papra mounted papra_data:/app/data while the application writes to
/app/app-data, so its database sat in the container's writable layer: lost on
redeploy, and tarred nightly as an empty directory while the healthcheck stayed
green. Last of the three apps R-156 convicted.
Decided from the IMAGE, not the README. docker inspect of
ghcr.io/papra-hq/papra:26.6.1-rootless gives WORKDIR=/app and all three data
paths under ./app-data (DATABASE_URL, DOCUMENT_STORAGE_FILESYSTEM_ROOT,
PAPRA_CONFIG_DIR) — and /app/data does not exist in the image at all.
Reconfiguring the app to write to /app/data was available and deliberately not
taken: it enumerates data paths, so a fourth added upstream would escape to the
writable layer again, silently — this defect re-armed. Mounting the app's own
data ROOT captures every current and future path by construction.
Precondition checked rather than inherited: docker ps -a (including stopped) on
BOTH demo guests, plus the hub fleet view (two enrolled hosts, zero papra) —
both boxes were wiped and rebuilt today, so the 2 August evidence was re-measured.
Proven by the runtime gate in both directions: CLEAN with the self-test passing,
and BROKEN when the mount is reverted, with the exact R-156 evidence. Full
catalog_gates.py papra: all three gates OK.
scripts/catalog_gates.py runs all three gates - image-pins, image-resolvable,
volume-persistence - and exits non-zero if any fails. Mandated in CLAUDE.md the way
felhom.eu/scripts/site_gates.py is: run it after any template change, naming the
app(s) you touched.
Operator ruling, recorded because both alternatives were rejected for measured
reasons. Controller-side enforcement at template load was rejected because such a
check can only read the file, and a static audit of all 53 templates reports the
catalog clean INCLUDING papra - it would pass on the exact defect it exists to
catch; the property is decidable only at runtime. CI was rejected for now: neither
repo has any, and there are no users yet. What was chosen copies the shape that
demonstrably works here - of this project's gates, the only ones that ever get run
are the ones with a single entry point named in a CLAUDE.md; site_gates.py is run,
and R-29's three orphans are named nowhere and have stopped nothing.
Behaviour: 0 all clean / 1 convicted / 2 UNDETERMINED, never a pass; a conviction
outranks an undetermined result so the reader knows which they have. Gate output is
streamed, not captured. App names scope the two gates that accept scoping; with no
names the runtime gate deploys every template and belongs on a scratch host.
Adding a fourth gate means one line in GATES.
R-161 stays OPEN at reduced scope: this is convention, run by a person. Real
automatic enforcement is owed when a second person touches templates.
Verified: image-pins passes standalone (53 templates, 0 unpinned), the
unknown-option path exits 2, and the aggregation was unit-checked over five
gate-code combinations. The runtime leg was deliberately NOT executed - it deploys
templates via docker compose and DooPlex is the recovery chain - so the runner's
end-to-end invocation of that third gate is inferred, not measured, and is flagged
in REPORT.md to be closed on a scratch host at the next campaign.
REPORT.md overwritten per convention; the persistence sweep's report is preserved
at audits/persistence-sweep-2026-08-02/ and pointed to from the new one.
The register grep that put these at R-158..R-161 was true when run and stale within hours: the
parallel session pushed SPIKE-recovery-unit-space-2026-08-02.md and CAMPAIGN-10-closeout-2026-08-02.md
mid-run, both using R-158 for an unrelated finding, and neither files it — ROADMAP.md and
OPEN-ITEMS.md still stop at R-155.
So two sessions minted the same number for different findings on the same day, which is the exact
failure §8.0 was already documenting about R-154/R-155 and R-156/R-157. Now recorded with itself as
the third instance. R-156, R-157 and R-158 are all live in audit documents and none is filed.
Layer 1: guest 9301 destroyed, vm-9301-disk-0 removed, pct list clean.
Layer 2: local-lvm available returned to 258 702 410 KiB — EXACTLY the pre-run baseline (29.27%).
Layer 3: no hub record was ever created (the scratch guest ran no controller and was never
enrolled, by design); confirmed absent from /configs and /hosts after teardown.
papra referral updated: c10-soak was torn down by the other session mid-run and papra disappeared
from hub telemetry with grafana, homebox and rallly — Campaign 10's four discriminator apps (§A4).
So papra's one deployment was on c10-soak. The fix is STILL not applied: that is absence evidence,
demo-hp is fenced, and applying it wrongly is irreversible while leaving it is a one-line push.
The single command that settles it is recorded.
