Changelog

How implementers should use this log

Read the changelog as the public record of what changed, whether the change is additive, corrective, policy-oriented, or breaking, and what migration work a downstream implementation should perform before release.

Release history

This log records public changes across the UAIX site and standards record so implementers can trace revisions, compatibility expectations, and governance signals without relying on informal notes.

2026-05-08 | Launch-grade public-record alignment pass

Change type: Additive route, discovery, documentation, validator-workflow, and handoff-source alignment across the public record.

  • Affected records: Home, Specification, UAI-1, Schemas, Examples, Tools, Validator, Implementations, Governance, discovery manifests, and launch-surface audit scripts.
  • Migration note: long-form public aliases for WordPress Publication Track, .NET Bridge Track, AGENTS.md UAI linking, and Agent File Handoff now redirect to the canonical records while remaining discoverable for agents and reviewers. The current proof path still runs through schemas, registry, examples, validator evidence, implementation tracks, conformance pack, and the release trail.
  • Support-claim effect: this pass improves findability and evidence alignment without creating SDK, CLI, certification, official adapter, hosted-import, automatic-write, automatic-sync, endorsement, or broader runtime-support claims.
  • Reference paths: Home, UAI-1, Tools, Implementations, Governance, and References and Contributors.

2026-05-01 | LLM Wiki report-preservation hardening

Change type: Additive package and archive-consolidation guidance.

  • Affected records: Using UAI Packages With An LLM Wiki, AI Memory Package Wizard, the generated .uai/LLM_WIKI_MEMORY_PLAN.md, the experimental Project Handoff plugin package scaffolding, root handoff docs, local .uai files, and AIWikis outcome-routing memory.
  • Migration note: when a package or source-site archive is consolidated into an LLM Wiki or AIWikis-style cold memory, preserve original processed reports with source paths, destination paths, file counts, checksums, dispositions, and discoverable summary/index updates. Summaries, staged drafts, and hot-context snapshots are not enough if future work may need original wording.
  • Support-claim effect: this improves preservation guidance only. It does not create automatic LLM Wiki sync, hosted import validation, repository writes, SDKs, CLIs, certification, endorsement, official adapters, or validator-backed conformance evidence.
  • Reference paths: Using UAI Packages With An LLM Wiki, AI Memory Package Wizard, Agent File Handoff, and Changelog.

2026-05-01 | Project Handoff context-budget guide

Change type: Additive guide and discovery-surface hardening.

  • Affected records: Project Handoff Context Budget, Project Handoff, AI Memory, Using UAI Packages With An LLM Wiki, root handoff docs, local .uai files, well-known manifests, and focused memory regression coverage.
  • Migration note: keep AGENTS.md, readme.human, and typed .uai files as hot context containing current truth, constraints, decisions, active routes, and targeted checks. Move bulky research, old reports, chat transcripts, roadmap history, and pre-slim snapshots into LLM Wiki or AIWikis-style cold memory with source path, final path, checksum, actor, time, summary, and disposition.
  • Support-claim effect: this is context-budget guidance and dogfood practice. It does not create automatic LLM Wiki sync, hosted import validation, repository writes, SDKs, CLIs, certification, endorsement, official adapters, or validator-backed conformance evidence.
  • Reference paths: Context Budget guide, Project Handoff, AI Memory, and Changelog.

2026-05-01 | Project Handoff coding-agent compatibility guide

Change type: Additive guide, pointer, and discovery-surface clarification.

  • Affected records: Project Handoff, OpenAI/Codex guide, Coding Agents guide, AI Memory, root handoff docs, local .uai files, well-known manifests, and focused handoff regression coverage.
  • Migration note: coding-agent-specific files should stay thin pointers back to AGENTS.md, readme.human, and .uai records. Use one repo-local bundle across Codex, Claude Code, Cursor, GitHub Copilot, Gemini Code Assist, local agents, vendors, and humans instead of duplicating project truth per tool.
  • Support-claim effect: this is compatibility guidance and repo-local pointer structure. It does not create official vendor adapters, SDKs, CLIs, hosted import validators, automatic repository writers, certification, conformance evidence, or endorsement claims.
  • Reference paths: Coding Agents guide, Project Handoff, Roadmap, and Changelog.

2026-05-01 | Project Handoff OpenAI-compatible memory positioning

Change type: Additive positioning, guide, and discovery-surface clarification.

