B0 — sprout-core/src/mesh_llm.rs (new): MeshLlmOffer envelope, the
content of a kind:31990 event. Schema versioned (v: u32), with
deny_unknown_fields at the top level and a freeform 'extra' Value
escape hatch. ResourceCaps + ModelOffer sub-structs. d_tag charset is
limited to [A-Za-z0-9_-] (NIP-33 stability). 9 unit tests covering
round-trip JSON, optional caps, unknown-field rejection, d_tag
validation, is_publishable rule set.
B2 — desktop/src-tauri/src/mesh_llm/endpoint.rs: persists the iroh
endpoint keypair to {app_data_dir}/mesh_iroh.key as 32 hex bytes.
Atomic write via tempfile.persist; corrupt files quarantined to
.bad.{epoch} (same pattern as identity.key). 2 unit tests.
Design note in the module doc: we deliberately do NOT derive the
iroh key from the Nostr key, because that would couple key rotation
(rotating the Nostr key would silently break active offers) and
invent a new key-custody convention. Separate file, same Tauri
sandbox.
B3 — desktop/src-tauri/src/mesh_llm/nip98.rs: build_nip98_bearer(keys,
iroh_relay_public_url) signs a kind:27235 event with the user's Nostr
key over the canonical relay URL (sprout_auth::nip98_canonical_url
with path '/relay'), base64-encodes the event JSON. This is the exact
token the relay's iroh_relay::verify_bearer decodes + verifies.
3 unit tests.
B-offer prefs — desktop/src-tauri/src/mesh_llm/offer.rs: persisted
ComputeSharingPrefs (the avatar-menu sliders). Default is disabled,
1 concurrent consumer cap. build_offer() returns None when disabled
so callers know to *delete* any prior offer rather than re-publish.
JSON round-trip + helper tests, 4 tests.
Workspace deps added:
- desktop pulls sprout-auth (for the canonical URL helper, nostr-free
at the API surface so the 0.36/0.37 nostr split doesn't matter).
- desktop pulls iroh-base = =1.0.0-rc.0 with the 'key' feature for
SecretKey/PublicKey/EndpointId.
- desktop pulls thiserror = '2'.
Tests: 9 desktop mesh_llm tests pass + 9 sprout-core mesh_llm tests
pass. Workspace clippy + fmt clean (relay side; desktop has expected
dead_code warnings until B4-B6 wire these in).
Note: desktop crate requires sidecar binary stubs in
desktop/src-tauri/binaries/ to typecheck; created via the existing
'just _ensure-sidecar-stubs' helper.
