* feat(plugin): add MiniMax-H3 /v2 video generation to the hailuo task plugin
MiniMax-H3 speaks a different contract from the other Hailuo models, so the
hailuo task plugin now branches on the upstream model instead of adding a Go
adaptor:
- submit builds /v2/video_generation with a multimodal `content` array
(text, first/last frame images, reference video/audio, or a full
`metadata.content` passthrough), an explicit `ratio`, and 768P/2K
resolutions; `metadata.callback_url` and `metadata.aigc_watermark` pass
through
- query uses /v2/query/video_generation/{task_id} and parses the
`{"task": {...}}` envelope, falling back to the /v1 shapes for every other
model
- the /v2 result is a public CDN URL, so its artifact is proxied
credentialless instead of through /v1/files/download
- request bounds (duration 4-15, resolution 768P/2K, ratio whitelist, at most
2 frame images and 9/3/3 reference images/videos/audios) are enforced while
the request body is built, which the host runs during validation, so an
out-of-range duration is rejected with a 400 before it can become a billing
multiplier
- duration and resolution are reported as usage facts only. Like the rest of
this plugin, extractUsage returns no billing ratios, so per-call pricing is
flat and 2K/duration pricing is expressed through the model's tiered billing
expression over those facts.
Query hooks are driver hooks and are documented to receive `ctx.model` and
`ctx.upstreamModel`, but polling has no relay info and never populated them.
The polling and realtime-fetch call sites now carry the persisted task model
properties and the plugin adaptor maps them onto the query context, with
`upstreamModel` falling back to the origin name for tasks submitted without a
channel mapping.
* fix(plugin): validate Hailuo H3 requests and errors
Channel model_mapping keys exposed in a channel's model list now act as
first-class aliases for task-plugin models across the whole line:
- Derived alias view (model/task_model_alias.go): built from enabled
channels' model_mapping, chain-following with cycle detection, declared
names always win, cross-plugin conflicts dropped. Rebuilt on channel
cache refresh, registry generation change, and a 60s TTL.
- Request path: PinTaskPluginEndpoint resolves declared-name case folds
and mapping aliases before endpoint lookup (never rewriting the body
until the endpoint is claimed), pins with MappedModel, and the decode
contract accepts alias echoes without loosening model ownership for
normal pins. Legacy /v1/tasks submit folds case variants the same way.
Fixes aliases on POST /v1/responses silently falling through to the
main relay against task channels.
- Mapping order: ModelMappedHelper now runs before the plugin submit
hook builds and caches the upstream body, so channel model_mapping
actually reaches the upstream request. Plugins receive the mapped
name as ctx.upstreamModel in both decode and submit contexts.
- Billing: identity stays the origin name; when the alias has no tiered
expression, the selected channel's mapping tail expression applies.
Pricing page and billing-expr smoke tests resolve aliases to the
owning plugin's usage schema.
- Case folding: ASCII-only fold with exact-match priority; same-plugin
and cross-plugin fold collisions rejected at registration.
- Plugins: model-keyed rate tables, req_key derivation, and combo
validation in doubao/kling/jimeng/hailuo/vidu/sunoapi now key on
ctx.upstreamModel || ctx.model; render/echo paths keep ctx.model.