  • Affected records: Project Handoff, Using UAIX Project Handoff with OpenAI Agents and Codex, AI Memory, roadmap state, root handoff docs, local .uai files, well-known manifests, and focused AI Memory regression coverage.
  • Migration note: Project Handoff is now framed as portable project memory, governance, and review context for any agent runtime. The public shorthand is: OpenAI runs the agents; Project Handoff preserves the project memory.
  • Support-claim effect: this is compatibility guidance and repo-local context structure. It does not create an OpenAI replacement, agent runtime, scheduler, tool-calling framework, official OpenAI adapter, hosted import validator, automatic repository writer, trace exporter, SDK, CLI, certification, or endorsement program.
  • Reference paths: Project Handoff, OpenAI/Codex guide, Roadmap, and Changelog.

2026-05-01 | AI Memory Package Wizard staged review flow

Change type: Additive wizard UX and review-boundary hardening.

  • Affected records: AI Memory Package Wizard, AI Memory, route copy, root handoff docs, local .uai files, and focused AI Memory regression coverage.
  • Migration note: the wizard now moves through Preset, Basics, Operations, Protocols, Receiver, and Review and Export steps. Required fields validate before forward movement, local browser drafts can be restored, sensitive or high-risk selections auto-enable review gates, optional LLM Wiki planning stays inside the receiver step, and export actions live on the review step beside lazy generated-artifact previews.
  • Support-claim effect: this remains local package planning over canonical starter bundles. It does not create hosted import validation, automatic repository writes, automatic LLM Wiki sync, provider execution tests, SDK, CLI, certification, endorsement, WordPress admin installation, or automatic site writes.
  • Reference paths: AI Memory Package Wizard, AI Memory, Roadmap, and Changelog.

2026-04-30 | AI Memory Package Wizard protocol expansion

Change type: Additive generated-memory operating protocol expansion.

  • Affected records: AI Memory Package Wizard, homepage package-building CTA, AI Memory, roadmap state, machine-readable roadmap state, root handoff docs, local .uai files, and focused AI Memory regression coverage.
  • Migration note: the wizard now asks for memory update policy, source authority policy, change risk level, conflict resolution policy, evidence ledger path, memory update targets, and rollback strategy. These choices populate UAI_MEMORY_SYSTEM_PROFILE.md, UAI_MEMORY_RECEIVER_BRIEF.md, UAI_MEMORY_STARTUP_PACKET.md, the manifest overlay, and the optional .uai/LLM_WIKI_MEMORY_PLAN.md so the generated package includes operational definitions instead of only empty selections.
  • Support-claim effect: these remain local generated planning files beside canonical starter bundles. They do not create hosted import validation, automatic repository writes, automatic LLM Wiki writes or sync, SDK, CLI, certification, endorsement, or UAI-1 conformance evidence.
  • Reference paths: AI Memory Package Wizard, AI Memory, Roadmap, and Changelog.

2026-04-30 | AI Memory Package Wizard system profile release

Change type: Additive operating-profile and package-output hardening.

  • Affected records: AI Memory Package Wizard, AI Memory, homepage package-building CTA, roadmap state, root handoff docs, local .uai files, machine-readable roadmap state, and focused AI Memory regression coverage.
  • Migration note: the wizard now generates UAI_MEMORY_SYSTEM_PROFILE.md beside the startup packet, receiver brief, overlay, optional LLM Wiki plan, copied file deck, and canonical starter ZIP. The profile records single-user versus multi-user collaboration, UAI-only versus UAI plus Wiki memory architecture, unit and integration test posture, test timing, deployment strategy, code review strategy, release gates, evidence expectations, and placeholders such as {PROJECT_ROOT}, {UNIT_TEST_COMMAND}, and {DEPLOY_COMMAND_OR_STEPS} that the receiving AI must fill from the actual system.
  • Support-claim effect: this is a local generated operating file and test/deployment planning aid. It does not create hosted import validation, automatic repository writes, automatic LLM Wiki sync, SDK, CLI, certification, endorsement, WordPress admin installation, or UAI-1 conformance evidence.
  • Reference paths: AI Memory Package Wizard, AI Memory, Roadmap, and Changelog.

2026-04-30 | AI Memory Package Wizard receiver brief and startup packet release

Change type: Additive package-startup and homepage CTA hardening.

