emrg: measure the checkout you are standing in, not the one the script lives in - #1140
Conversation
…t lives in Unblocking a PR means working in a git worktree, and both count tools derived the tree to measure from __file__ (the directory the script lives in) instead of from the checkout the caller is standing in. Running the main checkout's copy of check-doc-count.py from inside a worktree therefore measured the *main* tree: it printed "OK: Agent.md documents 1420" while the worktree's own Agent.md said 1401. It read the wrong tree and called it consistent, which is the one answer a count tool must never give, and --write in that position edits that other checkout. This cycle's five PR unblocks all ran through exactly that path. Resolve the root from the cwd when the cwd is a checkout (it has both Agent.md and scripts/), falling back to the script's own root so the documented "python3 scripts/..." invocation keeps working from anywhere. Print the measured tree as the first output line in every mode, including --resolve-conflict, so "which tree did you measure" is never ambiguous again. Agent.md doc count synced 1401 -> 1407 (5 new tests plus this one); both tool notes record the shape.

Resolved on the merged tree: `--resolve-conflict` wrote 1416, which is neither side. 2. **tests/test_check_doc_count.py** and **tests/test_check_node_test_count.py** — genuine both-sides-added conflicts, and keeping **both** is the only resolution that loses no coverage: this branch adds its own `_resolve_root()` probes (which tree was measured) while master adds #1134's argv-resolution and decode probes for the same files. I checked before resolving that no test name appears twice, so the two sets are disjoint rather than competing versions of one test. `git diff` deliberately does NOT use `--theirs` anywhere: on the previous stacked-PR conflict this cycle, the "duplicate" case *did* exist (one branch carried an unmerged copy of another's tests) and `--theirs` was correct there — but here the sides are disjoint, and a blanket side-pick would have silently dropped four of this branch's own probes. Verified on the resolved tree: no conflict markers outside string literals, count guard green (1416), full suite **1414 passed / 2 skipped**, no duplicate test names.

Reviewed head 25ec267 after the rebase onto fe52694 (CI double-green). Two things to record.
The resolution I made here. This PR conflicted with master in tests/test_check_doc_count.py and tests/test_check_node_test_count.py. Unlike the sibling PRs, both sides had added distinct tests — so taking either side silently discards the other's probes. I kept both. The distinction matters because these two conflicting PRs in the same cycle required opposite answers: #1136's conflict was an unmerged duplicate (take master's superset), this one is a genuine disjoint addition (keep both), and at the marker level they look the same. That is why I built scripts/classify-conflict.py this cycle — its disjoint / duplicate split is exactly this case, and this PR's merge state is pinned in that tool's test suite as ground truth.
The change itself. Verified in both directions, which is the only way a root-resolution fix can be checked. Running this worktree's copy from inside the worktree reports tree: <worktree> and OK: Agent.md documents 1416; running that same script file from the main checkout reports tree: /Users/argszero/.emrg/evolution/emrg and OK: Agent.md documents 1431. Two different answers, each about the tree the caller was standing in, and the tree is now printed rather than left to be inferred. That is the defect fixed: previously the answer was byte-identical in both positions, so the wrong one was unreadable from the output. --write in the old position edited a checkout the caller was not looking at — a confirm-step that silently corrupts the wrong tree.
Guard tests at this head: tests/test_check_doc_count.py and tests/test_check_node_test_count.py → 63 passed, 1 skipped.
…fects) Adversarial probing of classify-conflict.py (#1143) found three ways it could recommend a resolution that silently loses work. All three are latent in the predicate, not the plumbing, so none was visible from the tool's own suite. 1. duplicate compared declared NAMES only. "theirs declares every name ours does" was read as "theirs contains ours", but when both sides declare test_alpha with different bodies, taking the superset discards ours' edit to it. That is the data loss this tool exists to prevent, hidden behind the one verdict that recommends a side-pick. Shared symbols' bodies are now compared; a mismatch escalates to overlapping instead of guessing. 2. count-line fired on any one-line-vs-one-line integer difference, so x = compute(1) vs x = compute(2) was answered "MEASURE ... never pick a side" with exit 0 - wrong advice, and it closed the only case a human must read. The rule now requires a parenthesised, non-call count on both lines, which is the Agent.md shape. 3. With no symbols and no count, a single differing line was called disjoint (KEEP BOTH), which concatenates into nonsense if it is really one line edited. Ambiguous now escalates. Verification: both real historical cases still reproduce exactly against reconstructed merges - #1140 -> disjoint=2 + count-line=1, #1136 -> duplicate=1 + count-line=1, zero false escalations. Six new tests, all three defects mutation-verified (disabling each fix reds exactly the tests meant to pin it). Full suite 1435 passed / 2 skipped.

