Summary

• POST /agents/import/preview parses pasted YAML, JSON or an lousho.agent-bundle (1 MB cap), upgrades v1 specs via upgradeSpec + agentSpecV2Schema, and answers an ImportPreview: format, spec, normalised bundle labels (L13 normalizeLabels, LabelError → 400 LOUSHO_IMPORT_INVALID), suggestedId, name clash, per-mode resolvedId, computeRequirements rows, bundle prompt list and warnings (Upgraded from spec v1., per-prompt daemon notice, newer-Studio bundle refusal).
• POST /agents/import writes under withAgentLock(resolvedId): new/copy mint a disabled agent (enabled: false, createdFrom import/copy) with a create/import version; replace keeps the target's enable/publish/disable state, sets labels only for bundle imports, baselines external edits first and captures an update/import version the store skips when content is identical. Bundle prompts are POSTed to the observe daemon best-effort (failures ignored); agent.changed reason import is published.
• server/lifecycle/agentIds.ts: slugifyAgentId (delegates to the create route's slugAgentId), resolveFreshId, resolveNextCopyId — the copy resolver is shared with L10. agentIdTaken is exported from storage/agentIds.ts as the exists predicate.
• server/agentRecord.ts: the AgentRecord assembler extracted from agentRoutes (which now aliases it) so import answers the same record shape GET /agents/:id returns.
• Routes register before registerAgentRoutes so import is never an agent id; runtimeClient gains previewImport/importAgent for L08b's sheet.

Test plan

• agentIds.test.ts (14): slug cases, copy/fresh sequences, 1000-exhaustion
• importParse.test.ts (10): yaml/json/bundle, newer bundle, empty, >1 MB, invalid JSON/YAML, schema error path+details
• importRoutes.test.ts (12): preview fields, clash + per-mode resolved ids, new/copy/replace writes (spec file, meta, version lines), replace 404/missing target, prompt POST stubbed + failure ignored, agent.changed published, route ordering
• Full server suite: 127 files / 1554 tests green; full client suite: 236 files / 3981 tests green
• Server + client typechecks clean; fallow dead-code clean; fallow dupes clean (pre-existing L11b advisory only); lint clean except pre-existing steerGate.ts:80
• fallow health not runnable locally: root test:coverage cannot emit coverage-final.json because 101 pre-existing EPERM: symlink tests fail on this Windows box (unrelated env issue); dead-code/dupes gates pass
