fix(secrets): whitespace-only secrets from 1Password are readable #35936
A successful op read or op inject returning only whitespace (for example a single-space password) was reported as unreadable because six places treated value.trim() === "" as missing: the 1Password driver's nonEmpty, SecretResolver's cache check, SecretCheck (the Settings check), SecretRequests.readReference, settingsSecretValue (resolveSettingsSecrets and requireSettingsSecret) and ProviderInstanceRegistry.readInstanceSecrets (provider env/config references). Each now treats only undefined or "" as unreadable and passes whitespace through verbatim. The issue named four of these; settingsSecretValue and ProviderInstanceRegistry had the same rule, and without them provider env references to a whitespace secret would still count as missing. The 1Password driver is the only secret driver, so no other driver relied on the trim to discard blank output. The empty-secret guard (no fallback to an inherited credential) still holds for truly empty values; the existing registry test case labelled "empty" used " " as its fixture and now uses "". Literal secrets typed in settings (#31690) are untouched. The repro tests from factory/repro-35927 are kept and pass; I did not rerun them on the unfixed code myself and relied on the failure recorded in that branch. No new regex or parser.
Fixes pingdotgg/t3code#35927
Reproduction on main
Commit afff0d3efe (origin/main). After vp i, ran a scratch script from packages/secret-provider-onepassword that imports the production 1Password driver (src/server/driver.ts), provides NodeServices + NodeCrypto (real process spawner), and puts a fake op on PATH that answers read --no-newline and inject -i from a fixture map. Output: single and batch reads of ' ' and '\t\r\n ' both returned undefined; the control ' \tvalue \r\n' was returned verbatim in both modes. Then added two assertions to the existing packages/secret-provider-onepassword/src/server/driver.test.ts (a new single-read case answering ' ', and a ' \t' entry in the existing batch case); vp test run fails both with expected [ undefined ] to deeply equal [ ' ' ] and expected [ 'sk-a', ' sk-b\n', undefined ] to deeply equal [ ..., ' \t' ]. Pushed as factory/repro-35927 (cc245e67de).
Evidence
Configure a synthetic 1Password source, add a sensitive provider variable referencing a password whose value is exactly one space, and run its Settings reference check. Both sides use fresh data, Chromium at 1280×800, light theme, and the same fixture and browser steps.

Scenario and fixture driver · Launcher patch
Not shown:
- Batch op inject, mixed-whitespace values, and exact bytes delivered to a running provider were not exercised; the captured proof covers the single-space Settings reference check.
- Other changed consumers, including settings-secret and secret-request flows, were not separately exercised.
Tests
vp test run packages/secret-provider-onepassword/src/server/driver.test.ts packages/secret-provider-core apps/server/src/secrets apps/server/src/provider/ProviderInstanceRegistry.test.ts: 68/68 pass (first run, before the fixture change: 1 failure in the ProviderInstanceRegistry 'empty' case, which used " " and was changed to ""). vp run check:changed: format, lint, knip, graphql, typecheck (12 packages) and tests (6 files, 69 tests) all pass.
Not in this change
- The batch
op injectpath still rejects a run whose text after the last separator is not whitespace (driver.ts trailing check); that is correct protocol validation and was left alone. - #31690 (a whitespace-only secret typed into the secret card) is a separate, literal-value path and was not changed.

Approvability
Verdict: Needs Human Approval
Macroscope's review found this PR requires human approval — The change preserves whitespace-only secrets across 1Password reads and downstream resolution. An unresolved concern identifies credential fallback that can silently run Cursor or source-control operations under a different account; that account-selection behavior needs resolution.
Needs human approval because:

Each change replaces thetrim()emptiness check with an exact-empty check, or supports tests for that check. The batchop injecttrailing-content check (trailing.trim()) remains. It is protocol validation, not secret value handling, and the PR description says it is intentionally unchanged.

Full details: Description check
-
Explanation
The description follows the repository template closely. It has the Problem, Change, Scope, and Verification content, and it links the issue (pingdotgg/t3code#35927) and states the scope. It explains the root cause (six places treated whitespace-only values as missing), the fix (only undefined or empty string are unreadable), the excluded literal-secret path (
#31690), and the reasoning for keeping the empty-secret guard. Verification includes a reproduction on main, before/after evidence, and the test and check:changed results. It also names what was not checked: batch op inject with mixed whitespace, exact bytes delivered to a running provider, and the unfixed-code rerun of the repro tests. It names the model and harness used, as the template asks. The Title is not part of the description check. The main gaps are minor. The author did not rerun the repro tests against unfixed code, and the evidence links are external and not verifiable from the PR text alone. These gaps do not make the description largely incomplete.

Explanation
Linked issue
#35927has four coding objectives. (1) Individual and batch 1Password reads preserve nonempty whitespace-only values: PASS. In driver.ts,nonEmptynow testsvalue.length > 0.readOneand the batch path (values.map(nonEmpty)) both use it. Onlyundefinedand""returnundefined. (2) Settings checks and provider-reference answers accept those values: the code changes in SecretCheck.ts, SecretRequests.readReference, settingsSecretValue.ts (resolveSettingsSecrets and requireSettingsSecret), ProviderInstanceRegistry.readInstanceSecrets and SecretResolver.read all apply the exact-empty check. The implementation appears complete. (3) Coverage for whitespace-only values across both read paths and affected checks: the driver tests add a whitespace single-read case and a batch entry with ' \t'. The registry test changes its "empty" fixture from " " to "", which removes whitespace coverage there. No test change is listed for SecretCheck, SecretRequests or settingsSecretValue. Coverage for those affected checks is therefore not established. (4) Existing whitespace and multiline behavior is retained: the batch multiline case remains in the driver test. Objective (3) is unmet for the affected checks.Resolution
Add tests that pass whitespace-only values (for example ' ' and ' \t') through the affected checks: SecretCheck.check (the Settings check), SecretRequests.readReference, and settingsSecretValue (resolveSettingsSecrets and requireSettingsSecret). Assert that each returns the value verbatim and does not return a Failed or missing result. Keep a test that confirms an exactly empty value is still unreadable. Optionally restore a whitespace-only case in the ProviderInstanceRegistry test in addition to the "" empty case.
