, secondary].
+- Fairbnb [V, partly planned]: intends to admit hosts, guests, local businesses, neighbours; per a 2020-era description workers and advisors are members, local partners/users/hosts "in the foreseeable future"; funders' voting power is statutorily limited to one third of assembly votes. Another source says it currently operates as a worker co-op without hosts. Italian and Spanish co-op law reportedly makes multi-stakeholder creation from scratch hard. Sources: https://www.thenews.coop/can-fairbnb-become-a-platform-for-community-powered-tourism/ ; https://wiki.p2pfoundation.net/FairBnB . Current composition [U]; one source is a promotional travel blog.
+- Resonate [V, one interview, other figures conflict]: three voting classes, Music-Makers 45%, Fans 35%, Collaborators 20% (Peter Harris interview), plus a Founder class with early board-appointment say. Listener membership 5 EUR/yr (Billboard). Source: https://www.resilience.org/stories/2018-06-15/resonation-an-interview-with-peter-harris/ ; https://geo.coop/content/own-music-you-stream-resonate .

Sources: https://en.wikipedia.org/wiki/Eva_(coop%C3%A9rative) ; https://wiki.p2pfoundation.net/Eva_Coop . Up & Go: described as worker-owned cleaners' co-op in NYC; no membership-class details found [U].
+- Open Food Network [V]: governance as collective of affiliates under a "global pledge"; Open Food Foundation oversees governance and finance; UK arm "co-op of co-ops" with food hubs, farmers, shoppers as members, sociocratic circles. Sources: https://www.openfoodnetwork.org/about-us/ ; https://www.uk.coop/blog/open-food-network-making-food-systems-fair-and-sustainable-unfound . No customer admission steps found [U].
+- Eroski/Mondragon [V]: worker-members and consumer-members; General Assembly of 500 delegates, 250 worker and 250 consumer; 1.3M+ consumer members (2022). Surplus: 40% to worker-members, 50% reserves, 10% COFIP (2026 assembly). Consumer-member fee (~$75/yr) from older source [U]; per-member consumer vote weight not found [U].

+- REI [V, secondary]: lifetime membership $30 one-time (older $15/$20); dividend now "Co-op Member Reward" (patronage dividend and/or promotional reward, decided annually); historically ~10% of regular-price spend; ballot for board election sent with dividend notice. Older rule: active member = paid fee and bought >= $10 in a calendar year [U for current]. Sources: https://www.rei.com/membership ; https://www.rei.com/membership/join ; https://www.nbcnews.com/select/amp/rcna172651
+- Quebec solidarity co-ops [V]: classes user members, worker members, supporting members (1997 amendment). Required share count may differ by class; rebates to users by business done, to workers by work volume; supporting members get no rebate. Voting formula not found; set in by-laws [U].

+- Not found: Fairbnb/Resonate/Eva application-and-approval steps and member agreement text [U].
+
+## Q2. Purchase-based voice, plutocracy, dominant customer, related parties
+
+- Ag co-ops (US) [V, 1990s-2003 sources]: 93% of direct-membership co-ops used one-member-one-vote, 7% proportional (patronage-based extra votes) per a 1997 USDA report. Capper-Volstead exemption described as conditioned on one-vote-per-member or an 8% dividend cap (secondary summary; Texas AG opinion reads its state version as flat one-vote). State statutes largely determine which is allowed. Arguments: proportional voting for those with more equity at risk; one-member-one-vote as cooperative democratic principle, which IRS has generally endorsed. Statute text not retrieved [U]. Sources: https://www.rd.usda.gov/sites/default/files/rr156.pdf ; https://aglawjournal.wp.drake.edu/wp-content/uploads/sites/66/2016/09/agVol01No2-Matthews.pdf ; https://nationalaglawcenter.org/wp-content/uploads/assets/bibarticles/royer_principles.pdf ; https://le.utah.gov/~2003/bills/sbillenr/SB0142.htm
+- Patronage dividends vs voice: Stocksy A/C and REI/Quebec rebates tie money to patronage while voting stays per-member or per-class (see Q1 entries). Quebec supporting members get no rebate.
