Status pills: releasing (public release in progress), private (may open), planned (release planned), internal.

| Project | Status | Language | License | What it is |
|---|---|---|---|---|
| Research library | private, in daily use | Python | n/a | A verified research corpus and the pipeline that keeps it honest: 4,000+ reports, nearly all carrying a current verification review, re-checked on a staleness schedule, with a citation guard that rejects fabricated sources. Facts go quietly wrong over time; a library that re-verifies itself is worth more than a bigger one that does not. |
| Sextant | releasing | Python | Apache-2.0 | Local-first AI memory and orchestration: an MCP memory server with 30 tools, a temporal knowledge graph, a task queue and scheduler, and a memory that re-verifies its own stale facts. 4,000+ automated tests, CI on Linux, macOS and Windows. |
| epistemic-decay | private, may open | Python | stated per repository | The confidence-decay model and re-verification behaviour from Sextant as a standalone package. |
| inspiration-engine | private, may open | Python | stated per repository | Semantic-entropy self-consistency plus a verify-before-promote gate. Treats a model's variance as candidate ideas instead of trusting the first draft. |
| rpo-guard | private, may open | Python | stated per repository | Catches the two silent failures of a personal backup: a missed recovery point and a disk that quietly filled up. Born from a real backup-loss event. |
| TUI suite | planned | Python, Textual and Rich | stated per repository | A set of terminal apps on a shared base library. |
| gatekeeper | private | C, Python | n/a | A Windows-first local security control plane: application-control (WDAC) policy workflows with a fail-closed gate in front of automated actions; a kernel minifilter is in development. |
| Lookout | private | Python | n/a | An availability watcher that learns restock patterns. No anti-bot evasion and no automated checkout, by design. |

Licenses: Sextant is Apache-2.0; every other repository states its own license when it opens.

## Contributing (when repositories are public)

Open an issue before a PR, even a small one. Match the existing style: plain English, plain code, no clever DSLs. One change per PR. I read everything and aim to respond within a week.
