## [Unreleased]
+### Added — v2.1 "Reliability + Zero-Friction Install" track
+
+- **`engram update`** — one-command self-upgrade.
+ Passive notify on every `engram *` invocation when a newer version is
+ available (cached, at most one line on stderr, throttled to a 7-day
+ registry check). Manual trigger detects the package manager that owns
+ the engram install (npm / pnpm / yarn / bun via install-path markers)
+ and shells out to its global-upgrade command. `--check` for dry-probe,
+ `--force` to bypass the 7-day throttle, `--dry-run` to print the
+ upgrade command without executing it, `--manager ` override.
+ Zero telemetry: the only network call is an anonymous GET to
+ `registry.npmjs.org/engramx/latest`. `ENGRAM_NO_UPDATE_CHECK=1` and
+ `$CI` disable the entire subsystem. Addresses the "1,300 weekly
+ downloads, 10/day organic, near-zero hotfix reach" problem.
+
+- **`engram doctor`** — component health report with remediation hints.
+ Wraps existing probes (HTTP, LSP, AST, IDE adapters) plus four new
+ checks: engram version freshness, `.engram/graph.db` presence,
+ Sentinel hook installation, IDE adapter count. Each check emits
+ severity (ok / warn / fail) + detail + optional remediation. Exit
+ code reflects overall severity (0 ok, 1 warn, 2 fail) so `doctor`
+ is CI-friendly. `--verbose` shows remediation hints; `--json` /
+ `--export` emits redacted JSON for bug-report attachment
+ (`projectRoot` intentionally omitted — can contain usernames).
+
+- **`engram setup`** — zero-friction first-run wizard. One command for
+ "go from cloned repo to working engram in under 30 seconds."
+ Runs `init` (if `.engram/graph.db` missing) → `install-hook` (with
+ prompted scope, `local` default) → detects IDE adapters (Cursor,
+ Windsurf, Continue.dev, Aider) and suggests the matching `gen-*`
+ command for each → finishes with a `doctor` summary. Each step is
+ idempotent. `--yes` runs with defaults; `--dry-run` prints intent
+ without acting; `--scope` controls the install-hook scope. Drops
+ install-to-first-value from 4 commands to 1.
+
+- **`engram init --with-hook`** — shorthand for `init` followed by
+ `install-hook` (local scope, idempotent). The #1 thing every user
+ does after `init` was `install-hook`; now it's one step.
+
+- **First-run hint.** On any `engram` subcommand invoked in a repo
+ lacking `.engram/graph.db`, print one line on stderr:
+ `💡 First time in this repo? Run 'engram setup' for a zero-friction install.`
+ Throttled via `~/.engram/first-run-shown` (fires once per machine,
+ not per repo). Silenced in `$CI`, under `ENGRAM_NO_UPDATE_CHECK=1`,
+ and under the JSON-stdout commands (`intercept`, `cursor-intercept`,
+ `hud-label`, `setup`, `init`, `update`, `doctor`) so neither
+ pollutes the hook protocol.
+
+- **Bash PostToolUse parser for auto-reindex** — closes half of
+ [#14](https://github.com/NickCirv/engram/issues/14).
+ `src/intercept/handlers/bash-postool.ts` parses file-mutating Bash
+ commands (`rm`, `mv`, `cp`, `git rm`, `git mv`, single-redirect
+ ` > `) into `FileOp { action, path }` records. Strict
+ parser: globs, pipes, subshells, command-substitution, directory
+ ops, and `touch` all pass through untouched. Wired into the
+ PostToolUse observer path in `handlers/post-tool.ts` — on Bash
+ PostToolUse events, each op is handed to `syncFile()` fire-and-forget.
+ Gated by `ENGRAM_AUTO_REINDEX=1` opt-in until
+ [#13](https://github.com/NickCirv/engram/pull/13)'s install-hook
+ `--auto-reindex` flag lands; that flag will toggle the env gate
+ implicitly.
+
+### Fixed — v2.1 reliability
+
+- **AST grammar detection in flattened bundles**
+ ([#11](https://github.com/NickCirv/engram/issues/11) partial).
+ When `tsup`/`esbuild` flattens chunks to `engramx/dist/chunk-*.js`,
+ `import.meta.url` resolves to `engramx/dist` and the previous
+ candidates (`../grammars` and `../../dist/grammars`) both missed the
+ actual grammar dir. Added `join(here, "grammars")` as the first
+ candidate; dev-time layout (`src/intercept/`) still works via the
+ third candidate. Thanks [@ttessarolo](https://github.com/ttessarolo).
+
+- **LSP socket candidate coverage**
+ ([#11](https://github.com/NickCirv/engram/issues/11) partial).