+- Multi-stakeholder co-ops [V]: typically one-member-one-vote within a class, fixed board seats per class; minimum and maximum vote shares per class suggested to harmonise interests; allocation of governance rights between classes is a key drafting decision; a customer member may have less "skin in the game"; boards should adopt conflict-of-interest policies.

+- Fairbnb's funder cap (one third of assembly votes) is a class-level vote ceiling (Q1 source).
+- Concave weighting and plutocracy [V, preprints]: arXiv 2605.18990 "Concave is the New Linear: The Impossibility of Anti-Plutocratic DAO Governance" argues quadratic or any concave mechanism cannot withstand a Sybil adversary on permissionless chains (power grows at least linearly in holdings).

+- Related parties / family member as customer: no source found addressing related-party voting in co-ops [U]. Only the generic conflict-of-interest policy recommendation above.
+- Dominant single customer in a class: no source found [U], other than class-level caps above.
+
+## Q3. Digital governance tooling
+
+- Decidim [V]: census authorization by admin CSV import; participants self-initiate verification from profile; authorization handlers are pluggable (SMS code, postal-letter code); CVE-2026-45415 let a limited participant-manager alter census records (fixed in 0.30.9 / 0.31.5 / 0.32.0).

Ephemeral verifications page exists (https://docs.decidim.org/en/v0.31/admin/participants/authorizations/ephemeral_verifications), not read. Revocation behaviour not retrieved [U].
+- Loomio [V]: email invite with single-use link; join requests need coordinator approval depending on privacy; reusable link bypasses approval. Source: https://help.loomio.com/en/user_manual/groups/inviting_people/index.html . No weighted voting or expiry found [U].
+- Snapshot / token DAOs [V]: quadratic voting relies on proof-of-personhood; whales split across wallets; fewer than 20 delegates reportedly hold >50% of power in major DAOs; vote-escrow aligns long-term incentives but is illiquid. Sources: https://blog.tally.xyz/a-simple-guide-to-quadratic-voting ; https://www.spark.money/glossary/quadratic-voting ; https://blockeden.xyz/forum/t/1-of-token-holders-control-90-of-voting-power-across-major-daos-quadratic-voting-delegation-incentives-and-conviction-voting-havent-fixed-the-plutocracy-problem/541 (forum, low rigor).
+- Decay / expiry [V]: EIP-7787 draft proposes token voting-power decay over a fixed 90-day period (draft, not deployed). Colony described as decaying reputation unless members keep contributing. Sources: https://eips.ethereum.org/EIPS/eip-7787 ; https://blog.colony.io/8-essential-voting-mechanisms-in-daos/ .

+- DAOstack [V]: non-transferable reputation earned by contribution; peer-reviewed retrospective "The rise and fall of DAOstack": https://peerj.com/articles/cs-3320 . Decay specifics unconfirmed [U]. Aragon: non-transferable reputation templates; claims about Aragon dissolution and ANT voting removal from a single low-quality source [U].
+- Open Collective: nothing retrieved on backer voting rights or governance [U].
+
+## Q4. Contract-funded versus donation-funded voice
+
+- No literature found distinguishing a paying client class from a patron/donor class [U].
+- Adjacent facts: Dutch sample statutes with donors (donateurs) lacking general-meeting votes (Q5); Quebec supporting members as a non-voting-benefit, no-rebate class (Q1); investor/funder classes as non-user classes with separate caps (Fairbnb, UK rulebook example: https://files.uniteddiversity.coop/Cooperatives/Multi-Stakeholder_Co-ops/go!_rules_v3.0.pdf , from search listing, not opened); Stocksy and REI tie money flows to patronage not votes; Resonate has listener class at 5 EUR/yr.
