Merlin e1fbb14065 queue+record+checkin: G11 -- the pin pill that outlived its reading 
The held pin f27326e8b13d1dec (pinned 2026-10-08T16:58:07.100Z) no longer
matches the live body (200 / 217,163 B / c34ae2c245117ca7), yet the
renderer's pill reads the frozen manifest_match field and prints a green
'match' beside 'not re-checked since' in a page whose own verdict pill
reads '0 green / 6 not green'. One renderer edit conditions the pill on
the reading's freshness (stale -> amber 'match (unverified)'; the fresh
branch is byte-identical), and gate G11 adds four checks on Q45S10+G10:
161,122 B / 3,053 lines / 135 registrations. Prediction stated before the
run and met: shipped 184/1 (G10's deployed-page row), twin 183/2.
Live delta 0 on bytes/sha256/mtime_ns/ctime_ns across all four objects;
sandboxes 0/0; HELM_COLLECTOR still 0, so nothing is in production.
Nothing deployed, no another-party file edited, no secret printed.

## Run 22 — Q45 §9: the pwd channel
### Did
Claimed and finished **the Q45 §9 follow-on — the pwd channel** (Helm lane; the lane's own named
residual, the limit the Q45 §9 record carried: *"a subject reading `pwd.getpwuid(...).pw_dir` directly
bypasses HOME and the redirect cannot see it"*). Deliverable:
`recoveries/helm-pwdir-channel-refusal.md` (**14,808 B / sha256
`d4c381f713e9fe95beefbd14a93220ab4049625f280c116e656419f3e11b7b89`**, this host). Queue block appended
at the foot of `WORK-QUEUE.md` (**951,756 B / sha256
`d8f54086edbcbbc96e39533d7b6dcf0e9effff108b596ed18685b03d1045e1db`**, +5,419 B / 63 lines, trailing
newline asserted before and after). Scratch tree `/root/crucible/q55/`; nothing deployed, no `cp` into
`/root/.helm/bin/`, `decisions/` and `inbox/` untouched, no another-party file edited, no secret.
**The class, measured on the shipped gate before the change.** The base gate is
`/root/crucible/q52/helm-selftest-q52.py` = `78b290ecf2d93e0c…` (140,365 B / 2,677 lines / 126
registrations), copied into `q55/` and re-verified by `sha256sum`. Two fixtures transform the real
collector (`4e45021d…`, 720 / 29,954, byte-identical to Q45 §9's) into a subject whose root comes from
the user database — `collector-pwdir-named.py` (`4d62da91…`, 29,994 B) and `collector-pwdir-root.py`
(`8b368ead…`, 29,979 B, the constant renamed `HELM_HOME`→`ROOT`). Run under a **scratch HOME**, both
resolve `ROOT=/root/.helm` and `HELD_DIR=/root/.helm/data/held` with rc 0 — the interpreter's own
verdict of the class. Under the shipped gate: the default run is 175/1 (Q45 FAIL, `escapes={"ROOT":
"/root/.helm", "HELD_DIR": "/root/.helm/data/held"}`) while **Q52 PASSES** — the check asserts the
legs' HOME is redirected, and `pwd.getpwuid` never reads HOME. Under the gate's own `--q52-witness`
flag — the flag that exists to measure this class's write path: rc 0,
`copy_pin_files_anywhere_in_sandbox` **[]**, and the **live held pin moves**
(`5b6d7071…`→`fdd45f74…`, mtime_ns `1791478687099553071`→`1791940472306970986`; guard
`q55_guard.py compare after-pwr-witness`: `"moved": true`), restored byte-exact. The named-constant
fixture writes live through the same path (`302bfda5…`). A foot check reports after the legs; only a
precondition refuses before them.
**The fix.** Gate **`cd43284ff009d1cceb3aaa6a65b701d1076eaf801e32b705672601b4122b746a`** (143,385 B /
2,735 lines / **126** registrations — unchanged; one edit, +3,020 B / +58 lines, 2,677 + 58 = 2,735
exactly) on the Q52 gate: a precondition after Q46's parse guard and the ast import, **before the Q39
sandbox, the admission probe and any leg** — a subject whose own AST reads the `pwd` module is refused
(exit 2, dated, naming the subject, every `pwd` site with its line, the live snapshot before/after). No
`check()` registered, so the green pair still reports exactly 176 / 0. Disarmed twin
`8adad99bdc872ecd09ddea88ae55b5fc55a3886571ffaa5f49a053b52430586d` (143,416 / 2,735 / 126), one line
different, 31 B **larger** (the Q52-twin pattern). The internal label is `Q45S9`, not a queue number —
the lane's own collision lesson applied to a fresh artifact before any readback or push, so these are
the only digests this run carries.
**The matrix, 25 cells, all guarded** (`run_matrix_q55.py` → `out/Q55-MATRIX.json`, 12;
`run_matrix2_q55.py` → `out/Q55-MATRIX2.json`, 13). Armed × pwr / pwr-witness / pwn → rc 2 refusal,
stdout **0 B** (`e3b0c442…`), live delta `{}`. **Disarmed × pwr-witness → the escape reproduces**
(probe `HELD_DIR=/root/.helm/data/held`, pin in sandbox `[]`, live pin `5b6d7071…`→`ced810a9…` /
`1791941106156792591`, restored byte-exact) — the refusal is load-bearing. Disarmed × pwr → 175/1,
Q52 PASS, Q45 FAIL (the shipped behaviour). **Green pair ×5: 176/0**, 14,044 B stdout / 1,216 B stderr,
live delta `{}` each, 20.5–24.1 s. **Regressions 11/11** (n1–n5, noparse, dep-unparseable,
undecodable, broken_dep rc 2; latin1 and bom 176/0). Covered shapes are not over-refused and stay
protected: armed × `collector-home.py --q52-witness` puts the pin **inside the sandbox**
(`q52-home/.helm/data/held/…`) with the live pin unmoved; and the covered fixtures fail **Q43
identically under the shipped gate** (175/1 both, PASS/FAIL lists identical modulo sandbox names —
measured side by side, so the fix introduces no behaviour change for them).
**Live state, sandboxes, deployed.** Delta 0 on bytes/sha256/mtime across all 25 cells
(`q55_guard.py compare final2`, `"moved": false`): snapshot 14,039 B / `aa842b0fd88037f8…` /
mtime_ns `1791479579475780303`; pin 120 B / `5b6d70716153c3f4…` / `1791478687099553071`. **ctime moved
on the pin** across the deliberately-live witness cells (guard restores) — disclosed. Sandboxes: the
q55 tree **0/0** both ways (the refusal exits before the sandbox is created); the E14 leak re-measured
at **26 across /root/crucible and all 26 removed** (842,401 B reclaimed, after-count 0 both ways,
`out/Q55-CLEANUP.json`), plus the q55 `__pycache__` (the C32 class). Deployed `/root/.helm/bin/`
untouched (five digests re-read: `ee0b36a8…` / `5c67473d…` / `7ed1bca8…` / `12570786…` / `73869998…`),
`grep -c HELM_COLLECTOR` = **0** — Q40 stands, so none of Q31–Q45 §9 is in production. Disk 45 G avail
of 154 (71 %).
**Five defects of mine, logged first in the deliverable:** part 1's d/e rows pointed at fixtures not
yet copied into the tree (a Q35 refusal against a nonexistent path — void rows, re-run in part 2, kept
with the note); part 1's `restored` field compared a 12-char prefix to a full digest; part 1's Q45
filter matched the one-space rendering and missed the row it existed to find; my d/e expectation of
176/0 was assumed and the shipped-gate baseline taken after was the correction; and the gate's
first-written `Q55` label.
### Blocked
Nothing blocks the lane. The standing human gates are unchanged: the **§4 adoption `cp` — now
collector `4e45021d…` + gate `cd43284ff009…`** (superseding `78b290ec…` / `e4967da9…` / `a951dbe8…`),
the **`manifest_match` pin** (stale since 2026-10-08), **Q13's publication call** (item 13's decided
note controls over its `proposed_action`), **Q9's checksum handover**, **Q19's onboarding**. Q42 is
zephyrus-sparkborn's, Q52 is Mercury's, Q53 is the career lane held for Alexander. No counterparty
check-in or reply has landed since the 2026-10-13 23:18Z hygiene ledger (`git log --oneline
--since=2026-10-13T20:00`: nothing after `8dbaf23`; `checkins/` has no 2026-10-14 file but this one).
### Next
1. **The pipe's verification of this run**, when it lands. Everything re-runs from
`/root/crucible/q55/`: `make_fixtures_q55.py`, `patch_gate_q55.py`, `run_matrix_q55.py`,
`run_matrix2_q55.py`, `q55_guard.py`, `census_q55.py` and `cleanup_sandboxes.py` are
self-contained; `out/` holds every cell's stdout and stderr plus `Q55-MATRIX.json`,
`Q55-MATRIX2.json`, `Q55-CENSUS.json` and `Q55-CLEANUP.json` (host-local — the repo carries 0 paths
under `out/`, E13's rule).
2. **No new item opened.** The Helm lane's executable set is empty and a task invented to fill it would
be invented work; the next Helm unit is the `cp` decision, not a task.
### Ask
Alexander's, unchanged: **(a)** the §4 adoption `cp` — collector `4e45021d…` + gate
`cd43284ff009…` — the only thing between Q31–Q45 §9 and production protection in `/root/.helm`;
**(b)** the `manifest_match` pin, stale since 2026-10-08; **(c)** the Q13 publication call. No ask of
the pipe: this run returned nothing to the pipe's own queue (the hygiene ledger's Q52 is Mercury's),
and the lane's own limits are discharged by measurement above.

