M4.1: toolchain preflight
A model works out and sets up what a project needs on its build VM; code makes sure that happens, bounds it and checks the result (D3). - Before each driver run on a project, one round trip checks the build VM: the harness's own baseline (missing: the item waits, a template problem), the workspace clone (missing: cloned again and said; the item resumes from what it pushed) and a per-project marker. - No marker (a new project, a new or wiped VM): the item's driver model runs a bounded preflight first, with its own prompt, the execution tools (screened as ever) and toolchain_ready. The harness runs each reported version command itself (version-shaped commands only, even from the marker, which the model's commands could edit) and writes the marker. Gaps and an unfinished preflight are facts and work goes on; the thread hears only of installs and gaps. A rebuilt VM starts from the last toolchain. - Later runs check the versions again; a change is a fact and a thread line. The PR body says what the work was tested with. - A changed host key is its own failure (HostKeyChanged): the item waits for the operator's `trust new host key`, which drops the pin; then the VM is set up again. - A prompt line: install what the work needs on the build VM, say why, and put lasting needs in the project's own pins. - tuning.preflight: max_turns, command_timeout_s. - The property walk gains a VM wipe and ready_before_work (checked against a mutant that skips preflight); parked_work_safe accepts that a wipe loses what wasn't pushed (D3).

M2.8: switch over to the new loop
nisse-dev now runs only the conversational loop. The gated state machine it was built alongside is gone: - Removed control.py, planner.py, executor.py, approvals.py, gates.py (command_form moves to loop/reader.py), publish.py and poller.py, the old assembly in agent.py (its shared helpers move to loop/build.py), the store's state-machine view (get_state, transition), their tests, the old end-to-end and live planning/milestone/gate tests, and specs/orchestrator.qnt with its scenarios. - Roles are driver, helper, expert and classifier; driver is required. loop:, roles.planner, roles.executor and tuning.executor are refused with what to use instead; tuning.driver takes the turn cap and failure limit. - The benchmark and the capability matrix measure the driver: the loop's own system prompt and tools, the task's plan as the agreed restatement. Task plans end with finish_milestone, so earlier runs show as (old); stored runs' executor tuning reads as the driver's. - A delegation on the loop records what its helper's alias resolved to (L9), as the old path's did. - The dump shows a work item's revision and what it waits for. - Behaviour the old tests covered and the loop shares stays covered: driver runs that fail on a model call, stop mid-turn, reset the failure count; go-aheads ignoring case and punctuation; a request too big to fit is never sent; the assembly tests, now on build_loop_agent.

Run every command on the build VM over SSH (M1.3)
CI / checks (push) Skipped
CI / checks (pull_request) Failing after 55s
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.

Retire the old build spec, and point every reference at the architecture (M0.1)
CI / checks (push) Skipped
CI / checks (pull_request) Successful in 1m22s
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. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01PPQ14L3LikyefCMFBqEbKE |

Fit every model request to its context window
CI / checks (push) Skipped
CI / checks (pull_request) Successful in 55s
Every turn re-sent the whole transcript with nothing checking it against the model's window. On a local model that fails silently: Ollama drops the start of an over-long prompt, which is where the system prompt and the plan are. Measured on the Jetson's llama3.2, cut at 4096 tokens with no error. - The model catalog reads max_input_tokens and max_output_tokens from LiteLLM's model_info, and startup refuses a role on a model with no declared window - BudgetedClient wraps both routes. It fits the canonical events before rendering: older tool results cut to head and tail, then the oldest turns dropped with a note, keeping calls with their results; a request that still cannot fit fails with ContextOverflow and is never sent. The output ceiling is the smaller of config and the model's limit - Tokens are estimated from characters, pessimistically, and the estimate is corrected from reported prompt sizes, only ever upward - The executor takes its scope from the log: the latest plan, which is the approved milestone plan, goes in its system prompt, and it sees only events after it - Tool output keeps its head and, mostly, its tail, so a test runner's failure summary survives truncation - tuning.context.keep_recent_turns and safety_margin are new knobs - scripts/probe_context.py checks a declared window against what the server does; it confirmed llama3.2 cuts at the declared 4096 - The tuning guide covers the budget, declaring a local model's limits, and the probe Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> |

