fix(cli): reject a SECRET that cannot be saved to .env and read back unchanged - #1091
nostream setup took a SECRET from the environment and wrote it to .env unquoted. Node's loader, which the CLI starts the relay with (--env-file), reads an unquoted # as the start of a comment, so a secret like my-secret#suffix came back as my-secret. setup --start ran the relay with the full value and every later start with the truncated one, so the relay's derived keys changed between the two.
The checks the interactive prompt already had (no #, no newline) now live in one helper, getUnsafeSecretReason, and also cover a $, which Docker Compose reads from the same .env and expands ($NAME, ${NAME}, $$) while Node's loader does not, and a quote that does not match, which the loader would read differently. It is applied in three places:
resolveSecret throws on an inherited SECRET that fails it, with a message that says what is wrong and to unset it or use another one, instead of saving a value that will not read back;
the prompt validator uses it, so it refuses the same values, and a quoted answer typed at the prompt is saved without its quotes, as an inherited one is;
upsertSecret refuses to write a secret that fails it, as a last guard.
A secret the CLI accepts has to be the secret the relay runs with on every start. Rejecting follows the first of the two fixes proposed in the issue and matches what the prompt already did; values with =, !, spaces or a single apostrophe are unaffected, and a secret wrapped in matching quotes is still accepted. A $ is rejected rather than quoted because the two loaders agree on a single-quoted value but not on every other form, and a hex secret (the recommended kind) has none.
How Has This Been Tested?
New tests: an inherited SECRET with #, a newline, or an unmatched " or ' is rejected with the reason and .env is unchanged; a secret handed back by the prompt with a # is rejected before it is written; the prompt validator refuses an unmatched quote and accepts a quoted secret; several accepted secrets (a=b, it's-fine, spaces, trailing ==, matching quotes) are written and read back from .env as the same value with Node's own util.parseEnv, and again through setup's own parser with nothing inherited; a quoted answer typed at the prompt is saved without its quotes; secrets with $NAME, ${NAME}, $$ or a lone $ are refused.
Removing the inherited-secret check, the upsertSecret guard, the quote rule, the $ rule or the unquoting of the prompt answer each fails a test.
The setup spec now runs against src/ instead of dist/, so its coverage counts in the unit coverage report (it was about 7% for setup.ts and is now about 85%).
pnpm lint, pnpm check:deps, pnpm run build:check, pnpm run verify:cli:build, pnpm run test:cli (128), pnpm run test:unit (3004).

Bug Fixes
CLI setup now rejects secrets containing #, newlines, $, or unmatched quotes that cannot be saved to .env and read back unchanged.
When an inherited secret is rejected, setup recommends unsetting it and leaves the existing .env file unchanged.
Balanced outer quotes are removed from accepted input. Supported values containing spaces, equals signs, or apostrophes remain consistent across setup runs.
Setting an unsafe SECRET through the configuration command now reports the issue and leaves .env unchanged.
The CLI rejects inherited and prompted SECRET values that cannot be saved to .env and read back unchanged. Tests cover unsafe values, quote handling, and accepted-value round trips.
Changes: SECRET round-trip validation
Layer / File(s)
Summary
SECRET validation in setup and config src/cli/utils/env-config.ts, src/cli/commands/setup.ts, src/cli/commands/config.ts
Shared checks reject secrets containing #, carriage returns or newlines, $, or unsafe quote patterns. Setup applies the checks to inherited values, prompted values, and values passed to upsertSecret. Prompted values have matching surrounding quotes stripped before use. Config rejects unsafe SECRET values before saving them.
Round-trip tests and patch changeset test/unit/cli/setup.spec.ts, test/unit/cli/commands.spec.ts, .changeset/cli-secret-hash-roundtrip.md
Tests cover rejection without changing .env, quote handling, validation cases, and accepted values parsed across setup runs. A patch changeset describes the CLI fix.
cameri/nostream#1058: Added inherited and prompted SECRET validation in setup.ts; this change adds checks for more unsafe values and quote handling.
cameri/nostream#1055: Released setup secret validation from PR #1058; this change extends the same setup behavior.
Merge Risk: Moderate · up to c3065
Setting a quoted SECRET that contains a backslash escape such as \n can make setup and later starts use different signing keys. Reject or normalize such values before merging. The earlier quoted-truncation case is now rejected.
Security architecture risk: Low · up to c3065
The change strengthens safeguards against secrets changing after restart. No new privilege or externally reachable access was established. Some pre-existing round-trip and failure-recovery limitations remain, and end-to-end loader behavior was not fully verified.
Retained concerns
No architecture-level concerns identified.
Security review details
Security Blast Radius
inferred — The demonstrated input authority is control over local CLI arguments, the inherited environment, or project configuration. The affected scope is the relay deployment consuming that project's SECRET; no new remote input path, cross-tenant reach, or privilege expansion was established.
Trust Boundaries and Controls
observed — For config-set, general validation and the SECRET-specific check execute before the filesystem writer. Setup checks inherited or prompted inputs and checks again inside upsertSecret before the write is evaluated. These controls reduce unsafe persistence without granting additional authority.
Resilience and Maintainability Implications
inferred — Acceptance by the shared helper does not establish identical representation across every loader. Config-set still retains surrounding quotes and literal escape sequences, whereas setup removes matching quotes. The same raw config-set persistence existed at the base, so this residual identity risk is not treated as an introduced concern.
Hardening Proposals
proposed — As follow-up hardening, define one canonical SECRET representation for both writers and verify it against both supported loaders. Treat file initialization, secret persistence, and process-environment activation as one recoverable transition so refusal or write failure cannot leave partially activated configuration.

