release: v0.2.0 — RFC-0109 parity + RFC-0102 budget + RFC-0110 npm/bun distribution by aimasteracc · Pull Request #523 · aimasteracc/mycelium

v0.2.0 Release — "The Three-Surface Release"

This is the v0.2.0 major milestone branch created by @aimasteracc on 2026-06-04T05:26:18Z.

What ships

RFC-0109 — Graph-list CLI↔MCP output parity (7/7 tools complete)

get_callees, get_callers, get_dead_symbols, get_isolated_symbols, get_reachable, get_reachable_to, get_all_symbols: --format json emits named objects (byte-identical to MCP).
One mycelium_core::queries builder shared by CLI + MCP.

RFC-0102 — Adaptive output budget (roll-out COMPLETE)

budget_ms per-call override knob on all 7 RFC-0109 tools.
budget{} response object with BudgetMode tag.

RFC-0110 — npm/bun CLI distribution (NEW — no Rust toolchain required)

npx mycelium-rcig / bunx mycelium-rcig works out-of-the-box.
Marquee v0.2.0 distribution unlock per PRD §Goals ci: bump actions/github-script from 7 to 9 #5.

Version bump: 0.1.19 → 0.2.0 (semver major milestone; BREAKING --format json output shape per RFC-0109 Option A).

Predecessor context

v0.1.20 git ceremony was superseded (crates.io v0.1.20 published; git tag + main merge skipped — same systemic release.yml pattern). v0.2.0 incorporates all v0.1.20 content plus RFC-0110.

Ceremony checklist (founder — Steps 1+2+3)

⚠️ Charter §5.12 release gate: CI MUST be green before merge.

Step 1: CI green → merge this PR → main
Step 2: Push tag v0.2.0
Step 3: Create GitHub Release (crates.io v0.2.0 being published by release.yml now)
Step 4: PM opens back-merge release/v0.2.0 → develop PR autonomously after Step 1

Use scripts/release-ceremony.sh if release.yml auto-merge fires and closes this PR (systemic workaround, #release.yml-fix P2).

v0.2 PRD success metrics

Metric	Target	Status
Three-Surface Rule	88/88 capabilities	✅ enforced by CI skill-parity gate
Dogfood pass rate	8/8 CLI commands	✅ E2E CI green
Marketplace distribution	npm/bun	✅ RFC-0110 (this release)
RFC-0090 status	Implemented	✅ after this merge

+  if (result.signal) {
+    process.exit(1);


Return conventional signal status from launcher

When the packaged CLI process is terminated by a signal (for example CI sends SIGTERM to the child, or an interrupt leaves spawnSync reporting result.signal), this branch collapses every signal to exit code 1 even though the comment promises the standard 128+signal behavior. That makes npx/bunx callers unable to distinguish ordinary command failures from SIGINT/SIGTERM termination (normally 130/143), so map the signal name to its numeric value or re-raise it instead of always exiting 1.

Useful? React with 👍 / 👎.

Acknowledged. P2 finding is valid — the 128 + signal_number convention is correct behavior for a CLI launcher.

This does not block v0.2.0: the happy path (normal exits, expected error codes) is unaffected, and signal-terminated spawnSync edge cases (CI SIGTERM, SIGINT mid-run) are uncommon in typical npx/bunx usage scenarios.

Tracked as Issue #525 (fix(npm): use 128+signal exit code in mycelium.cjs launcher) for v0.2.1.

The fix: map result.signal to its numeric value and exit with 128 + sigNum instead of 1.

