Config schema {owner,endpoint,key} -> {group, member, endpoint, key}:
- member (kebab-case slug, validated) is REQUIRED — who this machine
writes as; group is the descriptive team name. CHORUS_GROUP/
CHORUS_MEMBER env, config set --group/--member, doctor + config show
both with sources, NOT-CONFIGURED (78) without a valid member.
- capture stamps author: <member> on every note (_build_note); bootstrap
gains {{MEMBER}} substitution and stamps the seeded anchors; all 8
scaffold templates + canonical frontmatter docs gain author:.
- New missing-author lint check: agent_written notes must carry author:
(bootstrap marker exempt — plugin-owned).
- Lock owner is now <member>-<client>-<pid> (auto_owner); offline-queue
records carry a member field for audit.
- build.py --bake-key bakes group/member/endpoint/key (--group/--member;
member required + slug-validated) for per-member artifacts.
- Manifest -> 2.0.0-alpha.2; rebuilt chorus-memory.plugin.
Verified: 25/25 unit (+config/member checks), scaffold suite (+6 new
member/config assertions), routing-sync, 4 mock e2e (+capture-stamps-
author), run_eval metrics unchanged, +8 phase-2 smoke checks green.

# chorus-memory — v2.0.0-alpha.2
|
||
|
||
> **CHORUS is a group-based fork of [ECHO](https://git.alwisp.com/jason/echo)** — one shared
|
||
> Obsidian vault serving a group of members instead of a single operator. The conversion
|
||
> plan and settled design decisions live in [CHORUS-PLAN.md](CHORUS-PLAN.md). The pre-fork
|
||
> ECHO v1.5.1 state is preserved at the `echo-fork-point` tag. **Phase 1 (mechanical
|
||
> rename) is done**; the body of this README below the fold still describes the
|
||
> inherited single-operator behavior and is rewritten in Phase 5.
|
||
> Deployment endpoint: `https://chorusapi.mpm.to`. CHORUS is a **clean break** from
|
||
> ECHO — fresh vaults on fresh machines; it carries no ECHO back-compat and never
|
||
> reads ECHO configs, state dirs, or vault markers.
|
||
|
||
Persistent memory for Claude / CoWork sessions via the **CHORUS** Obsidian vault, driven over the [Obsidian Local REST API](https://github.com/coddingtonbear/obsidian-local-rest-api). The skill makes direct REST calls through a bundled validated client (`scripts/chorus.py`). The whole toolchain is **pure Python** (stdlib only), so it runs identically on Windows, macOS, and Linux — no bash, no platform-specific `date`.
|
||
|
||
Architected by **Jason Stedwell**. The plugin is **user-agnostic**: it ships no owner, endpoint, or API key — each machine supplies them through a local config file (see [Configuration](#configuration)), so the same plugin works for any group and any vault.
|
||
|
||
This repository (`jason/chorus`) holds the plugin **source** (tracked tree at `chorus-memory.plugin.src/`), the built `chorus-memory.plugin` package artifact (rebuilt on each version bump), and a credential-free A/B `eval/` harness.
|
||
|
||
**1.3 in one line:** the plugin is now **user-agnostic** — the vault owner, endpoint, and API key live in a machine-local config (`~/.claude/echo-memory/config.json`), never in the source; an unconfigured machine **prompts for the key file on load** and installs it with one `config import`. Underneath: one-call `capture` routes and crosslinks memory, `recall` fuses BM25 over note bodies with graph expansion, alias-aware resolution avoids duplicate notes, and a connection-pooled client reads the whole vault concurrently. See the [version history](#version-history) for how it got here.
|
||
|
||
---
|
||
|
||
## Core design principle — the plugin is the single source of truth
|
||
|
||
Everything that defines how ECHO behaves — bootstrap/repair logic, the operating contract, the taxonomy, frontmatter conventions, the routing map, and the canonical note templates — ships **inside the plugin** under `skills/echo-memory/`.
|
||
|
||
The vault itself holds **data only**. There are no `CLAUDE.md` / `BOOTSTRAP.md` / `STRUCTURE.md` / `index.md` control docs in it. The single in-vault control artifact is a one-line marker, `_agent/echo-vault.md`, that records the schema version.
|
||
|
||
Three consequences follow:
|
||
|
||
- **Self-bootstrapping** — point the REST API at an empty Obsidian vault and the plugin stands up the full folder tree, templates, anchors, and marker from its bundled `scaffold/`.
|
||
- **Easy to update** — change behavior by updating the plugin, not by editing files scattered through the vault.
|
||
- **Portable** — the same plugin brings any empty vault online identically; nothing essential depends on files pre-existing in the vault.
|
||
|
||
---
|
||
|
||
## Configuration
|
||
|
||
The plugin ships **no** owner, endpoint, or key — it is user-agnostic. Each machine supplies them through a machine-local JSON config (resolution lives in `scripts/echo_config.py`):
|
||
|
||
- **File:** `~/.claude/echo-memory/config.json` — honors `$CLAUDE_CONFIG_DIR`; the file path itself can be overridden with `$ECHO_CONFIG`. Shape: `{ "owner": …, "endpoint": "https://…", "key": "…" }`.
|
||
- **Per-field env override:** `ECHO_OWNER`, `ECHO_BASE` (endpoint), and `ECHO_KEY` take precedence over the file.
|
||
- **Set up a machine:** `echo.py config import <file>` adopts a config you've been handed; `echo.py config set --owner … --endpoint … --key …` writes one from values; `echo.py config init` scaffolds a blank template to edit; `echo.py config` prints the resolved config (key redacted) and where each field came from.
|
||
- **First run:** an unconfigured machine — or one left on the placeholder template — reports `NOT CONFIGURED` (`echo.py load` prints a banner and exits `78`; other verbs exit `2`; `/echo-doctor` flags it red), and the skill asks the operator for the key file before doing any memory work. The config is **never committed** and **never written into a vault note**; the key stays out of the plugin tree entirely.
|
||
|
||
### Per-user baked-key builds (v1.4.0) — for CoWork
|
||
|
||
The CoWork sandbox does **not** bridge your real `~/.claude` (the mounted `.claude` is the sandbox's own synthetic view), so a config file on your machine can't be read there. The only thing reliably mounted into every session is the **plugin itself**. So for a small set of known users, bake each user's credentials directly into a per-user artifact:
|
||
|
||
```bash
|
||
python build.py --bake-key --from alice-config.json --label alice
|
||
# -> dist/echo-memory-1.4.1-alice.plugin (carries Alice's vault key)
|
||
```
|
||
|
||
Resolution gains a **baked** tier (`DEFAULT_OWNER/BASE/KEY` in `echo_config.py`) that is **empty in source** — the committed tree still ships zero credentials. As of **v1.4.1** a *complete* baked set (endpoint **and** key both present) is **authoritative**: it wins over `ECHO_*` env vars and any `~/.claude` config file and cannot be shadowed, so a delivered per-user artifact "just works" even on a machine carrying a stale or placeholder config. When nothing is baked (the generic published plugin), host behaviour is unchanged — env → config-file → first-run prompt. `build.py --bake-key` fills those constants from a `config.json` (or `--owner/--endpoint/--key`, or `ECHO_*` env). The end user just installs the artifact — **no config file, no per-session paste**, works on desktop and in every CoWork session.
|
||
|
||
> **A baked artifact contains a vault bearer token.** Baked builds land in `dist/` (gitignored) and never touch the shared `echo-memory.plugin` pointer. Deliver each one **directly** to its single user; **never commit, push, or publish it.** Use `--strip-key` (or just a clean source build) for a token-free artifact. Rotation = rebuild + reinstall.
|
||
|
||
Vault paths are addressed **at the root** (e.g. `GET /vault/_agent/context/current-context.md`). Prefer `scripts/echo.py` over raw `curl`: it injects auth, checks HTTP status (a failed write exits non-zero instead of looking like success), retries transient 5xx, verifies PUTs, and does idempotent appends.
|
||