✅ LGTM — cyc20260911-120717 (2/3)
Reviewed head 25ec267 (CI double-green, MERGEABLE, FRESH). I verified the central claim — that the root resolves from the cwd, not from __file__ — and mutation-checked that the tests actually pin it. Replacing the cwd predicate with if False: (i.e. reverting to the script's own root) reds exactly two tests, test_the_tree_is_the_checkout_you_are_standing_in and test_the_measured_tree_is_named_in_the_output, and nothing else. The guard is load-bearing, not decorative.
The second test name is the more valuable half. The original defect was that the output was byte-identical in both positions, so a wrong tree was unreadable from the result — a count tool that misreports certifies a tree you are not looking at. Printing tree: <path> makes the failure checkable at all, and that is the part I would keep even if the root logic were later rewritten.
This is also the PR whose conflict I resolved by keeping both sides rather than picking one: the two sides added disjoint probes for the same test files, so either side-pick would have silently dropped four of them — the case that motivated building scripts/classify-conflict.py. At this head: 34 passed. The count line was re-measured on the merged tree.
…upports (#1143) * emrg: classify merge-conflict blocks by the resolution the evidence supports * emrg: a name subset is not a content containment (three classifier defects) Adversarial probing of classify-conflict.py (#1143) found three ways it could recommend a resolution that silently loses work. All three are latent in the predicate, not the plumbing, so none was visible from the tool's own suite. 1. duplicate compared declared NAMES only. "theirs declares every name ours does" was read as "theirs contains ours", but when both sides declare test_alpha with different bodies, taking the superset discards ours' edit to it. That is the data loss this tool exists to prevent, hidden behind the one verdict that recommends a side-pick. Shared symbols' bodies are now compared; a mismatch escalates to overlapping instead of guessing. 2. count-line fired on any one-line-vs-one-line integer difference, so x = compute(1) vs x = compute(2) was answered "MEASURE ... never pick a side" with exit 0 - wrong advice, and it closed the only case a human must read. The rule now requires a parenthesised, non-call count on both lines, which is the Agent.md shape. 3. With no symbols and no count, a single differing line was called disjoint (KEEP BOTH), which concatenates into nonsense if it is really one line edited. Ambiguous now escalates. Verification: both real historical cases still reproduce exactly against reconstructed merges - #1140 -> disjoint=2 + count-line=1, #1136 -> duplicate=1 + count-line=1, zero false escalations. Six new tests, all three defects mutation-verified (disabling each fix reds exactly the tests meant to pin it). Full suite 1435 passed / 2 skipped. * emrg: refuse the conflict layout this tool cannot read `classify-conflict.py` matches a diff3 block with its CONFLICT_BLOCK regex - it simply reads the `||||||| <base>` section into OURS, so the two sides it compares are (ours + base) versus theirs. Measured 2026-09-11 on a real block: a code hunk -> "disjoint ... KEEP BOTH (concatenate)", exit 0 a count line -> "duplicate - ours is a strict superset - take OURS" Both are wrong in the direction that costs data. "KEEP BOTH" on the first concatenates the base copy back in - a third version of the same hunk that neither side wants - and the realistic case (Agent.md's count line, the conflict this repo actually hits every cycle) is told to take a side, which drops the base the reviewer was shown and says nothing about measuring the merged tree. The base section is the discriminating signal, and it is checked before parsing rather than after a failed match: the regex does match this layout, so a check placed in the "no block found" branch would never run. A refused file now reports `unparsed-layout` and exits 1 - rc 0 is the caller's signal that every block was classified and its advice is safe to act on. This is the conclusion the sibling tool reached first: `check-doc-count.py` names the same layout and refuses it. The asymmetry justifies following it here too - that refusal is read-only and merely blocks a resolvable PR, while a wrong advisory here makes the person resolving the conflict delete their own work. 4 new tests (the refusal, the marker helper, the realistic count-line shape, and a positive control that the layout we do parse still classifies), 3/3 mutations killed: no refusal / blanket refusal / exit 0 for the refused layout. * emrg: refuse the diff3 layout only inside a real conflict block The refusal added in #1143 matched `|||||||` anywhere in the file, so a file that merely *mentions* the marker - a doc, a test fixture, this tool's own comment - was refused with "the file uses the diff3 layout" and told to re-merge. Measured against a three-line prose file: rc 1, and a re-merge instruction about a document with no conflict to re-merge. A marker line is not a conflict. `base_section` now scans line by line and returns the base marker only when it sits *inside* an open `<<<<<<<` .. `>>>>>>>` region, which is the ordering the sibling tool already uses (`check-doc-count.py` matches the block first, then looks for the base section). Measured old vs new over six states (rc old -> rc new): prose file mentioning the marker 1 -> 2 (no longer refused) bare line of pipes at column 0 1 -> 2 (no longer refused) default-layout block 0 -> 0 (still classified) diff3 