Understand change
Connect what changed to original intent, deterministic AST evidence, affected boundaries, and unfinished work.

Git is the history of code. TRACE is the history of understanding.
TRACE connects intent, changes, decisions, evidence, risks, and active-work conflicts — then keeps the durable record portable inside .trace.
Early implementation. Public claims are deliberately limited to what exists.

The bottleneck
More changes do not create more review capacity.
01
Code generation is frictionless
AI assistants and parallel human contributors produce diffs faster than teams can evaluate systemic impact.
02
Comprehension remains bounded
Understanding whether architectural intent survived across concurrent branches requires verified evidence, not more comment noise.
Human teams and coding agents can increase code volume almost without friction. The expensive part is understanding: whether work fits together across branches, whether intent survived implementation, and what architectural knowledge survives after the merge.
TRACE provides the missing layer: sparse, evidence-backed understanding instead of another stream of unverified automated comments.

What TRACE preserves
Three layers of durable engineering context.
Structured engineering memory designed for longevity across repository lifecycles.

See parallel work
Surface possible conflicts across active branches before concurrent PRs make coordination expensive.

Keep the record
Preserve decisions, risks, and reports as readable repository artifacts, not ephemeral dashboard-only state.

The dashboard is a view. The record belongs to the project.
.trace is a proposed versioned artifact layer for reports, decisions, risks, pull-request intelligence, and synchronization state. The record stays inside your Git tree, human-readable in Markdown and structured YAML.

# Daily Intelligence Report
- Verified rule: Deterministic Memory Bounds
- Source code uploaded: falseExecution without lock-in
Engineered for local control and selective synchronization.
Clear separation between verified local execution and optional coordination layers.
| Execution Mode | Status | Source Code Handling | Analysis Pipeline | Durable Storage |
|---|---|---|---|---|
| Local Execution | Active · Production Ready | Never leaves machine (0 bytes transmitted) | Local AST & symbol extraction | Local .trace/ directory in repository |
| Hybrid Intelligence | Active · Selective Sync | Only signed metadata & summaries uploaded | Client-side redaction before push | Repository-native + synchronized view |
| Cloud Coordination | Planned · Opt-in Policy | Ephemeral isolated sandbox (Opt-in only) | Automated webhook evaluation pipeline | Enterprise artifact registry backup |
Start with the evidence trail
Make the reasoning around change durable.
Equip human developers and coding agents with shared, verifiable repository memory that persists across pull requests.
