ver 1.5.0 — six-improvement pass: retention, routing, self-firing memory

1. capture-update keeps the whole body (was truncating to first line)
2. frontmatter completeness: kind-default status + kind-seeded tags at
   capture, fm create-or-replace, incomplete-frontmatter lint, sweep
   backfill (one data source: KIND_STATUS/KIND_REQUIRED_FM)
3. pre-write duplicate gate (exit 76, --merge-into/--force)
4. recall corpus + ranking: sessions/journal indexed (down-weighted),
   BM25 x freshness x status fusion, recall --json, index schema 2
5. session hooks: SessionStart auto-load, Stop reflection nudge
6. one-tap triage verb with processing-log audit; --json on read verbs

+22 mock end-to-end tests; all suites green. Docs current (README,
CHANGELOG, SKILL.md, commands, references, MAINTENANCE, eval README).
Drops tracked .DS_Store (gitignored); retires README-gretchen.md
(moved to gitignored dist/); adds the field report that drove item 2.

 # Changelog
 
+## 1.5.0
+
+Six improvements from the July 2026 review + the frontmatter-drift field report.
+
+### Fixed — capture-on-update kept only the first body line (silent data loss)
+
+`capture` on an existing entity appended `- <date>: <first line>` and **discarded the
+rest of the body**. It now appends the whole body as a dated block — first line on the
+bullet, continuation lines indented under it. Idempotency (bullet-per-day) unchanged.
+
+### Added — frontmatter completeness (prevent → tool → detect → remediate)
+
+A field audit found 18/71 entity notes missing `status`/`tags`; the drift was created
+at write time and invisible to the tooling. Four coordinated changes, driven by one
+data source (`KIND_STATUS` / `KIND_REQUIRED_FM` in `echo_index.py`):
+
+- **`capture`** stamps a kind-appropriate default `status` (all kinds, not just
+  projects) and seeds `tags` with the note's kind; new `--tags a,b` enriches it.
+  Reflect/triage proposals accept a `"tags"` field.
+- **`echo.py fm`** is now **create-or-replace**: on `400 invalid-target` (missing key)
+  it surgically inserts the one line into the frontmatter block and re-PUTs, verified —
+  it previously failed on exactly the notes that needed repair.
+- **`vault_lint.py`** gains a kind-scoped `incomplete-frontmatter` check
+  (missing/empty `status`/`tags` on entity notes; block-style lists handled).
+- **`sweep.py --apply`** backfills flagged notes (kind-default status + baseline tag).
+
+### Added — pre-write duplicate gate in capture
+
+A strong fuzzy candidate (score ≥ 0.6, env `ECHO_DUP_GATE`) now **stops** `capture`
+before it creates a near-duplicate (exit `76` + candidate list) instead of warning
+after the file exists. `--merge-into <slug>` routes the capture as an update to the
+existing entity (mention learned as an alias); `--force` creates anyway. Weak
+resemblances still create + warn as before.
+
+### Changed — recall corpus + ranking (recall-index schema 2)
+
+- The BM25 corpus now includes **session logs and journal notes** (down-weighted 0.5 /
+  0.4 so entity notes win ties) — past discussions are findable without having been
+  promoted into an entity note. `echo.py put` keeps the index current for corpus paths.
+- Ranking fuses BM25 with **freshness** (half-life decay on `updated:`, floored at 0.6,
+  env `ECHO_FRESH_HALF_LIFE`) and **status** (`active` ×1.1, `on-hold` ×0.9,
+  `archived` ×0.75) — a stale archived note no longer outranks the live one.
+- Hits print `updated:`/`status:`; `recall --json` emits structured results.
+- The recall index carries per-doc meta (schema 2); an old index is discarded and
+  rebuilt automatically on the next recall/sweep.
+
+### Added — session hooks (self-firing load & reflect)
+
+New `hooks/hooks.json` + two hook scripts. **SessionStart** runs `echo.py load` and
+injects the output as context (skips resume/compact; NOT-CONFIGURED degrades to an
+instruction, never an error). **Stop** nudges once per substantive session (≥5 user
+turns, env `ECHO_REFLECT_MIN_TURNS`) when nothing was reflected or session-logged —
+reflection itself still previews and asks before writing. Both use the 1.4.2 CoWork
+path fallback and always exit 0.
+
+### Added — one-tap inbox triage + `--json` on read verbs
+
+New `echo.py triage`: `--list --json` parses the inbox into `{line, date, text,
+age_days}`; a proposals file (reflect schema + `"line"`) is classified → previewed →
+applied via `capture`, with the `inbox/processing-log/` audit line written per move
+(originals never deleted). `/echo-triage` rewritten around it. Also: `--json` for
+`recall`, `link`, and `scope show` (`resolve`/`capture` already had it).
+
+Tests: +22 feature cases (mock end-to-end incl. hooks), patch-semantics updated for
+the new `fm` contract; all suites green. Docs: SKILL.md, README, command docs updated.
