ChatView's bottom-follow recognized only wheel gestures as reader input,
so touch panning, scrollbar dragging, and keyboard paging could not leave
the bottom of a streaming transcript. Replace the wheel listener with
device-agnostic attribution: a scroll position deviating from the
observed-top ledger of the last delivered or written scrollTop is reader
input. Adds keyboard-paging and touch-style fling e2e scenarios (red under
the old implementation) and the bilingual Agent Note triplet.
The inline comment called every dunder entry "the Python backend's" slot,
but `__debug__` is a CPython compile-time constant, not a seeded slot;
align the comment with the seam declaration, which is the single home for
why each entry is reserved.
- index.ts: RESERVED_ERROR_MEMBERS JSDoc now says `__x__` (non-empty
middle), matching DUNDER_MEMBER and the derivative docs; and
PORTABLE_RESERVED_WORDS is described as covering portable *target*
languages (Python is a later-PR backend, not yet shipped).
- types.ts + type-equiv docs: CodeBindingNamespace.global points to
RESERVED_BINDING_GLOBALS by name with an `e.g.` sample rather than
enumerating the set (single home), no longer implying `__debug__` is a
seeded slot.
- Agent Note: separate `__debug__` (CPython compile-time constant) from
the seeded bootstrap globals.
- README (en/zh): document the four exported exclusion sets and the
portable identifier/naming contract — no cross-package link needed.
- Regenerate cordis services catalog for the shifted source line.
- Agent Note: correct the stale worker-adoption paragraph — the worker
consumes the seam constants directly by name (no RESERVED_WORDS /
RESERVED_ERROR_PROPERTIES re-alias) — and describe DUNDER_MEMBER as
`__x__` (non-empty middle).
- types.ts: document RESERVED_BINDING_GLOBALS on CodeBindingNamespace.global
(names like `__dsh_main__` pass the identifier rule but are still refused)
and the non-empty-middle dunder rule on memberNameProperty; propagate to
the type-equiv derivative docs (both languages, re-recorded).
`____` has an empty middle between the two `__` pairs and does not match
`/^__.+__$/`; assert that (not a match) and add `__x__` as the shortest
real dunder form that does.
- Worker consumes PORTABLE_RESERVED_WORDS / RESERVED_ERROR_MEMBERS by
their seam names directly, dropping the local re-alias (symmetry with
the other two imported constants).
- Split the reserved-vs-duplicate diagnostics: a backend-owned global now
reports "reserved binding global", not the misleading "duplicate".
- DUNDER_MEMBER uses `__.+__` so a bare `__` (empty middle, not a real
CPython dunder) is not matched; add coverage.
- Worker misuse tests add `a$b` (second-char `$`) and `lambda` (Python
keyword) so the identifier narrowing and reserved-word adoption are
each pinned directly, not only transitively.
- Clarify the seam JSDoc (dunder-vs-explicit-set wording, Python backend
is a later stack PR) and record in the Agent Note the obligation to
widen RESERVED_BINDING_GLOBALS when the bootstrap seeds more globals.
Update the type-equiv blocks in docs/core-data-structures/code-runtime
(both languages, re-recorded) to mirror the new CodeBindingNamespace /
CodeBindingErrorClass JSDoc, and regenerate the cordis services catalog
for the shifted source line. Keeps the worker-only intro until the
Python backend package exists.