+
+## Q5. EU / Netherlands legal and consent points
+
+- BW 2:53: coöperatie is an association founded by notarial deed, at least two members at founding, no max (https://wetboekplus.nl/burgerlijk-wetboek-boek-2-artikel-53-oprichting-cooperatie-en-onderlinge-waarborgmaatschappij/ , https://www.viajuridica.nl/informatiesoorten/wetstoelichtingen/oprichting-cooperatie-art-2-53-2-54-bw) [V]. Articles on voting (2:38 etc.), 2:53a, member rights: text not retrieved; official page fetches gave metadata only [U].
+- Admission in sample statutes [V]: board decides unless statutes assign it to the general meeting; general meeting can override a refusal; one set requires unanimity of a fully present meeting; one gives board six weeks to answer in writing. Register of members kept by the board, inspectable by members; board may record additional data beyond the list. Voting: one set denies donors votes; another lets non-qualifying members vote on certain proposals.

+- GDPR/AVG for member registers [V, secondary]: common lawful basis cited is Art. 6(1)(b) (performance of membership agreement), sometimes plus consent for extra data; GDPR sets no fixed retention (AP position quoted), Dutch practice often keeps accounting data 7 years, rest deleted after termination; processing register practically required.

+# Bifrost email mouth: prior art
+
+Served: eureka-body:ruling:payment-mints-invite-bifrost-ledger-email-mouth and the fork on outbound mail (self-hosted SMTP vs transactional provider). Eyes pass, facts only; [U] marks unverified. Gaps not researched: provider suspension behaviour for new senders, DPAs, .NET SDKs, IP warm-up and blocklists, invite/recovery token lifetimes across platforms.
+
+# Eyes: email mouth prior art (2026-10-30)
+[U] = unverified / secondary source only. Web facts came via WebFetch summaries (small-model extraction), not raw page reads.
+
+## Q4 The body (read first, local)
+- Yggdrasil provider: Netcup KVM, 16 vCPU, 62 GiB, Debian 13, ufw active, public ports 22/80/443 only. F:\Projects\gamecult-ops\inventory.md:605,619,629; docs\research\2026-10-22-matrix-stand-up-facts.md:73. Netcup SCP is the console fallback (inventory.md:626).
+- DNS: gamecult.org zone on Hetzner DNS (NS hydrogen/oxygen/helium.ns.hetzner.com); agents hold no Hetzner DNS credential, DNS edits are operator-done; no wildcard, no CAA. gamecult-ops\docs\gamecult-chat-map.md:23; inventory.md:1075,1090; runbooks\forgejo-eureka-yggdrasil.md:24.
+- Other domains: erycina.org exists (runbooks\erycina-org-site-deploy.md, forgejo-erycina-yggdrasil.md); its DNS host not checked [U]. gamecult.com/.net/.dev: no hit in inventory.md.
+- Existing mail setup / MX / SPF / DKIM / DMARC records: grep of gamecult-ops inventory.md, runbooks, docs for MX|SPF|DKIM|DMARC|smtp|postfix|mailgun|postmark|"port 25" found none documented. Only mail mention: runbooks\forgejo-erycina-yggdrasil.md:104 "Mailer - no notifications configured. Enabling it means owning deliverability and an SMTP credential." Live DNS not queried (no dig/DoH run) [U].
+- Port 25 on Yggdrasil: not documented in gamecult-ops; ufw lists inbound ports only. Not tested (no ssh by constraint).
+- Bifrost (origin/main): no Smtp, MailKit, MimeKit, IEmailSender, SendGrid hit in src/*.cs, *.csproj, *.cshtml. Only "email" hit in code: src/Bifrost.Web/Program.cs:187 (GitHub OAuth scope "user:email"). Checkout is Stripe: src/Bifrost.Web/Features/Patronage/StripeCheckoutService.cs, StripeWebhookService.cs, Configuration/StripeOptions.cs; HttpClient to https://api.stripe.com/ (Program.cs:135); route /patronage/{project}/checkout (Program.cs:431).
