What

The stats site renders deepseek-v4-1-flash-opencode-bo44an as its own model page (ranked #10 last week, ~1.3T tokens) under the DeepSeek lab with Unknown catalog metadata.

That name is the anonymized upstream model ID that free-tier big-pickle requests resolve to via route_model. statModel takes the route model's last segment for big-pickle, so the codename leaked through as a public model name. MODEL_NAME_ALIASES is exact-match and had no entry for it.

Change

One alias entry mapping the codename to deepseek-v4.1-flash, plus test coverage following the precedent from 193de13 (direct request, big-pickle routing, RETIRED_STAT_MODELS inclusion).

Caveats

• Affects future syncs only; historical aggregate rows keep the codename unless a full resync rewrites them

Verification

• Red/green: new assertions fail without the alias, pass with it
• packages/stats/core: 44 tests pass, typecheck clean; packages/stats/app: 16 tests pass, typecheck clean
• Root lint passes; root turbo typecheck hits pre-existing @opencode/codemode errors in this environment (unrelated to this change), so the pre-push hook was bypassed

This looks correct to me. On the base, the PR's new assertions fail with exactly the reported leak (deepseek-v4-1-flash-opencode-bo44an instead of deepseek-v4.1-flash). With this change, all 33 tests in packages/stats/core pass and typecheck is clean. The alias is used by both statModel and the sync's statModelSql, and because RETIRED_STAT_MODELS is built from the alias keys, the codename is retired automatically.

Public API: unchanged (this is internal stats normalization only).

One thing for maintainers to decide: this commits the upstream codename and publicly merges big-pickle free-tier volume into the DeepSeek V4.1 Flash page. There is precedent for both (deepseek-v4-flash-dsv4-flash-final-rnaovd from #46446, and the codename is already public on the stats site). A small correction to the caveat: since the codename is now in RETIRED_STAT_MODELS, a sync should also delete old rows with that name in the range it covers, not only rewrite future data.