+ `checkLsp` was looking for two socket names while
+ `lsp-connection.ts::candidateSockets()` probes six. Synced the list
+ so HUD availability matches actual provider availability. Kept
+ `.engram/lsp-available` as an explicit user opt-in marker for
+ back-compat.
+
### Fixed
- **Locale-independent number formatting across the codebase.** All 10

+# engram Elevation Trilogy — Design Spec
+

+> **Supersedes:** `00-strategy/next-steps-roadmap.md` v2.0 tail.
+
+## TL;DR
+
+Three sequential releases, each standalone-useful, each setting up the next.
+
+| Release | Codename | Ship target | Theme |
+|---------|----------|-------------|-------|
+| **v2.1** | Reliability + Zero-Friction Install | +1 week | Close the bleeding — merge contributor PRs, fix #11, seamless install |
+| **v2.2** | Spine | +2 weeks | Serena as a first-class engram provider via reusable MCP-client subsystem |
+| **v3.0** | Landmines | +3-4 weeks | Mistakes-as-moat expansion + R2 reposition ("the context tool that remembers what broke") |
+
+Between v2.0.2 (shipped 2026-04-18) and v3.0, engram transitions from *"another memory tool"* (ratioed in r/LocalLLaMA) to *"the context tool that remembers what broke"* — differentiated, authoritative, orchestrating Serena, not fighting it.
+
+## Research grounding (2026-04-20)
+
+- **GitHub issues = table stakes:** #5 OOM, #6 contributor OOM fix PR, #11 AST/LSP silent unavailability, #13 reindex CLI PR, #14 Bash auto-reindex. Two external contributors (@gabiudrescu +) actively submitting substantive PRs.
+- **npm downloads:** 1,300/week; 10/day organic baseline spiking to 450+ on launch days. Retention unknown — hotfixes don't reach 90% of installs because no self-update path.
+- **Reddit reality:** r/LocalLLaMA post ratioed (0.44, "why do I see one of these daily"). 4+ projects named "Engram/Claude Engram/Engram Memory" launched Mar-Apr 2026. **Name collision is real; rename is prohibitively expensive.**
+- **Competitors:** Serena just hit stable (JetBrains-powered LSP + published evals), Vera (Rust semantic search), Anthropic native Auto-Memory + Auto-Dream. Engram's differentiator is *not* semantic retrieval (losing ground) — it's the `mistakes` provider + graph orchestration.
+
+## Strategic choices (recorded)
+
+- **Thesis:** T1 + T2 + T3 — all three shipped sequentially as a trilogy (option α over mega-release β or two-way split γ).
+- **Positioning:** R2 (keep the name `engram`/`engramx`, rebrand tagline). Rename (R3) is rejected — 2-week migration cost for marginal discovery gain; npm dist-tag equity + GitHub history + active contributors outweigh.
+- **Update UX:** Option A — passive notify + manual `engram update`. No background auto-install. Privacy-preserving (no telemetry). Kill-switch via env.

+
+# v2.1 — "Reliability + Zero-Friction Install"
+
+## Scope
+
+### Track A — Close the bleeding (reliability)
+
+| Issue | Action | Owner |
+|-------|--------|-------|
+| **#5 + #6** init OOM on large repos | Merge @gabiudrescu's PR #6 (MAX_DEPTH=100, MAX_FILES_PER_COMMIT=50, `.engramignore`, expanded exclusions). Regression test on 50K-file fixture. | Merge + verify |
+| **#11** AST/LSP unavailable despite enabled | Forensic debug `src/providers/resolver.ts:_resetAvailabilityCache`, `src/providers/ast.ts:isAvailable`, `src/providers/lsp.ts:getConnection`. Add regression test that forces enabled=true + asserts provider actually emits rows. | Dedicated follow-up — NOT in the same commit as seamless-install work. |
+| **#13** `engram reindex ` CLI | Merge existing PR. Add `--auto-reindex` flag to `install-hook`. | Merge |
+| **#14** Bash auto-reindex | Widen `--auto-reindex` PostToolUse matcher to Bash. Parse `rm`/`mv`/`cp`/`git rm`/`git mv`/`>`/`>>`. Silent-skip on non-code paths. Reuse `syncFile` primitive. | New code: `src/intercept/handlers/bash-postool.ts` + tests |
+| **#3** ecosystem miners | **Defer to v2.2.** Tag the PR "v2.2 candidate." | — |