+- Bifrost UserAccount (src/Bifrost.Web/Domain/BifrostModels.cs:243): fields Id, BifrostIdentity, NormalizedBifrostIdentity, GitHubUserId, HeimdallAccountId, GitHubLogin, NormalizedGitHubLogin, DisplayName, AvatarUrl, CreatedAtUtc, LastSeenAtUtc + nav props (read to ~line 275). No Email field seen. Bifrost currently stores no email per account.
+- docs/research/customer-onboarding-body-facts.md (Bifrost origin/main) :29 "no email invite (invitations are GitHub-login keyed)"; :59 no email/password/magic-link sign-in in Heimdall's provider list; sign-in is Discord role, Patreon tier, GitHub, or native register.
+- Heimdall (F:\Projects\Heimdall, HEAD): carries optional `primaryEmail` from OAuth identity into account create/update: src/app.ts:381,1048,1052,1078; src/backend-handoff.ts:8; src/oauth.ts:27; src/store/in-memory.ts:81. No SMTP/mailer found in the grep (head -8 only, not exhaustive) [U].
+- Forgejo on Yggdrasil: mailer disabled (see above).
+
+## Q1 Self-hosted outbound
+- Gmail sender guidelines (https://support.google.com/a/answer/81126), all senders: SPF or DKIM; valid forward+reverse DNS (PTR) on sending IPs; TLS; spam rate <0.3% (recommend <0.10%); RFC 5322. Bulk (>5,000/day): both SPF and DKIM, DMARC published (p=none ok), From aligned with SPF or DKIM domain, one-click unsubscribe (List-Unsubscribe + List-Unsubscribe-Post) for marketing/subscribed mail only. DKIM key >=1024, 2048 recommended. Volume here (tens-hundreds/month) is far below the 5,000/day bulk line, so only the all-senders rules apply by the page's wording.
+- Gmail rejection codes 4.7.29-4.7.31 for non-compliance [U] (secondary summary of the Google page).
+- Outlook.com high-volume sender requirements (5,000/day, SPF/DKIM/DMARC, reject action): fetch failed to return body; only title/keywords seen [U]. https://techcommunity.microsoft.com/blog/microsoftdefenderforoffice365blog/strengthening-email-ecosystem-outlook%E2%80%99s-new-requirements-for-high%E2%80%90volume-senders/4399730
+- Yahoo: not fetched; secondary sources say same 2024 requirements as Google [U] (https://help.close.com/docs/requirements-for-bulk-email-senders).
+- Netcup port 25: conflicting sources, no official Netcup page retrieved. serverkueche.de tutorial says new servers ship with SCP firewall policy "netcup Mail block" blocking outbound 25, 465, 587 (silent timeout), removable in SCP by deactivating the template (https://serverkueche.de/en/tutorials/netcup-firewall-setup/); netcup community forum thread (Aug 2026 per search summary) agrees default firewall blocks mail ports (https://forum.netcup.de/thread/22247-netcup-firewall-blockiert-smtp-ports-warum/); netcup.discount (third party) claims port 25 open by default (https://www.netcup.discount/en/guides/port-25-unblock). All [U]. Note this SCP firewall is separate from Yggdrasil's ufw.
+- PTR/rDNS on Netcup is set in SCP (per netcup.discount guide) [U].
+- IP reputation/warm-up/blocklists for VPS ranges: not researched beyond Mox README: "Large or cheap cloud providers often don't maintain good reputations or may block all outgoing SMTP"; new machines may have SMTP blocked initially, opened after cool-down or support contact (https://github.com/mjl-/mox).
