# PHASE X4.11-I2 — PHASE 1B — CASHIER IDENTITY & ISOLATION — READ-ONLY AUDIT

Audit timestamp: 2026-10-08T04:00+07:00 Asia/Jakarta (UTC+7)
Auditor mode: READ-ONLY — no files modified, no builds executed, no production contact
Target: `C:\Users\M S I\Documents\PROJECT\POS SATE\android-print-agent-cashier`
Reference (read-only compare): `C:\Users\M S I\Documents\PROJECT\POS SATE\android-print-agent`

Status: **PASS**

---

## 1. Scope and Method

- This phase is strictly evidence collection. No file was created, deleted, renamed, or edited under either `android-print-agent-cashier` or `android-print-agent` except this report.
- No Gradle task was executed. No APK was built or installed. No application was launched, no Bluetooth connection attempted, no print job created, no device token provisioned.
- No PHP/database/migration/route/server file was read or written beyond the two Android projects in scope.
- Command budget respected: well under 30 shell invocations; inspection limited to `android-print-agent-cashier` source/config and spot-check of specific known Kitchen reference files.
- Source-isolation conclusions ignore generated directories `.gradle/`, `build/`, `out/`, `out-bt/` where present. All grep/Select-String scopes were explicitly filtered to exclude `*\build\*` and `*\.gradle\*`.

---

## 2. Application Identity

### 2.1 Application ID

Source: `android-print-agent-cashier/build.gradle:16`
```
applicationId "id.sategajah.printagent.cashier"
```
Generated confirmation (`build/` is evidence only, not source truth):
- `build/generated/source/buildConfig/debug/agent/cashier/BuildConfig.java:8` → `APPLICATION_ID = "id.sategajah.printagent.cashier"`
- `build/outputs/apk/debug/output-metadata.json:7` → `applicationId: id.sategajah.printagent.cashier`
- `build/intermediates/merged_manifests/debug/AndroidManifest.xml:3` → `package="id.sategajah.printagent.cashier"`

Verdict: **PASS** — required value `id.sategajah.printagent.cashier` present as sole applicationId.

Negative check:
- Grep `id.sategajah.printagent` across cashier source (excl. build) → only `id.sategajah.printagent.cashier` (in `build.gradle`). No bare `id.sategajah.printagent` (without `.cashier`) remains in source/config.

### 2.2 Namespace and Package

Source: `android-print-agent-cashier/build.gradle:12`
```
namespace 'agent.cashier'
```

Source: `android-print-agent-cashier/src/main/AndroidManifest.xml:3`
```xml
package="agent.cashier"
```

Source: Android source package
```
src/agent/cashier/BluetoothPrinter.java:1  → package agent.cashier;
src/agent/cashier/BootReceiver.java:1     → package agent.cashier;
src/agent/cashier/FileLog.java:1          → package agent.cashier;
src/agent/cashier/MainActivity.java:1     → package agent.cashier;
src/agent/cashier/PrintAgentService.java:1 → package agent.cashier;
src/agent/cashier/SecureTokenStore.java:1  → package agent.cashier;
```

Core package intentionally generic:
```
src/agent/core/AgentPolicy.java:1          → package agent.core;
src/agent/core/Cp437.java:1               → package agent.core;
src/agent/core/DeviceApiProtocol.java:1   → package agent.core;
src/agent/core/EscPosRenderer.java:1      → package agent.core;
src/agent/core/Json.java:1                → package agent.core;
src/agent/core/PrintPipeline.java:1       → package agent.core;
```

Test package consistency:
```
test/*.java                               → package agent.test; import agent.core.*
test-android/BluetoothPrinterTest.java:1  → package agent.cashier; import agent.cashier.BluetoothPrinter;
test-android/RunBluetoothTests.java:1     → package agent.cashier;
```

Negative check:
- Grep `agent.android` across cashier source (excl. build) → **no matches** (PASS).
- `src/agent/android/` directory does not exist; `src/agent/` contains only `cashier/` and `core/`.

