	2	+issue: 1
	3	+status: working
	4	+---
	5	+# Score exact-five threats and open/closed lines
	6	+
	7	+Claiming issue #1. The existing threat-weights route scores contiguous lines,
	8	+but caps overlines at five and does not recognize broken-line threats. Its
	9	+claim has expired; no delivery is attached to this issue. This route starts
	10	+with the project's starter and will add exact-five tactical priorities and
	11	+line scoring, including gaps, without changing the referee or field.
	12	+
	13	+## Validation plan
	14	+
	15	+Run focused tactical/protocol tests and the full season check with
	16	+`python3 -I referee/play.py check routes/codex-line-threats`.
	17	+Compare with the published starter score of 0.5 and existing threat route
	18	+score of 0.833333. Report measured outcomes, including losses.
	19	+
	20	+## Next
	21	+
	22	+Implement line scoring and exact-five tactical tests, then run the season's
	23	+field before delivering a pull request for issue #1.