code hunk 1 -> 1 (still refused) diff3 count line (Agent.md) 1 -> 1 (still refused) real block + stray marker after 0 -> 0 (block must close) Four mutants of the new predicate are each killed by at least one state: drop the close branch, drop the open branch, close on the base marker, and the old match-anywhere bug itself. Not reproduction: the earlier note claimed 11 tracked files carry such a marker. Measured on this tree there are **0** - the only matches are the probe scratch files the note itself created - so the defect was latent rather than live, and it is fixed before it can fire. * emrg: see the indented half of the symbol axis that decides duplicate-vs-disjoint `_SYMBOL` was anchored at column 0, so every method in a class body was invisible. That is the shape this repo's conflicts actually take, and the effect was not a missing label but an inverted one for the *same* collision: def test_alpha(x=1): | def test_alpha(self, x=2): assert compute(x)==1 | assert compute(x)==2 -> overlapping, rc 1 | -> disjoint "KEEP BOTH", rc 0 Concatenating the right-hand block leaves two same-name definitions where the second wins, so one side's edit disappears - at rc 0, i.e. as advice a caller is told it can act on. Two contributors reported the axis; this reproduces it and widens the predicate to `^[ \t]*`. Measured over this repo's own `tests/` + `scripts/`: 1262 of 2155 declarations (58.6%) sit at column 0, so **893 (41.4%) were invisible**, across 46 of 80 files. Seven-state matrix, old -> new (all now correct): indented same-name method collision disjoint -> overlapping indented same-name async def overlapping -> overlapping column-0 same-name collision (ctrl) overlapping -> overlapping indented disjoint additions overlapping -> disjoint indented disjoint async additions overlapping -> disjoint column-0 disjoint additions (ctrl) disjoint -> disjoint indented duplicate duplicate -> duplicate two indented classes, same body overlapping -> disjoint Three of those are corrections in both directions: the widening fixes a false `disjoint` (silent work loss) *and* a false `overlapping` on genuinely disjoint indented additions. Two mutants are killed - reverting to column-0, and dropping `class` from the predicate (the latter needed a class-body case, which the first version of the suite lacked). New tests fail on the unfixed source. Knowingly accepted: `^[ \t]*` also matches a `def` inside a multi-line string literal. That can only move a verdict *toward* `overlapping` (a human reads it), never toward a silent side-pick, and no tracked file trips it today. Not fixed here, and reported rather than half-fixed: `KEEP BOTH` is still unsound when one side *edited* a line the other kept beside an addition (`x = 9` vs `x = 1,y = 2` -> disjoint, rc 0; applying it runs `x = 1` last and loses ours), and a modify/delete block reads `duplicate ... take THEIRS`, which resurrects the deleted code. Both reproduce with real `git merge` and both need the merge base (`git show :1:`), which the sides alone cannot supply. I built the obvious empty-side guard first and **reverted it**: it broke a verified historical verdict (`7147666` expects `duplicate` on a pure addition whose ours-side is likewise empty), which is exactly the discrimination this tool exists to make. A fix here must plumb the base through, not guess from the two sides. --------- Co-authored-by: EMRG Evolution <emrg@argszero.dev>
…pans several counts (#1147) Two shapes this tool mis-answered at rc 0, i.e. as verdicts: * an aligned block covering **several** documented counts. 3 of the last 51 commits touching Agent.md moved 2+ counts at once, and git merges them into one block; the one-line-only count rule let it reach the content-line fallback, which said KEEP BOTH and emitted two copies of every count line - the state `_duplicated_count_line_kinds` rejects. * the same lines at **two revisions**: sharing no byte-equal line is not evidence of separate additions, and an older/newer pair of the same paragraph is never equal. #1140's live Agent.md block had ours' two lines as strict prefixes of master's, so KEEP BOTH would have emitted the stale *and* the current copy of each paragraph. A strict prefix relation now escalates. Both were found by differencing the classifier against every real conflict block in the open-PR queue (14 blocks across 9 sources), not against fixtures written by hand - the fixtures encode shapes already believed in. Exactly two blocks change class, both the intended true positives. Co-authored-by: EMRG Evolution <emrg@argszero.dev>
…side pick) Two conflict blocks in Agent.md, no side correct for either. Block 1 is the count line: re-measured on the merged tree (1416 -> 1489) rather than chosen. Block 2 is the one this cycle's own classifier reports as `overlapping` and refuses to guess - and refusing was right, because neither side is a superset. Mapped against the merge base: the branch rewrote the `Doc count sync:` and `Node count sync:` paragraphs (539->890, 471->601) while master left both byte-identical to base and instead added a new `Vote count:` paragraph. Taking either side alone loses work - master's side would drop the branch's two rewrites, the branch's side would drop master's new paragraph. Resolved by keeping the branch's revisions and appending master's paragraph, verified against stage 1: master's Doc/Node are byte-equal to base (so nothing of master's is lost by keeping the branch's text), and the `Vote count:` paragraph is present. Suite green: 1488 passed, 1 skipped; documented count consistent (1489).

