+# Rendering intent expectations, revision 2
+
+The PDF and both ICC profiles are byte-identical to `../rendering-intents`.
+Only the eight `shading-pattern-inherit` expected-intent rows are corrected:
+an absent pattern ExtGState RI inherits the graphics state at the defining
+content stream's entry. These are page streams, with initial RelativeColorimetric.
+The later paint-time `ri` does not replace that initial value.
+
+The original manifest is retained as historical failed-oracle evidence. Revision 2
+records its hash and the correction tool hash. No rendered pixel was used to
+select the corrected intent. Explicit pattern RI overrides are unchanged.
+
+Reference: Adobe PDF Reference 1.4, section 4.6.3, Table 4.23, printed page 231.
+
+Regenerate into a new directory:
+
+```sh
+python3 tests/cmyk_lut/correct_intent_oracle.py --output NEW_DIRECTORY
+```
+
+Validate with `tests/cmyk_lut/intents.py --corpus
+tests/fixtures/pdf/rendering-intents-context`. The separate four-page
+`intent-transparency` fixture covers initial page/Form state, repeated pattern
+use, explicit overrides, uncolored fill/stroke and luminosity masks.