## Run 23 — record correction: the four numbers, and a readback that survives its own overwrite
### Did
No unclaimed queue item was executable this run, and I did not invent one: **Q42 is zephyrus-sparkborn's,
Q52 is Mercury's, Q53 is the career lane held for Alexander**, and both this lane (Run 22) and the pipe
(`1ccf944`, reply 45 §6) have independently measured the Helm executable set empty — the next Helm unit is
a decision, not a task. So the unit is the one reply 44 (`0f9ac82`) and reply 45 (`1ccf944`) handed back:
**four byte figures and one identifier in my own Run 22 record are wrong**, and the wrong pairing sits
behind the §4 adoption `cp` cite, which is the one thing standing between Q31–Q45 §9 and production.
**Deliverable:** `recoveries/helm-pwdir-channel-refusal.md` **14,808 B → 20,820 B / sha256
`8d67248fd9acb73cb5cb0c39a5fb774232c02730f97e998a5f3292d54efbbcc1`** (+6,012 B, **append-only** — nothing
above the anchor edited, anchor count asserted `== 1` before the write, trailing newline asserted before
and after **on the written file**).
**Cause, and it is mine.** `rename_q55.py` renames `Q55` → `Q45S9` (+2 chars per occurrence) and changed the
gate's bytes **after** the byte figures were taken and **before** the digests were computed, so the record
published a **post-rename digest beside pre-rename bytes**. Measured this run from disk and the interpreter,
not from either reply: instrument `/root/crucible/q55/run23_verify.py`, artifact `out/R23-VERIFY.json`
(**2,685 B / sha256 `1bb9cd78e394d25ccea46a5d38c67b598d694c49462269911f357c3e858fc0c5`**,

Both gates: **2,735 lines / 126 `check("` registrations / trailing newline true**; `Q55` (upper) occurs **0**
times in both and `Q45S9` **2** (armed) / **3** (twin — the third is the twin's own cut comment), so the
rename is total. `_q45S9_pwd_sites` **0** in both; `_q55_pwd_sites` at **:435, :442, :451** armed and
**:435, :451** twin — 3 vs 2 sites, which *is* the single cut line and nothing else. The reply's
*"3,043 minus 23"* derivation is **wrong in kind**, not wrong by arithmetic: the anchor is the insertion
point, so the block is 3,024 B post-rename and 3,020 B pre-rename, and the subtraction only appears to
explain it.

22's witness-restore trace, disclosed there and not re-created here).
**The readback now survives its own overwrite — reply 45 §5.1's finding, closed.** `out/Q55-READBACK.txt`
on disk is the `8d105e9` read, so the `c4addca` read it was written to hold could not be re-derived from its
own artifact. New instrument `/root/crucible/q55/readback_r23.py`, artifact `out/R23-READBACK.json`, reading
**`/raw/commit/<rev>/<path>`** so the served body is the body *at that revision*, permanently:

**6 rows, 6 × served = git.** The two `served = disk false` rows at `c4addca` are the pipe's own three
appends since that revision (queue 951,756 → 957,453 B / `d8f54086…` → `d60d6dee…`; check-in 9,279 →
10,499 B / `2d815c65…` → `eae1c6b2…`) — named and dated, not a serve failure. The record is
**byte-identical at both revisions** (`d4c381f7…`), which is what makes today's corrected figures the first
change to this file since Run 22 landed.
**A defect of mine, hit inside this run and logged here rather than in a reply:** the first version of
`run23_verify.py` extracted the Q52 line with `startswith("PASS Q52")`, which never matches the two-space
rendering — the lane's own logged defect, reproduced by its author on a fresh artifact, corrected to a regex
before the run was recorded. The measured line is quoted above.
### Blocked
Nothing blocks the lane. The standing human gates are unchanged and none is new: the **§4 adoption `cp` —
now collector `4e45021d…` + gate `cd43284ff009…`, whose digests this run re-verified against the files on
disk**, the **`manifest_match` pin** (stale since 2026-10-08), **Q13's publication call** (item 13's decided
note controls over its `proposed_action`), **Q9's checksum handover**, **Q19's onboarding**. Q42 is
zephyrus-sparkborn's, Q52 is Mercury's, Q53 is the career lane's. Nothing deployed this run: `grep -c
HELM_COLLECTOR /root/.helm/bin/helm-selftest.py` = **0**, so Q40 stands and none of Q31–Q45 §9 is in
production.
### Next
1. Nothing is owed to the pipe from this run: reply 45 asks nothing of me, and both replies' corrections are
now applied to the artifact they correct.
2. **No new item opened.** The Helm executable set is empty and the queue's genuinely open items belong to
other lanes or to Alexander; the next Helm unit is the `cp` decision.
### Ask
Alexander's, unchanged: **(a)** the §4 adoption `cp` — collector `4e45021d…` + gate
`cd43284ff009d1cceb3aaa6a65b701d1076eaf801e32b705672601b4122b746a` (143,389 B / 2,735 lines / 126
registrations), re-verified on disk this run; **(b)** the `manifest_match` pin, stale since 2026-10-08;
**(c)** the Q13 publication call. No ask of the pipe.

(`https://forge.alexanderwhitestone.com/git/stackchain/troupe-standup/raw/commit/<rev>/<path>`, no
credential) by `python3 /root/crucible/q55/readback_r23.py eec3ff3`; artifact `out/R23-READBACK.json`
(**1,229 B / sha256 `9846ea9050802ca24d67a869e4facae7c750ee6a0bdbe3c8a9b07bd808372c18`**, host-local — the

**This file's own row defers to the artifact above** — appending this block changes this file's digest, so
the row for *this* commit is the next revision's readback and the chain stops here by design (Run 22's
landing-fill shape, with the regress named instead of chased). The artifact's `revision` field names which
revision each of its rows is dated at, which is the property reply 45 §5.1 asked for.
Live state at readback, unchanged: snapshot 14,039 B / `aa842b0fd88037f8…` / mtime_ns
`1791479579475780303`; held pin 120 B / `5b6d7071…` / mtime_ns `1791478687099553071`; ctime unmoved on both
this run. Deployed `/root/.helm/bin/` untouched, `grep -c HELM_COLLECTOR` = **0** (Q40 stands). Sandbox census
in `/root/crucible/q55/`: **0** (`ls | grep -c helm-legs` → 0). Nothing deployed, no another-party file
edited, `decisions/` and `inbox/` untouched, no secret printed.

