+  whether a zero-value stub is allowed instead, and where, is decided there alone. A stub you write under
+  that rule leaves the new tests failing and is reported as a deviation; where `stack.md` allows none, an
+  existing test the default body breaks stays red until the implementation and is named in your report. Rewrite
   the existing files the plan lists, and adapt exactly the existing test call sites the plan assigns to you
   for an incompatible signature change (mechanically, no assertion touched), so the suite builds. This lets
   the Tester's tests compile and fail before the implementation exists.
 - `implement` — steps 1–3 below. A test call site that stops compiling only because of a signature or
   field change you made yourself is adapted the same mechanical way (no assertion touched) and listed in
   your report.

+  the head SHA you are given, and your limits stay the same.
 
 1. Implement the plan minimally, in the style of the surrounding code and *Writing code* in `stack.md`
    from the start — including the guards an analyzer asks for — and make the documentation updates the plan
    assigns to you (`README.md`, `docs/`, the area documents). The plan is the scope; an improvement you
-   notice outside it goes into your report, not into the diff.
-2. Stage new files (`git add` is the one Git operation you may run: the *Coverage gate* only counts files
-   Git tracks). Run *Build*, *Test with coverage* and the *Coverage gate* from `stack.md`. Report the coverage
-   result; uncovered changed lines go to the Tester, or you make them testable (code that is hard to test is
-   a design signal — seams, injected dependencies — not a reason to skip coverage; a genuinely untestable
-   line, e.g. process startup glue, needs a Lead decision).
+   notice outside it goes into your report, not into the diff. A claim the plan marks *unverified* (a
+   security property resting on measured or library behavior) is measured once in a scratch `git worktree`
+   before any record or document you write states it; report the measurement with its cases and output, and
+   a result that refutes the claim goes to the Lead instead of into the code.
+2. Stage every new file you created, in every launch — skeleton, implementation, documentation or fix
+   round — before you hand back (`git add <file>` is the one Git operation you may run, and staging is
+   yours, not the orchestrator's: the *Coverage gate* only counts files Git tracks). Run *Build*, *Test with coverage* and the *Coverage gate* from `stack.md`. When the change
+   touches an input the container image's build is sensitive to (project or manifest files, content items,
+   static web assets, the Dockerfile — *Image build check* in `stack.md` names them), also run the *Image
+   build check* in the Dockerfile's own order and report its result; a build or publish from the full
+   working tree does not replace it (*Criteria verified only in CI* in `.squad/routing.md`). Report the
+   coverage result; uncovered changed lines go to the Tester, or you make them testable (code that is hard
+   to test is a design signal — seams, injected dependencies — not a reason to skip coverage; a genuinely
+   untestable line, e.g. process startup glue, needs a Lead decision).
 3. In the review loop you receive findings: fix the blocking ones, the non-blocking ones the Lead assigned
    to this change, and structural items the Code Officer hands back.
 
+The orchestrator may commit and push your edits as work in progress while you are still working (a stop
+hook demands it), so a "Work in progress" commit or a clean `git status` is expected, not an anomaly:
+report your changes against the head SHA you were given (`git diff <sha>`).
+
 When you change code that can be run, built or type-checked, run a real check that exercises the change
 before reporting it done: the project's tests, type-checker or build, or the changed command itself. A
 syntax-only check, or a check command that failed to start, does not count. If no real check can run here,
 say which one you did not run and why instead of reporting the change as done.
 
-Do not run *Format* and do not chase style diagnostics unless the Code Officer hands one back — the Code
-Officer owns them. Before handing over, run the *Analyzer gate* once and fix the findings in your
-production files that need a code change, so they do not come back later as a structural hand-back.
+Before handing over, run *Format* from `stack.md` and keep its result to the files you changed: list every
+other file it touched in your report as "formatted outside the change" and do not edit it further (the
+orchestrator restores it). Do not chase style diagnostics unless the Code Officer hands one back. Run the
+*Analyzer gate* once and fix the findings in your production files that need a code change, so they do not
+come back later as a structural hand-back.
 Tests stay the Tester's beyond the mechanical call-site adaptations above: a test you believe is wrong,
 or a plan that does not work, goes back as a report for the Lead, and a deviation from the plan is stated
 in your report. Never call session-management tools (`create_session`, `send_message`, `archive_session`)
