D3's preflight and install recording become the toolchain step: a
bounded run of the item's driver model that makes the build VM and the
project's own files (pins, setup docs, CI configuration) agree, with
the repository as the record. The harness starts it when the VM isn't
set up for the project (and then it edits nothing in the repository);
the driver requests it once work is agreed, and its edits land in the
current milestone. Versions stay facts the harness reads itself; a
rebuilt VM's new host key is trusted only on the operator's word.
D1 gains the rule that until the go-ahead the agent only looks:
anything that changes something is refused by the fast path, so what
the work needs goes in the restatement.
The Development Plan's M4.2 follows: the toolchain step, in place of
recording installs.

A project's trust.merge is operator (the default) or approved (L3, D5,
#65). Set to approved, the harness, never the model, merges a PR in the
PR watch once an approving review from a gitea.operators account is on
its current commit, its checks pass (none at all counts; pending
waits) and it's mergeable; the item then goes on as after any merge.
Each reason to hold off (failed checks, conflicts, a refused merge) is
said once per commit.
Gitea enforces it: protection requires approvals from an operators-only
whitelist and dismisses stale ones. At start, for each approved
project, the agent checks by behaviour that its own unapproved merge is
refused, with a throwaway branch and PR made through the API (never the
workspace); if it isn't refused, the operator merges until a restart.
- gitea: approvals, combined check status, a PR's head commit and
mergeability, API-made branches and their deletion.
- Test and bring-up repositories get the protection.
- Tests: the decision (unit), the hard wall on a real Gitea
(test_trust_live), an e2e test where the operator only approves, and
a walk property, merges_only_approved, checked against a mutant that
ignores which commit was approved.

What the fast path calls unknown is judged by an independent model call
on the item's classifier role (L4), before it runs.
- nisse_dev.loop.classifier: it sees the action and the agreed scope
(project, repository, issue number, the restatement the operator said
go to), built in code; never the transcript, the issue's text, tool
output or the driver's reasoning. Its verdict is a tool call: safe
runs; in_scope runs and is reported in the thread; needs_discussion
asks, as a dangerous action does. An error, no verdict or an unknown
one fails closed. Verdicts are cached per item, agreed revision and
action. A helper is refused what needs discussion.
- action_verdict gains source, model and the classifier's exact input;
details shows the source. An allow after the classifier asked is an
override. scripts/classifier-evals.py exports the judgements from a
store, read-only; tests/integration/classifier_cases.yaml is the seed
set, run per model with --capability-models.
- The fast path's delete rule: deleting on the build VM is contained;
only what breaks the host (system and home directories) stays
dangerous, since in tests the build VM is the test machine.
- The classifier role is the local model in the example config.
- The property walk gains a classifier answering at random, junk and
failures included; dangerous_only_when_allowed now covers its
verdicts (checked against a mutant that runs them all).

Every execution tool call, the driver's and a helper's, gets a verdict
from code before it runs (P3, P4, D6).
- nisse_core.actions, nisse-core's first code: Action and Verdict, and
reading shell commands statically, segment by segment (cd, wrappers,
sh -c). What can't be read that way is unknown; a line is as bad as
its worst command.
- nisse_dev.loop.actions, the rule table: reading, checks and tests are
harmless; workspace edits, local git and installs on the build VM are
contained; pushing, other hosts, uploads, publishing, the forge's own
tools, deleting outside the workspace and wrecking the VM are
dangerous; changing branches by hand is refused (the harness owns
branches) with a pointer to the milestone tools.
- A dangerous call isn't run. The item waits on the operator with a
question rendered from the action, and `allow` lets exactly that
action run once. A helper can't ask, so it is refused and told to
hand back. Unknown actions run, logged, until the classifier (M3.2).
- Every verdict is an action_verdict event, which no model sees, and an
oplog line; `details` shows the counts and every action not simply
run.
- The property walk gains dangerous_only_when_allowed (checked against
a mutant that doesn't use the allow up); the slice e2e checks every
call was judged and none needed an allow.