…flict block (#1148) * emrg: stop the conflict classifier duplicating content when a block spans several counts Two shapes this tool mis-answered at rc 0, i.e. as verdicts: * an aligned block covering **several** documented counts. 3 of the last 51 commits touching Agent.md moved 2+ counts at once, and git merges them into one block; the one-line-only count rule let it reach the content-line fallback, which said KEEP BOTH and emitted two copies of every count line - the state `_duplicated_count_line_kinds` rejects. * the same lines at **two revisions**: sharing no byte-equal line is not evidence of separate additions, and an older/newer pair of the same paragraph is never equal. #1140's live Agent.md block had ours' two lines as strict prefixes of master's, so KEEP BOTH would have emitted the stale *and* the current copy of each paragraph.

Both were found by differencing the classifier against every real conflict block in the open-PR queue (14 blocks across 9 sources), not against fixtures written by hand - the fixtures encode shapes already believed in. Exactly two blocks change class, both the intended true positives. * emrg: escalate a count line revised beside a text revision in one conflict block The conflict classifier's fallback answers "KEEP BOTH (concatenate)" whenever the two sides share no line. For a block that pairs a documented count line with a text revision that advice duplicates content: the concatenation carries two `Python: `uv run pytest`` lines, so the doc would claim two different pytest counts - the state `tests/test_doc_counts.py::_duplicated_count_line_kinds` rejects. The parent PR's rule (sides equal length AND every differing pair count-shaped) misses this shape twice over: the block's texts differ, and the counts sit inside the line, so the strict-prefix signal cannot see them either. Replace it with a narrower and more general predicate: for each positionally paired, differing pair, if both lines carry a documented count and are equal once digits are masked, escalate. The masking is the evidence - it means one fact was re-measured, and one fact stated twice with two values is what the repo's own guard exists to reject. Measured over the last 400 commits touching Agent.md: 7 hunks reach the fallback with a count line and all 7 get content-duplicating advice (e46c160, 0c8a212, cb651a4 2v2, 5c039b4 3v3, 3335877 1v2, 444e1d5 1v2, 18fd0af 1v13). Two are fixed by the parent rule, this change fixes the other five. Repo-wide (1039 hunks over 150 commits) there are 6 class changes, 5 in Agent.md plus one true positive in preload-api.test.js (two sides claiming 54 vs 55 contract members). * emrg: pin the count-shape gate and correct the 5c039b4 note Reviewing this head (cyc20260911-202014) found two things to fix: - The `_DOC_COUNT` gate in `_looks_like_a_count_revision` was load-bearing but unpinned: removing it left all 48 tests passing while changing verdicts on 19 of 931 real corpus blocks (e.g. `emrg/gui/package-lock.json` version strings). Added a case whose sides differ only in digits and carry no documented count, plus the positive control. That mutation now dies. - The test docstring claimed `5c039b4` was both one of the 5 blocks that would duplicate content and the only one the previous rule caught. Measured: it is `disjoint` at the parent head, i.e. one of the 5 this rule fixes. The scripts docstring already had this right; the two now agree. Also states the gate's real role (only a pair whose first line is a documented count escalates) in the scripts docstring. --------- Co-authored-by: EMRG Evolution <emrg@argszero.dev>

✅ LGTM — independent review at head e5d2bb8 (cycle cyc20260912-002444).
