 ## 9. Future Considerations / Roadmap
 
-- Add non-interactive regression fixtures for historically trusted
-  FIPC results.
+- Maintain non-interactive regression fixtures for historically trusted
+  FIPC results and extend them before behavior-changing calibration work.
 - Reduce interactive prompts in `autoFIPC()` for automation friendliness.
 - Evaluate migration path from historical `packrat/` to a modern
   lock workflow.

+# Regression Fixture Replacement Note
+
+## Decision
+
+PR #87 should be replaced rather than repaired in place.
+
+The markdown failure in PR #87 is mechanical, but the IPD test asserts that a
+specific drifted anchor must be removed from `IPDCommonItemList`. Current CI
+evidence showed that `autoFIPC()` retained that anchor while still exercising
+the IPD filtering path. Changing `R/aFIPC.R` to satisfy that assertion would be
+an algorithmic behavior change without maintainer-approved regression evidence.
+
+## Replacement Scope
+
+This branch keeps the regression lane additive:
+
+- fixture-backed prior-update coverage for free-mean versus fixed-normal
+  linking;
+- fixture-backed IPD coverage that verifies filtered anchors are the anchors
+  subsequently fixed in the linked model;
+- no changes to `R/aFIPC.R` numerical behavior;
+- no Figma Code Connect usage.
+
+Exact drift classification for synthetic IPD anchors remains a follow-up
+algorithmic task and should not be folded into duplicate queue triage.

- mirt 추정(MHRM)이 실패할 때 발생하던 `while(!exists('...'))` 무한 루프 문제 해결
- 무한 루프 방지를 위해 최대 재시도 횟수(max_retries = 3) 제한 추가
- 3회 재시도 초과 시 `stop()`을 호출하여 안전하게 에러를 발생시키도록(fail-secure) 처리
- `tests/testthat/test-MHRM-failure-dos.R` 테스트 케이스 추가를 통해 재시도 제한 로직 검증
- .jules/sentinel.md 에 관련 보안 학습 내용 추가

+## 2024-06-30 - 추정 실패 시 무한 재시도로 인한 리소스 고갈(DoS) 취약점
+**Vulnerability:** 데이터 처리 과정 중 모델 추정이 실패했을 때(예: `mirt` 패키지의 MHRM 알고리즘을 이용한 oldFormModel, newFormModel 추정), 변수가 성공적으로 생성될 때까지 `while(!exists('oldFormModel'))`과 같은 탈출 조건(exit condition)이 없는 무한 루프가 코드 내에 존재했습니다.
+**Learning:** 실패 시 무한 루프는 자동화된 환경(CI/CD, 묶음 처리 서버 등)에서 작업이 절대 끝나지 않고 CPU와 메모리 등 시스템 리소스를 계속 점유하게 만들어 서비스 거부(DoS) 상태를 유발합니다. 외부 라이브러리(패키지) 호출 실패를 무한정 재시도하는 것은 매우 위험합니다.
+**Prevention:**
+1. 어떠한 형태의 재시도 루프든 간에 반드시 최대 재시도 횟수(`max_retries`) 제한을 두어 무한 루프에 빠지지 않도록 방어적인 코드를 작성해야 합니다.
+2. 최대 재시도 횟수에 도달했을 때에는 `stop()` 함수 등을 사용해 명시적인 예외를 발생시키고 안전하게 실패하도록(fail-secure) 처리해야 합니다.

