A persistent marker ensures it is emitted at most once. -- **SessionStart** performs a bounded Substrate search and prints a compact Markdown recall block - when relevant memory is available. - -Each hook is a fresh process, so per-session message digests and one-shot markers are persisted -under the plugin state directory. Capture events are durably spooled before network delivery. - -## Privacy boundary - -The transcript reader captures top-level and sidechain `user`, `assistant`, and `system` records. -Sidechain records carry record/block coordinates and session ancestry. Tool calls and results are -separate text-only messages paired by `tool_call_id`. A paired result receives its tool name; an -orphaned or ambiguous result receives a reason code and no source identity. - -For every captured block, full credential detection runs before the 65,536-byte UTF-8 ceiling. If -a recognized credential occurs anywhere in a block, the whole block becomes content-free. This -prevents a secret from being cut at a former truncation boundary. Binary and media bodies, hidden -reasoning, token usage, billing fields, and arbitrary provider metadata are not captured. - -The shared capture core redacts recognized secrets before persistence and transfer. Redaction is -defense in depth, not proof that arbitrary sensitive prose is absent. Visible prompts and -assistant output can themselves contain confidential material, so configure only a trusted -Substrate server and review its access and retention policy. Failed deliveries remain in a -bounded owner-private local spool. The spool reserves capacity for -boundary events and refuses newest events under pressure instead of evicting older evidence. -`substrate-claude-code status` exposes persistent `evicted`, `quarantined`, `dropped`, and -`duplicates` counters without exposing content. - -## Fail-open behavior - -Hooks always exit with status 0. API failures, malformed hook input, unreadable or truncated -transcripts, corrupt local state, and recall failures do not block or annotate a Claude Code -session. Normal capture hooks write nothing to stdout; optional diagnostics go only to stderr when -`SUBSTRATE_DEBUG` is set. Session-start recall is the sole intentional hook output. - -## Repository map - -- `src/claude_code_memory/` — Claude Code runtime, transcript reader, hooks, recall, MCP server, - and CLI. -- `src/substrate_capture/` — frozen shared capture core used by all host plugins. -- `.claude-plugin/` — plugin and self-listing marketplace metadata. -- `.mcp.json` — stdio MCP server registration. -- `hooks/hooks.json` — Claude Code lifecycle hook registration. -- `commands/` — `/substrate-status` and `/substrate-recall` command prompts. -- `tests/` — shared-core and Claude Code host contract tests with synthetic fixtures. -- `scripts/` — shared-core provenance and publication verification tooling. +The five bounded network operations are `substrate_search`, `substrate_read`, `substrate_query`, +`substrate_ingest`, and `substrate_job_status`. Prefixes avoid MCP namespace collision. Three +Claude operational adapters are additional, not network-parity claims: + +- `substrate_remember` requires `user_requested: true` and reports failure if spool admission fails; +- `substrate_sync` retries the durable queue; and +- `substrate_status` reports content-free local health. + +MCP stdout is JSON-RPC only. Capture hooks normally emit nothing. SessionStart recall is the sole +protocol-approved hook stdout. Human authorization instructions use stderr; CLI machine status +uses JSON stdout. + +## State, update, and removal + +Profile state is below `~/.substrate/claude_code_memory/profiles//` unless an isolated +test relocates the state root. Code update and rollback preserve credentials, spool, cursors, and +consent state because they live outside the plugin directory. + +Remove plugin registration/code separately using the Claude Code plugin mechanism. Local state is +preserved by default. `disconnect --confirm` deletes local custody slots only and does not claim +server revocation. `purge-local-state --confirm --delete-queued-data` separately deletes local +credentials and queued state.

Recovery resumes the journal's one desired logical registration; installer state changes only after Claude reports the exact version, source, enabled state, marketplace, and MCP inventory. Rollback uses the same state machine with the prior snapshot as its desired registration. diff --git a/docs/lifecycle.md b/docs/lifecycle.md index 2ef6df4..fa996de 100644 --- a/docs/lifecycle.md +++ b/docs/lifecycle.md @@ -2,23 +2,24 @@ | Claude signal | Capture meaning | Notes | |---|---|---| -| `Stop` | `turn` | Completed primary turn; new cursor window only. | -| `PreCompact` | `pre_compress` | Durable capture before context compression. | -| `SessionEnd` | `session_end` | A private durable job returns quickly; its worker admits the full unread suffix with no window cap, then commits the boundary last. | -| `SessionStart` | recall injection | Canonical-only recall, pending-job resumption, and a setup instruction.
