Turn steps carry `file.write` changes next to their + `conversation.append`, so the walk aborted on hash order and silently + emptied the wire `kept` list about one derive in four on sessions with + tool-created files. Steps are now classified by their `conversation.*` + change specifically. Regression coverage: a looped unit test, file + mutations in the proptest turn generator, and a real captured pi + session (`test-fixtures/pi/compacted-real.jsonl`) with a looped + stability test. +- **`toolpath-claude`** (fix): projected compact summaries now carry + `isVisibleInTranscriptOnly: true` — without it the Claude TUI renders + the entire summary text inline on resume instead of collapsing it + (verified in claude 2.1.216). +- **`toolpath-copilot` 0.2.0**: context compaction is now **observed** + (first-hand capture at 1.0.68, `test-fixtures/copilot/compacted-real.jsonl`) + and mapped both directions. A successful `session.compaction_complete` + becomes the typed `Item::Compaction` (`summary` ← `summaryContent`, + `pre_tokens` ← `preCompactionTokens`; wholesale — Copilot reports + removed-message counts, not surviving ids, so there is no kept run); + `success: false` stays a generic event, as does the + `session.compaction_start` bookkeeping marker. The projector emits the + observed start/complete pair back. Turn parents now stitch through + boundaries so the head-ancestry walk crosses the compaction in order. + Docs de-staled: `session.compaction_*` rows are `[observed, 1.0.68]`, + compaction token semantics resolved, checkpoint mirroring + (`checkpoints/NNN-*.md`) recorded. +- **`toolpath-codex`**: resume fidelity, verified in the real codex TUI + (0.144.4). The projector follows every `compacted` line with the + `event_msg`/`context_compacted` marker the TUI renders its "Context + compacted" row from, and places the opening `turn_context` at its + native position (after leading system-envelope messages, immediately + before the first real prompt). `path resume` now mints a deterministic + fresh session id (reusing the source id made imports ambiguous and let + the thread-row INSERT OR REPLACE clobber the native session) and + titles the registered thread from the first non-envelope user message + instead of the `` XML. The 2026-07 payload + (window-id chain, encrypted summary in `replacement_history`, a + prefix-keep the suffix-anchored contract cannot represent) is + documented as deliberate loss; the empty `message` now normalizes to + no summary. Real capture checked in as + `test-fixtures/codex/compacted-real.jsonl`. +- **`toolpath-claude`**: resume-rendering fidelity, verified in the real + Claude TUI (2.1.216). An assistant entry whose content is + `[{"type":"text","text":""}]` aborts the transcript renderer (a + resumed session lost every ❯ prompt and the Compacted indicator); the + projector now re-emits fully empty assistant turns as the empty + thinking block real Claude writes, and `path p import claude` / + `path share` derive with thinking included. Events (attachments, + system entries) emit inline at their item position instead of + regrouping at the end of the file; the caveat entry keeps `isMeta`; + the reader stream-parses each line so a mid-write flush boundary + (two objects on one physical line) no longer drops entries. +- **`toolpath-pi`**: model/thinking state survives resume, verified in + pi 0.72. `model_change` / `thinking_level_change` / `label` entries + map to typed `Item::Event`s (previously discarded — a resumed + projection lost its model selection), and the projector threads the + chain's model context into assistant `provider`/`api` fields. +- **`toolpath-convo`**: the item-space `expand_kept` passes through + events on the parent chain, matching its documented step-space twin. +- **`path-cli`**: `path p import` prints an `events preserved:` count + by type, so an unmapped source encoding (like Copilot's compaction + pair, which shipped unnoticed as `compactions=0`) is visible at + import time. New `docs/agents/tui-drift-check.md` records the + per-harness-release verification loop and the versions each harness + was last verified against. + +## Compaction kept contract: anchor-based + executable round-trip invariants — 2026-07-16 + +The `Compaction` kept contract is now anchor-based. The IR carries +`kept_from` — the id of the oldest prior turn surviving verbatim into the +post-compaction window — and the surviving set is *defined* as the +contiguous parent-chain run from that anchor up to the boundary, computed +by the new shared `toolpath_convo::expand_kept`. The wire `kept` array +(on the `conversation.compact` structural change) keeps its shape (turn-id +strings) but tightens its meaning: always a contiguous run, oldest first, +whose first element is the anchor. Compaction provenance is a closed typed +set — there is deliberately no catch-all `extra`; native detail richer +than the contiguous run (e.g. Claude's replay-pinned messages) is not +carried, and round-trips are lossy beyond these fields. + +- **`toolpath-convo`**: `Compaction.kept` (id list) → `kept_from` (anchor); + shared `expand_kept`. Steps whose + `parents` were rewired by derive-splicing now stamp `source_parent` + (string|null — the pre-splice source parent) on their + `conversation.append`/`conversation.compact` structural change, so + `extract_conversation` restores the original linkage exactly instead of + guessing it back from the event chain. +- **`toolpath-convo`**: new `testing` module with the round-trip contract + as executable checks — `check_view_invariants` (e.g. a `kept_from` + anchor must resolve to a non-empty run on the boundary's ancestry) and + `assert_fixpoint` (derive → extract → derive is stable) — plus a + proptest suite asserting unique derived step ids, derive → extract → + derive stability, and byte-identical-replay drops on randomized views. +- **`toolpath-claude`**: projection follows Claude's wire convention of + chaining the first post-boundary entry through the synthetic