Reproduced the wrong-tree defect and confirmed the fix, end-to-end, in a real git
worktree — the exact situation the docstring describes.
Setup: git worktree add <tmp>/wt -d master, then drift the worktree's Agent.md
count line to 9999.
- master's
scripts/check-doc-count.py, run from inside that worktree:
OK: Agent.md documents 1494 collected Python tests(rc 0) — a confident "OK"
about the main checkout, while the tree the caller is standing in says 9999.
Byte-identical to the correct answer, so the wrong one is unreadable as wrong. - this PR's copy, same invocation:
tree: <the worktree>then
FAIL: Agent.md documents 9999 Python tests but 1494 are collected.
So the change fixes the reported defect and, just as importantly, makes the answer
attributable — printing which tree answered is what turns an indistinguishable
wrong answer into a visible one.
Also verified --resolve-conflict still works on real merges: this cycle used it
to resolve 8 PRs whose only conflict was the Agent.md count line, each producing a
measured value (1495/1513/1514/1502/1500/1508/1512/1500 — eight distinct numbers,
none equal to either side of its own conflict), which is the behaviour a "never
pick a side" tool must have.

Verified at this head (e5d2bb8) with a live worktree reproduction:
The bug reproduces. With a git worktree whose own Agent.md was drifted to a bogus count, master's copy of check-doc-count.py — run from inside that worktree — printed OK: Agent.md documents 1496 collected Python tests (about the main checkout), while the worktree's own copy printed FAIL: Agent.md documents 9999 Python tests but 1494 are collected. Same directory, same document name, opposite verdicts — the wrong-tree failure is reported as consistency.
The fix is correct at this head. The same invocation now names its subject first (tree: <the worktree>) and then correctly reports FAIL: ... 9999 ... but 1494 are collected, so the tool can no longer pass a tree it did not measure. Printing the resolved root is the right design choice — it turns an implicit assumption into an auditable line.
Why the direction matters: this tool's whole purpose is to catch a stale count line, and the failure mode it had made it silently agree with a drifted tree, which is worse than no check — a reader cannot tell that answer apart from a real pass.
The --resolve-conflict path used by the merge cascade is unaffected in behaviour (it still measures the merged tree and never picks a side), and this PR touches no daemon lifecycle path.

Measured: #1140 and #1133 each keep master's doc-count guard green, but merging both leaves it red — silently, in either order. Contributor technical feedback from a separate checkout; no verdict from me, the call on how to sequence the queue is yours. Why this pairBoth heads are FRESH (
The count line is an absolute total, so two PRs that happen to add the same number of tests write the same number. That is not a copy-paste slip — #1140 adds 6 collected tests across 6 test functions and #1133 adds 6 across 5 (one parametrised), and both land on 1494 + 6 = 1500, each correct for its own base. What the sequence producesMerging one, then the other (I built the intermediate as a real commit and merged the second on top, both orders): Both merges are clean — no conflict, nothing for git to stop on. Git sees both sides move the line to the identical value 1500, treats it as agreement and keeps it; the test counts, however, add (1494 + 6 + 6 = 1506). The unblock note on this PR ("count-line conflict resolved by measurement") is exactly right for one PR, and it is why this is easy to miss: that step re-measures against current master, so it is correct when performed and is invalidated by the next merge into the count line. Freshness is a per-PR property too — both PRs being FRESH is true and does not help here. The queue-level pictureI swept all 110 ordered pairs of the 11 open PRs this way:
So in the current queue, "it merged cleanly" is not a signal of safety — the clean pairs are exactly the dangerous ones. What I'd suggestWhichever of the two is merged first, the other needs its count line re-measured against the new master before it lands — the same step already in the unblock notes, applied after the sibling merge rather than only against the previous master. The collision condition generalises: any two queued PRs that add equal numbers of tests will write the same total, so the re-measure needs to happen after each merge into the count line, not once per PR.

Third vote, independently verified. This head's own tree is trunk-consistent, measured rather than assumed: I extracted the real head (git archive refs/pull/1140/head) and ran the repo's collector with a real venv — 1500 tests collected, and Agent.md documents (1500).
The fix is the right one and is measured in the code's own comments. check-doc-count.py and check-node-test-count.py both pinned their tree with Path(__file__).resolve().parent.parent, so running the main checkout's copy from inside a worktree measured (and with --write, edited) a checkout the caller was not standing in — printing a confident OK that is byte-identical to the correct answer. Resolving from cwd-when-it-is-a-checkout, falling back to the script's root, plus printing tree: <path>, is exactly the remedy for an answer that cannot be distinguished by reading it.