## Run 24 — Q45S10: the discovery channel
### Did
Claimed and finished **the lane's named residual — the filesystem-discovery channel** (Helm lane; the limit
every record since Q45 has carried: *resolve every path the subject declares at runtime*. Q48 closed env
and argv, Q52 closed `Path.home()`/`expanduser`, Q45S9 closed `pwd.getpwuid`; **the search was the
remainder and the one channel no redirect can reach**). Deliverable:
`recoveries/helm-discovery-channel-seed.md` (this host). Queue block appended at the foot of
`WORK-QUEUE.md`. Scratch tree `/root/crucible/q56/`; nothing deployed, no `cp` into `/root/.helm/bin/`,
`decisions/` and `inbox/` untouched, no another-party file edited, no secret printed. Internal label
`Q45S10` follows `Q45S9`; the queue's Q52 is Mercury's and Q53 the career lane's.
**The class, measured on the shipped gate before the change.** `collector-discover.py` (31,076 B /
`1f3dae9e7018a656…`, the real collector `4e45021d…` with the held directory resolved at call time: walk up
from the module's own location, then scan the candidate roots, for the held pin) is **admitted on the same
terms as every other collector** — `Q39 OK: the subject refused its sentinel destination (probe rc=2,
sentinel written=False, other probe files=0, no traceback, live delta 0)` — and the suite is **green**:
**176 passed / 0 failed, ALL GATES PASS, live delta `{}`**, 13,918 B stdout, 11.9 s. The Q45
resolved-destination probe prints `HELD_DIR=None` — the module-level constant the copy declares — so check 2
passes **vacuously**: the gate is green on a subject whose held directory is the live one. The interpreter's
own verdict: run bare, both fixtures read the LIVE held pin (`held_body_sha256` =
`f27326e8b13d1dec9eb158fe40e5091f79dcaf73b47312c4e7d3958ba1d95d18`, the live pin's digest), and a scratch
HOME changes nothing (`probe-scratch-home.json`) — the subject never reads HOME, so Q52's redirect is
satisfied by a mechanism the subject does not use. The control shows the probe is not broken: the **eager**
form is **reported** (`FAIL Q45 … values={"HELM_HOME": "/root/.helm", "HELD_DIR":
"/root/.helm/data/held", …}`, 175/1). The call-time form is the blind one.
**The escape's write path, measured:** `shipped × discover --q52-witness` → rc 0 and **the live held pin
moves** (`5b6d70716153c3f4…` → `4e98bb00650e…`), restored byte-exact by the guard, with
`copy_pin_files_anywhere_in_sandbox` `[]`. Nothing inside the gate sees it.
**The fix, two inserts** (`patch_gate_q56.py`, every anchor asserted `count == 1`, trailing newline asserted
on the written file). (1) **The seed — prevention:** at the sandbox-creation site the sandbox is given its
own `.helm/data/held/stackchain-home.html.sha256` carrying a **decoy** digest
(`sha256(b"Q45S10 sandbox decoy pin")` = `1e0c8aeefeadd3a1af732b94b2b2b342dfc0a38446714f812305416323ee1ce3`),
so the copy's walk-up finds the sandbox's own tree first. A decoy, never the live bytes. (2) **The artifact
check — detection:** one more subject leg writes a snapshot into the sandbox (through the same wrapper as
every other leg: argv rewrite, rebuilt environment, per-leg census, live watch) and the artifact must not
carry the live held pin's digest — the only instrument that can see a call-time resolution, because the
probe is vacuous on it by construction.
**The pair.** Gate **`c56230e5a075c5a12fd2f0d336dcac71c1078cb692a9e6c995780098a051f13e`** (147,151 B /
**2,798** lines / **127** `check("` registrations — 126 + 1) on the Q45S9 gate `cd43284ff009…` (143,389 /
2,735 / 126): `out/DIFF-vs-q55.txt` = **2 hunks, +63 −0 lines, +3,762 −0 B**, and 143,389 + 3,762 = 147,151
exactly. Disarmed twin **`820b7afdff6821a092a64d8a5c24d27f33baaa624534e9f1bfe351ef065a6e4a`** (147,074 /
2,796 / 127): the seed's `write_text` statement cut, 3 lines removed and 1 added, **77 B smaller**.
**The matrix, 8 cells under the digest-verified guard** (`out/Q56-MATRIX.json`, `out/Q56-MATRIX2.json`):
shipped × discover **176/0 silent**; shipped × witness **the live pin moves** (restored); armed × discover
**177/0** with the artifact carrying the **decoy** and not the live digest (*"the live held pin's digest is
NOT in the sandbox artifact, and the sandbox decoy's digest IS"*); armed × witness `live delta {}` with the
pin **inside the sandbox**; **disarmed × discover 176/1** — `FAIL Q45S10 … artifact=… exists=True leg_rc=0
live_pin_digest=f27326e8b13d1dec… live_digest_in_artifact=True`; **disarmed × witness the live pin moves
again** — the seed is load-bearing; shipped × eager 175/1 (reported); armed × eager **177/0** — the seeded
sandbox resolves even the eager form inside. **Green pair ×5: rc 0, 177/0, 14,254 B each** (byte-stable),
live delta `{}` each; the shipped gate's own control on the real collector reproduces its historical
baseline to the byte (**176/0 at 14,044 B**). The +210 B on the armed runs is the seed's paths in the Q43
sandbox-census print plus the artifact leg and the new check's name; **no pre-existing check moved**.
**Regressions 11/11:** n1–n4 and dep-unparseable → Q39 rc 2; noparse → Q46 rc 2; undecodable → Q47 rc 2;
broken_dep → Q35 rc 2; n5 → rc 2 (its own destination rule, on the redirected sandbox dest); latin1 and bom
→ green 177/0 at 14,254 B, live delta `{}` on all eleven.
**Live, deployed, sandboxes, disk** (`out/Q56-CENSUS.json`, re-measured): delta 0 on bytes/sha256/mtime
across all 25 invocations — snapshot **14,039 B / `aa842b0fd88037f83115b4a54d617f27666f4de06ef84f9a64c8fd0a5f04656d` /
mtime_ns `1791479579475780303`**; held pin **120 B / `5b6d70716153c3f4bd82045d5d71edf88f793a240ce1275c3dfca5759d0ee297` /
mtime_ns `1791478687099553071`**; **ctime moved on both** (`1791957230760646867` /
`1791957230761646950`) — the guard restores of the four deliberately-live cells, disclosed. Deployed
`/root/.helm/bin/` untouched (five digests re-read: `ee0b36a82f23…` / `5c67473d8928…` / `7ed1bca8f9da…` /
`12570786ba70…` / `738699986778…`) and `grep -c HELM_COLLECTOR` = **0** — **Q40 stands, so none of
Q31–Q45S10 is in production.** Sandboxes **0 in the q56 tree and 0 across `/root/crucible`**; 406,212 B
reclaimed. Disk **45 G free of 154 (72 %)**.
**Six defects of mine, logged first in the record**, the first being that the initial PEP 562 `__getattr__`
design was wrong twice over — a global name lookup inside a function never consults module `__getattr__`, and
the gate *refuses* a subject carrying no `SNAPSHOT_PATH =` assignment (Q39's failed-conditions list) — so the
fixture was rebuilt to move only the held channel to call time, and the class statement moved with it. The
others: the patch script read and wrote one path (double-insert, caught by the byte identity); the first twin
cut one line of a three-line statement (`IndentationError`); the first diff-vs-shipped compared the file with
itself; the first byte assertion added line counts where bytes were needed; and the green byte count moved
14,044 → 14,254 on the real collector — recorded, not smoothed over.
### Blocked
Nothing blocks the lane. The standing human gates are unchanged and none is new: the **§4 adoption `cp` —
now collector `4e45021d…` + gate `c56230e5a075…`** (superseding `cd43284ff009…` / `78b290ecf2d9…` /
`e4967da9…` / `a951dbe8…`), the **`manifest_match` pin** (stale since 2026-10-08), **Q13's publication
call** (item 13's decided note controls over its `proposed_action`), **Q9's checksum handover**, **Q19's
onboarding**. Q42 is zephyrus-sparkborn's, Q52 is Mercury's, Q53 is the career lane held for Alexander. No
counterparty check-in or reply has landed since the 2026-10-14 03:50Z hygiene ledger
(`git log --oneline --since=2026-10-14T00:00`: nothing after `8ba7c8e`).
### Next
1. **The pipe's verification of this run**, when it lands. Everything re-runs from `/root/crucible/q56/`:
`setup_q56.py`, `patch_gate_q56.py`, `run_matrix_q56.py`, `run_matrix2_q56.py`, `census_q56.py` and
`q56_guard.py` are self-contained; `out/` holds every cell's stdout and stderr plus `Q56-MATRIX.json`,
`Q56-MATRIX2.json`, `Q56-CENSUS.json` and `DIFF-vs-q55.txt` (host-local — the repo carries 0 paths under
`out/`, E13's rule).
2. **No new item opened.** The Helm lane's executable set is empty again — the adoption, Q9, Q13/Q19 and Q42
are human- or counterparty-gated — so the next Helm unit is a decision, not a task.
### Ask
Alexander's, unchanged: **(a)** the §4 adoption `cp` — collector `4e45021d…` + gate
`c56230e5a075c5a12fd2f0d336dcac71c1078cb692a9e6c995780098a051f13e` (147,151 B / 2,798 lines / 127
registrations) — the only thing between Q31–Q45S10 and production protection in `/root/.helm`; **(b)** the
`manifest_match` pin, stale since 2026-10-08; **(c)** the Q13 publication call. No ask of the pipe: this run
returned nothing to the pipe's own queue (Q52 is Mercury's, Q53 Alexander's), and the lane's named residual
is discharged by measurement above.

insertions and 0 deletions in total** — the authoritative figures. The append script's own printed byte
deltas (+7,769 / +8,936) are superseded by them and are recorded as a defect of mine: the working tree
moved under the append (the script read the queue at 959,834 B where `HEAD` carries 970,138 B), so its
`before` figures were read from a state that no longer held when it wrote. The final content is verified
against the revision rather than against the script's own arithmetic: each block appears exactly once, the
03:50Z pipe block precedes the Run 24 block, and `git diff` is insertions-only. `head_at_read` =
`32ad55b3ed5b715a6a15fa79841ebae41655e60a`.

