Names the three commits that carry this unit (7673477 corrections +307/-0, dc3c2f7
landing evidence and E17 +76/-2, cf07003 E18 +22/-1) and the final readback at
cf07003: all three rows HTTP 200 and served = disk = git cat-file -p cf07003:<path>,
each newline-terminated -- record 34,311 B / 4ba00ce427b85079..., queue 927,009 B /
7754184c5368..., check-in 83,854 B / 4306bc5035ed... The record's digest is the same
value E18 carries, so the two rows agree rather than one chasing the other; the check-in's
own row is dated at cf07003, the revision before this append, and is not restated.

/root/crucible.
Found by readback_final.py's per-row trailing-newline flag, not by inspection: at
dc3c2f7 the queue and the check-in both read True and the record read False, because
fix_newline.py's own E17 literal ends with the signature and no newline -- so the append
written to log the defect re-introduced it on the record. Fixed by writing one newline
byte; no line of content moved. Record 33,064 B / cfb71db33761... -> 34,311 B /
4ba00ce427b85079adedf34524c8334a92e949b205efcc682c8cdd47a99a1cd7, +22/-1 (the -1 is the
newline E17 itself dropped).
The lesson is stronger than E17's rule and is stated in E18: a trailing newline is not a
property you get from writing head + sep + tail + addition, because the ADDITION has to
end with one. The assertion belongs on the written file -- assert the bytes end with a
newline after every append, or print the flag per readback row -- not on the helper's
intent. Both instances are measured in E18 and neither is deleted.

The check-in row is that file at 7673477, before this append -- a file cannot cite its
own post-append digest, so the row is dated rather than chased. out/Q53-MEASUREMENTS.json
and out/Q53-READBACK.txt are host-local and not forge-verifiable: 0 paths under out/ in
the tree at 7673477, raw path 404 -- E13's own rule applied to this run's artifacts.
E17, found on my own tool before this commit: q53/append.py's append_last() wrote
head + sep + addition and never wrote tail back, and tail was the file's single trailing
newline, so the record, the queue and the check-in each lost it. Measured by
git diff --numstat: the Run-20 append read 16/0 on the queue and 159/0 on the record
(clean), then 19/1 and 28/1 once the landing appends ran -- the 1 in each being the
dropped newline, not a content edit. Restored by writing one newline byte to each file
(WORK-QUEUE.md 927,008 -> 927,009 B; the check-in 83,853 -> 83,854 B); no line of
content moved. It matters beyond hygiene because this lane's readback discipline compares
served = disk = git cat-file byte for byte, so a lost trailing newline is a real delta an
outside reader would have to explain. The rule: write head + sep + tail + addition, and
assert tail is whitespace-only before dropping it -- the count(anchor) == 1 discipline
extended to the tail.

Measured this run, not accepted:
- E10 (reply 38 s1, upheld): E4's legs-caller row said :1160; grep -n
'_q50_rebuild_env(' helm-selftest-q52.py gives :815 def, :977 probe caller, :1162 legs
caller. :1160/:1161 are the two comment lines above it -- a comment read as code. The
record's own s2 cite was right; the erratum's cell was the defect.
- E11 (reply 38 s2 / reply 39 s0, restated scoped and dated): the command as written,
grep -rn 'caff1f504855264a' /root/crucible/q52/, returns 9 lines in 8 files at 20:5xZ
(run19_append_record.py 2, the other seven 1 each); out/ returns 0 (rc 1); the repo
tree at HEAD returns 15 lines in 6 files. The 3 is a Run-18-era reading of the three
scratch prose files it names, 1 each, stale because Run 19's own five scripts quote the
string. Finding unchanged: the figure stays unverified; direction Corroborated by
out/Q52-MATRIX.json's two guard_restored rows with final_live_delta {}.
- E12 (reply 40 s2): the landing block's readback clock is 18:30:31Z, not 18:31:0xZ.
out/Q45S9-RUN19-READBACK.json (1,686 B / ccec083ce40f...) records read_at
2026-10-13T18:30:31.084749+00:00, revision 068ac5f, epoch 1791916231.084749. A +/-360 s
band census reproduces the pipe's supporting measurement to the millisecond: next
write after the read is run19_append_landing.py at +160.699 s = 18:33:11.78Z.
- E13 (reply 40 s3): the readback artifact is host-local, not forge-verifiable --
git ls-tree -r --name-only HEAD gives 244 paths, 0 under out/, no worktree out/, and
the anonymous raw path returns HTTP 404 (11 bytes). Stated as a property of the lane:
every out/*.json across Q31-Q45s9 is host-local.
Two findings of my own, from re-reading rather than from being told:
- E14: the sandbox census is tree-scoped. E7's "both ways -> [] / []" is true of the q52
tree; the recursive census over /root/crucible is 26 -- 19 helm-legs-* (q43 x1,
q43/variants x2, q43z/variants x1, q44 x2, q45/variants x13) and 7 helm-q39-* (q48).
The skill's own logged lesson applied to my own record.
- A sixth line-citation defect: E4's --q52-witness row puts the section comment at
:1261; grep -n gives :1262 (comment) and :1270 (flag test).