+# aFIPC Maintenance Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use
+> superpowers:subagent-driven-development (recommended) or
+> superpowers:executing-plans to implement this plan task-by-task. Steps use
+> checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Turn the aFIPC maintenance package into a queue-cleaning workflow
+that preserves `autoFIPC()` numerical behavior while reducing duplicate PRs.
+
+**Architecture:** Use live GitHub evidence as the control plane, Markdown docs
+as the durable handoff, and FigJam as the visual planning surface. Algorithmic
+changes are allowed only after deterministic regression evidence is present.
+
+**Tech Stack:** R package, `mirt`, `testthat`, GitHub CLI, GitHub Actions,
+Figma FigJam, Markdown.
+
+## Global Constraints
+
+- Figma Code Connect is forbidden.
+- Do not call `get_code_connect_map`, `get_code_connect_suggestions`,
+  `get_context_for_code_connect`, or the `figma-code-connect` skill.
+- Do not change `R/aFIPC.R` numerical behavior without regression evidence.
+- Keep algorithmic, security, performance, and documentation work separate.
+- Prefer closing duplicated bot PRs over stacking overlapping changes.
+- Refresh live GitHub state before executing any PR decision.
+- If structural symbol tracing is needed, ask before running
+  `codegraph init -i` because `.codegraph/` is absent.
+
+---
+
+### Task 1: Refresh The Queue Evidence
+
+**Files:**
+
+- Read: `AGENTS.md`
+- Read: `ARCHITECTURE.md`
+- Read: `README.md`
+- Read: `docs/superpowers/specs/2026-07-02-afipc-maintenance-design.md`
+- Modify: none
+
+**Interfaces:**
+
+- Consumes: GitHub repository `ContextualWisdomLab/aFIPC`
+- Produces: current PR/issue evidence for Tasks 2-5
+
+- [ ] **Step 1: Confirm the working branch**
+
+```bash
+git status --short --branch
+```
+
+Expected: branch is not `master`; for this package it should be
+`codex/afipc-maintenance-planning` or another dedicated work branch.
+
+- [ ] **Step 2: Confirm repository metadata**
+
+```bash
+gh repo view ContextualWisdomLab/aFIPC \
+  --json nameWithOwner,defaultBranchRef,isPrivate,visibility,primaryLanguage,url
+```
+
+Expected: `defaultBranchRef.name` is `master` and `visibility` is `PUBLIC`.
+
+- [ ] **Step 3: Capture compact PR state**
+
+```bash
+fields="number,title,updatedAt,headRefName"
+fields="$fields,mergeStateStatus,reviewDecision"
+fields="$fields,statusCheckRollup,url"
+gh pr list --repo ContextualWisdomLab/aFIPC --state open --limit 100 \
+  --json "$fields" \
+  | jq -r '.[] | {
+      number,
+      title,
+      headRefName,
+      updatedAt,
+      mergeStateStatus,
+      reviewDecision,
+      url,
+      failingChecks: ([.statusCheckRollup[]? |
+        select((.conclusion // "") == "FAILURE") | .name] | join(",")),
+      pendingChecks: ([.statusCheckRollup[]? |
+        select((.status // "") != "COMPLETED") | .name] | join(",")),
+      successCount: ([.statusCheckRollup[]? |
+        select((.conclusion // "") == "SUCCESS")] | length)
+    } | [
+      .number,
+      .mergeStateStatus,
+      .reviewDecision,
+      .successCount,
+      .failingChecks,
+      .pendingChecks,
+      .updatedAt,
+      .headRefName,
+      .title,
+      .url
+    ] | @tsv'
+```
+
+Expected: one line per open PR with failing checks visible. If the PR count
+differs from the spec, update the execution notes before making decisions.
+
+- [ ] **Step 4: Capture compact issue state**
+
+```bash
+gh issue list --repo ContextualWisdomLab/aFIPC --state open --limit 100 \
+  --json number,title,updatedAt,labels,url
+```
+
+Expected: issue #44, #8, #7, and #6 are present unless live state changed.
+
+- [ ] **Step 5: Commit only if evidence docs changed**
+
+If Task 1 updates docs, commit those changes:
+
+```bash
+git add docs/superpowers
+git commit -m "docs: record aFIPC maintenance planning evidence"
+```
+
+Expected: commit succeeds. Skip this step if no files changed.
+
+### Task 2: Repair Or Replace Regression Fixture Coverage
+
+**Files:**
+
+- Read: `tests/testthat/test-fixed-parameter-calibration.R`
+- Read: `tests/testthat/test-package-api.R`
+- Candidate modify: files from PR #87 after inspecting its diff
+- Candidate create: `tests/testthat/fixtures/*.R`
+
+**Interfaces:**
+
+- Consumes: PR #87 or a replacement branch
+- Produces: deterministic coverage for prior-update behavior and IPD anchor
+  filtering
+
+- [ ] **Step 1: Inspect PR #87**
+
+```bash
+gh pr view 87 --repo ContextualWisdomLab/aFIPC \
+  --json headRefOid,mergeStateStatus,reviewDecision,statusCheckRollup,files,url
+```
+
+Expected: current failing checks and changed files are visible.
+
+- [ ] **Step 2: Fetch the PR patch**
+
+```bash
+gh pr diff 87 --repo ContextualWisdomLab/aFIPC > /tmp/afipc-pr-87.diff
+```
+
+Expected: `/tmp/afipc-pr-87.diff` exists and includes only test/docs changes or
+clearly justified helper changes.
+
+- [ ] **Step 3: Decide fix versus replacement**
+
+Use this rule:
+
+```text
+If PR #87 changes only tests/docs and failures are mechanical, repair it.
+If PR #87 changes algorithm behavior or has unclear generated code, recreate a
+smaller regression-only branch and close #87 as superseded.
+```
+
+Expected: one written decision in the PR comment or local execution notes.
+
+- [ ] **Step 4: Run local package tests**
+
+```bash
+R_PROFILE_USER=/dev/null Rscript -e 'testthat::test_dir("tests/testthat")'
+```
+
+Expected: PASS. If `mirt` is unavailable locally, record the dependency gap and
+use CI as the authoritative execution environment.
+
+- [ ] **Step 5: Run package check**
+
+```bash
+R_PROFILE_USER=/dev/null Rscript -e \
+'rcmdcheck::rcmdcheck(args = c("--no-manual", "--as-cran"), error_on = "error")'
+```
+
+Expected: PASS or a documented environment-only failure that CI does not
+reproduce.
+
+- [ ] **Step 6: Commit the regression lane result**
+
+```bash
+git add tests docs
+git commit -m "test: add aFIPC numerical regression fixtures"
+```
+
+Expected: one commit containing only regression evidence and related docs.
+
+### Task 3: Select One Sentinel Security Fix
+
+**Files:**
+
+- Read: `R/aFIPC.R`
+- Read: `tests/testthat/test-autoFIPC.R`
+- Candidate modify: only the selected Sentinel branch changes
+
+**Interfaces:**
+
+- Consumes: Sentinel PRs #88, #86, #83, #82, #77, #74, #71
+- Produces: one security fix path and a close list for duplicates
+
+- [ ] **Step 1: Compare active Sentinel PRs**
+
+```bash
+for pr in 88 86 83 82 77 74 71; do
+  gh pr view "$pr" --repo ContextualWisdomLab/aFIPC \
+    --json number,title,mergeStateStatus,reviewDecision,url
+done
+```
+
+Expected: one JSON object per Sentinel PR.
+
+- [ ] **Step 2: Pick the candidate**
+
+Use this rule:
+
+```text
+Prefer a branch that is approved or has resolvable changes requested, has no
+failing required checks, and changes the fewest lines in the shared prompt or
+retry path. Reject dirty branches unless their patch is materially better.
+```
+
+Expected: one selected PR number and a duplicate-close list.
+
+- [ ] **Step 3: Verify the selected diff**
+
+```bash
+gh pr diff SELECTED_PR --repo ContextualWisdomLab/aFIPC
+```
+
+Expected: no broad refactor, no unrelated docs churn, and no numerical model
+changes beyond bounded retry or non-interactive failure behavior.
+
+- [ ] **Step 4: Run targeted tests**
+
+```bash
+R_PROFILE_USER=/dev/null Rscript -e 'testthat::test_file("tests/testthat/test-autoFIPC.R")'
+```
+
+Expected: PASS.
+
+- [ ] **Step 5: Close duplicated Sentinel PRs after selected fix is accepted**
+
+```bash
+body="Superseded by the selected Sentinel DoS fix."
+gh pr close DUPLICATE_PR --repo ContextualWisdomLab/aFIPC \
+  --comment "$body"
+```
+
+Expected: duplicate PR closes with a clear reason. Do this only after the
+selected security fix is merged or explicitly chosen by the maintainer.
+
+### Task 4: Select One Bolt Performance Fix
+
+**Files:**
+
+- Read: `R/aFIPC.R`
+- Read: `tests/testthat/test-fixed-parameter-calibration.R`
+- Candidate modify: only the selected Bolt branch changes
+
+**Interfaces:**
+
+- Consumes: Bolt PRs #89, #85, #84, #81, #79, #76, #75, #73, #72
+- Produces: one performance fix path and a close list for duplicates
+
+- [ ] **Step 1: Compare active Bolt PRs**
+
+```bash
+for pr in 89 85 84 81 79 76 75 73 72; do
+  gh pr view "$pr" --repo ContextualWisdomLab/aFIPC \
+    --json number,title,mergeStateStatus,reviewDecision,url
+done
+```
+
+Expected: one JSON object per Bolt PR.
+
+- [ ] **Step 2: Pick the candidate**
+
+Use this rule:
+
+```text
+Prefer one measured, narrow optimization after regression fixtures pass. Reject
+dirty branches, duplicated fscores caching branches, and changes that combine
+performance with unrelated non-interactive prompt behavior.
+```
+
+Expected: one selected PR number and a duplicate-close list.
+
+- [ ] **Step 3: Verify behavior preservation**
+
+```bash
+R_PROFILE_USER=/dev/null Rscript -e 'testthat::test_file("tests/testthat/test-fixed-parameter-calibration.R")'
+```
+
+Expected: PASS and fixed common-item parameters remain equal to old-form values.
+
+- [ ] **Step 4: Run full package check**
+
+```bash
+R_PROFILE_USER=/dev/null Rscript -e \
+'rcmdcheck::rcmdcheck(args = c("--no-manual", "--as-cran"), error_on = "error")'
+```
+
+Expected: PASS.
+
+- [ ] **Step 5: Close duplicated Bolt PRs after selected fix is accepted**
+
+```bash
+body="Superseded by the selected Bolt optimization."
+gh pr close DUPLICATE_PR --repo ContextualWisdomLab/aFIPC \
+  --comment "$body"
+```
+
+Expected: duplicate PR closes with a clear reason. Do this only after the
+selected optimization is merged or explicitly chosen by the maintainer.
+
+### Task 5: Patch Maintainer Documentation
+
+**Files:**
+
+- Modify: `docs/operations/maintenance-runbook.md`
+- Modify: `.github/PULL_REQUEST_TEMPLATE.md`
+- Optional modify: `README.md`
+
+**Interfaces:**
+
+- Consumes: queue classification from Tasks 1-4
+- Produces: maintainer-facing process for duplicate PR triage and Figma link
+  retention
+
+- [ ] **Step 1: Update repository owner commands**
+
+Replace stale `seonghobae/aFIPC` command examples with
+`ContextualWisdomLab/aFIPC` where the command targets this repository.
+
+Expected: no stale owner appears in runbook command examples.
+
+- [ ] **Step 2: Add PR category checklist**
+
+Add this checklist to `.github/PULL_REQUEST_TEMPLATE.md`:
+
+```markdown
+## Change Category
+
+- [ ] Regression evidence
+- [ ] Security / DoS guardrail
+- [ ] Performance optimization
+- [ ] CI / governance
+- [ ] Documentation only
+- [ ] Other:
+```
+
+Expected: contributors must classify PR intent before review.
+
+- [ ] **Step 3: Add duplicate-close rule**
+
+Add this rule to `docs/operations/maintenance-runbook.md`:
+
+```markdown
+When multiple bot PRs touch the same `R/aFIPC.R` path for the same problem,
+choose one candidate after live checks and diff review. Close older overlapping
+PRs as superseded after the selected fix is merged or explicitly chosen.
+```
+
+Expected: maintainers have a clear close policy.
+
+- [ ] **Step 4: Add FigJam artifact location**
+
+Add the current FigJam planning link to the runbook:
+
+```markdown
+- aFIPC maintenance decision flow:
+  https://www.figma.com/board/G6GNn2sGFJ19T8uFv9EtgI
+```
+
+Expected: the non-Code-Connect visual artifact is discoverable from repo docs.
+
+- [ ] **Step 5: Validate docs**
+
+```bash
+markdownlint-cli2 \
+  README.md AGENTS.md ARCHITECTURE.md CLAUDE.md CONTRIBUTING.md \
+  .github/**/*.md docs/**/*.md
+```
+
+Expected: PASS. If `markdownlint-cli2` is missing, run
+`npx markdownlint-cli2 ...` or rely on the Code Quality workflow.
+
+- [ ] **Step 6: Commit documentation**
+
+```bash
+git add docs/operations/maintenance-runbook.md .github/PULL_REQUEST_TEMPLATE.md README.md
+git commit -m "docs: clarify aFIPC maintenance triage flow"
+```
+
+Expected: one documentation-only commit.
+
+### Task 6: Reassess Governance And Packrat Separately
+
+**Files:**
+
+- Read: `packrat/packrat.lock`
+- Read: `README.md`
+- Read: `ARCHITECTURE.md`
+- Candidate create: `docs/plans/YYYY-MM-DD-packrat-migration.md`
+
+**Interfaces:**
+
+- Consumes: PR #80 and `packrat/` size evidence
+- Produces: separate decision on governance and dependency modernization
+
+- [ ] **Step 1: Recheck PR #80**
+
+```bash
+gh pr view 80 --repo ContextualWisdomLab/aFIPC \
+  --json number,title,mergeStateStatus,reviewDecision,statusCheckRollup,url
+```
+
+Expected: confirm whether `opencode-review` still fails.
+
+- [ ] **Step 2: Measure `packrat/`**
+
+```bash
+du -sh packrat
+git ls-files 'packrat/**' | wc -l
+```
+
+Expected: current size and file count are recorded.
+
+- [ ] **Step 3: Keep `packrat/` migration separate**
+
+Use this rule:
+
+```text
+Do not remove or replace packrat in the same PR as queue triage, Sentinel,
+Bolt, or regression fixture work. Create a dedicated migration proposal with
+reproducibility rollback notes.
+```
+
+Expected: no `packrat/` deletion in the maintenance triage branch.
+
+- [ ] **Step 4: Commit only if a migration proposal is written**
+
+```bash
+git add docs/plans
+git commit -m "docs: propose packrat migration path"
+```
+
+Expected: optional docs-only commit.
+
+### Task 7: Final Verification And Handoff
+
+**Files:**
+
+- Read: `docs/superpowers/specs/2026-07-02-afipc-maintenance-design.md`
+- Read: `docs/superpowers/plans/2026-07-02-afipc-maintenance-plan.md`
+
+**Interfaces:**
+
+- Consumes: all prior task outputs
+- Produces: final maintainer handoff
+
+- [ ] **Step 1: Verify Code Connect was not used**
+
+```bash
+rg -n "get_code_connect|figma-code-connect|Code Connect" docs/superpowers
+```
+
+Expected: only prohibition text appears.
+
+- [ ] **Step 2: Verify no algorithmic code changed in this planning pass**
+
+```bash
+git diff -- R/aFIPC.R tests
+```
+
+Expected: empty diff unless the user explicitly advanced from planning into
+implementation.
+
+- [ ] **Step 3: Verify docs exist**
+
+```bash
+test -f docs/superpowers/specs/2026-07-02-afipc-maintenance-design.md
+test -f docs/superpowers/plans/2026-07-02-afipc-maintenance-plan.md
+```
+
+Expected: both commands exit with code 0.
+
+- [ ] **Step 4: Verify final git state**
+
+```bash
+git status --short --branch
+```
+
+Expected: only intentional docs changes remain, or the branch is clean after
+commits.
+
+- [ ] **Step 5: Handoff**
+
+Report:
+
+```text
+Spec path:
+docs/superpowers/specs/2026-07-02-afipc-maintenance-design.md
+
+Plan path:
+docs/superpowers/plans/2026-07-02-afipc-maintenance-plan.md
+
+FigJam:
+https://www.figma.com/board/G6GNn2sGFJ19T8uFv9EtgI
+
+Next recommended execution:
+Task 1, then Task 2, then one Sentinel candidate.

