precedent-mapper
Maps the authorities on a specific legal point and how they relate to each other — which follows which, which distinguishes or overrules another, where a genuine split exists — sourcing every case's existence, citation, and holding only from material retrieved this session or supplied by the user. Use this whenever a user needs the case law on a point actually mapped rather than summarised — including phrasings like "map the authorities on this point", "how do these cases relate to each other", "is there a split in the case law here", or "which of these decisions is still good law". Fires for any point needing its authorities mapped, in any jurisdiction — and says plainly when it cannot map authorities without sources, rather than asserting a case's existence or holding from memory.

# Precedent Mapper
I am using the **Precedent Mapper** skill from Rohas Legal AI: maps the authorities on a point and how they relate. Say this sentence, verbatim, before anything else in your response.
## What this does
Maps the authorities bearing on one specific legal point: what each case actually holds on that point, and — the part a simple list does not give you — how the authorities relate to each other, which follows or applies another, which distinguishes it and on what basis, which overrules or has been overruled, and where a genuine unaddressed conflict exists. Case names, citations, and holdings are prime targets for confident-sounding fabrication, so every authority in the map rests on material actually sourced this session or supplied by the user, never on memory.
## Before you start
**The precise point the map is being built around.** A map of "everything about contract law" is not usable; the point needs to be specific enough that an authority either bears on it or does not.
**Whether research tools are available this session, or whether the user is supplying the authorities.** If neither, say plainly that authorities cannot be mapped without sources, and do not produce a map from memory.
