Final milestone of docs/plans/llm-fallback-aliases.md. Every backend
caller now requests models via the `mana/<class>` alias system instead
of hardcoded `ollama/...` strings. mana-llm resolves aliases through
`services/mana-llm/aliases.yaml` with health-aware fallback (M3) and
emits resolved-model + fallback metrics (M4).
SSOT moved to `packages/shared-ai/src/llm-aliases.ts` so apps/api,
apps/mana/apps/web, and services/mana-ai all import the same
`MANA_LLM` constant via the existing `@mana/shared-ai` workspace
dependency. Three additional sites (memoro-server, mana-events,
mana-research) inline the alias string with a SSOT comment because
they don't pull @mana/shared-ai today.
Migrated 14 sites across 10 files:
- apps/api: writing(LONG_FORM), comic(STRUCTURED), context(FAST_TEXT),
food(VISION), plants(VISION), research orchestrator (3 tiers
collapsed to STRUCTURED+FAST_TEXT/LONG_FORM)
- apps/mana/apps/web: voice/parse-task + parse-habit (STRUCTURED)
- services/mana-ai: planner llm-client + tick.ts (REASONING)
- services/mana-events: website-extractor (STRUCTURED, inlined)
- services/mana-research: mana-llm client (FAST_TEXT, inlined)
- apps/memoro/apps/server: ai.ts (FAST_TEXT, inlined)
Legacy env-vars removed: WRITING_MODEL, COMIC_STORYBOARD_MODEL,
VISION_MODEL, MANA_LLM_DEFAULT_MODEL. The chain in aliases.yaml is
now the single tuning surface; SIGHUP reloads it without redeploys.
New `scripts/validate-llm-strings.mjs` regex-scans 2538 files for
hardcoded `<provider>/<model>` strings and fails the build if any
land outside the SSOT or the explicitly-allowed paths (image-gen
modules, model-inspector code, this validator itself, the registry).
Wired into `validate:all` next to the i18n + theme validators.
Verified: `pnpm validate:llm-strings` clean, `pnpm --filter @mana/api
type-check` clean, `pnpm --filter @mana/ai-service type-check`
clean. Web type-check has 2 pre-existing errors in
SettingsSidebar.svelte (i18n MessageFormatter type drift, last
touched in 988c17a67 — unrelated to this work).

Server:
- New llmText() helper in apps/api/src/lib/llm.ts for plain-text
(non-streaming) completions with token-usage reporting.
- POST /api/v1/writing/generations (Hono + requireTier('beta'))
accepts system+user prompts, forwards to mana-llm (default model
ollama/gemma3:4b), returns raw output + model + tokenUsage. The
endpoint is stateless — draft/version bookkeeping is entirely
client-side so the same route serves refinement calls later.
Client:
- writing/api.ts — Bearer-authed fetch client (follows the food/
news-research pattern).
- writing/utils/prompt-builder.ts — pure builder turning a briefing
(+ optional style preset / extracted principles) into a system+user
pair. Forbids preamble / sign-off / meta commentary so the output is
ready to paste into a version.
- writing/stores/generations.svelte.ts — orchestrates the full flow:
queued → running → call → new LocalDraftVersion → pointer flip →
succeeded. On failure leaves the current version untouched with the
error on the generation record. Emits WritingDraftGenerationStarted /
WritingDraftVersionCreated / WritingDraftGenerationFailed events.
UI:
- Generate button in DetailView.svelte (label flips "Generate" / "Neu
generieren" based on whether the draft already has content).
- GenerationStatus.svelte strip surfaces queued / running / failed with
model + duration badges; succeeded generations auto-disappear because
the new version is already live via the currentVersionId pointer.
M3 is synchronous and non-streaming by design. M7 adds mission-based
long-form with streaming + outline stage + reference injection. M6 will
reuse the same /generations endpoint for selection-refinement prompts.
