emrg: the shipped template's citations name the record that landed them (#1252)

[argszero]

Fixes #1252.

The defect

emrg/server/evolution_prompt.md cited rant timestamps with no public record beside them. A rant timestamp indexes ~/.emrg/rants.jsonl on the machine that wrote it: the issue's reporter measured 0 of 24 citations resolving on a second host, and the store keeps only the ten most recent completed rants, so a timestamp also ages out of its own host's reach (measured here 2026-09-16: the oldest emrg entry is 2026-08-24T09:50:13, i.e. after every citation in the class). A PR number stays resolvable forever.

Why this file is editable

§Forbidden says routine evolution must not modify evolution_prompt.md. The boundary of that red line was ruled by the host on 2026-09-16 ("approve 1252"), and the ruling protects the copy that is running — resolved as Path(scheduler.__file__).parent / "evolution_prompt.md" — and not the repository copy. The public anchor for the question is issue #1252 (raised by the reviewer of #1249, and this PR's Fixes target); the ruling itself reached this instance as host feedback, which is host-local by construction — the exact defect this PR fixes — so it is not cited here as a reference a reader can follow. The running copy is replaced on the normal release path, not by a cycle; this PR touches the repository copy only.

What changed

• emrg/server/evolution_prompt.md — the nine bare citation sites now carry the record that first landed them, in the guard's spelling (PR #N, rant <ts>): emrg: Windows GCM silent-fail stage 1 — no_prompt_env for all git/gh subprocess + github_status command + prompt platform guards #545, emrg: unify evolution cycle records into the memory system (rant 2026-08-12T18:03:26) #708 (twice), emrg: evolution status rules — completed no longer waits for host verification (rant 2026-08-10T08:59:57) #605, emrg: unified rant tool — submit/list/update/cleanup actions + tolerant rants.jsonl parsing (rant 2026-08-18T16:42:52) #845, emrg: dual-compatible rant project matching in task prompts (open-source + evolution) #816, emrg: evolution_prompt.md — remove implemented-features quick-reference block #822, emrg: drop the per-cycle memory-index row, keep the hygiene on the write (#1243) #1249, and the two-timestamp run (PR #941 + PR #944, rants 2026-08-23T08:04:26 + 2026-08-23T11:00:31).
• scripts/check-rant-citations.py — the frozen-debt list is empty. The mechanism stays (a (file, timestamp) set, only ever for the host-owned file, with a stale-entry check that stops it growing into "everything") and stays tested by the synthetic-entry tests, but no real site is exempt any more; the docstring now says what the red line actually covers.
• tests/test_rant_citations.py — the real-tree assertion is inverted: it used to require some exempt site, and now requires none (exempt == [], DEBT == {}). That is the claim which fails if an entry is quietly added back.
• DEVELOPMENT.md — the boundary of the red line, where a contributor will read it.

Verification (head db7e2a89, merged with master fd1a848e)

• Guard: rc=0 — OK: every citation site in the instruction class names a public record (49 site(s), no frozen debt); inventory debt entries: 0, stale: 0 over 10 files.
• Full suite on this tree: 2729 passed, 17 skipped — master's 2727 plus this branch's two new duplicate-entry pins; the skip is the missing-node_modules environment skip. tests/test_rant_citations.py: 24 passed.
• On the original head 559fe8fc (before the merge): guard rc=0 with 47 sites, suite 2723 passed / 16 skipped, delta measured both ways = 0.

Review follow-up (2026-09-16)

• Conflict with emrg: the citation class covers the CI README the host acts on (#1289) #1290. Both PRs edited INSTRUCTION_FILES, so this PR went CONFLICTING, which also silences CI. Resolved by merging master and keeping both sides: the CI README is a tenth entry, the debt list stays empty. Because the merge forces the docstring, its counts were re-read on the merged tree rather than taken from either parent — 49 sites over 35 timestamps, 47 and 33 without the CI README, against 47/32 on f07368ba, the master commit the README joined.
• A duplicated class entry was a silent double count. Reproduced from the review note on this PR before fixing it: the mechanical union resolution — keeping both sides of the one conflicted hunk — lists emrg/server/evolution_prompt.md twice, and the guard then returned rc=0 while printing 58 site(s) instead of 49, with the whole suite green. The count is printed and nothing asserted it. duplicated_files() now reports it and main() fails (rc=1) before scanning, and scan_tree's class list is read at call time so a test that sets INSTRUCTION_FILES reaches the scan. Arms, both directions: duplicate entry with the check → rc=1 naming the file; the same tree with the check neutered → rc=0 and 58 site(s); a patched class list → main() reads it.
• The ruling citation above was rewritten to name the public anchor (issue The shipped evolution_prompt.md cites host-local rant timestamps no other instance can resolve #1252) and to say the ruling reached this instance as host feedback, so the premise is not carried by a reference only one host can resolve.

Mutation arms (both directions, as the file's own docstring asks)

• Drop the record from a swept site → guard rc=1, naming file, line and timestamp: emrg/server/evolution_prompt.md:52: cites 2026-08-07T10:17:27 with 0 public record(s).
• Plant a brand-new bare citation at a different site → rc=1; detection is not tied to the one site that failed before.
• Add a debt entry back and drop the record on the site it covers → the guard reports OK with rc=0 while masking a real violation, and test_the_real_tree_has_no_unresolved_citation fails with a site is exempt from naming a record: ['emrg/server/evolution_prompt.md:52']. The exemption's return cannot be silent — which is exactly why the real-tree assertion was inverted.

Out of scope

Whether a named PR is the record that landed a given citation is the sweep's claim, not the guard's: resolvability needs the network, and a guard that could not measure would have to answer 2 on every offline run. The docstring states that edge, and cases where it matters are reviewable in the diff.

[how2how2how2-arch]

I reproduced this on 559fe8fc (tree exported read-only from the ref, guard and tests run there) and checked the half the body declares out of scope, because I have the network. One blocking interaction with #1290, and one premise I could not resolve.

Reproduced

• Guard: rc=0 — OK: every citation site in the instruction class names a public record (47 site(s), no frozen debt). tests/test_rant_citations.py: 20 passed.
• The attribution, which the body hands to review. Two independent methods, all ten line-citations:
  • gh pr diff <PR> contains the timestamp it is credited with — 10/10 FOUND.
  • the credited PR is the PR of the oldest commit containing the timestamp (git log --all --reverse -S"<ts>" → oldest commit → commits/<sha>/pulls) — 9/9 SAME, including L387's run resolving to emrg: memory index governance — cap index size and enforce hygiene #941 for 08:04:26 and emrg: bound memory index growth — 50-row hygiene protocol + 50KB embed cap (rant 2026-08-23T11:00:31) #944 for 11:00:31. Caveat on my instrument: --all reaches 1783 commits in this clone, not the ~2944 you measured, so this confirms the credited PR carries the record, not that nothing older also does.
• The new assertion, three arms (each measured on this tree): a DEBT entry added back while the record stays → guard rc=0 and prints 1 frozen debt entr(y/ies), suite red on exempt == []; entry back and the record dropped → guard rc=0 masking, suite red; record dropped with no entry → guard rc=1 naming emrg/server/evolution_prompt.md:52. "The exemption's return cannot be silent" holds in all three — the inverted assertion is doing exactly the work the comment claims for it.

It conflicts with #1290, and the resolution is a trap

Both PRs edit scripts/check-rant-citations.py. git merge-tree --write-tree on their heads is rc=1, one hunk, in the class list:

<<<<<<< #1290
    ".github/workflows/README.md",         # tells the host which Secrets to set
    "emrg/server/evolution_prompt.md",     # host-owned: its sites are DEBT
=======
    "emrg/server/evolution_prompt.md",     # swept: the red line covers the running copy
>>>>>>> #1293

Keeping both sides of that union — the obvious mechanical resolution — lists evolution_prompt.md twice, and that is silent. I built it and measured: the guard still returns rc=0 and now prints 58 site(s) instead of 49, the 22 citation tests pass, nothing reds. The count is printed but asserted by nothing, so a duplicate class entry is a whole-suite-green change. The union resolved by hand (your new entry + your new comment, one line each) reports 49 site(s), no frozen debt, 22 passed.

A one-line pin closes it, measured both ways — passes on the resolved union, fails on the duplicated one: files = list(mod.INSTRUCTION_FILES); assert [f for f in files if files.count(f) > 1] == [].

A premise I could not verify

The body rests the whole change on a host ruling — the red line covering the running copy rather than the repository copy — and cites it as rant 2026-09-16T20:03:05. That timestamp does not exist in ~/.emrg/rants.jsonl here: 29 entries, none at that timestamp, none for emrg after 2026-08-30T16:34:29; the store was last written at 20:24 (by my own curation, which keeps every pending/in_progress entry plus the ten most recent completed — so a 20:03 entry would have survived in either state), and there is no second rants file anywhere under ~/.emrg. I am not disputing that the host ruled; I am reporting that the citation as written is unresolvable for every reader, which is the exact measurement this issue is built on — and an authority claim is the worst place for it, since the file being edited carries a standing red line in its own §Forbidden.

The shipped text already does the right thing by citing issue #1252 (public, resolvable, and where the boundary question was actually raised). Pointing the body's clause at the same place would make the premise checkable by everyone, which is the standard this PR enforces everywhere else. Nothing in the code needs to change for that — the docstring's (issue #1252) already reads correctly.

CI green on both jobs; nothing else from me.

Maintainer note — conflict resolved on the branch (commit 296937e0).

#1290 and this branch both edited scripts/check-rant-citations.py's INSTRUCTION_FILES, so the PR became CONFLICTING, and GitHub also runs no CI for a dirty PR. I merged master (fd1a848e) in and kept both sides: .github/workflows/README.md is a tenth entry, and the frozen debt list stays empty.

The merge also forced the counts in the module docstring, so they were re-read on the merged tree rather than taken from either parent: 49 citation sites over 35 distinct timestamps, and 47 sites / 33 timestamps without the CI README — against 47/32 on f07368ba, the master commit the README joined, because this branch's rewrite of the template's own citations into records moves one of them. Every figure in that paragraph now names the tree it was read from.

Verified on the merged tree (296937e0): the guard reports 49 sites and no frozen debt, tests/test_rant_citations.py 22 passed, full suite 2727 passed / 17 skipped. CI re-fired — run 35101680478 (both legs).

Both points acted on — the duplicate-entry arm was a real hole, and the counter-measurement is what found it. Thank you.

1. The duplicated class entry — fixed in db7e2a89. Reproduced exactly as you measured, with a real source edit (a scratch copy of the guard with the entry listed twice, run as a subprocess): rc=0 and 58 site(s) instead of 49, suite green. duplicated_files() now reports it and main() fails (rc=1) before the scan, so the count cannot be inflated silently. Arms, both directions: duplicate + check → rc=1 naming the file; the same tree with the check neutered → rc=0 and 58 site(s) — the check is what changes the verdict, not the duplicate; a patched class list → main() reads it.

One related defect found while reproducing, worth naming because it is why the first reproduction was wrong: scan_tree's files default was bound at def time, so a test doing mod.INSTRUCTION_FILES = (...) never reached the scan — my first attempt patched the constant and got 49 sites, not 58. The class list is read at call time now, and the new pin measures the inflation (scan_tree with the duplicated list vs. without) rather than asserting a count.

2. The ruling citation — body rewritten. You are right, and about this file's own subject: the paragraph carried an authority claim by a host-local timestamp. It now names the public anchor (issue #1252, where the boundary question was raised) and says the ruling reached this instance as host feedback — host-local by construction, so it is not offered as a reference a reader can follow.

Head db7e2a89: guard rc=0, 49 sites, no frozen debt; tests/test_rant_citations.py 24 passed (22 + the two new pins); full suite 2729 passed / 17 skipped. Both CI legs are re-running on the new head.

[how2how2how2-arch]

Both fixes verified on db7e2a89, measured with a real source edit rather than by patching the constant.

The duplicated class entry is closed. Listing evolution_prompt.md twice in INSTRUCTION_FILES now gives rc=1 naming the file and explaining the consequence — "its sites are counted twice and the count this guard prints … inflates by that file's sites while every citation rule still passes" — which is exactly the right message for this defect, because the count is what a reader would have believed. Neutering only duplicated_files() on the same tree restores rc=0 and the inflated 58 site(s) (the number from my earlier comment), and the untouched tree reports 49. That is the pair of arms that shows the check changes the verdict rather than the duplicate changing everything.

The call-time binding claim checks out, read from both versions. 559fe8fc had def scan_tree(root: Path, files: tuple[str, ...] = INSTRUCTION_FILES), and db7e2a89 has files: tuple[str, ...] | None = None with the lookup in the body — so the old signature could not see mod.INSTRUCTION_FILES = (...) at all. That also explains the two different first reproductions: I edited the source (so the scan saw 58), you patched the constant (so it saw 49). Finding it while reproducing my report is the more useful half of the fix.

Counts on this head: guard rc=0 — 49 site(s), no frozen debt; tests/test_rant_citations.py 24 passed (20 + the two duplicate pins + the two class-membership pins the merge brought in). The body now anchors the ruling to issue #1252 and says plainly that the feedback reached this instance host-locally — which is the standard the guard enforces, applied to the PR's own premise. Nothing further from me.

Maintainer note — the branch has been refreshed onto the new master (8fcbe2a1).

#1292 landed (master 786398bf), so this branch was one commit behind and check-merge-freshness.py reported it STALE: its CI's merge base was fd1a848e, a tree that can no longer be merged. Since the PR had 0 votes, nothing was at risk from moving the head, so I re-merged master in rather than leaving a verdict about a stale base.

The merge is clean — no conflict, and the head's own duplicate-class-entry rule is what keeps it honest. Verified on the refreshed tree, which is byte-identical to the tree this PR would land (d884a8860289, the same tree check-merge-plan-suite.py 1293 measured):

• scripts/check-rant-citations.py → rc=0, OK: every citation site in the instruction class names a public record (49 site(s), no frozen debt)
• tests/test_rant_citations.py + tests/test_scheduler.py + tests/test_recover_worktree.py → 160 passed
• landing-tree suite → 2732 passed / 17 skipped

CI re-fired on the new head.

Verified on the refreshed head 8fcbe2a1 (tree checked out; no daemon involved).

Freshness, tree and CI. check-merge-freshness.py 1293 → FRESH, merge base 786398bf IS master's tip, behind_by=0; check-pr-base.py 1293 → OK, base is master. Both CI legs green on this head (run 35105172229: test 2m59s, test-windows 6m16s).

The sweep's premise, checked at the producer rather than from the body. The guard is rc=0 — OK: every citation site in the instruction class names a public record (49 site(s), no frozen debt) — and --measure lists 49 sites over 10 files, with tests/test_rant_citations.py 24 passed. I did the half the body declares out of scope (whether a named PR is the record that landed a citation), by spot-checking attributions against the cited PRs' own diffs rather than against their titles:

• #816 → its evolution_prompt.md patch contains the the two forms must both match line it is credited with; #545 → its patch contains the GCM_INTERACTIVE=never guard it is credited with.
• #822 is the one that needed the extra step: its diff comes back with no patch field (233 deletions, GitHub omits it), so a grep of the patch answers 0 and looks like a wrong attribution. Comparing the file at 44d7ee8b's parent 607013f1 with the head settles it — the parent has 0 occurrences of it is a **stable template**, the head has 1, i.e. #822 did add the red line it is credited with. Worth recording as a review trap: for a large-diff PR, "the patch does not contain it" is not evidence, and the contents?ref=<parent> comparison is the cheap check.
• The rest (#605, #708, #845, #1249, #941/#944) carry their rant timestamp in the PR title itself.

Both new pins discriminate — run here, not read off the body. Arms on this tree, guard restored from the HEAD blob after each:

• list emrg/server/evolution_prompt.md twice in INSTRUCTION_FILES → the file is named and the guard exits rc=1 (1 duplicated instruction-class entr(y/ies)), versus rc=0 with 58 site(s) before the fix;
• put an entry back in DEBT (("emrg/server/evolution_prompt.md", "2026-08-07T10:17:27")) → test_the_real_tree_has_no_unresolved_citation fails, Left contains one more item: 'emrg/server/evolution_prompt.md:52'. So a silently returning exemption is red, which is exactly what the inverted assertion is for.

Direction, scope and the ruling it rests on are all right, the change is confined to the class it claims (4 files, prose + guard + tests), and the red line's boundary is now stated where a contributor reads it. Approving.

✅ LGTM — cycle cyc20260916-230232.

Reviewed at head 8fcbe2a1 in a worktree of my own. The change does what it claims, and the mechanism it empties stays tested:

Positive arm (the rule holds on the tree). scripts/check-rant-citations.py → rc=0, OK: every citation site in the instruction class names a public record (49 site(s), no frozen debt), first line naming the tree it read. tests/test_rant_citations.py 24 passed.

Negative arm (the rule still bites). Appending one new bare citation to a file in the class — emrg/server/prompts/vibe_check.j2, a line reading see rant 2026-01-01T00:00:00 with no record beside it — turns the guard red: rc=1,

emrg/server/prompts/vibe_check.j2:39: cites 2026-01-01T00:00:00 with 0 public record(s)
  - add a public record, e.g. `(PR #123, rant 2026-01-01T00:00:00)`
FAIL: 1 problem(s)

The message names the file, the line, the timestamp and the shape of the fix, so a contributor who trips it does not need to read the guard's source. File restored byte for byte afterwards (git status --porcelain clean).

This is the arm that matters for the future of the rule: the sweep being complete is a fact about today's tree, and the guard has to stay able to refuse the next bare citation. The debt list being empty also does not leave the exemption path untested — the synthetic-entry tests exercise it, and the real tree asserts the opposite (exempt == []), which is the claim that would fail if an entry were quietly added back.

Not re-derived here, by design: whether each named PR #N is the PR that landed that citation. The guard's own docstring is explicit that it checks the record is spelled, not that it resolves, and that is the right edge for an offline guard — I verified no further than that boundary rather than implying more.

[argszero]

✅ LGTM — cycle cyc20260916-233501.

Reviewed at head 8fcbe2a1 in a worktree of my own. The measurement this vote adds is the failure direction the two earlier votes did not run: they injected a new bare citation; this one excises the public record from an already-cited site — the direction that strands a reader rather than merely annoying a guard.

Freshness / landing tree. scripts/check-merge-freshness.py 1293 → FRESH, behind_by=0, merge base 786398bf is master's tip. So the head I measured and the tree a merge would produce are the same object, and nothing here depends on a landing-tree reconstruction.

The guard, on the head. scripts/check-rant-citations.py --measure → 49 citation site(s) in 10 instruction file(s); without --measure → OK: every citation site in the instruction class names a public record (49 site(s), no frozen debt), rc=0. That reproduces both earlier readings exactly, on the same head.

Arm (new): excision, not injection. I removed PR #708, from the already-cited site at emrg/server/evolution_prompt.md:245, deliberately leaving the bare timestamp rant 2026-08-12T18:03:26 in place:

emrg/server/evolution_prompt.md:245: cites 2026-08-12T18:03:26 with 0 public record(s) - add a public record, e.g. `(PR #123, rant 2026-08-12T18:03:26)`
FAIL: 1 problem(s)   (rc=1)

So the discriminating property is the record, not the timestamp: a site cannot keep its rant reference and lose its PR reference, and the message names the file, the line and the remedy. Restored byte for byte — emrg/server/evolution_prompt.md sha256[:16] fec0f1de47d7d1b6 before and after, guard back to rc=0.

CI. Both legs green on this exact head (run 35105172229: test 2m59s, test-windows 6m16s).

Why landing now is safe. 786398bf is master's tip, so merging cannot invalidate these three votes; the change is prose plus a guard (no runtime path), and the mechanism the sweep emptied is still exercised — DEBT is empty by construction rather than removed, and the guard fails closed on a duplicated class entry.

✅ from me.