Campaign 10's R-156 found papra writing its database into the container's writable layer while the
volume the template preserves stayed empty — a backup that completes, verifies, and contains
nothing. papra was never the point: nothing anywhere checked that the folder a template preserves
is the folder the app writes to. All 53 templates have now been measured live.
43 CLEAN / 3 BROKEN / 7 UNDETERMINED. UNDETERMINED is counted separately, each with its reason,
and never folded into CLEAN.
FIXED (neither app is deployed anywhere, so nothing was stranded):
- gramps-web mounted /app/data, /app/media, /tmp — and /app/data is a path the application never
writes. Its accounts database and ITS FAMILY TREE both landed in the writable layer while
gramps_data was tarred nightly as an empty directory. Now persists the eight paths the image's
own environment names, matching upstream's reference compose. Proven: users.sqlite and the
family-tree files survive a redeploy byte-identical, same inode.
- wishlist mounted wishlist_data:/data, another path the app never writes; prod.db landed in the
ANONYMOUS volume from the image's VOLUME directive — absent from ResolveDockerVolumeNames, so
never backed up, and orphaned by a redeploy. Now mounts /usr/src/app/data + /usr/src/app/uploads.
Proven: prod.db byte-identical, same inode, across a redeploy.
Every corrected path confirmed by two independent sources — the shipped image's own
environment/Config.Volumes and upstream's reference compose — never inferred from a directory name.
papra is NOT fixed. It is live on one box, and changing the mount target makes the next compose up
recreate the container and destroy the writable layer its documents live in. The fix is prepared
and proven in the scratch guest (current: db.sqlite differs after a redeploy, so a real account
created via the API is lost; fixed: byte-identical, it survives). Referred to the operator with the
two options; no migration written.
NEW GATE scripts/check-volume-persistence.py — the third catalog gate and the only RUNTIME one.
This class is invisible to static analysis, measured not assumed: a static audit of all 53 composes
reports the catalog clean AND reports papra clean. Exit 0 clean / 1 REFUSED / 2 undecided. It
refuses to report at all unless it has just re-proven itself in both directions against two canary
templates that differ only in which path the volume mounts at, so every run carries a live
demonstration of R-156 and of its fix. No docker exec anywhere (Campaign 7 §1.1). 44 fixture tests
driving check(), the function __main__ calls; every rule red-proofed.
Enforcement is convention, not CI — this repo has no CI. Stated plainly in the report; raising it
is proposed as R-160.
Report, per-app evidence, proofs and proposed register entries (R-158..R-161, NOT filed — felhom.eu
is fenced this session): audits/persistence-sweep-2026-08-02/
wanderer: ghcr.io/flomp/wanderer:0.16.0 is a ghost - upstream split the app
into web+db images, moved registry and renamed the org. Restructured to
upstream's own v0.20.0 compose (3 services, new /data/plugins volume, second
public hostname for PocketBase, meilisearch pinned DOWN to upstream's v1.36.0
per the R-42 ruling).
plant-it: retired. The repo name was wrong (plant-it-server) but upstream has
DELETED self-hosting; last server image is 2024-12-10 and it needs MySQL+Redis
the template never had. Moved to retired/ rather than deleted - reversible.
R-41 slice 1: check-image-resolvable.py. Encodes two traps - manifest inspect
exits 0 while printing toomanyrequests, and the inverse, where the first sweep
called 24 of 65 pins dead because Hub throttled it. Ambiguity is INCONCLUSIVE,
never an accusation.
bentopdf :latest -> v2.8.6; calibre-web :latest -> v4.0.6 (== running digest on
demo 9201, c31a738b - pin is a no-op); papra :latest -> 26.6.1-rootless (latest
was the rootless variant); recipe-importer :latest -> v0.9.11 (tag pre-existed,
digest-equal, no retag needed); termix :latest -> 2.5.0.
All five pins digest-identical to what :latest resolved to on 2026-07-12.
New gate scripts/check-image-pins.py (catches floating tags AND untagged refs;
red-proofed both shapes). Standing rule in CLAUDE.md + REUSE.md row.
Vaultwarden treats defined-but-empty SMTP_HOST/SMTP_FROM as "set"; with upstream
_enable_smtp defaulting true its validation errors out and the container
crash-loops on every fresh deploy with app-email off (the default). Gate the
SMTP group with _ENABLE_SMTP: compose default false (clean boot, mail off),
flipped "true" by the app-email injection via smtp_mapping.extra. Proven on the
pinned 1.33.2-alpine image (P1 repro exit 12 / P2 off boots / P3 on boots).
REUSE.md: strict-image TRAP row. Sweep note: the other 5 smtp-mapped templates
are campaign-boot-proven tolerant; no edits.
