The contextBreakdown and contextPressure units carried the full priced
surface, so each session's persisted projection checkpoint grew without
bound. A surface replacement is now priced by the shadow-price event
logged directly before it — compact/summary for compaction, the new
compact/prune from tool-result pruning (priced through the injected
token meter) — and the unit states shrink to a fixed handful of numbers.
Regenerate the persistence/cordis/module/config catalogs.
The merge staged the `--ours` consistency records before the merged prose was
re-recorded, so the committed hashes still describe the pre-merge content and
`verify-translation-pairing` rejects the pair. Re-record all three against
what actually merged.
- An empty replacement catalog is a real catalog: `renderCatalogUpdate()`
publishes zero entries when the last skill disappears, and falling back
would hide that every earlier name was retired.
- The opaque fallback keeps a `form` declaration this version cannot present.
It is the one place a newer or foreign log's declared shape would otherwise
vanish from the UI entirely, since the row marker is also absent there.
- An instruction change with an unrecognized `action` disqualifies the record.
The action decides the word the row shows, so an unknown one would be
presented as loaded or updated.
- The catalog list bounds itself and reports the withheld count. Entry count
is unbounded and the scrollport bounds height, not node count.
- A catalog message keeps content blocks this version does not know, instead
of dropping model-visible content the extensible union may carry.
- `core.md` defines `ContextFormed`, the interface actually carrying the
optional field, beside `ContextForm`.
- The superseded-in-part bullet states the affected clauses as one rule rather
than enumerating them; two rounds of enumeration each missed some, which is
the shape being fragile rather than the list being wrong.
- The note records the one migration case that does not self-heal: an
old-format catalog as the only one, with an empty current view, leaves a
stale catalog nothing replaces.
`contextBreakdown.messageTokens` and `measure().surfaceTokens` answer the same
question in the same heuristic vocabulary, and the panel's composition rows are
only honest while they agree. Each owner carried its own copy of the positional
fold — same pricing, same `{seq, tokens}` node list, same replace-range lookup
and guard, differing only in mutable versus immutable application — so an edit
to either one would have moved the panel away from `measure()` with both sides
still green. The duplication gate caught the shared 62 tokens.
`src/surface-fold.ts` now owns `foldSurfaceTokens`: total, allocation-fresh,
returning the event's price, the next surface, and the signed total delta. The
service assigns that result where it used to prepare a commit closure, which
keeps its validate-before-mutate replay transaction intact — the fold throws
before any state is touched, so a malformed event still fails identically on
every retry. `_prepareSurfaceMutation` and `_estimateSurfaceEvent` go away with
it, and the projection's apply drops to one call.
Covers the identity with a session that appends and then compacts, asserting
the projection figure equals the service surface at each boundary; the test
fails when either side of the fold is perturbed.
- `catalogHistory` validated its durable read. `agent.session.events` is a
JSONL/SQLite seed on resume or fork, and seed validation guarantees only a
source object with a non-empty `kind`; a `skill-catalog` record with missing
or wrongly shaped `entries` threw inside the step listener, failing every
later turn of that session. It is now skipped as an unrecognizable record,
the posture the replaced content digest had, with a regression test over six
malformed shapes.
- The headless keyless smoke still filtered catalogs by the old plugin source,
so the `built-bin-smoke` gate would not have found the catalog message.
- Entries record the published description unescaped. The pseudo-XML escaping
belongs to the `<available_skills>` frame and is applied when rendering it,
so a description containing `<` no longer reaches the card as `<`.
`escapeText` is injective, so republish semantics and the model-facing text
are unchanged.
- Adjacent text blocks join with no separator, matching how provider adapters
flatten them; the body no longer shows a line break the model never saw.
- Provenance fields are bounded like the text: an unknown producer may record
an arbitrarily large value.
- Both readers are all-or-nothing, and the row's form marker reports what
rendered rather than what was declared, so a partly unreadable record cannot
present a confident but incomplete account.
- The catalog body consumes `update` as a replacement notice; the digest
canonicalizes per entry as JSON, since every separator character is itself
legal in a description.
- `core.md` documents the form axis with a `ContextForm` type-equiv block, and
both projections assert the wiring they duplicate.
Assistant footers and the stats line gain TTFT/tok-per-second readings
folded from step timings; context occupancy moves off the stats line onto
a composer ring whose panel shows a heuristic system/tools/messages
breakdown from the new token-meter contextBreakdown session projection.
