Two additions the article does not have, both found by running it: - psalm-baseline.xml is diffed after the tools pass. Psalm exits 0 on a suppressed finding, so without this the gate green-lights a worker that "fixed" static analysis by widening the baseline. - vendor/ is provisioned into a fresh worktree by hardlink copy from the primary checkout. vendor/ is gitignored, so every tick would otherwise die 127 before running a single test. Composer's path repositories are relative symlinks, so the copy resolves against its own worktree and tests the branch's src/ — verified, not assumed. CHECK 2: the conductor invocation physically cannot write. Asked a model with --allowedTools "Read,Grep,Glob" to write a file: the attempt is recorded in permission_denials and no file appears.

Three departures from the article, each forced by what is actually installed: - There is no `llm` CLI here, so every seat is `claude -p --model`. One CLI, no new dependency, and the seats are variables so a model outage is a config edit rather than an incident. - `claude -p` has no --max-tokens flag. Dropped; the CLI manages the ceiling. - The CLI reports total_cost_usd per call, so log-cost.sh records real dollars instead of the article's token-arithmetic estimate. thinking_tokens and cache_read are still logged: the first is where surprise spend hides, the second is the only proof the cached-prefix ordering still holds. One check the article does not have. The read-only wall holds, but silently: a denied Write returns stop_reason "end_turn" and a cheerful message about having requested permission, so nothing in the happy path notices. loop.sh now reads permission_denials and stops the tick (exit 4) when the conductor reaches outside its seat — that is either injection or drift, and neither should have its decision acted on. The trust tier table in the source is a published image. Only the top row survives as text (auto = 20 runs at 95%); the watch/queue thresholds are this repository's own, and trust-log.sh says so where they are defined. CHECK 4: 21 passes -> auto; two fails -> watch, with ALERT demoted in STATE.md. CHECK 5: goals with predicate true and false -> exit 1, exactly one flipped.

Quorum, ratchet and red team ship as written conditions with the reason each is not installed here — the article's rule is that a loop whose condition you cannot state should be uninstalled, and three uninstalled loops with triggers beat three installed ones nobody can justify. The runbook maps every exit code and every ALERT line to a response. Its rows come from contract.md's "pages me" list and loop.sh's exits; the article's own runbook table is a published image. Cron ships as text in the runbook. Installing a crontab is a decision, not a side effect of a merge. WA007 records the decision, the seats, the rollout, and one exception that needed writing down rather than assuming: loop/* branches are exempt from the prise registry, because a loop that opens and abandons draft PRs would either churn main with prise commits or fill the registry with stale entries.

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.

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.

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.

All three were mine or the article's, none were the model's: - log-cost.sh died on every call. "${3:-{}}" reads as a sane default but bash closes the expansion at the first brace, so jq received the envelope with a literal "}" appended and exited 5 after already emitting its line — killing the tick just before the conductor's cost was logged. - Both seats intermittently fence their output in markdown. Unfenced, a fenced "QUIET" never equals QUIET, so a quiet repository wakes the expensive seat on every tick; and a fenced work order dies in jq. The prompts ask for bare output, but a prompt is an instruction, not a guarantee. - Gating execution on the `auto` tier deadlocked the ledger: a skill reaches `auto` by accumulating runs and can only accumulate runs by executing. What the tier gates is the PR, not the attempt — below `auto` the work still runs in a throwaway worktree and the branch is left for a human, which is what weeks 1 and 2 of the rollout describe. CHECK 3: a hand tick now exits 0, logs triage and conductor cost lines, and writes one dispatch row. The conductor queued a contract-sensitive item rather than acting on it. Cache reads dominate conductor input (54127 cached against 4 uncached), which is CHECK 6's caching criterion visible on the first tick. Gate, both directions: a planted CS violation is rejected (exit 8); a widened psalm-baseline.xml is rejected; a clean tree passes both guards silently. The two goals are born from this branch's own finished work, and each predicate was tested against the fixed and the broken state as Layer 5 requires — padding CLAUDE.md past 150 lines and pointing the gate at a non-existent composer script both flip their goal to VIOLATED.

First live run of the execute path, with these fixes in: conductor chose execute, the worker went off-spec and wrote an IMPLEMENTATION.md instead of touching the target file, and the fresh-context verifier caught it — "the diff does not touch the target file at all".