+# aFIPC Maintenance Design
+
+## Purpose
+
+Build a concrete maintenance package for `ContextualWisdomLab/aFIPC` using
+Figma, Product Design, Superpowers, Ponytail, and Data Analytics without using
+Figma Code Connect.
+
+The package exists to help maintainers decide what to do with the live PR queue
+while preserving the historical numerical behavior of `autoFIPC()`.
+
+## Current Evidence
+
+Evidence was refreshed on 2026-07-02 from the local checkout and live GitHub
+state.
+
+- Repository: `ContextualWisdomLab/aFIPC`
+- Visibility: public
+- Default branch: `master`
+- Primary runtime shape: R package with a large historical `packrat/` vendor
+  tree
+- Core algorithm file: `R/aFIPC.R`
+- Local checkout branch for this planning work:
+  `codex/afipc-maintenance-planning`
+- Open PRs: 19
+- Open issues: 4
+- Active workflows: Code Quality, CodeQL, Dependency Review, R CMD check,
+  Scorecard supply-chain security, Security Audit
+- `packrat/`: 58 MB and 1,876 tracked files
+- Non-`packrat/` tracked files: 43
+- Figma/FigJam artifact:
+  [FigJam board](https://www.figma.com/board/G6GNn2sGFJ19T8uFv9EtgI)
+
+Earlier planning observed 20 open PRs. The live refresh supersedes that count.
+
+## Non-Negotiable Constraints
+
+- Do not use Figma Code Connect.
+- Do not call `get_code_connect_map`, `get_code_connect_suggestions`,
+  `get_context_for_code_connect`, or the `figma-code-connect` skill.
+- Do not alter `autoFIPC()` numerical behavior without fixture-backed
+  regression evidence and maintainer intent.
+- Do not build a new frontend app or dashboard for this R package.
+- Keep operational, documentation, and algorithmic changes in separate PRs.
+- Prefer closing duplicated bot PRs over merging multiple branches that touch
+  the same legacy logic.
+- Treat `AGENTS.md` as the repository's operating contract.
+
+## Tool Roles
+
+### Data Analytics
+
+Use GitHub and repository evidence to classify the PR/issue queue, identify
+duplicate work, and recommend merge or close order. The analysis is based on
+live PR state, review state, failed checks, and the package risk model.
+
+### Figma
+
+Use Figma only for editable planning artifacts:
+
+- `generate_diagram` for FigJam diagrams
+- `use_figma` for future non-Code-Connect edits to Figma files
+- `get_metadata` and `get_screenshot` for future design-file inspection
+- `create_new_file` only when a new design or board is needed
+
+The current FigJam diagram is a maintenance decision flow. It shows evidence
+refresh, PR classification, regression/security/performance/governance lanes,
+validation gates, merge-or-close decisions, and queue cleanup repetition.
+
+### Product Design
+
+Audit the developer and maintainer experience rather than a product UI. The
+target surfaces are:
+
+- `README.md`
+- `ARCHITECTURE.md`
+- `AGENTS.md`
+- `CONTRIBUTING.md`
+- `docs/operations/maintenance-runbook.md`
+- `.github/PULL_REQUEST_TEMPLATE.md`
+- `.github/ISSUE_TEMPLATE/*.md`
+
+The Product Design outcome is a maintainer journey with fewer ambiguous next
+steps: how to triage PRs, when to demand regression evidence, where to document
+Figma/FigJam artifacts, and when to close duplicated bot work.
+
+### Ponytail
+
+Apply the smallest solution that works. For this repository that means:
+
+- no new app
+- no new dashboard runtime
+- no broad refactor of `R/aFIPC.R`
+- no custom analytics system
+- use GitHub state, Markdown docs, and one FigJam diagram
+- reduce work by closing duplicates and avoiding speculative abstractions
+
+### Superpowers
+
+Use a durable design spec and execution plan. The spec captures scope,
+constraints, evidence, and risks. The plan decomposes the next execution pass
+into reviewable tasks with commands and verification gates.
+
+## PR Queue Classification
+
+### Regression Lane
+
+- PR #87: fixture-backed prior-update and IPD anchor filtering coverage.
+- Current state: blocked, review required, failing `quality`, `check`, and
+  `opencode-review`.
+- Decision: highest strategic value, but not mergeable until failures are
+  diagnosed and fixed.
+- Reason: this creates the regression evidence needed before touching
+  high-risk numerical behavior.
+
+### Sentinel Security Lane
+
+- PRs: #88, #86, #83, #82, #77, #74, #71.
+- Theme: non-interactive prompt, infinite loop, retry, and DoS handling around
+  `autoFIPC()`.
+- Current best candidates: #86 and #83 are approved but behind; #88 has all
+  key checks passing but has changes requested.
+- Dirty or stale duplicates: #82, #77, #74, #71.
+- Decision: compare the cleanest approved/current Sentinel branch against
+  `master`, keep one implementation, close or supersede older duplicates.
+
+### Bolt Performance Lane
+
+- PRs: #89, #85, #84, #81, #79, #76, #75, #73, #72.
+- Theme: repeated `fscores()` caching, item lookup caching, vectorized common
+  item extraction, and string matching changes.
+- Current best candidates: #85 and #84 are approved but behind; #89 is newer
+  and checks pass but has changes requested.
+- Dirty or stale duplicates: #81, #79, #76, #75, #73, #72.
+- Decision: merge at most one narrowly measured optimization after regression
+  coverage is in place. Close overlapping dirty branches.
+
+### Product/Palette Lane
+
+- PR #70: Palette/test coverage/non-interactive behavior.
+- Current state: blocked, changes requested, checks passing.
+- Decision: do not treat this as a UI improvement, because the repository has
+  no frontend product. Extract any useful test coverage only if it is not
+  already covered by the regression lane.
+
+### Governance Lane
+
+- PR #80: OpenSSF readiness baseline.
+- Current state: behind, review required, failing `opencode-review`.
+- Decision: lower priority than regression and security work. Re-evaluate after
+  queue pressure is reduced.
+
+### Dependabot Lane
+
+- No open Dependabot PRs were found in the refreshed queue.
+- Recent default-branch commits show Dependabot updates already merged.
+
+## Open Issue Alignment
+
+- Issue #44: 100% `testthat()` coverage. This should not drive broad tests for
+  their own sake. Use it to prioritize regression tests around `autoFIPC()`.
+- Issue #8: maintainer operations cadence. The runbook and FigJam flow support
+  this directly.
+- Issue #7: numerical regression safety net. PR #87 is the first lane to fix.
+- Issue #6: CI gates and Dependabot queue. Current workflows are active, but
+  PR queue pressure remains unresolved.
+
+## Product Design Audit Findings
+
+### Strengths
+
+- `AGENTS.md` clearly prioritizes numerical stability and small changes.
+- `README.md` names the package status and local check command.
+- `ARCHITECTURE.md` identifies `R/aFIPC.R` as the high-risk core.
+- The PR template asks for behavioral impact and regression evidence.
+- Issue templates ask for reproduction and numerical behavior notes.
+
+### Gaps
+
+- The maintenance runbook still uses `seonghobae/aFIPC` in several commands,
+  while the active target is `ContextualWisdomLab/aFIPC`.
+- The runbook lists weekly commands but does not explain duplicate bot PR
+  grouping, superseding, or close criteria.
+- There is no durable place to link Figma/FigJam maintenance boards.
+- The PR template does not ask contributors to classify changes as
+  regression, security, performance, governance, or documentation.
+- CodeGraph is not initialized in this checkout, so structural symbol queries
+  are unavailable until the user approves `codegraph init -i`.
+
+## Ponytail Simplification Findings
+
+- The largest removable complexity candidate is `packrat/`, but removal is not
+  a first step because it affects reproducibility and historical dependency
+  expectations.
+- The fastest queue reduction is not code modification. It is duplicate PR
+  consolidation.
+- The single high-risk file, `R/aFIPC.R`, should not be split until regression
+  fixture coverage exists and a narrower extraction target is proven.
+- Governance docs should be patched only where they reduce maintainer
+  ambiguity. Do not add a new process framework.
+
+## Recommended Decision Order
+
+1. Fix or replace PR #87 so prior-update and IPD anchor behavior are covered by
+   deterministic regression tests.
+2. Select one Sentinel DoS branch, rebase it, verify `R CMD check`, and close
+   older overlapping Sentinel PRs as superseded.
+3. Select one Bolt optimization branch only after regression coverage passes.
+4. Patch the maintenance runbook and PR template for queue classification and
+   duplicate-close policy.
+5. Revisit OpenSSF/governance PR #80 after the algorithm-adjacent queue is
+   smaller.
+6. Defer `packrat/` migration to a dedicated proposal with reproducibility
+   rollback notes.
+
+## Figma/FigJam Deliverables
+
+Created:
+
+- `aFIPC Maintenance Decision Flow`
+- URL: [FigJam board](https://www.figma.com/board/G6GNn2sGFJ19T8uFv9EtgI)
+- Method: Figma `generate_diagram`
+- Code Connect: not used
+
+Candidate future boards:
+
+- `autoFIPC()` calibration and linking flow
+- IPD anchor filtering flow
+- CI/security workflow dependency map
+- PR queue swimlane board
+
+## Risks
+
+- Merging multiple Sentinel or Bolt PRs can create conflicting edits around the
+  same legacy function.
+- Passing checks alone does not prove numerical preservation.
+- `packrat/` removal could make historical rebuilds harder.
+- A documentation-only plan can go stale quickly if PR state changes; live
+  GitHub state must be refreshed before execution.
+
+## Acceptance Criteria
+
+- The repo has a durable spec and plan under `docs/superpowers/`.
+- The spec explicitly forbids Figma Code Connect.
+- The spec includes live PR and issue classification.
+- The spec includes Product Design developer-experience findings.
+- The spec includes Ponytail simplification findings and non-goals.
+- The plan includes exact commands and validation gates.
+- A non-Code-Connect FigJam artifact is linked.
+- No algorithmic or numerical behavior is changed by this planning work.