+- Stacks:
+  - Mox (Go, MIT, Mechiel Lukkien, NLnet/EU funded; SMTP in/out, IMAP, webmail, SPF/DKIM/DMARC, DANE, MTA-STS, TLSRPT, ACME; `mox quickstart` prints DNS records; README recommends dedicated machine + DNSSEC resolver; smarthost via Transport in mox.conf + Routes in domains.conf; if smarthost add its IPs to SPF) https://github.com/mjl-/mox . 1,105 commits, 196 open issues at fetch.
+  - Stalwart (Rust, AGPL-3.0 + Enterprise SELv2, ~85% features AGPL; SMTP/IMAP/JMAP/CalDAV; DMARC/DKIM/SPF/ARC/DANE/MTA-STS; queues, routing rules; weekly community releases; only vouched contributors, bugfix/translation PRs) https://github.com/stalwartlabs/stalwart
+  - Maddy (Go, GPL-3.0; replaces Postfix+Dovecot+OpenDKIM etc.; IMAP "beta"; commit/release recency not shown in fetch; smarthost support not stated on page) https://github.com/foxcpp/maddy
+  - Postfix+OpenDKIM, Chasquid: not researched.
+- Unattended-operation failure modes: not found in sourced material beyond Mox README note on IP reputation. Stalwart fetch at stalw.art/docs redirected without content.
+
+## Q2 Transactional providers (pricing fetched from vendor pages 2026-10-30)
+- Postmark: Free 100 emails/mo, no overages, no expiry; no tier between 100 and 10,000/mo; Basic $15/mo for 10,000; inbound on Pro $16.50 and Platform $18 only; data residency not stated on pricing page; new accounts start on free plan, no approval text on page. https://postmarkapp.com/pricing
+- Amazon SES: $0.10/1,000 outbound + $0.12/GB attachments; no permanent free email quota on page (new-AWS-customer credits up to $200, 6 months); inbound $0.10/1,000 + $0.09/1,000 chunks; dedicated IP $24.95/mo. Sandbox/production-access text not on page [U]. https://aws.amazon.com/ses/pricing/ . EU regions exist (eu-west-1 etc.) [U not fetched].
+- Mailgun: Free $0, 100 emails/day, 1 domain, 1 inbound route, 1-day log retention; Basic $15/mo for 10,000, 5 inbound routes; "send through the US or the EU from a single account". https://www.mailgun.com/pricing/
+- Resend: Free 3,000/mo with 100/day cap, 3 domains; Pro $20/mo for 50,000; multi-region sending on all plans (EU not named on page); inbound on all plans via webhooks, counts toward quota. https://resend.com/pricing
+- Mailjet: Free 6,000/mo, 200/day; Starter $9/mo 8,000; EU hosting not stated on page; GDPR/DPA link present; inbound = "Parse API", limits not stated. https://www.mailjet.com/pricing/
+- Brevo: pricing page fetch gave no numbers. Search summaries: free 300/day, SMTP relay smtp-relay.brevo.com:587, Brevo branding on free plan mails, French company with EU data centres, paid tiers conflicting ($9/$25) [U]. https://www.brevo.com/en/bulk-email-service/ ; inbound parsing mentioned on page, details not seen.
+- Scaleway TEM (search summary of scaleway.com docs/pricing; direct fetch 403): EUR 0.25/1,000 pay-as-you-go, free 300/mo, billed per recipient; Scale plan 100K emails + dedicated IP ~EUR 80/mo (French site) [U]. Pages: https://scaleway.com/en/pricing/managed-services , https://www.scaleway.com/en/docs/transactional-email/reference-content/tem-capabilities-and-limits/ . Inbound: not found [U]. Scaleway is French (EU residency) [U].
+- Account suspension/approval behaviour for new senders, .NET SDK vs SMTP relay per provider, DPAs: not retrieved for any provider (all of these offer SMTP relay and REST API per general knowledge [U]).
+
+## Q3 Hybrid (self-hosted inbound + provider smarthost)
+- Mox documents the pattern directly (Transport/Routes smarthost, SPF include of relay IPs, caveat: relay may rewrite Message-ID or reject multiple DKIM signatures). https://github.com/mjl-/mox
+- Frequency of the pattern in practice: only generic search hits on "Smart host" (https://en.wikipedia.org/wiki/Smart_host); no prevalence data found.
