One schema-bump release (recall-index schema 3, entity-index schema 2; old
recall indexes rebuild automatically, no vault migration):
- Local-first recall index: the live BM25 index lives in the machine state dir
(keyed by endpoint hash); capture's upkeep is a zero-network atomic file
write, no advisory lock — replacing the O(vault) GET/PUT-whole-index round
trip per write. The vault copy is a snapshot (sweep + session-end) used to
seed fresh machines / catch up after another client swept
(ECHO_RECALL_SYNC_HOURS, default 24). The read path never PUTs the vault.
- Incremental sweep: entity + recall meta carry 16-char content hashes;
`sweep --fast` fetches only new/gone/hash-missing notes plus a rotating
weekday shard (--all-shards forces everything); deletions drop from both
indexes; index-only so no --apply gate. `load` auto-runs it past
ECHO_FAST_SWEEP_DAYS (7); doctor reports index freshness. Obsidian-side
edits now reach the indexes without manual maintenance.
- Stemming + alias expansion: echo_stem.py (conservative Porter-lite, unit-
tested families + over-stemming guards) applied at index AND query time;
a query fuzzy-matching an entity folds its title/alias vocabulary into the
BM25 query at half weight — expansion can only boost docs containing the
terms. capture hashes the note's FINAL content (auto-link reordered first).
Eval gold set 8 -> 14 queries (6 paraphrases): recall@5/MRR 1.00/1.00 vs
keyword baseline 0.75/0.79. +3 unit tests, +10 e2e; test harnesses now isolate
ECHO_STATE_DIR. All seven suites green.

Found at 2.2.0 deploy: the Connect flow attempts Dynamic Client Registration and
offers no custom-header option. Minimal single-user OAuth layer queued as 2.2.x
backlog next to the nightly vault backup. Claude Code / desktop / CoWork header
auth unaffected.

ECHO as 14 typed MCP tools (streamable HTTP, stateless JSON, bearer auth, open
/health) wrapping the 2.1.1 *_op cores in-process:
- mcp-server/app.py: FastMCP app; duplicate gate + offline queueing surface as
DATA (merge_into/force are parameters, never blind retries); recall packs
excerpts into budget_chars by score; get_note is traversal-guarded with
section/max_chars; patch_note enriches invalid-target errors with the note's
actual headings; log_session wraps the session-end bundle (heartbeat-last);
ECHO_MCP_TOOLS=core exposes only the six daily drivers; all MCP writes
serialize in-process; startup fails fast on missing env.
- Dockerfile (legacy format — no BuildKit on the CI runner), python:3.12-slim,
healthcheck probes 127.0.0.1; .dockerignore keeps the context lean.
- .gitea/workflows/docker-build.yml: standard image build; PORT redeploy
trigger targets the echo-mcp container explicitly (repo name is echo).
- deploy.unraid.yml: br0/auto-IP, /data volume, vault adjacency
(ECHO_BASE=http://10.2.0.35:27123), secrets as SECRET: refs.
- SKILL.md: prefer the echo_* tools when the connector is present; CLI recipes
stay as the fallback. Spec header marked BUILT (tool count corrected to 14).
- eval/test_mcp_server.py: e2e over real streamable HTTP (health/auth/
initialize/tools-list + capture->gate->merge->recall->log_session); skips
cleanly when the SDK is absent. All seven suites green.

Internal refactor per docs/MCP-SERVER-SPEC.md §4; CLI output and exit codes
unchanged (wrappers reproduce them from the envelopes):
- echo_ops: capture_op/resolve_op/link_op — duplicate gate and offline queueing
are data (action: duplicate-gate + candidates; queued: true); the --json
stdout-swallow hack is deleted (helper chatter -> stderr inside the cores);
capture_op takes body_text= directly (the MCP path, no temp file).
- echo_recall.recall_op — one structured result backs prose and --json.
- echo_triage.list_op/route_op, echo_reflect.apply_op,
echo_session.session_end_op — call capture_op internally, count gate outcomes
from envelopes.
- echo.scope_show_op/scope_set_op/load_op (+ shared _load_gather), and
echo_doctor.run_op (checks as data).
New eval/test_ops_api.py asserts the contract for every core: envelope shape
AND stdout purity (a stray print would corrupt an MCP response stream). All six
suites green. The 2.2 server build now starts directly at the app layer.

Three independently useful changes (IMPROVEMENT-PLANS #1/#3/#7), no schema changes:
- load --brief: token-budgeted cold-start digest (facts full, last-10 observations,
scope+freshness, last session's key sections, agent-log lines, inbox count;
ECHO_LOAD_BUDGET ~8000 chars, lowest-priority-first trimming). SessionStart hook
injects the brief form; /echo-load keeps the full dump. All load reads (+ the
sessions listing, which also feeds the heartbeat fallback) fetched in parallel.
- Offline capture durability: a fully-offline capture queues the WHOLE op as one
semantic record; flush replays it through capture so routing/gate/aliasing re-run
against the current index; a gate stop on replay is kept + flagged
(needs_attention, surfaced by flush and load), never landed blind; update-path
and ensure_daily_log writes ride safe_request; same-args captures dedupe.
- session-end: one call, one lock — session log -> agent-log line -> reflect
proposals (gate-aware) -> optional scope set -> heartbeat LAST as the commit
marker; dry-run default; ECHO_NOW pins HHMM; validation runs before any write.
Stop hook nudge names the command and recognizes it as reflected.
- Fix: main() now catches the __main__ twin-module EchoError (via RuntimeError +
.code) so helper-module errors exit with their intended codes, not tracebacks.
+19 e2e checks; all suites green. Plans renumbered: MCP container is 2.2.

Memory behavior unchanged; the major signals a distribution/install break.
- Legacy commands/ directory DELETED (skills-only; the 1.6.0 skills were verified
on desktop + CoWork and already took precedence). Pre-skills clients install
1.6.0 from the release history.
- Artifact policy: the repo tracks only the echo-memory.plugin pointer; the 15
historical versioned zips leave the tree (git history retains them); versioned
builds ship as Gitea release assets, one release per v<version> tag, starting
v2.0.0. .gitignore: *.plugin except the pointer.
- README: post-2.0 repository layout; "packaging for other agent runtimes" note
(ports are build targets from the canonical tree, never a second source tree).
- ROADMAP-2.0 items ticked; manifest -> 2.0.0.
All suites green (25/25 unit + 4 e2e suites); artifact rebuilt skills-only
(79 entries, no commands/).

All four checks pass on the baked 1.6.0 artifact (skills register + precedence,
allowed-tools, operator-only sweep/triage, CoWork $ECHO fallback). Caveat noted:
allowed-tools globs match literal script names, not the "$ECHO" variable form —
re-confirm on the Claude Code CLI if that surface becomes routine.

Seeds archive/notes/README.md and asserts vault_lint flags retired-path —
fails against the pre-1.6.0 linter, passes with the retired-first check.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Skills migration: each of the eight slash commands gains a skills/<name>/SKILL.md
twin (same invocation name, byte-identical body). Per-skill allowed-tools
pre-authorize the resolved python3/python/py -3 invocations + the CoWork ls
fallback probe; disable-model-invocation: true makes /echo-sweep and /echo-triage
operator-only. Docs-confirmed: a same-name skill takes precedence over the legacy
command, so commands/ coexists until its scheduled 2.0 deletion. The $ECHO
path-resolution dedupe is resolved as not-supported (skill dirs are
self-contained; no cross-skill snippet sharing).
Lint fix: vault_lint.py checks retired patterns BEFORE routes, so a seed README
inside a retired tree (archive/...) flags retired-path instead of being absolved
by the permissive leaf-readme route. New end-to-end regression test seeds
archive/notes/README.md (fails pre-fix, passes now).
plugin.json: version 1.6.0, homepage + repository -> git.alwisp.com/jason/echo.
All suites green: 25/25 client unit tests (incl. routing-sync guard), feature,
reflect, offline-queue, PATCH-semantics. Artifact rebuilt (87 entries, both
formats); pointer refreshed.

Learned removing the retired archive/ and _agent/outputs/ trees: DELETE
cannot remove directories; the last-file deletion leaves empty folders
that the REST listing 404s (falsely reading as gone) while Obsidian
still shows them — manual cleanup required. Noted in api-reference.md
(Deleting Files) and linked to the TODO-1.6 retired-tree lint item.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Vault sanity check found archive/ and _agent/outputs/ (retired/unrouted
pre-0.6 trees) surviving in the live vault with only seed READMEs; the
permissive leaf-readme route matches before the retired-path check, so
/echo-health never flags them.

- docs/history/echo-improvements-prompt.md (ROADMAP-2.0 §5 box ticked)
- README repository layout brought to 1.5.1 reality: root docs
(CHANGELOG/TODO-1.6/ROADMAP-2.0/docs/history), build.py + dist/
(gitignored, secret-bearing), current eval harness contents, hooks/,
and the full scripts/ roster (recall/reflect/triage/queue/
concurrency/quality/output/doctor/hook modules) with the legacy
commands/ dir annotated as the TODO-1.6 migration target. Also
restores the eval-descriptor fix lost in the prior commit (edit was
applied in memory but never written back).
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
- TODO-1.6.md: skills-format migration of the eight slash commands
(allowed-tools, disable-model-invocation, de-duped $ECHO block),
plugin.json homepage, vault link repoints, and an open section for
findings from 1.5.x live testing.
- ROADMAP-2.0.md: packaging & structure major — repo artifact policy
(Gitea releases, prune versioned zips), delete legacy commands/ dir,
codex-as-build-target if ever needed, eval refresh to current
metrics. Includes a disposition table absorbing every open
MAINTENANCE.md item, so that checklist is removed.
- Delete "codex plugin/": drifted derived tree; operator decision to
regenerate from the canonical source after 2.0 if Codex use returns.

Live 1.5.0 use caught the gate blocking a decision note over the single
vault-common token "echo" (min-normalized overlap gives any one-token
entity a 1.0 score). New echo_index.gate_candidates() + token_df():
- gate blocks same-kind candidates only; cross-kind name collisions
(a decision titled after its project) warn instead of blocking
- a lone shared token blocks only when unique to that entity (df == 1);
multi-token overlaps still block
fuzzy_candidates (advisory warnings) and exit-76/--merge-into/--force
semantics unchanged. +3 offline unit tests, gate e2e cases restructured
+2 new; verified live both directions. All suites green.