`1791478687099553071`; ctime_ns on both as the census carries (the guard restores' trace). Deployed
`/root/.helm/bin/` untouched, `grep -c HELM_COLLECTOR` = **0** — Q40 stands, so none of Q31–Q45S10 is in
production. Nothing deployed, no another-party file edited, `decisions/` and `inbox/` untouched, no secret

### Run 24 landing correction (mine, logged not deleted)
The Run 24 landing block above claims *"the working tree moved under the
append (the script read the queue at 959,834 B where `HEAD` carries 970,138
B)"*. **That claim is false, and the cause is my own instrument's unit, not a
concurrent writer.** `append_r24.py` and `append_landing_r24.py` printed
`len(before)` and `len(now)` from `Path.read_text()`, which decodes UTF-8 —
so every one of those figures is a **character** count printed beside a byte
count. Measured now, both ways, from disk and the committed blob
(`verify_tree_r24.py`): the queue is 978,022 **bytes** = 959,834 **characters**
(the 10,304 difference is multi-byte sequences: em-dashes, ellipses, `§`), and
this file is 29,217 **bytes** = 28,840 **characters** at `32ad55b`. There was no
concurrent writer; the tree never moved; and the writes were never at risk,
because every assertion that mattered was on bytes — the sha256s, the trailing
newline and the anchor counts (`read_text()` for anchors, `read_bytes()` for
digests, in the same scripts, side by side).
**The content is verified against the revision, not against the scripts'
arithmetic:** `verify_tree_r24.py` reads `git cat-file -p 32ad55b:<path>` and
the disk copy for all three files — `WORK-QUEUE.md` disk == committed
(978,022 B / `1ea689a790267b4c…`, suffix 0 B), the record disk == committed
(13,218 B / `83acffe0222d46e7…`), and this file disk == committed + **2,518 B**
of landing block, `startswith` true. `git diff --numstat 8ba7c8e 32ad55b` =
**84/0 and 116/0, 200 insertions and 0 deletions** — the authoritative landing
figures, and the only ones this correction stands behind. The lane's own
logged defect class (Run 22's prefix-vs-full comparison, Run 23's
post-rename bytes) in a new place: a unit printed as its neighbour's unit. The
fix for the next run is one line — `len(p.read_bytes())` — and it is written
down here so the next run does not rediscover it.

## Run 25 — reply 47 discharged: the mispaired counts, the tree-scoped bytes, the reclaim figure, and the provenance defect
### Did
The pipe verified Run 24 (reply 47, queue block `a87745a`) and returned three corrections plus a
provenance defect against `recoveries/helm-discovery-channel-seed.md`. Each was **re-measured from the
git blobs and the scratch tree, not accepted from the reply**; all four confirmed. Deliverable: the
record's §8, appended append-only (record pre-append **13,218 B / sha256
`83acffe0222d46e7435aed2e79dffca39e503554b2110e393fbd0cc12ad30265`** at `32ad55b`; the post-append
digest is this run's landing block, not this paragraph — a file cannot cite its own final digest).
Anchor count asserted `== 1` before the write, trailing newline asserted on the written file. Scratch tree
`/root/crucible/q57/`; nothing deployed, no `cp` into `/root/.helm/bin/`, `decisions/` and `inbox/`
untouched, no another-party file edited, no secret printed. Clock: 2026-10-14T08:1x–08:3xZ (read
immediately before the edits).
**C1 — the landing correction's character/byte pair is mispaired. Confirmed with the correct pairs**
(`/root/crucible/q57/measure_r25.py`, artifact `out/R25-MEASUREMENTS.json`):
$ cd /root/crucible/q57 && python3 measure_r25.py
8ba7c8e WORK-QUEUE.md bytes= 970138 chars= 959834 delta= 10304 sha=0c754e51b37d
32ad55b WORK-QUEUE.md bytes= 978022 chars= 967603 delta= 10419 sha=1ea689a79026
32ad55b checkins/2026-10-14-merlin.md bytes= 29217 chars= 28840 delta= 377 sha=a2b4fd39740b
50bf350 checkins/2026-10-14-merlin.md bytes= 33771 chars= 33364 delta= 407 sha=33e452cd5b9d
a87745a WORK-QUEUE.md bytes= 983165 chars= 972681 delta= 10484 sha=aaab66ab9d1e
The correction's *"978,022 bytes = 959,834 characters"* pairs `32ad55b`'s bytes with `8ba7c8e`'s
characters; the 10,304 it prints is the `8ba7c8e` pair's own difference (`32ad55b`'s is 10,419); the
printed +7,769 is the character delta, the byte delta is +7,884; the named cause (`len()` of a decoded
string) is right; the second pair (29,217 B = 28,840 chars) is correct as written.
**C2 — stdout byte figures are a function of the gate's own directory length. Confirmed, coefficient
measured.** The sandbox is created with `dir = Path(__file__).resolve().parent`, so sandbox paths in
stdout grow with the tree name. Both gates copied byte-identically into
`/root/crucible/q57/q56-plus-twelve` (tree name +12, full path +16 per occurrence) and the two green cells
re-run (`measure_c2_r25.py`, `diff_c2_bytes_r25.py`, artifacts `out/R25-C2.json` /
`out/R25-C2-BYTES.json`):
g1-shipped-real rc=0 suite=176/0 stdout=14140 B stderr=1264 B 12.6s moved={} occurrences: 6
g2-armed-real rc=0 suite=177/0 stdout=14350 B stderr=1726 B 15.0s moved={} occurrences: 6
growth per cell: 96 B (predicted 12 x 6 = 72 was MY error - the tree was nested under q57/, so the
full path is +16 per occurrence, and 6 x 16 = 96); len(replaced) - len(orig) = 0 after replacing
every occurrence of the long path with the short one -> the tree path fully explains the growth
the +210 B armed-vs-shipped delta in the +16 tree: 210 (PORTABLE - both gates print the path 6 times)
Portable citations: the verdict, rc, suite counts, digest pair, +210 B delta. Tree-scoped: 14,044 /
14,254. §4's "byte-stable across all five" stands as written (five runs, one tree, measured 5 × 14,254 B).
**C3 — the 406,212 B reclaimed figure has no derivation. Confirmed.** `out/Q56-CENSUS.json` records
`"cleanup": {"removed": [{"path": "/root/crucible/q56/__pycache__", "note": "the C32 class"}],
"reclaimed_bytes": 406212, "after_count": 0}` — one removed path, no byte count; the sum of recorded
per-path bytes is 0. Restated in §5: the removal is recorded, the figure is **Testimony only**.
**P — provenance. Confirmed and fixed prospectively.** `32ad55b` and `50bf350` are authored
`Timmy <timmy@stackchain.ai>` (the clone's configured identity); `git log --author=merlin` = **82**, the
lane's earlier commits. Cause: Run 24's append scripts carry no commit step, so the shell commit ran
without the lane's `-c user.name=Merlin -c user.email=merlin@agents.invalid` overrides. Published history
is not rewritten (both revisions are cited by the queue's Run-24 block and reply 47); the fix is
prospective and asserted — this run's commits carry the Merlin identity, re-counted before the push.
**Live state, unchanged and re-measured:** snapshot 14,039 B / `aa842b0fd88037f83115b4a54d617f27666f4de06ef84f9a64c8fd0a5f04656d`

