A project is a tree of experiment nodes. The root (baseline) holds the starting code and a run command — the single shell command that trains or evaluates the node and prints its results to the run log. Every other node is a child branched off a parent, inheriting its code and its run command. The two rules this depends on — never edit a node a run has answered and the run command + env is a fixed contract — are the cardinal rules; everything below assumes them.

Before the first launch

Follow the session playbook's Python policy. Before launching, resolve the train/evaluation command and compute-specific requirements; ask only if the project setup leaves these or the chosen workflow unclear. Record the durable setup and execution recipe in the project's run command.

Provisional until it answers — repair, don't branch

Every node exists to establish a baseline or test a hypothesis. A run that dies on an error does neither — nothing was established, nothing was tested — so there is nothing to protect: fix that node's branch in place and re-run the same node. Successive runs on one node are how you get it working; a new node is for a new question.

Once a run does answer the node — it produced the result the node was after, good, bad, or nan — the node is frozen. Its branch is the code that result came from: never edit it again, branch a child instead. That holds however the run ended, and it is permanent — a disappointing number is a result, not a reason to repair.

Unintended behaviour is not an answer. An OOM, a timeout, a divergence from a bug, a missing dep — those are implementation and hardware details, and the node is still provisional (unless the node's hypothesis is about memory or runtime, in which case that outcome is exactly its result).

Repair cap: two runs in a row that answer nothing on one node, then ask the user. Different errors still count; a bare relaunch or a flavor/backend switch is a repair. If the same failure hits a second node, that is one setup problem — ask then. (Separate from the "~3 failed or regressed runs" scientific stop.)

Shape the tree — stacked bushes, not a flat fan or a noodle

The single most common way to drive a project badly is to get the shape wrong. There are two opposite failures, and the right shape sits between them:

FLAT FAN (wrong)            NOODLE (wrong)            STACKED BUSHES (right)
root                        root                      root
├ a ├ b ├ c ... ├ n         └ a                       └ lr-head        ┐ round 1:
                              └ b                        ├ lr 2e-5     │ a small fan of
                                └ c                      └ lr 3e-5     ┘ co-equal options
                                  └ d ...                   └ winner ── arch-head   ┐ round 2
                                                               ├ arch-A             │ descends onto
                                                               └ arch-B             ┘ round 1's winner

Flat fan (your whole sweep hanging off the root): every result is measured against the start, so wins never accumulate and the tree never makes progress.
Noodle (a long single-child chain): depth manufactured for its own sake — each step doesn't actually build on the one above it.
Stacked bushes (correct): a small fan within a round (the options of one decision), then descend onto that round's winner for the next round.

The one rule that produces this shape. Before you make X a child of Y, name what Y established that X builds on:

You can name it ("Y is the LR winner; X keeps that LR and changes the architecture") → real depth. X is a child of Y. Descend.
You can't — X and Y are co-equal options you're trying at the same time (lr 2e-5 vs lr 3e-5) → they don't build on each other. They're siblings in the same bush. Fan, don't chain.

So: width = the open options of one decision (fan freely — a 3-way LR sweep should be three siblings under a common head); depth = decisions already resolved, stacked (one level down per winner kept). A new round never hangs off the root — it hangs off the previous round's winner. That keeps the tree moving downward as research progresses, without stringing unrelated nodes into a line.

Re-read the tree each round — orx project view <projectId> lists every node (id, title, branch; roots marked [root]) — and check the shape: a wide row of direct children off the root with no grandchildren means you're fanning when you should be descending; a long depth-N chain with no branching means you're chaining co-equal variants that should have been siblings.

The auto-research loop

To drive a project toward a goal (e.g. "best convergence for d=8"), this is the intended flow — do not edit a frozen node or rewrite the run command:

Read the baseline's code. You already sit in a private Git worktree of the project's repository. Check out the branch and read it with your normal tools (see orx-git). See the node's run command with orx exp status <expId> and find where the knobs live (config files, hyperparameters, model definitions).
Form one round's worth of hypotheses — the co-equal options of a single decision (which LR? which schedule? which init?), each a concrete change you can make and measure against the others in this round. Don't mix decisions from different rounds into one batch — that's what produces the flat fan.
Create the round as a bush, and pick its parent deliberately. All of this round's options are siblings under one parent — the title is the idea, the description is the concrete change you'll make on that node's branch. The parent is:
- the baseline, only for the very first round (nothing has been won yet); or
- the previous round's confirmed winner, for every round after — so this round's changes build on top of the last gain instead of resetting to the start. This is what walks the tree downward (see "Shape the tree" above).
```
# Round 1 — one decision (the LR), its options fanned off the baseline:
orx create-experiment <projectId> --parent <baseId> --title "LR 2e-5" \
  --description "Set the LR in config.yaml to 2e-5; change nothing else."
orx create-experiment <projectId> --parent <baseId> --title "LR 3e-5" \
  --description "Set the LR in config.yaml to 3e-5; change nothing else."

# Round 2 — LR 3e-5 won → the next decision (architecture) descends onto it:
orx create-experiment <projectId> --parent <lr3e5WinnerId> --title "Wider MLP" \
  --description "On top of the LR-3e-5 winner, widen the MLP hidden dim 1024→2048 in model.py."
```
The child inherits its parent's run command automatically — you don't set it, and you never give siblings different commands or env vars (cardinal rule 2).
Implement each child's change on its Git branch — orx create-experiment prints the child's branch (orx/<slug>); in your worktree:
```
git checkout orx/<child-slug>
#   …edit only the files that idea touches…
git commit -am "cosine LR + warmup"
```
Leave the run command alone. Before launching, load orx-evidence and make sure the committed code emits enough run evidence to judge the node.
Launch the round's ready children: orx exp run <childId> --backend <b> (or omit --backend when a default target is set — see orx-compute). Remote backends can run siblings in parallel; --backend local shares this machine's CPU, RAM, and GPU.
Keep the round moving — drive a per-completion loop, not a wait-for-all barrier. You want control back the moment any one run finishes so you can analyze it and either refill its slot or stop — not after the whole batch drains. orx exp wait --project <projectId> is built for exactly this: it returns on the first completion. Treat it as one tick of a loop, where you are the loop body:
```
# after launching your runs, loop until the project is drained:
loop:
  orx exp wait --project <projectId>   # sleeps; returns on the first completion
  orx runs <projectId>                 # SOURCE OF TRUTH: re-read all run states
  # for each run now terminal that you haven't handled yet:
  #   - read its results (step 7) and decide: launch a refill? promote it? stop?
  #   - launch the next queued child to refill the freed slot (step 5)
  # if `exp wait` printed "drained: no runs in flight"  → batch is done, break
```
Three things make this robust — follow all of them:
- exp wait --project is a sleep-until-change signal, not the source of truth. It only reports completions it observed during that one call. A run that finishes while you're analyzing the previous one is already terminal by the next call and won't be reported. So on every wake, re-read orx runs <projectId> and reconcile against the set of runs you've already handled — act on every newly-terminal run, not just the line exp wait printed. (This is the one time you do look at orx runs in a loop — as the reconcile after each wake, not as a tight poll in place of exp wait.)
- Re-issue exp wait each tick. One completion → one return → you decide → you call it again. Don't expect a single exp wait to block until everything is done; that's the failure mode this loop avoids.
- Terminate on drained. When no runs are in flight, exp wait --project returns immediately printing drained: no runs in flight. That — or seeing every run terminal in orx runs with no more children to launch — is your exit condition. Don't keep calling it into a timeout.
Analyze each finish as it lands, then iterate. Do the per-completion read inside the loop above, not deferred to the end — when a run finishes, actually read its results with orx logs <runId> (see orx-evidence). To see exactly what a finished node changed, diff its branch against its parent's branch (see orx-git). Don't infer from status alone. Each completion is a decision point with four moves:
- Repair — the run answered nothing: fix this node's branch and re-launch the same node (above).
- Refill — result is mediocre or inconclusive: launch the next queued child to keep the round moving (step 5).
- Promote — result is a clear win: this node becomes the parent for the next round. The next batch of children branch off it, not the baseline, so the win carries forward and the next ideas stack on top of it. This is the move that makes the tree grow deeper; skipping it is what produces a flat, sweep-only tree.
- Stop — goal met, or the branch is exhausted.
Frozen nodes stay untouched throughout — promotion moves the focal parent down the tree, it never rewrites a node that already measured something.

Stop when the goal is met, or after ~3 consecutive failed or regressed runs. When you stop, write up the tree as a descriptively named project artifact — see the orx-reports skill for naming and folder guidance.

Close any turn that ran or changed experiments with a short experiment summary: one line per relevant node with what it tested, its status, and the headline result. Follow the session playbook's evidence-and-links contract. Plain questions and turns that launch or change no experiments need no summar

A project is a **tree of experiment nodes**. The root (**baseline**) holds the

**child** branched off a parent, inheriting its code and its run command. The two

**the run command + env is a fixed contract** — are the cardinal rules;
everything below assumes them.

## Before the first launch

## Shape the tree — stacked bushes, not a flat fan or a noodle

The single most common way to drive a project badly is to get the **shape** wrong.
There are two opposite failures, and the right shape sits between them:

```
FLAT FAN (wrong) NOODLE (wrong) STACKED BUSHES (right)
root root root
├ a ├ b ├ c ... ├ n └ a └ lr-head ┐ round 1:
└ b ├ lr 2e-5 │ a small fan of
└ c └ lr 3e-5 ┘ co-equal options
└ d ... └ winner ── arch-head ┐ round 2
├ arch-A │ descends onto
└ arch-B ┘ round 1's winner
```

- **Flat fan** (your whole sweep hanging off the root): every result is measured
against the *start*, so wins never accumulate and the tree never makes progress.
- **Noodle** (a long single-child chain): depth manufactured for its own sake —
each step doesn't actually build on the one above it.
- **Stacked bushes** (correct): a *small fan within a round* (the options of one
decision), then **descend onto that round's winner** for the next round.