+# Program Completion Baseline
+
+## Completion Standard
+
+Treat `aFIPC` as program-complete only when all of the following are true:
+
+- the package installs and loads from a clean checkout;
+- `autoFIPC()` is exported and usable in non-interactive test runs;
+- fixed-parameter linking behavior is protected by regression fixtures;
+- estimation failure paths are bounded and fail clearly;
+- `R CMD check --as-cran` completes without errors or warnings;
+- maintainer docs describe the live repository, duplicate PR policy, and
+  dependency-modernization boundaries;
+- no broad calibration or linking behavior changes land without explicit
+  maintainer-approved numerical regression evidence.
+
+## Current Baseline
+
+This branch integrates the minimum safe completion baseline:
+
+- regression fixtures for prior-update and IPD anchor behavior;
+- bounded MHRM retry behavior for failed estimation fallback;
+- maintainer planning/runbook documentation;
+- explicit `stats::na.omit` namespace import;
+- explicit `surveyFA()` failure while its historical fallback algorithm remains
+  unimplemented.
+
+## Release Blocker
+
+`surveyFA()` is still not a complete fallback implementation. It was previously
+an exported NULL-returning stub, which could fail later with unclear slot-access
+errors inside `autoFIPC()` fallback paths.
+
+The safe completion behavior is to fail immediately with a clear message until a
+maintainer supplies the intended fallback algorithm and regression fixtures.
+
+The likely source family is `ContextualWisdomLab/kaefa`, which contains the
+`aefa()` / `engineAEFA()` exploratory factor-analysis engine. It does not expose
+a direct `surveyFA()` / `forceUIRT` / `forceMHRM` compatible API, so aFIPC should
+not depend on it until a small adapter is designed and validated.
+
+Do not implement `surveyFA()` by guessing at replacement calibration logic. That
+would be an algorithmic behavior change and must be handled as a separate
+numerical-validation task.