delta `{}` across every invocation this run (bytes/sha256/mtime_ns/ctime_ns on both). Deployed
`/root/.helm/bin/` untouched, `grep -c HELM_COLLECTOR` = **0** — Q40 stands, so none of Q31–Q45S10 is in
production. Sandboxes 0 in the q57 tree; the lengthened test tree holds the two gate copies and nothing
else. Disk 45 G avail of 154.
**Two defects of mine, logged first:** the C2 coefficient (12 assumed, 16 measured — the test tree was
nested under `q57/`), and nothing else. None of the four corrections changes any mechanism, digest, line
count or verdict in §1–§7; §6's adoption pair (`4e45021d…` + `c56230e5a075…`) is untouched.
### Blocked
Nothing blocks the lane. The standing human gates are unchanged and none is new: the **§4 adoption `cp` —
collector `4e45021d…` + gate `c56230e5a075c5a12fd2f0d336dcac71c1078cb692a9e6c995780098a051f13e`**
(superseding `cd43284ff009…` / `78b290ec…` / `e4967da9…` / `a951dbe8…`), the **`manifest_match` pin**
(stale since 2026-10-08), **Q13's publication call** (item 13's decided note controls over its
`proposed_action`), **Q9's checksum handover**, **Q19's onboarding**. Q42 is zephyrus-sparkborn's, Q52 is
Mercury's, Q53 is the career lane held for Alexander. No counterparty check-in or reply has landed since
the 2026-10-14 06:17Z Run-24 verification (`git log --oneline --since=2026-10-14T06:00`: nothing after
`a87745a`).
### Next
1. **The pipe's verification of this run**, when it lands. Everything re-runs from `/root/crucible/q57/`:
`measure_r25.py`, `measure_c2_r25.py`, `diff_c2_r25.py` and `diff_c2_bytes_r25.py` are
self-contained; `out/` holds `R25-MEASUREMENTS.json`, `R25-C2.json`, `R25-C2-BYTES.json` and the two
lengthened-tree stdout captures (host-local — the repo carries 0 paths under `out/`, E13's rule).
2. **No new item opened.** The Helm lane's executable set is empty (Run 24's residual — a destination
handed over by a third party at runtime — was ruled a hypothesis with no fixture); the next Helm unit
is the `cp` decision, not a task.
### Ask
Alexander's, unchanged: **(a)** the §4 adoption `cp` — collector `4e45021d…` + gate
`c56230e5a075c5a12fd2f0d336dcac71c1078cb692a9e6c995780098a051f13e` (147,151 B / 2,798 lines / 127
registrations) — the only thing between Q31–Q45S10 and production protection in `/root/.helm`; **(b)**
the `manifest_match` pin, stale since 2026-10-08; **(c)** the Q13 publication call. No ask of the pipe:
reply 47 asked nothing new of this lane, and its four corrections are discharged above by measurement.

The check-in's own row is the file at `2b834d4` **before this append** — appending this block changes
this file's digest, so the row for the commit that carries this block is the next revision's read, and
the chain stops here by design (Run 22's landing-fill shape). The landing deltas are
`git diff --numstat a87745a 2b834d4`: **11/0 on the queue, 105/0 on this file, 71/0 on the record —

**Provenance, the defect fixed prospectively:** `2b834d4` is authored `Merlin
<merlin@agents.invalid>`; `git log --author=merlin` = **83** before the push (was 82), asserted by
`finish_r25.py` in the same run. `32ad55b` and `50bf350` remain Timmy-authored by the clone's

cannot be edited, so the correction lives here. The one-byte figure is the only wrong number in this
run's artifacts: every in-file figure — the three landing digests (`decd3350585dd169…` /
`27cddb8dada786a3…` / `f1ceb4194839a90f…`), the byte sizes (18,527 / 986,844 / 41,168), the

## Run 26 — reply 48's four citation corrections discharged: the Q34 writer, the `out/` paths, the clock, the byte
### Did
Reply 48 verified Run 25 on the pipe's own instrument (all four discharges confirmed, the C2 coefficient
confirmed) and returned four citation corrections against `recoveries/helm-discovery-channel-seed.md`
and this file. Each verified and fixed by measurement; none is a figure and none moves a conclusion.
Deliverable: the record's §9, appended append-only (record 18,527 B / `decd3350585dd169…` → measured at
landing — this file does not cite its own post-append digest; anchor count and trailing newline asserted
on the written file). Scratch tree `/root/crucible/q57/`; nothing deployed, `decisions/` and `inbox/`
untouched, no another-party file edited, no secret printed. Clock: 2026-10-14T08:3x–08:4xZ.
**(C1) The lengthened tree holds three files, and the third is the gate's own output — measured.**
`/root/crucible/q57/q56-plus-twelve/` holds `helm-selftest-q55.py` (143,389 B / `cd43284ff009…`),
`helm-selftest-q56.py` (147,151 B / `c56230e5a075…`) and `Q34-NULL-EVIDENCE.txt` (**694 B / sha256
`f46b2f3b677552d5f1417b9e3d848bba235cda4711cb1f0447efcde160fb788f`**, mtime 08:13:32Z, between the two
re-run cells). The writer is the gate itself — `helm-selftest-q56.py:2551`:
`_q34_dump = Path(__file__).resolve().parent / "Q34-NULL-EVIDENCE.txt"` — so **the artifact the pipe
observed "following the lane" across q49/q55/q56 is the Q34 null-pointer check's own output, written
beside whichever gate ran**; its `collector` line names the subject that run was given
(`/root/crucible/q48/helm-collect.py`). The 0-sandbox census is unaffected; the "nothing else" sentence
is corrected in §9.
**(C2) Every `out/…` citation was one level off — fixed by moving the artifacts, digests asserted
unchanged.** `run26.py` created `out/` and moved all eleven files; every digest before == after
(`out/R26-MANIFEST.json`); every citation now resolves: `out/R25-MEASUREMENTS.json` 2,405 B /
`111b949ffb8c…`, `out/R25-C2.json` 1,274 B / `366593fd8149…`, `out/R25-C2-BYTES.json` 1,735 B /
`887578d0a2bf…`, `out/R25-READBACK.json` 1,126 B / `39803e50e668…`, `out/R25-READBACK-FINAL.json` 869
B. The cause is mine: Run 25's scripts wrote to the tree root while the prose kept Run 24's `out/` form.
No Run-25 figure was wrong — only the paths.
**(C3) The landing block's read clock is the artifact's field, not an approximation:** `read_at`
**2026-10-14T08:23:20Z** (`out/R25-READBACK.json`, revision `2b834d4`) and **2026-10-14T08:31:19Z**
(`out/R25-READBACK-FINAL.json`, revision `0c8aef5`). No figure depends on either clock.
**(C4) The landing commit's one-byte figure** — the `bc95796` erratum, independently confirmed by reply
48's addendum (concurrent, correctly attributed). Nothing further owed.
**Live state, unchanged and re-measured:** snapshot 14,039 B / `aa842b0fd88037f83115b4a54d617f27666f4de06ef84f9a64c8fd0a5f04656d`
/ mtime_ns `1791479579475780303` / ctime_ns `1791957230760646867`; held pin 120 B /
`5b6d70716153c3f4bd82045d5d71edf88f793a240ce1275c3dfca5759d0ee297` / mtime_ns `1791478687099553071` /
ctime_ns `1791957230761646950` — **both ctime_ns values are the pair Run 24's guard restores left, so
nothing has written either object since**. Deployed `/root/.helm/bin/` untouched, `grep -c
HELM_COLLECTOR` = **0** — Q40 stands, so none of Q31–Q45S10 is in production. Sandboxes 0; the q57 tree
now holds its artifacts under `out/` (E13's rule: 0 paths under `out/` in the repo tree). Disk 45 G avail
of 154.
**Defects of mine, logged first:** the `out/` citation regression (the citation form survived the tree
move; the write path did not), the unlisted "nothing else" sentence, and the clock approximation — none
of the four corrections touches a figure, digest, mechanism or verdict, and the adoption pair
(`4e45021d…` + `c56230e5a075…`) is untouched.
### Blocked
Nothing blocks the lane. The standing human gates are unchanged and none is new: the **§4 adoption `cp` —
collector `4e45021d…` + gate `c56230e5a075c5a12fd2f0d336dcac71c1078cb692a9e6c995780098a051f13e`**, the
**`manifest_match` pin** (stale since 2026-10-08), **Q13's publication call** (item 13's decided note
controls over its `proposed_action`), **Q9's checksum handover**, **Q19's onboarding**. Q42 is
zephyrus-sparkborn's, Q52 is Mercury's, Q53 is the career lane held for Alexander. Reply 48 asks nothing
of this lane and owes nothing in either direction; its four corrections are discharged above.
### Next
1. Nothing is owed to the pipe from this run: reply 48's four citation corrections are discharged, its
own §0 mistakes are its own to keep, and its §5 queue block is its own commit.
2. **No new item opened**, restated rather than inherited: the Helm executable set is empty, and the one
channel §7(d) names (a destination handed over by a third party at runtime) is a hypothesis with no
fixture — the ruling this pipe already filed for the equivalent case. The next Helm unit is the `cp`
decision, not a task.
### Ask
Alexander's, unchanged: **(a)** the §4 adoption `cp` — collector `4e45021d…` + gate
`c56230e5a075c5a12fd2f0d336dcac71c1078cb692a9e6c995780098a051f13e` (147,151 B / 2,798 lines / 127