+
+## Q5 Account-security prior art
+- OWASP Forgot Password Cheat Sheet (https://cheatsheetseries.owasp.org/cheatsheets/Forgot_Password_Cheat_Sheet.html): tokens from CSPRNG; single use and expire after an appropriate period (no number given); invalidate outstanding links after success; tie token to user; rate-limit requests per account; identical response and timing whether or not account exists; do not build URLs from Host header; HTTPS; Referrer-Policy no-referrer on the reset page; do not auto-login after reset; do not lock account on forgot attempts; page refers to Password Storage cheat sheet for storage (hashing not mandated on page).
+- Not researched: GitHub/Slack/Discord/Notion invite and recovery lifetimes, email as recovery factor for OAuth-only accounts, OWASP magic-link-specific guidance, NIST 800-63B out-of-band authenticator (10-minute lifetime is my recollection) [U].
+- Related local prior art: Loomio single-use email invite link, no expiry found [U] (Bifrost docs/research/customer-onboarding-prior-art.md:37).
+
+## Gaps
+Live DNS (MX/SPF/DMARC) not queried; Yggdrasil port 25 untested; Outlook/Yahoo primary pages not read; provider suspension policies, DPAs, .NET SDKs, EU-hosted extras (e.g. Mailjet/Brevo/Scaleway residency confirmation), account-security prior art mostly unresearched (tool budget).

+## Q1 Spec
+MSCs (all github.com/matrix-org/matrix-spec-proposals/pull/N):
+- 2812 [WIP] Role-based power/permissions (turt2live): OPEN, unmerged, last update 2025-08-12, labels needs-implementation, requires-room-version.
+- 4056 Role-Based Access Control (mk II) (turt2live, created 2023-09-15): OPEN, last update 2025-04-12. PR body is only a rendered link (branch travis/msc/rbac-pl); text not read [U].
+- 3949 Power Level Tags (ajbura): OPEN, update 2026-10-11, needs-implementation. Defines state event `m.room.power_level_tags`, state_key "", content = map of power-level integer -> {name, color (hex), icon{key emoji|mxc, info}}; its text says tags would show in timeline and member list. Implementation listed: Cinny. Text: raw.githubusercontent.com/ajbura/matrix-spec-proposals/power-level-tag/proposals/3949-power-level-tag.md
+- 4522 Username colors (nushea, created 2026-07-28): OPEN. `m.color_preference` {on_dark,on_light}: per-account in extended profile (MSC4133), per-room in `m.room.member` content, per-message in `m.per_message_profile`. Implementation: Sable PR 1526 (setting + rendering).
+- 4527 State event power levels (created 2026-08-09): OPEN. Impl links: complement#940, ruma#2640, Continuwuity PR 2393.
+- 3915 Owner power level (0-150): CLOSED unmerged 2026-01-18, label finished-final-comment-period.

+
+Space-wide power levels:
+- 2962 Managing power levels via Spaces (ara4n): OPEN, last update 2022-05-05. Template power_levels in parent space inherited by children (per search summary of its text [U]).
+- 3216 Synchronized access control for Spaces (joepie91): OPEN, 2022-05-05. Adds `m.space.power_levels`; comment: a non-spaces-aware client's edits get overwritten on next inherited change [U, search summary].
+- No merged MSC found giving space-wide power levels. Both are OPEN.
+
+Custom state events:
+- Spec: complete event MUST NOT exceed 65536 bytes (spec.matrix.org/latest/client-server-api/).
+- Per-event-type send level via `m.room.power_levels` `events` map, else `state_default` [spec knowledge, not re-fetched, U].
+- State arrives via /sync as room state; whether a client reads an unknown type is client-specific. Cinny reads `m.room.power_level_tags` (Q3).