**The one rule that produces this shape.** Before you make X a child of Y, name
what Y established that X builds on:

- **You can name it** ("Y is the LR winner; X keeps that LR and changes the
architecture") → real depth. X is a **child** of Y. Descend.
- **You can't — X and Y are co-equal options you're trying at the same time**
(lr 2e-5 vs lr 3e-5) → they don't build on each other. They're **siblings** in
the same bush. Fan, don't chain.

So: **width = the open options of one decision** (fan freely — a 3-way LR sweep
*should* be three siblings under a common head); **depth = decisions already
resolved, stacked** (one level down per winner kept). A new *round* never hangs off
the root — it hangs off the previous round's winner. That keeps the tree moving
**downward** as research progresses, without stringing unrelated nodes into a line.

Re-read the tree each round — `orx project view <projectId>` lists every node
(id, title, branch; roots marked `[root]`) — and check the shape: a wide row of
direct children off the root with no grandchildren means you're fanning when you
should be descending; a long depth-N chain with no branching means you're chaining
co-equal variants that should have been siblings.

## The auto-research loop

To drive a project toward a goal (e.g. "best convergence for d=8"), this is the
intended flow — do **not** edit a frozen node or rewrite the run command:

1. **Read the baseline's code.** You already sit in a private Git worktree of the
project's repository. Check out the branch and read it with your normal tools
(see `orx-git`). See the node's run command with `orx exp status <expId>` and
find where the knobs live (config files, hyperparameters, model definitions).
2. **Form one round's worth of hypotheses** — the co-equal options of a *single*
decision (which LR? which schedule? which init?), each a concrete change you can
make and measure against the others in this round. Don't mix decisions from
different rounds into one batch — that's what produces the flat fan.
3. **Create the round as a bush, and pick its parent deliberately.** All of this
round's options are **siblings under one parent** — the title is the idea, the
description is the concrete change you'll make on that node's branch. The parent is:
- the **baseline**, only for the very first round (nothing has been won yet); or
- the **previous round's confirmed winner**, for every round after — so this
round's changes build *on top of* the last gain instead of resetting to the
start. This is what walks the tree downward (see "Shape the tree" above).

```sh
# Round 1 — one decision (the LR), its options fanned off the baseline:
orx create-experiment <projectId> --parent <baseId> --title "LR 2e-5" \
--description "Set the LR in config.yaml to 2e-5; change nothing else."
orx create-experiment <projectId> --parent <baseId> --title "LR 3e-5" \
--description "Set the LR in config.yaml to 3e-5; change nothing else."

# Round 2 — LR 3e-5 won → the next decision (architecture) descends onto it:
orx create-experiment <projectId> --parent <lr3e5WinnerId> --title "Wider MLP" \
--description "On top of the LR-3e-5 winner, widen the MLP hidden dim 1024→2048 in model.py."
```
The child inherits its parent's run command automatically — you don't set it,
and you never give siblings different commands or env vars (cardinal rule 2).
4. **Implement each child's change on its Git branch** — `orx create-experiment`
prints the child's branch (`orx/<slug>`); in your worktree:
```sh
git checkout orx/<child-slug>
# …edit only the files that idea touches…
git commit -am "cosine LR + warmup"
```
**Leave the run command alone.** Before launching, load `orx-evidence` and
make sure the committed code emits enough run evidence to judge the node.
5. **Launch the round's ready children**: `orx exp run <childId> --backend <b>`
(or omit `--backend` when a default target is set — see `orx-compute`). Remote
backends can run siblings in parallel; `--backend local` shares this machine's
CPU, RAM, and GPU.
6. **Keep the round moving — drive a per-completion loop, not a wait-for-all
barrier.** You want control back the moment *any one* run finishes so you can
analyze it and either refill its slot or stop — not after the whole batch
drains. `orx exp wait --project <projectId>` is built for exactly this: it
returns on the **first** completion. Treat it as one **tick** of a loop, where
*you* are the loop body:

```
# after launching your runs, loop until the project is drained:
loop:
orx exp wait --project <projectId> # sleeps; returns on the first completion
orx runs <projectId> # SOURCE OF TRUTH: re-read all run states
# for each run now terminal that you haven't handled yet:
# - read its results (step 7) and decide: launch a refill? promote it? stop?
# - launch the next queued child to refill the freed slot (step 5)
# if `exp wait` printed "drained: no runs in flight" → batch is done, break
```

Three things make this robust — follow all of them:
- **`exp wait --project` is a sleep-until-change signal, not the source of
truth.** It only reports completions it observed *during that one call*. A
run that finishes while you're analyzing the previous one is already terminal

- **Stop** — goal met, or the branch is exhausted.

Frozen nodes stay untouched throughout — promotion moves the *focal parent*
down the tree, it never rewrites a node that already measured something.

Stop when the goal is met, or after ~3 consecutive failed or regressed runs.
