Minimum ISC criteria count: 4 or 8?

[m4nt0de4]

The Ambiguity

v0.5.9 states two different minimums for Ideal State Criteria:

Says 8:

OBSERVE phase (line ~95): "Minimum 8 IDEAL STATE Criteria, 8-12 words each"

Says 4:

Quality Gate QG1 (line ~98): ">= 4 criteria exist"
ISC Requirements table (line ~327): "Minimum 4 criteria"
"Even 'fix a typo' has: file changed, typo gone, no new typos introduced, build passes" (4 criteria)

Question

Is the canonical minimum 4 (with 8 as guidance for non-trivial tasks) or 8 (always, even for trivial tasks)?

The fix-a-typo example with exactly 4 criteria suggests 4 is the real floor, but the OBSERVE phase text says 8.
