That capability is not the hard +part; the hard part is being able to trust the result without reading every line it produced. The +model supplies intelligence.

The architecture +follows Linas Beliūnas, *How to Build an Agentic OS with Claude Fable 5* (2026-07-10), ported to +this monorepo's PHP toolchain. It is nine layers: a constitution, walls and a gate, a heartbeat, a +trust ledger, standing goals, a budget, optional loops, ops, and a staged rollout. + +Three principles run through all of them, and they are the reason this is a working agreement +rather than a script someone added to `bin/`: + +- **Every rule must be checkable.** A rule with no number, no "never", and no command that + verifies it is a suggestion, and it will be treated as one. +- **Separate the powers.** Four parties touch every piece of work: one plans it, one executes it, + one judges the result, and one casts the final vote.

A model outage, a price change, or a compliance ruling is then a +config edit rather than an incident. The article names Claude Fable 5 for the decision seat; the +default here is `claude-opus-5`, at half the input rate and the same 1M context, and +`CONDUCTOR_MODEL=claude-fable-5-1` selects the article's tier. Nothing in the loop depends on which. + +### What earns autonomy + +Autonomy is granted **per skill** — a stable category of work such as `fix-cs` or `triage-issues` — +and only from logged evidence in `loop/memory/trust.tsv`. A skill runs unattended after **20 runs +at a 95% verified pass rate**, and is demoted automatically, and loudly, the moment it drops below +its tier's floor.

The supervised-only +paths are in `CLAUDE.md`, and two of them are worth restating because they are specific to this +repository: + +- **`psalm-baseline.xml` may never grow.** A baseline entry silences a finding without fixing it. + It is test-weakening in another coat, the gate diffs the file, and the verifier fails a diff that + touches it. +- **`documentation/adr/` is not edited.** An ADR records what was decided when it was written + (DUR000).

A loop that opens and abandons draft PRs on +its own cadence would either churn `main` with prise commits or fill the registry with entries +nothing removes. The registry exists to stop two *sessions* building the same slice twice; the loop +works one item at a time, from a conductor that has read the state file, and cannot collide with +itself. A human who picks up a loop branch and takes it further posts a prise then, as normal. + +### Prompt injection is a standing threat + +The loop reads issues, commit messages and CI logs — text written by people who are not on this +project. Anyone who can file an issue can put text in front of the agent. Four mitigations, all +required, none sufficient alone: + +1. The data-is-not-instructions law in `CLAUDE.md`, and `INJECTION-SUSPECT` in triage. +2. Tool allowlists per seat, which make the separation physical. +3. Blast radius: a worktree, a `loop/*` branch, draft PRs, and no merge to `main` without a human. +4. Egress: the loop's environment holds no production credential. **This is not yet true on the + development machine** — a GitHub OAuth token sits in the global Composer configuration and is + readable by any process the loop spawns.