  • Affected records: AI Memory Package Wizard, AI Memory, homepage package-building CTA, roadmap state, root handoff docs, local .uai files, and focused AI Memory regression coverage.
  • Migration note: the wizard now generates UAI_MEMORY_RECEIVER_BRIEF.md and UAI_MEMORY_STARTUP_PACKET.md beside the package model, manifest overlay, copied file deck, optional .uai/LLM_WIKI_MEMORY_PLAN.md, and canonical starter ZIP. Use the receiver brief as the first-read instruction, and use the startup packet as the one-file operator bundle for the next human, team, or AI before broad work starts.
  • Support-claim effect: these are local generated instruction files that name read order, first-response expectations, first task, success evidence, boundaries, selected files, and targeted checks. They do not create hosted import validation, automatic repository writes, automatic LLM Wiki sync, SDK, CLI, certification, endorsement, or UAI-1 conformance evidence.
  • Reference paths: AI Memory Package Wizard, AI Memory, Roadmap, and Changelog.

2026-04-30 | AI Memory Package Wizard LLM Wiki plan hardening

Change type: Additive package-planning and UX hardening.

  • Affected records: AI Memory Package Wizard, AI Memory, roadmap state, root handoff docs, local .uai files, and focused AI Memory regression coverage.
  • Migration note: when a project uses an LLM Wiki, the wizard can now generate an .uai/LLM_WIKI_MEMORY_PLAN.md file with memory steward, source collection, archive target, transfer evidence log, promotion targets, source boundary, a memory routing matrix, required transfer evidence, and promotion gates. Generated files stay visible in narrowed decks and the review panel now reports readiness items before export.
  • Support-claim effect: this remains a local planning artifact beside the canonical starter ZIP and copied files. It does not create hosted import validation, automatic repository writes, automatic LLM Wiki writes, bidirectional sync, SDK, CLI, certification, endorsement, or UAI-1 conformance evidence.
  • Reference paths: AI Memory Package Wizard, AI Memory, Roadmap, and Changelog.

2026-04-29 | Agent File Handoff archive-to-LLM-Wiki history clarification

Change type: Additive public handoff lifecycle clarification.

  • Affected records: Agent File Handoff, Project Handoff, AI Memory, root AGENTS.md, root readme.human, local .uai handoff files, helper navigation, and canonical reference docs.
  • Migration note: active files still move through visible review and disposition before they are archived. When a human explicitly asks an LLM Wiki implementation such as AIWikis.org to consolidate already-dispositioned archive files, the pickup must record source path, final memory path, checksums, disposition, actor, time, and transfer evidence, then update the AIWikis history, log, index, or wiki graph before the source archive copy is removed.
  • Support-claim effect: AIWikis archive memory is provenance and long-term system memory, not routine UAIX intake, public UAIX authority, certification, endorsement, or UAI-1 conformance evidence.
  • Reference paths: Agent File Handoff, Project Handoff, AI Memory, Roadmap, and Changelog.

2026-04-28 | Project Handoff package dogfood correction

Change type: Package-scaffold and evidence-boundary correction from AIWikis.org dogfood.

  • Affected records: UAIX Agents Protocol, Project Handoff, Agent File Handoff, roadmap state, root handoff docs, and the UAIX-produced Project Handoff ZIP package.
  • Migration note: generated handoff packages should include the active agent-file-handoff/Content, Improvement, and Archive folders plus a fuller loaded .uai set: context, stack, architecture, constraints, decisions, progress, operations, test plan, style, sources, prompts, file handoff, and intake index.
  • Support-claim effect: this improves experimental dogfood packaging and validation. It still does not create official generator, hosted validator, SDK, CLI, certification, endorsement, or conformance support.
  • Reference paths: UAIX Agents Protocol, Project Handoff, Agent File Handoff, and Roadmap.

2026-04-28 | AI Memory starter bundle release

Change type: Additive public handoff, route, and download-surface expansion.

  • Affected records: AI Memory, Project Handoff, Reports, Roadmap, launch-surface audits, discovery manifests, and canonical workspace docs.
  • Migration note: use AI Memory as the broad public phrase for durable AI project context, use Project Handoff as the transfer configuration, use the supported bundle chooser when the lifecycle or trust boundary differs, and use an LLM Wiki when deep internal documentation needs a larger searchable memory surface. The /AI_Memory entry path redirects to the canonical /en-us/ai-memory/ page as the intended non-canonical search entry alias.
  • Support-claim effect: UAIX now publishes supported starter ZIPs generated from canonical templates, generated manifests, and the same resolved samples rendered on AI Memory and Project Handoff. Hosted generators, upload validators, SDKs, CLIs, certification, and endorsement services remain outside current support.
  • Reference paths: AI Memory, Project Handoff, LLM Wiki comparison report, Roadmap, and Changelog.

