Subject: [PATCH 05/55] fix(opencode): install to ~/.config/opencode instead of
 ~/.opencode

OpenCode natively uses ~/.config/opencode per XDG conventions. The
install target was writing to ~/.opencode, which only worked on systems
where that path happened to be symlinked to ~/.config/opencode. The MCP
inventory reader already looked in ~/.config/opencode, so the installer
and reader were inconsistent.

Subject: [PATCH 08/55] fix(install): add skills/skill-comply to
 workflow-quality module
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

skill-comply was the last unreferenced skill directory — every other
curated skill is referenced by at least one module in
manifests/install-modules.json. Without this entry, --profile full
silently installs 284 of 285 skills and the gap is invisible from the
install output.

Added to the workflow-quality module alongside the other evaluation,
audit, and compliance skills (skill-scout, skill-stocktake,
production-audit, etc.).

Verified: dry-run --profile full --json now includes 22 skill-comply
files in the install plan, and a manifest-coverage scan reports zero
unreferenced skill directories.

Fixes #2789

Subject: [PATCH 09/55] fix(scripts): auto-detect legacy sync-ecc-to-codex.sh
 installs in uninstall

When no install-state is found for the current context, `ecc uninstall`
now checks for the legacy `sync-ecc-to-codex.sh` ownership manifest under
`~/.codex/ecc/legacy-sync-state.json` and, if present, rolls back the
managed Codex artifacts it recorded. It restores previous `config.toml`
and `AGENTS.md` content instead of deleting them, removes generated
prompts/docs/copies, and leaves unrelated Codex conversation history and
user config keys untouched. A fallback `--legacy-codex-sync` flag still
forces the legacy path explicitly, and `--dry-run` previews the cleanup.

Subject: [PATCH 10/55] fix(scripts): avoid false-positive legacy Codex sync
 detection

Tighten uninstall auto-detection so it only falls back to the legacy
sync-ecc-to-codex.sh path when there is an ownership manifest
(~/.codex/ecc/legacy-sync-state.json) or an ECC marker block in
~/.codex/AGENTS.md. Previously a clean Codex home with unrelated prompt
files could be misclassified as a legacy install, causing uninstall to
skip normal install-state reconciliation and exit with a partial warning.

Also make the no-state fallback return 'not-found' when there is no
marker to remove and no candidate files to clean, and make explicit
--legacy-codex-sync report the same on a clean home.

Subject: [PATCH 11/55] fix(scripts): require legacy ownership manifest for
 auto fallback

Restrict the automatic `uninstall` legacy Codex sync fallback to homes
that have a legacy ownership manifest (`~/.codex/ecc/legacy-sync-state.json`).
Marker-only AGENTS.md files are no longer auto-detected as legacy installs,
so a normal `uninstall` will not silently modify user-owned instructions.
The explicit `--legacy-codex-sync` flag still handles marker-only and
manifest-backed cleanup.

Also:
- Track the AGENTS.md path in removedPaths when a marker block is removed.
- Refactor codex home resolution into a helper.
- Add regression tests for marker-only auto vs. explicit behavior.

Subject: [PATCH 12/55] fix(scripts): surface unreadable AGENTS.md in legacy
 codex sync detection

hasMarkerBlock previously swallowed every read/open error and returned
false, so an unreadable AGENTS.md (EACCES, EMFILE, EISDIR, ...) made
detectLegacyCodexSync report a clean Codex home instead of an
indeterminate inspection result. The fallback path could then skip
legacy cleanup and exit 0 with legacy artifacts still in place.

Restrict the catch to ENOENT (a missing file legitimately means no
marker block) and rethrow everything else. detectLegacyCodexSync
already propagates from hasMarkerBlock, so callers now see the actual
inspection error instead of a misleading 'no marker'.

Regression test in tests/lib/codex-legacy-sync.test.js makes a
detectLegacyCodexSync call against an unreadable AGENTS.md and asserts
that it throws something other than ENOENT, plus a sanity check that
a missing AGENTS.md still reads as no-marker.