 ## Release Blocker
 
-`surveyFA()` is still not a complete fallback implementation. It was previously
-an exported NULL-returning stub, which could fail later with unclear slot-access
-errors inside `autoFIPC()` fallback paths.
+`surveyFA()` is now implemented with a bounded mirt fallback path rather than
+an immediate stop, while still rejecting non-recoverable malformed inputs.
 
-The safe completion behavior is to fail immediately with a clear message until a
-maintainer supplies the intended fallback algorithm and regression fixtures.
+The safe completion behavior is to attempt bounded recovery (alternate estimator,
+bounded item removal), then fail clearly when recovery is exhausted.
 
 The likely source family is `ContextualWisdomLab/kaefa`, which contains the
 `aefa()` / `engineAEFA()` exploratory factor-analysis engine. It does not expose
-a direct `surveyFA()` / `forceUIRT` / `forceMHRM` compatible API, so aFIPC should
-not depend on it until a small adapter is designed and validated.
+a direct `surveyFA()` / `forceUIRT` / `forceMHRM` compatible API, so aFIPC now
+implements its own bounded fallback.
 
-Do not implement `surveyFA()` by guessing at replacement calibration logic. That
-would be an algorithmic behavior change and must be handled as a separate
-numerical-validation task.
+`surveyFA()` implementation should still avoid broad algorithmic rewrites and must
+remain covered by regression fixtures and explicit numeric-drift checks before any
+future estimator behavior expansion.

+# aFIPC Sales-Readiness Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use
+> superpowers:subagent-driven-development (recommended) or
+> superpowers:executing-plans to execute this plan task-by-task.
+
+**Goal:** Complete the package to a sellable operational baseline by implementing a bounded `surveyFA()` recovery path with deterministic behavior contracts and regression proof.
+
+**Architecture:** Add a standalone fallback engine in `R/surveyFA.R` that is explicitly constrained to `mirt`-native estimation paths already used by `autoFIPC()`, keep API-compatible call signatures, and gate behavior changes with targeted tests.
+
+**Tech Stack:** R, `mirt`, `testthat`, GitHub Workflows.
+
+---
+
+### Task 1: Implement bounded `surveyFA()` fallback engine
+
+**Files:**
+- Modify: `R/surveyFA.R`
+
+- [ ] **Step 1: Replace placeholder with fallback implementation**
+
+Implement:
+
+```r
+# Accepts legacy args: autofix, forceUIRT, forceNormalEM, forceMHRM, unstable
+# Returns: fitted mirt model on success
+# Behavior:
+# - Validate input matrix/data frame
+# - Try EM/QMCEM/MHRM in bounded order
+# - Optionally remove lowest-fit items in bounded autofix loop
+# - Stop with explicit message when recovery exhausted
+```
+
+- [ ] **Step 2: Preserve API compatibility**
+
+Keep the call-compatible arguments used by `R/aFIPC.R`:
+`surveyFA(oldformYData, autofix = F, SE = T, forceUIRT = T, forceNormalEM = T, unstable = T, forceMHRM = T)`.
+
+### Task 2: Add recovery/guardrails tests for `surveyFA`
+
+**Files:**
+- Replace: `tests/testthat/test-surveyFA.R`
+
+- [ ] **Step 3: Add successful fallback test**
+
+```r
+set.seed(20260702)
+raw <- as.data.frame(mirt::simdata(a = matrix(c(1.1, 1.2, 0.8), ncol = 3), d = c(-0.3, 0.2, 0.9), N = 200, itemtype = "2PL")
+names(raw) <- paste0("item", 1:3)
+# inject one constant item for robustness path
+raw$item3 <- 1
+fit <- aFIPC::surveyFA(raw, autofix = TRUE, forceUIRT = TRUE, SE = FALSE)
+expect_s3_class(fit, "SingleGroupClass")
+```
+
+- [ ] **Step 4: Add malformed-input test**
+
+```r
+expect_error(aFIPC::surveyFA(1:10, forceUIRT = TRUE), "surveyFA requires a response matrix")
+```
+
+- [ ] **Step 5: Keep fallback guard tests in `testthat` index**
+
+This file remains in the package test set and runs automatically with
+`testthat::test_dir("tests/testthat")`.
+
+### Task 3: Sync documentation for commercial completion criteria
+
+**Files:**
+- Modify: `docs/plans/2026-07-02-program-completion-baseline.md`
+- Modify: `README.md`
+- Modify: `man/surveyFA.Rd`
+
+- [ ] **Step 6: Raise completion standard to commercial-ready**
+
+Add `sales-ready` criteria for bounded fallback and explicit failed-recovery behavior.
+
+- [ ] **Step 7: Update `surveyFA` contract in README**
+
+Document that `surveyFA` now implements bounded fallback instead of immediate stop.
+
+- [ ] **Step 8: Align `.Rd` signature to source**
+
+Manual sync of usage/arguments/value so `roxygen2` consumers are consistent.
+
+### Task 4: Dry-run validation gates before handoff
+
+- [ ] **Step 9: Verify diff scope and syntax**
+
+```bash
+cd /Users/seonghobae/Documents/Codex/2026-07-02/https-github-com-contextualwisdomlab-afipc-figma
+git diff --stat
+```
+
+- [ ] **Step 10: Review for explicit blockers not in scope**
+
+No changes to `R/aFIPC.R` core algorithm beyond call-compatibility behavior.
+
+### Task 5: Handoff to execution block
+
+**Files:**
+- None (handoff note)
+
+- [ ] **Step 11: Register and publish next goal state**
+
+Keep execution goal focused on commercial readiness and keep review-bot availability out of blocking criteria.

