Validate the envelope of a kind:30175 persona event. Enforces: exactly one `d` tag with a non-empty value matching the slug grammar `^[a-z0-9][a-z0-9

Sign `build_set_event` output with a fresh key and return the event for tag inspection. `now` and signing key are local to the test; nothing about the

Build a git status event (kind:1630/1631/1632/1633, NIP-34). `content` is optional markdown context for the status change.

Build a stream message (kind 9). - `channel_id`: target channel UUID - `content`: message text (max 64 KiB) - `thread_ref`: optional NIP-10 reply con

Build a git repository announcement event (kind:30617, NIP-34). Creates or updates a repository. The `repo_id` is the unique identifier (d-tag) — mus

Serialize to canonical bytes suitable for `put_manifest`. Sorts `packs` defensively (writer is responsible for keeping them sorted, but a misuse shou

Convert a NIP-29 kind:39000 channel metadata event to [`ChannelInfo`]. Optionally merges with a kind:40901 channel summary sidecar event for `member_

Classify a `send()` failure into a stable, URL-free error string. The returned string always starts with `"relay unreachable:"` so the frontend conne

Normalizes and validates a relay-supplied branch name. Strips a `refs/heads/` prefix, then rejects anything outside a conservative character allowlist

Compute a stable SHA-256 fingerprint for a set of participant pubkeys. Pubkeys are sorted lexicographically before hashing so that the same set of pa

(Target) User confirmed the SAS codes match. Transitions to [`SessionState::Transferring`] so payloads can be received.

Build observer context values from optional channel/session/turn IDs.

Schedule post-commit delivery/side effects for a stored event. This intentionally returns after only the bounded audit enqueue has completed: NIP-01

Extract channel UUID from `h` tag (NIP-29 group ID).

Returns `true` if the event matches any of the provided NIP-01 filters.

Check if an object exists. Returns false on 404.

Insert a workflow under `community` with a caller-chosen `id` and `channel_id`, so two communities can be given the *same* workflow UUID and channel U

Build a minimal signed Event with the given kind and tags. The pubkey will be randomly generated — sufficient for tag extraction tests.

Copy the [`LEGACY_NEST_KNOWLEDGE`] entries from `legacy` to `current`. Each entry is copied independently with its own log-and-continue, so a failure

Parse a NIP-OA `auth` tag JSON string into a [`Tag`] without verifying the signature. Validates structure only: - Exactly 4 elements - First element

The canonical pointer key for a repo: `repos/<community>/<owner>/<repo>/pointer`. Single source of truth shared by `cas_publish` (write side) and `hy

POST to an OpenAI-family endpoint. For OpenAI-compat this is just `{base_url}{path}` with the body untouched. For Databricks the URL becomes `{base_ur

Prepare `text` for TTS synthesis. Applies in order: 1. Fenced code blocks → "code block omitted" 2. Inline code → bare content (backticks stripped) 3

Read content from a string value or stdin if the value is "-".

Returns the relay HTTP API base URL, checking the workspace override first. Precedence: workspace override > env vars > build-time vars > default.

Split `"provider:model-id"` into `(Some("provider"), "model-id")`. If there is no colon, returns `(None, full_string)`.

Update a workflow run's status.

Validate and deduplicate allowlist entries: each must be exactly 64 hex chars.

Validate that a URL is a legitimate relay media URL. Ensures: - URL scheme is `https` (or `http` for localhost dev) - URL origin matches the relay ba

Helper: write a `personas.json` directly in `base_dir` (the migration reads `base_dir/personas.json`, where `base_dir` is the `agents` dir).

Assert the connection is closed (stream ends) within 2 seconds.
