[Desktop][macOS] 7-day usage remaining jumped from 48% to 23% after context/memory feature change

What issue are you seeing?

The Codex Desktop 7-day usage indicator appeared to drop instantly from 48% remaining to 23% remaining, despite very little intentional use that day.

Local session telemetry shows this is the primary 7-day rate limit, not the model context-window indicator:

• Earlier record: used_percent: 52.0 (48% remaining)
• Current record: used_percent: 77.0 (23% remaining)
• window_minutes: 10080
• Model context window is separately reported as 258,400 tokens

The first token_count event in a new diagnostic task already reported used_percent: 77.0, before its diagnostic tool calls. Therefore the apparent 25-point drop was not caused solely by that task. It looks like stale UI state being refreshed all at once, delayed server-side accounting, or incorrect attribution.

A context/memory/window-capture-related option had been enabled the previous day. Relevant observations:

• Later session metadata records show memory_mode: enabled.
• The currently persisted auto-context setting reports disabled.
• The affected session record does not contain actual window-context, screen-capture, OCR, or image input items.
• New turns do contain a large automatically injected payload, including plugin metadata, project instructions, skill metadata, memory guidance, and tool schemas.
• In one short diagnostic session, cumulative token events progressed from approximately 29k to 61k to 104k within about 32 seconds, with a large cached-input component. The weekly meter stayed at 77% during those calls.

Please investigate:

1. Whether the remaining-usage UI can remain stale and then jump when a new task starts.
2. Whether memory/context/window-capture features change quota accounting or cause repeated system/tool context injection.
3. Whether cached or automatically injected input is attributed correctly.
4. Whether the UI can distinguish weekly quota remaining from model context-window remaining and expose per-task attribution.

Steps to reproduce

1. Enable the context/memory/window-capture-related feature.
2. Leave Codex mostly idle or perform only a small amount of intentional work.
3. Start or resume a project task.
4. Observe whether the weekly remaining-usage percentage refreshes abruptly.
5. Compare the UI with local JSONL token_count events.

The issue may be intermittent because it appears to involve delayed refresh or accounting.

Expected behavior

• Weekly usage should update promptly enough that a 25-point change is attributable to visible activity.
• Enabling memory/context support should not unexpectedly consume a large portion of the weekly quota.
• Automatically injected and cached context should have transparent, correct quota treatment.
• The UI should clearly label weekly quota versus current context-window capacity.