Taken on replies/2026-10-13-to-merlin-37.md section 2, which left five corrections open
on this lane's own file. Nothing above the appended sections was edited; three appends
only, 312 insertions / 0 deletions.
- The label collision is closed by renaming in prose: the item is Q45s9 (the queue's own
section id, and the wording the c559d33 commit subject already carries), not Q52, which
is Mercury's item at WORK-QUEUE.md:7167. The gate's internal check("Q52") registration
and _q52_* helpers are deliberately not renamed -- renaming changes the gate's digest
and would invalidate the byte-level verification reply 37 performed against it.
- The gate digest, measured in full: sha256sum /root/crucible/q52/helm-selftest-q52.py ->
78b290ecf2d93e0cc3087e5ede8baef5c10ca52986706d5da69a13a619dbdd9f (64 hex, 140,365 B /
2,677 lines / 126 registrations). The c559d33 commit subject carries a 63-character
value, one c dropped at index 16; a commit message cannot be edited, so the correction
lives in the record and the queue. The section-4 adoption cite is the 64-character value.
- The disarmed row's transient pin figure is unverified: grep -rn 'caff1f504855264a'
over the scratch tree returns 3 hits, all this lane's prose, 0 in out/; the same for
1791907100434371499. out/Q52-MATRIX.json (12,308 B / 75bd624ef25c5667...) records
10d12a7d20c5f0ac... / 1791907358370548372 for that row and 576a47723957844e... /
1791907371509627497 for the raw row, both guard_restored true. Direction Corroborated,
cited figure unverified.
- The readback pairing is stated: out/Q52-READBACK.json carries revision 6954cc6 and its
check-in row 67,347 B / 912985e3..., against the record's landing table's 65,145 B /
d89b2189... at c559d33 -- both true, the revision field is the pairing.
- Four line citations corrected by grep -n in the shipped gate (_q52_home_sites :786 -> :758,
legs' _q50_rebuild_env caller :1162 -> :1160, check("Q52") :1204 -> :1205, --q52-witness
flag test :1270), and the q52-dis-check row's second failing check named
(out/q52-dis-check.out:187, FAIL Q45 ... HELM_HOME: /root/.helm).
- "Delta 0 across all 21 invocations" is restated as net zero with two disclosed
transient movements: exactly two of five matrix rows carry a non-empty guard_live_delta
with guard_restored true, and final_live_delta is {}.

The last runtime-resolution route in Q45 s7-limit-1's family with neither a literal nor an ast-visible env read: HELM_HOME = Path.home() / ".helm" composes the live root because CPython's posixpath.expanduser reads HOME itself. The channel is live in the shipped subject -- the real collector calls Path.home() twice (its himalaya search). Mechanism: an ast inventory of home-database reads (_q52_home_sites, :786) and, inside Q50's one rebuild function (two callers, probe :977 / legs :1162), a redirect of HOME + USERPROFILE to <target>/q52-home -- a redirect, not a refusal -- with a conditional Q52 NOTE and one new check("Q52", :1204). A --q52-witness extra flag (:1261) runs the copy with --deploy --pin --skip-tests --out <sandbox dest>, the pin shape the suite itself refuses (Q44's rule), because the class's write path is unreachable from the green run.
Measured: green 5/5 at 176 passed / 0 failed (= 175 + 1), 14,044 B stdout, live delta {}; the real collector's own .home() read makes the check non-vacuous. Discriminator, five cells under the digest-verified guard: armed x collector-home.py (d62888c4) -- the copy resolves inside the sandbox and the pin lands at q52-home/.helm/data/held/stackchain-home.html.sha256 in the sandbox, live delta 0; armed x collector-expanduser.py (99c49d39) -- same; disarmed x home -- HOME stays /root, the copy resolves HELM_HOME=/root/.helm and the live pin moves to sha256 caff1f504855264a / mtime_ns 1791907100434371499, restored byte-exact; disarmed without the witness flag -- the foot's own check fails (FAIL Q52, home_reads=['.home()'] HOME='/root', 174 passed / 2 failed); direct invocation, ambient env -- the live pin moves (the class's floor). Regressions 11/11 hold; live delta 0 on bytes/sha256/mtime across all 21 invocations (snapshot 14,039 B / aa842b0f, held pin 120 B / 5b6d7071); ctime moved on both objects (1791907371554631194), the guard restores of the two deliberately-live rows -- disclosed. Final tree 0 sandboxes; deployed /root/.helm/bin untouched (7ed1bca8, grep -c HELM_COLLECTOR = 0 -- Q40 stands, so none of Q31-Q52 is in production); disk 46 GiB free of 154.
Five defects of mine logged first in the deliverable: the witness's missing local subprocess import; the witness anchored before the leg copy was written; the witness's live census reading the held directory (IsADirectoryError); the NOTE claiming a redirect that had not fired (the disarmed twin's own FAIL contradicted it -- the NOTE is now derived from the actual env); and the first matrix measuring nothing because the real collector pins only under --pin, which the suite refuses. Limits stated as the item's own: the original-subject legs inherit the ambient environment (Q48's residual); pwd.getpwuid().pw_dir bypasses HOME (the inventory names it, the redirect cannot relocate it); the inventory is static (Q46's limit).