summary + (boundary ← summary ← first-post-entry) — IR parents pointing at the + boundary are redirected to the emitted summary. Reads recover the + boundary anchor from the native preserved tail (`kept_anchor` walks the + boundary's parent chain through `preservedMessages.uuids`; a native set + that doesn't form a contiguous tail ending at the boundary is wholesale + at view granularity). Projection writes `preservedMessages.uuids` as the + `expand_kept` run. +- **`toolpath-pi`**: Pi's `firstKeptEntryId` can name a non-turn entry + (`model_change`, folded tool result); it now resolves to the first turn + at-or-after the anchor instead of dangling, and projection passes the + next turn's id so a projected anchor always names an entry that exists. +- **`toolpath-opencode`**: projected message timestamps are forced + strictly increasing (`monotonize_times`) — the reader orders by + `time_created`, so a boundary stamped later than the message after it + would move on re-read. +- **`toolpath-codex`**: projection guards mixed groups — when a group's + members carry per-step attributions (which already advance the + cumulative counter by the full group total), the group-final's bare + `token_usage` no longer advances it again, so a re-read doesn't + attribute double the real spend. +- **`toolpath-md`**: transcript rendering matched only the newest + `agent-coding-session` kind URI, silently downgrading v1.0.0/v1.1.0 + documents to the generic DAG layout; it now matches all three. +- **`toolpath-convo`**: validating against real compacted sessions (10 + live Claude/opencode sessions driven through invariants, stability, and + the fixpoint oracle) caught two extract gaps the fixtures missed: + session-level `files_changed` was rebuilt only from per-step + `file.write` changes, dropping every file the provider recorded at + session level (now recovered from `meta.extra` first); and a + harness-synthetic assistant turn (actor `tool:`, e.g. + Claude's API-error entries) lost its `` model marker and + re-derived as `agent:unknown` (now restored from the step actor). The + proptest generator now covers synthetic and model-less assistant turns + plus session-level `files_changed`. +- **`toolpath-opencode`**: a real manual `/compact` hosts the boundary on + a user message containing only the compaction part; that message emits + no turn, so later turns whose native `parentID` named it dangled. Such + parents now redirect to the item standing in for the skipped message — + the boundary itself. +- **Real-session cross-harness matrix** (`cross_harness_matrix.rs`): a new + opt-in `matrix_translation_real_sessions` test drives the full + translation matrix from real local sessions (`TOOLPATH_REAL_MATRIX` + env var, `harness:locator` specs). Running it over every session on a + dev machine (26 sources × 7 targets, then a 298-session native sweep) + surfaced and fixed: + - **`toolpath-claude`**: all-zero `usage` blocks (synthetic API-error + entries) decoded as measurements instead of `None`, breaking + cross-harness accounting; and extract lost the `` model + marker (see above). + - **`toolpath-gemini`**: same all-zero-decodes-as-`None` gap for + degenerate `{input: 0}` records on aborted generations. + - **`toolpath-copilot`**: the reader dropped empty-text, tool-less + assistant turns that carry real `outputTokens` (aborted responses), + un-conserving session totals; and the projector re-derived `view` + `view_range` from `offset`/`limit` only, so an already-native input + lost its range on the second cycle. + - **`toolpath-opencode`**: native user rows carry no `parentID`, so IR + turn chains broke at every user message — the reader now synthesizes + the linear parent, which also keeps foreign kept anchors resolvable. + - **`toolpath-pi`**: the `-init` virtual root Pi writes as + the first entry's `parentId` survived as a dangling parent; it now + resolves to `None`. + - **`toolpath-convo`**: the multi-edit file-write fallback copied + provider-shaped `edits` JSON onto the wire that `FileMutation` can't + represent, so one round-trip silently degraded the document; the raw + diff (and the `tool.invoke` input) already carry that information. + - Matrix invariants tightened to the true contract: token-usage + survival is conservation of assistant input/output totals (turn + folding and zero↔`None` wire limits make sequence equality wrong), + and `kept_run_may_inflate` documents that a strictly linear target + (opencode) may retain intervening turns a source boundary skipped — + growth allowed, shrink or anchor loss still fails. + +Crates bumped: `toolpath` 0.8.0, `toolpath-convo` 0.12.0, +`toolpath-claude` 0.13.0, `toolpath-gemini` 0.7.0, `toolpath-codex` +0.7.0, `toolpath-opencode` 0.6.0, `toolpath-cursor` 0.3.0, `toolpath-pi` +0.7.0, `toolpath-git` 0.7.0, `toolpath-github` 0.7.0, `toolpath-dot` +0.6.0, `toolpath-md` 0.8.0, `path-cli` 0.16.0, `toolpath-cli` 0.16.0. +The four dependents of `toolpath` alone (`git`/`github`/`dot`/`md`) bump +because their published versions declare `toolpath` ^0.7.0, which would +resolve a second `toolpath` next to 0.8.0 in a registry build; `path-cli` +and `toolpath-cli` skip to 0.16.0 because 0.15.0 is already published +with different content. + +## Extract: undo the event splice when rebuilding wire parents — 2026-07-07 + +- **`toolpath-convo`**: `derive_path` splices events and compactions onto the + head's ancestry, which re-parents neighboring steps through event steps — + ids that don't exist on the wire (Claude's headerless preamble/snapshot + lines carry no `uuid`, so nothing can chain through them). + `extract_conversation` now resolves a turn's or compaction's parent past + event-derived steps back to the nearest turn/compaction ancestor, so + projectors write valid wire chains: a re-exported Claude session's first + message keeps `parentUuid: null` instead of naming a synthesized + `claude-preamble-N` step, and messages after a snapshot line chain onto + the real prior message.