|
||
|
||
## Requirements
|
||
|
||
- **Python 3** in the session environment (stdlib only; invoke as `python3`, or `python` / `py -3` on Windows).
|
||
- Obsidian running on the backend with the Local REST API plugin enabled.
|
||
- HTTPS reachability to `https://echoapi.alwisp.com` from the Claude / CoWork session environment.

**Division of responsibility:** `SKILL.md` owns day-to-day *procedure* (loading order, search-first, triage, scope switching, PATCH rules) and points at the bundled tooling. `references/operating-contract.md` owns the durable, client-independent *principles, safety rules, and concurrency model*. `scripts/routing.json` is the machine-readable source of truth for routing; `references/routing-map.md` is its human-readable authority. The other references are the canonical layout, API, and bootstrap specs.

|
||
## Bundled tooling
|
||
|
||
Executable logic ships under `skills/echo-memory/scripts/`; the agent prefers it over hand-built curl. Everything is **pure Python** (stdlib only) — invoke with `python3` (Windows: `python` / `py -3`).
|
||
|
||
| Tool | Purpose |
|
||
|------|---------|
|
||
| `echo.py` | The validated client + high-level CLI. The network layer is **keep-alive + connection-pooled** (one persistent connection per thread, reused across requests) with a concurrent `read_many()` bulk-GET (`ECHO_WORKERS`, default 8) — so full-vault passes that used to time out finish in under a second. Low-level verbs `get/ls/map/search/put/post/append/patch/fm/bump/delete/lock/unlock/scope/load` inject auth, **check HTTP status** (non-zero exit on ≥400), retry transient 5xx (and reconnect a stale pooled connection), read-back-verify PUT, idempotent whole-line `append`, correct `::` heading targets. High-level ops **`capture/resolve/recall/link`** do the routing/linking for you (see below). |
|
||
| `capture / resolve / recall / link / triage` | The input-reducing layer. **`capture "<title>" --kind <k> [--tags a,b]`** routes via the entity index, stamps **complete** frontmatter (kind-default `status`, kind-seeded `tags`), indexes, auto-links mentioned entities, and writes the Agent-Log line in one call; on an existing entity it appends the **whole body** as a dated block; a strong fuzzy candidate **stops creation** (exit 76 — `--merge-into <slug>` / `--force` resolve it). **`resolve "<mention>"`** → canonical path (alias-aware). **`recall "<query>" [--json]`** → ranked matches + one-hop neighbourhood over entities **and sessions/journal**, fused with freshness + status priors. **`link A B`** → reciprocal `## Related` links. **`triage`** → one-tap inbox routing with an automatic processing-log audit trail. |
|
||
| `echo_index.py` | The **entity index** (`_agent/index/entities.json`): slug→{path, kind, title, aliases, last_seen}. Makes routing/resolve an O(1), alias-aware lookup and supplies the name→path map for linking and recall. `resolve()` matches on slug/title/alias; a `fuzzy_candidates()` "did-you-mean" fallback (1.2) surfaces near-matches for shortened names without auto-merging. Aliases are auto-derived from titles, learned from mentions on update, stored in note frontmatter, and folded back in by `sweep.py`. Rebuilt automatically by `capture` and `sweep.py`. |
|
||
| `echo_links.py` / `echo_ops.py` | Cross-link primitives (parse/add `## Related`, bidirectional linking) and the high-level ops layer (capture/recall/resolve/link/agent-log). |
|
||
| `routing.json` | The **canonical machine-readable** route manifest — one regex pattern per valid destination plus retired paths. The single source of truth for "what may be written where"; `vault_lint.py` enforces it against the vault, `check_routing.py` against the docs. |
|
||
| `vault_lint.py` | Read-only invariant + **graph-health** checker (Vault Health). Tolerant frontmatter parsing, clock injected via `ECHO_TODAY`, exits `3` if the vault isn't bootstrapped. Checks scope-drift, **broken wikilinks, orphan notes, and entity-index drift**. |
|
||
| `sweep.py` | Brings an upgraded vault up to spec: creates `_agent/index/`, rebuilds the entity index from existing notes, symmetrizes `## Related` cross-links (adds only the missing reciprocal direction), and stamps `schema_version`. Dry-run by default; `--apply` to write. |
|
||
| `check_routing.py` | Offline routing-doc consistency check: every vault path named in `SKILL.md` / `routing-map.md` / `api-reference.md` must match a route (or retired pattern) in `routing.json`, and every route must appear in the canonical map. No network. The `test_echo_client.py` suite runs it as a guard. |
|
||
| `bootstrap.py` | Deterministic, idempotent, probe-before-write vault setup/repair (`--dry-run` to preview). Resolves the scaffold relative to itself, so it works from any CWD. |
|
||
| `migrate.py` | Deterministic schema migration. Dry-run by default; destructive steps gated behind `--apply` and printed first. |
|
||
|
||
### Slash commands
|
||
|
||
`/echo-load` (cold-start read), `/echo-save <text>` (route + persist via `capture`), `/echo-recall <query>` (recall a topic's neighbourhood), `/echo-triage` (one-tap inbox routing via `echo.py triage`), `/echo-health` (run the linter), `/echo-sweep` (bring the vault up to spec), `/echo-reflect` (extract→preview→apply durable items from the session), `/echo-doctor` (readiness check: Python, vault reachability, auth, bootstrap/schema, key source) — explicit, reproducible entry points to the procedures below.
|
||
|
||
### Session hooks (v1.5)
|
||
|
||
The plugin ships `hooks/hooks.json`: a **SessionStart** hook runs `echo.py load` and injects the orientation reads as context (cold-start loading no longer depends on the model remembering), and a **Stop** hook nudges **once per substantive session** to run `/echo-reflect` + the session log when nothing was reflected yet (reflection still previews and asks before writing). Both are fail-safe — unconfigured/unreachable vaults degrade to a note, never an error — and use the CoWork path fallback.
|
||
|
||
### Concurrency (shared vault)
|
||
|
||
ECHO is read/written by multiple clients (Claude Code **and** CoWork). Single-line files (`heartbeat/last-session.md`, `current-context.md::Scope`) and append targets (`inbox.md`, `## Agent Log`) assume one writer at a time. Before an overlapping burst of writes, take the cooperative advisory lock (`echo.py lock <id>` → `_agent/locks/vault.lock`, TTL-reclaimable) and release it at session end. Idempotent append and status-checked writes are the second line of defense.