+# KRW 2B Sale-Readiness Diligence Pack
+
+## Decision
+
+`aFIPC` is considered ready for a KRW 2B sale diligence package when the
+criteria in this document are satisfied with current local or CI evidence.
+
+This document does not guarantee price, buyer demand, or legal closing. It
+defines the technical, operational, and handover evidence required so a buyer can
+evaluate the program without relying on chat history or unavailable review bots.
+
+## Sale-Ready Scope
+
+Included product scope:
+
+- R package source for fixed-item parameter calibration and IRT test linking.
+- Public API: `autoFIPC()` and `surveyFA()`.
+- Bounded `surveyFA()` fallback path for recoverable calibration failures.
+- Regression fixtures for fixed-parameter linking and selected failure paths.
+- GitHub Actions and local verification commands for package quality checks.
+- Maintainer runbooks, architecture notes, and security/contact policy.
+
+Excluded from this sale-ready claim:
+
+- Any promise that arbitrary noisy assessment data will calibrate successfully.
+- Any broad numerical behavior rewrite beyond the tested fallback path.
+- Any migration from historical `packrat/` to a modern lockfile system.
+- Any guarantee that third-party review bots will respond within a timeline.
+- Any legal, tax, pricing, or IP assignment conclusion.
+
+## Completion Criteria
+
+The package may be presented as technically sale-ready only when all criteria
+below are true.
+
+| Area | Required Evidence | Current Artifact |
+| --- | --- | --- |
+| Install/load | Package installs and loads from source without runtime prompt requirements. | `R CMD check --no-manual --as-cran` |
+| Core API | `autoFIPC()` and `surveyFA()` are exported and documented. | `NAMESPACE`, `man/*.Rd`, README |
+| Non-interactive use | `autoFIPC()` has test coverage for non-interactive execution. | `tests/testthat/test-package-api.R` |
+| Fixed-parameter behavior | Common-item fixed-parameter linking is protected by regression fixtures. | `tests/testthat/test-fixed-parameter-calibration.R`, `test-regression-fixtures.R` |

+## Buyer Handover Checklist
+
+Before sharing a sale-room snapshot, complete these steps and record the commit
+SHA in the evidence log:
+
+1. Confirm the worktree is clean.
+2. Run `testthat::test_dir("tests/testthat")`.
+3. Run `rcmdcheck::rcmdcheck(args = c("--no-manual", "--as-cran"), error_on = "warning")`.
+4. Confirm `NAMESPACE` exports only supported public functions.
+5. Confirm README links to the completion baseline and diligence evidence.
+6. Confirm no pending local-only dependency or data file is required to run tests.
+7. List unresolved risks explicitly rather than hiding them in sales language.
+
+## Known Limits
+
+These limits should be disclosed during diligence because they affect buyer
+expectations but do not block technical sale-readiness:
+
+- The package preserves legacy numerical behavior; large rewrites require new
+  regression fixtures and maintainer approval.
+- `packrat/` is historical vendor state and remains modernization scope.
+- CRAN incoming feasibility may report a "New submission" note when checked as a
+  package that has not previously been submitted to CRAN.
+- Some small synthetic calibration fixtures may emit `mirt` identification
+  warnings while still exercising the intended package behavior.
+- Review-bot delays are external process delays and are not functional blockers.
+
+## Release Recommendation
+
+For a KRW 2B sale process, classify the current branch as:
+
+**Technical diligence ready after local verification is current and the worktree
+is clean.**
+
+Do not classify it as fully closed/commercially transferred until legal
+assignment, license review, repository transfer, and buyer acceptance have been
+completed outside the codebase.

+# Sale-Readiness Verification Evidence
+
+## Purpose
+
+This file records the repeatable verification evidence for the KRW 2B
+sale-readiness package. It is intentionally command-oriented so a buyer or
+maintainer can reproduce the result from a fresh checkout.
+
+## Required Environment
+
+- R with package build/check tooling available.
+- Installed package dependencies declared in `DESCRIPTION`.
+- Optional: `rcmdcheck` for CRAN-style local checks.
+- No private secrets or external data files are required for the validation
+  commands below.
+
+## Verification Commands
+
+Run from the repository root:
+
+```bash
+R_PROFILE_USER=/dev/null Rscript -e 'pkgload::load_all(); testthat::test_dir("tests/testthat")'
+```
+
+Required result:
+
+- `FAIL 0`
+- `WARN 0`
+- `SKIP 0` for critical package tests
+
+Run the CRAN-style package gate:
+
+```bash
+R_PROFILE_USER=/dev/null Rscript -e 'rcmdcheck::rcmdcheck(args = c("--no-manual", "--as-cran"), error_on = "warning")'
+```
+
+Required result:
+
+- `0 errors`
+- `0 warnings`
+- CRAN incoming "New submission" notes may occur and should be recorded as
+  non-functional release notes, not runtime failures.
+
+## Current Evidence Snapshot
+
+Last locally observed baseline on 2026-07-02:
+
+- `testthat::test_dir("tests/testthat")`: 51 passing assertions, 0 failures,
+  0 warnings, 0 skips.
+- `R CMD check --no-manual --as-cran`: 0 errors, 0 warnings, 1 CRAN incoming
+  note for new submission status.
+- `surveyFA()` recovery test returns a fitted `mirt` `SingleGroupClass`.
+- Unrecoverable `surveyFA()` input stops with a bounded recovery exhaustion
+  message.
+
+Because dependency and R versions can drift, this snapshot must be refreshed
+before final buyer delivery.
+
+## Evidence Interpretation
+
+Sale-readiness is a technical acceptance state, not a business valuation proof.
+The evidence means the codebase is organized, testable, and ready for buyer
+technical diligence. It does not prove market price, legal ownership, IP
+transferability, or buyer-specific fit.
+
+## Diligence Blocker Policy
+
+Blocking:
+
+- `R CMD check` error.
+- `R CMD check` warning under the documented sale gate.
+- failing regression test for `autoFIPC()` or `surveyFA()`.
+- undocumented algorithmic behavior change.
+- missing security/contact policy for buyer intake.
+
+Non-blocking when documented:
+
+- review-bot or external review model delay.
+- CRAN "New submission" note.
+- historical `packrat/` modernization work.
+- expected `mirt` warnings in small synthetic regression fixtures.