2026-04-27 | Agent File Handoff archive boundary release

Change type: Additive handoff lifecycle clarification.

  • Affected records: Agent File Handoff, Project Handoff, UAIX Agents Protocol, root AGENTS.md, root readme.human, local .uai handoff files, intake scripts, and LlmWikis dogfood guidance.
  • Migration note: active files belong in agent-file-handoff/Content/ or agent-file-handoff/Improvement/. After disposition, move the source file to agent-file-handoff/Archive/; routine AI intake should ignore archived files unless a human explicitly names one or moves it back into an active bucket.
  • Support-claim effect: the archive is local source retention only. It is not public content, a discovery surface, certification evidence, or an automatic AI task queue. Folder-local README instructions are not part of the base pattern; durable instructions belong in AGENTS.md and .uai files.
  • Reference paths: Agent File Handoff, Project Handoff, UAIX Agents Protocol, Roadmap, and Changelog.

2026-04-27 | readme.human handoff briefing release

Change type: Additive Project Handoff clarification and dogfood expansion.

  • Affected records: Project Handoff, UAIX Agents Protocol, root readme.human, root AGENTS.md, local .uai handoff files, the Project Handoff WordPress prototype package, and LlmWikis dogfood guidance.
  • Migration note: active projects should add a root readme.human beside AGENTS.md as a human-facing briefing from the AI perspective. Use it to tell people what the AI needs to know, what it will defend, and what humans should make explicit before broad work.
  • Support-claim effect: readme.human is a briefing aid, not an authority layer. It does not override AGENTS.md, project constraints, system instructions, repository rules, or current human requests.
  • Reference paths: Project Handoff, UAIX Agents Protocol, Roadmap, and Changelog.

2026-04-27 | Agent File Handoff active intake release

Change type: Additive local handoff and dogfood tooling expansion.

  • Affected records: Agent File Handoff, Project Handoff, UAIX Agents Protocol, root AGENTS.md, local .uai handoff files, intake scripts, and the Project Handoff WordPress prototype package.
  • Migration note: active projects should make an active-bucket scan and review gate part of AGENTS.md handoff load so files in Content/ and Improvement/ are noticed and processed even when the human prompt does not mention them. Do not require watchers, daemons, queue folders, manifests, cron loops, out-of-chat auto-pickup, or bucket-local README files. Inspect and disposition every needs-agent-review item in .uai/intake-index.uai before unrelated broad edits, then move processed source files to Archive/.
  • Support-claim effect: UAIX now dogfoods local file-intake indexing into project-state artifacts, while hosted generators, upload validators, SDKs, CLIs, certification, and endorsement remain outside current support.
  • Reference paths: Agent File Handoff, Project Handoff, UAIX Agents Protocol, Roadmap, and Changelog.

2026-04-25 | Project handoff and AGENTS.md .uai audit hardening

Change type: Additive developer-handoff and launch-QA clarification.

2026-04-24 | Launch readiness governance gate release

Change type: Additive go-live hardening across the public governance and evidence surface.

2026-04-24 | Conformance fixture pack release

Change type: Additive validator-regression and release-evidence expansion.

  • Affected records: Adoption Kit, Conformance Pack, API Reference, Roadmap, discovery, production response checks, and the public UAIX REST surface.
  • Migration note: release packets can now carry reusable positive keyed/minified-keyed/keyless validator cases, canonical-hash equivalence metadata, and negative checks for missing profile, missing required fields, undeclared fields, invalid traceparent, DID/VC trust evidence, keyless shape, keyless overflow, and unsupported alias.
  • Support-claim effect: current validator behavior is easier to regression-test before launch, while alias maps and binary envelopes remain future work until their own fixtures and route behavior exist.
  • Reference paths: Adoption Kit, Conformance Pack, Roadmap, Changelog, and News.

2026-04-24 | Implementation evidence checklist release

Change type: Additive conformance-evidence and developer-handoff expansion.

  • Affected records: Adoption Kit, Conformance Pack, API Reference, Roadmap, catalog discovery, and the public UAIX REST surface.
  • Migration note: release packets should now carry the implementation evidence checklist beside validator output, fixture references, changelog or release-note links, compatibility notes, and an owner or contact record before support language widens.
  • Support-claim effect: the adoption kit and conformance pack now publish a reviewable checklist for moving from first proof to launch evidence without presenting that evidence as certification, badge, or endorsement.
  • Reference paths: Adoption Kit, Conformance Pack, Roadmap, Changelog, and News.