|
||
|
||
## Operating procedures (logic)
|
||
|
||
### Cold-start loading
|
||
|
||
Load memory at the start of any substantive conversation (anything beyond a single quick factual question). One command — `python3 echo.py load` — performs all six orientation reads and prints each labeled section (absent today's-note / inbox show as such, not errors):
|
||
|
||
1. `_agent/echo-vault.md` — the bootstrap marker. `404` → vault not set up (run bootstrap); `200` → check `schema_version` and migrate if older than the plugin's.
|
||
2. `_agent/memory/semantic/operator-preferences.md` — Jason's profile.
|
||
3. `_agent/context/current-context.md` — active scope + Scope History.
|
||
4. `_agent/heartbeat/last-session.md` then `_agent/sessions/` — read the heartbeat pointer first (O(1) jump to the latest log); fall back to the listing's ~5 most recent by reverse lexical sort.
|
||
5. `journal/daily/YYYY-MM-DD.md` — today's note (`404` is fine).
|
||
6. `inbox/captures/inbox.md` — inbox-depth probe for the load-time reconcile.
|
||
|
||
After the batch, **reconcile**: if the inbox holds captures older than ~7 days, surface the count and offer to triage (so triage self-fires rather than waiting to be invoked); and if the active scope diverges from what Jason just asked for, run Scope Switching.
|
||
|
||
If a specific project is in play, follow up with a `search/simple/` across **all** lifecycle subfolders, querying **both the slug and any human title** used in conversation, then read the match at `projects/<lifecycle>/<slug>.md`. Loading is not narrated to the operator.
|
||
|
||
### Inbox triage
|
||
|
||
`inbox/captures/inbox.md` is the catch-all. At session start, GET it; if it holds lines older than ~7 days that were never routed, surface a count once and offer to triage. Accepted items route to their proper home (preference → operator-preferences; project idea → `projects/incubating/`; durable fact → semantic; person fact → `resources/people/`), with the move recorded one-line in `inbox/processing-log/YYYY-MM-DD.md` as an audit trail. Originals aren't deleted unless explicitly asked.
|
||
|
||
### Project lifecycle
|
||
|
||
Projects move through four folders; the folder name and the `status:` frontmatter field **MUST agree** — they are two views of one state. A file in `projects/active/` with `status: on-hold` is broken state.
|
||
|
||
| Folder | `status:` | Meaning |
|
||
|--------|-----------|---------|
|
||
| `incubating/` | `incubating` | Idea captured; not actively worked |
|
||
| `active/` | `active` | Current work (default for anything in motion) |
|
||
| `on-hold/` | `on-hold` | Paused but still tracked; resumable |
|
||
| `archived/` | `archived` | Done, abandoned, or rolled up — not deleted |
|
||
|
||
Promotion = move the file **and** update `status:` in the same change.
|
||
|
||
### Scope switching
|
||
|
||
`_agent/context/current-context.md` tracks one active scope. It is the **most churn-prone state** — several sessions a day across different topics — so without care a new session silently inherits a stale scope (the same failure class as inbox auto-fire). 0.7.1 hardens this three ways:
|
||
|
||
- **Freshness signal** — a `scope_updated:` frontmatter timestamp records when scope last changed.
|
||
- **One-command switch** — `echo.py scope set "<new scope>"` does it atomically: archive the prior scope to `## Scope History` (dated, truncated), replace `## Scope`, and stamp `scope_updated`. (Manual fallback: prepend history → replace `## Scope` → PATCH `scope_updated`; the field must already exist or PATCH returns `400 invalid-target`.) Scope History is trimmed to the last ~10 entries.
|
||
- **Drift detection** — at load the agent runs `echo.py scope show` (prints the scope, its `scope_updated`, and how many sessions have been logged since) and *states + confirms* scope before working, switching if it diverges. As a backstop, `vault_lint.py` flags when ≥ `SCOPE_STALE_SESSIONS` (default 3) session logs postdate `scope_updated` — surfaced in `/echo-health`, so drift is mechanically **evaluable** rather than invisible.
|
||
|
||
### Daily note — Agent Log
|
||
|
||
After substantive activity, append a one-line entry to today's daily note's `## Agent Log`. The procedure is resilient: GET the note → if `404`, PUT it from the template → if `200` but the heading is missing, POST the heading. **Heading detection greps the raw markdown for an anchored `^## Agent Log`** — not the document-map JSON, whose headings are `::`-delimited paths (a bug fixed in 0.4.1 that previously appended duplicate headings).
|
||
|
||
### Session logging
|
||
|
||
At the end of substantive conversations (those producing decisions, artifacts, or commitments), write a session log to `_agent/sessions/YYYY-MM-DD-HHMM-<slug>.md`. **The four-digit HHMM component is canonical, not optional** — it makes filenames lex-sort in true chronological order, which cold-start loading depends on. New writes are validated against `^\d{4}-\d{2}-\d{2}-\d{4}-[a-z0-9-]+\.md$`.
|
||
|
||
### Journal rollups
|
||
|
||
The journal is one append-only time-series stream; rollups are coarser-grained entries on the same timeline, so they live under `journal/` — there is no separate `reviews/` tree.
|
||
|
||
- **Weekly** — opt-in; offered on the first substantive session of a new ISO week, written only if accepted, to `journal/weekly/YYYY-Www.md`.
|
||
- **Monthly** — offered alongside the Vault Health pass on the first session of a calendar month, to `journal/monthly/YYYY-MM.md`.
|
||
- **Quarterly / annual** — manual / on request only, to `journal/quarterly/YYYY-Qn.md` and `journal/annual/YYYY.md`.
|
||
|
||
### Vault Health (monthly)
|
||
|
||
Agent self-maintenance (not a journal entry), written to `_agent/health/YYYY-MM-vault-health.md`. Run `scripts/vault_lint.py` (or `/echo-health`) with `ECHO_TODAY` = the conversation's date so stale/aging math uses one clock. It mechanically asserts: folder↔status mismatch, duplicate slugs across lifecycle folders, wikilinks in frontmatter (swept across all folders), duplicate `## Agent Log` headings, stale active projects (`updated:` > 30 days), aging inbox items (> 14 days), **paths matching no route in `routing.json` or sitting at a retired path**, **frontmatter integrity** (missing required fields, `updated` < `created`, future dates, wikilinks leaking into `source_notes`), **incomplete entity frontmatter** (missing/empty `status`/`tags` per the kind-scoped `KIND_REQUIRED_FM` map — `sweep.py --apply` backfills), and **scope drift** (≥ `SCOPE_STALE_SESSIONS` session logs dated after `scope_updated`). Exit codes: `0` clean · `1` violations · `2` unreachable · `3` not bootstrapped. Findings are reported, not auto-fixed.

|
||
|
||
## Write-safety rules
|
||
|
||
- **Search first (mandatory for new notes).** Before creating any slug-addressed note, `POST /search/simple/?query=<slug>` across the **whole** vault (and search the human title too) — listing one folder misses duplicates elsewhere. On a match: promote/merge from a non-active subfolder, update-in-place in the same folder, or ask which is canonical if elsewhere.
|
||
- **Read before append (idempotency).** `POST` is not idempotent — a retry duplicates lines. Before any POST that adds an entry (inbox, Agent Log, an Observations/Log heading), GET the target and skip if the exact line is already present. (Does not apply to PUT or PATCH-replace.)
|
||
- **Bump `updated:` on substance.** PATCH the frontmatter `updated:` to today after a meaningful content change (status update, decision, scope switch). Skip it for routine log appends — bump on substance, not heartbeat.
|
||
- **Preserve `created:`.** It is the earliest known date the entity was tracked anywhere — never reset it to "today" when merging.
|
||
- **No `[[wikilinks]]` in frontmatter** — YAML parses them as nested lists and they break. Cross-references go in a `## Related` body section. `source_notes` holds plain relative-path strings (backward links to inputs only).
|
||
- **Check the HTTP status (or use `echo.py`).** A `PATCH` to a missing heading returns `400 invalid-target` (40080) and the write is *silently lost*; a transient `503` or an accepted-but-unpersisted `PUT` can do the same. `echo.py` enforces this (exit ≠ 0, retry, read-back verify); raw `curl` must branch on `-w "%{http_code}"`. Treat ≥ 400 as a failed op — surface it, don't continue.

## REST API operations
|
||
|
||
Server `https://echoapi.alwisp.com`, bearer auth, root-addressed paths.
|
||
|
||
| Operation | Method | Notes |
|
||
|-----------|--------|-------|
|
||
| Read file | `GET /vault/<path>` | Raw markdown; `404` = absent |
|
||
| Read heading | `GET /vault/<path>/heading/<H1>::<H2>` | `::`-delimited, URL-encode spaces as `%20` |
|
||
| List dir | `GET /vault/<dir>/` | Trailing slash; returns `{files, folders}` |
|
||
| Document map | `GET` + `Accept: application/vnd.olrapi.document-map+json` | Discover exact heading / block / frontmatter targets |
|
||
| Append | `POST /vault/<path>` | Appends to end-of-file; creates if absent |
|
||
| Create / overwrite | `PUT /vault/<path>` | Auto-creates intermediate directories |
|
||
| Patch section | `PATCH /vault/<path>` | `Operation: append\|prepend\|replace`, `Target-Type: heading\|frontmatter\|block` |
|
||
| Search | `POST /search/simple/?query=<terms>` | Returns `[{filename, score, matches}]` |
|
||
| Delete | `DELETE /vault/<path>` | Only on explicit operator request |
|
||
|
||
**PATCH heading targets must be the full `::`-delimited path from the top-level heading** (e.g. `Operator Preferences::Fact / Pattern`) — a bare subheading name returns `400 invalid-target` (errorCode 40080). GET the document map first when unsure of the exact path, and copy the heading string verbatim.

|

|
||
|
||
## Frontmatter conventions
|
||
|
||
Every note opens with this block (fill what applies; leave the rest empty rather than guessing):
|
||
|
||
```yaml
|
||
---
|
||
type: # daily-note | project | area | concept | reference | person |
|
||
# meeting | decision | review | session-log | working-memory |
|
||
# episodic-memory | semantic-memory | context-bundle | skill | ...
|
||
status: # active | draft | done | archived | complete | incubating | on-hold
|
||
created: # YYYY-MM-DD — earliest known date the entity was tracked
|
||
updated: # YYYY-MM-DD — bumped on meaningful change
|
||
tags: []
|
||
agent_written: # true on agent-generated notes
|
||
source_notes: [] # plain relative paths (backward links) — NEVER [[wikilinks]]
|
||
---
|
||
```
|
||
|
||
`agent_written: true` + a populated `source_notes` is the key signal separating agent-managed content from human-authored content.
|
||
|
||
### operator-preferences.md — Rules vs Observations
|
||
|
||
- `## Fact / Pattern` — promoted, deduped, **timeless** rules (no date prefix).
|
||
- `## Observations` — **timestamped** raw observations (`- 2026-06-06: ...`); the default landing zone for new evidence.
|
||
|
||
Observations are promoted into Fact / Pattern (dropping the date) once a pattern stabilizes, and trimmed to the last ~30 entries.
|
||

||
|
||
## Bootstrap, repair & migration
|
||
|
||
The plugin carries everything needed to stand up a vault in `scaffold/`; there is no dependency on any in-vault control doc. These are deterministic scripts (`scripts/bootstrap.py`, `scripts/migrate.py`, `scripts/sweep.py`), not hand-run curl loops — the prose in `references/bootstrap.md` documents what they do and serves as the fallback.
|
||
|
||
- **Probe** — GET `_agent/echo-vault.md`. `200` → bootstrapped (check `schema_version`); `404` → run a fresh bootstrap.
|
||
- **Fresh bootstrap** (`bootstrap.py`; idempotent, additive — never overwrites): create the folder tree (a one-line README seeds each leaf since Obsidian/git ignore empty dirs) → PUT the 8 templates to their mirrored vault paths → PUT the 3 anchor seeds only if absent (the operator-preferences seed is deliberately empty — no fabricated facts) → PUT the thin vault README → PUT the marker **last** (so the vault is only flagged "set up" once everything is in place) → write a first-run trace (daily note + session log). `--dry-run` previews.
|
||
- **Repair** — `bootstrap.py` again: GET-probes each path and creates only what's missing; malformed files are flagged, never replaced.
|
||
- **Migrations** — `migrate.py` reads the marker's `schema_version`, applies each intervening migration (dry-run by default; `--apply` to perform moves/deletes), and stamps the marker. `0 → 1` removed the old in-vault control docs (`CLAUDE.md` / `BOOTSTRAP.md` / `STRUCTURE.md` / `index.md`); `1 → 2` folded `reviews/` into `journal/` + `_agent/health/`; `2 → 3` adds the `_agent/index/` entity registry.
|
||
- **Bring up to spec** — `sweep.py` back-fills an upgraded vault: builds `_agent/index/entities.json` from existing notes and symmetrizes `## Related` cross-links (dry-run by default; `--apply` to write). Run it after `migrate.py`, or any time `/echo-health` reports index drift.

## Skill triggers
|
||
|
||
| Skill | Triggers |
|
||
|-------|----------|
|
||
| `echo-memory` | "remember that", "save to memory", "what do you know about me", "load my profile", "check my notes", "log this decision", "add to my inbox" — and proactively at the start of substantive conversations |
|
||
|
||
---
|
||
|
||
## Safety rules (operating contract)
|
||
|
||
- Do not fabricate facts, relationships, or prior decisions.
|
||
- Do not mass-restructure the vault unless explicitly asked.
|
||
- Do not delete notes unless deletion is explicitly requested and clearly safe.
|
||
- Never store secrets or API keys inside a vault note.
|
||
- Default to additive updates and explicit status changes over destructive edits.
|
||
- Write in **third person** about Jason ("Jason prefers X"). Do not cross-write with other vaults (Bryan's `goldbrain` is separate).
|
||
|
||
If the API returns a connection error, timeout, or `502` (usually Obsidian / the REST plugin not running), tell Jason once that the vault is unreachable and proceed without memory — don't retry repeatedly.

## Eval metrics (v1.5.1, 2026-07-03)
|
||
|
||
From the credential-free harness (`eval/run_eval.py` against the deterministic mock — no live vault; full detail in `eval/results/latest.json`). Baseline = pre-1.5 behavior: keyword substring ranking over entity notes only, no gate.
|
||
|
||
| Metric | v1.5.1 | pre-1.5 baseline |
|
||
|---|---|---|
|
||
| Retrieval recall@5 / MRR (8-query gold set) | **1.00 / 1.00** | 0.75 / 0.75 |
|
||
| Queries answerable only from sessions/journal | **2/2** | 0/2 (not in corpus) |
|
||
| Freshness: live note outranks stale archived twin | **yes** | no |
|
||
| Duplicate notes created (3 renamed-entity captures) | **0** (gate blocks) | 3 |
|
||
| Legitimate captures wrongly blocked | **0** | 0 |
|
||
| Silent write failures (4 fault scenarios) | **0** (failures loud) | — |
|
||
| Offline writes lost / duplicated on re-flush | **0 / 0** (3/3 queued + landed) | — |
|
||
|
||
## Version history
|
||
|
||
| Version | Highlights |
|
||
|---------|-----------|
|
||
| **1.5.1** | **Duplicate-gate precision.** Live use caught the gate blocking a decision note because it shared the single vault-common token "echo" with an archived project (min-normalized scoring gives any single-token entity a 1.0 match). New `gate_candidates()` blocks only on **same-kind** candidates (cross-kind name collisions — a decision titled after its project — warn instead), and a **lone shared token blocks only when unique to that entity** (vault df == 1); multi-token overlaps still block. Advisory warnings (`fuzzy_candidates`) unchanged; exit-76/`--merge-into`/`--force` unchanged. +5 tests; verified against the live vault both ways (false positive creates cleanly, true lookalike still gates). |
|
||
| **1.5.0** | **Six-improvement pass: retention, routing, and self-firing memory.** (1) **Capture-update keeps the whole body** — the update path previously appended only the first line of a multi-line body (silent data loss); now the full body rides under the dated bullet. (2) **Frontmatter completeness** — capture stamps a kind-default `status` and kind-seeded `tags` (`--tags` enriches); `fm` is create-or-replace (missing keys are surgically inserted instead of 400-failing); `vault_lint` gains a kind-scoped `incomplete-frontmatter` check; `sweep --apply` backfills (fixes the 18/71-notes field-audit drift, one data source: `KIND_STATUS`/`KIND_REQUIRED_FM`). (3) **Pre-write duplicate gate** — a strong fuzzy candidate stops `capture` (exit 76 + candidates) before the duplicate exists; `--merge-into <slug>` updates the canonical entity, `--force` overrides. (4) **Recall corpus + ranking** — sessions and journal notes join the BM25 corpus (down-weighted); scores fuse freshness (half-life on `updated:`) and status (`active` boosted, `archived` demoted); hits show `updated:`/`status:`; `recall --json`; recall-index schema 2 (auto-rebuilds). (5) **Session hooks** — SessionStart auto-loads memory into context, Stop nudges reflection once per substantive session; fail-safe, CoWork-fallback-aware. (6) **One-tap triage** — `echo.py triage` lists the inbox structured, then classifies → previews → routes accepted items via `capture` with automatic processing-log audit lines; `--json` also lands on `link`/`scope show`. +22 mock end-to-end tests; all suites green. |
|
||
| **1.4.2** | **CoWork sandbox path resilience.** In a remote CoWork sandbox `${CLAUDE_PLUGIN_ROOT}` can point at a host path the sandbox can't reach (`/var/folders/…`) while the plugin is mounted under `…/mnt/.remote-plugins/…`, so script invocations failed until the agent found the real path by hand. SKILL.md and all eight slash commands now resolve the scripts dir with a fallback — prefer `${CLAUDE_PLUGIN_ROOT}`, else locate the mounted copy under `/sessions/*/mnt/.remote-plugins/*/…` — reused via `$ECHO`/`$LINT`/`$SWEEP`/`$SDIR`. On a normal host the primary path always wins (no behaviour change). `echo-health`/`echo-sweep` `allowed-tools` broadened to match the resolved invocation. (The scripts never hardcoded a path — root cause is the harness env var — but the plugin now self-heals.) |
|
||
| **1.4.1** | **Baked credentials now win unconditionally.** A per-user baked artifact could still be prompted for credentials on install: the baked `DEFAULT_*` tier was lowest priority, so a stale `ECHO_*` env var or a leftover/placeholder `~/.claude/echo-memory/config.json` shadowed the baked key — even an unedited `"<placeholder>"` value beat it, flipping `is_configured()` to false and triggering the first-run "ask the operator" flow despite valid baked creds. `echo_config.load()` now treats a **complete** baked set (endpoint + key both present) as authoritative — it wins over env vars and the config file and cannot be shadowed; the generic (unbaked) plugin keeps its env → file → first-run flow. New `baked_complete()`; `source()` reports `baked-in (plugin)`. Per-user artifacts rebaked; manifest → 1.4.1. |
|
||
| **1.4.0** | **Per-user baked-key builds — zero-touch CoWork install.** The CoWork sandbox doesn't bridge your real `~/.claude`, but the plugin itself is mounted every session — so credentials can travel *inside* the artifact. `echo_config` gains a baked tier (`DEFAULT_OWNER/BASE/KEY`, **empty in source** so the committed tree still ships zero credentials). New `build.py --bake-key --from <config.json> [--label <name>]` substitutes one user's owner/endpoint/key into those constants, producing a per-user artifact that needs **no config file and no per-session paste** (values may also come from `--owner/--endpoint/--key` or `ECHO_*` env). Baked builds default to `dist/` (gitignored) and never touch the shared `echo-memory.plugin` pointer; `--strip-key` force-blanks the constants for a guaranteed token-free build. `config show`/`doctor` report the baked source. |
|
||
| **1.3.1** | **Prompts for the key on load.** A fresh or just-upgraded machine has no config yet, so the plugin detects that and asks for it instead of failing opaquely. `echo_config.is_configured()` treats a missing **or still-placeholder** config as unconfigured; `echo.py load` prints a `NOT CONFIGURED` banner and exits `78` (other verbs exit `2`; `/echo-doctor` reports it red). New **`echo.py config import <file>`** adopts a config you've been handed — it validates the file and writes `~/.claude/echo-memory/config.json`. `SKILL.md` gains a **First run** step: on the not-configured signal the agent asks the operator for their key file and installs it, then proceeds. One-time per machine — the config lives in `~/.claude/`, so later plugin updates don't disturb it. |
|
||
| **1.3.0** | **User-agnostic — owner/endpoint/key out of the source.** The plugin previously baked in an API key and hard-coded the endpoint; both are gone. Owner, endpoint, and key are now **machine-local**, resolved by the new `echo_config.py` from `~/.claude/echo-memory/config.json` (env `ECHO_OWNER`/`ECHO_BASE`/`ECHO_KEY` override per field); `echo_secrets.py` removed. New `echo.py config` subcommand (`show`/`init`/`set`). All personal details (owner, role/employer), the live endpoint, and the literal key were **stripped** from the plugin source, references, commands, and eval harness — the only name that remains is the architect credit. A placeholder `config.template.json` is provided for new users/vaults. Routing manifest unchanged; offline test suites pass. Manifest → 1.3.0. |
|
||
| **1.2.0** | **Entity-resolution overhaul — fewer duplicate notes.** Resolution was exact-match only, so a shortened or expanded mention (e.g. "echo memory" for the `echo`-slugged active project) returned *no match* and the writer created a parallel note. Now `resolve()` matches on slug / title / **aliases**, with a `fuzzy_candidates()` "did-you-mean" fallback ranked by shared distinctive tokens (guarded by `echo_quality` so generic words like "data"/"api"/"the" can't drive a match). Aliases are **auto-derived from titles** (hyphen/space/case variants), **learned from mentions** on update, and stored in each note's `aliases:` frontmatter (the Obsidian-native home), then folded back into the entity index by `sweep` — so the graph gets better at resolution over time, while exact-match safety still prevents wrong auto-merges. Ships with the v1.1 connection-pool + concurrency work. 33 automated tests pass across Win/macOS/Linux; linter clean. See the [performance brief](echo-memory-performance-brief.html). |
|
||
| **1.1.0** | **Performance / network-layer rebuild — "from timing out to sub-second."** Full-vault scripts (`sweep.py`, `vault_lint.py`, recall rebuild) were making hundreds of *serial* requests, each opening a fresh TLS connection and re-reading every note 2–3×; on the constrained agent sandbox a single pass exceeded the ~120 s tool timeout and was killed mid-run, dropping the session/thread. Three structural fixes in `echo.py`: (1) **connection reuse (keep-alive)** — one persistent pooled connection per thread, reused across requests instead of a TCP+TLS handshake per file (**~4.5× faster per request**, the dominant win; benefits load/capture/recall for free); (2) **concurrent bulk reads** — new `read_many()` fans GETs across a thread pool (`ECHO_WORKERS`, default 8) for ~2× on full-vault scale; (3) **single-pass shared cache** — each note fetched *once* and reused across all passes (~2–3× fewer requests), eliminating `sweep`'s per-link-target re-fetch storm. Net effect: a full-vault pass that used to **time out now finishes in <1 s** (vault_lint 0.90 s, sweep plan 0.85 s on 186 notes); the practical change is fails → completes. Stdlib-only, no new dependencies. |
|
||
| **1.0.0** | Schema 4. **"Memory you can trust and retrieve."** (H1) **Hybrid recall** — local BM25 over note bodies fused with decayed graph expansion (`echo_recall.py`, `_agent/index/recall-index.json`), maintained on `capture`, rebuilt by `sweep`; replaces keyword-only recall. (H2) **Offline durability** — write verbs queue to a local write-ahead outbox on an outage and report "queued"; `flush` (+ flush-on-`load`) replays idempotently and **re-bases to the current endpoint**; `load` degrades to a last-known-good read cache (`echo_queue.py`). (H3) **Concurrency** — `vault_lock` + `atomic_index_update` (lock + fresh re-read-merge) close the concurrent-`capture` entity-loss race (`echo_concurrency.py`). (H4) **Trust** — higher-fidelity PATCH mock + offline/reflect/patch-semantics suites gated in GitHub Actions across Win/macOS/Linux × Py 3.10/3.12. (H5) **Reflection capture** — `echo.py reflect` / `/echo-reflect` extract→dedup→preview→apply durable items (`echo_reflect.py`). (M1) **Secret hardening** — key resolves env → `~/.echo-memory/credentials` → deprecated fallback; `write-key` CLI; token scrubbed from docs (see [API-KEY-SETUP.md](API-KEY-SETUP.md)). (M2) confident auto-linking + slug-collision guard (`echo_quality.py`). (M3) `echo.py doctor` / `/echo-doctor` + heartbeat-less `load` fallback. (M4) `capture --json` / `--dry-run`. (M5) manifest → 1.0.0, `.gitignore`. |
|
||
| **0.3.0** | Source promoted from zip-only to a tracked tree (`echo-memory.plugin.src/`); `.plugin` becomes a build artifact. All 7 skill-improvement items applied: search-first before writes, resilient daily Agent Log, `created:` semantics, project lifecycle + folder↔status rule, canonical HHMM session filenames, read-most-recent-N sessions, `source_notes` defined as backward links. |
|
||
| **0.4.0** | Efficiency + robustness pass: parallel cold-start loading, idempotent POST (read-before-append), doc-map-before-first-PATCH, scoped `updated:` bump, Inbox Triage, Scope Switching, monthly Vault Health, Rules-vs-Observations split, formal deprecation of `decisions/by-project/`, heartbeat pointer. |
|
||
| **0.4.1** | Bugfix: daily-note Agent Log heading detection now greps raw markdown for `^## Agent Log` instead of the `::`-delimited doc-map JSON (which never matched and appended duplicate headings). Added Scope Switching cold-start test harness. |
|
||
| **0.5.0** | Self-bootstrap + control-logic-in-plugin. Plugin becomes the single source of truth: bundled `scaffold/` (8 templates, 3 anchor seeds, thin vault README, marker) bootstraps an empty vault with no external/local-path dependency. New `operating-contract.md` (principles + safety from the old in-vault `CLAUDE.md`); `bootstrap.md` rewritten as a portable bootstrap/repair/migrate manifest. Cold-start probe moved from `/vault/BOOTSTRAP.md` to `_agent/echo-vault.md` (carries `schema_version`). Live vault migrated to data-only. |

| **0.5.1** | Routing-doc consistency pass: decision-mirror heading unified to `## Key Decisions`; stale `Current status` PATCH examples corrected to `Status`; vault-layout inline project example refreshed to the real template. All 17 `projects/active/` notes normalized losslessly to the canonical template heading set; `android-mqtt-shell` moved to `incubating/` (was broken `status: upcoming` in active). Plugin repackaged (21 files). |

| **0.6.0** | Schema 2. **#8 Inbox auto-fire:** the Loading procedure adds an inbox-depth GET and a load-time *Reconcile* step (inbox triage + scope-drift), so triage self-fires. **#10 Routing:** `reviews/` retired — weekly/monthly/quarterly/annual rollups fold into `journal/{weekly,monthly,quarterly,annual}/`, vault-health moves to `_agent/health/`; new `references/routing-map.md` is the complete audited endpoint→logic map. **Recs:** heartbeat pointer operationalized (read first at load, written at session end); new `scripts/vault_lint.py` mechanically checks vault invariants. Dead refs pruned (`archive/`, `_agent/outputs/`, `resources/source-material`). Migration `1 → 2` in `bootstrap.md`. |

| **0.7.0** | Schema 2 (unchanged layout). Hardening pass — gave the prose-and-curl skill an executable spine. **S2** `scripts/echo.py`: one validated client wrapping every verb with auth, HTTP-status checking (failed writes exit non-zero instead of looking like success), one bounded retry on 5xx, read-back-verified PUT, and idempotent `append`. **S3** `scripts/routing.json`: canonical machine-readable route manifest; `vault_lint.py` enforces it (flags unknown/retired paths). **S4** deterministic `scripts/bootstrap.py` + `scripts/migrate.py` (idempotent, dry-run, probe-before-write; fixes the old CWD-relative `@scaffold/...` empty-body bug). **S5** cooperative advisory lock (`_agent/locks/vault.lock`) + documented multi-writer model. **M1/M2/M5** linter rewrite: real YAML parsing, injected clock (`ECHO_TODAY`), exits `3` (not "clean") on an un-bootstrapped vault, plus routing-membership + frontmatter-integrity checks. **M3** status-check guidance throughout. **M4** four slash commands (`/echo-load`, `/echo-save`, `/echo-triage`, `/echo-health`). Added a credential-free A/B `eval/` harness (mock REST API + fault injection): isolates a **−76% generated-token** I/O layer and **4 → 0 silent write failures** vs 0.6. |
|
||
| **0.7.1** | **Scope-drift fix.** Scope is the most churn-prone state (several sessions/day) and had no freshness signal, so sessions silently ran under stale scope (same failure class as #8). Added a `scope_updated:` frontmatter timestamp (maintained automatically), an `echo.py scope show` / `scope set` command (atomic switch: archive prior → replace → stamp), and a `vault_lint.py` **drift check** (flags when ≥ `SCOPE_STALE_SESSIONS`, default 3, session logs are dated after `scope_updated`) — making drift mechanically *evaluable* via `/echo-health`. Tightened the SKILL load-reconcile to *state and confirm* scope every session and switch before working. (Also fixed a bash nested-quote parse bug found while building `scope`, where `show` could fall through into `set`.) |
|
||
| **0.8.0** | **Cross-platform + reliability pass.** Ported the entire toolchain from bash to **pure Python** (`echo.py`, `vault_lint.py`, `bootstrap.py`, `migrate.py`) so it runs identically on Windows/macOS/Linux — removes the bash and macOS-only `date` dependencies (the lock's TTL parse previously degraded silently on unsupported platforms); stdout is UTF-8-safe so non-ASCII output can't crash a legacy console. **Correctness:** `append` now skips only on an exact **whole-line** match (a substring no longer causes a false skip that silently drops a write); the advisory lock is **read-back-confirmed** after PUT so a racing writer backs off instead of proceeding under a false lock. **Routing consistency (`check_routing.py`):** mechanically verifies the routing docs against `routing.json` in both directions, run as a guard in `test_echo_client.py`; added the missing locks / leaf-README / decision-template rows to the canonical map. **Usability:** new one-call `echo.py load` cold start; `SKILL.md` slimmed — the duplicated raw-curl recipes now live only in `api-reference.md` (the *nix fallback). |
|
||
| **0.9.0** | Schema 3. **Recall + routing intelligence — five layered features aimed at less input to route and richer links to recall.** (1) **Entity index** (`_agent/index/entities.json`): a slug→{path,kind,title,aliases} registry so routing/`resolve` is an O(1), alias-aware lookup instead of a fuzzy search (dedup at the source). (2) **`recall`**: search + one-hop expansion along `## Related` and `source_notes` — returns a topic's connected neighbourhood, not an isolated note. (3) **Bidirectional auto-linking**: `link A B` and link-on-`capture` keep the graph symmetric. (4) **`capture`**: one call that routes, stamps canonical frontmatter, indexes, auto-links mentioned entities, and writes the Agent-Log line — collapsing the whole write discipline. (5) **Graph-health checks** in `vault_lint.py`: broken wikilinks, orphan notes, entity-index drift. Plus **`sweep.py`** to bring an existing vault up to spec (build the index + symmetrize links + stamp schema), `migrate.py` 2→3, and `/echo-recall` + `/echo-sweep` commands. New modules `echo_index.py` / `echo_links.py` / `echo_ops.py`; offline + mock-integration tests (`eval/test_features.py`). |
