Defence indigenisation statistics commonly report item counts, production value and local manufacture. The programme's remaining dependence requires separate examination of engines, critical materials, depot repair and authority to modify the technical baseline. Those are different vulnerabilities. The following evidence map places the published India Front cases in separate control categories so that no one indicator is mistaken for the whole defence-industrial position.
Evidence selected from India Front reporting published August–October 2026. The dated observations are not a comprehensive October readiness audit.

| Control layer | Published observation and date | Demonstrated | Not demonstrated by this record |
|---|---|---|---|
| Foreign critical input | HAL's February 2026 update, analysed in The External Veto, 20 August 2026: nine Tejas Mk1A aircraft built and flown, with deliveries awaiting imported F404 engines | Airframe progress can coexist with an external engine-delivery dependency | That the complete fleet was unavailable for every mission, or that every imported part is a strategic veto |
| Domestic supply concentration | Army indigenisation of 159 of 175 ammunition variants, with 110 variants reliant on one domestic replenishment supplier, as reported in The External Veto | Replacing imports can still leave a single domestic point of interruption | The military's actual war-stock endurance or the likelihood that any supplier will fail |
| Material qualification | MIDHANI/DRDO qualification milestones dated October 2025, January 2026 and April 2026, documented in Issue 6's Indigenisation Closes at Qualified Use | Identified alloy grades, forms and parts advanced through specific aero-engine production/clearance steps | Blanket interchangeability of all Indian alloys or qualification for unrelated applications |
| Overhaul and sustainment | HAL's Su-30MKI support history, 2017 agreements, 2024 engine-production contract, in Indigenisation Must Reach the Support Chain, 8 October 2026 | Indian production capability grew while support, technical assistance and repair capacity followed a separate trajectory | Complete autonomy of every repair procedure, replacement part or future upgrade |
| Engineering-change authority | Transfer procedures and the Pinaka documentation history reviewed in The Drawing Is Not the Factory, Issue 6 | Producing to a baseline can precede finalisation of technical authority and control of later changes | That possession of drawings alone gives a firm authority to certify a redesigned component |
How to read the layers
Source continuity asks whether the programme can obtain a critical input when needed. An imported item can be commercially secure through diversified supply and stocks; domestic production can be fragile when only one qualified line exists. Country of manufacture does not settle concentration risk.
Qualification authority asks whether the material, part or process has been accepted for its specified safety- and mission-critical application. MIDHANI's reported approvals are meaningful precisely because they name grades, forms, production routes and uses. They cannot be generalised into a statement that every related part is indigenised.
Lifecycle authority asks who can maintain, repair and modify the deployed system over decades. A contract to manufacture engines or aircraft is not automatically a contract conveying the design data and certification rights needed for successor changes. The entity able to approve a change may differ from the factory able to make it.

| Capability examined | Named platform, component and operational use |
| Exposure type | Import interruption, domestic concentration, unqualified process, overseas sustainment, restricted technical authority |
| Confirmed evidence | Document, reporting date, period observed and precise claim |
| Competent owner | Service, programme office, manufacturer, technical authority or supplier as applicable |
| Consequence under denial | Not established unless a credible readiness or sustainment assessment exists |
| Evidence needed next | Delivery schedule, qualified alternative, stock endurance, repair right or change-approval record |
This is an evidence-classification instrument, not a substitute for the classified Sovereignty Annex proposed in The External Veto. No speculative 30-, 90- or 180-day readiness score is assigned. Classified stocks, actual operational serviceability, denied-access probabilities and licence terms cannot be inferred from the public record.
Intelligence finding
The cases establish several forms of industrial progress and several different unresolved exposures. Imported propulsion, domestic single-source ammunition, qualified alloys and sustainment rights belong in separate lines of a defence capability account. A single localisation percentage conceals the actual exposure and misassigns accountability.
