chore(planning): archive v1.2 milestone + mark all UAT/verification passed

[SimplicityGuy]

Summary

Closes out the v1.2 — Operator Integration & Insight milestone (shipped v1.2.0 2026-05-19 + v1.2.1 patch). Planning-docs only — no source changes.

Per project rules: this lands via PR on a feature branch (no direct commits to main), and no git tag is created — v1.2.0/v1.2.1 were already cut and pushed on 2026-05-19.

Mark all UAT / verification passed

Maintainer-attested (you confirmed), dated 2026-05-19 — the v1.2.0 ship UAT:

• All 5 outstanding VERIFICATION.md files flipped human_needed → passed (17, 19, 22, 23, 24), with a human_validated: note. The two architectural-decision items (P17 CR-01/CR-02) and the P23 CR-01 LIKE-wildcard concern are recorded as accepted-at-ship, not re-run — kept honest, not silently hidden.
• Scenario + maintainer sign-off boxes checked in 22-/24-HUMAN-UAT.md (prerequisite boxes left unchecked, per the existing convention).
• Every phase HUMAN-UAT.md frontmatter normalized to the canonical status: complete (added frontmatter to 17–20 which had none) so audit-open recognizes them.
• The 3 orphaned quick tasks get canonical SUMMARY.md completion markers.

Result: gsd-sdk query audit-open → 0 open items.

Milestone archival

• ROADMAP.md → milestones/v1.2-ROADMAP.md; REQUIREMENTS.md → milestones/v1.2-REQUIREMENTS.md (then git rm'd the live file).
• ROADMAP.md collapsed to the milestone-grouping form (v1.2 marked SHIPPED 2026-05-19, 78/78 plans).
• MILESTONES.md: replaced the auto-generated 78-line dump with a curated v1.1-style entry — correct ship date, tags rc.1…rc.5 + v1.2.0 + v1.2.1, 6 key accomplishments, validated gates.
• PROJECT.md evolution: 41 v1.2 requirements → Validated, v1.2 milestone section collapsed, Current State / Context / Key Decisions / footer refreshed, Next milestone → v1.3.
• RETROSPECTIVE.md: v1.2 section appended. STATE.md: project reference refreshed (status Awaiting next milestone).

Verification

• audit-open clear (0 items)
• roadmap progress 100% (78/78)
• All diagrams remain mermaid (full v1.2 build-order mermaid preserved in the archive)
• No source files touched

Next

/gsd-new-milestone to define v1.3 — leading candidates: cross-run log search + job concurrency/queuing.
