dashscope-cn: models poll fails on "unreadable RMB token quote: 原价2元 （限时2.5折）" #603

What

Once #601 deployed (2026-11-09 ~02:10 UTC), the dashscope-cn models poll got past the cache-hit cell and now throws on the next Beijing price cell:

dashscope-cn: unreadable RMB token quote: 原价2元 （限时2.5折）

PostHog ingest_failed, job models-poll, first at 2026-11-09 02:17 UTC. The cell is deterministic, so every poll fails and no dashscope-cn rows update.

Meaning

原价2元 （限时2.5折） = list price 2元 per million tokens, limited-time 2.5折 (pay 25% of list, i.e. 0.5元).

Fix

• Find the row(s) and whether the page states the promo end date.
• Store the billed price, per the no-pricing-fallbacks rule: the discounted rate while the promo runs. If the page states no end date, follow the FAL promo precedent (FAL pricing extract: model call returns "500 Model execution failed" since the Sonnet 5.5 gateway switch (#551) #552) for how an open-ended promo is recorded; don't invent an end date.
• Any other promo wording still throws (fail-closed).
• Test with the exact cell text.