Verdict: **PASS** — `agent.cashier` consistently used for Android package; `agent.core` unchanged as intended; no `agent.android` residue.

---

## 3. Kitchen Identity Residue — Full Search

Scope: all `*.java, *.gradle, *.xml, *.md, *.properties` under `android-print-agent-cashier`, excluding `build/` and `.gradle/`.

Classification definitions:
- **A. EXPECTED / SAFE** — generic docs, test fixtures, or legitimate clone-provenance text.
- **B. SUSPICIOUS** — ambiguous usage that could indicate forgotten identity but not yet blocking.
- **C. BLOCKING** — concrete identity collision (wrong prefs, wrong Keystore alias, wrong app ID, hard-coded Kitchen hardware/destination).

| Search string | Result in cashier source | Classification |
|---|---|---|
| `pos_agent_device_token` | No matches | — |
| `pos_agent_secure` | No matches | — |
| `"pos_agent"` (quoted) | No matches | — |
| `pos_print_agent[^_]` (checks for bare `pos_print_agent` not followed by `_cashier`) | No matches | — |
| `PRINTER_KITCHEN` | No matches | — |
| `86:67:7A:11:1C:A7` | No matches | — |
| `RPP02N` | No matches | — |
| `agent.android` | No matches | — |
| `android-print-agent` without `-cashier` | No matches | — |
| `../android-print-agent`, `project(*android-print-agent`, `fileTree*android-print-agent` | No matches | — |

Generic word `KITCHEN` (case-sensitive):
- `README.md:1` → `# POS Sate Gajah — Android Print Agent — Kasir (MVP; cloned from Kitchen)` — **A. EXPECTED / SAFE** — provenance/history text, not code identity.
- `test/DeviceApiProtocolTest.java:10` → `"destination":"KITCHEN"` in JSON fixture
- `test/DeviceApiProtocolTest.java:15` → `same("KITCHEN", a.job.destination, ...)`
- `test/JsonTest.java:10` → `"destination":"KITCHEN"` in JSON fixture
- `test/PrintPipelineTest.java:61` → `"destination":"KITCHEN"` in fake claim body
- `test/PrintPipelineTest.java:199` → `"destination":"KITCHEN"` in fake claim body
- All `KITCHEN` occurrences are in test fixtures asserting the generic claim parser handles any server-supplied destination string correctly. **A. EXPECTED / SAFE** — not a runtime hard-code.

Word `RECEIPT`:
- No occurrences of `"RECEIPT"` or `RECEIPT` as a hard-coded destination in `src/agent/cashier/*.java` or `src/agent/core/*.java` (grep `RECEIPT` on `src/agent/cashier/*.java` + `src/agent/core/*.java` → no matches). Test fixtures do not contain `RECEIPT`; they use `KITCHEN` as a sample value only.
- **A. EXPECTED / SAFE** for test domain; **no blocking residue**.

Verdict: **PASS** — no Kitchen identity residue in source/config. The only `KITCHEN`/Kitchen references are test-data strings and the README provenance sentence, both explicitly classified above.

---

## 4. Cashier Expected Values — Positive Confirmation

All required Cashier identifiers were found where expected (source excl. `build/`):

| Expected string | Locations (representative) | Count |
|---|---|---|
| `id.sategajah.printagent.cashier` | `build.gradle:16` (also merged manifest evidence) | 1 source + build artifacts |
| `agent.cashier` | `build.gradle:12 (namespace)`, `src/agent/cashier/*.java:1 (6 files)`, `src/main/AndroidManifest.xml:3,19,27,31 (package + 3 components)`, `test-android/*.java:1` (2 files) | 10 source hits |
| `pos_cashier_device_token` | `src/agent/cashier/SecureTokenStore.java:24` (`KEY_ALIAS`) | 1 |
| `pos_cashier_secure` | `src/agent/cashier/SecureTokenStore.java:25` (`PREFS`) | 1 |
| `"pos_cashier"` (prefs name) | `src/agent/cashier/BootReceiver.java:18`, `MainActivity.java:57,340`, `PrintAgentService.java:253,258,263,272` | 7 |
| `agent.cashier.START` | `src/agent/cashier/PrintAgentService.java:25` (`ACTION_START`) | 1 |
| `agent.cashier.STOP` | `src/agent/cashier/PrintAgentService.java:26` (`ACTION_STOP`) | 1 |
| `pos_print_agent_cashier` | `src/agent/cashier/PrintAgentService.java:30` (`CHANNEL`) | 1 |

All positions match the intended isolation design established in Phase 1A.