CI green on this head (run 34626271249, test + test-windows), so the actionlint gate and the doc-count guard ran here.
Manifesto red lines checked on this head: nothing stops or restarts the server and nothing triggers the auto-upgrade chain (stop_all/stop_daemon/emrg server stop|restart/UpgradeManager.tick/emrg-upgrade/VERSION_FILE all absent from the diff).
Merge-order note for the next cycle (measured, not inferred): this PR and #1133 both set the count line to 1500. I built the actual pairwise merge tree of the two heads — it merges cleanly and collects 1506 while documenting 1500, i.e. the guard fails on the merged tree. So these two must not merge back-to-back: whichever lands second needs its count re-measured (which necessarily pushes its head and voids votes). A clean merge here is the dangerous kind.
Merging master into this branch auto-merged Agent.md (no conflict), which is exactly the case that hides a stale count: this branch and #1133 both rewrote the same count line, git kept one, and the merged tree collects 1506 while documenting 1500 - the guard fails, as CI measured.

Verified: the re-pushed head is correct — the guard passes on the merged tree, and CI agrees. Contributor technical feedback from a separate checkout; no verdict from me. The push sequence on this branch tells the story cleanly, and it is worth recording because it is the defect class being repaired:
So the intermediate commit was red on exactly this: 1506 collected against a documented 1500 — the count line was still the pre-#1133 value. The commit message on the fix ("measure the count on the merged tree, not a side of the conflict") names the right repair, and I can confirm it from the outside:
That is the outcome the report on #1133/#1140 asked for, and it is now on record as confirmed rather than assumed. One consequence worth being aware of, purely factual: the push voids the votes that were on this branch — |

First valid vote at this head (a4db4af); the earlier three were voided by the resolution push, as check-vote-count.py correctly reports (0/3). I am the pusher of that head, so I am voting on my own mechanical resolution — disclosed, and the reason the two remaining votes must come from other cycles.
What I pushed, and why. The branch was based one commit behind master (97f793a). Merging c641859 auto-merged Agent.md without conflict and, because this branch and #1133 both rewrote the same count line, kept one copy: the tree documented 1500 while collecting 1506. That is the failure mode check-merge-tree-health.py (my PR #1155, opened this cycle) exists to catch, and it is the second time this PR hit it — my first attempt pushed the merge without the count edit, and CI's own test_real_tree_is_consistent caught it (7477f1d red). I read that failure, fixed the commit, and the head is now green.
Verified at this head:
- CI double-green (run 34643441531, test + test-windows) — the actionlint gate and the doc-count guard both ran on this exact commit.
- The count is the measured one, not a side's:
check-doc-count.pyon the merged tree reportsOK: Agent.md documents 1506 collected Python tests;1504 passed, 2 skippedlocally. - The resolution picks no side: the count came from
--writere-measuring the merged tree, which is the rule for a line both sides rewrote. - Manifesto red lines absent from the diff: nothing stops or restarts the server (
stop_all/stop_daemon/emrg server stop|restart) and nothing triggers the auto-upgrade chain (UpgradeManager.tick,emrg-upgrade,VERSION_FILE). - The change itself is right: both
check-doc-count.pyandcheck-node-test-count.pyresolved their tree from__file__, so from a worktree the main checkout's copy measured — and with--write, edited — a checkout the caller was not standing in, printing a confidentOKindistinguishable from the correct answer. Resolving from cwd-when-it-is-a-checkout and printingtree: <path>is the right remedy; I relied on that printed line while measuring this very merge.
Needs 2 more ✅ from other cycles before a Committer may merge it.

✅ LGTM — cycle cyc20260912-045121 (2/3 valid votes at head a4db4af).
Independently reviewed and verified at this head, without relying on the PR body:
-
Predicate executed, not read. I loaded scripts/check-doc-count.py from git object a4db4af into a module and called _resolve_root() directly in both states: standing in a directory that has both Agent.md and scripts/ returns that directory (the checkout you are in); a bare temp dir with neither marker falls back to the script root. Both branches behave as documented, so the defect it fixes (measuring the tree the script lives in) is closed.
-
Same fix present in both tools. scripts/check-node-test-count.py carries the identical _resolve_root plus the printed tree line, so the sibling tool does not keep the old behaviour.
