Review follow-up: the per-step gate recomputed view(previous) on every
changed apply — a property read for identity-stable views, but a fresh
throwaway object per change for computing views. The registry now keeps a
WeakMap from state object to raw view: the previous state's view was
cached when that state was current, so each distinct state's view computes
exactly once (gate and snapshot share the memo) and the quiet path
allocates nothing. Unlike the earlier lastView record, an entry is keyed
by the state itself — the view of that exact state by the pure-view
contract — so no stamping discipline exists to get wrong. Primitive
states bypass the WeakMap and compute directly.
Review consensus: for the only declaring unit the token function was
literally the view function, so the extra wire member bought nothing —
default raw-view comparison produces the identical Object.is on
state.turns at the identical cost (one property read per side). The
per-step gate stays: it holds the no-stored-baseline property, and its
measured overhead (~ns per changed state) is four orders of magnitude
below the push path it guards.
Review follow-up (imccyu): comparing view(previous) recomputes the view on
every quiet change. The wire block now takes an optional viewKey(state)
declaring the cheap comparison token; the drive compares tokens across the
previous and next states and calls view only for an actual push. Default
stays the raw view output. turnOutline declares viewKey: state => state.turns,
making the identity-stable-turns convention an explicit contract; the
registration erasure forwards viewKey (dropping it silently reverted the
gate to the fallback, caught by the new view-call-counting test).
Review suggestion (imccyu): the drive holds both the previous and next
state, so the identity gate can compute view(previous) and view(next) in
the driving step and compare them directly. The stored lastView cell field
and its stamp-on-every-change rule are deleted; with no dedup memory,
nothing can go stale across listener generations by construction, and a
rebuilt cell no longer pushes an unchanged view on its first live event.
Costs one extra pure view() call per changed state.
The change feed stamped lastView only when a listener was subscribed, so a
value change during a listener-free window (HMR swap) froze the baseline
and a later transition back to the old value was silently deduplicated.
The baseline now advances on every changed state, heard or not; broadcast
still only happens with listeners. Docs, catalog, and the feature note
follow the corrected semantics.
The feed previously fired on every changed state reference of a
client-visible unit; it now also compares the raw view output against
the last delivered one and stays quiet when Object.is-identical, so a
unit can buffer working fields in state behind an identity-stable
projection. Units whose views build fresh objects per call are
unaffected.
The review's carry-over: 'each has a published backend' in the CodeRuntime
JSDoc and its projections (tool-cordis api-catalog, subsystems page) plus
'both shipped'/'backends ship' in the code-runtime README all claimed the
Python backend is released; it is private and experimental, excluded from the
release family. The wording now states the TypeScript backend is released and
the Python backend is experimental and private (not published), in the JSDoc
(api-catalog regenerated to match), the READMEs (paired), and the subsystems
page (paired).
Adding a published Python backend and reordering `flush_line` left several
owning documents stating things that are no longer true.
`src/invariant.ts` justified its empty installer with "ships only the fd-3
wire-protocol codec", which the subprocess execution path contradicts. The
reason now states the actual one: every relation this backend maintains lives
in the CPython child or on the fd-3 wire, so no same-process event sequence is
observable from a listener -- the same shape the sibling worker-thread backend
uses.
The seam's `PORTABLE_RESERVED_WORDS` and `language` JSDoc, the code-runtime
README pair, and docs/subsystems/code-runtime both said only TypeScript has a
published backend. Corrected in all four, with the generated cordis catalog
regenerated for the `language` change.
The note attributed the 12x multiple to the settlement flush holding three
copies. That stopped being true when `flush_line` was reordered to drop the
pending chunks before its push: the binding worst case is the newline path's
single near-budget write. Corrected in the note (both sides) and in the test
comment that repeated it.
The note's Testing section now registers the cases this stack added, and the
Chinese side receives the O(depth) entry it never got plus the new ones -- it
had drifted from the English.
`INTERPRETER_BASELINE_BYTES` argued 64 MiB from a RESIDENT set while RLIMIT_AS
bounds address space. It now cites the bootstrap's own measurement (30.23 MiB
of mappings for `python3 -I`), making 64 MiB roughly twice the measured
baseline.
Also: a hardcoded `(:232-235)` comment reference becomes a reference by name,
a "which now walks in O(depth) too" change narrative becomes a current-state
statement, and a stray double blank line is removed.
