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

The second renderer adapter, and the concrete case for A13's decision
to normalise in the renderer rather than on the wire. The two vendors
disagree structurally, not cosmetically: the system prompt is a
top-level field rather than a message, a tool call is a tool_use
content block rather than an array, a tool result is a block inside a
user message rather than a "tool" role, and tool schemas use
input_schema rather than parameters. A middlebox flattening those
would be lossy exactly where a long-running delegation lives.
- render_anthropic.py builds vendor-native /v1/messages bodies from
the canonical log, coalescing adjacent same-role blocks so a
tool_result lands directly after its tool_use
- Tool manifests are declared once in OpenAI shape and converted per
vendor, so adding a tool does not mean editing two places
- AnthropicPassthroughClient implements the same LLMClient protocol,
so callers pick a route rather than a different kind of client, and
maps provider tool ids to canonical ones at the boundary
- Dangling tool calls get a placeholder result here too; this API
rejects them more strictly than the OpenAI shape
- Vendor-opaque reasoning blocks are dropped for now with the reason
recorded: A10 wants them stored and never replayed across sessions,
and the canonical schema has no event for that yet
Live tests prove the body is accepted as sent, that a tool_result
turn round-trips, and — as A5 asks — that prompt cache accounting
survives the passthrough rather than being flattened by the proxy.

- approvals.py: PlanBoard opens one issue per project and posts each
plan revision as a comment carrying its rev tag. The state store
keeps only a pointer, so gate state can be re-derived from Gitea
after a state-volume loss — external truth wins
- Gitea comments are a second approval source: revision binding, the
typed word approve, and first-approval-wins work exactly as over
transport, with a per-channel allowlist because a Gitea login is
not a Matrix MXID
- Outcomes are echoed to the other channel, so the two records cannot
silently disagree about what was approved
- A Gitea outage degrades durability of the record, not the ability
to approve: planning proceeds and Matrix remains a complete channel
- Live test now asserts the server refuses the agent's own merge and
its push to the protected branch. That property was previously
true only because our code did not attempt it; branch protection
makes it structural, and this test fails if the protection is ever
relaxed
- Fixed a race in the process-group test: killing a group is
asynchronous and the grandchild is an orphan, so its exit is not
synchronised with our return; the test now waits for death

The standalone half of the Gitea layer; orchestrator wiring follows
once the executor loop lands, to avoid colliding with it in
control.py.
- gitea.py: GiteaClient over httpx — open PRs, list and post issue
comments, close PRs. find_pull_request is the A3 external-truth
query that makes opening a PR idempotent across a crash, and it
checks closed PRs too, since a crash after opening must not be
answered with "nothing is open, so open another"
- pull_request_reconciler: an unreachable Gitea returns None rather
than a guess, so the agent gates to the human instead of risking a
duplicate side effect
- git.py: branch, commit, push for the workspace. The token is passed
per-invocation rather than stored as a remote, so it never lands in
.git/config, and anything raised is scrubbed of it
- commit_all returns None when there is nothing to commit: an empty
milestone is a fact to report, not an error
- Live test does the real round trip against the sandbox repo and
cleans up after itself

Two invariants only a live homeserver can check, now enforced rather
than verified by hand:
- The configured NISSE_MATRIX_USER_ID must be the token's real owner.
MatrixTransport filters its own messages by comparing sender to that
value, so a mismatch would make the bot read its own posts as
operator input.
- The account must be a testing identity, so a stray live run can
never act as the production agent.
Both hold today; this keeps them holding when the production
nisse-dev account is created.

Found while chasing a flaky live test, but the flakiness was a real
bug: only the ask_human path recorded a pending item, so AWAIT_INPUT
reached any other way — planning failure, stopped milestone, boot
reconciliation — refused every operator reply with "no pending
question to answer" and the agent could never be recovered. The
operator had no way back short of wiping state.
Every path into AWAIT_INPUT now records what a reply should resume,
and answering dispatches on it: planning failures and questions
resume planning, a stopped milestone returns to its still-approved
gate, and the fallback says what commands work instead of
dead-ending. Two regression tests cover the recovery paths.
The live test also scripted a fixed approve/approve/start sequence,
which a real model breaks by legitimately calling ask_human at a
gate. It now plays the operator adaptively, responding to whatever
the agent actually did. Five consecutive live runs pass.

- 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

- planner.py: LLMPlanningAgent offers exactly two tools, submit_plan
and ask_human, so gating stays structural at the tool layer; no
proceed tool exists. System prompt requires explicit, low-inference
plans because a weaker model executes them (A13)
- Model output is appended to the canonical log as it arrives, before
being interpreted, so a crash mid-planning leaves a truthful
transcript
- A bad turn (prose instead of a tool call, malformed arguments, or a
failed call) retries once, then raises PlanningError; the
orchestrator gates to AWAIT_INPUT rather than inventing a plan
- Orchestrator: appends every operator message, plan_submitted, and
gate_opened to the transcript, so re-planning sees rejection
feedback as conversation rather than out-of-band parameters; pins
the A11 role mapping at task start
- llm.py: non-JSON or non-object tool arguments now raise LLMError
instead of escaping as JSONDecodeError — observed from llama3.2,
which emits truncated argument strings
- Live planning test is opt-in on NISSE_LIVE_PLANNER_MODEL: planning
escalates unconditionally (A12) and the local model does not hold
the tool-call contract, so it awaits a frontier route

Skipping now keys solely on NISSE_LLM_BASE_URL and
NISSE_MATRIX_HOMESERVER: if the sentinel is set, the live path is
expected to work and any other missing variable is an assertion
failure naming it, not a silent skip. A misnamed or misplaced CI
secret previously produced a green run with no live coverage.

