📝 WalkthroughWalkthroughThe scan agent now records aggregate token-budget exhaustion during dispatch. Tests verify the state through direct dispatch and end-to-end JSON scan reporting, including warnings and optional field behavior. ChangesScan budget reporting
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to The new JSON test expects the wrong scan status for a token-budget stop, which would reject the intended behavior and should be corrected before merge. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

scan already detects the aggregate token-budget stop (it prints the
"[ocr] token budget reached" line and records a token_budget_reached
warning) but BudgetExceeded() was hard-coded false, so
summary.budget_exceeded never appeared in `ocr scan --format json`.
The write goes next to `budgetHit = true` in dispatchBatch's per-file
gate. That is the only site that sets budgetHit, and it covers all three
exits that carry the stop out of dispatchBatch: normal return, ctx-cancel
return, and the caller's `if budgetHit { break }`. Setting it at the
dispatchSubtasks break instead would lose it on the ctx-cancel path.
Plain bool, no mutex: dispatchBatch's loop is the only writer, it runs on
the caller's goroutine, and the value is read by emitRunResult after Run
returns. The spawned subtask goroutines never touch it. Matches the
existing internal/agent.Agent.budgetExceeded field.
Status and exit code are untouched — reaching the budget is a controlled
truncation, so out.Status stays the warning-derived value.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Keep the budget-stop status as success.
Line 60 expects completed_with_warnings, but the PR contract requires scan status to remain success after an aggregate token-budget stop. A conforming implementation will fail this test. Do not change production output to satisfy this expectation.
Proposed fix
- {name: "budget stop sets budget_exceeded", budget: 120_000, want: true, wantStatus: "completed_with_warnings"},
+ {name: "budget stop sets budget_exceeded", budget: 120_000, want: true, wantStatus: "success"},📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Description
ocr scan --format json --max-tokens-budget Nalready detects the aggregate budget stop — it records atoken_budget_reachedwarning and stops dispatching — butsummary.budget_exceededstayedfalse, becausescan.Agent.BudgetExceeded()was hardcoded toreturn false(internal/scan/agent.go:229). Automation consuming the JSON had to parse the warning list to tell a complete scan from one truncated by the budget.The signal already existed inside scan; it just never reached the result provider.
The flag is set where
budgetHitis set, not at thebreak.dispatchBatchhas three exits that carrybudgetHit, and the ctx-cancel exit at:638reachesdispatchSubtasks'err != nilreturn at:528— which fires before theif budgetHitcheck at:547. Writing the flag at the break would silently lose it on cancel-after-budget-hit. One write at:628covers all three exits.No mutex or atomic:
budgetHit = trueruns indispatchBatch's own loop body, beforesem <- struct{}{}and outside the worker closure, anddispatchBatchhas one caller in a sequential batch loop — one writer on one goroutine, read only afterRunreturns.internal/agent/agent.go:176stores the same flag as a plainboolon the diff-review path.make testruns with-race, so this is enforced rather than argued.Scan's status semantics are unchanged: it publishes no run manifest, so
statusstayssuccess, andomitemptykeepsbudget_exceededout of the JSON entirely when the gate does not trip.Limitation
The new CLI-level test drives the real
*scan.Agentand the realemitRunResult, not a spawnedocrbinary — no test in this repo spawns it, and doing so would need live provider credentials. The flag-parsing layer betweenparseScanFlagsandscan.Args.MaxTokensBudgetis covered separately bycmd/opencodereview/scan_cmd_test.go:145.Type of Change
