Browser History ACSet

Trit: 0 (ERGODIC - information coordination)

Overview

Unified categorical structure for browser history across:

• ChatGPT Atlas (Chromium-based)
• Chrome, Arc, Brave, Firefox, Safari

Uses GF(3) trit classification for browsing behavior analysis.

Path Equivalence Tests

Verified cross-language compatibility between Python and Julia:

Operation	Python (PyACSet)	Julia (ACSets.jl)	Match
nparts(A)	2	2	✓
subpart(1, :f)	1	1	✓
incident(1, :f)	[1]	[1]	✓
path 1→f→g	1	1	✓

Key Operations

# Python (PyACSet)
url = acset.subpart(visit_id, "url_of")
domain = acset.path(visit_id, "url_of", "domain_of")
referrers = acset.incident(url_id, "url_of")

# Julia (ACSets.jl)
url = subpart(acs, visit_id, :url_of)
domain = subpart(acs, subpart(acs, visit_id, :url_of), :domain_of)
referrers = incident(acs, url_id, :url_of)

Specter-Style Navigation

# Select all visits to github.com
github_visits = (
    SELECT(ALL("Visit"))
    >> FILTER(lambda v: acset.path(v, "url_of", "domain_of") 
              and acset.subpart(acset.path(v, "url_of", "domain_of"), "domain_name") == "github.com")
)

# Transform: add trit to all URLs in domain
TRANSFORM(
    SELECT(ALL("URL")) >> FILTER(lambda u: acset.subpart(u, "domain_of") == d1),
    lambda u: acset.set_subpart(u, "trit", 1)
)
