1.0.19 — 2026-10-29

• Add the approved independent navy/cool-gray HSE mark, with SVG masters, square PNGs and light/dark composer icons.
• Configure the full Human-Systems Engineering title and branded listing assets in the Codex edition.
• Retain all 22 capabilities and their substantive guidance. Private editions and company branding are unchanged.

1.0.18 — 2026-10-28

Public lifecycle revision 1.11/template 1.10 scope deadline gaps to the relevant activity, keep fictional chronology caveats in provenance and use timing-unknown language in risk headings. Public-only editorial refinement; platform smoke results are recorded separately.

1.0.17 — 2026-10-28

Public lifecycle skill revision 1.10 and template 1.9 clarify timing uncertainty across all sections and distinguish measured impact/schedule gaps from evidence-supported phase progress. Addresses two observed Claude test issues; private editions unchanged.

1.0.16 — 2026-10-28

Defined user-owned project configuration, missing/conflicting-source handling and update preservation. Clarified that profiles do not automatically retheme HTML. Corrected Codex shared-resource copy instructions and neutralized two industry-weighted introductions. Library remains 22 skills.

1.0.15 — 2026-10-28

Added Product Lifecycle Progress Map: living stakeholder overview, maintained template, illustrative example, and neutral HTML companion. Public library now contains 22 skills. Removed workplace branding and proprietary design-token dependencies from this adaptation. Added portable Claude guidance and distinguished private Claude testing from public-edition checks. Existing private packages are unchanged.

1.0.14 — 2026-10-22

Aligned the PEB skill with the published template, added the vision/problem/job/hypothesis opening to the blank template, and included the completed maintenance-planning example. The six-field starter remains sufficient for focused tasks.

1.0.13 — 2026-10-21

Clarified automatic versus explicit skill selection in Codex and how to verify discovery. Skill behavior unchanged.

1.0.12 — 2026-10-21

BDX technology-fit summaries use concise exploration judgments and distinguish investigating bounded assistance from authorizing autonomous actions.

1.0.11 — 2026-10-21

BDX research reviews favor compact opportunity tables and a distinct technology-fit assessment, with proportionate detail and one next inquiry step.

1.0.10 — 2026-10-21

BDX integrates category reasoning into recommendations and avoids duplicating options across priority and category summaries.

1.0.9 — 2026-10-21

BDX integrates category reasoning into recommendations and avoids duplicating options across priority and category summaries.

1.0.8 — 2026-10-21

BDX leads with concise priorities, scales supporting detail to the question, and distinguishes contextual prefill from individual personalization.

1.0.7 — 2026-10-21

BDX explicitly develops AI, agentic, automation and personalization recommendations within the five published categories, with evidence, simpler alternatives, human control and validation.

1.0.6 — 2026-10-21

Clarified the score as a practitioner estimate for comparable benchmarking, before/after comparison and progress reporting, not overall readiness. Made qualitative inquiry and plain-language recommendations explicit defaults. Workbook and article guidance synchronized. No new model-execution or field validation is claimed.

1.0.5 — 2026-10-21

Clarified BDX's purpose as discovery and inquiry that identifies and prioritizes system and human-computer interaction improvements. Incomplete assessments report coverage and findings without an unsolicited partial mean; explicitly requested partial statistics remain distinct from the incomplete overall score. Informed by a private-edition exercise, not public-edition model validation. Other skills and workbook content are unchanged.

1.0.4 — 2026-10-21

Refined BDX output guidance to identify preliminary investigation priorities as provisional and close with a concrete immediate action when useful. This follows review of a private-edition exercise; no public-edition model validation is claimed. Other skills, article and workbook content are unchanged.

1.0.3 — 2026-10-21

Made flexible BDX analysis the default. The skill supports adoption concerns and several related issues or projects without requiring workbook headings or scoring. Moved the optional published scorecard format and rating rules to a linked reference. Retained delivery, measurement and evidence boundaries. No other skill content changed.

1.0.2 — 2026-10-21

Aligned the BDX scorecard template with the single-target article and workbook: snapshot, twelve-dimension evaluation, optional unscored AI review, opportunity matrix and summary. Clarified the four-phase/five-activity relationship, triggers and emotional drivers, and the distinction between calculation completeness and evidence review. Other skill content is unchanged.

1.0.1 — 2026-10-20

Corrected the repository-scoped Codex setup instructions to copy FOUNDATIONS.md and retain attribution files. Recorded isolated Codex discovery and task smoke tests.

1.0.0 — 2026-10-19

First public edition. Includes 21 skills, context profiles, adapter guides, a fictional exercise and foundations map. Synchronized the included PEB template with the reader edition. See VALIDATION.md for performed checks and environment-specific limits.
