[Duang777]

Goal And Delivered Outcome

• Outcome basis / optional anchor: self-found core defect. No public issue; the request in this PR is the basis.
• Goal/source and gap: goal_quota_with_spend_ledger in loopx/quota.py computed current_time - timedelta(hours=int(window_hours)) with no overflow handling. configure-goal --quota-window-hours accepts any finite positive number and a registry can hold any number. collect_history evaluates every registered goal in one pass.
• Observable before → after, with the validation row that proves it: A goal with window_hours of 1e8 or more raised OverflowError (date value out of range, or from timedelta itself at 1e12), and collect_history failed for the whole registry including goals with a 24-hour window. After: such a window covers all history, the goal keeps its configured window and counts all of its spends, and the other goals are unaffected. Rows: regression_parity, unit.
• Issue/task and intended base: none. Base is main at 7bb1b01.

Author Declaration

Implemented against

• Specification and revision: no written specification; the request in this PR is the basis.
• Criteria:

Criterion (spec clause)	Disposition	Symbol / path	Test or command
One goal's configuration must not break reads for other goals	implemented	goal_quota_with_spend_ledger in loopx/quota.py	tests/control_plane/test_quota_rolling_window_projection.py::test_unrepresentable_window_covers_all_history_without_crashing

• Self-check before submission: reproduced the defect on the unfixed code, then confirmed the new test fails before and passes after. Did not run the full suite or CI-equivalent gates locally. Fixed at the read rather than clamping at configure time so a hand-edited registry is covered too. Severity is medium: it needs an extreme configured value.

Scope And Continuation

• Completed scope and remaining work: complete within this scope. No limit is added to --quota-window-hours.
• Slice boundary / successor: N/A, one independent defect.

Validation

• Tested revision: b0d57936c2eb202f0697777fa04e07ac3200ab15 for the diff; local runs used a working tree whose touched files were blob-identical to main 7bb1b01 before the change.
• Run state: finished
• Input classes: synthetic

Check kind	Result	Public-safe evidence / limitation
regression_parity	passed	The test, parametrized over 10**8, 10**12 and 1e12, fails 3 of 6 cases on the unfixed code and passes with the fix.
unit	passed	Also test_quota_ledger_integrity.py, test_quota_paused_precedence.py and test_quota_plan_policy.py: 62 passed; ruff check clean.

• Coverage and gaps: configure_goal could not be driven end to end on the local tree, so the repro went through collect_history and a hand-written registry.

Frontend / Visual Evidence

Boundary Checklist

• Neither the diff nor this PR body/comments/attachments disclose private state, credentials, raw traces or verifier output, internal links, or local machine paths (including .loopx/, .codex/goals/, and live ACTIVE_GOAL_STATE.md).
• I did not duplicate maintainer-owned benchmark work unless a maintainer split out a public issue for it.
• I kept the change scoped to the linked issue/task.
• Existing English/Chinese RFC pairs (including ledger entries) both have a diff, and the local premerge check passes, or no paired RFC changed. No RFC changed.
• I completed the visual evidence section for UI changes, or marked UI impact none.
• Every commit includes a DCO Signed-off-by trailer (git commit -s).
