Module provider_limits 

Provider usage limits as the provider itself shows them, read ONLY from PTY screens: the node’s limit heartbeat (crate::limit_heartbeat: one light service PTY per signed-in provider account) and any node PTY session that happens to show the screen.

• claude: /usage (and /status) — “Current session” = 5h window, “Current week” = 7d window, the plan from “Claude Max/Pro/Team/Enterprise”.
• codex: /status — its “5h limit” and “Weekly limit” lines.

Nothing is estimated, and no other source is read: no session logs or rollouts, no provider error text (that only notifies the operator), never tokens, OAuth or auth.json. Every entry keeps its source and observed_at_ms.

Structs

ProviderLimits

RawReading

A provider’s own limit line, kept as it was shown (providers say % used or % left).

Window

Functions

changed

codex_reset_ms

A codex reset as shown on its screen: resets HH:MM (the next such time) or resets HH:MM on D Mon (that day; next year when already past). The screen gives no zone, so it is the node’s local time (now’s offset).

collect

Everything seen on screens now.

fresh_5h_used

The 5h window usage of provider if a reading at most max_age_ms old is known (any source).

now_ms

observe_screen

Called from the frame publisher with every scanned session screen.

observe_screen_as

Remember a limit screen under source (screen or heartbeat). True when it was one.

parse_claude_screen

Parse a claude /usage (or /status) screen. None when it shows neither.

parse_codex_status

Parse a codex /status screen: the 5h limit / Weekly limit lines (N% used, or N% left), and the reset in parentheses. Nothing else on the screen is kept (it also shows the account’s email). None when it shows no limit line.

parse_screen

Parse screen as provider’s limit screen.

reading

The percent on line and what it means. left also covers remaining.

window_from

A window from a raw reading: used and remaining both derived from it; unknown keeps both unset (routing never guesses which way a bare percent goes).
