backup.sh says it outright -- it verifies the artefact, only a restore verifies
the backup -- and its header names this script as the missing half, with the
pg_restore command it should run. This is that command with the parts that stop
it being dangerous.
A dump pg_restore --list can read is a file with a table of contents, not a
database. Between those sit every reason a restore fails on the day it is
needed: a missing extension, an owner that does not exist, version skew, a dump
of the wrong database that reads perfectly. And the number nobody has and will
want badly: how long it takes. During an incident that decides whether you
restore or fail over, and it is unknowable from the file size. Printed every run.
**The dangerous part.** pg_restore --clean issues DROPs, and pointed at
production it obeys immediately and irreversibly. Handled by never accepting a
target: there is no --database flag, because naming the database is the mistake.
The script creates `restorecheck_<epoch>_<pid>`, restores into that, and drops it
from a trap so an interrupted run leaves no copy of production data behind.
Same argument status.sh makes for having no --host flag.
Shares BACKUP_DIR, BACKUP_NAME and BACKUP_MIN_TABLES with backup.sh rather than
taking its own, so the two cannot disagree about which series belongs to this
project.
Proved against a real PostgreSQL, not asserted -- GUARDS.md section 1:
exit 0 a real 3-table dump, minimum 1
exit 1 minimum raised to 99; a dump truncated to 2000 bytes; a zero-byte dump
exit 2 unconfigured (naming the missing value one at a time); server
unreachable
exit 0 --dry-run, always, contacting nothing
Two things that testing found and assertion would not. Every scratch database
was dropped, confirmed by querying pg_database afterwards. And --dry-run could
exit 1 on an empty dump, because the emptiness check ran before it; a mode whose
exit code depends on the state of the data is not a dry run, so the check moved
below and the dry run now notes the emptiness in its plan instead.

Review trigger: Any new module, any change to a module boundary or a data shape
What belongs here
How the thing is built, for somebody who has to change it:
- Module boundaries — what each part owns, and what it is not allowed to know about. The boundaries are the architecture; everything else is detail.
- Data shapes — the structures that outlive a single function, especially anything persisted or sent over a wire.
- Reference manuals — the long documents that answer "how does X work" without requiring a full read of X.
- Decisions with consequences — why this database, why this concurrency model, why this dependency. Include the option that was rejected and what it would have cost, because that is the part nobody can reconstruct later.
Documents here
GUARDS.md— how to write a check that actually checks. Read it before adding a structural test or a probe; every rule in it was learned from a guard that had been green over something broken.
What ships in this folder
Working code, not just prose. Copy what a project needs and delete the rest — these are a starting point with the arguments already made, not a framework.
This table is the one copy of that list. docs/TOOLS.md is the
signpost every project is expected to have — it points here rather than
repeating it, and answers the two questions this table does not: which scripts
can stop you, and where to start in a fresh clone.
| Path | What it is |
|---|---|
scripts/release.sh |
version bump, guards, build, verify, push, prune. Refuses to build on a half-run test suite or a malformed public origin. |
scripts/verify.sh |
the repo's own checks, in one command |
scripts/check-env.sh |
which variables are set, which are missing, before anything reads them |
scripts/migrate.sh |
apply and report migrations, including the ones that run outside a transaction |
scripts/backup.sh |
a dump that is verified before it is trusted |
scripts/restore-check.sh |
the other half of backup.sh: restores the newest dump into a scratch database it creates and drops, counts the tables, and times it — the number an incident actually needs. Never accepts a target, because naming one is the mistake --clean punishes. |
scripts/healthcheck.sh |
a liveness tick with the URL written down rather than re-derived each run |
scripts/status.sh |
what is deployed, and whether it matches this checkout |
scripts/dev.sh |
bring the local stack up |
scripts/scaffold.sh |
lay out a new project in this shape |
scripts/doc-triggers.py |
which documents a pending change fires, read from their Governs: headers. The Review trigger on each document names the change that should send somebody back to it; this is the check that asks before the commit rather than after |
scripts/prove-guard.sh |
breaks the thing a guard protects, requires the guard to go red, restores the file from a trap. GUARDS.md §1 written out as a command, including the count — one failing test reported on six lines is not six failures |
scripts/commit-mine.sh |
commits only the paths you name, by pathspec, after the secret scan. For a tree something else is also writing: what anyone else has staged is reported and left exactly as it was |
scripts/doc-claims.sh |
every file a document names must exist, and (--covers) every file that exists is named — the second is the one that catches a list missing rows |
scripts/duplication.py |
code that exists twice, tuned so what it reports is worth reading |
scripts/dead-code.py |
exports nothing imports, and assets nothing renders |
scripts/secrets.sh |
credential shapes in a staged diff, using the project's own patterns where it has them |
scripts/audit-gate.mjs |
high/critical advisories in production dependencies, with the allowlist npm does not have. An entry must say why the advisory cannot reach this app, what would make it reachable, and what retires the entry — three fields, so a waiver stays falsifiable. Exits 2 when nothing was checked. |
scripts/forgejo-issue.py |
file and close issues in the tracker convention, with every rule of it as a check |
scripts/deploy.py |
update the running stack to a published image. Publishing and deploying are separate; this is the second one. The only copy — it existed twice and drifted (#209); the privacyllc-deploy skill's is now a symlink to this file. Identity-free by design: it reads DEPLOY_IMAGE, DEPLOY_STACK_ID, DEPLOY_CONTAINER and DEPLOY_SITE_URL from the environment and refuses to run without them, so each project supplies its own via a wrapper. Never hard-code one here — least of all the site URL, which is frozen into the image at build time. |
scripts/release-notes.mjs |
tags the release and writes its notes, grouped by the commit types the message hook already enforces. Runs after release.sh has published, so a failure here cannot cost an image. Scrubs credential shapes out of commit subjects first — the body goes to a public repository. |
githooks/ |
pre-commit, commit-msg, post-commit — see its README for the one install command |
Every script takes its configuration from the environment and hard-codes nothing
about any particular deployment. check-env.sh is the one to run first.
What does not belong here
- Product intent — that is
docs/planning/PROJECT_PLAN.md - What it should feel like — that is
docs/design/ - What happened while building it — that is a history log, not architecture
A note on drift
Architecture docs go stale faster than any other kind, because code changes under them silently. This is exactly what the Review trigger line is for: name the change that should send somebody back here, and a reader can tell whether the trigger has fired.
