# shared/ — framework-neutral core
# portfolio-optimiser-commons
This directory holds the parts of the project that are **independent of any AI agent
framework** and are meant to be **shared, unchanged, between both reference
implementations**:
Framework-neutral shared core of the portfolio-optimiser method: the normative specs, example bundles and golden fixtures vendored by both reference implementations.
- **this repository** — the method built on Microsoft Agent Framework (MAF);
- **a sibling repository** (built later, in sequence) — the same method on the
**Claude Agents SDK**.

Sharing one identical core is what makes the two implementations a *fair comparison*:
both consume the same concept, the same example data, and the same expected outcomes,
so the only thing that differs is the agent framework itself.
This repository is the **source of truth** for everything in the portfolio-optimiser method
that is **independent of any AI agent framework**. It holds no runnable code — only
normative specifications, example data, and expected outcomes.
## Contents (growing)
Two reference implementations consume it, unchanged, as a `git subtree` at `shared/`:
- [`CONCEPT.md`](CONCEPT.md) — the business concept, written for a non-specialist
(e.g. a business developer at another company).
- [`portfolio-optimiser`](https://git.fromaitochitta.com/open/portfolio-optimiser) — the
method on **Microsoft Agent Framework (MAF)**;
- [`portfolio-optimiser-claude`](https://git.fromaitochitta.com/open/portfolio-optimiser-claude)
— the same method on the **Claude Agent SDK**.
Sharing one identical core is what makes the two implementations a *fair comparison*: both
consume the same concept, the same example data, and the same expected outcomes, so the only
thing that differs is the agent framework itself. The second implementation is built from the
specifications alone, without reverse-engineering the reference code.
## Contents
- [`method-spec.md`](method-spec.md) — the **normative method specification**, framework-neutral
(the prose never names a concrete agent toolkit — enforced by a guard test): the 8-step loop,
the verdict JSON contract, the inbox/outbox folder contract, the promotion-gate semantics, the
IR projection + golden suite as the only ground truth, and the budget/provenance requirements.
- [`ingest-spec.md`](ingest-spec.md) — the **normative ingest specification**, framework-neutral
(same guard rule): the deterministic ingest step that materializes real data sources as OKF
bundles BEFORE the loop — the polymorphic manifest schema (file/CSV, SQL, HTTP as extension
point), the credential-reference rule, the verdict-layer reservation, the ingest provenance
frontmatter with an explicit timestamp, the index-generation requirement, and the
golden-extraction format.
- [`CONCEPT.md`](CONCEPT.md) — the business concept, written for a non-specialist (e.g. a
business developer at another company). Written in Norwegian.
- [`examples/bygg-energi-mikro/`](examples/bygg-energi-mikro/) — the first example knowledge
bundle (OKF / LLM-wiki): one office building, one LED-retrofit measure, with a seed expert
verdict encoding the realization gap and a golden-suite of expected validator outcomes. A
small **dev fixture** for exercising the agentic loop; a realistic full-scale example comes later.

## Rules
## Vendoring this repository
- **Nothing in here may import or depend on a specific agent framework.** If it does,
it does not belong in `shared/`.
- **Repo layout (decision R1, realized 2026-07-03):** the shared core lives in its own
repository, [`portfolio-optimiser-commons`](https://git.fromaitochitta.com/ktg/portfolio-optimiser-commons)
— the **source of truth**. Each implementation repo consumes it as a **git subtree**
at this unchanged `shared/` path (so tests and the `PORTFOLIO_SHARED_ROOT` default
resolver are unaffected). Do not edit commons content anywhere else without syncing.
This repository is **vendored, not installed** — there is no package to add. Each consuming
repository carries it as a `git subtree` under `shared/`, so the specs and fixtures are present in
a normal checkout with no extra tooling.
## Subtree sync (pull-only — run from the consuming repo's root)
Register the remote once, from the consuming repository's root:
The remote is registered as `commons`
(`ssh://git@git.fromaitochitta.com/ktg/portfolio-optimiser-commons.git`).
```sh
git remote add commons https://git.fromaitochitta.com/open/portfolio-optimiser-commons.git
git subtree add --prefix=shared commons main --squash
```
**All edits land in commons first** (clone it, commit, push there), then each
consuming repo pulls them in:
Then pull updates with:
```sh
git subtree pull --prefix=shared commons main --squash
```
**Never run `git subtree push` from a consuming repo.** Observed 2026-07-03: because
this repo's history contains commits that create/delete the `shared/` prefix, the
push re-split leaked the consumer's *entire* history into commons (cleaned up by
force-push the same day). Pull-only keeps commons the clean source of truth.
**Sync is pull-only. All edits land here first** — commit and push in this repository, then pull
them into each consumer.
See the target picture for the full architecture: `docs/plan/2026-06-26-maalbilde-agentic-loop.md`.

## Non-goals
- **Not a runnable system.** No pipeline, no CLI, no package. The specifications describe
behaviour; the two implementation repositories provide it.
- **No framework dependency.** Nothing here may import or depend on a specific agent framework.
If it does, it does not belong in this repository — that is what "framework-neutral" buys, and a
guard test in each consumer enforces it for the two normative specs.
- **Not a general-purpose knowledge-format standard.** The bundle layout follows the upstream Open
Knowledge Format where it applies; this repository does not seek to replace or extend it beyond
what the method needs.
- **Not a home for implementation decisions.** Anything true of only one of the two stacks belongs
in that stack's repository, not here.
- **No inbound patches through this forge.** See [CONTRIBUTING.md](CONTRIBUTING.md).