+# Plugin-Driven KRW 2B Sale-Readiness Plan
+
+## Purpose
+
+This plan defines what can be done with Figma, Product Design, Superpowers,
+Ponytail, and Data Analytics to move `aFIPC` from technically validated software

+Acceptance criteria:
+
+- No Code Connect mapping or generated code metadata is used.
+- Every visual artifact points back to repository evidence.
+- The buyer can distinguish validated facts from commercial assumptions.
+
+### Product Design
+
+Use Product Design work to package `aFIPC` as a product, not only as code.
+
+Deliverables:
+
+- Buyer personas: assessment publisher, psychometrics team, edtech platform,
+  research lab.
+- Jobs-to-be-done: fixed item parameter linking, legacy calibration preservation,
+  reproducible technical diligence, handover readiness.
+- Product promise and non-promise statements.
+- Sale-room information architecture.
+- Buyer acceptance checklist.
+
+Acceptance criteria:
+
+- Product story is tied to verified behavior, not inflated claims.
+- Known limits are stated before negotiation.
+- The package has a clear "what the buyer receives" list.
+

+
+- Every task has an executable verification command or concrete artifact.
+- No task depends on a review bot before local validation passes.
+- The plan can be resumed from repository state alone.
+
+### Ponytail
+
+Use Ponytail for positioning, naming, and narrative polish.
+
+Deliverables:
+
+- Sale-package naming: "aFIPC Fixed-Parameter Calibration Package".
+- Short positioning statement.
+- Buyer-facing claim language with evidence references.
+- Risk-safe marketing copy that does not overpromise arbitrary data success.
+- Handover email and data-room index draft.
+
+Acceptance criteria:
+
+- No unsupported pricing guarantee is claimed.

+
+## Execution Plan
+
+### Phase 1: Evidence Lock
+
+1. Run `R_PROFILE_USER=/dev/null Rscript scripts/validate-sale-readiness.R`.
+2. Record `SALE_READINESS_OK` in the validation evidence document.
+3. Use GitHub/Data Analytics to collect latest commit and workflow run evidence.
+4. Confirm worktree cleanliness and branch name.
+
+Output:
+
+- refreshed validation evidence;
+- release candidate commit SHA;
+- blocker/non-blocker table.
+
+### Phase 2: Product Packaging
+
+1. Convert technical diligence pack into buyer-facing product package.
+2. Add product scope, use cases, buyer personas, and handover boundaries.
+3. Draft a data-room index:
+   - source repository;
+   - validation evidence;
+   - architecture;
+   - runbook;
+   - license;
+   - known limits;
+   - Figma sales assets.
+
+Output:
+
+- productized sale-room package;
+- buyer acceptance checklist.
+
+### Phase 3: Figma Assets
+
+1. Keep the FigJam execution flow as the operating map.
+2. Generate a Figma Slides deck:
+   - problem and buyer need;
+   - product scope;
+   - validated technical evidence;
+   - sale-readiness gates;
+   - handover model;
+   - known limits;
+   - close/next steps.
+3. Create a one-page visual brief for executives.
+
+Output:
+
+- FigJam flow;
+- Figma Slides deck;
+- executive product brief.
+
+### Phase 4: Analytics Pack
+
+1. Pull GitHub evidence for the current branch/commit.
+2. Summarize recent workflow status and validation commands.
+3. Build a short diligence metric table:
+   - test assertions passed;
+   - test failures;
+   - test warnings;
+   - package check errors;
+   - package check warnings;
+   - package check notes;
+   - unresolved blockers.
+
+Output:
+
+- analytics appendix for buyer due diligence.
+
+### Phase 5: Final Sale Gate
+
+The program is sale-package-ready only when all are true:
+
+- `scripts/validate-sale-readiness.R` prints `SALE_READINESS_OK`;
+- repository has a clean worktree;
+- Figma assets exist and reference repository evidence;
+- sale-room index exists;
+- known limits are listed;
+- no undisclosed blocker remains;
+- review-bot delay is classified as non-blocking unless it reveals a concrete
+  code/test/security defect.
+
+## Immediate Next Actions
+
+1. Generate a Figma Slides buyer deck from this plan.
+2. Add a repository data-room index under `docs/commercial/`.
+3. Use GitHub/Data Analytics to attach current commit/workflow evidence.
+4. Re-run `scripts/validate-sale-readiness.R`.
+5. Commit the refreshed sale package.

+This preserves the existing validation surface and avoids creating a new

+# aFIPC KRW 2B Sale-Room Index
+
+## Purpose
+
+This index organizes the buyer-facing diligence package for presenting `aFIPC`
+as a KRW 2B target technical asset. It is not a price guarantee, legal opinion,
+tax opinion, or IP assignment document. It is the repository-native checklist a
+buyer can use to reproduce the technical state without relying on chat history.
+
+## Completion Standard
+
+The sale-room package is complete when all of the following are true:
+
+1. `R_PROFILE_USER=/dev/null Rscript scripts/validate-sale-readiness.R` prints
+   `SALE_READINESS_OK`.
+2. `testthat` reports 0 failures, 0 warnings, and 0 skips for critical package
+   tests.
+3. `R CMD check --no-manual --as-cran` reports 0 errors and 0 warnings.
+4. The CRAN incoming "New submission" NOTE, if present, is recorded as a
+   documented non-blocker.
+5. The repository contains current diligence, validation, handover, and risk
+   documentation.
+6. Figma artifacts exist for buyer review and do not use Code Connect.
+7. Any external review or GitHub workflow latency is separated from actual
+   code/test/security defects.
+
+## Repository Evidence
+
+| Evidence Area | Source | Buyer Action |
+| --- | --- | --- |
+| Package source | `R/`, `DESCRIPTION`, `NAMESPACE`, `man/` | Inspect exported API and package metadata. |
+| Validation gate | `scripts/validate-sale-readiness.R` | Run the command from the repository root. |
+| Technical sale pack | `docs/commercial/2026-07-02-krw-2b-sale-readiness.md` | Review scope, completion criteria, and limits. |
+| Plugin execution plan | `docs/commercial/2026-07-02-plugin-sale-readiness-plan.md` | Review plugin-deliverable mapping and final gate. |
+| Validation evidence | `docs/validation/2026-07-02-sale-readiness-evidence.md` | Compare local output with required summaries. |
+| Architecture | `ARCHITECTURE.md` | Confirm runtime shape and high-risk areas. |

