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 `$`) and `lambda` (Python
keyword) so the identifier narrowing and reserved-word adoption are
each pinned directly, not only transitively.
- Clarify the seam JSDoc (dunder-vs-explicit-set wording, Python backend
is a later stack PR) and record in the Agent Note the obligation to
widen RESERVED_BINDING_GLOBALS when the bootstrap seeds more globals.
Update the type-equiv blocks in docs/core-data-structures/code-runtime
(both languages, re-recorded) to mirror the new CodeBindingNamespace /
CodeBindingErrorClass JSDoc, and regenerate the cordis services catalog
for the shifted source line. Keeps the worker-only intro until the
Python backend package exists.
Move the reserved-word, reserved-global, reserved-error-member, and
dunder exclusion sets from the worker backend up to the code-runtime
seam package, and narrow the portable identifier subset to drop the
JS-only `$`. Every backend now imports one contract so a binding
namespace list valid on one backend is valid on all.
Delivers only the seam extension and the worker's adoption; the Python
backend, py-types renderer, and Code Mode language dispatch are later
PRs in the stack that depend on these exports.
- subagents.history computes its projections best-effort on both arms
(a hostile unit's fold rejection serves the page without the block,
matching the session-list precedent) with dual-arm coverage
- the lifecycle-witness spec probes every field of the seven-key
witness, protecting the key list itself
- list-children's own module docs catch up with the seq-gate contract,
and the design note records the rung-two later-event window as an
accepted, self-healing deviation of the corruption class
- the cached-identity rung gains a finality gate: the identity value
carries its descriptor seq and a cached row is served only when that
seq lands in the child's own suffix, so a fork seed's replayed
ancestor identity can never outrank the authoritative refold
(stateVersion bumped for the state-shape change)
- the cold preparation validates the inspected header against the
enumerated candidate's lifecycle witness; a republished id degrades to
that child's corrupt diagnostic instead of leaking the new owner's log
- the new projection registration proves HMR disposal; companion notes
qualify the superseded decision text and record the deliberate
error-face asymmetry
subagents.history drops its session-query read: a live child serves its
in-memory events with the registry watermark snapshot, a cold child goes
through inspectServable with a detached fold, and the retired
SESSION_QUERY_* arms disappear while every wire face stays put. The
design note records the shared read source.
- the subagent projection's empty state becomes a serializable null
sentinel (undefined fields vanish in JSON push frames, leaving stale
identities in clients); consumers treat null and a missing key alike,
and cached sentinels defer to the authoritative refold
- the tool catalog generator mounts the projection registry for
list_agents; the shared unavailable-error copy goes catalog-neutral
- the design note's verification section records the new
subagent-diagnostic snapshot honestly, the 2026-07-22 note's test
inventory is rewritten to the current mechanism, and the session-store
error code is documented
Cold children consult the optional session-projection-cache checkpoint
before paying a preparation recompute: the identity is immutable once
appended, so a cached value is definitive regardless of its watermark.
The cache stays a read-only accelerator (absent service or any rung-two
fault falls through silently; verdicts stay with the authoritative
refold), and the note plus core-data-structures pages describe the
three-rung ladder.
- listChildren contains per-child projection faults on both ladder rungs
(any registered unit's fold/schema rejection maps to that child's corrupt
diagnostic) and pins the whole-enumeration listing-failure rethrow
- the base bundle mounts session-projection (web-app's own insert retired
to avoid the double mount); stale composition comment updated
- the shared projections-unavailable wire face is pinned across
list/history/prompt; retired session-query arms removed from the catalog
paths
- the design note records the unknown-parent semantics shift and the
fold-fault isolation rule
Mounting session-projection in the example compositions staled the
generated composition and module graphs; the 2026-07-22 note now
describes the retired optional-session-query spec without a live path.
