finding(app-shell): AiChatPage's publicShareBase is a third hand-rolled console-mount resolution — correct today, drift risk under the one-resolver rule

[yinlianghui]

Measured during #4472 (PR #4480's copy census). Observation-class: no user-visible defect today; no fix proposed here.

What

packages/app-shell/src/console/ai/AiChatPage.tsx:986 builds publicShareBase by reading the injected base-href tag itself and assembling ${origin}/_console/s — a third, independent implementation of the console-mount resolution that resolveConsoleUrl / resolveRootUrl (packages/app-shell/src/console/organizations/resolveHomeUrl.ts) already centralize.

Measured in the #4472 worktree: its output is correct for the deployment shapes tested — this is not #4472's defect (that one rebuilt from BASE_URL and produced the trailing-dot host).

Why it is worth recording

#4472 just deleted two local URL builders on the one-resolver principle; this is the surviving sibling. A correct-today duplicate of a centralized mechanism is exactly the shape that drifts: the next change to mount semantics (new deployment shape, base-href format change) updates the helper and misses the copy. Folding it into resolveConsoleUrl (the /s public-share path may need a parameter or a sibling helper — measure at fix time) removes the mechanism duplication.

Also for the record, from the same census: apps/console/src/utils/consoleBase.ts reads BASE_URL deliberately, never concatenates an origin, and is documented + tested — ruled not-in-family. The API-base display sites (ObjectApiPanel etc.) are not under the console mount — not in family.

Repo-wide test trap recorded in PR #4480 (relevant to whoever fixes this)

vi.stubEnv('BASE_URL', …) silently does nothing against the (import.meta as any).env?.BASE_URL spelling — Vite inlines bare import.meta.env at transform time, so such a test is permanently green. Write pins against the injected base-href mechanism instead.

Filed unassigned for triage.

Concentrated finding round (unified triage seat, 2026-08-17): promoted to pm:queue, type Task. The one-resolver rule is an established invariant here (#4472 deleted two siblings on it); this is the surviving third copy, and folding it in is a small drift-elimination with the census already done. Scope: route AiChatPage's publicShareBase through resolveConsoleUrl/a /s sibling helper — measure the parameter shape at fix time, per the card. Heed the recorded test trap: pin against the injected base-href mechanism, not vi.stubEnv('BASE_URL', …). S / sonnet–opus.

Dispatching on triage's ruled scope: route AiChatPage's publicShareBase through resolveConsoleUrl / a /s sibling helper, measuring the parameter shape at fix time. Carrying triage's recorded test trap into the brief — pin against the injected base-href mechanism, not vi.stubEnv('BASE_URL', …).
