**Status:** Concept and specification only (Stage 0). Not production legal text. Do not attach TRSL to production software yet.
The **Target Revenue Framework (TRF)** is a phased software monetization system: a defined development **Phase** accumulates **Development Credit** and **Remission Credit** against an immutable **Initial Target** until the **Milestone Release** automatically converts to a permissive **Future License** (MIT or Apache-2.0). A **Trust Service** publishes manifests, ledgers, extensions, and attestations as factual evidence — it does not decide conversion.
> Commercial beneficiaries fund the creation and early availability of a software improvement; once the declared target is satisfied, the governed release becomes permissively open source.
## Terminology guardrail
Before conversion, software under TRSL is **source-available** with commercial-use restrictions. It is **not** Open Source under the [OSI Open Source Definition](https://opensource.org/osd) (field-of-endeavour non-discrimination). After the Conversion Event, the Milestone Release is available under the declared OSI-style Future License.
**`spec/` vs `specs/`:** The concept document predates the plural `specs/` directory and remains under `spec/` so history and cross-references stay stable. New product/tech artifacts go under `specs/`. Do not move the concept file without a deliberate migration note.
- A finalized degeneration formula (research + working defaults only)
- That any real product Phase is governed by TRF today