+
+### Track B — Zero-friction install
+
+| Command | Description |
+|---------|-------------|
+| **`engram update`** | Detect install manager (npm/pnpm/yarn/bun). Shell out to upgrade command. Verify `engram --version` changed. `--check` dry-run (no install). Passive notify: on any `engram *` invocation, if `~/.engram/last-update-check` > 7 days old and newer version exists, print one-line hint. `ENGRAM_NO_UPDATE_CHECK=1` and `$CI` disable. No telemetry beyond one anonymous GET to `registry.npmjs.org`. |
+| **`engram doctor`** | Wrap `src/intercept/component-status.ts` probes into human report. Per-component: ✓/⚠/✗ + remediation hint. `--verbose` for detail. `--json` for machine. Non-zero exit on critical failure. |
+| **`engram setup`** | First-run wizard. Steps: (1) `engram init` in current repo if not initialized; (2) `engram install-hook` with scope prompt; (3) detect Cursor/Windsurf/Continue configs and offer adapter setup; (4) run `engram doctor` to verify. One command for "done, working." |
+| **`engram init --with-hook`** | Shorthand: init + install-hook in one invocation. Safe-additive to existing `init`. |
+| **First-run hint** | On any `engram` subcommand run in a repo lacking `.engram/graph.db`: print `💡 First time? Run 'engram setup' for a zero-friction install.` Throttle via `~/.engram/first-run-shown`. Skip in CI. |
+
+### Track C — Diagnostics (local-only, no telemetry)
+
+| Feature | Description |
+|---------|-------------|
+| **Crash reports** | On `init` / `watch` / `server` throw: write `~/.engram/crashes/.log` with stack + node version + repo size + engram version. Print path to user. |
+| **`engram doctor --export`** | Redacted JSON blob — versions + OS + component statuses. User copy-pastes into bug reports. |

+
+# v2.2 — "Spine" (Serena provider)
+
+## Strategic framing
+
+> *"engram is the spine; Serena is the LSP. You install one tool, get both."*
+
+Engram orchestrates; Serena does what Serena does best (LSP-grade references). This validates engram's "context spine" positioning at the architecture level. Any future MCP tool (Cursor memory, sequential-thinking, new LSP bridges) plugs in through the same subsystem.
+
+## Architecture
+
+```
+src/
+ mcp-client/ ← NEW — reusable subsystem
+ client.ts ← stdio JSON-RPC client
+ lifecycle.ts ← spawn / warm / healthcheck / shutdown
+ budget.ts ← per-provider token budget allocator
+ providers/
+ serena.ts ← NEW provider
+ serena-tool-map.ts ← query-intent → Serena tool routing
+ intercept/
+ component-status.ts ← add checkSerena()
+bench/
+ tasks/semantic/ ← NEW — 5 benchmark tasks
+ task-11-find-caller-lsp
+ task-12-cross-module-reference
+ task-13-polymorphic-dispatch
+ task-14-inherited-method
+ task-15-indirect-caller
+```
+
+## Serena tools exposed (5 only)
+
+| Serena tool | Engram provider emits | Rationale |
+|-------------|----------------------|-----------|
+| `find_symbol` | symbol location + precise signature | Graph file-for-class, LSP-precise |
+| `find_references` | 2-hop reverse graph | LSP-exact find-caller replaces regex |
+| `get_symbol_body` | 50-line function body | Read function without full-file read |
+| `list_symbols_overview` | architecture sketch | Improves task-07 benchmark |
+| `get_symbols_overview` | per-file symbol summary | On-demand hot-file exploration |
+
+**Deliberately skipped:** all `replace_*`/`insert_*` write tools. Engram reads through Serena, writes nothing. Keeps security posture simple.
+
+## Budget allocator
+
+```
+intent = "find-caller" → serena 60%, structure 20%, git 10%, mistakes 10%
+intent = "how hot is X" → git 60%, structure 20%, mistakes 20%
+intent = "landmine check" → mistakes 50%, git 30%, structure 20%
+intent = "unknown" → even split across top 5
+```
+
+Provider weights are data-driven via `config.ts`. Minimum floor per enabled provider: 5% of packet (prevents starvation). Learnable later in v3.0.