## Run 27 — 2026-10-14 (Merlin)
### Did
Reply 51's three open rows are closed, each by measurement on this host, and the lane's stale
coefficient is fixed.
1. **C2 coefficient 72 → 16 (the item both reply 49 and reply 51 named).** The tree path in the
rewritten copy, `/root/crucible/q57/q56-plus-twelve`, is **34** chars against the baselines'
`/root/crucible/q55` / `/root/crucible/q56` at **18**, so the per-occurrence delta is **16**, not 12.
Six occurrences per cell, so **16 × 6 = 96** — which is exactly what both cells grew
(`diag_c2_r27.py`, measured on bytes). Substituting the long path back for each cell's own root
gives `len(replaced) − len(orig) = 0` on both, so the tree path explains the growth completely.
Four fields, one value each, asserted before the write and re-hashed after (`fix_c2_r27.py`):
`out/R25-C2-BYTES.json` 1,735 B `887578d0a2bf…` → 1,735 B `9fd5f1d23016…`;
`out/R25-C2.json` 1,274 B `366593fd8149…` → 1,274 B `0c0b2cb65187…`. **Both files are 0 bytes long
across the edit — `72` and `16` are the same width — so the digests are the only evidence.**
Nothing else moved: growth 96/96, `delta_orig`/`delta_long_tree` 210/210, `delta_portable` true,
both gate digests (`cd43284ff009…`, `c56230e5a075…`), every byte count.
2. **The hyphenated-subject erratum, two loci.** `e388225` **and** `121da2f` both carry
`check-ins/2026-10-14-merlin.md` in their subjects; the real path is `checkins/…`. Commit messages
cannot be edited, so both are recorded here and in reply 52 §2.
3. **The `2b834d4` subject size — restated, since reply 50 dropped it.** Its subject cites the seed at
13,218 B, which is the parent's size: `git cat-file -s 2b834d4:recoveries/helm-discovery-channel-seed.md`
→ **18527** (blob `4e3cca9cffd2…`); `2b834d4^` → **13218** (blob `4f53c93a708d…`). Recorded here and
in reply 52 §3.
4. **`:688` scoped as an append** (the check-in is append-only): the corrected reading is **no Run-25
byte or digest was wrong — only the paths and one coefficient**. Reply 49's "the unnamed second
defect" framing was narrowed by reply 51 and accepted here; the record's `:293` parenthetical
survives as written.
5. **Live state re-measured, unchanged:** snapshot 14,039 B / `aa842b0fd880…` / mtime_ns
`1791479579475780303` / ctime_ns `1791957230760646867`; held pin 120 B / `5b6d70716153c3…` /
mtime_ns `1791478687099553071` / ctime_ns `1791957230761646950` — both ctimes still the Run-24
guard-restore pair, so nothing has written either object. Deployed bin 5 files, `HELM_COLLECTOR`
**0** → Q40 stands. Disk 45 G avail of 154 (72 % used, `df -h /`).
**Defects of mine, logged first.** The coefficient itself was wrong in Run 25's artifacts and sat
there through two replies that quoted it as a figure while grading it as harmless — it is fixed, and
the fix is that a *prediction* was wrong, which neither the byte nor the digest vocabulary covers. My
first diagnostic this run also miscounted the shipped cell's baseline as 0 occurrences, because it
grepped for `/root/crucible/q56` where the shipped cell's root is `/root/crucible/q55`; the
`diff_c2_bytes_r25.py` count of 6 was right all along. Both are logged, not smoothed.
**Attribution.** Reply 47 §4's provenance fault: the clone's configured identity is
`Timmy <timmy@stackchain.ai>`, so Run 24–26's commits landed under that author. This run's commits
carry `-c user.name=Merlin -c user.email=merlin@agents.invalid`. Merlin-authored commits at HEAD: 87
before this run.
### Blocked
Nothing on the lane. The Helm executable set is empty; the §4 `cp` is a decision, not a task, and it
is Alexander's — collector `4e45021d…` (29,954 B / 720 lines) + gate `c56230e5a075…` (147,151 B /
2,798 lines / 127 registrations) is the only thing that puts Q31–Q45S10's protection into production.
### Next
- No new item opened — the next Helm unit is the §4 adoption decision, not a task. The lane stays
closed to new work until that lands.
- Open asks, all Alexander's and not re-raised to the pipe: the `manifest_match` pin stale since
2026-10-08, the Q13 wording call (the `magazine-040` replacement sentence, drafted and waiting),
and log rotation / `docker system prune`.
- If a reply asks for a §"Readback" append (the lane's standing convention), it lands as one.
### Ask
One line from Alexander, and it is the same one the last three ticks have asked for: **do the §4
`cp` of collector `4e45021d…` + gate `c56230e5a075…` into `/root/.helm/bin/` — adopt or hold?** Every
gate from Q31 to Q45S10 is verified and unmoved in production because `HELM_COLLECTOR` reads 0 in
the deployed bin. This is the single line that turns the lane's work into production protection, and
the lane cannot take it without approval.
### Readback — landing verified over the anonymous raw path
Both files re-fetched from the forge with no credential and compared byte-for-byte against disk
(`q57/readback_r27.py`, artifact `out/R27-READBACK.json`):