- A near miss for abandon ("abort", "cancel", "drop it", ...) in an item's
thread is asked about, and changes nothing.
- The driver is told only the operator stops or closes an item, so it
doesn't claim to have done either.
- An issue assigned again after its item closed starts a new item that
notes the one before (Gitea's timeline gives the assignment time);
item_for_issue returns the latest item.
- Abandoning an issue Gitea won't close because of open dependencies says
so, naming them.
- An agreed item isn't offered restate.

- L1: `general`, the scope of conversation not (yet) about a project: an
item per thread, no repository, build VM or execution; closes after a day
idle, a later reply starting a linked item.
- L5: every conversation is an item from its first message; chit-chat is
answered, only work gets a Gitea issue.
- D1: a conversation's record issue is opened once it's work on a project.
The new-project sequence: proposal, a provisioning checklist in Matrix,
verified when the operator says done, a tracking issue carrying the
distilled decisions (not the raw chat), then the architecture PRs.
- Q: a scratch build VM for general replaces the answered question about
records for pure conversations.

- Every milestone branch is cut from the latest default branch: the next
milestone builds on the merged previous one, and a redo after a closed PR
drops the rejected work. Uncommitted work comes along.
- While the item's PR is open, start_milestone is refused, with the PR's
state read from Gitea at that moment, not the last watch round.
- finish_milestone(final): earlier PRs say "Part of #N", the last "Closes
#N"; unsaid, it's final, as before.
- close_item with the item's PR still open waits for the merge (L2: a
closed item leaves nothing open).
- The driver's instructions cover ARCHITECTURE.md and build plans under
docs/plans/ (D2); the harness never parses a plan.
- Parking stashes uncommitted work and pushes it to <item>-parked, put back
on resume, instead of committing it onto the item's branch. The walk
found a half-done review fix parked onto a PR that had merged meanwhile,
where it was lost. Architecture D4's parking line says so.
Tests: unit tests for fresh milestone branches, the merge wait (including
a merge not yet watched), redo after a closed PR, Part of/Closes, close
waiting on an open PR, and the parked-fix regression; the walk's new
milestones_start_fresh property (fork-from-current fails 9 seeds); an e2e
two-milestone feature.

The push credential is either a push-only account's token, handed to git
through a credential helper that names environment variables, never
values, or a deploy key in a short-lived ssh-agent. The remote URL
follows the credential. Configured as gitea.push_user and push_token, or
gitea.push_key.

execution.SSHHost.execute is now the only way the agent runs anything
(L13). Commands travel as a script on SSH's stdin, so the secrets handed
to a call are never on a command line, and every value handed out is
redacted from the output. Timeouts kill the remote process group, and
an unreachable host is reported as such, not as a failed command.
Workspace and GitRepo run on the build VM. The clone uses the
repository's SSH URL, so no credential is stored in it (#89); fetches
and pushes get the push key over stdin, in a short-lived ssh-agent,
and PRs are still opened from the agent's host with its API token.
The bench runs on the build host too.
Tests reach "the build VM" through a throwaway local sshd (nisse_dev
.testing); CI installs openssh-server. The live push test now pushes
with the sandbox's deploy key (NISSE_PUSH_KEY).
Fixes#89.

Each rule is stated once in its home section and referred to by ID

Development-Plan.md section 6, keyed by architecture section. P8 folded

Issues assigned to dev-agent are the intake; the agent restates its
understanding and either proceeds (bug label) or waits for a go-ahead.
Labels steer and are never required. Build plans and ARCHITECTURE.md
are working documents reviewed in PRs, not gates; scope is the issue
and its conversation. Work items can be blocked on Gitea dependencies,
each gets a Matrix thread, milestones are started and finished by
control tools, and the next milestone waits for the previous merge.

Agents run as containers on one stable agent host that keeps their
state and secrets and never runs a command a model chose. Model-chosen
commands run on disposable tool VMs over SSH: a build VM per project
for nisse-dev, its own tool VM for nisse-ops. Secrets are a set per
agent, handed out per operation by the harness and redacted from tool
output. MCP servers stay on the agent host as the one exception.