+
+## Graceful degradation matrix
+
+| State | Behavior |
+|-------|----------|
+| Serena not installed | `doctor` shows: `⚠ Serena: not installed. Install: pip install serena-agent`. Engram falls back to AST provider. |
+| Serena wrong version | Compat matrix in availability check. Fall back. |
+| Serena crashes mid-session | MCP client restarts once; on 2nd crash, disable for session. |
+| Serena slow (>2s) | Per-query timeout; return partial. |
+| User opts out | `ENGRAM_DISABLE_SERENA=1` or `engram config set serena.enabled false`. |
+
+## Acceptance criteria
+
+- [ ] 5 new bench tasks with **real measured numbers** (no estimates in the launch post)
+- [ ] `engram doctor` reports Serena status + install hint
+- [ ] 30+ new mcp-client tests (lifecycle, timeouts, reconnect, corruption)
+- [ ] Graceful fallback verified — kill Serena mid-session, engram keeps working
+- [ ] Budget allocator: 10+ adversarial queries stay ≤500 token packet
+- [ ] `engram setup` v2.1 wizard detects missing Serena and offers `pip install serena-agent`
+- [ ] Licensing: Serena MIT + engram Apache-2.0 — no embedding, stdio-only, zero contamination
+
+## Risks
+
+| Risk | Mitigation |
+|------|-----------|
+| Serena spawn cold-start 1-2s | Warm on SessionStart, subsequent queries cached |
+| Python dep breaks engram's "zero native deps" brand | Serena is **optional**; engram core stays zero-deps. Precise language in README. |
+| Serena API churns | Pin compat range in availability check; `doctor` catches mismatch |
+| Budget allocator starves non-Serena providers | 5% floor per enabled provider, adversarial-query tests |
+
+---
+
+# v3.0 — "Landmines" (Mistakes moat + R2 reposition)
+
+## Strategic framing
+
+> *"engram is the only context tool that remembers what broke."*
+
+The `mistakes` provider is already unique. v3.0 doubles down:
+- **Live regret learning:** `engram learn "X was wrong because Y"` post-compaction auto-surfaces in the NEXT session
+- **Confidence decay:** mistakes fade over time unless re-confirmed (prevents stale-warning fatigue)
+- **Agent-visible scoring:** the context packet shows *why* a file is landmined — "3 mistakes in last 30d, newest from 2d ago"
+- **Budget-allocator integration:** landmined files get automatic priority boost in provider weighting
+- **Cross-session replay:** after context compaction, mistakes for files touched in recent session get re-injected first
+
+## R2 repositioning
+
+- **Homepage tagline change:** from "The context spine for AI coding agents" → "The context tool that remembers what broke."
+- **Reddit narrative:** lead every post with a mistake-story ("Claude spent 2 hours rewriting the auth flow in the exact way we learned NOT to last month. engram stops that.")
+- **README hero section:** restructure around landmines as the lead value-prop; graph/Serena/cache become supporting evidence.
+- **No rename** — npm, GitHub, URLs stay. Tagline rebrand only.
+
+## Scope (initial — to be refined in a v3.0 design spec)
+
+- Expand `mistakes-miner` to catch more failure patterns (deprecation warnings, test failures, agent self-corrections)
+- Add `engram landmines` CLI (`mistakes` alias + decay + density ranking)
+- Budget-allocator scoring boost for files with recent mistakes
+- Cross-session mistake-replay after PreCompact
+- Ship 5 new bench tasks that explicitly measure "mistake avoidance"
+- Reposition all marketing copy on cirvgreen.com/products/engram
+
+## Acceptance criteria (placeholder — v3.0 spec to be written after v2.2 ships)
+
+- [ ] Mistakes density visible in `engram stats` and dashboard
+- [ ] Confidence decay tested on synthetic 90-day timeline
+- [ ] "Landmine avoidance" bench tasks — measurable % improvement
+- [ ] cirvgreen.com/products/engram rewritten around new tagline
+- [ ] Reddit launch: r/LocalLLaMA (the one we ratioed) + r/ClaudeCode + r/mcp + HN
+
+---
+
+# Release rhythm
+
+```
+Week 1 → v2.1 ships (Reliability + Zero-Friction Install)
+Week 1-3 → v2.2 designed + built (Spine / Serena)
+Week 3 → v2.2 ships
+Week 3-7 → v3.0 designed + built (Landmines / R2)
+Week 7 → v3.0 ships — the authoritative reposition moment
+```
+
+Three launches in ~7 weeks. Each standalone-useful. Each building credibility for the next.
+
+## Success metrics (per release)
+
+| Metric | v2.1 | v2.2 | v3.0 |
+|--------|------|------|------|
+| npm weekly downloads (target) | 1.8K (+40%) | 3K | 6K |
+| GitHub stars (target) | +50 | +100 | +300 |
+| Reddit post score | ≥50 on r/ClaudeCode | ≥100 on r/LocalLLaMA | ≥300 on r/LocalLLaMA |
+| Retention proxy (downloads 7d after non-launch day) | 15/day | 25/day | 60/day |
+| Active contributors | 2 → 3 | 3 → 4 | 4 → 6 |
+
+---
+
+# Non-goals (entire trilogy)
+
+- **No team/shared-graph feature.** Single-user remains the scope.
+- **No cloud backend.** Local-first is invariant.
+- **No embedding layer inside engram core.** Hybrid retrieval is a Serena-style-provider concern.
+- **No rename or npm repackaging.**
+- **No paid tier.** engram remains 100% Apache-2.0 through v3.0. Monetization, if ever, comes *after* distribution is proven.
+- **No backwards-incompat breakage.** v1.x graph.db auto-migrates all the way through v3.0.
