First-pass narrow read — primary edge in Cost Advantage. Provisional, single-pass evidence.

Provisional score · subject to modification based on new evidence

Larsen & Toubro Ltd. scores 5.21 on MoatSCORE 6.0 — a narrow moat in Construction. This is a first-pass note: the dimensional read and the filing receipts below come from a single GFIP evidence pass, not the full two-pass deep corpus behind our flagship deep dives. Provisional — published free while the deep version is queued.

D8Ungoverned RiskUnscored · Layer 2.5

D8 rating: ADEQUATE. Not part of the moat score — it governs the cost of equity and the fade window. First-pass; not yet deep-reviewed.

The barrier gate

The barrier gate — first-pass

Replication — can a rival copy it?6.0
How hard it is for a rival to copy the edge (first-pass estimate).
Bypass — can a rival route around it?5.0
How easily a rival can route around the edge (first-pass estimate).

Effective barrier 5 — below 6, so the band is capped narrow. First-pass estimate.

What would change our mind
  1. Deep two-pass review. This draft rests on a single GFIP evidence pass; the full 10-year AR + concall corpus may move the read.

  2. The barrier gate. A firmer replication or bypass estimate is the most likely thing to shift the band.

  3. Adverse events. Any governance, regulatory or funding shock captured in D8 could re-rate the fade window.