 ## Unreleased
 
+## 2.2.0 - 2026-08-25
+
+### Added
+
+- Guided, manifest-driven setup across supported harnesses, with exact install-state ownership, health checks, repair, and uninstall workflows.
+- Native Antigravity 2.0 installation under `.agents/`, including rules, workflows, skills, and adapted agents, plus a cross-platform installation guide.
+- New workflow and operator capabilities including the Itô skill family, Nasiko integration, multi-model council review, dev-team collaboration, agent evaluation, living-docs governance, secure terminal opening, and TasteForge multimodal workflows.
+- A thin Pi adapter and expanded cross-harness support, release artifact lifecycle testing, Docker-based CLI testing, and stronger Python validation.
+
 ### Changed
 
 - Default MCP connector set reduced to a single connector (`chrome-devtools`) per the new connector policy (`docs/MCP-CONNECTOR-POLICY.md`). The six previous defaults (`github`, `context7`, `exa`, `memory`, `playwright`, `sequential-thinking`) were retired after the June 2026 audit: their jobs are covered by skills wrapping CLIs/REST APIs (`github-ops`, `documentation-lookup`, `exa-search`, e2e skills) or by harness-native features (memory, extended thinking, web search). All six remain opt-in via `mcp-configs/mcp-servers.json`.
+- OpenCode home installs now use its canonical `~/.config/opencode` location, and bundled agents inherit the model selected by the user instead of pinning an Anthropic provider.
+- `skill-comply` is now part of the install manifest and npm distribution, with generated Python caches excluded from both install and package surfaces.
+- Release automation now verifies the tag is exactly on `origin/main`, fails closed on npm registry errors, tests the exact packed artifact across Linux, macOS, and Windows, publishes npm before creating the GitHub Release, and uses reviewed release notes.
 
 ### Fixed
 
 - `ecc memory` writes and `--body-file` reads failed on Windows under Node 22.12-22.16 and 24.0-24.1. libuv resolved path-based `stat()`/`lstat()` through `GetFileInformationByName` without setting the volume serial, while `fstat()` reported it, so the memory vault's TOCTOU guard rejected every operation. Fixed upstream in libuv 1.51.0; the guard no longer depends on the runtime's patch level. The guard's stat calls now request `BigInt` values, so Windows file IDs past `Number.MAX_SAFE_INTEGER` can no longer collapse two distinct files into one identity.
+- Selective reinstall now merges the prior ownership ledger, so later module additions do not orphan files from earlier installs and uninstall removes the complete managed surface.
+- Legacy Codex sync uninstall now uses ownership evidence, preserves user files, and requires an explicit opt-in for weaker marker-only cleanup.
+- Hook, plan-canvas, session, memory, observer, skill-evolution, Discord delivery, and Windows compatibility regressions fixed across the runtime.
+
+### Release audit
+
+- Audited the complete delta from `v2.1.0`: 108 commits across 530 files, with 40,299 insertions and 4,679 deletions on the pre-release baseline.
+- The release gate installs and exercises the exact npm archive, including cumulative ownership, doctor, drift detection, repair, uninstall, and user-file preservation.

