§3 "/api/usage 全量泄露所有 key 时序"). Previously, any caller authenticated as
admin received the full per-key usage byKey + recent + timeline block, which
means a brief admin-token compromise exposes every household member's request
volume, timing, and which-model — metadata, but sensitive metadata.
This is a deliberate breaking change for least-privilege.
Behavior matrix (post-change):
Caller | Default scope | ?all=true
----------------------------------------|-------------------|---------------------
anonymous (PROXY_ANONYMOUS_KEY) | own ("anonymous") | ignored (still own)
authenticated non-admin key | own (key.name) | ignored (still own)
admin (no flag) | own ("admin") | n/a
admin with ?all=true | n/a | full byKey/recent
localhost-no-token / "local" | own ("local") | full (isAdmin=true)
Response shape is unchanged except for an additional advisory `scope` object
(`{self, all}`); existing fields keep their structure so dashboards and scripts
continue to parse cleanly — they just see less data unless they opt in.
Audit-friendly addition: when admin opts into `?all=true`, the server now
emits `logEvent("info", "admin_usage_full_scope", { caller, ip })` so every
privilege-escalation moment is recorded.
Backward-compat warning for admin scripts:
existing cron jobs / scripts that call `/api/usage` to inventory all keys must
add `?all=true` after this change. Default-self is the new safe behavior.
Dashboard (dashboard.html): adds a "Show all keys" checkbox in the Usage by
Key section. Hidden by default; revealed only when refreshKeys() succeeds
(same admin gate as the keys-management section). Toggle state persists in
localStorage as `ocp_usage_show_all`.
cli.js citation
---------------
This is OCP-internal admin API behavior — there is no `cli.js` operation to
cite. ALIGNMENT.md Rule 2 (the rule that limits OCP to operations that exist
in `cli.js`) does not constrain access-control rules for the OCP server's
own admin endpoints.
Smoke test (isolated test server on :3489, prod :3478 untouched):
- node --check server.mjs SYNTAX_OK
- npm test 43/43 passed
- alignment.yml blacklist grep BLACKLIST_CLEAR
- LAN scope matrix alice/bob own only; alice ?all=true denied;
anon ?all=true denied; admin all=true full +
audit log emitted
Iron Rule 10
------------
Author cannot self-approve. A separate fresh-context reviewer must read the
diff and confirm the cli.js-not-applicable statement is correct before merge.

- Support ?token=xxx query parameter for dashboard auth (enables
headless browser screenshots and direct links)
- Token is saved to localStorage and URL is cleaned up
- Fix pathname matching to handle query parameters in URL
- Replace html2canvas screenshot with Playwright (accurate colors)