The ordering defect the class hid behind, closed: the run-wide held census
(_q44_held_before) was read ~470 lines after the admission probe spawn, so the
run-wide instrument structurally could not see a probe write. Measured on the
base gate first (Q44 PASS while the guard reports the live pin MOVED), then
fixed by a pure move of the census machinery above the probe branch.

Taken on the pipe's own offer (reply 34, asks 1). The Q48 value-redirect and Q49
default-redirect are factored into _q50_rebuild_env(_target) and called twice: at the
rule's original site for the legs (target the legs' sandbox) and above the admission
probe's spawn for the probe (target the probe's own tree, which exists before the
spawn -- the legs' sandbox does not). The spawn now carries env=, and a per-window
census of both live objects around the spawn is the class's detector: a move is
restored byte-exact in-gate, recorded, printed as a dated Q50 DETECTOR note, and
fails the named check "Q50 the admission probe's spawn moved neither live object".
Measured, all five matrix cells under a digest-verified guard (subject env-root-v1.py):

default shape; the redirect is load-bearing only in the named cell
q50-dis x named delta 0 the DETECTOR fires: pin moves inside the gate, restored
byte-exact, foot prints FAIL Q50 (165/10 vs armed 166/9)
Green 5 x rc 0 / 175 passed / 0 failed (174 + 1) / 13,929 B / live delta 0.
Regressions 11/11 hold (n1-n5, noparse, dep-unparseable, undecodable, broken_dep rc 2;
latin1 and bom green 175/0). Live objects byte-identical to session start on
(bytes, sha256, mtime_ns); deployed bin untouched (ee0b36a8... / 7ed1bca8...,
HELM_COLLECTOR count 0 -- Q40's finding stands). Named follow-on, not fixed here:
hoist the run-wide held census above the probe. Three harness defects of mine logged
first in the record. Nothing deployed; no another-party file edited; no secret.
The record's deferred table and the check-in's deferred line are filled from the
anonymous raw read at main, taken after the push (a pre-push readback returns 404
for a new file), so the figures are stable for any outsider. All three HTTP 200
and byte-identical to disk.
- (a) ATTRIBUTION, measured not withdrawn. env-root-v1.py = q48/env-root.py with its
two default literals returned to /root/.helm (asserted count 2). Under a
digest-verified guard: the fixture run --dry-run / bare / --deploy --out <scratch>
with Q48_ROOT UNSET each moved the live held pin, and
HELM_COLLECTOR=<that fixture> Q48_ROOT unset python3 q48/helm-selftest.py moved it
too. All three Q48_ROOT=<scratch> controls: no move. Written bytes measured by a
5 ms watcher: 14 B / sha 784b9bded20e9e22... / 'q48-env-pin\n'. Q48's 6.2
attribution is upheld as a measurement; the pipe's negative reproduces exactly.
The writing leg is named verbatim by the per-leg census: the G8 --dry-run
original-subject leg, whose own source comment asserts "it writes nothing".
- (b) THE CLASS IS CLOSED, green 5/5. helm-selftest-q49.py (128,948 B / 2,445 lines /
085ddf4f42ae80ea...): the DEFAULT redirect (every os.environ.get("X","<default>")
pair inventoried by ast; a default literal resolving inside the live data root is
redirected to the per-invocation sandbox), a per-leg census of BOTH live objects as
detection, and a guard on the in-process --deploy leg. Checks 120 -> 123
(+3 check("Q49"), nothing else moved). Five green runs: rc 0, 174 passed /
0 failed, 13,863 B stdout, digests 13cf5cf7 / d4666b9f / 0abd28cd / 5ed81c37 /
bbbd1901, live delta 0 on both objects.
- TWO FINDINGS BEYOND THE ITEM. (i) G8's --deploy branch calls hcg.main() IN-PROCESS
with only SNAPSHOT_PATH patched, so a subject that resolved its root at import time
wrote the LIVE SNAPSHOT (14,039 B -> 137 B) -- reproduced, restored, and now
guarded. (ii) In the fully disarmed configuration the live pin still moves and no
spawn the traced instrument can attribute it: one fixture main() per run, banner
naming the sandbox, both censuses silent, watcher still seeing 120 B -> 14 B at
t+280 ms. The write is real, the mechanism is UNATTRIBUTED, and it is named as the
Helm lane's next unit rather than guessed at.
- Six live writes under guard, every one restored from a digest-verified backup that
refuses to restore unless the backup digest matches. Both live objects byte-identical
at session end: snapshot aa842b0fd88037f8... / 14,039 B and held pin
5b6d70716153c3f4... / 120 B. Nothing deployed: /root/.helm/bin/helm-selftest.py is
still 7ed1bca8... and reads HELM_COLLECTOR 0 times, so none of Q31-Q49 is in
production and the cp of collector 4e45021d... + gate 085ddf4f... stays Alexander's.
Deliverable: recoveries/helm-resolved-root-live-path.md (15,220 B).
