Issues

• HermitCrab analysis: combined stack cut work 14-64% on four real grammars, but R2 is closed; re-measure without it (unmeasured)

• HermitCrab: a restricted clitic adds 17.5% work steps, mostly host search that repeats per MSA (measured on the port)

• HermitCrab: do literal-identity and natural-class restoration on hc.dll match the port's fixes? (unmeasured)

• HermitCrab: #546 follow-ons (compiled slot-rule sharing, ParallelApplySlots) are unbuilt and unmeasured in work steps

• HermitCrab synthesis: 98% of Mbugwe synthesis work goes to candidates whose root lookup hits but never match the surface

• HermitCrab: 86 of 1,645 Mbugwe words hit the 2M step cap and carry about two-thirds of its work; causes not examined

• HermitCrab analysis: dead-internal work is material only on Aweti (39.8%) and v1 (12.2%); shadow-mode summary not run (research lead)