2026-04-24 | Validator normalization mode release

Change type: Additive conformance and compact-transfer hardening.

  • Affected records: Validator, API Reference, Conformance Pack, Standards Fit, Roadmap, examples, field registry, OpenAPI, and the public UAIX REST surface.
  • Migration note: the validate route now accepts keyed-json, minified-keyed-json, and keyless-json; keyless packets are expanded through the public field registry before schema and policy checks run.
  • Support-claim effect: compact keyless transfer now has validator-backed expansion evidence, while alias maps and binary envelopes remain planned or research-track until public fixtures and route behavior exist.
  • Reference paths: Validator, API Reference, Conformance Pack, Roadmap, and Changelog.

2026-04-24 | Contact review and standards-fit page release

Change type: Additive public-operating and specification-boundary expansion.

  • Affected records: Contact and Review, Standards Fit, References and Contributors, Governance, Roadmap, launch audits, catalog discovery, and zh-CN localized page bodies.
  • Migration note: use the dedicated contact-and-review path for contributor packets and change proposals, and use the standards-fit path when explaining A2A, MCP, OpenAPI, JSON Schema, DID/VC, Trace Context, compact transfer, and normalization boundaries.
  • Support-claim effect: public operating and standards-fit guidance is now a page-level launch surface instead of only a roadmap item, while issue trackers, broad governance rosters, alias maps, binary envelopes, SDKs, and certification remain future work until evidence is published.
  • Reference paths: Contact and Review, Standards Fit, Roadmap, Changelog, and News.

2026-04-24 | Public roadmap and interoperability route release

Change type: Additive public-operating-layer and machine-readable guidance expansion.

  • Affected records: Roadmap, API Reference, Conformance Pack, the public UAIX REST surface, homepage navigation, and canonical roadmap guidance.
  • Migration note: use the published roadmap page and /wp-json/uaix/v1/roadmap as the current forward-plan handoff instead of reconstructing priorities from older research notes.
  • Support-claim effect: future-facing interoperability, compact-transfer, normalization, conformance, and developer-handoff ideas now have a public boundary that separates current support, next work, planned work, and research-track ideas.
  • Reference paths: Roadmap, API Reference, Conformance Pack, Changelog, and News.

2026-04-23 | UAI-1 specification fit-and-proof update

Change type: Additive specification-page reframe for launch readers and implementers.

  • Affected records: UAI-1, Specification, Schemas, Examples, Validator, API Reference, Adoption Kit, and Conformance Pack.
  • Migration note: the UAI-1 page now leads with fit, boundary, proof path, operating surfaces, and launch-support links so readers can move from specification text into current public evidence more quickly. Read the page as the main contract and launch decision surface rather than as a prose-only reference.
  • Support-claim effect: implementers can now move from the written contract into schemas, examples, validation, route guidance, and release evidence with less reconstruction work, which reduces the risk of overstating support from partial reading.
  • Reference paths: UAI-1, Schemas, Examples, Validator, API Reference, Adoption Kit, Conformance Pack, and the News archive.

2026-04-23 | Adoption kit route and page release

Change type: Additive onboarding expansion across the public launch surface.

2026-04-23 | Public security-header and trust-hardening release

Change type: Additive launch hardening across the public response and trust surface.

  • Affected records: Policy and Security, API Reference, the public UAIX REST surface, and the UAIX SEO Sweep response layer.
  • Migration note: public WordPress-rendered responses now ship with a narrow security-header baseline for framing, referrer handling, browser capability policy, and MIME-type handling. Treat HTTPS redirect, HSTS, and static-file parity as deployment follow-through rather than as already-complete app behavior.
  • Support-claim effect: the launch trust posture now has observable response hardening behind it, making it easier to verify the public machine-facing surface without overstating a broader security program.
  • Reference paths: Policy and Security, API Reference, Validator, Conformance Pack, Changelog, and News.

2026-04-23 | Dedicated governance policy-page release

Change type: Additive governance and trust-surface expansion across the launch record.

2026-04-23 | First-proof run and multi-language starter-call release

Change type: Additive onboarding expansion across the public developer path.

  • Affected records: Get Started, Examples, Tools, Validator, API Reference, and the release trail.
  • Migration note: the launch surface now publishes a first-proof runbook plus copyable curl, PowerShell, Python, and TypeScript starter requests on the public adoption pages. Use those published snippets and the validator-backed packet as the default onboarding path instead of reverse-engineering the REST surface or inventing a private SDK.
  • Support-claim effect: onboarding now points more directly to the current public contract and makes it easier to produce a reviewable first packet without overstating runtime support.
  • Reference paths: Get Started, Examples, Validator, API Reference, Conformance Pack, and Implementations.

