1func AddMember(cur realm, addr address, roles string)

source

AddMember adds an address with specified roles. Only the owner can call this. roles is a comma-separated list (e.g., "admin,dev" or "member").

1func CreateChannel(cur realm, name, description string, ctype string)

source

CreateChannel adds a new channel. Only the owner (admin) can create channels.

1func DeleteReply(cur realm, channel string, threadID, replyID uint64)

source

DeleteReply lets the reply's author delete it. Caller must be a member and the original author. The reply node is hard-removed (B2 state-shrink) and a slot is freed under MaxRepliesPerThread (B1).

1func DeleteThread(cur realm, channel string, threadID uint64)

source

DeleteThread soft-deletes a thread (marks as deleted). Caller must be a member and the original author.

1func EditThread(cur realm, channel string, threadID uint64, newBody string)

source

EditThread allows the original author to edit their thread. Caller must be a member.

1func FlagThread(cur realm, channel string, threadID uint64)

source

FlagThread flags a thread for moderation review. After FlagThreshold flags, the thread is auto-hidden. Caller must be a member (any role) to flag content.

1func GetMemberRoles(addr address) string

source

GetMemberRoles returns the roles for a member (comma-separated) or empty string.

1func GetTombstoneCount(channel string) int

source

GetTombstoneCount returns how many soft-deleted threads in a channel are still awaiting hard-GC (read-only; lets ops/indexers decide when to call SweepTombstones).

1func IsMember(addr address) bool

source

IsMember returns whether an address is a member.

1func IsPaused() bool

source

1func PauseRealm(cur realm)

source

1func PostReply(cur realm, channel string, threadID uint64, body string)

source

PostReply adds a reply to a thread. Caller must be a member with a role listed in the channel's WriteRoles.

1func PostThread(cur realm, channel, title, body string) uint64

source

PostThread creates a new thread in a channel. Caller must be a member with a role listed in the channel's WriteRoles.

1func PurgeNonMembers(cur realm, keepAddresses string)

source

PurgeNonMembers removes all members not in the provided comma-separated list. The owner is never purged.

1func RemoveMember(cur realm, addr address)

source

RemoveMember removes an address from the membership. Only the owner can call this.

1func RemoveReply(cur realm, channel string, threadID, replyID uint64)

source

RemoveReply permanently removes a reply (moderation — admin role only). Hard- removes the node like DeleteReply, bounding renderThread (B1) + reclaiming storage (B2).

1func RemoveThread(cur realm, channel string, threadID uint64)

source

RemoveThread permanently removes a thread (moderation action — admin role only).

1func Render(path string) string

source

1func SweepTombstones(cur realm, channel string, limit int) int

source

SweepTombstones hard-removes up to `limit` soft-deleted threads in a channel (and all of their remaining reply state), reclaiming AVL storage so that post+delete spam can no longer accrete permanent state (B2).

Permissionless GC by design: anyone may call it. Released storage deposits go to the calling tx per the chain's deposit policy (an explicit caller bounty); on restricted-denom chains (e.g. test12/test13 `restricted_denoms=["ugnot"]`) they route to the StorageFeeCollector instead — so this is a state-shrink/ hygiene primitive, not a user-refund path (see plan B2 / Q11).

Bounded + idempotent: each soft-deleted thread holds at most MaxRepliesPerThread reply nodes, so keep `limit` small (1–5) to stay well within block gas; re-running drains the next batch and stops at 0. Returns the number of threads swept.

1func SyncMembers(cur realm, addresses string, rolesList string)

source

SyncMembers allows the owner to batch-sync membership from the DAO. addresses and rolesList are comma-separated, with roles pipe-delimited per address. Example: SyncMembers("g1a,g1b", "admin,dev|member")

1func TransferOwnership(cur realm, newOwner address)

source

TransferOwnership transfers realm ownership to a new address. Only the current owner can call this. The new owner gets "admin" added to their existing roles (not overwritten). The old owner is demoted from "admin" to "member".

1func UnhideThread(cur realm, channel string, threadID uint64)

source

UnhideThread allows the owner or an admin to clear flags and un-hide a thread.

1func UnpauseRealm(cur realm)

source

1func UpdateMemberRoles(cur realm, addr address, newRoles string)

source

UpdateMemberRoles updates the roles for an existing member. Only the owner can call this.
