v0.28.0

Added

• architecture skill — Cross-Section Consistency Gate (skill manifest 0.9.0 → 1.0.0).
  Prevents downstream stages from discovering architecture gaps too late by adding
  a Cross-Section Consistency Pass inside architecture --mode design.

  • prompts/22_architecture_draft.md — adds step 2c: Cross-Section
    Consistency Pass verifying (i) every MVP operation in §23 exists in §12,
    (ii) every user-visible state in §23.3/§23.4 maps onto §14, (iii) every
    human-review action in §23.6 has a §12 contract + §14 transition + §16 audit
    event + §18 failure behaviour, (iv) every progress item in §23.4 has a §16
    observability event, (v) §24 handoffs reference only formalized or deferred
    operations. Gaps logged in §25 and §27.
  • prompts/23_quality_gate_self_check.md — adds five v0.9.0 cross-section
    consistency gates (20–24); updates Instructions to include them in the §26
    table.
  • templates/architecture_design_template.md — adds
    ### Cross-Section Consistency Gate sub-table to §26.
  • SKILL.md — adds quality gate 29.
  • manifest.json — bumped to 1.0.0.

• ux-design skill — MVP phase and testability metadata (skill manifest 0.2.0 → 0.3.0).
  Enables implementation-plan to convert E2E seeds into concrete test tasks
  without guessing and to scope MVP-0 correctly.

  • prompts/07_user_stories.md — requires phase/release-gate header on
    every story (Phase, Primary Surface, Release Gate, Depends On); updates
    validation gate.
  • prompts/10_e2e_scenario_seeds.md — requires testability metadata block
    on every seed and a Testability Summary Table in §20; updates validation gate.
  • templates/e2e-scenario-template.md — adds testability metadata fields
    to skeleton and worked example.
  • templates/user-story-template.md — adds phase + release-gate fields;
    updates Rules.
  • prompts/13_quality_gate_self_check.md — adds six gate rows, five fail
    conditions, six warning conditions.
  • SKILL.md — adds quality gate 11.
  • manifest.json — bumped to 0.3.0.