---

## 5. Token Storage Isolation

### 5.1 SecureTokenStore implementation

File: `android-print-agent-cashier/src/agent/cashier/SecureTokenStore.java` — read-only excerpt:

```java
private static final String KEY_ALIAS = "pos_cashier_device_token"; // line 24
private static final String PREFS = "pos_cashier_secure";           // line 25
private static final String PREF_CIPHER = "token_cipher";
private static final String PREF_IV = "token_iv";
...
private static SharedPreferences prefs(Context ctx) {
    return ctx.getSharedPreferences(PREFS, Context.MODE_PRIVATE);
}
```

- Keystore alias is exactly `pos_cashier_device_token` (required). No occurrence of `pos_agent_device_token` in cashier source.
- SharedPreferences name for ciphertext is `pos_cashier_secure`. No `pos_agent_secure` in cashier source.
- No fallback or migration path that reads Kitchen prefs.
- Cipher: `AES/GCM/NoPadding` via `AndroidKeyStore`, IV + ciphertext stored Base64 in prefs — same pattern as Kitchen but under distinct alias/prefs.

### 5.2 SharedPreferences isolation (UI config)

| File | Line | Code |
|---|---|---|
| `BootReceiver.java` | 18 | `getSharedPreferences("pos_cashier", MODE_PRIVATE)` |
| `MainActivity.java` | 57 | `getSharedPreferences("pos_cashier", MODE_PRIVATE)` |
| `MainActivity.java` | 340 | `"pos_cashier"` in `saveConfig()` printer MAC persistence |
| `PrintAgentService.java` | 253,258,263,272 | `getSharedPreferences("pos_cashier", MODE_PRIVATE)` (render options + `prefsString`) |

No file under `src/agent/cashier/` uses `"pos_agent"`.

### 5.3 Plaintext token audit

Scanned: all `*.java, *.gradle, *.xml, *.md, *.properties` under cashier source (excl. `build/`).

- Pattern `Bearer [A-Za-z0-9_\-]{8,}` (hard-coded Bearer literal): no matches.
- Pattern `token = "…"` / `device_token = "…"` style hard-code: no matches.
- All token references are:
  - `SecureTokenStore.save(Context, String token)` — parameter, never a literal.
  - `SecureTokenStore.load(Context)` — runtime decrypt.
  - `MainActivity.deviceToken` — EditText for operator to paste token once; saved via `SecureTokenStore.save()`, field cleared after save (`deviceToken.setText("")`).
  - `PrintAgentService.HttpTransport` — `private final String token` assigned from `SecureTokenStore.load(this)`, used only as `"Bearer " + token` header at request time.
  - `FileLog` — explicitly documented: `NEVER logs the token, authorization headers, or server bodies`; implementation sanitizes `error` and never includes `token`/`Authorization`/`body`.
- `README.md` describes token provisioning via UI (`tempel device token`) and Keystore storage — no embedded token.
- `local.properties` contains only `sdk.dir`.
- `build.gradle`/`settings.gradle`/`AndroidManifest.xml` contain no token.

Verdict: **PASS** — token storage fully isolated; no plaintext production token embedded. No `SECRET-LIKE VALUE FOUND` to report. The sole runtime `Bearer` construction is `"Bearer " + token` in `PrintAgentService.java:375`, which is expected transport code (not a hard-coded secret).

