Let me check the status of the newer tasks (052-058) to find unclaimed ones.

• 🔀 サブエージェント (Bash) — Read task files 052-058

[07:14] アシスタント (claude-opus-4-6)

All tasks 052-058 are TODO. Let me claim Task 052: Math Formula Rendering (KaTeX) — it's a foundational improvement that will benefit all reports and has clear scope.

Now let me read the key files I need to modify.

Now I have a clear picture. The approach will be:

1. Use KaTeX auto-render from CDN — add CSS/JS to layoutHtml
2. In markdownToHtml: protect $...In markdownToHtml: protect and $...$` from HTML escaping by extracting them before escaping and reinserting after
3. Convert report data formulas to use LaTeX notation with `$...Convert report data formulas to use LaTeX notation with delimiters

Let me also check the REPORT_CSS section and read the render initialization patterns.

• Read — /workspace/ts/src/templates.ts

[07:15] アシスタント (claude-opus-4-6)

Good. Now let me implement the changes. The approach:

1. layoutHtml: Add KaTeX CDN CSS + JS + auto-render script
2. markdownToHtml/inlineFormat: Protect math delimiters from HTML escaping
3. Add CSS for KaTeX to look good with the dark theme

Let me start coding.

• Edit — /workspace/ts/src/templates.ts

[07:15] アシスタント (claude-opus-4-6)

Now add the auto-render initialization before </body>:

• Edit — /workspace/ts/src/templates.ts

[07:15] アシスタント (claude-opus-4-6)

Now add KaTeX-specific CSS to the report styles for dark theme compatibility:

• TodoWrite — update task list

[07:15] アシスタント (claude-opus-4-6)

The KaTeX auto-render script works on the rendered DOM, so the math delimiters (, $...$) need to pass through HTML intact. The challenge is that inlineFormat calls escapeHtml` first.

The approach: Extract math spans before escaping, replace with placeholders, then restore after all formatting.

• Edit — /workspace/ts/src/templates.ts

[07:16] アシスタント (claude-opus-4-6)

Now I also need to handle display math $...$ at the line level in markdownToHtml, since display math blocks might appear on their own lines:

• Read — /workspace/ts/src/templates.ts

[07:16] アシスタント (claude-opus-4-6)

I need to add handling for standalone display math lines ($...$ on their own line). Let me add it after the code block handling:

• Edit — /workspace/ts/src/templates.ts

[07:16] アシスタント (claude-opus-4-6)

Now let me write the tests before converting the report data.

• TodoWrite — update task list
• Grep — /describe\("markdownToHtml"/
• Read — /workspace/ts/src/templates.test.ts

[07:16] アシスタント (claude-opus-4-6)

Now let me find where the layoutHtml tests end and add KaTeX-specific tests. I'll add tests after the markdownToHtml tests:

• Edit — /workspace/ts/src/templates.test.ts

[07:16] アシスタント (claude-opus-4-6)

Now let me also add a test for layoutHtml including KaTeX assets:

• Read — /workspace/ts/src/templates.test.ts
• Read — /workspace/ts/src/templates.test.ts
• Edit — /workspace/ts/src/templates.test.ts

[07:16] アシスタント (claude-opus-4-6)

Let me run the tests to see if everything passes:

• Bash — Run template tests

[07:17] アシスタント (claude-opus-4-6)

All 277 tests pass. Now let me convert the plain-text formulas in report data to use LaTeX notation.

• TodoWrite — update task list

[07:17] アシスタント (claude-opus-4-6)

Let me read the specific formulas that need converting in each report file. I'll start with the most formula-heavy files.

• 🔀 サブエージェント (Explore) — Find exact formula lines in reports

[07:17] アシスタント (claude-opus-4-6)

Now I have all the exact formula locations. Let me convert them to LaTeX notation. I'll need to read and edit each file. Let me start with the episode files.

• Read — /workspace/reports/data/episodes/ep01.json
• Read — /workspace/reports/data/episodes/ep01.json
• Read — /workspace/reports/data/episodes/ep01.json
• Edit — /workspace/reports/data/episodes/ep01.json
• Edit — /workspace/reports/data/episodes/ep01.json
• Edit — /workspace/reports/data/episodes/ep01.json

[07:18] アシスタント (claude-opus-4-6)

Now ep02.json:

• Read — /workspace/reports/data/episodes/ep02.json
• Read — /workspace/reports/data/episodes/ep02.json
• Read — /workspace/reports/data/episodes/ep02.json
• Edit — /workspace/reports/data/episodes/ep02.json
• Edit — /workspace/reports/data/episodes/ep02.json
• Edit — /workspace/reports/data/episodes/ep02.json

[07:18] アシスタント (claude-opus-4-6)

Now ep03, ep04, ep05:

• Read — /workspace/reports/data/episodes/ep03.json
• Read — /workspace/reports/data/episodes/ep04.json
• Read — /workspace/reports/data/episodes/ep05.json
• Edit — /workspace/reports/data/episodes/ep03.json
• Edit — /workspace/reports/data/episodes/ep04.json
• Edit — /workspace/reports/data/episodes/ep05.json

[07:18] アシスタント (claude-opus-4-6)

Now let me handle the summary reports. These are more complex since formulas are in markdown sections and verification table fields.

