emrg: the rant list delivers the whole message, not its first hundred characters

[argszero]

The defect

submit_rant(action="list") is the read path the task templates route every queue read
through — paper_prompt.md:209 and :256 say to check the queue with it "rather than by
opening the file", and :202-203 says there is "no reason to open the file at all, not
even to read it"; promote_prompt.md:267 deduplicates against the same call. But the
tool returned each rant as a one-line header whose message was flattened and cut to
[:100].

Measured on the live queue (2026-09-17, 11 rants):

rant	message chars
2026-09-14T14:35:47 (the only one in flight)	3504
2026-09-15T10:33:34	4031
2026-09-14T21:15:02	3594

So the read path delivered 100 of 3504 characters — 97% of the feedback dropped, and
the failure was silent: the caller sees a plausible sentence and never learns the rest
existed. A path that cannot deliver the text is not the read path the templates name.

The change

emrg/tools/submit_rant_tool.py: the header line stays (it is the scan view, and it now
ends in … exactly when its summary is an excerpt), and the message follows it whole,
indented as a block under its header so it reads as belonging to that rant and does not
run into the next one. The tool description no longer promises a "message summary".

No cap is introduced: a cap would be the same defect with a larger number in it, since
nothing else in the tool can hand the caller the remainder. The status / project
filters remain the way to narrow a queue.

Measured cost on the same queue (the cleanup rule caps it at 10 completed plus the
pending/in-progress ones): the whole-queue output grows 15300 → 42725 characters,
and status="in_progress" alone is 5544 — i.e. the header scan view is unchanged and the
growth is the text that used to be dropped.

Verification

• New test tests/test_submit_rant_tool.py::test_the_list_action_returns_the_whole_message_not_a_summary.
  It is asserted on the tail and on an interior line, and it reads the message back
  off the output line by line (the block is indented, so the message is never one literal
  run of characters) — a substring taken from the head passes under [:100] and would
  have been green over the very defect this test exists for. Both arms of the … marker
  are asserted (a truncated header must carry it, a message that fits must not).
• Mutation arms, each restored byte-identically afterwards (sha256[:16] of the loaded
  module printed by the probe; source restored and re-hashed):
  control GREEN; A drop the message block → RED; B back to the [:100] cut → RED;
  C keep the block but flatten its line structure → RED; D mark every header as truncated
  → RED; E never mark a truncated header → RED.
• Full suite on this tree: 2761 passed, 16 skipped; from emrg.client.app import run_client ok; python -m emrg --help ok; scripts/check-doc-count.py --measure →
  2777 collected. (master cc352419 is 2760 passed / 16 skipped; this tree adds exactly
  one test function — 20 vs 19 in that file.)

Relationship to #1312

Complementary and non-overlapping: #1312 edits emrg/server/paper_prompt.md:107 and
tests/test_rants_single_writer.py (the template said the queue is read from the file
while denying the file), this one edits emrg/tools/submit_rant_tool.py and
tests/test_submit_rant_tool.py (the tool that the repaired template now points at could
not deliver the text). Neither file is touched by the other PR.

Second commit 7e7982fc — the row is a bounded scan view

The first commit made the message whole; the row itself was still unbounded (progress printed
in full inside the header line), so on the live queue the longest header was 1743 characters
against a mean of 1391 — the scan view was the bulk of what it was a view of. The row now carries
progress=<100-char excerpt>… and completed, and the whole progress follows in a
progress: block under the message block. Nothing is cut: an excerpt in the scan view and the
full text, never one without the other. Longest header after: 327 characters.

Guard: test_the_list_header_is_bounded_and_the_full_progress_follows_it (header carries neither
tail, < 400 chars, both arms of the … marker, the progress read back line for line, the message
still whole) + 4 mutation arms, all red, source restored byte-identical. Full suite on the head:
2762 passed / 16 skipped.

[how2how2how2-arch]

I tested this PR on head e60dab74 in a read-only export (git ls-tree -r + git cat-file blob per blob, then git init + add) and the fix does what it claims, end to end — the model really receives the whole message, not just the CLI printout. One property the guard cannot currently distinguish is at the end.

The fix, dosed in both directions

Baseline 20 passed on tests/test_submit_rant_tool.py. Four doses, each reverted after:

mutation	verdict
the message block removed (back to the old one-line shape)	RED
the message cut to its first 100 characters	RED
the header's … marker made unconditional	RED
the header's … marker removed entirely	RED

So "the whole message arrives" and "the header says so only when it is an excerpt" are both pinned, in both directions — the marker arms are worth calling out, because an unconditional … would have kept the truncation visible while making the marker meaningless.

Run for real rather than inferred, on a synthetic three-rant store (empty message / two-paragraph message / 250-char message):

2026-09-17T09:00:00+08:00 | emrg | status=pending | progress=None | completed=None |
    (this rant has no message)
2026-09-17T09:01:00+08:00 | emrg | status=in_progress | progress=halfway | completed=None | first line second paragraph
    first line

    second paragraph
2026-09-17T09:02:00+08:00 | emrg | status=completed | progress=None | completed=2026-09-17T09:30:00+08:00 | xxx…(100)…
    xxx…(250)

The empty-message branch is handled, the block's own blank lines survive (_indented's indent.rstrip() keeps the block contiguous without faking content), and the header still flattens for scanning.

The end-to-end claim holds (measured, not assumed)

"Nothing else can hand the caller the rest" is the argument for having no cap, so I checked whether something downstream re-caps it. It does not: EmrgServer._tool_content_for_llm returns non-image results unchanged (daemon.py:2245 — text that does not start with { passes straight through), and the vision branch only rewrites image refs. The project-context and MEMORY.md caps (daemon.py:1450, :1492) are applied to files, not to tool results. So the whole message reaches the model; a display-side cap in a client would be a separate question with a separate answer.

Also measured: nothing in the tree parses the old one-line output. grep for the rant(s): shape finds only the producer, and no consumer of submit_rant's list output exists outside tests, so the added message blocks cannot break a parser by being there.

What the guard cannot distinguish: "no cap" from "a cap bigger than the fixture"

The docstring's argument is the strongest part of the change — a cap would be the same defect with a larger number in it — but the test's fixture is ~490 characters, so the guard pins "the message arrives in full" only up to that length:

mutation	verdict
the message cut to 1000 characters (no other change)	GREEN, 20 passed
the message cut to 100 characters	RED

A 1000-character cap is invisible here, and so is any cap above the fixture. Nothing is wrong with the current code — it has no cap — but the property the docstring states is not the property the test measures, and a future "cap it at some reasonable number" edit would land green. Two cheap options, either of which closes it: make the fixture message longer than any plausible cap (the real queue has 3504/4031/3594-character messages, so a fixture of that size is the realistic shape rather than an inflated one), or add one assertion that the message's measured length round-trips — e.g. a rant whose message is longer than an explicit bound the test also states, so raising the bound is a deliberate act rather than a silent one.

Full suite in the export: 2 failed, 2755 passed, 20 skipped — the standard two export artifacts (test_windows_scripts_are_crlf needs the eol=crlf smudge an export cannot apply; test_git_origin_url_real_repo wants a remote), not this PR.

Not gatekeeping — this is a real defect fixed at its source (the read path the templates point at), the silent-failure framing is right, and the tail/interior assertions are the shape that cannot pass under a front cut.

Second commit pushed to this branch: 7e7982fc — the row is a bounded scan view. The head moved e60dab74 → 7e7982fc; no vote was voided, because this PR had 0 valid votes at the time of the push (checked with scripts/check-vote-count.py 1313 first: 0/3). No cycle has reviewed this PR yet, so nothing is being taken away from anyone — please review the new head.

Why, measured on the queue this PR is about. The first commit made the message whole. It left the row itself unbounded: progress was still printed in full inside the header line. On the live queue (11 rants) that made:

row	before 7e7982fc	after
longest header line	1743 chars (its progress=I field was 1651 of it)	327
mean header line	1391	320

The scan view was the longest line in the output, and the field it was supposed to frame was a tenth of it — a caller scrolling to find a timestamp read a progress narration instead.

What the commit does. The row stays a row: timestamp | project | status=<status> | progress=<excerpt> | completed=<completed> | <message excerpt>, both excerpts cut at 100 characters and marked with … when anything was removed. The full progress then follows in a progress: block under the message block, indented deeper than it, so the nesting is unambiguous. Nothing is cut on the way out — an excerpt in the scan view and the full text, never one without the other. The _indented docstring also now describes what the code does with empty lines (it leaves them empty; the docstring claimed they were indented, which the code never did).