+# ECC 2.2.0
+
+ECC 2.2.0 makes the universal installer a first-class, cross-harness distribution path. It adds native Antigravity 2.0 support, repairs cumulative install ownership, aligns OpenCode with its canonical configuration directory, and strengthens the exact-artifact release gate.
+
+## Installer and harness reliability
+
+- Antigravity installs natively to `.agents/{rules,workflows,skills,agents}`. Do not manually rename a legacy `.agent` directory. Re-run ECC 2.2.0 so the installer can apply its ownership-aware migration rules.
+- Repeated selective installs retain the complete managed ownership ledger. A later module install no longer causes previously installed ECC files to survive uninstall.
+- OpenCode home installs use `~/.config/opencode`, and its bundled agent definitions inherit the user's selected model provider.
+- Legacy Codex sync cleanup requires ownership evidence by default and preserves untracked or modified user files.
+- `skill-comply` is included in both the install graph and npm archive. Python bytecode and pytest caches remain excluded.
+
+## New capabilities
+
+- Guided multi-harness setup and stronger doctor, repair, status, and uninstall flows.
+- Native Antigravity 2.0 documentation for Bash and PowerShell.
+- Expanded Itô, Nasiko, agent-evaluation, multi-model council, dev-team, living-docs, secure terminal, Pi, and TasteForge workflows.
+- Improved Plan Canvas, memory vault, continuous learning, skill evolution, hook stability, session handling, and Discord delivery.
+
+## Release assurance
+
+- The release workflow requires the tagged commit to equal `origin/main` exactly.
+- npm registry failures stop the release instead of being treated as an unpublished version.
+- The exact packed archive is hashed once and exercised on Linux, macOS, and Windows before publication.
+- The verified npm archive is published before the matching GitHub Release is created. A retry verifies byte-for-byte registry integrity.
+
+## Upgrade
+
+Install or update the published package, then run the same ECC install command you used previously:
+
+```bash
+npm install -g ecc-universal@2.2.0
+ecc install --target antigravity --profile full
+```
+
+Use `ecc doctor --target <target>` after installation. For Antigravity, start a new conversation and verify workspace skills under Settings > Customizations.
+
+## Scope audited
+
+The pre-release audit covered the complete delta from `v2.1.0`: 108 commits, 530 changed files, 40,299 insertions, and 4,679 deletions before the final readiness patch.

+# ECC 2.2 release-readiness TDD evidence
+
+Date: 2026-08-24
+
+## Scope
+
+This pass covers the release blockers found in the delta from `v2.1.0`: cumulative selective-install ownership, native Antigravity packaging, canonical OpenCode installation, provider-neutral OpenCode agents, `skill-comply` distribution, conservative legacy Codex uninstall, release-workflow safety, and guided-install filesystem boundaries.
+
+## RED
+
+Commit `6e66dfba` added release regressions before the repairs. All six focused commands exited nonzero on the `origin/main` baseline:
+
+- A second selective install retained only the second module in install-state.
+- OpenCode resolved to `~/.opencode` instead of `~/.config/opencode`.
+- Managed preflight accepted a plan without an install-state path.
+- `skill-comply` was absent from the npm archive.
+- Release workflows lacked registry-error discrimination, an exact-main gate, reviewed notes, and npm-first publication ordering.
+- The packed lifecycle did not exercise Antigravity or OpenCode.
+
+Commit `528dbea0` added a security regression proving guided preflight accepted an identical copy source through a symbolic link. It failed before the no-follow snapshot repair.
+
+## GREEN
+
+- Focused installer, lifecycle, packaging, release-workflow, manifest, OpenCode, Antigravity, and uninstall tests passed.
+- Full repository suite: 3,958 passed, 0 failed.
+- `npm audit --audit-level=low`: 0 vulnerabilities.
+- Supply-chain IOC scan: 207 files inspected, no findings.
+- Both release workflow YAML files parsed successfully.
+- Exact packed archive lifecycle passed on macOS with Node 24.9.0 using SHA-256 `c79fbabbbb2567835081c17804f692c77b0673f22e0e0a2e63e870b99a7b8592`.
+- The packed lifecycle covered npm installation, public CLI setup, cumulative Cursor install, drift detection, repair, uninstall, user-file preservation, Antigravity install/doctor/uninstall, and OpenCode install/doctor/uninstall.
+
+## Focused coverage
+
+All three changed core modules exceeded the 80 percent line target:
+
+| Module | Lines | Functions | Branches |
+| --- | ---: | ---: | ---: |
+| `scripts/lib/multi-harness-setup.js` | 88.42% | 82.75% | 73.18% |
+| `scripts/lib/install/claude-skill-migration.js` | 95.20% | 100% | 88.78% |
+| `scripts/lib/install-targets/opencode-home.js` | 86.66% | 100% | 78.94% |
+
+Coverage commands used `c8 --check-coverage --lines 80` against the corresponding focused test files.
+
+## Release boundary
+
+No merge, release tag, GitHub Release, or npm publication was performed during this pass.

