The chat stats line took its token totals from the loaded conversation nodes,
so paging changed them and compaction erased the billing behind replaced
content. It also had no way to show context occupancy: the numerator and
capacity never reached the browser.
Both now come from token-meter session projections read through the standard
useProjection seat. Window nodes keep supplying turn and step counts plus LLM
and tool wall times, which are correctly window-scoped facts about what is on
screen; accounting no longer comes from there.
`tokenUsage` supplies billing and cache hit. `contextPressure` supplies
occupancy, pairing the newest provider-reported prompt size with the newest
capacity recorded by `request/context`. Deployments without token-meter drop
the token groups; a route whose adapter advertises no capacity drops the
occupancy group rather than rendering a placeholder.
Occupancy is deliberately approximate: the numerator and capacity are
independent last-wins fields, not one atomic request observation, so switching
models pairs a fresh capacity with the prior route's pressure until the next
request reports usage. It is a user-facing reference figure that nothing in the
harness makes decisions from, and it matches how the TUI status line has always
computed occupancy. The Agent Note and token-meter README state this as a
decision, including why the atomic alternative was implemented and rejected, so
it is not re-litigated as a defect.
Snapshot delta is one added `Context N% of 128K` segment across eight web
goldens; the preceding commit absorbed master's pre-existing golden drift.
Documentation only; no behavior change.
`firstLiveSeq`'s JSDoc still stated the boundary sits at that seq
unconditionally. Verified reachable on a plain production path: pick up a log,
do no work, pick it up again — the seed already ends in a boundary, so it is
not re-marked and `events[firstLiveSeq]` is undefined. Both that claim and the
firehose-gap sentence are now conditional, with the locate rule ("scan for the
last boundary") matching what types.ts already said.
`repair.ts`'s header claimed this module supplies the boundary. It does not —
the constructor does; this module supplies the activity read that must skip it.
Reworded, and it now names the closer timestamp leak, which is the one real
coupling that justifies `lastActivityTime` living beside the repair synthesis.
Recorded that `Session`'s constructor is the boundary's only legitimate writer,
since the invariant companion constrains nothing and a plugin-side append would
silently turn live brackets below it into dead history.
The seam README states the JSON-shaped write boundary, watch-disposer
quiescence, async listener containment, and the drained teardown; the
provider README rewrites Behavior around the operation chain,
read-modify-write, writer lock, ready reconcile, and leaf-level YAML
diffs, and updates Known Limitations to the residual guarantees.
A new Agent Note records the round's decisions and supersedes the
original note's deferred-lockfile alternative (cross-linked in place).
Chinese counterparts updated pair-by-pair (three briefed minimal
updates, one whole-document translation); type-equiv, config, cordis,
and module-graph catalogs re-recorded.
- `SessionSummary.updatedAt`'s wire doc still said "Persisted file mtime",
which stopped being true for attached sessions.
- The core invariant let `session/inherited` fall through the merge-extensible
default. It is core-owned, so it gets an explicit case; an unbalanced seed
legally places it inside an open turn, which the relation permits.
- The Agent Note claimed the boundary reaches disk via `live.pending`/
`scheduleDrain`. Verified false: the constructor append precedes `enter()`,
so it never publishes on `session/event` and rides the creation seed instead.
Attaching is therefore a write where none happened before — recorded, since
only `load()` stays a pure read.
- The deferred-index proposal asserted this change documented the cold-mtime
skew on `dsh-host-apiproxy`. It did not; the README entry now exists.
- `firstLiveSeq`'s firehose gap runs through its own seq, not below it.
- The boundary is not always at `firstLiveSeq` (the idempotence guard), so
consumers scan for the last one.
- `lastActivityTime` excludes by type, so a pickup time still leaks onto a
synthetic closer when a boundary ends an open turn. Documented.
- Pin the fork claim end-to-end: a child inherits a still-running parent's
open bracket below its own boundary, while the parent has none. Fails if the
write moves back to the load path.
- Fix the telemetry title that contradicted its own assertions.
The `/status` call site cannot be pinned the way the other two are: the
command appends its own `command/run` before rendering, so the boundary is
never the log tail there. Its fixture now at least renders over a
boundary-bearing log.
Conflict resolution notes:
- StatsLine: master redesigned the row into pipe-separated groups with LLM and
tool wall times. Kept that design and swapped only the token accounting
source, so counts and durations stay window-scoped while billing and context
occupancy read the durable projections.
- Generated artifacts (cordis catalog, module graph, event producer/consumer,
i18n pairing hashes) and web snapshots took master's side; they are
regenerated and re-recorded after this merge.
- Web e2e goldens and details-panel/timeline assertions took master's side:
that evolution is unrelated to this branch.
- ui-conversation package.json: kept master's devDependency ordering, re-adding
only the token-meter entry this branch needs.
`isInheritedSeq` had no production caller — only its own tests — so it was
a public core export shaped by nothing. A bracket owner reads the boundary
positionally; the helper belongs with the compaction seam, where a real
consumer decides its signature.
Also condense the `session/inherited` and `lastActivityTime` docs.
A plugin owning a standalone open/close bracket cannot tell a dead marker
from a live one: an unmatched `compact/start` reads identically whether the
previous writer died mid-compaction or a compaction is running now.
`Session.firstLiveSeq` already holds that answer exactly, but only in memory.
Append the log-only `session/inherited` event at that seq from the seeded
constructor — the single waist all six seeded-start paths pass through
(resume, configured startup on a persisted id, `sessions.fork()`, a subagent
fork child, `adopt()`'s live prefix, and a bare seeded `create`). Read it
through the new `isInheritedSeq(events, seq)`.
The constructor placement means persistence needs no changes: the marker is
already in `events` when a backend captures the creation seed, so it rides
the ordinary seed path with no load-time write. It also covers fork, where
the inherited bracket's owner may still be running — the case a
persistence-layer boundary could not reach.
Activity ordering excludes the boundary through `lastActivityTime()`, since
lazy resume makes browsing a pickup and the three call sites would otherwise
float every opened session to the top of a picker or list.
Conflicts, all in files this branch and master both touched:
- `chat/helpers.ts` — kept both sides. Master replaced the inline env
filter in `gitBranch` with `scrubbedParentEnv()`; this branch added the
surface-marker and compaction-source imports.
- `docs/module-graph.md` — regenerated. Both sides added a `tui` edge
(master `subprocess`, this branch `compact`); the generated row now
carries both.
- Three `.i18n.yaml` pairing records — re-recorded from the merged files.
Blob hashes cannot be hand-merged, and both sides' prose survives on
each side of every pair.
`docs/cordis-catalog/services.md` also regenerated for shifted source
lines and master's new `sessionTitle.rename` entry.
