சுருங்கல் செயல்பாடுNarrowing Function N(t)
Count of viable non-secessionist constitutional pathways attempted and not yet closed at time t.
N(t) = | { viable constitutional pathways attempted and not yet closed at time t } |§1What it measures
NF is the culmination model. It does not measure feeling; it counts pathways. A pathway is on the list only if it (a) was formally attempted, (b) was non-secessionist in form, and (c) is still open in the sense defined below.
The Narrowing Timeline (§ 02 on /case/narrowing) is the source list. N(t) is the operationalisation of that timeline into a single integer at each point in time.
§2Inputs & sources
(a) Negotiated pact: Bandaranaike-Chelvanayakam (1957), Dudley-Chelvanayakam (1965). (b) Devolution package: 13th Amendment (1987), Chandrika Constitutional Reform Package (1995), Draft Constitution (2000). (c) Internationally-backed mechanism: Cease-Fire Agreement (2002), UNHRC Resolution 30/1 (2015). (d) Domestic accountability mechanism: LLRC (2011), OMP (2017), Office for Reparations (2018).
- ◇/case/narrowing — 22-step timeline (source list for all pathway entries)
- ◇Tier-A primary sources cited within each step
A pathway is closed at time t if any of: (i) formally abrogated by its sponsoring government; (ii) formally withdrawn (e.g. 2020 co-sponsorship withdrawal from 30/1); (iii) substantively unimplemented for more than ten years with no published implementation roadmap and no measurable timeline.
- ◇Same as pathway types — closure is documented within the cited record of each pathway.
§3Worked reading
N(2026) under this counting rule is 0. Every pathway in the list above is either formally abrogated, formally withdrawn, or substantively unimplemented past the ten-year rule with no published roadmap.
N(t) = 0 is a finding about the established constitutional repertoire, not a finding about every conceivable remedy. New pathways can be added to the list at any time — the model is open, not closed.
If any closed pathway is reopened with a published implementation roadmap and a measurable timeline, N(t) increments and the model is correspondingly revised. If two or more are reopened, the structural-narrowing branch of the case is materially weakened.