Explanation
[#1060] The rejection implementation meets the main behavior. resolveSecret and upsertSecret reject inherited #, newline, and unmatched-quote values before .env is written. The tests verify clear errors and unchanged .env content. The required round-trip test is incomplete. The accepted-value tests use Node util.parseEnv and a later setup run, but they do not invoke Node with --env-file or directly assert the readEnvSecret path for the value written by upsertSecret.
Resolution
Add a test that writes an accepted value through setup or upsertSecret, asserts the value through the setup readEnvSecret path, and loads the resulting .env with Node's --env-file. Assert that both values equal the original secret.

A rabbit checks the secret at the door, No hash or newline slips through anymore. Quotes come off when they match just right, Safe values return from the file in sight. The burrow keeps its settings tight.
The accepted-value cases do not check readEnvSecret on the saved values. A regression that truncates a=b can pass these tests. Clear the inherited secret and rerun setup to check the saved value.

1) In the prompt branch of resolveSecret, return stripQuotes(trimmed) for a
matching-quote input, or reject quoted input with a clear message. Then
process.env.SECRET equals the value that .env holds. 2) Add a test that enters
"quoted-secret" through the prompt and asserts that process.env.SECRET equals
parseEnv(readEnv()).SECRET. 3) Add a round-trip assertion that reads the written
.env through readEnvSecret. This can use a second runSetup call or an exported
test hook.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
Validate an existing .env SECRET before accepting it.
If .env already contains SECRET=pre$TOKEN, ensureEnvFile returns here without calling getUnsafeSecretReason. Setup reports success, but a subsequent Docker Compose start can interpolate the stored value into a different relay signing key. Apply the check on this read path as well, especially for files created before this change. (raw.githubusercontent.com)

Reject quoted SECRET values that lose content on read-back.
config env set SECRET '"abc"tail"' succeeds and writes the original value. Node and setup then read only abc, so a later start can use a different SECRET.
Validate the value that config env set writes against the loader’s read-back value, or normalize it safely before writing.

Safe quoted secrets are refused
getUnsafeSecretReason now rejects an inner quote that matches the outer quotes, even when setup would remove the outer quotes before saving. For example, a prompted or inherited 'it's-fine' previously became it's-fine and read back unchanged, but now setup refuses it. Users must remove the outer quotes to proceed.
Apply this check to the value each caller actually writes: setup removes the outer quotes, while config env set keeps them.

Reject or normalize quoted escape sequences before saving.
SECRET value "abc\ndef" passes this check and is saved with its quotes. Node expands \n to a newline, but the setup parser reads a literal backslash and n. Starts through those paths can therefore use different secrets and derived keys. Validate the serialized value against both readers, or normalize it before saving. (raw.githubusercontent.com)