---

## 6. Android Component Isolation

| Component | File | Evidence | Verdict |
|---|---|---|---|
| Application | `src/main/AndroidManifest.xml:13-14` | `package="agent.cashier"`, `label="POS Print Agent — Kasir"` | PASS |
| Activity | `manifest:19` / `MainActivity.java:1,57` | `agent.cashier.MainActivity`, `package agent.cashier`, prefs `pos_cashier` | PASS |
| Service | `manifest:27` / `PrintAgentService.java:1,25-30` | `agent.cashier.PrintAgentService`, `package agent.cashier`, `ACTION_START/STOP = agent.cashier.*`, `CHANNEL = pos_print_agent_cashier`, prefs `pos_cashier` | PASS |
| Receiver | `manifest:31` / `BootReceiver.java:1,18-21` | `agent.cashier.BootReceiver`, `package agent.cashier`, reads `pos_cashier`, checks `SecureTokenStore.load()`, starts `PrintAgentService.ACTION_START` | PASS |
| FileLog | `FileLog.java:1` | `package agent.cashier`, `implements agent.core.PrintPipeline.Log`, token-safe | PASS |
| SecureTokenStore | `SecureTokenStore.java:1,24-25` | `package agent.cashier`, isolated alias/prefs | PASS |

No component references `agent.android.*` or `pos_agent*`. No explicit reference to the Kitchen application exists. The manifest uses fully-qualified names (`agent.cashier.MainActivity` etc.), not relative names that could resolve ambiguously.

Channel/action mapping:
- Kitchen (reference): `agent.android.START/STOP`, `pos_print_agent`
- Cashier (this audit): `agent.cashier.START/STOP`, `pos_print_agent_cashier` — distinct, no collision if both installed on same device.

---

## 7. Channel / Action Isolation

| Identifier | Cashier source location | Kitchen counterpart | Result |
|---|---|---|---|
| `agent.cashier.START` | `PrintAgentService.java:25` (`ACTION_START`) | `agent.android.START` | Cashier uses its own — PASS |
| `agent.cashier.STOP` | `PrintAgentService.java:26` (`ACTION_STOP`) | `agent.android.STOP` | Cashier uses its own — PASS |
| `pos_print_agent_cashier` | `PrintAgentService.java:30` (`CHANNEL`) | `pos_print_agent` | Cashier uses its own — PASS |
| `agent.android.START/STOP` | No matches in cashier source | — | PASS — none remains |
| `pos_print_agent` without `_cashier` | No matches in cashier source (pattern `pos_print_agent[^_]`) | — | PASS |

Intent usage:
- `MainActivity.java` starts/stops via `new Intent(this, PrintAgentService.class)` + `setAction(PrintAgentService.ACTION_START/STOP)` — class-bound, not stringly-typed cross-app.
- `BootReceiver.java:22` → `new Intent(context, PrintAgentService.class); start.setAction(PrintAgentService.ACTION_START);` — correct.

---

## 8. Bluetooth Isolation

File: `src/agent/cashier/BluetoothPrinter.java` (read-only)

- SPP UUID: `00001101-0000-1000-8000-00805F9B34FB` — standard Classic SPP, correct.
- Strategy preserved: secure RFCOMM → insecure fallback → `CONNECTION_SETTLE_MS 300` → `WRITE_SETTLE_MS 500` → `MAX_WRITE_ATTEMPTS 2` → `STALE_CONNECTION_MAX_IDLE_MS 60_000` — identical to Kitchen proven behavior.
- No hard-coded Kitchen printer MAC/name found:
  - Grep `86:67:7A:11:1C:A7` → no matches
  - Grep `RPP02N` → no matches
  - Grep `PRINTER_KITCHEN` → no matches
  - Grep `RECEIPT` in `src/agent/cashier/` → no matches
  - Printer identity is runtime-only: `MainActivity` discovers paired devices via `BluetoothPrinter.pairedDevices()` and persists selected MAC to `SharedPreferences("pos_cashier", EXTRA_PRINTER_MAC)`; `PrintAgentService.ensureConnected()` resolves that MAC against `pairedDevices()` at print time.
- No hard-coded Cashier physical printer identity either — MAC is configuration (`EXTRA_PRINTER_MAC`), not compiled-in.
- No `destination` hard-code; ESC/POS payload is generic bytes from `EscPosRenderer`.

Verdict: **PASS** — Bluetooth remains generic and configuration-driven; no physical printer identity embedded.

---

## 9. Server / Destination Isolation

Scope: `src/agent/cashier/*.java` + `src/agent/core/*.java` (relevant paths)

| API path | Kind | File & line | Value |
|---|---|---|---|
| Claim | Transport | `PrintAgentService.java:346` | `"/api/v1/device/print-jobs/claim"` |
| Result/ACK | Transport | `PrintAgentService.java:355` | `"/api/v1/device/print-jobs/" + jobId + "/result"` |
| Heartbeat (test path) | UI | `MainActivity.java:439` | `"/api/v1/device/heartbeat"` |

- Claim destination: **not hard-coded** in Android client. `DeviceApiProtocol.Claim.destination` is parsed from server JSON response (`o.str("destination")` at `DeviceApiProtocol.java:93`). `PrintPipeline` passes `job.destination` through `EscPosRenderer` input only; never branches on `KITCHEN` vs `RECEIPT`.
- Grep `"RECEIPT"` and `"KITCHEN"` in `src/agent/cashier/*.java` → no matches. (The word `KITCHEN` in `test/*` fixtures is not client code.)
- Grep `destination = "KITCHEN"` / `destination = "RECEIPT"` → no matches.
- Architecture verified: `device token → Server device identity (PRINTER_KASIR vs PRINTER_KITCHEN mapping on server) → server-derived destination in claim → print → ACK/result with `claim_token`. The Android client is destination-agnostic, as required. No server/PHP logic was introduced in cashier source.

Verdict: **PASS** — no destination hard-code; server remains authoritative.

---

## 10. Build Configuration (Static Check — No Execution)

| File | Field | Value | Expected | Verdict |
|---|---|---|---|---|
| `build.gradle` | AGP plugin | `com.android.application` version `7.4.2` | 7.4.2 | PASS |
| `build.gradle` | `namespace` | `agent.cashier` | `agent.cashier` | PASS |
| `build.gradle` | `applicationId` | `id.sategajah.printagent.cashier` | `id.sategajah.printagent.cashier` | PASS |
| `build.gradle` | `compileSdk` | `33` | 33 | PASS |
| `build.gradle` | `minSdk` | `29` (Android 10+) | 29 | PASS |
| `build.gradle` | `targetSdk` | `33` | 33 | PASS |
| `build.gradle` | `versionCode/versionName` | `1 / 0.1.0-mvp` | — | — |
| `build.gradle` | `compileOptions` | `Java 11` (source + target `VERSION_11`) | Java 11 | PASS |
| `build.gradle` | `dependencies` | `// intentionally empty — framework only` | zero deps | PASS |
| `settings.gradle` | `rootProject.name` | `pos-print-agent-cashier` | cashier name | PASS |
| `settings.gradle` | repos | `google(), mavenCentral(), gradlePluginPortal()` | — | — |
| `AndroidManifest.xml` | `package` | `agent.cashier` | `agent.cashier` | PASS |
| `AndroidManifest.xml` | permissions | `BLUETOOTH(30), BLUETOOTH_ADMIN(30), BLUETOOTH_CONNECT, INTERNET, FOREGROUND_SERVICE, FOREGROUND_SERVICE_CONNECTED_DEVICE, RECEIVE_BOOT_COMPLETED` | — | PASS |
| `AndroidManifest.xml` | components | 1 activity + 1 service (`connectedDevice`) + 1 receiver | — | — |
| `local.properties` | `sdk.dir` | `C\:\Android\sdk` | — | — |

Toolchain compatibility: Kitchen was validated against `Gradle 7.6.4 + AGP 7.4.2 + JDK 11 + SDK 33`; cashier `build.gradle` is byte-for-byte the same except the two identity lines (`namespace`, `applicationId`). Kitchen re-verification note from Phase 1A: `android-print-agent` still builds `BUILD SUCCESSFUL` — toolchain proven.

No cross-project `project()` dependency, no `fileTree` to Kitchen, no relative path.

Verdict: **PASS** — build configuration compatible with the proven toolchain; zero external dependencies preserved.

---

## 11. Project Independence

| Check | Method | Result |
|---|---|---|
| `android-print-agent` (without `-cashier`) in source | `Select-String` on all `*.java,*.gradle,*.xml,*.md,*.properties` excl. build | No matches |
| `../android-print-agent` relative path | same scope | No matches |
| Absolute path `C:\…\android-print-agent` (non-cashier) | same scope | No matches |
| `project(*android-print-agent` Gradle reference | same scope | No matches |
| `fileTree*android-print-agent` | same scope | No matches |
| Symlinks | `Get-ChildItem` attributes (no `ReparsePoint`) | None |
| Runtime dependency on Kitchen | No `dependencies { project(...) }`, no `include` to parent | None — copied tree is self-contained |

File tree under cashier (source/config only, excl. `build/`/`.gradle/`):
```

```

Verdict: **PASS** — cashier is an independent copied tree with no build/runtime dependency on Kitchen.

---

## 12. Source / Test Package Consistency

- `src/agent/cashier/` — Android package implementation — PASS (6 files, `package agent.cashier`)
- `src/agent/core/` — generic protocol/renderer/policy — PASS (6 files, `package agent.core`)
- `test/` — `package agent.test`, imports `agent.core.*` — PASS
- `test-android/` — `package agent.cashier`, `import agent.cashier.BluetoothPrinter` and `import static agent.test.RunTests.*` — PASS; consistent with BMP decision-layer test isolation pattern
- No test file still imports `agent.android.*` (grep `agent.android` → no matches)

Tests were not executed in this phase per scope (§13: do not modify or execute tests).

---

## 13. Kitchen Identity Residue Findings — Summary Table

| Finding | File:Line | Context | Classification | Why it matters |
|---|---|---|---|---|
| `KITCHEN` in test JSON | `test/DeviceApiProtocolTest.java:10` | `"destination":"KITCHEN"` fixture | **A. EXPECTED / SAFE** | Server destination is opaque to client; tests use KITCHEN as one valid sample. Not a client hard-code. |
| `KITCHEN` assertion | `test/DeviceApiProtocolTest.java:15` | `same("KITCHEN", a.job.destination, ...)` | **A. EXPECTED / SAFE** | Same as above. |
| `KITCHEN` in JSON parse test | `test/JsonTest.java:10` | `"destination":"KITCHEN"` fixture | **A. EXPECTED / SAFE** | Same pattern. |
| `KITCHEN` in pipeline fake | `test/PrintPipelineTest.java:61` | Fake claim body `destination:KITCHEN` | **A. EXPECTED / SAFE** | Same — exercises generic pipeline. |
| `KITCHEN` in pipeline stale test | `test/PrintPipelineTest.java:199` | Fake claim body `destination:KITCHEN` | **A. EXPECTED / SAFE** | Same. |
| `cloned from Kitchen` | `README.md:1` | Title suffix `(MVP; cloned from Kitchen)` | **A. EXPECTED / SAFE** | Provenance documentation; not a code identity. |
| Colon split in PowerShell table | — | Grep hit list shows `src/agent/cashier/PrintAgentService.java:25` repeated due to `:` in path | Not a source finding | Artifact of output formatting, not a file. |

**Suspicious findings:** none.
**Blocking findings:** none.

Hard-coded values of interest that were explicitly *absent* (confirming negative checks):
- Kitchen Keystore/prefs/action/channel strings — absent.
- Kitchen/Receipt destination strings in client code — absent.
- Kitchen printer MAC `86:67:7A:11:1C:A7` / name `RPP02N` — absent.
- Cross-project Gradle references — absent.

---

## 14. Generated Files

- `android-print-agent-cashier/build/` — debug APK, merged manifest, `BuildConfig.java` — ignored for isolation conclusions; contents correctly reflect cashier app ID (`id.sategajah.printagent.cashier`) as derived from `build.gradle`/`AndroidManifest.xml`.
- `android-print-agent-cashier/.gradle/` — ignored.

No generated file constitutes a primary identity claim; primary evidence is the source/config listed above.

---

## 15. Kitchen Reference Safety

- No write operation was performed under `C:\Users\M S I\Documents\PROJECT\POS SATE\android-print-agent` (verified by spot-reading `build.gradle`, `AndroidManifest.xml`, `SecureTokenStore.java` under that path; each still shows `agent.android` / `id.sategajah.printagent` / `pos_agent_device_token` unchanged).
- No Gradle task was run against the Kitchen project during this phase.
- No test suite was executed against either project during this phase.

---

## 16. Acceptance Criteria (16 Items)

| # | Criterion | Evidence ref | Verdict |
|---|---|---|---|
| 1 | Cashier application ID correct | `build.gradle:16`, merged manifest | **PASS** |
| 2 | Cashier namespace/package identity correct | `build.gradle:12`, `manifest:3`, `src/agent/cashier/*.java:1` | **PASS** |
| 3 | No accidental Kitchen Android package identity remains | `grep agent.android` → no matches | **PASS** |
| 4 | SharedPreferences isolated | `pos_cashier` in 4 files; no `pos_agent` in src | **PASS** |
| 5 | Keystore alias correct | `SecureTokenStore.java:24` = `pos_cashier_device_token` | **PASS** |
| 6 | No plaintext production token | Scanned all source/config; only `Bearer + token` runtime header | **PASS** |
| 7 | Actions/channels isolated | `agent.cashier.START/STOP`, `pos_print_agent_cashier`; no `agent.android.*` or bare `pos_print_agent` | **PASS** |
| 8 | No Kitchen printer MAC/name embedded | Grep MAC/name → no matches | **PASS** |
| 9 | No Cashier physical printer MAC/name incorrectly hard-coded | MAC from `pos_cashier` prefs only; no compiled-in MAC | **PASS** |
| 10 | Claim not hard-coded to `KITCHEN` | `src/agent/cashier/*.java` — no `"KITCHEN"` | **PASS** |
| 11 | Claim not hard-coded to `RECEIPT` | `src/agent/cashier/*.java` — no `"RECEIPT"` | **PASS** |
| 12 | Server remains authoritative for destination | `destination` parsed from claim response (`DeviceApiProtocol.java:93`), never branched | **PASS** |
| 13 | No runtime/build dependency on Kitchen | Grep Gradles for cross-project refs → none; file tree self-contained | **PASS** |
| 14 | Build config compatible with proven toolchain | AGP 7.4.2 / compileSdk 33 / Java 11 / zero deps | **PASS** |
| 15 | No server/PHP/database files were changed | Audit touched only cashier source + 3 Kitchen files for compare | **PASS** |
| 16 | No files were modified during Phase 1B | Only this report was created; `git status --porcelain` for kitchen/cashier still shows both as untracked independent trees | **PASS** |

## 17. Explicit Non-Action Statements

- **No implementation changes were made during Phase 1B.** This audit performed zero writes to source, build configuration, manifest, tests, or documentation under `android-print-agent-cashier` or `android-print-agent`. The sole file created is this audit report.
- **No production systems were contacted.** No heartbeat, claim, or result HTTP request was issued. No device token was provisioned. No print job was created. No physical printer was connected. No server log should show activity from this phase; the tablet hardware was not involved.

## 18. Final Verdict

**PHASE 1B STATUS: PASS**

- Identity, storage, channel, Bluetooth, destination, and independence properties are isolated and internally consistent.
- Remaining `KITCHEN`/Kitchen strings are limited to test fixtures and the README provenance note and are classified A. EXPECTED / SAFE.
- Zero blocking or suspicious findings.

Existing Phase 1A report not modified: `reports/PHASE_X4_11_I2_PHASE1A_CASHIER_AGENT.md` unchanged.

Hard stop — no APK install, no token provisioning, no Bluetooth pairing, no printing, no Phase 1C.
