# Firebird Mission 00E Task 4 Report

## Verdict

`MISSION_00_BLOCKED` remains the live-discovery result carried forward from the
prior credential-gated run; this report also records Mission 00E Task 4 boundary
hardening.

The live gate stopped before driver import or database access because the
required process-environment credentials `FB_USER` and `FB_PASSWORD` were not
available. No credentials were guessed or read from external ERP files.

## Boundary

- Authorized target: authorized-database label only
- Other databases accessed: `0`
- Application DDL/DML writes: `0`
- ERP files modified: `0`
- Client library loading: not reached
- Engine identity check: not reached
- Catalog collection and safe sampling: not reached
- Procedures/triggers: not executed or inspected live
- BLOB/image data: not read
- Real fingerprint: not generated; classification is `SCHEMA_UNKNOWN`

## Threat model

The boundary protects against implementation mistakes, accidental unauthorized operations,
arbitrary SQL exposed to normal callers, the wrong database,
writes, procedures/UDFs, injection, and dependency shadowing. `TRUSTED_PROCESS
= TRUE`: arbitrary Python already running in the same process, including
deliberate introspection or monkey patching, is outside scope. No artificial
cryptographic controls are added.

## Blocker

`credentials_unavailable`

The probe emitted the blocker without exposing exception text or secret
values. Continue only after `FB_USER` and `FB_PASSWORD` are supplied through
the process environment, using the same authorized database label.

## Verification

The complete offline test suite, diff check, Git status, and Git identity check
were run after this report was written; results are recorded in the task
completion response.

## Git State

`GIT_IDENTITY_NOT_CONFIGURED`. No Git identity was configured and no Git
configuration was modified.