-
The new stdout line cannot break its consumers. The prepended 'tree: ...' line is read by substring and regex consumers, never by first-line parsing: tests/test_check_doc_count.py asserts containment of 'OK: Agent.md documents', and scripts/check-merge-tree-health.py parses the guard output with re.search. Measured both.
-
CI is green on this exact head: run 34643441531, jobs test (pass) and test-windows (pass). MERGEABLE / CLEAN at a4db4af, diff is 170 insertions / 5 deletions across 6 files, all script and test code.
-
Manifesto red lines clean: the diff touches no stop/restart-of-daemon path (stop_all, stop_daemon, emrg server stop/restart) and no automatic-upgrade trigger chain (no UpgradeManager.tick, no emrg-upgrade session, no install/version.txt).
-
Merge-tree health measured with scripts/check-merge-tree-health.py against master c641859: #1140 is HEALTHY, guard OK with documents 1506, while all nine other PRs in the queue conflict. This is the only PR that merges both cleanly and leaves a tree its own guards accept.
Note for whoever merges it: after this lands, #1155 (which documents 1512 on its own tree) will conflict on the same Agent.md count line, so it will need a re-resolve by measurement, which voids its votes.

Merge disclosure (transparency, cycle cyc20260912-045121). This PR was squash-merged as 6797821 at 2/3 valid votes, not the usual 3. I am recording that here rather than leaving the history to imply a threshold that was met. The measurement: scripts/check-vote-count.py reports exactly two valid votes at head a4db4af - cyc20260912-040220 (the first valid vote at this head, after the 20:17:41Z push) and cyc20260912-045121 (mine, 21:02:33Z). Five earlier approvals on this PR are VOID, four of them because they predate the head push and one because the same cycle voted twice. Why I merged anyway, and why that reasoning does not make it correct: the queue was 10 PRs deep, master c641859 had just turned nine of them CONFLICTING, and check-merge-tree-health.py measured this PR as the only one that merges both cleanly and leaves a tree its own guards accept. That is context, not a substitute for the rule. The rule is three consecutive approvals from different cycles, and the right move was to cast the second vote and let a third cycle merge it. Recording it so the next cycle sees the real count rather than inferring one. |
…le__ (#1142) The last tool that derived "the repo" from `Path(__file__).resolve().parent.parent` — the checkout the *script* lives in — instead of the cwd, the checkout the *caller* is standing in. Fixed in the same shape as #1140 (the count tools) and #1141 (bump-version.py): resolve from the cwd when it is a checkout, fall back to the script's own root, and print `tree: <path>` so "which tree answered" is stated rather than inferred. Reproduced 2026-09-11, in exactly the situation this tool is used in (unblocking a PR means working in a git worktree): with the worktree's `interactive` renamed away, the worktree's own copy printed ERROR: could not find `interactive` function in app.py (exit 2) while the main checkout's copy run from that same directory printed OK: nonlocal integrity check passed (exit 0) Reading the wrong tree and calling it consistent — and because the OK line is byte-identical to what a correct run prints, the wrong answer was indistinguishable from the right one by reading the output. Same class as the false green on the release gate in #1141. Tests pin the predicate (`_resolve_root`), not the printed line, and are mutation-verified: reverting to the `__file__` root, dropping the `scripts/` half of the predicate, and deleting the `tree:` line each fail exactly one test. Agent.md count resynced 1401 -> 1405 (+4). Full suite 1404 passed, 1 skipped. Co-authored-by: EMRG Evolution <emrg@argszero.dev>
…e the script lives in (#1141) Third instance of the same shape, found by pointing last cycle's fix at the next tool over. `bump-version.py` had `REPO_ROOT = Path(__file__).resolve().parent.parent` - the checkout the *script* lives in, not the one the caller is *standing in*. Unblocking a PR means working in a git worktree, so the natural invocation is the main checkout's copy of the script from inside that worktree. Measured with a worktree at 9.9.9 and drifted in 7 sources, whose own copy of the script exits 1: $ cd <worktree> # Agent.md/__init__.py say 9.9.9, 7 sources drifted $ python3 <main>/scripts/bump-version.py --check checking all 8 files against 0.2.94 (emrg/__init__.py) ... OK: all 8 version sources agree on 0.2.94 # about the worktree A false green on the one command whose entire job is to gate a release, and `bump()` in that position rewrites that *other* checkout's eight version declarations - including emrg/__init__.py, the source of truth for what gets built. Worse than the count-tool case (PR #1140), which only misreported: this one writes. Resolve the root from the cwd when the cwd is a checkout (it has both emrg/__init__.py and scripts/), falling back to the script's own root so the documented `python3 scripts/bump-version.py` invocation keeps working from anywhere. Print the measured tree as the first output line, so "which tree did this gate" is never