Strategy-agent end-to-end audit (post-PR-A1..A12) caught a critical bug
that hadn't fired yet because no agent deploy has succeeded since the
agent was built (24 trades < 50-trade safety floor, so all weekly runs
have been "no-deploy diagnostic"). The first time it tries to deploy:
agent_writes.deploy_change does:
1. git checkout -b agent/change-<timestamp>
2. git add <files> && git commit
3. git checkout main
4. git merge agent/change-<timestamp> --no-ff ← LOCAL only
5. git branch -d agent/change-<timestamp>
Step 4's merge commit lives only on the runner's local checkout of
main. There is NO `git push`. When the runner shuts down, the merge
commit is discarded.
Meanwhile the workflow's "Open PR for agent code changes" step
(added in PR #160) does:
git add <agent-modifiable-files>
git diff --cached --quiet → exit deployed=false if no staged diff
Because the agent already committed and merged locally, there are no
staged changes. The workflow exits deployed=false. No PR is opened.
No notification fires. The agent's changelog records status=deployed
with a commit_sha that points at the discarded local merge commit.
Net effect: ghost deploy. Changelog says deployed; live code is
unchanged. compute_measured_impact 5 days later compares equal-state
windows, reports no effect. The agent may re-attempt the same change
on the next eligible cycle (after 14d cooling), perpetually
ghost-deploying.
Fix: deploy_change does the push and opens the PR itself.
- After commit on the feature branch, `git push origin <branch>
--force-with-lease`.
- `gh pr create` to open the PR; on failure (re-run same day; PR
already exists), recover URL via `gh pr view`.
- Persist PR URL to data/agent/last_pr_url.txt for the workflow's
Telegram step to pick up.
- DO NOT merge to local main. main is protected — the PR is the
deploy gate, CI runs on it, merging requires the operator (or an
auto-merge rule).
Workflow change: the "Open PR for agent code changes" step is renamed
to "Surface agent deploy PR" and rewritten to read the PR URL the
agent persisted. It no longer does its own push or pr-create — that
responsibility now lives entirely in agent_writes.deploy_change. The
"Run Strategy Agent" step gets GH_TOKEN env so the agent's gh CLI
calls authenticate.
Tests: 3 new in TestDeployChange covering the new push+PR path —
successful PR creation, gh pr create fails (PR already exists)
recovery via gh pr view, git push failure aborts cleanly.
The obsolete test_merge_failure was removed (no merge step anymore).
Verified locally: 2820 tests pass (was 2818; net +2).

Reviewer caught a critical data-flow bug in the workflow: the agent's `data/agent/last_pr_url.txt` was being wiped by the immediately-prior "Commit agent state to trading-data branch" step. That step does a git checkout main → trading-data → main round-trip; the closing `git checkout main` removes anything under data/agent/ from the working tree (data/ is gitignored on main; tracked on trading-data). So the surface step would always find the file missing and exit deployed=false. Net effect: deploy reaches origin (the actual ghost- deploy fix works), but the Telegram surface notification is silently dropped. Fix: write the URL to $RUNNER_TEMP/agent-pr-url.txt instead of data/agent/. RUNNER_TEMP is per-run on GHA so there's no cross-run staleness; falls back to /tmp locally. The workflow's surface step reads from $RUNNER_TEMP first. Also added a WARNING log when both `gh pr create` and `gh pr view` return failure (pr_url ends up empty string) — branch is pushed but the surface notification will be skipped, so post-mortems can find it. Test renamed test_deploy_writes_pr_url_file_for_workflow -> test_deploy_writes_pr_url_file_to_runner_temp and updated to set RUNNER_TEMP via monkeypatch + assert the file is NOT under data/.

bandit's B108 hardcoded_tmp_directory flags `/tmp` literals. tempfile.gettempdir() returns the platform tempdir (still /tmp on Linux, but discovered properly), avoiding the static-string surface that bandit's heuristic catches. The actual prod path on GHA is $RUNNER_TEMP — only the local-dev fallback changed. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

mainrequires 4 status checks (test,lint,type-check,secrets-scan). PR #160 deliberately switched the agent from direct push to PR-based deploys for exactly this reason — bypassing CI to auto-merge would re-introduce the "agent commits unreviewed code to main without CI" risk. Agent's job ends at PR opened; operator (or a future auto-merge rule) reviews and merges.Verified
