spec.json: phase -> implementation-complete, new GO decision (2026-07-17)
covering the full feature plus phase 7's residual-gap closure; prior
decision preserved as prior_decision; bug-1443 known_limitations entry
retired (closed by task 7.1) and replaced with the one limitation that
is still genuinely open (task 7.2's first-boot promotion-ordering gap).
tasks.md: task 3.1's implementation note updated from "open, unowned
gap" to "closed by task 7.1" -- it predated that fix and had gone
stale.
Validation evidence: full C suite 9/9 green (incl. libxce test post
rtti-fix), Go suite green (88.1% backend coverage), clean TBD/secrets
grep, live array-soak smoke PASS (O(1) replay time confirmed at
2-element vs 10,000-element scale), cross-task integration verified at
every seam phase 7 touched, 10/10 requirement groups covered, zero
design drift, zero blocked tasks.
