v1 hand-wrote set_aux_hidden_state_layers/get_eagle3_default_aux_hidden_state_layers
and the boot reproduced the identical 'Model does not support EAGLE3 interface'.
Reason: supports_eagle3() is an isinstance check against a runtime-checkable
Protocol whose members include a required ClassVar flag
(interfaces.py:1663 supports_eagle3: ClassVar[Literal[True]] = True), so methods
alone do not satisfy it. Inheriting SupportsEagle3 -- the idiom every model in
this image uses, including the fork's own DFlashLagunaForCausalLM -- supplies the
flag, SupportsEagleBase's has_own_lm_head/has_own_embed_tokens, and working
default implementations of both methods; the hand-written methods are deleted.
base 008eeaa2... -> patched 5eea89c5..., apply-verified against the pinned image.
Runbook: corrected method name, recorded the Protocol trap as the generalizable
lesson for future spec-decode ports.
glm53-dflash-01-aux-hidden-states.patch: implements the interface whose absence makes
the engine refuse the drafter with 'Model does not support EAGLE3 interface'. Adds
EagleModelMixin to Glm5NextModel, captures the single-stream hidden state entering each
requested layer in the loop, returns (hidden_states, aux_hidden_states) as a tuple when
the list is non-empty, and exposes set_aux_hidden_state_layers /
get_eagle3_default_aux_hidden_state_layers on Glm5NextForCausalLM -- the contract read
out of interfaces.py:1694/1712, eagle3_utils.py:26-31, deepseek_v2.py:1551-1585 and
cudagraph_utils.py:621, with kimi_k25/pixtral as the delegation reference.
Independent of the compile changelist (01-05); it patches the same file as 01, so 01
goes first if both are applied. Scope is honest in the header: this makes the interface
present (the prerequisite for driving DFlash2), it does not promise draft quality and is
not a decode-speed fix.
