Date: 2026-09-28 (America/New_York). Owner: Boris Mizhen. State: publication and listed profile changes live-verified in the authorized browser session; remaining checks are explicitly open below. This is an operational record, not a product-performance claim or a production deployment receipt.

Source and authorization

The owner specified verbatim copy and approved saving/publishing in the conversation. The six supplied text blocks were compared with the corrected Drive kit before publication:

LinkedIn_Posting_Kit_2026-09-28.md, Drive file 1QRzLMTNY4x1VFbcZIwYxjHAeamnckqD9.
Required last line: Explore the pilot: https://mizoki3.com/media/pilot.

The existing current employer was Media Intelligence.ai, not Media Intelligence LLC. The owner explicitly approved updating that existing entry to Founder and CEO while retaining the employer, dates, location and employment type. Do not rename the company to match the original prompt.

The owner later expressly instructed: keep all existing Featured items and certifications; remove none (2026-09-28, 18:02 America/New_York). The earlier question about removals is resolved. Do not ask it again or infer permission to delete from a future general clean-up request.

Completed profile changes

Item	Verified result
Quiet edits	Share profile updates was already Off; it remains Off. Experience Notify network was also Off when saved. Previous value to restore, if requested: Off.
Banner	Exact approved banner uploaded and saved.
Headline	Exact kit headline saved, beginning `Founder, MIZ OKI 3.5 · Causal Growth Control for growth teams`.
About	Exact kit text saved; editor text equality checked before save.
Top skills	Decision Intelligence; Marketing Measurement; Causal Inference; Performance Marketing; AI Governance.
Additional skills	Incrementality Testing; E-Commerce (LinkedIn catalog spelling); Product Strategy; Artificial Intelligence (AI); Entrepreneurship. Follow-skill controls were unchecked before saving.
Experience	Founder and CEO at Media Intelligence.ai; exact kit description, including `is designed to keep` and the Intent Engine v2 preview qualification. Preserved Full-time, November 2024–Present, New York, United States, Hybrid. Saved state and success notice observed.
Contact websites	Existing Company entries `mizoki3.com` and `Mizoki3.com` retained; added `https://mizoki3.com/blog` as Blog and `https://decisionstudio.mizoki3.com` as Portfolio. LinkedIn accepted four slots. Other contact fields were untouched.
Featured links	Four cards saved with exact requested titles/descriptions. Observed order: series, demo, pilot, Decision Studio, then the existing items.

Featured cards:

The Next Dollar: nine founder letters — submitted https://mizoki3.com/blog#the-next-dollar; LinkedIn generated the saved destination https://mizoki3.com/blog, removing the fragment.
MIZ OKI Media executive demo — https://mizoki3.com/media/demo.
Design a 90-day pilot — https://mizoki3.com/media/pilot.
Decision Studio — submitted https://decisionstudio.mizoki3.com/; LinkedIn normalized the trailing slash.

Preview generation initially failed and left Save disabled. A later ordinary retry succeeded for each card. Do not equate a preview error with a published card or keep adding duplicates after success.

Earlier in the same conversation, before the final verbatim launch instructions, the Project title/description were updated to MIZ OKI 3.5 — Operating Knowledge Intelligence. The public-profile view later showed that state. This is a separate earlier edit, not a change made during this documentation closeout.

Letter 1 content and checks

Audience was Anyone; no scheduling was used. Exact approved copy, the square graphic and the first comment were published. No other posts were commented on or reacted to.

Alt text entered and verified before publication:

Cover for founder letter 1 of 9: 'The next dollar needs a decision.' Below it, a capture of the mizoki3.com homepage: 'Know why performance moved. Put the next dollar where it creates profit.'

The published image viewer displayed the intended graphic, but did not expose the stored alt-text value for independent post-publication verification. Keep that limitation separate from the verified pre-publication entry.

First comment, observed after posting:

Read the full letter: https://mizoki3.com/blog/the-number-your-bank-account-reports

Try the Media executive demo: https://mizoki3.com/media/demo

Both destinations loaded in the browser. The linked demo exposed the internal codename; no website copy or service was changed in this LinkedIn task.

