[BUG] Max plan: context window stuck at 200K instead of 1M (hasExtraUsageEnabled not updated after Pro → Max upgrade)

What's Wrong?

After upgrading from Pro to Max 5x plan on March 21, 2026, Claude Code context window remains at 200K instead of the expected 1M. The /context command shows 65k / 200k tokens (32%). The organization-level flag hasExtraUsageEnabled in .claude.json is stuck at false with cachedExtraUsageDisabledReason: "org_level_disabled" — inherited from the original Pro plan authorization on March 8, 2026, and never updated after the Max upgrade. Manually editing the file has no effect — the server overwrites it back to false on every launch.

What Should Happen?

Context window should show Xk / 1000k for Max 5x plan subscribers. The hasExtraUsageEnabled flag should be true at the organization level.

Error Messages/Logs

From .claude.json (oauthAccount block):
"hasExtraUsageEnabled": false

From .claude.json (top level):
"cachedExtraUsageDisabledReason": "org_level_disabled"

/context output:
Tokens: 65k / 200k (32%)

Steps to Reproduce

1. Create account on Pro plan (Feb 25, 2026)
2. Authorize Claude Code for the first time while on Pro (Mar 8, 2026) — organization is created with extraUsage: disabled
3. Upgrade to Max 5x plan (Mar 21, 2026)
4. Run /context in Claude Code — shows 200k limit instead of 1000k
5. Run /logout then /login — reauthorize — limit still 200k
6. Manually edit .claude.json to set hasExtraUsageEnabled: true — server overwrites it back to false on next launch