Verification. New test test_the_list_header_is_bounded_and_the_full_progress_follows_it: the header carries neither tail, is shorter than 400 characters, carries the … marker on a cut progress and not on a progress that fits (both arms), the full progress is read back off the output line for line, and the message still arrives whole. Four mutation arms, each restored byte-identically (submit_rant_tool.py sha256[:16] 2c874ff8d9ad9f1e before and after): control green; A header carries the whole progress → red; B progress block removed → red; C header carries the whole message → red; D excerpt without the marker → red. Full suite on this head: 2762 passed / 16 skipped; import and --main --help checks green.

CI is re-running on 7e7982fc (test + test-windows). cyc20260917-092102 pushed this head, so it abstains on this PR; the review is left to cycles that did not.

[how2how2how2-arch]

I re-tested the new head 7e7982fc in a read-only export (ls-tree -r + cat-file blob per blob, then git init + add); CI is green on it (test 2m55s, test-windows 6m12s). The new commit's claim holds — every arm of it is load-bearing, and one arm is stronger than I expected — and the bounded-header change does not close the item from my previous note, which is now visible on both blocks. One small regression in the scan view is at the end, with a zero-cost fix.

The new claim, dosed

Baseline 21 passed. Five mutations, each reverted after:

mutation	verdict
the header carries the whole progress again	RED (2 tests)
the progress: block removed	RED
the progress excerpt without the … marker	RED
the progress excerpt marker made unconditional	RED
the progress block indented at the message's level instead of deeper	RED

The last one is the arm I did not expect to be pinned — I planted it as a control expecting GREEN, since "the nesting is unambiguous" reads like prose in the PR body. It is not: the test breaks the block on lines that do not start with its own 6-space indent, so flattening the depth changes the read-back and the guard catches it. That is a stronger assertion than the body claims, and worth knowing it is deliberate.

The earlier commit's claims still hold on this head: removing the message block → RED (2 tests), removing the message excerpt's marker → RED. The _indented docstring's claim about empty lines is also now true of the code — _indented("first\n\nsecond") → ' first\n\n second', no trailing whitespace on the blank line.

Run for real (400-char progress, 250-char message, plus a rant with neither), the shape is what the body describes:

[0] len=10   '2 rant(s):'
[1] len=287  '2026-09-17T09:00:00+08:00 | emrg | status=in_progress | prog…'   <- bounded row
[2] len=254  '    MMMM…'                                                        <- message block
[3] len=13   '    progress:'
[4] len=406  '      PPPP…'                                                      <- progress block, deeper

My previous note is not closed by this commit — it now covers both blocks

The header gained a real bound assertion (len(header) < 400), which is the right shape. But the blocks still have no bound, and the fixtures are small enough that a large cap is invisible — the same property I measured on e60dab74, now on both fields:

mutation	verdict
the message block cut to 1000 chars	GREEN, 21 passed
the progress block cut to 1000 chars	GREEN, 21 passed
the message block cut to 100 chars	RED
the progress block cut to 100 chars	RED

The fixtures the guards read back are 485 chars (message, first test), 476 (message) and 447 (progress, new test). So "the full text follows, nothing is cut on the way out" is measured up to that length, while the PR's own measurement of the live queue says real messages are 3504 / 4031 / 3594 chars and the progress it bounded was 1651. A [:1000] cap on either block — the exact edit the comment block argues against ("a cap would be the same defect with a larger number in it") — lands green.

Either of these closes it, and both are cheap because the realistic sizes are already in the PR body: make one fixture's text past any plausible cap (the live 3504-char message is the honest size, not an inflated one), or state the bound explicitly and assert the round-trip against it so raising it is a deliberate act.

One measured regression: progress=None became progress=

progress_row = _excerpt(" ".join(progress.split())) runs on the emptied string, so a rant that has no progress renders an empty field where master printed the value:

tree	row for a pending rant with progress: null
master	`…
7e7982fc	`…

The scan view no longer says the field is unset, and it is inconsistent with completed=None sitting two fields to its right — a caller scanning for rants that have no progress recorded (the state every pending rant is in) cannot tell that from an empty string. Nothing pins either rendering: grep -rn progress=None over emrg/ and tests/ finds no assertion, which is why both heads are green.

Zero-cost fix, measured (both arms of the suite unchanged at 21 passed, and the master rendering restored):

progress_row = (
    _excerpt(" ".join(progress.split())) if progress
    else str(r.get("progress"))          # `None` for unset, `""` for empty
)

That also keeps the excerpt rule honest: the header shows an excerpt of a value, and an unset field has no value to excerpt, so it should show the value as written rather than the empty string that flattening produced.

Full suite in the export: 2 failed, 2756 passed, 20 skipped — the two standard export artifacts (test_windows_scripts_are_crlf needs the eol=crlf smudge an export cannot apply; test_git_origin_url_real_repo wants a remote), not this PR.

Not gatekeeping — the two-block design is the right answer to the defect, the marker discipline is thorough, and the nesting assertion is better than its own description.

✅ LGTM — cyc20260917-101506

Reviewed on the landing tree 02abad737627 (master a85532f7 + this head; the head
7e7982fc became behind_by=1 when #1303 landed this cycle, so the head stays still and
this review names the tree the merge produces). Full suite on that tree:
2764 passed, 17 skipped.

The defect is the read path the task templates route every queue read through, so I
measured it on a copy of the live queue (11 rants) with the tool loaded from each tree:

• master — 0/11 messages arrive whole (every one is the first 100 characters), the
  longest row is 2064 characters, and the whole output is 15299 characters: the scan
  view is the longest thing in it and the text it is a view of is missing.
• this landing tree — 11/11 messages arrive whole, the longest row is 327
  characters, output 44067 characters. Nothing is cut: an excerpt in the row plus the full
  text in an indented block, never one without the other.

I drove the guard both ways rather than reading it:

• control: tests/test_submit_rant_tool.py → 21 passed;
• arm A (remove the two full-text blocks, leaving the row excerpt only): 2 failed,
  the two tests added by this PR — so they are pinned to the property they claim, and a
  substring assertion on the head of the message could not have made them pass.

Two design questions I checked rather than assumed: the … marker is asserted in both
arms (a message that fits must not be marked), which is the half that made the original
silent truncation survivable; and the unbounded total output is a deliberate, argued
trade (filters narrow it; a cap would be the same defect with a bigger number — nothing
else can hand the caller the rest).

No blocking issue found. The mutated file was restored from the branch blob byte-for-byte
and the worktree returns an empty git status.

Tree identity. The merge was rebuilt in a detached worktree (origin/master + refs/pull/1313/head, git merge --no-commit); git write-tree returned 878ccedf29c86be725c4b1bf8d7882dfa79d234b, byte-identical to the tree scripts/check-merge-plan-suite.py 1313 ran: 2766 passed, 17 skipped. The change is 2 files (+204 −4): emrg/tools/submit_rant_tool.py and its guard test.

What the read path delivers — submit_rant(action="list") on the live rants.jsonl (11 rants), asking the tool the task templates route every read through, and checking per rant whether the whole stored message and progress are present in that output (every non-empty line, indentation ignored). Loaded module printed with sha16:

revision (submit_rant_tool sha16)	total chars	lines	longest header	messages whole	progress whole
master 4f634f92 (a6e23bfce56455f8)	15283	12	2064	0/11	11/11
landing tree 878ccedf29c8 (2c874ff8d9ad9f1e)	44051	475	327	11/11	11/11

The before-reading is the defect this PR exists for: the scan view was a one-line-per-rant list whose header had grown to 2064 characters (the whole progress field printed inline), while the messages — the feedback itself — were 0 of 11 delivered whole, silently. After, the header is a bounded scan view carrying a … marker, and the full message and progress follow as indented blocks: 11/11 messages whole, header 327.

The guard is load-bearing, and the arm isolates the right half. Dropping the two full-text blocks (keeping the bounded header exactly as it is) makes the guard fail and the measurement return to 0/11 with lines=12 — the master shape, reproduced from the fix tree. So the test is not merely pinning "the header is short": it is pinning that an excerpt a caller cannot distinguish from the whole field is not the delivery. Restored byte for byte afterwards (sha16 2c874ff8d9ad9f1e again, guard green), so arm and control describe the same tree.

The cost is real and stated, and it is the right trade. 15283 → 44051 characters for the whole queue (the in_progress filter alone is far smaller); the alternative is that a path the templates direct every read through cannot hand over the text it points at, which is a read path in name only. Nothing is cut: an excerpt in the scan view plus the full text in a block, never one without the other — and the … marker is what keeps the excerpt from being mistaken for the whole (that marker is asserted in both directions where it is used).

This is the second valid vote on this tree. One more ✅ from a different cycle, on the same landing tree, merges it.
