claude-opus-5 missing 1m catalog variant: auto-compact fires at 200k instead of 1M

Version

jcode 0.68.0 (builds/stable), macOS arm64

Problem

Auto-compact triggers ~5x too early when running claude-opus-5.
The effective token budget is 200,000 instead of ~1,000,000.

Evidence

The model catalog has [1m] variants for other models but not for Opus 5:

Binary grep on builds/stable/jcode (identical results in builds/shared-server/jcode and builds/versions/0.68.0/jcode):

• opus-5[1m] -> 0 matches
• opus-4-6[1m] -> 5 matches
• opus-5 -> 12 matches (so the base entry does exist)

Catalog bytes around the Opus entries show no 1m variant for Opus 5:

...opus-4-6claude-opus-4-6[1m]claude-sonnet-5claude-sonnet-4-6[1m]claude-opus-4-5...

Logs (~/.jcode/logs/jcode-2026-08-05.log): token_budget=200000 appears 38 times.
No context_limit entries anywhere in the August logs.

Expected

claude-opus-5 should have a [1m] catalog variant (and the matching 1M context beta header) so the token budget is ~1,000,000 and auto-compact fires accordingly.

Actual

It falls back to the 200,000 default, causing premature auto-compact at roughly 20% of the expected context.

Workaround

Switch to claude-opus-4-6[1m] or claude-sonnet-4-6[1m].

Start by locating the model-catalog and context-header handling corresponding to builds/stable/jcode, builds/shared-server/jcode, and builds/versions/0.68.0/jcode; compare the existing claude-opus-4-6[1m] entry with claude-opus-5 and review the August log evidence. Done means claude-opus-5 has the 1m catalog variant and matching 1M context beta behavior, with the effective token budget no longer defaulting to 200,000.