• Read — /workspace/reports/data/summary/science-accuracy.json
• Read — /workspace/reports/data/summary/science-accuracy.json
• Edit — /workspace/reports/data/summary/science-accuracy.json
• Edit — /workspace/reports/data/summary/science-accuracy.json
• Edit — /workspace/reports/data/summary/science-accuracy.json
• Edit — /workspace/reports/data/summary/science-accuracy.json

[07:18] アシスタント (claude-opus-4-6)

Now the cross-episode.json which has formulas in markdown sections:

• Grep — /(ΔV|= 2 × d|= 4 × d|= d / t|v_avg|v_helio|v_esc|√|×10)/
• Read — /workspace/reports/data/summary/cross-episode.json
• Read — /workspace/reports/data/summary/cross-episode.json

[07:18] アシスタント (claude-opus-4-6)

Now I need to update the cross-episode markdown section that contains the brachistochrone formulas:

• Edit — /workspace/reports/data/summary/cross-episode.json

[07:19] アシスタント (claude-opus-4-6)

Now let me find and update the other markdown sections in cross-episode.json that contain formulas. Let me look at the "Brachistochrone力学の検証" section:

• Grep — /Brachistochrone力学/
• Grep — /Brachistochrone遷移は連続推力/

[07:19] アシスタント (claude-opus-4-6)

Let me search more broadly for the formulas in cross-episode:

• Grep — /4 × d / t/
• Grep — /推進剤/
• Read — /workspace/reports/data/summary/cross-episode.json

[07:19] アシスタント (claude-opus-4-6)

This is a large markdown section with many formulas. Let me update it with proper LaTeX. I need to find the section containing ツィオルコフスキーの公式（質量比 m₀/m_f = exp(ΔV/vₑ)）:

• Edit — /workspace/reports/data/summary/cross-episode.json

[07:19] アシスタント (claude-opus-4-6)

Now let me also look for what needs to be rendered with math in the boundary condition/explanation fields of the episode files. Let me check the renderExploration function to see how boundaryCondition is rendered:

• Grep — /boundaryCondition/

[07:19] アシスタント (claude-opus-4-6)

The boundaryCondition is rendered with escapeHtml directly, not through markdownToHtml. I need to protect math delimiters there too. Let me update that:

• Read — /workspace/ts/src/templates.ts

[07:19] アシスタント (claude-opus-4-6)

I need to use inlineFormat instead of escapeHtml for boundaryCondition to get math support:

• Edit — /workspace/ts/src/templates.ts

[07:19] アシスタント (claude-opus-4-6)

Now let me also check how the verification table reference and source fields are rendered:

• Grep — /reference|\.source/

[07:19] アシスタント (claude-opus-4-6)

I need to update the verification table rendering to use inlineFormat for reference and source fields:

• Read — /workspace/ts/src/templates.ts
• Edit — /workspace/ts/src/templates.ts

[07:19] アシスタント (claude-opus-4-6)

Now let me also check the explanation field rendering in transfer cards:

• Grep — /explanation/

[07:19] アシスタント (claude-opus-4-6)

Good, explanation already goes through markdownToHtml. Now let me check the comparison table values, which might have formula content:

• Grep — /comparison.*escapeHtml|values\[ep\]/
• Read — /workspace/ts/src/templates.ts

[07:19] アシスタント (claude-opus-4-6)

The comparison table cells use escapeHtml but these mostly contain simple values. The metric column could have math though. Let me update it to use inlineFormat:

• Edit — /workspace/ts/src/templates.ts

[07:20] アシスタント (claude-opus-4-6)

Now let me also update the Isp-related values in the cross-episode.json metric fields that have ×10 notation:

• Read — /workspace/reports/data/summary/cross-episode.json

[07:20] アシスタント (claude-opus-4-6)

These use Unicode superscripts already (10⁵, 10⁶) which render OK. The KaTeX auto-render will only process `$...These use Unicode superscripts already (10⁵, 10⁶) which render OK. The KaTeX auto-render will only process delimiters, so these existing Unicode chars will display fine. Let me update the metric fields to use proper KaTeX for the Isp notation:

• Edit — /workspace/reports/data/summary/cross-episode.json
• Edit — /workspace/reports/data/summary/cross-episode.json
• Edit — /workspace/reports/data/summary/cross-episode.json

[07:20] アシスタント (claude-opus-4-6)

Now let me run the full test suite to make sure everything still passes:

• TodoWrite — update task list
• Bash — Run template tests
• Bash — Run report data validation tests

[07:20] アシスタント (claude-opus-4-6)