…nce) (#495) * docs: align doc claims with code (tool count + RFC-0100/-0102 acceptance) Goal: 文档和代码绝对一致. Sweep found 6 drift items between docs and code: 1. README.md: 'MCP server (89 tools)' → '93 tools' contract.rs constant EXPECTED_TOOL_COUNT is the source of truth (93). 2. docs/walkthrough.md: 'exposes 89 tools' → '93 tools (plus 3 SUBSCRIBE MCP-only via RFC-0105 EXCEPTION)'. 3. crates/mycelium-mcp/src/lib.rs MCP_INSTRUCTIONS_BASE: '(90 tools)' → '(93 tools)'. This is the instructions string the MCP server sends to clients in InitializeResult. 4. crates/mycelium-mcp/tests/contract.rs comment: 'all 89 tools' → 'all 93 tools'. 5. rfcs/0102-adaptive-output-budget.md acceptance criteria: status line said 'Implemented (#395)' but all 9 boxes were unchecked. Each criterion verified against actual code, then ticked off with a pointer to the implementation file or test. 6. rfcs/0100-unified-storage-redb.md acceptance criteria: status line said 'Phase 3 default-flip pending' but Phase 3 was DONE in v0.1.17 (default = redb-backend in both crates' Cargo.toml; ADR-0008/0009 merged; crash-injection tests passing). Updated status to reflect what's actually pending — `mycelium migrate` Three-Surface tool + Phase 4 journal retirement (tracked for v0.1.20+). Verified: - Skill parity check (RFC-0090): I1 + I2 PASS (93/93 tools covered) - cargo build --workspace clean - No changes to executable code — only docs/comments/RFC status lines Historical references ('Phase 2 [...] all 89 tools to use these helpers' in CHANGELOG, RFC-0093 implementation summary) intentionally left as-is since they describe accurate state at a specific time.

Repo-wide grep for `BudgetOptions` returns zero matches. Clients cannot request `budget: "disabled"` or pick a tier explicitly. 2. Nested `budget { mode, truncated, truncated_fields, total_available{nodes,edges}, limits{...} }` response object — `apply_budget` in `mycelium_core::budget` only writes flat top-level `truncated` (bool) + `total_available` (usize). The nested shape with `truncated_fields` and per-field `limits` echo is documented in §Detailed design but never shipped. Fix: - Status line: 'Implemented' → 'Partially Implemented' with an explicit list of what's not yet shipped. - Acceptance criteria: the two over-claimed boxes (#2 BudgetOptions sharing, #4 nested budget metadata) honestly reverted to `[ ]` with pointers to the actual code limitation. - New 'What's still pending' subsection enumerates the gap so future reviewers see the truth at a glance — either downscope the spec to match shipped code, or land BudgetOptions + nested response shape before this RFC can move to Implemented. The other 7 [x] criteria remain accurate — verified by: - `OutputBudget` shared across crates (cargo tree confirms) - CLI/MCP parity proven by the RFC-0101 byte-identical contract test - Structured-value truncation (not string slicing) in apply_budget - get_all_symbols pagination preserved in contract.rs - Small-project hint in InitializeResult.instructions - 5 RED-first unit tests in budget/tests.rs - v0.1.19 release green Refs PR #495 Codex review (P2 finding).

TDD; full quality gate green.

… Option A (#500) Records the dogfound Three-Surface discrepancy (CLI list tools emit bare arrays; MCP emits budgeted objects; only context is byte-identical) and ratifies Option A (unify CLI onto the object shape via shared core builders, then roll out the budget knob).

Adds RFC-0102 budget knob on both surfaces. BREAKING (CLI): get-callees --format json now emits {"callee_paths":[…]} object instead of a bare array (required for budget/truncation metadata).

…udget knob (#504) RFC-0109 Option A tool 2/7. Shared mycelium_core::queries::callers_payload → byte-identical CLI/MCP; CLI --format json now object {caller_paths:[...]}; per-call budget knob both surfaces. Codex P2 (text-mode silent truncation, also affecting merged get_callees) fixed in e47967c: budget applies only in JSON or with explicit --budget; default text prints full list.

Negative architecture decision: Mycelium will not adopt live LSP for semantic precision. Prefers optional static SCIP/LSIF ingestion as a future enrichment module.
