* fix(api): stop the 2000-token safety buffer from inflating usage.prompt_tokens in the client response (#8331)
* fix(sse): scope #8331's usage-buffer fix around Claude-Code-compatible providers
The #8331 fix correctly stopped folding the 2000-token context-window safety
margin into client-visible prompt_tokens/input_tokens/total_tokens for normal
API metering clients. But it also silently changed the response shape for
Claude-Code-compatible providers, whose own context accounting reads the
buffered number straight out of usage — regressing
tests/unit/cc-compatible-provider.test.ts (expected 2007, got 7).
Fold the computed context_budget_* fields back into the visible usage fields
for that one path only (applyClientUsageBuffer's new
preserveContextBudgetInVisibleUsage option, gated on the existing
isClaudeCodeCompatible flag in chatCore.ts). Every other caller keeps the
real, unbuffered #8331 numbers.
* fix(notion-web): use real picker labels as primary model ids
Catalog /v1/models now surfaces web-picker names (fable-5, gpt-5.6-sol)
instead of Notion food codenames (acai-budino-high, orange-mousse).
Food codenames stay internal via notionCodename + resolveNotionCodename
for runInferenceTranscript. Legacy codename requests still work; responses
echo the client-facing id.
Also points discovery/inference at app.notion.com (same host as the AI picker).
Follow-up to #7696.
* fix(notion-web): explain plan-locked models like Fable 5
Notion returns Fable 5 (acai-budino-high) with isDisabled=true and
disabledReason=business_or_enterprise_plan_required. Keep it out of the
enabled catalog (requests would fail) but surface a discovery warning so
operators know why it is missing. Also warn when space_id is resolved via
getSpaces instead of the cookie.
* feat(notion-web): auto-detect workspace without pasting space_id
Operators only need the raw token_v2 value. When space_id is omitted:
- getSpaces loads all workspaces (browser-like headers + user id)
- each workspace is probed via getAvailableModels
- the richest AI catalog wins
Also softens auth hints so they no longer demand a cookie blob with =.
* fix(notion-web): pick Business workspace so Fable 5 is listed
Probe ALL workspaces instead of early-exiting on the first catalog with
>=8 models. Prefer spaces where Fable is enabled over personal spaces
where Notion returns isDisabled=business_or_enterprise_plan_required.
Cache the chosen spaceId for inference when cookie has no space_id.
* fix(notion-web): working inference + honest token estimates
- runInferenceTranscript: createThread+threadId, config/context/user
transcript, space/user headers (fixes ValidationError 400)
- Parse modern NDJSON patch/record-map; strip lang tags
- Estimate usage from text (Notion has no metering); mark estimated
- Treat all-zero usage as missing; skip USAGE_TOKEN_BUFFER on estimated
- Keep estimated flag through response sanitizer (was stripped -> flat 2000)
Verified live: fable-5/gpt-5.6-sol chat 200; usage 7 / 65 not constant 2000.
* refactor(notion-web): extract helpers to keep discoverNotionWebModels/execute under the complexity cap