Move configuration to a YAML file, and make the tuning knobs configurable
CI / checks (push) Skipped
CI / checks (pull_request) Successful in 51s
The thresholds Part H says to tune on the real inference hardware were hardcoded, so every adjustment would have been a PR. They now live in a `tuning:` section of a YAML config file, which also replaces flat environment variables as the home for structure (#32). - The file (NISSE_CONFIG, default ./nisse-dev.yaml) carries structure and holds no secrets: credentials are ${VAR} references resolved from the environment, and a reference to an unset variable is an error - The environment still wins: every existing NISSE_* variable overrides its key, and the file is optional, so .env and CI work unchanged - Validation stays fail-fast and reports every problem at once; unknown keys are errors, so a misspelt knob fails at startup instead of silently doing nothing - The config file joins the state store and .env in the check that refuses to start when they sit inside the workspace clone - Tuning covers the executor's turn and failure limits, the consult budget, the delegation caps, the command timeout and the tool output limit, which Workspace now takes as a setting; the defaults are the values the agent already ran with - llm.max_output_tokens reaches both LLM clients from the config docs/Tuning-Guide.md explains the knobs for someone learning local model tuning: how weights, quantization and the KV cache spend VRAM, what each knob does and what goes wrong at either extreme, and an order to tune in. nisse-dev.example.yaml documents every key and is checked by a test so it cannot drift.

Add the delegation harness (A13) — step 7b
A frontier model receives a scoped sub-task, works autonomously with full tool access, and hands back; the local loop reads the handback note and the file state, never the reasoning. - Branch at delegation start, and abort discards it. That required committing each turn's work onto the branch: without commits, deleting a branch discards nothing, so "abort discards the work" was a comforting phrase rather than a fact. The caller's own in-flight changes are committed to their branch first, so an abort cannot destroy work nobody delegated - Hard caps on turns and wall clock; a breach is a defined failure return, and its result is not usable, so the caller gates rather than resuming on a half-edited tree - Every event is checkpointed as it arrives, so a crash mid-delegation leaves the branch at a known commit and a truthful transcript - Handback is validated locally: blank fields or a non-boolean success flag are refused and the delegation continues rather than accepting a useless note Two failure modes found by running it against a real model: - A success claim with nothing changed was accepted. The handback plus file state is the entire interface back, so a note describing work that does not exist is worse than no note. Success now requires a successful mutating tool call; reporting failure still does not, since "this is impossible" is a legitimate finding - The delegate invented the absolute path /workspace, wrote there, ran its tests there, and handed back truthfully — with the repo empty and git seeing nothing. Writes outside the workspace are now refused with a message naming the real root, and both prompts state where the workspace is instead of leaving the model to guess. This is not sandboxing: work outside the repo is invisible to git, so the milestone would publish an empty PR Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> |

Add executor tool loop (A12/A15) — step 5b
- tools.py: four flat tools (read_file, write_file, list_dir, run_command) per A15's reduced manifest. Deliberately unsandboxed: the VM is the trust boundary (B3) and tool use is auto-approved inside an approved unit of work (A4), so path confinement would add failure modes without adding safety. What is enforced is operational — timeout with process-group kill so a backgrounded server cannot outlive its command, output truncation so a build log cannot eat the context window, closed stdin so prompts fail fast, and a scrubbed environment so project code never sees the agent's credentials - executor.py: renders the log, calls the executor role with the reduced manifest, dispatches tool calls, and checkpoints every result (A13). Escalation is observable, never self-assessed (A12): consecutive command failures and a hard turn cap. Failed reads do not count — looking around is not failing - Until delegation exists (step 7), escalation gates to the human with the failures attached - control.py: start milestone now runs the executor; a stopped milestone gates to AWAIT_INPUT Two bugs found by running it live against real models: - A turn-ending gate tool (submit_plan) left a tool_call with no tool_result, which providers reject outright, so every planning turn after the first failed with a 400. The planner now records the gate as the call's outcome, which is also the truthful transcript - The renderer now emits a placeholder for any tool_call lacking a result, so a crash between call and result (A3) cannot poison the transcript permanently Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> |
