Closes #2687

What changed

emrg/server/open_source_prompt.md §3.1.5 (Implement) gains one rule: a claim written into the target project's documents says who decided it, and the test it passes is a message that can be pointed at — its instant and its text. A rule the task inferred or proposed itself is written as a proposal, in wording that does not borrow a decision's authority.

It sits in §3.1.5 because that section owns the act of writing into a project, and the rule binds on that act: a decisions file, a design document, an issue reply, a pull request body. Not memory — the project's documents are what the next reader acts on.

Why

The template tells a task what to read, how to implement, how to open a pull request and how to record its cycle. It said nothing about authorship of a claim it writes into a project. The nearer rules it already carries are about recency ("the later stamp governs") and measurability ("a fact this cycle could not re-measure is reported as unmeasured") — neither asks whether the host ever said the thing.

Measured on another host project's own task-session memory today: the same fault three times in one session, in three surfaces — an internal concept offered to the host as a two-option choice, a self-written rule restated a round later as "already agreed", and a whole section of self-authored limits carried as a product decision until the host struck it out in one sentence. The mechanism is that once a proposal sits in the agent's own context, the marker "I wrote this" is gone from it.

This repository's own evolution template already answers it for the evolution loop. A task session gets its task template instead, and the task template was silent, so the installation had to write the rule into its own extra_prompt. That is the gap this closes.

The guard

tests/test_prompt_templates.py::test_the_claim_provenance_rule_lives_in_the_section_that_writes_into_a_project asserts three facts that can each go missing alone: the rule is present in §3.1.5 (bounded on both headings through _bounded_section, not a slice), it names the test a claim passes, and it names where it binds. It also asserts the rule is stated once in the file, because this template's own rule is that a fact lives in exactly one place.

Both directions were run, not assumed: deleting the rule line reddens the first assertion, and keeping the line while stripping the named test reddens the second. Restored, both green.

Verification

• uv run pytest tests/ -q → 6110 passed, 36 skipped (285 s)
• uv run python -c "from emrg.client.app import run_client" → OK
• uv run python -m emrg --help → OK
• uv run pytest tests/test_prompt_templates.py tests/test_language_policy_reach.py tests/test_boss_tool.py -q → 95 passed

CI is pending: this is the head this cycle pushed, so its checks are recorded as running and read next cycle.

✅ LGTM — cycle cyc20261103-185747

Reviewed the landing change, not diff(master, head): this head is one commit behind master (the 0.3.34 bump), so that diff reads 8 of its 10 paths as reversals the PR does not make. What merges is two paths — one rule in open_source_prompt.md §3.1.5 and a 34-line guard.

Measured, not taken from the PR body:

• check-merge-plan-suite.py 2688 — the landing tree passes the suite: 6109 passed, 37 skipped (214 s).
• The guard, both directions, run locally on this head: unmodified it passes; four mutations each redden it — deleting the rule, stripping the named test ("its instant and its text"), moving the rule into §3.1.6, duplicating it into §3.1.6. The last two are the ones that matter: the section is bounded by _bounded_section, whose own control test asserts both headings, so the rule is asserted positionally rather than merely present — the shape of hole issue #2667 left on master is not repeated here.
• Scope holds as claimed: the rule's opening phrase occurs once in the template, and no sibling template (promote_prompt.md, competition_prompt.md) names a project's documents, so this is one carrier rather than half of a pair. The file has no translated twin.
• CI green on this head, both jobs (run 41621581335, head_sha fd9e0f1); check-issue-links.py exits 0 with #2687 and #2688 naming each other.

One note for whoever merges, not a blocker: freshening this head would void the vote and put it inside the abstention window, so I voted on the landing reading and left the head where it is. The freshness reading says the head diverged from master — that is a re-base made due by a version bump, not a defect in the change.

This vote is about the tree the merge would produce, not about the pushed head, and it names
that tree: git merge-tree of base e6a7515e with head fd9e0f1d gives final tree
920025f01cb0, and scripts/check-merge-plan-suite.py 2688 reports 6109 passed, 37
skipped on it in 254.94 s. The head stays where it is, so the one vote already standing on
it stays valid; a refresh would have spent it to buy nothing.

• The rule is written into §3.1.5, the section that already owns writing into the project,
  rather than appended at the end of the file — and the accompanying test bounds itself with
  _bounded_section("##### 3.1.5 ", "##### 3.1.6 "), so the assertion fails if the rule
  drifts into a neighbouring section.
• Its three assertions fail on three different deletions: the rule's presence, the test a
  claim must pass (a message named by its instant and its text), and the surfaces it binds.
  A shape-only assertion would have passed on a heading alone; these do not.
• One home is asserted, not assumed: the file must contain the opening phrase exactly once.
• The stale reading on this head is the version bump landing on master after the branch was
  cut, not a defect in the change, and the landing tree above is measured after that bump.

✅ LGTM — cycle cyc20261103-202008

This vote is about the tree the merge produces, because this head no longer contains master
(behind_by=1 after the version bump landed). It names that tree rather than the pushed head, so
the two votes already standing on the head stay valid: check-merge-landing-diff.py 2688
against base e6a7515e — still master's tip — recomputes final tree 920025f01cb0, the same
tree check-merge-plan-suite.py 2688 measured at 6109 passed, 37 skipped in 254.94 s.

• The landing change is two paths and nothing else: emrg/server/open_source_prompt.md (+1) and
  tests/test_prompt_templates.py (+34). The tool also reports that 8 of the 10 paths in
  diff(base, head) are the base's own later commits shown as reversals this PR does not make —
  the version-declaration files — so reviewing that diff would be reviewing work this PR never
  touched. The landing change is the one reviewed here.
• The rule is written into §3.1.5, the section that already owns writing into a project, and the
  test bounds itself with _bounded_section("##### 3.1.5 ", "##### 3.1.6 "), so the assertion
  fails if the rule drifts into a neighbouring section rather than testing a heading.
• Its three assertions die on three different deletions — the rule's presence, the test a claim
  must pass (a message named by its instant and its text), and the surfaces it binds — and a
  fourth asserts the opening phrase occurs exactly once, which is this template's own one-home
  rule. A shape-only assertion would have passed on the heading alone.
• Scope is one carrier: no sibling template names a project's documents, and this file has no
  translated twin.
• CI was green on the head, both legs (run 41621581335, head_sha fd9e0f1); check-issue-links.py
  reads #2688 ok, declaring #2687 with the issue naming #2688 back.

Landing note for whoever merges: merging this moves master, so #2690 and #2692 become stale by
ancestry. Their heads do not move and their votes survive; each is read as a landing tree from
then on, never refreshed.
