chore(release): v0.9.27

[rohitg00]

Wave release bundling two real-world bug fixes + the benchmark scorecard correction. Drop-in upgrade; no breaking changes.

What ships

• Bug: /graph/query and /graph/stats still return "Invocation stopped" on v0.9.26 at large corpus, even with limit=10 (related to #753 / #309) #814 / fix(graph): top-degree snapshot cache for /graph/query + /graph/stats (#814) #816 — /graph/query + /graph/stats no longer time out on large corpora. Refactored mem::graph-extract to maintain incremental side-indexes (graphNameIndex / graphEdgeKey / graphNodeDegree) so writes are O(1). Hot path reads exclusively from a top-degree snapshot updated inline on every extract. New POST /graph/snapshot-rebuild (safe ≤ 25K nodes) and POST /graph/reset (clean-restart escape hatch) endpoints. Same kv.list bottleneck was also slowing every observation capture, so the fix accelerates the observe pipeline too.
• [bug]I'm not sure if this is a bug. When deploying multiple agents locally, it's impossible to assign separate specific ports to each of them. #750 / fix(cli): auto-derive streams + engine ports from REST anchor (#750) #815 — --port N now drags streams (N+1) and iii engine (N+46023) along. New --instance N shortcut picks a 100-port block off the 3111 base for multi-daemon deployments.
• Coding Agent Life v1 reproduce problem #796 / docs(benchmarks): correct coding-agent-life-v1 P@5 numbers (#796) #805 — corrected coding-agent-life-v1 scorecard P@5 numbers (original 0.578 / 0.267 were mathematically impossible under the current hits / k formula; re-scored on v0.9.26 to 0.240 / 0.227).
• docs(readme): refresh stats + v0.9.26 callout + corrected P@5 #807 — README refresh to v0.9.26 callout, refreshed stats (174 files / 1,390+ tests / 258 functions), corrected hero P@5 numbers, bumped stat-tests badge.

Version bumps

• package.json, plugin/plugin.json, plugin/.claude-plugin/plugin.json, plugin/.codex-plugin/plugin.json, packages/mcp/package.json — 0.9.26 → 0.9.27
• src/version.ts — VERSION literal
• src/types.ts — ExportData.version union
• src/functions/export-import.ts — supportedVersions Set
• test/export-import.test.ts — assertion

Test plan

• npm run build clean
• npx vitest run — 1417/1417 pass (12 new graph tests + 7 multi-instance port tests)
• Tag + publish on merge

Walkthrough

This PR is a version release for v0.9.27. It updates release notes documenting bug fixes and new features, bumps the version constant and all package/plugin manifests from 0.9.26 to 0.9.27, and extends export schema compatibility to support the new version.

Changes

Version 0.9.27 Release

Layer / File(s)	Summary
Release notes documentation CHANGELOG.md	CHANGELOG adds v0.9.27 entry documenting performance/timeout fixes for graph endpoints on large corpora, multi-instance port collision resolution via stream/engine port offsetting and --instance flag, docs corrections for scorecard P@5 and README refresh, new graph snapshot endpoints and fields, and snapshot-first behavior for graph statistics and query operations.
Version constant and manifest updates src/version.ts, package.json, packages/mcp/package.json, plugin/plugin.json, plugin/.claude-plugin/plugin.json, plugin/.codex-plugin/plugin.json	Core VERSION constant and all package/plugin manifests are bumped from 0.9.26 to 0.9.27 consistently across the monorepo.
Export schema version compatibility src/types.ts, src/functions/export-import.ts, test/export-import.test.ts	ExportData.version union in types and supportedVersions allowlist in mem::import are extended to accept 0.9.27 exports; test expectation is updated to match.

Poem

🐰 A whisker-twitch release, so fine,
From 0.9.26 to 0.9.27 in time,
Graph snapshots bloom, versions aligned,
Manifests and types, harmoniously signed.
Export schemas welcome the new,
Ready and stable, through and through! 🌟
