fix(server): Claude context meter no longer shows an auto-compact point when auto-compaction is off - #36417
No changes were needed in this round. The brief listed nothing to change, and PR #36417 at e5c39c7 passed all 35 checks; Macroscope approved it. The thread-transfer report shows every provider within its ceilings. CodeRabbit left one finding, rated Minor, asking to switch decodeClaudeCompactSettings from Schema.fromJsonString to fromLenientJson. Minor is below the bar for fixing in this step, and the finding is also wrong for this repo. The existing threshold table in ClaudeAdapterV2.test.ts expects '{"autoCompactWindow":500000,}' (trailing comma) and '{/* invalid */ "autoCompactWindow":500000}' to give threshold undefined. Strict parsing of these settings is therefore intended, and the suggested change would break those rows. The fix itself is unchanged: resolveAutoCompactWindow returns no window when DISABLE_COMPACT or DISABLE_AUTO_COMPACT is truthy, or when autoCompactEnabled is false. With no threshold, the meter draws no tick and shows no compaction text.
On origin/main dd2678d: created a scratch git project whose .claude/settings.json contains {"autoCompactWindow":400000,"autoCompactEnabled":false} (the Claude adapter reads project settings files as well as user ones). T3's Claude 'Auto-compact after' setting was left empty. Started T3CODE_DEV_SEED=0 vp run dev on fresh state, added the project with t3 project add, then ran t3 thread start --provider claudeAgent --model claude-opus-5-5 --wait <project> "Reply with just: hi", a real Claude Code turn. The provider turn projection in the worktree's statev2.sqlite stored tokenUsage with "autoCompactThreshold":367000 and "maxTokens":1000000 and no compactsAutomatically field. The client renders that through formatContextWindowCompactionMessage() as 'Compacts automatically at about 367,000 tokens.', and packages/client-runtime/src/state/contextWindow.ts hard-codes compactsAutomatically: true. The preview browser could not open on this host (AppArmor), so the tooltip itself was not captured. Also added two rows to the existing threshold table in ClaudeAdapterV2.test.ts (autoCompactEnabled:false in Claude settings; DISABLE_AUTO_COMPACT=1 in the environment with T3's window set to 400000). Both fail on main with [367000, 367000, 367000] where undefined is expected.
Evidence
Created identical fresh projects with Claude settings {"autoCompactWindow":400000,"autoCompactEnabled":false}, left T3's auto-compact window empty, and ran real Claude Opus 5.5 turns asking for hi. Opened each thread and hovered its context meter. Chromium 151, light theme, 1440×1000 viewport; captures crop the top 400 pixels.
DISABLE_AUTO_COMPACT and DISABLE_COMPACT environment-variable variants were not exercised; this comparison used autoCompactEnabled:false in project settings.
The no-window variant was not separately captured; both sides used autoCompactWindow:400000.
Tests
This round I ran no local tests because no code changed. CI passed all 35 checks on e5c39c7. In the earlier round: the ClaudeAdapterV2 threshold tests passed 22/22, the full ClaudeAdapterV2.test.ts passed 413/413, and vp run check:changed passed.
Not in this change
packages/client-runtime/src/state/contextWindow.ts hard-codes compactsAutomatically: true for live usage and compaction-derived snapshots, but no UI reads compactsAutomatically today, so it has no visible effect.
formatContextWindowCompactionMessage's fallback 'Context compacts automatically when needed.' is never rendered by the web meter, which only calls it when a threshold exists. It could be removed or reworded separately.
The adapter still never sets the contract's compactsAutomatically field. Populating it would only matter once a client reads it.
Claude Code's older global-config location for autoCompactEnabled (~/.claude.json) is not read. Only the settings files and --settings launch args are.
CodeRabbit's suggestion to read compact settings with the lenient JSON decoder. It is rated Minor and conflicts with existing tests that expect strict parsing of these settings.
client-runtime contextWindow.ts hard-codes compactsAutomatically: true, but no UI reads that field today.
The formatContextWindowCompactionMessage fallback text is never rendered by the web meter.

…pact is off
Failing rows for #36410: autoCompactEnabled=false in Claude settings and
DISABLE_AUTO_COMPACT both still produce an auto-compact threshold.
Co-Authored-By: Claude Opus 5.5 <[email protected]>
Macroscope's review found this PR approvable — The context meter now omits its auto-compaction point when Claude settings explicitly disable compaction. This changes usage reporting without changing compaction behavior or product defaults.
You can add or adjust custom eligibility rules. Learn more.
The Claude adapter now returns no auto-compaction threshold when a recognized disable environment variable is truthy or the first applicable autoCompactEnabled setting is false. Tests cover disabled settings and the DISABLE_AUTO_COMPACT environment variable.