+
+## Q2 Element Web
+- Releases: v1.12.33 (2026-10-27), v1.12.32 (2026-10-16), v1.12.31 (2026-10-13), with rc builds in between (gh api repos/element-hq/element-web/releases). Repo is a pnpm/nx monorepo: packages/{module-api, shared-components, shared-types, shared-utils, ...}, modules/{banner, restricted-guests, widget-lifecycle, widget-toggles}.
+- License: AGPL-3.0 (GitHub spdx); repo also contains LICENSE-GPL-3.0 and LICENSE-COMMERCIAL ("Licensees holding a valid commercial license with Element may use this software in accordance with the terms contained in a written agreement").
+- AGPL duties for a hosted modified fork: not sourced this pass [U]. (General knowledge: section 13 network-use source offer.)
+- config.json (docs/config.md): `default_theme`, custom themes, `branding`, `embedded_pages`, `setting_defaults`, `features` (labs), UI-feature toggles, and `modules` (array of URLs/paths dynamically imported at startup, ~lines 597-609). Doc: "doesn't support complete re-branding/private labeling".
+- Module API: `@element-hq/element-web-module-api` 2.3.0 (packages/module-api/package.json). Module = class with static `moduleApiVersion` semver and `load()`. Surfaces in packages/module-api/src/api/: auth, builtins, client, composer, config, custom-components, customisations, dialog, extras, i18n, navigation, profile, settings, stores, urlpreview, widget, widget-lifecycle, x509.
+  - custom-components.ts (@alpha, "Subject to change"): custom message renderers with render hints, including a hint documented as "Should the sender's profile be rendered for this event" (default true); room preview bar renderer. Overriding render means editing is unavailable.
+  - customisations.ts: `registerShouldShowComponent` only shows/hides listed UI components (invite, create room/space, directory, widgets, explore, room options).
+  - extras.ts (@alpha): space-panel item, room-header buttons.
+  - profile.ts: read-only profile of the logged-in user.
+  - No sender-name decorator or member-list hook found in the file listing; stores.ts, builtins.ts, client.ts not read in detail [U].
+- Theme details (custom theme JSON/CSS variables): not read [U].
+- Maintained-fork cost (merge pain, cadence of known forks): not gathered [U].
+
+## Q3 Other clients and prior art
+- Cinny (AGPL-3.0, pushed 2026-10-28): src/app/hooks/usePowerLevelTags.ts has DEFAULT_TAGS {9001 Goku, 150 Manager, 101 Founder, 100 Admin, 50 Moderator, 0 Member}, each with name+color; reads a state event (type in src/types/matrix/room.ts); src/app/hooks/useMemberPowerTag.ts resolves a member's tag from power level, with a room-creators tag, and applies `accessibleColor` per ThemeKind. This is the MSC3949 implementation.
+- Sable (AGPL-3.0; repo now "Sable-Legacy", v2 at git.sable.moe): implements MSC4522 colours (SableClient/Sable#1526, per MSC text).
+- Commet (AGPL-3.0, pushed 2026-10-29): room permissions settings page defines `MatrixRoomRoleEntry` {name, powerlevel} (commet/lib/ui/pages/settings/categories/room/permissions/matrix/matrix_room_permissions_page.dart). Timeline colour/badge display not checked [U].
+- FluffyChat, Nheko, SchildiChat: issue searches returned nothing; no evidence either way [U].
+- Rocket.Chat-on-Matrix, Conduit/Continuwuity communities, Polycule: not researched [U]. Continuwuity has an MSC4527 implementation PR (forgejo.ellis.link/continuwuation/continuwuity/pulls/2393).
+- mautrix-discord (github.com/mautrix/discord): stores Discord roles in a DB `role` table (dc_guild_id, dcid, name, icon, mentionable, managed, hoist, color, position, permissions), synced from GuildRoleCreate/Update/Delete (user.go:684-688, 978+; database/role.go). ROADMAP.md lists "Power level" and "Role permissions" unchecked. portal.go:1734-1739 uses room power levels only to gate @room mentions. No evidence found of writing Discord roles into Matrix state or power levels.
