docs: make kaefa README product-first and license-aware

[seonghobae]

Outcome

Consolidate kaefa's current methodological ADR work with a product-first repository landing on the existing authoritative documentation branch, without changing R runtime behavior.

• keep ADR 0001-0006 and the verified methodological source index;
• replace the stale README opening with a concise AEFA/IRT product responsibility, supported workflow, architecture boundary, source-evaluation path, Shiny/remote boundaries, maturity, and documentation navigation;
• update both README.Rmd and generated README.md together;
• remove historical seonghobae/kaefa install/CI links, Travis/AppVeyor status surfaces, changelog-style “New Feature” copy, and unsourced runtime/sizing estimates from the customer-facing landing;
• preserve the exact-cased DeepWiki entry;
• surface the repository's actual GPL-family commercial-intake blocker instead of presenting the package as commercially cleared.

Product / scientific boundary

kaefa remains an R package for automated exploratory factor/IRT model search. aefa() coordinates candidate search and engineAEFA() performs lower-level estimation; the current numerical estimation boundary is mirt. The package also contains the optional Shiny surface launchAEFA() and remote-host initialization through aefaInit().

The README now preserves the explicit productization boundaries already documented in ARCHITECTURE.md: kaefa-core, kaefa-studio, and a future kaefa-runner deployment boundary. It does not promote the future runner into a separately released product or turn exploratory search into confirmatory/scientific-validity evidence.

Source metadata is 0.1.428; the GitHub release inventory is currently empty. The README therefore does not treat a source version, historical badge, or passing development check as immutable release/support evidence.

Commercial licensing due diligence

Fresh repository/package inspection found a material policy blocker:

• DESCRIPTION declares kaefa itself as GPL-3;
• there is no root Apache-2.0/MIT LICENSE file;
• DESCRIPTION directly imports mirt (>= 1.27), a GPL-family numerical runtime used by the product's estimation/search paths;
• package metadata also names Tae-Yong Yoo as a thesis contributor (ths, ctb), so repository ownership alone is not sufficient evidence for unilateral first-party relicensing without contribution/provenance review.

Issue #83 now owns the complete first-party provenance/relicensing and GPL-family runtime/build replacement problem. Closure requires preserving the intentionally supported scientific estimands/search/recovery behavior with exact regression/recovery evidence rather than merely changing DESCRIPTION, hiding dependency-license evidence, or moving the same GPL implementation behind another process boundary.

Until #83 is resolved, kaefa is not currently cleared for ContextualWisdomLab commercial intake/distribution, and this documentation PR must not be presented as commercial-readiness evidence.

README truth repairs

The previous landing contained several stale or weak public surfaces that are removed from this branch:

• installation pointed to the historical personal repository seonghobae/kaefa;
• R-CMD-check, Travis CI, and AppVeyor badges pointed to historical personal-repository infrastructure rather than current organization evidence;
• a local-vs-remote sizing table asserted respondent/item/runtime/hardware thresholds without repository evidence;
• feature-specific implementation copy dominated the landing instead of the product job, current responsibility, and scientific evidence boundary.

Source evaluation now points to ordinary package build/check commands and explicitly delegates exact environment/check authority to current package metadata and repository workflows.

Current exact authority — 2026-09-27

• protected base recorded by GitHub: develop@5128d4867e24b5db73e6e3c8652a8dbeabd70aa0;
• exact current head: 873dc0587453002a62a6ab2a959c998361e51686;
• state: open / Ready review admission / mechanically mergeable at the latest read;
• RED contract head 703635099e43c694c048846c6c41895774727fda reproduced zero actionable fallback contacts and the unrounded RMSEA provenance rule;
• GREEN documentation blobs remain SECURITY.md@59613b8c… and docs/papers/README.md@f775ce32…; the repaired contract blob is tests/testthat/test-documentation-validation.R@7b3c4922…;
• predecessor test-suite 36241191296 reproduced 1 failed / 900 passed: the new fallback assertion passed an unsupported info= argument to expect_gt(). Exact head 873dc058… uses the compatible expect_true(length(mailto_matches) > 0, info=...) assertion without weakening the required fallback;
• the security fallback now uses a creator email already published in DESCRIPTION; no contact detail or licensing right was inferred;
• the RMSEA provenance now matches accepted ADR 0003: round(RMSEA.S_X2, 2) >= .05;
• the inline review thread is resolved; exact-head CodeRabbit and Devin commit statuses are successful, but neither is a qualifying independent approval;
• replacement exact-head test-fast 36265024932, R-CMD-check 36265024777, test-suite 36265025115, and SAST Semgrep 36265024761 are terminal GREEN; Security Scan 36265024721 and CodeQL PR 36265024913 remain queued and are not treated as GREEN;
• no qualifying independent approval exists on the current head; every predecessor-head check or review is historical.

Scope / merge boundary

Documentation plus one focused operational-documentation contract: README source/generated output, SECURITY guidance, the existing ADR/research/architecture documentation, and tests/testthat/test-documentation-validation.R. No R runtime source, package manifest, NAMESPACE, Shiny implementation, dependency graph, workflow, release, or repository setting is changed by this branch.