Summary
Disable checks and threshold resolution apps/server/src/orchestration-v2/Adapters/ClaudeAdapterV2.ts, apps/server/src/orchestration-v2/Adapters/ClaudeAdapterV2.test.ts
The compact-settings schema accepts autoCompactEnabled. Threshold resolution checks disable environment variables and settings in precedence order. It returns no threshold when disabled. Tests cover settings and environment-variable cases.
The change hides the auto-compact threshold when Claude auto-compaction is disabled. A settings file with a trailing comma may still show a threshold, so this edge case should be fixed. The risk is low and limited to the display.

Explanation
The title states the main change: the Claude context meter no longer shows an auto-compact point when auto-compaction is off. This matches the adapter change that returns no threshold when DISABLE_COMPACT or DISABLE_AUTO_COMPACT is truthy, or when autoCompactEnabled is false. The title is long (99 characters), but it is specific and conventional.
Full details: Linked Issues check
Explanation
[#36410] The requirement is that the Claude meter shows no auto-compact threshold when Claude Code auto-compaction is off. The diff in ClaudeAdapterV2.ts adds three gates in resolveAutoCompactWindow, which run before the autoCompactWindow setting is read: (1) DISABLE_COMPACT and DISABLE_AUTO_COMPACT, resolved through resolveClaudeEnv and checked with isClaudeEnvTruthy (trimmed, lowercased, in {1,true,yes,on}); (2) autoCompactEnabled === false from launch-arg settings, then settings files in precedence order. Each gate returns "", so no threshold is reported. decodeClaudeCompactSettings gains an optional autoCompactEnabled key to support gate (2). The test file adds two rows (autoCompactEnabled:false in user settings; DISABLE_AUTO_COMPACT=1 with window 400000) that expect undefined. The issue's suggested contract change (compactsAutomatically: false) is not implemented. The PR explains why: with no threshold, the web meter draws no tick and shows no compaction text. I did not inspect the caller in ThreadDetailsUsage. Formatting still returns 'Context compacts automatically when needed.' when no threshold is passed, so the no-text claim depends on that caller gating, which the PR asserts but I did not verify. The #22654 handoff budget and the ~/.claude.json location are out of this requirement set as stated in the PR.
Full details: Out of Scope Changes check
Explanation
All changes relate to #36410. The diff touches only ClaudeAdapterV2.ts (new truthy-env helper, compact-settings schema key, and the auto-compaction gates) and ClaudeAdapterV2.test.ts (two threshold rows). No client, contract, or unrelated files change in the reviewed diff. The helper and gates implement the requested off-switch behavior. The PR's documented exclusions (no client change, no compactsAutomatically population, no ~/.claude.json read) are scope decisions, not out-of-scope changes.
Full details: Description check
Explanation
The description is detailed and covers the problem (meter shows a compaction threshold and tooltip when Claude auto-compaction is disabled, referencing issue #36410), the change (resolveAutoCompactWindow returns no window when DISABLE_COMPACT/DISABLE_AUTO_COMPACT is truthy or autoCompactEnabled is false), scope (links the issue and explains the bug fix), and verification (reproduction on main versus the fix, before/after screenshots, unit test rows failing on main, and test counts). It also states what was not checked: the DISABLE_* environment variants were not exercised in the browser, and the no-window variant was not captured separately. The template's Scope and Verification sections are satisfied. Minor gaps: the 'Not in this change' section repeats several items, and the description is long relative to the template's guidance. The agent attribution is present as the template requests. The description does not use a conventional commit title, but the title is not part of the body under review.

Minor · Functional Correctness · Quick win
Use the lenient JSON decoder for the auto-compact settings read.
decodeClaudeCompactSettings uses strict JSON. The repository's test fixture states that Claude accepts comments and trailing commas in settings files. A settings file with "autoCompactEnabled": false and a trailing comma fails this decode. The orElseSucceed at line 5493 then drops the value. With a T3 window such as "400000", the adapter reports a threshold even though Claude has auto-compaction disabled.
The same decoder also feeds the read at line 5534, so that read will accept the same syntax after this change.
Add a trailing-comma case to the existing auto-compact threshold tests.