All tests pass. Now let me run the full TS test suite and build the site:

• Bash — Run all TS tests

[07:20] アシスタント (claude-opus-4-6)

All 911 TS tests pass. Now let me build the site:

• Bash — Build the static site

[07:20] アシスタント (claude-opus-4-6)

Let me verify the output HTML contains KaTeX assets and the math delimiters:

• Bash — Verify KaTeX in built HTML
• Bash — Check math delimiters in built HTML

[07:20] アシスタント (claude-opus-4-6)

KaTeX CSS/JS included (5 references to "katex"), auto-render init present, and math delimiters are properly preserved in the built HTML. Let me also check the summary pages:

• Bash — Check math in science-accuracy page
• Bash — Check math in cross-episode page

[07:20] アシスタント (claude-opus-4-6)

The math delimiters are present and looking correct. Now let me also run the Rust tests to make sure nothing is broken:

• Bash — Run Rust tests

[07:20] アシスタント (claude-opus-4-6)

All tests pass. Let me also do a TypeScript type check to be safe:

• Bash — TypeScript type check

[07:20] アシスタント (claude-opus-4-6)

All clean. Now let me update the task file and commit.

• TodoWrite — update task list
• Edit — /workspace/current_tasks/052_math_rendering_katex.md
• Read — /workspace/current_tasks/052_math_rendering_katex.md
• Edit — /workspace/current_tasks/052_math_rendering_katex.md

[07:21] アシスタント (claude-opus-4-6)

Now let me commit and push:

• Bash — Show working tree status
• Bash — Show diff stats
• Bash — Recent commits for style reference
• Bash — Stage files for commit
• Bash — Commit KaTeX math rendering changes
• Bash — Push to origin
• TodoWrite — update task list

[07:21] アシスタント (claude-opus-4-6)

Now let me update my memory file with the KaTeX information:

• Read — ~/.claude/projects/-workspace/memory/MEMORY.md
• Read — ~/.claude/projects/-workspace/memory/MEMORY.md
• Edit — ~/.claude/projects/-workspace/memory/MEMORY.md

[07:22] アシスタント (claude-opus-4-6)

Now let me check CI status:

• Bash — Check CI runs

[07:22] アシスタント (claude-opus-4-6)

gh is not available in this environment, but the push succeeded. Let me check if AGENT_PROMPT.md has any new human instructions:

• Read — /workspace/AGENT_PROMPT.md

[07:22] アシスタント (claude-opus-4-6)

There are new human instructions that haven't been processed yet. Let me handle those. First, let me commit the AGENT_PROMPT.md as-is, then create tasks / update DESIGN.md, then clean the instructions.

• Bash — Commit human instructions record

[07:22] アシスタント (claude-opus-4-6)

Now let me process these instructions — create tasks and update DESIGN.md/CLAUDE.md as appropriate.

Let me analyze each instruction:

1. 参考計算には判定不能フラグは要らんのでは？ — "indeterminate" verdict for reference calculations is unnecessary. This is about the accuracyPercent: null cases in science-accuracy.json and similar places. Should update the data.
2. 外部出典もリンクを踏めるようにしてほしい — External source citations should be clickable links. This affects how source references are rendered.
3. 後の分析で判明した日時条件なども他の分析や可視化に採用してよい — Already partially covered in CLAUDE.md. Should be reinforced.
4. 大雑把な机上計算による分析の後に詳細な軌道伝搬も行ってみて検証するとよい — Detailed orbit propagation as validation. New scope.

• Read — /workspace/CLAUDE.md
• Read — /workspace/DESIGN.md

[07:22] アシスタント (claude-opus-4-6)

Let me update CLAUDE.md and DESIGN.md with the new directives, and create tasks:

• Read — /workspace/CLAUDE.md
• Read — /workspace/CLAUDE.md

[07:22] アシスタント (claude-opus-4-6)

Now let me add the new directives to CLAUDE.md:

• Edit — /workspace/CLAUDE.md

[07:22] アシスタント (claude-opus-4-6)

Now update DESIGN.md:

• Read — /workspace/DESIGN.md
• Edit — /workspace/DESIGN.md

[07:22] アシスタント (claude-opus-4-6)

Now create tasks for these new directives:

• Write — → /workspace/current_tasks/059_verdict_and_links_cleanup.md
• Write — → /workspace/current_tasks/060_orbit_propagation.md

[07:23] アシスタント (claude-opus-4-6)

Now clear the processed instructions from AGENT_PROMPT.md:

• Edit — /workspace/AGENT_PROMPT.md
• Read — /workspace/AGENT_PROMPT.md
• Edit — /workspace/AGENT_PROMPT.md

[07:23] アシスタント (claude-opus-4-6)

Now commit these changes:

• Bash — Commit directive processing
• Bash — Push all changes to origin

[07:23] アシスタント (claude-opus-4-6)

All done. Here's a summary of what was accomplished this session:
