Build logthis is day one - read it as that.

Concept site published: landing page, whitepaper, avatar and banner assets, in the register/ledger visual system.

Pulled 251 real trading days of Coinbase (COIN) daily close/high/low/volume from Yahoo Finance's public chart API - see sim/coin-daily.csv.

Built sim/mycel-sim.js: a deterministic, seeded implementation of the Sense / Grow / Reinforce / Prune / Reroute / Fossilize mechanism, run against the real COIN dataset above.

Replaced every invented statistic on the landing page and whitepaper (connections, reroute time, prune counts) with the simulation's literal output. See Reproduce this.

Published explorer.html - the full 251-day simulation record, rendered directly from sim/fossil-record.json.

Published verify.html - SHA-256 hashes of the core documents, checkable in-browser or offline.

Added an explicit non-affiliation notice: MYCEL is an independent concept project, not built or endorsed by Robinhood Markets, Inc.

Site deployed for real: mycelrh.github.io/mycel, via GitHub Pages.

Live COIN·USD volume chart on the overview page, plotted straight from sim/coin-daily.csv with GROW/REINFORCE/PRUNE events marked at the day they happened.

Safety checklist panel on the overview page: no contract, no sale, no wallet-connect, source public, figures reproducible - stated plainly instead of left implicit.

.github/workflows/update-sim.yml: a daily job that refetches real COIN data, reruns the simulation, and commits the result if it changed. First manual run succeeded and found real new data to commit - see the commit history.

Every hash pinned on verify.html was wrong from the moment it launched: Windows' line-ending conversion meant the local files used to compute them (CRLF) didn't match what the repo actually stores and serves (LF), so the page would have reported "changed" on files nobody had touched. Added .gitattributes, disabled autocrlf for this repo, and re-pinned every hash against the real served bytes - confirmed matching live with the page's own Check now button.

$MYC token development has begun. No contract is deployed yet, and nothing on this site changes as a result - no sale, no presale, no wallet connection. The whitepaper's $MYC token section and the site's status line now say so plainly.