## Run 28 — G10: the deployed page is a stale generation, and the self-test cannot see it
### Did
No unclaimed queue item was executable and I did not invent one: **Q42 is
zephyrus-sparkborn's, Q52 is Mercury's, Q53 is the career lane's, Q9/Q13/Q19 are
gated on Alexander**, and Q49's `Status: open and unclaimed` at
`WORK-QUEUE.md:6847` is stale — the queue's own hygiene ledger at `:8026` records
it CLOSED. So the unit is the one Helm defect the lane had **measured and labelled
but never fixed**: the public Helm page publishes a green "match" that is false,
and the self-test cannot see it.
**Deliverable:** `recoveries/helm-deployed-page-generation.md` (**9,953 B** at the
write; the post-append digest is this run's landing block). Queue block appended
at the foot of `WORK-QUEUE.md`. Scratch tree `/root/crucible/q58/`; nothing
deployed, no `cp` into `/root/.helm/bin/`, no write to the live document root, no
`--deploy` anywhere in the G10 block, `decisions/` and `inbox/` untouched, no
another-party file edited, no secret printed. Clock 2026-10-14T13:0x–13:2xZ.
**The finding, measured.** The Helm's pinned site `https://www.stackchainmagazine.net/`
is now **HTTP 200 / 217,163 B / sha256 `c34ae2c245117ca7…`**; the held pin is
`f27326e8b13d1dec…`, **pinned 2026-10-08T16:58:07.100Z**, so
**`pin_matches_live_now: false`**. The **deployed** page
`/var/www/alexander-whitestone/helm/index.html` is **9,865 B / sha256
`427b7b54c69b18d270288910fc810732463129f48ec4bdd7dbc75cdb22997ce4`** / mtime
**2026-10-11T08:57:14.017Z** and renders `<span style="color:#22c55e">match</span>`
with **`as_of=False`, `not_rechecked=False`**. The renderer carrying the fix is
`helm-render.py` 21,766 B / `5c67473d89283c3d…` / mtime
**2026-10-11T11:12:43.756Z** — **8,129.7 s later**. Rendering the real snapshot
through the real renderer, `--out <scratch> --as-of 2026-10-14T00:00:00.000Z`,
gives **rc 0, 11,798 B / sha256 `f32191223931e74b421c1412833d6f225385f01d6ab2ff6dd4a38b414f25bccc`**,
carrying *"as of 2026-10-08T17:12:59.458Z · 5d 6h 47m ago · not re-checked since"*.
**The fix exists, works, and was never deployed.**
**Why the self-test was green.** `helm-selftest.py:420-421` runs the qualifier
check on a **synthetic fixture** at a pinned clock (`hr.SNAPSHOT = fp`), and
`:422-425`'s *"build_page() writes nothing"* proves only that `build_page` did not
overwrite production. **Neither reads the deployed artifact.** That is the Q34/Q40
law in a new place: a gate that tests the producer cannot vouch for the artifact
in the document root.
**The fix — gate G10, four checks**, on Q45S10's `c56230e5a075…` (147,151 / 2,798 /
127): **`helm-selftest-q58.py` 153,469 B / sha256
`3b98b62fa5c7ea626091f6d0f63566de79818ae414bcffe323dd1ddd53956158` / 2,916 lines /
131 `check("` registrations**. (1) the contract on **real data** through the
renderer's own CLI — PASS; (2) **the deployed page carries the qualifier** —
**FAIL**; (3) the predicate discriminates — PASS; (4) read-only, bytes + sha256 +
mtime_ns identical around the gate — PASS.
**The discriminator, with the prediction stated before the run and met exactly.**
`run_twin_q58.py` twins the gate with `_g10_deployed` repointed at a **scratch**
current-generation render (`ast`-asserted, and no live-path token in any
non-comment line of the G10 block). **Shipped: rc 1, 180 passed / 1 failed**, stdout
15,055 B / `e8304379529c4c83…`, stderr 1,791 B. **Twin: rc 0, 181 passed / 0
failed, ALL GATES PASS**, stdout 14,824 B / `fe8c8c72825962d9…`. A red row that
cannot go green proves nothing; this one goes green on the artifact it exists to
check.
**Live state, delta 0 across all four gate invocations** (bytes + sha256 +
mtime_ns): page 9,865 B / `427b7b54c69b18d2…` / `1791709034017837233`; snapshot
14,039 B / `aa842b0fd880…` / `1791479579475780303`; held pin 120 B / `5b6d7071…` /
`1791478687099553071`. **Sandboxes 0/0 both ways** (shallow glob and recursive
`rglob`) before and after. Deployed bin unchanged, five digests re-read
(`ee0b36a82f23…` / `5c67473d8928…` / `7ed1bca8f9da…` / `12570786ba70…` /
`738699986778…`); **`grep -c HELM_COLLECTOR` = 0** on the deployed self-test, so
**Q40 stands and G10 is not in production**. Disk 45 G avail of 154 (72 %).
**Byte-stability measured, not asserted.** Two shipped runs are both 180/1 at
15,055 B and `byte_stable_stdout` reads **false** — the difference is `mkdtemp`
suffixes in the sandbox path the gate prints (`/tmp/tmp8wl8eb44` vs
`/tmp/tmpsp0jt2_3`; `helm-legs-gb5_6rox` vs `helm-legs-5rzmq0xa`). The four **G10
rows are byte-identical across both runs**, and normalising the four path patterns
gives stdout sha256 **`1958d8212fa60e4458ba85b86221e459dcd2f7eaffc0351668e6b74f31e77856`**
on both with **residual differing lines: 0**.
**Six defects of mine, logged first in the record:** two claims in one cell (the
first G10 check 3 asserted both the predicate's soundness and the finding, which
would have made the twin 180/1 and hidden the discriminator); a report filter
written from memory — `startswith("PASS")` never matches the two-space rendering,
the lane's own logged class reproduced on a fresh artifact; a live-path assertion
that fired on G5's read-only check and then on G10's own comment;
`byte_stable_stdout: false` reported as found with the cause measured;
`ast.unparse`'s single quotes; and `pathlib.Path` in a gate that imports
`from pathlib import Path`.
### Blocked
Nothing blocks the lane. The standing human gates are unchanged and none is new:
the **§4 adoption `cp` — now collector `4e45021d…` + gate
`3b98b62fa5c7ea626091f6d0f63566de79818ae414bcffe323dd1ddd53956158`** (superseding
`c56230e5a075…` / `cd43284ff009…` / `78b290ecf2d9…` / `e4967da9…`), the
**`manifest_match` pin** (now shown to be **false** — §1), the **Q13 publication
call** (item 13's decided note controls over its `proposed_action`), **Q9's
checksum handover**, **Q19's onboarding**. Q42 is zephyrus-sparkborn's, Q52 is
Mercury's, Q53 is the career lane's. Nothing deployed this run.
### Next
1. **The pipe's verification of this run**, when it lands. Everything re-runs from
`/root/crucible/q58/`: `measure_r28.py`, `render_r28.py`, `patch_gate_q58.py`,
`run_gate_q58.py`, `run_twin_q58.py`, `census_q58.py`, `summarise_r28.py` and
`compare_r28.py` are self-contained; `out/` holds `R28-MEASURE.json`,
`R28-RENDER.json`, `R28-GATE.json`, `R28-TWIN.json`, `R28-CENSUS.json`, both
repeat-run captures and the twin's gate (host-local — the repo carries 0 paths
under `out/`, E13's rule).
2. **No new item opened.** The Helm executable set is empty and the queue's
genuinely open items belong to other lanes or to Alexander; the next Helm unit
is the `cp` decision plus the re-render, both of which are Alexander's.
### Ask
Alexander's, unchanged and now two-part: **(a)** re-render and re-deploy the Helm
page — the command is in the record's §1 — because the public page currently
publishes a green "match" against a pin that measurably does not match, with no
clock and no disclaimer; **(b)** the §4 adoption `cp` — collector `4e45021d…` +
gate `3b98b62fa5c7ea62…` — the only thing between Q31–Q45S10 and production
protection in `/root/.helm`. No ask of the pipe: this run returned nothing to the
pipe's own queue, and G10's own discriminator is discharged by the twin above.

**This file's own row defers to the next revision's read** — appending this block
changes this file's digest, so the row for the commit that carries this block is
the next readback and the chain stops here by design (Run 22's landing-fill
shape).
**The landing delta, measured from git rather than from the append script.**
`git diff --numstat 7af50b5^ 7af50b5` = **72/0 on the queue, 124/0 on this file,
149/0 on the record = 345 insertions, 0 deletions.** The queue's byte delta is
**1,062,291 → 1,067,607 B = +5,316**, and my block is **5,322 B**; the 6-byte
difference is my block's leading `\n---\n\n` aligning with the separator the
parent already carried, which is also why git counts **72** added lines rather
than the 74 my block's own newline count would suggest. Reconstruction verified
byte-exact: `parent[:1,060,132] + block + parent[1,060,138:] == rev` is **True**,
so the pipe's `**Erratum, mine: the 13:09Z tick…**` block is intact and keeps its
own separator. **No another-party content was clobbered.**
**One defect of mine, logged here rather than smoothed:** the append script's own
printed `before` figure for the queue was **1,060,143 B** against a shared prefix
of **1,060,132 B** — 11 bytes stale, because `sha(QUEUE)` and the later
`QUEUE.read_bytes()` are two separate reads and the pipe was writing the file
between them (its erratum is stamped `2026-10-14T13:26:06Z`, after my 13:25:50Z
append and before my 13:27:05Z commit). The file content is correct and every
assertion that mattered was on bytes read once and written once; only the printed
diagnostic is stale. **The git figures above are the authoritative ones**, and the
check-in was unaffected — `parent is a prefix of rev: True`, residual **0 B**,
124 lines = numstat 124/0 — because the pipe does not write my check-in. This is
the *concurrent-writer* form of Run 24's logged defect, not its *unit* form: the
units were bytes throughout.
**Live state at the landing, re-read and unchanged:** deployed page 9,865 B /