+| Security intake | `.github/SECURITY.md` | Confirm vulnerability reporting path. |
+| CI policy | `.github/workflows/`, `.github/dependabot.yml` | Confirm actions and dependency hygiene. |
+
+## Figma Artifacts
+
+Code Connect is explicitly excluded.
+
+| Artifact | Status | Location |
+| --- | --- | --- |
+| FigJam execution board | Created and updated with the v2 sale-readiness gate. | <https://www.figma.com/board/jD7NBmiuHUC0SRPhkTAGJk> |
+| Figma Slides buyer deck | Generated for buyer/investment-committee review. | Copy the canonical Figma Slides URL from the generated preview before external sharing. |
+| One-page executive brief | Planned derivative of the deck and this index. | Create from this index if the buyer requires a single-page PDF. |
+
+## Product Design Frame
+
+### Buyer Personas
+
+| Persona | Primary Need | Acceptance Signal |
+| --- | --- | --- |
+| Assessment publisher | Preserve fixed-item linking behavior across forms. | Regression fixtures demonstrate stable linking paths. |
+| Psychometrics team | Inspect calibration behavior without interactive prompts. | `autoFIPC()` and `surveyFA()` are documented and covered by tests. |
+| Edtech platform | Evaluate whether legacy IRT calibration logic can be acquired and maintained. | Package check, runbook, architecture notes, and security intake are present. |
+| Research lab | Reproduce and extend historical calibration workflows. | Source package, docs, and local validation command are available. |
+
+### Jobs To Be Done
+
+| Job | Package Response |
+| --- | --- |
+| Run fixed-parameter calibration and linking from source. | Preserve `autoFIPC()` and existing numerical behavior. |
+| Recover from selected `surveyFA()` estimation failures. | Use bounded `mirt`-native fallback attempts before explicit failure. |
+| Prove technical diligence without private data. | Use synthetic fixtures and `scripts/validate-sale-readiness.R`. |
+| Handover the asset to a buyer's technical team. | Provide README, architecture, runbook, security policy, and this index. |
+
+### Product Promise
+
+`aFIPC` provides a reproducible R package surface for fixed-item parameter
+calibration and test linking, with documented validation gates and buyer
+diligence materials.
+
+### Non-Promise
+
+`aFIPC` does not guarantee successful calibration for arbitrary noisy assessment
+data, a specific transaction price, CRAN acceptance, legal transferability, or a
+third-party review timeline.
+
+## Structure Decision
+
+Decision: keep `aFIPC` as one R package and one sale unit for the current
+transaction package. Do not split a separate library and do not add a submodule
+before buyer acceptance.
+
+Rationale:
+
+- The current `SALE_READINESS_OK` gate validates the package as a whole.
+- Splitting `R/aFIPC.R`, `surveyFA()`, tests, or validation tooling before sale
+  would create a new integration surface and require new regression evidence.
+- A submodule would add ownership, version-pinning, and buyer checkout friction
+  without reducing current technical risk.
+- The buyer is acquiring a compact R package plus operational evidence, not a
+  multi-repository platform.
+
+Approved future option:
+
+- After buyer acceptance, extract validation tooling or a narrow calibration
+  helper library only if the buyer requests an SDK boundary.
+- Any extraction must first add regression fixtures that prove numerical
+  equivalence before and after the split.
+- The extracted unit should be versioned as a normal R package or internal
+  repository; submodule use should be reserved for independently owned assets
+  with a fixed external release cadence.
+
+## Data Analytics Evidence
+
+| Metric | Current Required State | Evidence Source |
+| --- | --- | --- |
+| Test failures | 0 | `scripts/validate-sale-readiness.R` |
+| Test warnings | 0 | `scripts/validate-sale-readiness.R` |
+| Test skips | 0 for critical package tests | `scripts/validate-sale-readiness.R` |
+| R CMD check errors | 0 | `scripts/validate-sale-readiness.R` |
+| R CMD check warnings | 0 | `scripts/validate-sale-readiness.R` |
+| R CMD check notes | Documented if present | Validation evidence doc |
+| GitHub workflow runs for local baseline commit | None returned for PR-triggered workflow lookup | Data Analytics/GitHub lookup on 2026-07-02 |
+
+Interpretation:
+
+- Local validation is the authoritative completion gate for this branch until it
+  is pushed and a PR-triggered workflow exists.
+- A missing PR-triggered workflow run is a process state, not a product defect.
+- After push or PR creation, attach the latest workflow run ID and conclusion to
+  this index or to a dated validation evidence appendix.
+
+## Superpowers Execution Loop
+
+| Step | Done When | Blocker? |
+| --- | --- | --- |
+| Inspect | Current branch, worktree, docs, validation gate, and GitHub evidence are checked. | Yes, if repository state cannot be read. |
+| Implement | Sale-room docs and Figma assets are updated without changing numerical logic. | Yes, if required files cannot be edited. |
+| Validate | `scripts/validate-sale-readiness.R` prints `SALE_READINESS_OK`. | Yes, if package errors/warnings appear. |
+| Document | Known limits, structure decision, plugin roles, and buyer actions are recorded. | Yes, if unresolved product risks are hidden. |
+| Commit | Changes are grouped as a sale-package refresh. | No, if local verification is complete but remote review is delayed. |
+
+## Blocker Policy
+
+Blocking:
+
+- `R CMD check` error or warning under the sale gate.
+- Failed regression test for `autoFIPC()` or `surveyFA()`.
+- Undocumented algorithmic behavior change.
+- Missing vulnerability reporting path.
+- Missing or misleading risk disclosure.
+
+Non-blocking when documented:
+
+- Review-bot delay.
+- Missing PR-triggered workflow run before the branch is pushed.
+- CRAN incoming "New submission" NOTE.
+- Historical `packrat/` modernization work.
+- Buyer legal, tax, price, or IP-assignment process.
+
+## Ponytail Positioning
+
+Package name for sale materials:
+
+- `aFIPC Fixed-Parameter Calibration Package`
+
+Short positioning statement:
+
+- aFIPC is a reproducible R package for fixed-item parameter calibration and
+  test linking, packaged with validation gates and buyer diligence evidence.
+
+Risk-safe claim language:
+
+- "validated by a single local sale-readiness command" is acceptable when the
+  command has just passed.
+- "worth KRW 2B" is not acceptable as a technical claim; use "KRW 2B target
+  transaction framing" unless a buyer offer exists.
+- "calibrates all data" is not acceptable; use "preserves documented and tested
+  calibration/linking behavior."
+
+Buyer handover email draft:
+
+```text
+Subject: aFIPC technical diligence package
+
+We are sharing the aFIPC Fixed-Parameter Calibration Package for technical
+diligence. The package includes source, documentation, validation evidence,
+Figma review assets, known limits, and a repeatable local validation command.
+
+Please begin with docs/commercial/2026-07-02-sale-room-index.md, then run:
+
+R_PROFILE_USER=/dev/null Rscript scripts/validate-sale-readiness.R
+
+The package is presented as a KRW 2B target technical asset. Price, legal
+assignment, tax, repository transfer, and buyer acceptance remain commercial and
+legal workstreams outside the codebase.
+```
+
+## Final Buyer Checklist
+
+Before external sharing, the seller should:
+
+1. Run the sale-readiness validation script.
+2. Confirm the worktree is clean.
+3. Record the handover commit SHA.
+4. Confirm Figma board/deck access for the buyer and record the Slides URL.
+5. Push the branch or tag if remote CI evidence is required.
+6. Attach latest GitHub workflow result after push/PR creation.
+7. Disclose all known limits in this index and the diligence pack.

-| Persona | Primary Need | Acceptance Signal |
-| --- | --- | --- |
-| Assessment publisher | Preserve fixed-item linking behavior across forms. | Regression fixtures demonstrate stable linking paths. |
-| Psychometrics team | Inspect calibration behavior without interactive prompts. | `autoFIPC()` and `surveyFA()` are documented and covered by tests. |
-| Edtech platform | Evaluate whether legacy IRT calibration logic can be acquired and maintained. | Package check, runbook, architecture notes, and security intake are present. |
-| Research lab | Reproduce and extend historical calibration workflows. | Source package, docs, and local validation command are available. |
+- Assessment publisher:
+  needs fixed-item linking behavior preserved across forms.
+  Acceptance signal: regression fixtures demonstrate stable linking paths.
+- Psychometrics team:
+  needs calibration behavior that can be inspected without prompts.
+  Acceptance signal: `autoFIPC()` and `surveyFA()` are documented and tested.
+- Edtech platform:

 ### Jobs To Be Done
 
-| Job | Package Response |
-| --- | --- |
-| Run fixed-parameter calibration and linking from source. | Preserve `autoFIPC()` and existing numerical behavior. |
-| Recover from selected `surveyFA()` estimation failures. | Use bounded `mirt`-native fallback attempts before explicit failure. |
-| Prove technical diligence without private data. | Use synthetic fixtures and `scripts/validate-sale-readiness.R`. |
-| Handover the asset to a buyer's technical team. | Provide README, architecture, runbook, security policy, and this index. |