Audit observations — unchanged

These are existing profile/content claims observed during the review, not verified business results:

Older Activity includes 50–75× decision velocity, 2.3× faster growth, 73% cost reduction and 50% marketing-budget waste wording.
Zeta experience states monthly revenue grew from $1M to over $30M. Media Network experience states growth to over $40 million in early revenue. Digital Contact says record growth and sale to Jns Capital.
Two Media Network executive entries overlap in 2004–2012, with different locations and slightly different start dates. They may be intentional; no consolidation was performed.
Recruiter-only Open to work remains enabled. Merchant Commerce text contains apparent spelling errors. These need an owner decision before edits.
Four machine-learning certifications remain: Advanced Learning Algorithms; Machine Learning Specialization; Supervised Machine Learning: Regression and Classification; Unsupervised Learning, Recommenders, Reinforcement Learning.
No prohibited legacy wording or guarantees were found in the profile sections inspected. This is bounded to inspected content, not a historical-all-posts certification.
Existing Featured items retained: Knowledge Graphs; Mergers & Acquisitions (M&A); BGI; Startups; Deep Learning; the four certifications above; Applying science and technology to innovate online media buying strategies.; Marketing.

Remaining work and exact continuation boundaries

Item	State and next action
Letter 1 first position	Featured status confirmed; the reorder list omitted the post while showing the link cards. First position was not verified. Inspect the existing post/profile in a supported UI; move the existing item first if available. Do not repost or delete retained items.
Series anchor	LinkedIn removed `#the-next-dollar`. Investigate whether the existing Featured card can retain the requested fragment. Do not silently claim exact-URL parity or edit the website to compensate.
Published alt text	Pre-publication entry verified; stored value not exposed afterward. Inspect the existing image's alt-text control if available without creating another post.
Cleaner public URL	`boris-mizhen` was entered in the editor only to check availability. No availability response appeared before Save. Cancelled without saving; current URL unchanged. Availability remains unknown, and any actual URL change needs the owner's decision.
Claude tracker	`https://claude.ai/artifact/TfYKAr3V2RpERHtAhiGUVh` remained behind Cloudflare security verification in this browser. Skipped as the owner permitted; no tracker checkboxes or database fields were written. Do not bypass the challenge or mark the entire profile complete. When legitimately accessible, tick only completed checklist items, mark Letter 1 Posted and First comment added, and record the post URL above.
Later letters	Next planned kit date is Letter 2, Thursday 2026-10-01; later dates remain planning information only. Obtain the owner's publication instruction for the next letter; do not schedule or post Letters 2–9 under today's Letter 1 approval.
Journal backlink	The playbook describes linking a published article to its LinkedIn discussion. No site file was edited or deployed here. Treat a future backlink as a separately governed website change/release.
Existing profile audit issues	Owner decisions remain pending; retaining Featured items is already decided.

Documentation delivery and limits

The closeout is recorded through the governed claude_memory.py record path, linked from the active Journal memory and memory index, and represented in cross-repository shared memory. Detailed report and concise memory must distinguish review-branch publication from integration into protected main.

This session has no general ChatGPT personalization-memory write tool. Repository/shared-memory writes and the saved report are the durable records; no claim is made that ChatGPT's private memory settings were changed. Google Drive clone parity is not claimed without a fresh canonical checksum receipt. No credentials, codes, private contact data, session tokens or browser safety URLs are included in these records.

Validation and publication receipt (documentation closeout): shared-memory main advanced from c17f73a3f1461f3ca6d31a94c9d7df770f003847 to 5551a86f1fb307e9a1678961dddc94b8a5dbaf55; new launch record read back exactly. Shared-memory doctor: 160 records, zero findings, index current. Claude memory strict validation passed; memory unit tests 26 passed and memory-governance contract tests 7 passed. These are documentation-system checks, not product-performance measurements. Repository edits are prepared on mem/linkedin-letter1-closeout-20260928 for protected-main review; no site deployment is included.
