What is measured?
Indexed source tokens are the truth-bearing project material processed by the completed project index. Whole Project Context tokens are the compact project packet prepared for broad project reasoning.
TruthSpine product guide
Measured on real projects, with the boundaries stated
Review TruthSpine's measured real-project source and Whole Project Context token counts, methodology boundaries, and results.
TruthSpine measures the source tokens it indexes and the compact Whole Project Context it prepares for an agent. The published results exclude dependencies, generated output, binaries, secrets, and TruthSpine's own files. Context reduction is not a claim that an agent permanently remembers every source detail.
What is excluded?
Dependencies, generated artifacts, binary files, secrets, and TruthSpine's own files are excluded so the comparison reflects meaningful project source.
What does reduction mean?
It measures how much smaller the prepared context is than the indexed source corpus. It does not guarantee output quality, permanent model memory, or complete recall of every source detail.
Why publish the method?
Agents and people should be able to distinguish measured evidence from promotional language. TruthSpine publishes the inputs, outputs, exclusions, and interpretation together.