Ready is review admission, not merge approval or commercial clearance. This documentation PR may integrate only when its unchanged exact head has terminal required Checks, zero valid unresolved findings, a qualifying independent approval, current ancestry/mergeability, and ordinary protected governance. Issue #83 remains the separate product release/commercial-intake gate; merging accurate disclosure does not resolve or bypass it. Do not tag, release, self-approve, fabricate evidence, or use administrator bypass.

Priority: ➖ Normal

Estimated code review effort: 2 (Simple) | ~12 minutes

Change: Other

Merge Risk: ⚪ Minimal · up to 873dc

The documented RMSEA decision rule matches the package behavior, and the earlier documentation discrepancy is corrected. No concrete merge risk remains in the reviewed changes.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 873dc

The updated guidance keeps private reporting as the first option and names a fallback contact already published for the package. No misrouting is evident, but the documentation cannot establish that either destination is operational or who can access the fallback mailbox.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The affected exposure is the handling of externally submitted vulnerability reports through GitHub advisories or email, not an expanded package execution or privileged application entrypoint.

Trust Boundaries and Controls

• observed — The instructions retain private advisory reporting as the primary route and prohibit premature public disclosure. The fallback names an existing package contact, but repository evidence does not establish mailbox access controls or whether the channels are monitored.

Hardening Proposals

• proposed — Confirm that the organization advisory destination and fallback mailbox accept private reports and are monitored by the intended maintainers; the documentation test cannot verify those operational properties.

Public-surface coordination: #82 now owns the existing gh-pages branch refresh and preserves the custom CNAME. This draft already owns both README.Rmd and generated README.md, so please keep root README public-surface cleanup in this writer rather than opening a duplicate README PR. Before this branch leaves Draft, add exactly one [![Ask DeepWiki](https://deepwiki.com/badge.svg)](https://deepwiki.com/ContextualWisdomLab/kaefa) badge to the appropriate badge area in both source/generated README, and normalize customer-facing GitHub install/CI links that still point at the pre-organization seonghobae/kaefa namespace. Preserve the RMarkdown source-of-truth rule and regenerate README.md coherently rather than editing only the generated file. #82 intentionally does not compete for those files.

[seonghobae]

Public-surface coordination update: this existing README writer now also carries the exact Ask DeepWiki badge in both README.Rmd (source of truth) and generated README.md, linked to https://deepwiki.com/ContextualWisdomLab/kaefa. I kept the PR Draft and did not broaden it into Pages/settings work; gh-pages public-site refresh #82 was handled independently and is now merged. Preserve the generated README/source pairing when this branch is refreshed.

[seonghobae]

Public-surface/security follow-up on exact head 402b9f4c7f00c297ed059e01dadc4e62a30660bb: SECURITY.md still pointed reporters to the historical seonghobae/kaefa private-advisory URL even though this documentation lane has already migrated the README to the ContextualWisdomLab repository. The branch now uses the exact organization repository advisory path, removes public issue/PR/discussion disclosure as a fallback, and gives a private-maintainer fallback only when the repository feature is unavailable. No R runtime, dependency, package license, or scientific claim changed. All predecessor-head hosted evidence is historical after this documentation commit; #83 remains the commercial-license/provenance blocker.

Current-head review repair record (2026-09-26)

• RED 703635099e43c694c048846c6c41895774727fda: the new operational documentation contract found no actionable mailto: fallback in SECURITY.md and no canonical rounded RMSEA expression in formula provenance.
• GREEN 509c9275215ff9f05615e826f1873cd16035dbff: SECURITY.md now uses a creator address already published in DESCRIPTION; docs/papers/README.md now matches accepted ADR 0003 with round(RMSEA.S_X2, 2) >= .05.
• Remote exact-head contract evidence: fallback count 1, fallback address present in DESCRIPTION, canonical formula present, stale unrounded formula absent.
• Remote blobs: SECURITY.md@59613b8cd8b30a4f51d5ebd8297dd78bf9f0305f, docs/papers/README.md@f775ce32bac7e2fbbd24c347d05a5c9289c16d51, tests/testthat/test-documentation-validation.R@fbbb5767c4c557e30753bc4b39cd4762582b7391.
• The inline security thread is resolved. CodeRabbit's current-head delta review and six hosted workflows are still in progress/queued, so this PR remains Draft. No predecessor-head GREEN or review is being reused.

2026-09-26 metadata/publication reconciliation evidence:

• exact source head remains 509c9275215ff9f05615e826f1873cd16035dbff; protected develop@5128d4867e24b5db73e6e3c8652a8dbeabd70aa0
• compare is ahead 11 / behind 0 and mechanically mergeable
• the head README carries exactly the ContextualWisdomLab/kaefa DeepWiki target; protected develop does not yet carry it
• existing Pages is independently sourced from protected gh-pages@bbac3d41eb9ef2762fe21ecf6a2ee1989bb6669f, whose root contains index.md and CNAME=kaefa.seonghobae.me
• all six exact-head repository workflows remain queued; unresolved review threads are 0 and qualifying independent approvals are 0
• the conflicting type: docs alias was removed; canonical documentation / priority: medium / status: draft remains
• central desired-state owner .github#2110 now preserves gh-pages:/ through an exact pages_branch contract

Keep Draft. The custom domain could not be reached from the verification environment, so no live HTTP publication, settings convergence, or merge readiness is claimed.
