P2 — Cloud Agent install uses unhashed pip install -r requirements.txt. CI and the Dockerfile require --require-hashes -r requirements-hashes.txt. This weakens the baked environment supply chain.

Fix: python -m pip install --require-hashes -r requirements-hashes.txt (already on #1381).

🧩 Analysis chain

🌐 Web query:

PostgreSQL psql documentation: verify that --set=name=valuewith:'name'safely substitutes a SQL string literal in a-c command.

💡 Result:

The use of --set (or -v) variable substitution within the --command (-c) flag of psql is not supported and will not work as expected [1][2][3]. The -c option requires the command string to be completely parsable by the PostgreSQL server, meaning it cannot contain psql-specific features like variable substitution (:name or:'name') [3]. Regarding the safety of:'name' for SQL string literals: while:'name' performs client-side substitution by wrapping the variable's value in single quotes and escaping it, this is a psql-specific feature that only operates during script or standard input processing [1][2][4]. Because -c does not trigger this substitution mechanism, attempting to use:name or:'name' inside -c will result in a syntax error from the database server [2][3]. To use variable substitution safely: 1. Do not use the -c option. 2. Instead, pipe the command into psql (e.g., using echo or a heredoc) or use the -f option to read from a file [1][2][4]. 3. Use the:'name' syntax within your SQL script or piped command to ensure the value is correctly quoted and escaped for use as a SQL string literal [4]. Example of the safe, recommended pattern: psql -v myvar="safe_value" <<< "SELECT * FROM my_table WHERE col =:'myvar';" [4]

Citations:

🌐 Web query:

site:postgresql.org/docs/current/app-psql.html psql -c variable substitution --set :'name'

💡 Result:

In psql, the colon (:) prefix is used for variable interpolation, not for defining variables [1]. When you use the --set flag on the command line (e.g., psql --set=name=value), you are assigning a value to a variable named name [1]. You do not include the colon in the variable name when defining it via --set. Once defined, you use the colon to substitute the variable's value within your SQL queries or psql commands. For example: 1. Define the variable on the command line: psql --set=my_var='Hello' 2. Use the variable inside psql: SELECT:'my_var'; The colon instructs psql to replace:my_var with the value of the variable my_var. The syntax:'variable_name' is specifically used to interpolate the variable's value suitably quoted as a string literal, which helps prevent SQL injection and handles special characters safely [1]. If you use the syntax:name (without quotes), psql performs a simple substitution of the variable's value. If you use:'name', psql treats the result as a SQL string literal [1]. The documentation also supports the form:"name" for identifier quoting.

🌐 Web query:

site:postgresql.org/docs/current/app-psql.html "-c command" "variable substitution" psql

💡 Result:

The current PostgreSQL psql documentation states:

  • -c command accepts either a server-parsable SQL string or one psql backslash command; SQL and meta-commands cannot be mixed in a single -c argument.
  • psql variable substitution applies to SQL and meta-command arguments, using syntax such as :variable, :'variable', and :"variable".
  • Therefore, use separate -c options when combining them:
psql -v foo=my_table -c '\set bar :foo' -c 'SELECT * FROM :bar;'

Reject invalid passwords and use psql variable binding.

If $HOME/.env lacks DATABASE_URL or contains an empty password, the script sets the postgres role password to an empty value. Reject a missing or empty password before running ALTER USER.

A single quote in DB_PASSWORD can terminate the interpolated SQL literal and inject SQL executed as postgres. Use --set=db_password="$DB_PASSWORD" and :'db_password' instead.

P1 — ALTER USER postgres WITH PASSWORD '${DB_PASSWORD}' interpolates the role secret into SQL and leaves it on the psql -c argv. First-boot token_urlsafe is quote-safe; a pre-existing ~/.env (the same file naruon_compose.sh prefers) is not. Empty passwords also proceed.

psql -c does not expand :'var' (PostgreSQL Global Development Group, n.d., psql). Pass the secret on stdin as dollar-quoted SQL, reject an empty secret, and keep it off argv. #1381 does this in scripts/reconcile_local_postgres_role.py.

Preserve pre-existing emails.is_read during downgrade.

Line 28 and Line 29 allow upgrade() to skip a column that already exists. Lines 46 through 48 then drop any present is_read column, including one that this revision did not create. A rollback can remove read-state data from a legacy database.

Make column ownership explicit, or make this retired-table reconciliation downgrade a safe no-op. Do not infer ownership from current column presence.

P2 — Downgrade drops emails.is_read whenever the column is present, including when this revision skipped upgrade because the column already existed. Make downgrade a documented no-op for the retired table. #1381 does that.

This revision still never mutates email_records. Add a guarded follow-up revision (0018 on #1381) for email_records.is_read NOT NULL DEFAULT true.

Add an Alembic migration for email_records.is_read.

No migration creates or alters email_records.is_read: 0011_email_read_state only targets emails, and 0014_merge_email_read_state is a no-op. Existing databases can therefore retain NOT NULL without DEFAULT true, causing raw inserts that omit is_read to fail. Add a guarded migration and a focused existing-schema insert test.

In `@backend/db/models.py` around lines 807 - 812, The model change to
email_records.is_read needs a corresponding Alembic migration. Add a guarded
migration that creates or updates email_records.is_read with NOT NULL and
DEFAULT true for existing schemas, and add a focused test proving inserts that
omit is_read succeed and receive true; keep the migration safe when the column
already exists.

Use an independent expected value for the lock-key contract.

expected_owner_key is computed with _owner_import_quota_lock_key, the same helper used by the production request. The assertions therefore prove only that the request path calls the helper and that its output contains no NUL. They do not detect a wrong delimiter, omitted owner component, or changed hash algorithm. Add a focused helper test with a fixed known digest or an independently implemented reference, and keep these endpoint assertions for acquire/release parameter wiring.

As per coding guidelines, backend/tests/**/* requires focused contract tests for changed behavior.

P3 — The expected lock key is derived from the production helper, so a rewrite of _owner_import_quota_lock_key cannot fail this test. Keep the route-wiring asserts, and add an independent hashlib.sha256(b"testuser\\x00org-acme").hexdigest() golden (3fbc5671f32a1608f88c1775c1008c26c53faaea0308b97c556eeceb2b4bb8d3). #1381 adds tests/test_email_import_quota_lock_key.py.