2026-04-22 | Operating-layer, ownership, and trust-posture clarification

Change type: Additive public operating-layer clarification across the launch surface.

  • Affected records: Governance, Policy and Security, References and Contributors, the shared UAIX Core visual surfaces, and related release-trail language.
  • Migration note: use the published operating-layer matrix and handoff packet to explain what is published now, how to verify it, and what is still future work. Keep repository, contributor, ownership, and policy claims scoped to the public record until broader channels are formally published.
  • Governance effect: UAIX now makes ownership state, contributor intake, citation and discovery handoff, and trust-significant release posture easier to audit without implying a broader institution than the site currently publishes.
  • Reference paths: Governance, Policy and Security, References and Contributors, Implementations, API Reference, Conformance Pack, and News.

2026-04-22 | API reference, conformance pack, and policy surface release

Change type: Additive launch-support expansion across the public record.

2026-04-22 | Developer onramp and protocol-fit clarification

Change type: Additive public-entry and onboarding clarification across the site.

  • Affected records: Home, Get Started, UAI-1, Governance, References and Contributors, and Press.
  • Migration note: describe UAI-1 as the public envelope, trust, and evidence layer that can sit above MCP, A2A, and runtime-specific tooling, and use the published pages, machine-readable routes, examples, and validator as the current developer kit.
  • Governance effect: UAIX now states more directly what is published today, what is still future work, and how to explain the current single-publisher public record without overstating maturity.
  • Reference paths: Home, Get Started, UAI-1, Governance, References and Contributors, Press, and News.

2026-04-22 | Transport, trust, error, and conformance surface release

Change type: Additive operating-surface release across the public UAI-1 record.

  • Affected records: Specification, UAI-1, Tools, Validator, the UAIX core REST surface, capability and conformance examples, and related metadata.
  • Migration note: the public record now publishes transport bindings, trust channels, an error registry, and conformance levels. Treat these records as part of the live interoperability and support-claim surface instead of as optional commentary.
  • Support-claim effect: teams can now describe transport fit, trust posture, typed failures, and achieved conformance level with more precision when they publish release evidence.
  • Reference paths: UAI-1, Tools, Validator, Examples, Implementations, and the News archive.

2026-04-22 | Protocol contract, field registry, and async workflow release

Change type: Additive and corrective protocol expansion across the public record and machine-readable artifacts.

  • Affected records: Specification, UAI-1, Schemas, Registry, Examples, Tools, Validator, the UAIX core REST surface, and related metadata.
  • Migration note: the public contract now publishes a richer shared envelope, a field registry for keyed-to-keyless order, typed problem-style errors, validator-backed policy checks, and a dedicated uai.task.status.v1 profile for async workflow visibility. Treat these records as the new current baseline when evaluating compatibility.
  • Governance effect: UAIX now states more clearly that UAI-1 is the public exchange and release-record layer that can sit beside orchestration, tool, and trust systems without trying to replace every adjacent protocol.
  • Reference paths: UAI-1, Schemas, Registry, Examples, Validator, Implementations, and the News archive.

2026-04-22 | Endpoint and packaged artifact guidance update

Change type: Additive implementation-surface clarification across the site.

2026-04-21 | Homepage orientation and trust-surface update

Change type: Additive public-entry-surface clarification across the site.

  • Affected records: Home, the front-page launch surface, and related orientation language.
  • Migration note: use the homepage as the short public summary of the current trust posture, published support boundary, and first-read path into the deeper record rather than treating it as a generic brochure lead-in.
  • Governance effect: UAIX now makes the front door say more directly what the deeper record already supports, which reduces onboarding ambiguity without widening the published support boundary.
  • Reference paths: Home, Get Started, Implementations, Governance, and News.

2026-04-21 | Policy and trust-surface posture update

Change type: Additive governance and trust-surface clarification across the site.

  • Affected records: Governance, References and Contributors, About, Press, and related release-note language.
  • Migration note: read privacy, accessibility, and analytics posture as governance-led and release-trail-led on the current launch surface, and do not infer standalone policy programs or broader institutional disclosures that have not yet been published.
  • Governance effect: UAIX now states more concretely how policy-significant changes should be described, reviewed, and attached to the public release trail before they are treated as current truth.
  • Reference paths: Governance, References and Contributors, About, Press, and News.

