* test(#3782): step 1.6 must segment verification debt by the archived stamp
* fix(#3782): segment verification debt by the archived_milestone stamp in progress step 1.6
progress.md step 1.6 read the cross-population summary.total_items as
current-milestone debt while claiming the whole query respects milestone
boundaries. The active tree is milestone-filtered; archived trees are
deliberately unfiltered (each result stamped archived_milestone), so a
healthy current milestone presented six shipped milestones' still-open
items as CURRENT debt on every /gsd-progress run (#3782).
Step 1.6 now computes CURRENT_DEBT/ARCHIVED_DEBT via jq selects on the
stamp, tracks archived_debt separately (visible with its own labeled
header — segmented, never hidden), corrects the scoping claim, and
unwraps the CLI's @file: large-payload redirect before jq so counters
cannot silently read 0. A structural guard test pins the segmentation.
parse_gap_files stays deliberately cross-population.
Emitted-Drift-Ack-Growth: progress.md — #3782: +1406 bytes — step 1.6 gains the CURRENT_DEBT/ARCHIVED_DEBT segmentation jq, the @file: unwrap, and the archived-visibility paragraph; parse-gap paragraph reworded to match