Sub-agent files are folded into `DelegatedWork` with populated `turns` (unlike `toolpath-claude`, whose sub-agent turns live in separate session files and stay empty). See `docs/agents/formats/gemini.md` for the full format reference. -- Provider-specific extras convention: `Turn.extra` and `WatcherEvent::Progress.data` use provider-namespaced keys (e.g. `extra["claude"]`, `extra["gemini"]`). `toolpath-claude` populates `Turn.extra["claude"]` from `ConversationEntry.extra`; `toolpath-gemini` populates `Turn.extra["gemini"]` with the full `tokens` struct, per-thought metadata, and tool-call status. This lets trait-only consumers access provider metadata without importing provider types. +- The conversation IR (`toolpath-convo`) is a **closed typed set** — no catch-all `extra`/passthrough fields on `Turn`, `Compaction`, or any other IR type. `Turn.extra` was removed on main (`0452f61`, "stop smuggling source-format details through the IR") and `Compaction` never gets one; provider detail either earns a typed optional field or is accepted as lossy. Native-layer catch-alls (e.g. `toolpath-claude`'s `ConversationEntry.extra` serde-flatten) are fine — they represent the *source format*, not the IR. `WatcherEvent::Progress.data` (a live event stream, not the IR) still uses provider-namespaced keys. - Shared derivation: `toolpath-convo` provides a provider-agnostic `ConversationView → Path` mapping via `toolpath_convo::derive_path`. New conversation providers should build on it rather than re-implementing the mapping. -- Path kinds: `toolpath::v1::PathMeta.kind` is an optional URI naming a hosted kind spec; URIs are immutable and semver-versioned. The only one defined so far is `https://toolpath.net/kinds/agent-coding-session/v1.1.0` (constant `toolpath::v1::PATH_KIND_AGENT_CODING_SESSION`; `…_V1_0_0` names the superseded URI); every conversation → `Path` derivation sets it via the shared `toolpath_convo::derive_path` or each provider crate's own. Carried through the JSONL form via `PathOpen.meta` and `PathMeta` patch lines. Spec sources live in `site/kinds///{index.md,schema.json}` (schema.json is a symlink into `crates/path-cli/kinds/`, which `path p validate` bundles — both versions) and publish under `https://toolpath.net/kinds/`; the registry index is `site/kinds/index.md`. RFC: "Document Kind". JSON Schema: `$defs/pathMeta`. +- Path kinds: `toolpath::v1::PathMeta.kind` is an optional URI naming a hosted kind spec; URIs are immutable and semver-versioned. The only kind defined so far is `agent-coding-session`, currently at `https://toolpath.net/kinds/agent-coding-session/v1.2.0` (constant `toolpath::v1::PATH_KIND_AGENT_CODING_SESSION`; `…_V1_1_0`/`…_V1_0_0` name the superseded URIs); v1.2.0 adds the `conversation.compact` step type for context-compaction boundaries on top of v1.1.0's message-level token accounting, and the earlier v1.1.0 and v1.0.0 URIs stay registered (their schemas kept in `path-cli`'s `BUNDLED_KINDS`) and documented for backward compatibility. Every conversation → `Path` derivation sets it via the shared `toolpath_convo::derive_path` or each provider crate's own. Carried through the JSONL form via `PathOpen.meta` and `PathMeta` patch lines. Spec sources live in `site/kinds///{index.md,schema.json}` (schema.json is a symlink into `crates/path-cli/kinds/`, which `path p validate` bundles — all versions) and publish under `https://toolpath.net/kinds/`; the registry index is `site/kinds/index.md`. RFC: "Document Kind". JSON Schema: `$defs/pathMeta`. - Token accounting (kind v1.1.0): two keys on `conversation.append`/`Turn`, both optional. `token_usage` = "the total for a message" (on the group's final step; `Σ` over a path = session total). `attributed_token_usage` = "this step's own attributed spend", populated only where the source genuinely reports per-step spend (its own key, so the sum is unaffected; remainder = group total − Σ attributed, computed not stored). One provider message can span several steps (Claude writes one JSONL line per content block); `Turn.group_id` groups them. `toolpath-claude` fills `group_id` from `message.id` and takes the **field-wise-max** group total (line order not trusted). Claude's per-line `usage` is a cumulative *streaming snapshot* (Anthropic streaming API: `message_start` seeds output near 0, `message_delta` is cumulative), NOT a per-block cost — so Claude emits no `attributed_token_usage`; the projector re-expands the total onto every line. `toolpath-codex` differences the cumulative `total_token_usage` (dedup-safe: never sum `last_token_usage` — Codex re-emits it stale; openai/codex #14489), attributes each per-call delta to the step it follows, and derives the round total from those attributions. pi/opencode decode all-zero wire counters as `None`. Never stamp a cumulative counter, a repeated message total, or zero-filled placeholders onto a step; never derive attribution from Claude's streaming snapshots. - Token usage `breakdowns` (kind v1.1.0, additive): an optional third key on `TokenUsage` — a decomposition of a top-level