+
+## Q4 Body
+- Chat map: F:\Projects\gamecult-ops\docs\gamecult-chat-map.md. Element Web at chat.gamecult.org is static `root /srv/element-web/current` (symlink to /srv/element-web/releases/<version>), 404 until campaign cut C5 (lines 71, 101); runbooks/gamecult-chat-host-yggdrasil.md:6 says Element Web's release belongs to C5. No deployed Element release found in the docs. Homeserver matrix.gamecult.org -> Synapse 127.0.0.1:8834; federation and admin paths 404; apex /.well-known/matrix/client base_url https://matrix.gamecult.org (lines 93-102).
+- Synapse: ygg-verify probe ran matrixdotorg/synapse 1.163.0 on postgres:16 (chat map line 27, P5). Upstream latest Synapse v1.164.1 (2026-10-28), MAS v1.28.0 (2026-10-27). Deployed versions on Yggdrasil not checked (no ssh) [U].
+- Idunn targets `synapse`, `matrix-auth`; C3 `synapse-mas-under-idunn` packages them.
+- Bifrost origin/main docs/oidc-issuer.md: OpenIddict 7.7.1; scopes `openid profile`; claims only `sub`, `preferred_username` (never changes), `name`; "No e-mail, no Heimdall id, no GitHub id, and no membership detail leaves Bifrost". MAS is the OIDC client.
+- Bifrost role code: only membership roles in its own DB (`MemberRole` StandardMember|Producer|Maintainer|LedgerReviewer|PlatformAdmin, RoleAssignment; src/Bifrost.Web/Data/BifrostDbContext.cs:113-114; docs/research/customer-onboarding-body-facts.md:16). Grep of origin/main docs and src for power_level / m.room.power found nothing. docs/bridge.md:199: Personas speak through `tools/persona-matrix-mouth.mjs` with per-persona Matrix access tokens (the only Matrix writer found).

+// The Matrix ear and mouth of every Persona. One process: one account (token) and
+// one /sync loop per Persona, one CultNet endpoint for all of them.
+//
+// Ear: /sync the configured rooms (and the account's direct rooms); every message
+// from another sender becomes a delivery kept in memory, carrying its sender id,
+// its m.mentions user ids and whether the room is a DM. The /sync position
+// (next_batch) is persisted only when an ack covers it, so a restart before the
+// ack re-delivers instead of losing. Reading wakes nothing: the heartbeat polls
+// with a non-consuming chat_pending_request and decides who runs.
+// Mouth: a send request becomes one PUT with txnId = request_id (a retry is idempotent), and a room
+// is joined, only while that Persona's brake is released. A v2 send carries the basis of her turn (the
+// newest room event she saw): inside the room gate, one step per room across every Persona, the mouth
+// reads the room's head from Matrix and answers RoomMoved, naming the messages that moved it, instead
+// of the PUT. A v1 send, and a v2 send with no basis, are not checked; both still pass through the gate.
+//
+// Context: Matrix is the record. A delivery's `context` is read from the homeserver when the delivery
+// is built (GET /messages, or the thread's relations for a threaded message), as this Persona's
+// account, and holds m.room.message events from everyone, her own included, oldest first, ending
+// just before the delivered event. Nothing about a room's past is kept in this process, so a restart
+// loses none of it. A failed fetch gives empty context and a log line; the delivery still goes out.
+//
+// Each Matrix access token is read here, from its own systemd credential, and
+// nowhere else. It is never put in a document, an environment passed to a child,
+// or a log, and it is only ever presented in its own Persona's Authorization header.
+//
+// Everything outside this process is a port (fetch, state, brake, clock), so the
+// core runs against a fake homeserver with no CultLib and no daemon.