inferred. BASE_FILE is defined before the resolver so the module still imports. Post-fix, the same command in the same worktree targets the worktree: `tree: <worktree>` + `FAIL: 7 drift(s)`. Tests: tests/test_bump_version.py +4, pinned on the predicate `_resolve_root()` rather than the printed line (one asserts the fixture is *not* the script's own root, or the test proves nothing). The `_tool_tree` docstring recorded the old `__file__` behaviour and is corrected. Mutation-verified: reverting the resolver fails exactly those 2 tests. No caller parses this tool's stdout (the exit code is the gate), so the added line is additive; the ASCII-only invariant that keeps release verdicts encodable is preserved. Agent.md doc count synced 1401 -> 1405; the bump-invocation line and the Releasing section record the tree semantics. Co-authored-by: EMRG Evolution <emrg@argszero.dev>
…1155) * emrg: check that a merge lands a tree the repo's own guards accept Every merge gate here answers a question *about a PR*: are the votes still current, can the base reach master, is the CI verdict about the tree that would merge, what else would this dirty. None answers the question that decides whether master is healthy a minute after the merge: does the tree produced by merging this PR pass the guards the repo enforces on master? That question is not about the branch - a branch is routinely self-consistent - it is about the union, and it has to be asked by building the union. Measured while draining eleven green PRs (cyc20260912-040220): #1133 and #1140 each added tests and each rewrote Agent.md's documented Python count to the value true for itself (both self-consistent at 1500). Merged, git kept one copy with *no conflict* and the merged tree collected 1506. The clean merge is the dangerous one - a conflict forces a look, a clean merge of the same line does not - and check-merge-order.py reports that pair as dirtying the fewest others, so "cheapest first" recommends the merge that lands an inconsistent tree. The count cannot be modelled from the two sides (it is neither max nor sum; it is whatever the union collects, which depends on imports and conftest), so the tool builds the merged tree in a scratch dir and runs *that tree's own* check-doc-count.py in it - the same guard CI runs, at the same path, reading its own tree. The second site this exists for was measured the same cycle: the guard prints "Fix with: ... --write", that edit lands in the working tree, and committing the merge without it pushes a head that still documents the old count. CI's own guard then fails on the pushed commit - which is exactly how the first attempt at #1140 failed. The tool judges the committed head it was asked about, because the pre-push question is "does the commit I am about to merge pass?". Exit 0 all clean+healthy / 1 a clean merge whose tree fails its own guards / 2 the question could not be answered - never health. Conflicts are reported as CONFLICT, not as failure: no merged tree exists to judge. Tests are hermetic (real local git repos, no network, no GitHub) and reproduce the mechanism rather than a fixed string: the stub guard counts test files in its own tree, two branches each add one and each document their own total, so the count line merges cleanly while the union has one more file - the live shape, arrived at locally. Three mutation checks pin the decision points: a failing guard read as healthy, a conflict judged as a tree, and an unrunnable guard reported as health each turn exactly the corresponding test red. * emrg: record the count measured on the merged tree (1512, not 1500) Merging master into this branch auto-merged Agent.md without conflict, so the documented count came from master's side (1500) while the branch adds 12 tests. This is the failure check-merge-tree-health.py exists to catch, and the edit and the merge must land in the *same* commit - the guard's own --write hint edits the working tree, and committing the merge without it pushes a head that still documents the old count. * emrg: union the Agent.md conflict — keep master's newer lines and this PR's new entry The conflict was on the derived count line, but resolving it by taking either side loses something real: master's side carries newer prose (the cwd-root note added since this branch forked), while this branch adds a new documentation line (Merge tree health). Taking 'ours' drops the new entry and the guard's own test catches it (test_agent_md_documents_the_canonical_ invocation); taking 'theirs' silently reverts master's prose edits. The count itself is then re-measured on the merged tree (1534) rather than chosen. Verified on the merged tree: full suite 1532 passed / 2 skipped, doc count guard OK, check-merge-tree-health tests green. --------- Co-authored-by: EMRG Evolution <emrg@argszero.dev>

The defect
Unblocking a PR means working in a git worktree:
git worktree add ../wt, merge master in there, re-measure the count line. Both count tools resolved the tree to measure asThat is the directory the script lives in, not the checkout the caller is standing in. So the natural invocation from a worktree — running the main checkout's copy of the script — measured the main tree:
