Phase 189feature flag and kill switch design onlyFAEDA-EVIDENCE-AUDIT-RUNTIME-BUILD-APPROVAL-GATE-DESIGN-001

Evidence Runtime Feature Flag + Kill Switch Design

Defines disabled-by-default flags, role scope, zone scope, emergency stop, rollback levels, and audit visibility before evidence runtime can be exposed.

Runtime approval Previous gate Next gate Control room

Runtime remains blocked

Can FAEDA stop every evidence runtime path faster than it can fail?

Runtime remains blocked. No live runtime is created here. This gate is allowed to clarify readiness, controls, blockers, and exit criteria. It is not allowed to create production runtime, mutate evidence, notify users, export data, delete records, or grant external access.

Approval focus

What this gate must prove

1

Every runtime candidate gets a separate feature flag and separate kill switch.

2

Founder/admin sees global status, but cannot bypass data protection or security blocks.

3

Flags must support off, local_stub, sandbox, pilot, and production-ready states.

4

Kill switch must stop uploads, views, exports, workers, notifications, and external access separately.

Readiness checks

Checklist before next phase

1

default state is off

Must be proven before this gate can move forward.

2

rollout scope is tenant/role/zone aware

Must be proven before this gate can move forward.

3

emergency stop has owner

Must be proven before this gate can move forward.

4

flag changes are audit logged

Must be proven before this gate can move forward.

5

fallback UX is defined

Must be proven before this gate can move forward.

6

re-enable requires checker approval

Must be proven before this gate can move forward.

Blocked runtime

Blocked runtime actions remain locked

production evidence upload
real object storage write
live metadata mutation
queue worker mutation
notification dispatch
report export/download
external auditor grant
deletion/archive/purge
payment or settlement action
legal hold release

Exit criteria

How this gate becomes ready

1

Runtime can be disabled without code deploy.

Must be proven before this gate can move forward.

2

Partial shutdown paths are defined.

Must be proven before this gate can move forward.

3

Flag state is visible in founder control.

Must be proven before this gate can move forward.

4

Next phase can design metadata schema safely.

Must be proven before this gate can move forward.

Audit fields

Future gate packet fields

phaseGateId

string

Stable id for the future approval or stub gate.

sourceGate

string

Previous gate or upstream evidence governance design.

mode

enum

design, local_stub, sandbox, test_matrix, qa_gate, pilot, release_control.

featureFlagKey

string|null

Disabled-by-default feature flag for future runtime.

killSwitchKey

string|null

Emergency stop control for future runtime.

makerRole

enum

Role preparing the gate packet.

checkerRole

enum

Independent reviewer role.

riskSummary

string

Founder-safe risk summary.

status

enum

draft, blocked, rework, approved_for_next_gate, rejected.

createdAt

datetime

Future packet creation timestamp.

updatedAt

datetime

Future packet update timestamp.

Hard rules

Safety sprint does not equal live runtime

1

This phase is design, readiness, stub, sandbox, QA, pilot, or release-control planning only.

2

Do not create production evidence databases, migrations, API routes, object storage writes, queue workers, schedulers, notifications, exports, downloads, deletion, archive, purge, public links, or external auditor access here.

3

Any stub must be disabled by default, demo-data only, feature-flagged, kill-switchable, audited, and unable to mutate live evidence.

4

Backend permission checks remain final. UI visibility is never security.

5

No provider credentials, signed URLs, raw file paths, CNIC, OTP, PIN, bank details, private notes, payment references, or raw transcripts may appear in the UI packet.

6

Every runtime move must preserve maker-checker separation, idempotency, audit events, rollback, redaction, retention, and founder visibility.

Next safe gate

Phase 190 should be evidence metadata database schema approval design

The next move stays within the controlled runtime safety sprint unless Phase 200 returns FAEDA to the main core app completion track.
