Evidence, not marketing.
Every article on this page links to its source evidence — an ADR, a test run, or a design decision. No fabricated scores. No invented certifications. No AI slop.

What we write about
Three subjects, and a rule about all of them.
The rule is that a post has to be adapted from something already in the repository — an architecture decision record, a test run, a design document. That constraint is what keeps the writing narrow, and it is why there are five posts here rather than fifty. If a claim in one of them sounds surprising, the source link at the bottom of the post is the place to check it rather than take our word.
Engineering
2 postsHow the store is built: the bi-temporal model, and the test suite that gates it.
Trust
2 postsWhat the system refuses to do — abstain rather than guess, and bind a scope it cannot later widen.
Continuity
1 postMoving a session between tools without losing the record of how it got there.
Illustrative example — not live data
Articles
Writing about what we actually shipped.
Each post is adapted from a source document in the repo. If a claim sounds surprising, the source link at the bottom of the post is the place to check.

Why Zephr says 'not evaluated' instead of guessing
Trust over fluency: when evidence is missing or contradictory, the system stops rather than fabricate.

How TrustBench tests AI memory like software
Deterministic scenarios, a single measured feature, and an honest list of what we have not evaluated yet.

Read the security model.
git clone https://github.com/DigitalSoftDistribution/zephr.gitThe documentation covers the architecture, tool contract, TrustBench methodology, and trust model in detail. Every claim links to its source.