A model no longer reads another role's turns as its own (#78). The log
stays one record per work item; what a role is shown is projected from
it by Transcript.view() (views.py), which the planner, executor and
helper now build their context from:
- own events unchanged;
- operator messages labelled with their channel, e.g.
[operator, Matrix] or [operator, comment on PR #165];
- orchestrator facts (a new `fact` event) as [orchestrator] statements;
- the executor sees a helper's handback as [helper report], not its turns;
- a helper sees the approved plan and the executor's milestone work as
one-line narration;
- the planner sees no other role's work at all.
The orchestrator now writes facts at the points the models must know
about: work item opened, plan approved or rejected, milestone started,
finished or stopped, published (with PR number and URL) or not, review
comment answered, next milestone, task completed or abandoned.

Development Plan M0.2.
- scripts/bringup.sh: start [REF] sets the previous run aside under
/root/nisse-e2e/runs/, exports the ref under test and starts the agent
as the transient systemd unit nisse-bringup, so it outlives the shell
that started it; stop (SIGTERM, clean shutdown), status, logs, and
collect (the journal log and a readable transcript).
- nisse_dev.dump (python -m nisse_dev.dump STATE_DB [--full]): a readable
dump of a state store's state, pending intents and canonical log. Opens
the store read-only, so it is safe against a live agent.
- The agent runs as root on this development VM, as it will on its own
VM. Architecture D3/D6/D7 corrected to match the operator's intent:
installing packages and toolchains on its own VM is class 2, recorded
so the environment can be rebuilt (it was class 3 with provisioning an
open question); egress names OS package mirrors. The plan's M0.2, M4.1,
M4.2 and bring-up guards follow.
Acceptance: a smoke run started, answered status in the test room,
stopped cleanly, and collect produced the log and transcript.

Development Plan M0.1. Every section reference in code, tests, specs/,
the example config, the tuning guide, and the CLAUDE.md and README files
now cites docs/Architecture.md (P, L, D, O, X, Q) instead of the old
spec's A-H, and docs/Architecture-Build-Spec.md is deleted (git keeps
it). The plan's old-to-new table goes with it.
Mostly mechanical, with a per-site choice where one old section split:
A4 became L2 where it meant stop/abandon/the loop and L3 where it meant
approvals; A10 became L6 in the context-budget code and L7 elsewhere; B2
became D4 for outbound Gitea and publishing and D5 for review intake;
'A3 step N' became the matching step of L8's boot sequence. Comments
describing behaviour the architecture drops (planning always escalating,
thresholds tuned at an old build step) now describe the current code and
point at the Development Plan.
docs/Architecture.md gains one line the rewrite missed: intake outages
delay but never fail work (old B2), now in L5, where the poller and
Matrix code cite it.
Comments and docs only; no behaviour change.

docs/Development-Plan.md: where the code stands against each section of
docs/Architecture.md, the environment today, how we work (plan-first per
milestone, tests, the Quint model, a bring-up run on this box ending
each phase), and seven phases of milestones from housekeeping to
nisse-ops, each marked pre-approved or needs discussion. Every open
issue is mapped to a milestone or marked superseded; an old-to-new
section table serves the reference update in M0.1.
docs/Architecture.md: status now agreed; D7 regains the browser tool
for the internal test network, left out of the rewrite by mistake.

A full rewrite of the architecture, following the outline agreed with the
operator: a threat model of mistakes, injection and crashes rather than a
malicious model; actions classed by their effects; hard walls, a
deterministic fast path and an action classifier; a conversational loop
driven by a local model with frontier helpers; approvals as scoped
permissions with pre-approved milestones and a trust dial; context and
memory, including agent memory; documents as nisse-dev's workflow.
Added beside docs/Architecture-Build-Spec.md, which stays until this is
agreed; the Development Plan and reference updates come after. New
section letters (P, L, D, O, X, Q) avoid clashing with the old A-H
references in the code meanwhile.