2026-04-21 | Release readiness and support-claim guidance update

Change type: Additive adoption and trust-surface clarification across the site.

2026-04-21 | Technical record map update

Change type: Additive technical-orientation clarification across the site.

  • Affected records: Specification, UAI-1, Schemas, Registry, Examples, and related release-note language.
  • Migration note: use the published profile-family map and compatibility cues when moving from normative reading into schemas, registry resolution, fixtures, and validator-backed evidence, and keep those records aligned rather than treating them as separate references.
  • Governance effect: UAIX now makes the current technical stack easier to reconstruct from the public record, which reduces adoption ambiguity without changing validator behavior, routes, or profile support boundaries.
  • Reference paths: Specification, UAI-1, Schemas, Registry, Examples, and News.

2026-04-21 | Proof packet and roadmap signal update

Change type: Additive onboarding and participation-surface clarification across the site.

  • Affected records: Get Started, Tools, Governance, References and Contributors, and related release-note language.
  • Migration note: use the first public proof run and roadmap-signal guidance when assembling a reusable adoption packet or interpreting current priorities, and treat the published governance and release records as the roadmap until a standalone roadmap or contributor surface is explicitly published.
  • Governance effect: UAIX now makes the shortest path from first validation to public participation easier to reconstruct from the published record without implying issue trackers, contact channels, or ecosystem programs that are not yet public.
  • Reference paths: Get Started, Tools, Governance, References and Contributors, and News.

2026-04-21 | Evaluation and maturity guidance update

Change type: Additive public-orientation clarification across the site.

  • Affected records: Get Started, About, Press, and related release-note language.
  • Migration note: use the published evaluation checklist and maturity framing when assessing current readiness or describing UAIX to third parties, and treat unpublished contact, governance, policy, and runtime surfaces as future work unless they are explicitly published.
  • Governance effect: UAIX now distinguishes current public infrastructure from planned growth infrastructure more directly, which makes current readiness easier to cite without overstating institutional completeness.
  • Reference paths: Get Started, About, Press, and News.

2026-04-21 | Operating-layer and ownership clarity update

Change type: Additive public-operating-layer clarification across the site.

  • Affected records: Governance, References and Contributors, Implementations, and related release-note language.
  • Migration note: treat the current public operating layer as a combination of named attribution, aligned canonical records, validator or implementation evidence, and the release trail rather than as a broader published contact or governance program.
  • Governance effect: UAIX now states more concretely where current ownership is published, how release decisions become public truth, and what future implementation tracks must publish before they should be treated as supported.
  • Reference paths: Governance, References and Contributors, Implementations, and News.

2026-04-21 | Program model and adoption-kit assembly clarification

Change type: Additive public-operating-model clarification across the site.

  • Affected records: About, Get Started, Implementations, News, and related release-note language.
  • Migration note: treat UAIX’s current public work as a record-family and implementation-track surface, not as an events or membership program, and assemble the current adoption kit from the published record until a standalone download is explicitly published.
  • Governance effect: UAIX now states more directly how readers should understand the current public operating layer and where adoption packaging already exists today.
  • Reference paths: About, Get Started, Implementations, News, and References and Contributors.

2026-04-21 | Implementation scope and release-archive clarification

Change type: Additive onboarding and release-posture clarification across the site.

  • Affected records: Get Started, Implementations, News, and related release-note language.
  • Migration note: treat the WordPress Publication Track and .NET Bridge Track as the only current public implementation tracks, use the portable record when evaluating other environments, and read the news archive as a release-note-led public timeline rather than a broader community channel.
  • Governance effect: UAIX now states more directly where current public implementation support stops and where future ecosystem work would need new published records before it counts as public support.
  • Reference paths: Implementations, News, References and Contributors, and Governance.

2026-04-21 | Conformance packet and regression guidance clarification

Change type: Additive conformance-evidence clarification across the site.

  • Affected records: Implementations, Tools, Validator, Governance, and related release-note language.
  • Migration note: keep exported validator results, profile and schema references, fixture baselines, and release links together as a reusable public conformance packet, and do not present that packet as a formal certification badge or endorsement.
  • Governance effect: UAIX now states more directly that repeatable conformance evidence and regression-ready fixtures are part of the current trust surface even though a broader formal assurance program remains future work.
  • Reference paths: Implementations, Tools, Validator, Governance, and News.

2026-04-21 | Use-case and positioning guidance clarification

Change type: Additive public orientation and outward-facing language clarification across the site.

