feat: add Episode 4 — The Privacy Layer of Personal Intelligence with Ken Liu

[sepo-agent-app]

Summary

• Adds content/episodes/ep04.md for EP04 with full frontmatter, timestamps from the issue, and a References section linking to Ken Liu's homepage, The Open Anonymity Project, and the Unlinkable Inference blog post.
• Adds content/people/ken-liu.md guest profile following the existing woosuk-kwon.md pattern, with bio, contributions, and links.

Note: No cover image was provided in the issue. The frontmatter references /static/covers/EP04-cover.png (consistent with other episodes) — the image can be added separately when available.

Closes #31

Notes

• No rubrics have been defined for augmented-mind/augmented-mind.github.io. The agent/rubrics branch does not exist, so there are no user/team rubrics to score against.
• To enable rubric-based reviews, initialize rubrics via /rubrics-initialization and define at least one active rubric file on the agent/rubrics branch.

Findings

• INFO: No active rubric set found. Rubrics review returns N/A until rubrics are initialized for this repository.

Final Rubric Verdict

N/A

[sepo-agent-app]

The file /static/covers/EP04-cover.png does not exist in the repository yet. The carousel component only falls back to its placeholder SVG when coverImage is absent/falsy — since this field is set to a non-empty string, the carousel will render a broken <img> rather than the graceful fallback. Consider removing this line until the asset is ready, or add the PNG before merging.

Summary of PR/Issue

• PR feat: add Episode 4 — The Privacy Layer of Personal Intelligence with Ken Liu #32 adds two new content files to publish Episode 4: content/episodes/ep04.md (episode page with frontmatter, intro, timestamps, and references) and content/people/ken-liu.md (guest profile for Ken Liu, Stanford CS PhD student and founder of The Open Anonymity Project).
• All source material was drawn from issue Episode 4 Release #31; the implementation follows existing Quartz content conventions for episodes and people pages.
• The content is accurate — all 17 timestamps, the YouTube video ID, and all three references match the issue verbatim.
• No framework-level changes are made; this is a pure content addition.
• The PR is blocked on one live visual regression and one content pattern deviation that should be resolved before merging.

Review

Content is accurate and structurally sound overall, but two issues prevent a clean SHIP: a broken carousel image (not a graceful placeholder) and a missing "Key Takeaways" section that breaks the pattern established across all four existing episodes.

Issue	Severity	Description
Broken carousel image from non-existent cover asset	WARNING	coverImage is set to a non-empty path that doesn't exist; the carousel bypasses its SVG fallback and renders a broken <img> until the PNG is added.
Missing "Key Takeaways" section	WARNING	All four existing episodes (EP00–EP03) include a ## Key Takeaways section; EP04 skips it entirely, breaking the established content pattern visible to site visitors.
guestOffset field omitted from frontmatter	INFO	EP02 and EP03 explicitly declare guestOffset: 0; EP04 omits it. Functionally harmless (defaults to 0 in the carousel component), but inconsistent with convention.
Ken Liu people page has fewer links than prior guests	INFO	woosuk-kwon.md has three links; ken-liu.md has two. Source material for Ken Liu didn't include additional social links — faithfully reproduced, no action needed.

Progress

• All 17 timestamps verified to match issue Episode 4 Release #31 verbatim.
• YouTube URL format and video ID (rFyHnK7PGrY) are correct.
• [[ken-liu|Ken Liu]] wiki-link syntax matches EP03 pattern.
• ## Appearances on the people page correctly back-links to ep04.
• Tags, episodeId, and date fields all follow existing patterns.
• PR description explicitly acknowledges the missing cover image; the framing ("can be added separately") understates the impact (broken image vs. graceful placeholder).
• No rubrics are defined for this repository — rubrics review returned N/A.

Issue Details

Broken carousel image from non-existent cover asset

Cause: content/episodes/ep04.md line 5 sets coverImage: "/static/covers/EP04-cover.png" but the file does not exist in the repository. The carousel component (EpisodeCarousel.tsx) uses (page.frontmatter?.coverImage as string) || DEFAULT_COVER — the || short-circuits only when the value is falsy. A non-empty string is truthy, so the SVG placeholder is never reached and the carousel renders a broken image.

Candidate solutions:

1. Remove the coverImage line from the frontmatter until the PNG is committed (triggers the graceful SVG placeholder).
2. Add the actual EP04-cover.png to /static/covers/ before merging.

Comments: The PR description acknowledges the missing image but treats it as low-impact. It is not — the fallback mechanism is bypassed entirely.

Missing "Key Takeaways" section

Cause: The episode file goes directly from the intro paragraph to ## Timestamps, omitting the ## Key Takeaways section present in EP00, EP01, EP02, and EP03.

Candidate solutions:

1. Synthesize 4–6 key takeaways from the timestamp labels and issue description (topics available: unlinkable inference, blind signatures, secure inference proxies, OpenClaw, intelligence neutrality, safety concerns with private AI inference).
2. Add a placeholder section to be filled in after the episode is published.

`guestOffset` field omitted from frontmatter

Cause: EP02 and EP03 explicitly include guestOffset: 0 in frontmatter; EP04 does not. The carousel defaults to 0 via ?? 0, so there is no runtime impact.

Candidate solutions: Add guestOffset: 0 to content/episodes/ep04.md frontmatter for consistency.

Recommended Next Step

FIX_PR: Two concrete branch changes are needed — remove or resolve the coverImage reference and add the missing ## Key Takeaways section — both are safe and unambiguous for an automated fix-pr pass.

Final Verdict

MINOR_ISSUES

Action Items

• Fix broken cover image: either remove coverImage: "/static/covers/EP04-cover.png" from content/episodes/ep04.md frontmatter until the asset exists, or add the PNG to /static/covers/.
• Add a ## Key Takeaways section to content/episodes/ep04.md following the EP00–EP03 pattern, synthesizing 4–6 takeaways from the episode material.
• (Optional) Add guestOffset: 0 to content/episodes/ep04.md frontmatter for consistency with EP02/EP03.

[sepo-agent-app]

Sepo pushed fixes for this PR. Branch: agent/implement-issue-31/claude-25303551553. Requested by @lolipopshock.

• Downloaded EP04-cover.png (1920×1080 PNG, 1.7 MB) from the linked GitHub asset and committed it to quartz/static/covers/, resolving the broken carousel image.
• Added ## Key Takeaways section to content/episodes/ep04.md with 6 synthesized bullets covering Unlinkable Inference, Blind Signatures, Secure Inference Proxies, Agent Privacy (OpenClaw), Intelligence Neutrality, and Safety vs. Privacy tradeoffs.
• Added guestOffset: 0 to ep04 frontmatter for consistency with EP02/EP03.

[XenonMolecule]

Not sure if we were leaving the key takeaways or not for the episodes. Any thoughts @lolipopshock ?
