+## Context
+
+The Copilot auto-approve gate compares `additions + deletions` from the GitHub pull request payload against a fixed constant (`maxEditedLines` in `scripts/auto-approve/evaluator.go`). The canonical requirement is REQ-009 in `openspec/specs/ci-pr-auto-approve/spec.md`. Today both are set to 300.
+
+## Goals / Non-Goals
+
+**Goals:**
+
+- Raise the threshold to 1000 in spec, code, and tests so behavior stays single-sourced and verifiable.
+
+**Non-Goals:**
+
+- Making the limit configurable via environment or config file.
+- Changing Dependabot behavior or other Copilot gates (authors, file allowlist).
+
+## Decisions
+
+- **Use the same constant and `fmt.Sprintf` reason string as today** — keep `maxEditedLines = 1000` and `edited lines must be < %d` so operators and tests only see the number change. No new observability fields.
+- **Boundary semantics unchanged** — approval requires `additions + deletions < maxEditedLines` (strict less-than), so 1000 total edits still fails when the limit is 1000.
+
+## Risks / Trade-offs
+
+- **Larger auto-approved Copilot PRs** → Mitigation: file allowlist (`*_test.go`, `*.tf`) and author gates unchanged; this only widens the size window for those paths.
+
+## Migration Plan
+
+- Deploy script change together with workflow usage; no data migration. After implementation, sync or archive the change so `openspec/specs/ci-pr-auto-approve/spec.md` matches the delta.
+
+## Open Questions
+
+- None.

+## Why
+
+The Copilot auto-approve path caps total PR edits at 300 lines (`additions + deletions`), which is tight for larger test-only or Terraform-only changes that still fit the file allowlist. Raising the cap to 1000 reduces false rejections while keeping a bounded review surface.
+
+## What Changes
+
+- Raise the Copilot category diff threshold in the canonical spec from strictly less than 300 to strictly less than 1000 total line edits.
+- Align the `scripts/auto-approve` implementation and unit tests with the new threshold and failure messages.
+
+## Capabilities
+
+### New Capabilities
+
+- (none)
+
+### Modified Capabilities
+
+- `ci-pr-auto-approve`: Update REQ-009 (Copilot diff threshold) and the large-PR scenario to use 1000 instead of 300.
+
+## Impact
+
+- `openspec/specs/ci-pr-auto-approve/spec.md` (after apply / sync).
+- `scripts/auto-approve/evaluator.go` (`maxEditedLines`).
+- `scripts/auto-approve/evaluator_test.go` (boundary and message expectations).

+## MODIFIED Requirements
+
+### Requirement: Copilot diff threshold (REQ-009)
+
+The total pull request line edits (`additions + deletions`) for a `copilot` category pull request SHALL be strictly less than `1000`.

+#### Scenario: Large Copilot PR
+
+- GIVEN additions plus deletions are 1000 or more
+- WHEN the Copilot category is considered
+- THEN the threshold gate SHALL fail

+## 1. Implementation
+
+- [x] 1.1 Set `maxEditedLines` to `1000` in `scripts/auto-approve/evaluator.go`.
+- [x] 1.2 Update Copilot diff threshold cases in `scripts/auto-approve/evaluator_test.go`: reject when `additions + deletions` is 1000 or more, expect `edited lines must be < 1000`; rename case descriptions accordingly.
+- [x] 1.3 Add a table-driven case that approves a Copilot PR with total edits strictly between 300 and 1000 (e.g. 400 additions + 500 deletions) so the new band is covered.
+
+## 2. Canonical spec and verification
+
+- [x] 2.1 Update REQ-009 and the large-PR scenario in `openspec/specs/ci-pr-auto-approve/spec.md` to use `1000` instead of `300` (match the delta in this change).
+- [x] 2.2 Run `go test ./scripts/auto-approve/...` and `make check-openspec`.
