`inactive` is populated only by Pi. The skill described it as a Pi
capability but never said what its absence means elsewhere, so an agent
querying a Claude Code session with `includeInactive: true` reads an empty
result as "nothing was abandoned here". Across 43 local Claude transcripts,
20 contained branches off the surviving path, so that reading is wrong far
more often than it is right.
Claude Code and Codex transcripts record no supersession event to attest
from; Kimi records one but the adapter drops those messages while indexing.
The added sentence covers all three without naming them, so it stays correct
if Kimi later marks retracted history instead of discarding it.
Pi cannot be read as another linear JSONL stream. Its history is a tree with
a durable leaf, orphan roots, branch summaries, and two compaction forms, so
the active context is something the format states rather than something line
order implies. The adapter keeps those semantics inside itself and projects
the result into the existing canonical tables.
Sessions are keyed by (normalized header cwd, header id) rather than by path,
because Pi's --session-id lookup is project-local: two projects may reuse an
id, while a move or an identical copy is still one session. Discovery covers
both layouts Pi writes and fingerprints each file by mtime, ctime, size and
inode, so a rewrite that preserves mtime is not read as unchanged.
Abandoned branches are preserved rather than dropped. Visibility becomes
three-state -- visible, inactive, hidden -- and helpers return only visible
rows until includeInactive asks for the superseded path, labeling every row
so a caller knows which it holds. Usage counts all three, because an
abandoned call still spent tokens; message_count reports only the visible
transcript.
A committed MIT-licensed oracle transcribed from Pi 0.83.0 pins the context
algorithms, and a fixed-seed differential runs 512 generated sessions against
it on every test run. Schema changes are additive.
Add @obelisk-apps/cli with the existing build, search, query, and attune contract plus official skill installation.
Separate the docs-only skill artifact, bootstrap installer, release layout, cross-platform CI, and package-level regression coverage.