class into named sub-classes, keyed by class (e.g. `"output"`), inner map sub-class → tokens (e.g. `breakdowns["output"]["reasoning"] = 243`). INFORMATIONAL ONLY: **never summed into any total** (the parent class already counts those tokens, so the session-total guarantee is untouched); invariant `Σ(inner) ≤ parent`; omitted when empty; rides both `token_usage` and `attributed_token_usage`. Per-provider reality: **Gemini** reports `thoughts` (reasoning) as an additive sibling that the derivation used to **drop** (under-counting output) — it's now folded into `output_tokens` *and* recorded as `breakdowns["output"]["reasoning"]`, with the projector un-folding it on the reverse path for a lossless round-trip (`Some(0)` preserved as a real Gemini-3 zero-reasoning signal). **OpenCode** folds `reasoning` into output and records the same breakdown. **Codex** differences `reasoning_output_tokens` (⊆ output, cumulative) into `breakdowns["output"]["reasoning"]` on both per-step `attributed_token_usage` and per-round `token_usage`. **Claude** records no breakdown (its JSONL `usage` doesn't itemize thinking tokens). -- Pi provider: `toolpath-pi` reads Pi session JSONL from `~/.pi/agent/sessions/`. Sessions use a tree (id/parentId) in a single file, and may link to a parent file via `parentSession` in the header. The tree is preserved as a DAG in the derived `Path`. -- Codex provider: `toolpath-codex` reads Codex CLI rollout files from `~/.codex/sessions/YYYY/MM/DD/rollout-*.jsonl`. Sessions are date-bucketed (not project-keyed). File-change fidelity is excellent — Codex's `patch_apply_end` events carry either the unified diff (for updates) or the full file content (for adds), so the derived `Path` gets a real `raw` perspective on every file artifact. See `docs/agents/formats/codex.md` for the full format reference. -- Copilot provider (**preview, schema reverse-engineered**): `toolpath-copilot` reads the GitHub Copilot CLI (`@github/copilot`) `events.jsonl` stream from `~/.copilot/session-state//` (root overridable via `COPILOT_HOME`; also globs the legacy `history-session-state/`). Sessions are global (id-keyed dirs), not project-keyed. The `events.jsonl` schema is **undocumented** but was **verified against a first-hand capture at `copilotVersion` 1.0.67**: envelope is `{type, data, id, timestamp, parentId}`; cwd + git (branch/remote/`headCommit`) live under `session.start`'s `data.context` (primary; `workspace.yaml` is the fallback, parsed by a tolerant key-scan with no YAML dep); tool calls carry `toolCallId`/`toolName`/`arguments` with results under `result.content`; `assistant.message` carries `reasoningText` (→ thinking) and per-message `outputTokens` (summed for the session total). The reader stays deliberately tolerant (payload inline / under `data` / under `payload`; multiple key spellings; unknown events preserved as `ConversationEvent`s). `subagent.*` and `session.shutdown` (`tokenDetails`) are now observed via a real feature-elicit capture at 1.0.68; event types not yet observed (`skill.invoked`, `hook.*`, `abort`, compaction) and the `checkpoints/` format remain unverified. Wired into the CLI both directions — forward (`path p import/list/show copilot`, `path share`) and reverse via `CopilotProjector` (`path p export copilot`, `path resume`; the projector emits `events.jsonl` in the observed shape, remaps foreign tool names via `native_name`, and — for resume — writes `session-state//` + a `session-store.db` `sessions` row, INSERTing only a fresh id). **Verified in copilot 1.0.67**: a projected session loads and resumes in the real `copilot --resume`. Reaching that mapped the loader's writer contract (UUID `id`/`parentId`, offset-ISO timestamps on every event, `turnId`/`messageId` on turn-scoped events, non-empty `toolCallId`, full `session.start` shape, and `subagent.*` fields `agentName`/`agentDisplayName`/`agentDescription`/`toolCallId`) — documented with verbatim rejection messages in `docs/agents/formats/copilot-cli/writing-compatible.md`; verified on a small session and a 5817-event sub-agent session. Also validated in isolation by the cross-harness conformance matrix (`crates/path-cli/tests/cross_harness_matrix.rs`, fixture `test-fixtures/copilot/`) + a round-trip test. File fidelity is **Codex-grade**: `edit`/`create` completes embed the real file-state diff inline (`result.detailedContent`), which upgrades the arg-derived `FileMutation.raw_diff`; sub-agents are `task` tool calls with thin `subagent.*` markers sharing the `toolCallId` (delegations pair by it). Session token totals take `output` from the summed per-message `outputTokens` and merge input/cache totals from `session.shutdown`'s `tokenDetails` (Copilot reports only `output` per-message, so input+cache would otherwise be dropped); no per-turn attribution. Full format reference + verification checklist: `docs/agents/formats/copilot-cli/`. +- Compaction boundary (kind v1.2.0): the `conversation.compact` step type — a context-compaction boundary recorded as its own step between the turns it separates (turns after the boundary parent on it, so the `head`-ancestry walk crosses it in order). `structural` fields are all optional but `type`: `trigger` (`auto`|`manual`), `summary`, `pre_tokens`, and `kept` (ids of prior turns surviving verbatim into the post-compaction window — always a contiguous parent-chain run, oldest first, whose first element is the anchor; empty = wholesale). Compaction provenance is this **closed typed set** — no catch-all `extra`; native detail richer than the contiguous run (e.g. Claude's replay-pinned messages) is deliberately not carried and round-trips are lossy beyond these fields. The IR carries the anchor as `Compaction.kept_from`; `toolpath_convo::expand_kept` expands it to the run. Steps whose parents were rewired by derive-splicing also carry `source_parent` (string|null) on their `conversation.append`/`conversation.compact` structural change. It is not a turn (no `text`/`role`/`tool_uses`); `step.actor` is `tool:`. Populated by each provider's `Item::Compaction` derivation and projected back to harness markers. +- Pi provider: `toolpath-pi` reads Pi session JSONL from `~/.pi/agent/sessions/`. Sessions use a tree (id/parentId) in a single file, and may link to a parent file via `parentSession` in the header. The tree is preserved as a DAG in the derived `Path`. `model_change`/`thinking_level_change`/`label` entries map to typed `Item::Event`s (chain links — `expand_kept` passes through them) and project back; the projector threads the chain's model context into assistant `provider`/`api` so pi restores the resumed session's model (verified in pi 0.72). Compaction `details`/`fromHook` are deliberate loss. +- Codex provider: `toolpath-codex` reads Codex CLI rollout files from `~/.codex/sessions/YYYY/MM/DD/rollout-*.jsonl`. Sessions are date-bucketed (not project-keyed). File-change fidelity is excellent — Codex's `patch_apply_end` events carry either the unified diff (for updates) or the full file content (for adds), so the derived `Path` gets a real `raw` perspective on every file artifact. Compaction (2026-07 payload): `compacted.message` is empty — the summary lives encrypted in `replacement_history` (unrecoverable) and the surviving turns are a prefix-keep the suffix-anchored `kept_from` contract cannot represent, so the boundary derives wholesale with no summary; the projector follows every `compacted` line with the `event_msg`/`context_compacted` marker the TUI renders its "Context compacted" row from, and places the opening `turn_context` right before the first real prompt (codex titles a backfilled session from the first user message; the env-context XML must not win). `path resume` mints a deterministic fresh session id — reusing the source id made imports ambiguous and clobbered the native session's `threads` row (all verified in codex 0.144.4). See `docs/agents/formats/codex.md` for the full format reference. +- Copilot provider (**preview, schema reverse-engineered**): `toolpath-copilot` reads the GitHub Copilot CLI (`@github/copilot`) `events.jsonl` stream from `~/.copilot/session-state//` (root overridable via `COPILOT_HOME`; also globs the legacy `history-session-state/`). Sessions are global (id-keyed dirs), not project-keyed. The `events.jsonl` schema is **undocumented** but was **verified against a first-hand capture at `copilotVersion` 1.0.67**: envelope is `{type, data, id, timestamp, parentId}`; cwd + git (branch/remote/`headCommit`) live under `session.start`'s `data.context` (primary; `workspace.yaml` is the fallback, parsed by a tolerant key-scan with no YAML dep); tool calls carry `toolCallId`/`toolName`/`arguments` with results under `result.content`; `assistant.message` carries `reasoningText` (→ thinking) and per-message `outputTokens` (summed for the session total). The reader stays deliberately tolerant (payload inline / under `data` / under `payload`; multiple key spellings; unknown events preserved as `ConversationEvent`s). `subagent.*`, `session.shutdown` (`tokenDetails`), and **context compaction** are now observed via real captures at 1.0.68: a successful `session.compaction_complete` becomes the typed `Item::Compaction` (`summary` ← `summaryContent`, `pre_tokens` ← `preCompactionTokens`; wholesale — Copilot reports removed-message counts, not surviving ids), `success: false` and the `session.compaction_start` bookkeeping marker stay generic events, the projector emits the observed pair back, and the summary mirrors to `checkpoints/NNN-*.md`. Event types not yet observed (`skill.invoked`, `hook.*`, `abort`, mode/plan changes) remain unverified. Wired into the CLI both directions — forward (`path p import/list/show copilot`, `path share`) and reverse via `CopilotProjector` (`path p export copilot`, `path resume`; the projector emits `events.jsonl` in the observed shape, remaps foreign tool names via `native_name`, and — for resume — writes `session-state//` + a `session-store.db` `sessions` row, INSERTing only a fresh id). **Verified in copilot 1.0.67**: a projected session loads and resumes in the real `copilot --resume`.

Full format reference + verification checklist: `docs/agents/formats/copilot-cli/`. - opencode provider: `toolpath-opencode` reads a SQLite database at `~/.local/share/opencode/opencode.db` (opened read-only). Each session's messages and 12 typed part variants (text, reasoning, tool, step-start/-finish, snapshot, patch, file, agent, subtask, retry, compaction) land as one step per message with tool invocations attached. File diffs come from a sibling bare git repo at `snapshot//[]/` via `git2` tree↔tree diffs — opencode respects the user's `.gitignore`, so changes under gitignored paths fall back to tool-input-derived structural changes with no `raw` perspective. Project id is the SHA of the repo's first root commit. See `docs/agents/formats/opencode.md` for the full format reference. - Cursor (IDE) provider: `toolpath-cursor` reads Cursor.app's global `state.vscdb` SQLite (opened read-only) at `~/Library/Application Support/Cursor/User/globalStorage/state.vscdb` (macOS; `~/.config/Cursor/...` on Linux). Composers, bubbles, and content-addressed file blobs are stored as key-prefixed rows in the `cursorDiskKV` table (`composerData:`, `bubbleId::`, `composer.content.`) plus a `composer.composerHeaders` index blob in `ItemTable`. The full tool-dispatch enum (53 entries, ids 0–63) is extracted from the workbench bundle into `TOOL_TABLE` for round-trip-correct numeric ids — projector-written composers load back into Cursor.app's UI with the right tool rendering. The cursor-agent CLI uses a different per-chat protobuf store at `~/.cursor/chats///store.db` that this crate does not yet parse — that's deferred to a future `toolpath-cursor-cli` companion. See `docs/agents/formats/cursor.md` for the full format reference. - Format references for the agent on-disk formats we derive from live at `docs/agents/formats/`. The Claude Code format (`~/.claude/projects/…` JSONL) gets the deepest treatment — twelve focused docs at `docs/agents/formats/claude-code/` covering envelope, entry types, tools, session chains, compaction, writing-compatible JSONL, a linear walkthrough, and a version-keyed changelog. Sibling single-file references: `codex.md`, `gemini.md`, `opencode.md`.

Schema

schema.json
+
+ +A Toolpath path whose `meta.kind` is this URI records an AI coding conversation. It is an ordinary path with the extra structure described here. `head`-ancestry, dead ends, signatures, and `base` all behave as in the [base format](/format/). + +Every such path comes from one place: the shared `ConversationView → Path` derivation in `toolpath-convo` (`derive_path`), which the provider crates (`toolpath-claude`, `toolpath-gemini`, `toolpath-codex`, `toolpath-opencode`, `toolpath-cursor`, `toolpath-pi`) all call. The field shapes below are therefore exact. The only producer-specific parts are the contents of a tool's `input`, the diff text in a change's `raw`, and the value (not the meaning) of `group_id`. + +Constraints apply by structural `type`, not by artifact key: a `change` entry is checked only when its `structural.type` is one named here, and extra properties never make a path invalid. [`schema.json`](./schema.json) encodes the rules; apply it alongside the base schema. The URI is immutable. Later revisions ship under a new version URI. + +**Changed from [v1.1.0](/kinds/agent-coding-session/v1.1.0/):** adds the [**compaction boundary**](#compaction-boundary) step type (`conversation.compact`). v1.1.0's `group_id` and [group accounting](#group-accounting) carry forward unchanged. v1.2.0 documents are structurally valid v1.1.0 documents; the new version exists so consumers can rely on the compaction step type. + +## The turn payload + +One entry in a turn's `change` map has `structural.type` of `"conversation.append"`. Find it by that type: the artifact key is producer-specific, formed as `://` from the harness in `meta.source` (e.g. `claude-code://…`, `gemini-cli://…`, `codex://…`, `opencode://…`, `cursor://…`, `pi://…`). + +Its `structural` object always carries: + +| Field | Type | Meaning | +| ------ | ------ | ------------------------------------------------------------------ | +| `type` | string | the literal `"conversation.append"` | +| `role` | string | `"user"`, `"assistant"`, `"system"`, or a producer-specific string | +| `text` | string | the visible prose; present even when empty (`""`) | + +It may also carry any of the following, present only when the turn has them: + +| Field | Type | Meaning | +| ------------------------ | -------------- | ---------------------------------------------------------------------------------------------------------------------------------------- | +| `thinking` | string | the model's reasoning text | +| `group_id` | string | groups the steps derived from one source accounting unit (see below) | +| `tool_uses` | array | tools the agent invoked (shape below) | +| `token_usage` | object | the group's token counts (shape and rule below) | +| `attributed_token_usage` | object | this step's own attributed spend, when known (see below) | +| `stop_reason` | string | why the model stopped (`end_turn`, `tool_use`, …) | +| `delegations` | array | sub-agent work spawned from this turn (shape below) | +| `environment` | object | working environment at this turn (shape below) | +| `source_parent` | string \| null | the pre-splice source parent (null for a source root), when derive-splicing rewired the step's `parents` through intervening event steps | + +The model identifier is not on the change. It lives in `step.actor` (`agent:`) and `meta.actors`. There is no provider-specific blob: every field the derivation captures is one of those listed above. + +### `group_id` + +The provider's identifier for the **source accounting unit** these steps were derived from — Claude Code's `message.id` (`msg_…`) for one split message, Codex's round `turn_id` for one round (which may itself contain several messages). It is a **grouping key, not a step identifier**: when a producer derives several steps from one accounting unit (Claude Code writes one JSONL line per content block; a Codex round emits a commentary turn plus a final turn), every sibling step carries the same `group_id`. A step without a `group_id` is its own group of one. The stored value is the provider's verbatim id; only its _meaning_ (which unit it names) is provider-specific. + +### Group accounting + +How `token_usage` on steps relates to the source's accounting units: + +1. `token_usage` records a group's spend — a **per-group amount, never a cumulative session counter**. +2. Within a run of consecutive steps sharing a `group_id` (document order), the run's **last step carries the group's total `token_usage`, verbatim from the source**. In this version, the run's other steps carry none. +3. A step without a `group_id` is its own group and carries its own `token_usage` (when the source records one). + +Consequence: **summing `token_usage` over a v1.2.0 path's steps yields the session totals.** Consumers need no dedup heuristics. (JSON Schema cannot express the once-per-run rule, so it is normative prose, enforced by producer test suites.) + +`token_usage` has **one meaning everywhere it appears: the total for a group**. A step without a `group_id` is a one-step group, so its `token_usage` is that group's total (which is also its own spend — the two coincide for a group of one). Within a multi-step group, the total sits on the final step. Interpreting a value never requires reading the rest of its group: the key tells you it is a total, and `group_id` on the same payload tells you which group it totals. Per-step spend, when the source has it, rides a separate [`attributed_token_usage`](#per-step-attribution-attributed_token_usage) key — never `token_usage`. When a source format offers both a group total and a finer breakdown (Claude's `usage.iterations`, opencode's per-part `step-finish` tokens), `token_usage` carries the total; the breakdown is subordinate detail and does not ride `token_usage`. + +### Per-step attribution: `attributed_token_usage` + +Some sources expose, per step, the spend attributable to that step alone — distinct from the group total. Where a producer has it, the step carries an **`attributed_token_usage`** object (same shape as [`token_usage`](#token_usage)) holding _this step's own share_. It is **optional and orthogonal to `token_usage`**: whether a number is a group total or a step share is structural — the key it sits under — never positional. This is the rule that lets per-step accounting be added by any producer at any time without a new kind version. + +How it relates to the group total: + +- Within a `group_id` group, `Σ attributed_token_usage` over the group's steps is the group's attributed spend. The **unattributed remainder** — anything the source could not pin to a step — is _computed_ by a consumer as `group's token_usage − Σ group's attributed_token_usage`; it is never recorded, so stored values stay verbatim source observations and source inconsistencies stay visible. +- For a group where the source attributes everything (e.g. Codex, where each step is a separate API call and the per-call delta is reported directly), the remainder is zero and `Σ attributed_token_usage == token_usage`. +- A group with no per-step data carries no `attributed_token_usage` at all — only the group total. Producers must not fabricate a split. + +A producer populates `attributed_token_usage` only when the source genuinely reports per-step spend. Among current producers, **Codex does** (its `token_count` events carry a per-call delta). **Claude does not**: its per-content-block `usage` values are cumulative streaming snapshots stamped at flush time, not per-block costs, so deriving a split from them would be fabrication — Claude-derived steps carry the group total only. + +`Σ token_usage` over a path's steps is unaffected by `attributed_token_usage` (they are separate keys), so the session-total guarantee above always holds. A consumer wanting per-step cost reads `attributed_token_usage` where present and falls back to the group total otherwise. + +### `tool_uses` + +Each element is an object: + +| Field | Type | Notes | +| ---------- | -------------- | ---------------------------------------------------------------------------------------------------------------------------------- | +| `id` | string | provider-assigned invocation ID | +| `name` | string | provider tool name (`Read`, `Bash`, `edit`, …) | +| `input` | any | tool arguments; shape is producer-specific | +| `category` | string \| null | Toolpath's classification: `file_read`, `file_write`, `file_search`, `shell`, `network`, `delegation`, or `null` when unrecognized | +| `result` | object | `{ "content": string, "is_error": boolean }`, when the result landed in the same turn | + +`id`, `name`, `input`, and `category` are always present (`category` may be `null`); `result` is optional. + +### `token_usage` + +| Field | Type | Notes | +| -------------------- | --------------- | ------------------------------------------------- | +| `input_tokens` | integer \| null | always present | +| `output_tokens` | integer \| null | always present | +| `cache_read_tokens` | integer | only when the source records it | +| `cache_write_tokens` | integer | only when the source records it | +| `breakdowns` | object | only when the source itemizes a class (see below) | + +Values follow the [group accounting](#group-accounting) rule above. + +`breakdowns` is an **optional, informational** decomposition of a top-level class into named sub-classes. It is keyed by the class being broken down (e.g. `"output"`); each value is a map of sub-class → tokens (e.g. `{ "output": { "reasoning": 450 } }`). Breakdowns are **never summed into any total** — the parent class already counts these tokens; a breakdown only says _how_ that class divides. Invariant: **`Σ(inner) ≤` the parent class's value**. The field is omitted entirely when empty. The same shape and rule apply on `attributed_token_usage`.

Each projector renders the run in its own form.

First looks for a project skill that already covers launching the app; otherwise falls back to built-in patterns per project type (CLI, server, TUI, Electron, browser-driven, library).\n- init: Initialize a new CLAUDE.md file with codebase documentation\n- review: Review a pull request\n- security-review: Complete a security review of the pending changes on the current branch","skillCount":14,"isInitial":true,"names":["deep-research","update-config","keybindings-help","verify","code-review","simplify","fewer-permission-prompts","loop","schedule","claude-api","run","init","review","security-review"]},"type":"attachment","uuid":"5fcf4cd0-01fa-4214-8bb4-04bc14897100","timestamp":"2026-06-10T18:40:50.731Z","userType":"external","entrypoint":"sdk-cli","cwd":"/private/var/folders/jk/4rycn96j1rdbj2mz275yv11m0000gn/T/toolpath-elicit.7HDqFK/claude","sessionId":"c07efcc2-c931-4e4e-bc2c-b14ded596469","version":"2.1.170","gitBranch":"HEAD"} +{"type":"ai-title","aiTitle":"Execute coding tool exercise tasks","sessionId":"c07efcc2-c931-4e4e-bc2c-b14ded596469"} +{"parentUuid":"5fcf4cd0-01fa-4214-8bb4-04bc14897100","isSidechain":false,"message":{"model":"claude-opus-4-8","id":"msg_01WiAWgtEy3NtR8tZpGumwRT","type":"message","role":"assistant","content":[{"type":"thinking","thinking":"","signature":"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"}],"stop_reason":"tool_use","stop_sequence":null,"stop_details":null,"usage":{"input_tokens":2486,"cache_creation_input_tokens":3217,"cache_read_input_tokens":15334,"output_tokens":368,"server_tool_use":{"web_search_requests":0,"web_fetch_requests":0},"service_tier":"standard","cache_creation":{"ephemeral_1h_input_tokens":3217,"ephemeral_5m_input_tokens":0},"inference_geo":"not_available","iterations":[{"input_tokens":2486,"output_tokens":368,"cache_read_input_tokens":15334,"cache_creation_input_tokens":3217,"cache_creation":{"ephemeral_5m_input_tokens":0,"ephemeral_1h_input_tokens":3217},"type":"message"}],"speed":"standard"},"diagnostics":null},"requestId":"req_011Cbv4x18Wh753z3Yu2MazU","type":"assistant","uuid":"e924d226-863e-4dd3-b45e-d9be12e0e995","timestamp":"2026-06-10T18:40:56.773Z","userType":"external","entrypoint":"sdk-cli","cwd":"/private/var/folders/jk/4rycn96j1rdbj2mz275yv11m0000gn/T/toolpath-elicit.7HDqFK/claude","sessionId":"c07efcc2-c931-4e4e-bc2c-b14ded596469","version":"2.1.170","gitBranch":"HEAD"} +{"parentUuid":"e924d226-863e-4dd3-b45e-d9be12e0e995","isSidechain":false,"message":{"model":"claude-opus-4-8","id":"msg_01WiAWgtEy3NtR8tZpGumwRT","type":"message","role":"assistant","content":[{"type":"text","text":"I'll work through these in order, thinking out loud before each tool call.\n\n**Step 1:** List the current directory.

The summary below covers the earlier portion of the conversation.\n\nSummary:\n1. Primary Request and Intent:\n The user requested a structured walkthrough of a fixed set of 10 ordered tasks designed to exercise every common tool category (list, write, read, edit, find/glob, grep/search, error-handling on a missing file, shell script execution, sub-agent dispatch, and a final summary). Explicit constraints and rules stated by the user:\n - \"Stay inside the current working directory — do not touch anything outside it.\"\n - \"Take the steps in order.\"\n - \"Briefly think out loud before each tool call so the reasoning is captured.\"\n - Tool-selection rule (verbatim intent): \"if a step mentions a dedicated tool *and* that tool is available to you, use it; otherwise, use whatever shell-based equivalent you have (e.g. `ls`, `cat`, `sed`, `find`, `grep`). Don't skip steps because a dedicated tool is missing.\"\n The 10 steps: (1) list files; (2) write `notes.md` with two exact lines; (3) read `notes.md` back; (4) change \"scratch\" to \"fixture\"; (5) find files starting with \"note\"; (6) search contents for \"fixture\"; (7) attempt to read nonexistent `does-not-exist.txt` (must fail and be reported, not swallowed); (8) write `count.sh` printing 1–5 and run it confirming 5 lines; (9) dispatch a sub-agent with the exact instruction \"Count the words in `notes.md` and report the number.\" and quote its reply; (10) summarize in 2–3 sentences what was done, then stop without asking for further work.\n\n2. Key Technical Concepts:\n - Dedicated-tool-vs-shell-fallback selection logic.\n - Claude Code tool set: Write, Read, Edit, Bash, Agent (sub-agent dispatch), ToolSearch (for deferred tools), Skill, Workflow.\n - Sub-agent dispatch via the Agent tool with subagent_type (used \"Explore\", a read-only search agent).\n - Bash utilities as fallbacks: `ls`, `find -maxdepth 1 -name`, `grep -rn`, `wc -l`, `bash