- matrix.py: Transport implementation over the Matrix client-server
HTTP API directly (token auth, /sync long-poll, /send) using the
existing httpx dependency — no Matrix SDK; four endpoints total.
Deviation from the presented plan (matrix-nio) flagged in the PR
- First sync learns position and skips backlog, so room history is
never delivered as context (A1); own messages and non-message
events filtered; sender MXID passed through for the orchestrator's
operator allowlist
- Sync loop backs off (capped at 60s) and retries indefinitely on
homeserver errors, mirroring B2's polling posture
- Encrypted rooms unsupported: bot rooms are created unencrypted
until E2E lands (operator decision; room recreated accordingly)
- NISSE_MATRIX_TEST_ROOM_ID added: the live smoke test binds only
to the dedicated test room, never the production room
- 8 unit tests over a mocked HTTP layer; live integration test
verified against the real homeserver

PR 2 of the steps-3/4 plan.
- llm.py: LLMClient protocol — complete(events, tools, model) ->
canonical events — present from the first real LLM call.
LiteLLMClient renders requests via the A10 renderer, targets the
proxy's OpenAI-compatible route, and maps provider tool-call IDs
to locally-minted canonical IDs at the boundary
- RoleMap (A11): executor/planner/delegate/consultant resolved from
env; pinned() returns the mapping to record at task start
- Config strictly from env: NISSE_LLM_BASE_URL, NISSE_LLM_TOKEN;
envfile.py is a minimal .env loader where real env wins; .env now
gitignored with a committed .env.example documenting all variables
(Matrix ones included for the upcoming transport PR)
- Live smoke test against the proxy is integration-marked and skips
without credentials — CI stays credential-free per operator
decision; the test runs locally once .env exists
- httpx added as nisse-dev's HTTP client

Build-order step 4, sequenced before the LLM client (step 3) because
the client interface consumes the canonical log.
- canonical.py: typed events for the full A10 table (user_message
through compaction); canonical tool-call IDs minted locally,
provider IDs never a join key; strict payload validation on load
- StateStore: canonical_events table via schema v2 — the first real
migration, exercised in a test against a hand-built v1 database —
with append_event/read_events on the same fsync-per-commit path
- render.py: request bodies rendered from the log at call time;
first adapter targets the OpenAI-compatible shape of LiteLLM's
normalized route; compaction events replace their id range at
render time while staying in the durable log
- Crash integration test now also verifies transcript appends
survive process death

Step-2 PR A: the approval loop end to end with a stub agent, no LLM
and no network.
- transport.py: Transport interface per A1 (send_message,
send_approval_request, ask_question, on_message) with an
InMemoryTransport; no platform SDK outside an implementation
- gates.py: PlanRevision with monotonic rev-N tags; Gate.evaluate
enforces revision binding (stale tags refused with a notice),
operator allowlisting, and approve-word-only semantics; any other
reply is rejection feedback. Channel seam ready for Gitea/Vikunja
approval sources
- control.py: B1 state machine subset with structural gating — the
agent's only actions are SubmitPlan (ends its turn) and AskHuman;
no proceed tool exists. Gate state, revision counters, task_id,
and pending questions checkpoint through StateStore, and boot
resumes an open gate or gates to AWAIT_INPUT, never blind-resumes
- gate.open/approve/reject A9 events complete the log taxonomy
- CLAUDE.md: record the plan-first working convention
- Tests: 15 unit (gates + orchestrator flows), 2 integration
(mid-gate restart with revisions intact; unresolved intents gate
the whole boot)

Retrofit for the conventions merged in #4 (issue #3):
- OpLog: JSON-lines emitter with the fixed envelope (ts, agent,
event, task_id, cause); task_id set by the orchestrator at
unit-of-work start
- StateStore owns emission: transition, intent begin/commit/abort,
and schema migrations each emit their event right after the
durable write commits; callers pass the cause
- reconcile_on_boot emits boot.reconcile with action and verdicts,
and resolves intents with reconciliation-verdict causes
- Failed resolutions emit nothing (a line exists iff the write
committed)

Build-order step 1: the critical path everything else sits on.
- StateStore: SQLite in WAL mode with synchronous=FULL, so every
state transition and intent-log write is committed and fsynced
before returning; a power cut cannot tear state
- Durable intent log: begin_intent records a unit of work before it
starts; commit/abort resolve it; pending intents survive restart
- schema_version stamped from the first commit, with a sequential
migration hook; a newer state file than the code supports is
refused rather than misread
- reconcile_on_boot (A3 first cut): pending intents are checked
against external truth by registered reconcilers (observable
checks, never model self-assessment); verified effects are
committed, verified no-ops aborted, anything unverifiable gates
to AWAIT_INPUT — never blind-resume
- Lives in nisse_dev per spec 0.1: the library is extracted after
the dev agent works, not designed up front
- Integration test kills a subprocess mid-work with os._exit and
verifies state integrity and intent visibility on reopen

- uv workspace tying nisse-core, nisse-dev, nisse-ops together
(src layouts, workspace-sourced nisse-core dependency)
- Placeholder hello-world entry points for both agents, calling
through nisse-core to exercise the package boundary
- pytest unit tests per package; integration tests (marker-gated)
running the installed console scripts as subprocesses
- ruff lint + format, nisse_* declared first-party
- Gitea Actions workflow running lint, format check, unit and
integration tests; scripts/check.sh mirrors it locally