  • Affected records: About, References and Contributors, Press, and related release-note language.
  • Migration note: use the published practical use cases and positioning guardrails when describing UAIX to implementers, researchers, press, and evaluators, and do not imply unpublished partner, contact, or governance structures.
  • Governance effect: UAIX now makes the public use-case map and outward-facing limits easier to cite without changing normative behavior or route structure.
  • Reference paths: About, References and Contributors, Press, and News.

2026-04-21 | Role paths and public policy posture clarification

Change type: Additive public orientation and governance clarification across the site.

  • Affected records: Get Started, Governance, References and Contributors, and related release-note language.
  • Migration note: use the role-based reading paths when onboarding implementers, tool builders, reviewers, and public readers, and treat privacy, accessibility, and analytics pages as planned governance surfaces until they are explicitly published.
  • Governance effect: UAIX now states more directly that participation is documentation-led and that policy posture should travel through the same public release trail as the rest of the trust surface.
  • Reference paths: Governance, References and Contributors, News, and Implementations.

2026-04-21 | Adoption packet and sitemap surface clarification

Change type: Additive onboarding and discovery clarification across the site.

  • Affected records: Implementations, Tools, the root and locale sitemap surfaces, and related launch-audit coverage.
  • Migration note: keep the first-release packet tied to UAI-1, schemas, registry entries, examples, validator evidence, discovery manifests, and sitemap routes, and keep both root and locale-prefixed sitemap surfaces live in release QA.
  • Discovery effect: UAIX now states more directly that /sitemap.xml and /sitemap.html are the durable root discovery surfaces while locale-prefixed sitemap routes should continue to resolve the same public inventory for localized readers and tooling.
  • Reference paths: Implementations, Tools, References and Contributors, and News.

2026-04-21 | Governance, contributor, and validator workflow clarification

Change type: Additive public operating-layer clarification across the site.

  • Affected records: Governance, References and Contributors, Validator, the machine-readable discovery guidance, and related release-trail language.
  • Migration note: use the Validator page for the human-facing workflow, treat the validate REST route as a machine-facing JSON POST endpoint, and use Governance plus References and Contributors as the current public handoff path for contributor and citation context.
  • Governance effect: UAIX now states more explicitly that trust infrastructure, public handoff paths, and visible review posture are part of the launch-surface operating layer.
  • Reference paths: Governance, References and Contributors, Validator, Implementations, and News.

2026-04-20 | Terminology and implementation-track alignment

Change type: Corrective public terminology and naming alignment across the site.

  • Affected records: homepage copy, Get Started, About, References and Contributors, Implementations, track labels, Press language, and related public release notes.
  • Migration note: cite UAIX as the website and publication venue, UAI as the standard family, UAI-1 as the current release, and the WordPress Publication Track and .NET Bridge Track as the current public implementation-track names.
  • Governance effect: the public wording now tracks the canonical terminology model more closely, reducing ambiguity without changing routes or validator behavior.
  • Reference paths: About, References and Contributors, Implementations, Press, and News.

2026-04-20 | Authority, validator, discovery, and safety rollout

Change type: Additive standards-positioning update across the public site and runtime.

  • Affected records: homepage, About, Specification, UAI-1, Schemas, Examples, Tools, Validator, Governance, Press metadata, the public news archive, and the machine-readable discovery surface.
  • Migration note: implementers should align exchanges with published profile declarations, schema checks, provenance fields, integrity metadata, downloadable validation records, and the current discovery manifest before deployment.
  • Governance effect: UAIX now states more directly that authority is earned through public review, validator tooling, machine-readable discovery, and auditable implementation evidence.
  • Reference paths: About, Specification, UAI-1, Validator, Governance, and News.

2026-04-19 | Public standards site launch

Change type: Initial public publication release.

  • Affected records: primary UAIX route structure, specification pages, governance pages, press resources, implementation packaging, and the public news archive.
  • Migration note: use clean locale-prefixed public paths rather than query-string routes when linking or citing public UAIX material.
  • Reference paths: Home, UAI-1, WordPress Publication Track, Press, and News.

How this log pairs with other public pages

  • Use News when a changelog entry also needs a public-readable summary.
  • Use Implementations when a change affects packaging, runtime evidence, or deployment posture.
  • Use References and Contributors when citation, discovery, and attribution links should travel with the release record.
  • Use Press when the change also needs approved public language.

What every future entry should capture

  • Release date and affected record family.
  • Whether the change is additive, corrective, policy-oriented, or breaking.
  • Migration notes for implementations, validators, discovery files, and public references.
  • Links back to the canonical documents that were updated.
