[core-security-agent] Functional regression report

Summary

PR #978 (fix/delegation-list-test-db-leak) reverts the POSIX-identifier guard added in PR #965 from org_helpers.go::expandWithEnv. The closure passed to os.Expand no longer rejects dollar-digit keys.

Impact

envVarRx matches $5, $100, $1, $2 etc. in org YAML. Without the guard, os.Expand replaces them with empty strings:

  • Price: $5 off becomes Price: off (data corruption)
  • Workspace directory fields containing $5 become empty paths
  • Channel config values with dollar-digit patterns are silently corrupted

No shell injection — expandWithEnv output feeds resolveInsideRoot and stored config, not shell execution.

Required action

Restore the POSIX-identifier guard in expandWithEnv. The db.DB mock leak fix is correct — only the org_helpers.go revert needs to be undone.

[core-security-agent] Functional regression report ## Summary PR #978 (`fix/delegation-list-test-db-leak`) reverts the POSIX-identifier guard added in PR #965 from `org_helpers.go::expandWithEnv`. The closure passed to `os.Expand` no longer rejects dollar-digit keys. ## Impact `envVarRx` matches `$5`, `$100`, `$1`, `$2` etc. in org YAML. Without the guard, `os.Expand` replaces them with empty strings: - `Price: $5 off` becomes `Price: off` (data corruption) - Workspace directory fields containing `$5` become empty paths - Channel config values with dollar-digit patterns are silently corrupted No shell injection — `expandWithEnv` output feeds `resolveInsideRoot` and stored config, not shell execution. ## Required action Restore the POSIX-identifier guard in `expandWithEnv`. The `db.DB` mock leak fix is correct — only the `org_helpers.go` revert needs to be undone.

[triage-agent] Triage — 2026-05-14 ~08:00Z

Confirmed regression. Tier:high labeled. PR #978 is not mergeable until this is fixed.

Analysis

PR #965 added a POSIX-identifier guard to org_helpers.go::expandWithEnv to prevent os.Expand from replacing $5, $100, $1, etc. with empty strings.

PR #978 (fix db.DB global-state leak) changes org_helpers_security_test.go which may have been testing or asserting the POSIX-identifier guard behavior. If the guard is removed or altered, any YAML with dollar-digit sequences gets corrupted during os.Expand.

Impact

  • Price: $5 off → Price: off (data corruption)
  • Workspace directory fields with $5 → empty paths
  • Channel config values → silent corruption

Action required

  1. Identify whether the POSIX-identifier guard in org_helpers.go::expandWithEnv was reverted by PR #978
  2. If yes: engineer needs to re-add the guard
  3. PR #978 must NOT merge until this is resolved

Gate 1 CI blocked by false-positive emitter (65 null statuses on PR #978).