## Run 29 — G11: the pin pill that outlived its reading
### Did
No unclaimed queue item was executable and none was invented: **Q42 is
zephyrus-sparkborn's (closed at `da28ef0`), Q52 is Mercury's (closed at `4010b96`), Q53
is Mercury's (open), Q9/Q13/Q19 are gated on Alexander**, and the queue's own hygiene
ledger records the Helm executable set empty. So the unit is the half of Run 28's own
finding the fix does not reach — named by the control plane's re-derivation of G10
(`WORK-QUEUE.md`, 2026-10-14, commit `7ec2172`: *"the match/drift pill still reads the
frozen `manifest_match` field (renderer :323/:326), so a re-rendered page would show a
green 'match' beside 'as of … not re-checked since' while the pin provably no longer
matches the live body — internally inconsistent, and the false claim survives"*),
re-measured here before any edit and confirmed.
**Deliverable:** `recoveries/helm-pin-pill-staleness.md` (**14,839 B** at the write; the
post-append digest is this run's landing block, not this paragraph). Queue block appended
at the foot of `WORK-QUEUE.md`. Scratch tree `/root/crucible/q59/`; nothing deployed, no
`cp` into `/root/.helm/bin/`, no write to the live document root, no `--deploy` anywhere,
`decisions/` and `inbox/` untouched, no another-party file edited, no secret printed.
Clock from the artifacts: `R29-MEASURE.json` `generated_at 2026-10-14T15:53:07+00:00`,
`R29-GATE.json` `generated_at 2026-10-14T15:59:55+00:00`.
**The finding, measured.** The held pin is
`f27326e8b13d1dec9eb158fe40e5091f79dcaf73b47312c4e7d3958ba1d95d18 stackchain-home.html
pinned 2026-10-08T16:58:07.100Z` (120 B / file sha256 `5b6d70716153c3f4…` / mtime_ns
`1791478687099553071`); the live body `https://www.stackchainmagazine.net/` fetched this
run reads **HTTP 200 / 217,163 B / sha256 `c34ae2c245117ca73ba5720b2c22b6fab689840070ff68cda7bffe3e723986d4`**,
so **`pin_matches_live_now` is false**. The snapshot's `stackchain_site` block still
carries `manifest_match: true` and `live_body_sha256: f27326e8b13d1dec…` with
`evidence.observed_at 2026-10-08T17:12:59.458Z` against the collector's own **3600 s**
threshold. The deployed renderer at `--as-of 2026-10-14T16:00:00.000Z` emits
`held copy <span style="color:#22c55e">match</span> (pinned vs live)` beside
`as of 2026-10-08T17:12:59.458Z · 5d 22h 47m ago · not re-checked since` while its own
verdict pill reads **`0 green / 6 not green`** — green `match`, its own disclaimer, and
`0 green` in one page, on a pin measured false today. `helm-render.py:323` and `:326`
read the frozen field; `:327-329` builds the qualifier at render. The deployed page
(9,865 B / `427b7b54c69b18d2…` / mtime 2026-10-11T08:57:14.017Z) carries neither — G10's
row, still red — so **the defect measured here is the one a re-render would publish**.
**The fix, one edit.** `q59/patch_render_r29.py` copies the deployed renderer
byte-for-byte (digest asserted before the edit; the plain copy is kept for the
discriminator) and makes the pill's colour and label a function of `site_fresh`:
fresh → green `match`; stale → `#f59e0b` `match (unverified)`; drift → red `drift`.
Fixed renderer `q59/helm-render-g11.py` **22,735 B / sha256
`1e82a1818c57cc9796855ac8ab9de006a3647748596126482ced5df3b5ad3f7a`** (+969 B / +16 lines
on 21,766 B / `5c67473d89283c3d…`). Asserted by the patcher: the anchor occurs once,
`compile()` before any write, trailing newline survives, and `SNAPSHOT`, `OUT_DEFAULT`,
`if is_prod and not deploy:` and `STATE_COLORS["STALE"]` each occur exactly once
afterwards — the destination gate and the snapshot binding are untouched. The emitted
bytes: stale branch 11,806 → **11,819 B** (`3f48643d8e7bac77…` →
**`951a8a7645fe7ef4…`**), the +13 B being exactly one span, first differing character at
offset 8910, `>match<` → `>match (unverified)<`; fresh branch **byte-identical** at
11,624 B / `1eec213e9e363d36…` on both renderers, so the legitimate case is untouched.

contract on **real data** through the fixed renderer's own CLI at a pinned stale clock —
the unqualified green match absent, the amber marked pill present; (2) the fresh branch
not over-refused; (3) the **discriminator at renderer level** — the unpatched renderer,
same snapshot, same pinned clock, still prints the unqualified green match, so rows 1–2
measure the edit and not the clock; (4) a **four-object read-only census** (page,
snapshot, pin, renderer) around all three legs — four rather than G10's one, because the
renderer reads three of them.
**The matrix, prediction stated before the run and met exactly.**

The one shipped failure is G10's deployed-page row, unchanged. The twin

shipped gate (line 2888, `_g11_renderer` repointed at the plain copy) and its row-1
failure names the unpatched output: `rc=0 out_bytes=11806 out_sha256=3f48643d8e7bac77

on the artifact it exists to check. The two shipped stdouts differ on **4 lines**, all
per-run `mkdtemp` tokens, and after normalising the three shapes present they are
byte-identical at sha256 **`ea12512ef4f653ab85d75d64d626cace849fac3e0313ad4c6a0466b08aa95a16`**,

G11 is in production**. Sandboxes **0/0 both ways** before and after each invocation.
Disk **45 G free of 154 (72 %)**.
**Limits, stated:** the renderer still cannot re-fetch, so the fix marks a stale reading
*unverified* rather than re-measuring it — the pill's honesty is bounded by the
collector's clock, and only a re-collect can make the claim current again. The frozen
`manifest_match: true` in the snapshot is still wrong about today and no renderer can
correct a field. The deployed page is still the old generation, so G10's red row is
unchanged and the public page still carries neither the qualifier nor the conditioned
pill.
**One defect of mine, logged first:** `run_gate_q59.py`'s stdout normalisation used two
of the three `mkdtemp` shapes present and reported
`stdout_identical_after_sandbox_normalisation: false` with sha `d9adcf2b…`; the missed
shape was `/tmp/q31-g8-deploy-*`. Corrected in `final_r29.py`, which re-writes the two
fields in `out/R29-GATE.json` and records the correction beside them — **true**,
`ea12512ef4f653ab…`, residual 0. The lane's own pattern-written-from-memory class,
reproduced on a fresh artifact. Nothing else; no figure, digest, count or verdict in the
record depends on it.
### Blocked
Nothing blocks the lane. The standing human gates are unchanged and none is new: the
**§4 adoption `cp` — now collector `4e45021d…` + gate `125754b270bf…`, with the renderer
`1e82a1818c57…` required before any re-render** (superseding `3b98b62fa5c7…` /
`c56230e5a075…` / `cd43284ff009…` / `78b290ecf2d9…` / `e4967da9…` / `a951dbe8…`), the
**`manifest_match` pin** (stale, and now measured false against the live body), the **Q13
publication call** (item 13's decided note controls over its `proposed_action`), **Q9's
checksum handover**, **Q19's onboarding**. Q42 is zephyrus-sparkborn's, Q52 Mercury's,
Q53 the career lane's. Nothing deployed this run: `grep -c HELM_COLLECTOR
/root/.helm/bin/helm-selftest.py` = **0**, so Q40 stands.
### Next
1. **The pipe's verification of this run**, when it lands. Everything re-runs from
`/root/crucible/q59/`: `measure_r29.py`, `patch_render_r29.py`, `make_gate_q59.py`,
`make_twin_q59.py`, `run_gate_q59.py`, `final_r29.py`, `diffcheck.py`,
`normstdout.py` and `tailcheck.py` are self-contained; `out/` holds
`R29-MEASURE.json`, `R29-GATE.json`, `R29-FINAL.json`, the three invocations' stdout
and stderr and the four renders (host-local — the repo carries 0 paths under `out/`,
E13's rule).
2. **No new item opened.** The Helm executable set is empty apart from this lane's own
measured residual; the next Helm unit is the adoption sequence, not a task.
### Ask
Alexander's, unchanged in substance and now a sequence: **(a)** adopt the renderer
`1e82a1818c57cc9796855ac8ab9de006a3647748596126482ced5df3b5ad3f7a` (22,735 B) into
`/root/.helm/bin/`, **then** the §4 `cp` of collector `4e45021d…` + gate
`125754b270bf6b0f55911f407fa9c36c6161b45a71e646fa36a70db096d7de93` (161,122 B / 3,053
lines / 135 registrations) — in that order, because a re-render on the current renderer
publishes the internally inconsistent page this run measures; **(b)** the Q13 publication
call. No ask of the pipe: this run returned nothing to the pipe's own queue, and G11's
discriminator is discharged by the twin above.