Review round on #3316: the composition inventory answers from a standing
mount before the broken verdict (a file corrupted after mounting no longer
hides the running composition), livePresetMounts filters by the caller's
root fiber so a second Cordis runtime in one process never answers for it,
compositions carry trust and the plugin list resolves shipped preset names
through the shared dsh-agent-presets/display fold over ui-agent-preset's
dictionaries (INLINE_SAFE inline import; no cross-plugin runtime import),
the condition detail label reads Disabled when/禁用条件, and the stale
four-surfaces comment says three.
Reconciled with the scope-grouped plugin list: compositionInventory keeps
its additive block over master's RemoteError refactor; the slimmed
settings-store keeps ctx-based signatures while staying a display-only
roster store (no describeFace, no select); dead transport-rejection tests
dropped with the wire that no longer rejects; module graph, catalogs, and
harnesses regenerated against the merged tree.
The settings plugin list projected ctx.loader.entries() alone, hiding the
plugins sessions actually run and rendering the web overlay's deliberate
disabled tombstones (tool-bash, tool-fs, ...) as two dozen plainly disabled
rows while the same modules ran in every standard-preset session.
- dsh-agent-presets: compositionInventory() answers flattened rows per
preset — newest live standing generation when mounted, composition file
otherwise with !!js disabled gates evaluated against the Loader context;
reading never mounts (regression-tested), refusal stays 'conditional',
raced files report broken with the reason.
- dsh-host-plugin-inventory: list() gains an optional agentPresets block,
resolving the roster as an optional peer and mapping fiber states to the
public phase vocabulary.
- ui-settings-plugin-inventory: preset group first behind a display-only
switcher opening on the default preset; global group collapsed with
failures floated; host-disabled modules enabled by >=1 preset fold into a
session-plugins drawer naming providers; search spans scopes and points
at matches in unselected presets.
- ui-agent-preset: the General-settings default-preset row is deleted — the
roster section's make-default and the new-session chip keep the field —
and the settings store slims to the display roster the header label reads.
Docs, catalogs, module graph, settings-chrome goldens, and the bilingual
Agent Note ride along.
- gen-cordis-catalog / gen-cordis-inspect-catalog / gen-client-catalog /
gen-config-catalog / gen-doc-graphs / gen-module-graph outputs pick up
the converged Remote vocabulary (gateway/* codes, RemoteError JSDoc)
and the dsh-util-time package; the zh sides of the three
English-generated pages follow the same line-number shifts.
- the message-feedback protocol golden records the accepted wire
change: a boundary-validation failure now reports
gateway/input-invalid with structured details instead of a bare
internal code.
- new cookbook page adding-a-remote-api (en/zh): the five-step HOW-TO
for declaring, failing, registering, consuming, and testing a Remote
endpoint.
- new Agent Note ctx-remote-failure-vocabulary records this round's
decisions and alternatives; the 2026-08-02 and 2026-08-10 notes are
rewritten to the shipped facts (RemoteError vocabulary, $host, the
retired ApiProxy statements).
- package READMEs pick up the new failure-face contracts
(typert/protocol, api/gateway, api/remotes,
test-support/client-runtime), dsh-util-time gains its README and
registry entries, and stale connection/WorkspaceError/legacy-code
statements are corrected (ui-settings, ui-settings-models,
workspace-controller, docs/subsystems/typert incl. the
TypertGatewayErrorCode type-equiv block).
- packages/AGENTS.md gains the Remote-failure rule bullet; its doc
budget rises 675 -> 714: the bullet is the compressed remainder
after relocating detail to the cookbook and the Agent Note.
Master replaced the session-log-version-mechanism note with the
fail-closed-session-event-vocabulary note; update the rename note's links
(en/zh) so cross-links resolve.
Rename the tool-presentation transport from code-mode to ptc everywhere
that is not written into session logs: the mode config value becomes 'ptc',
the preset directory/id becomes ptc, the demo becomes demo:ptc, the
dispatch waterfall becomes tools/ptc-dispatch-log (types PtcDispatch*), the
prompt rule becomes tools:ptc-only, source/test files become ptc.ts etc.,
and prose says PTC mode / PTC 模式. The session-persistent vocabulary
(durable events tool/code-dispatch*, logged plugin name tools-code-mode,
sub-call id segment :code:) intentionally stays and moves in the stacked
persistence PR, which is blocked until the SESSION_FORMAT_VERSION v0→v1
migration lands with it. run_code, its code parameter, CodeSdkLanguage,
CodeRunFailedError, the dsh-code-runtime family, third-party codex names,
and frozen archived notes keep their names.