 ### Changed
 
 - Default MCP connector set reduced to a single connector (`chrome-devtools`) per the new connector policy (`docs/MCP-CONNECTOR-POLICY.md`). The six previous defaults (`github`, `context7`, `exa`, `memory`, `playwright`, `sequential-thinking`) were retired after the June 2026 audit: their jobs are covered by skills wrapping CLIs/REST APIs (`github-ops`, `documentation-lookup`, `exa-search`, e2e skills) or by harness-native features (memory, extended thinking, web search). All six remain opt-in via `mcp-configs/mcp-servers.json`.
-- OpenCode home installs now use its canonical `~/.config/opencode` location, and bundled agents inherit the model selected by the user instead of pinning an Anthropic provider.
+- OpenCode home installs now use its canonical `~/.config/opencode` location, safely discover and migrate unchanged ECC-managed files from legacy `~/.opencode` installs, and preserve modified legacy files for review. Bundled agents inherit the model selected by the user instead of pinning an Anthropic provider.
 - `skill-comply` is now part of the install manifest and npm distribution, with generated Python caches excluded from both install and package surfaces.
 - Release automation now verifies the tag is exactly on `origin/main`, fails closed on npm registry errors, tests the exact packed artifact across Linux, macOS, and Windows, publishes npm before creating the GitHub Release, and uses reviewed release notes.

+Commit `01779a4a` added final-review regressions for OpenCode configuration overrides, retained content digests, failed non-Claude install checkpoints, and reviewed-only GitHub Release notes. All four areas failed before the corresponding repairs.

 - `ecc memory` writes and `--body-file` reads failed on Windows under Node 22.12-22.16 and 24.0-24.1. libuv resolved path-based `stat()`/`lstat()` through `GetFileInformationByName` without setting the volume serial, while `fstat()` reported it, so the memory vault's TOCTOU guard rejected every operation. Fixed upstream in libuv 1.51.0; the guard no longer depends on the runtime's patch level. The guard's stat calls now request `BigInt` values, so Windows file IDs past `Number.MAX_SAFE_INTEGER` can no longer collapse two distinct files into one identity.
 - Selective reinstall now merges the prior ownership ledger, so later module additions do not orphan files from earlier installs and uninstall removes the complete managed surface.
 - Legacy Codex sync uninstall now uses ownership evidence, preserves user files, and requires an explicit opt-in for weaker marker-only cleanup.
+- Nasiko lifecycle operations now recover locks only after confirming the recorded owner is dead, preserve replacement locks, strictly reject malformed tar sizes, padding, terminators, and trailing data, and fail uninstall when staged files remain.
 - Hook, plan-canvas, session, memory, observer, skill-evolution, Discord delivery, and Windows compatibility regressions fixed across the runtime.

+- Nasiko lifecycle locks recover only when their recorded owner is confirmed dead. Its pinned archive parser rejects malformed boundaries, and incomplete uninstall cleanup returns an error with retained-file guidance.
 - `skill-comply` is included in both the install graph and npm archive. Python bytecode and pytest caches remain excluded.

 - The packed lifecycle covered npm installation, public CLI setup, cumulative Cursor install, drift detection, repair, uninstall, user-file preservation, Antigravity install/doctor/uninstall, and OpenCode install/doctor/uninstall.
 - Simulated hosted-runner `OPENCODE_CONFIG_DIR` and `XDG_CONFIG_HOME` overrides passed the adapter, MCP inventory, lifecycle, legacy migration, doctor, repair, list, and uninstall suites while explicit CLI environments continued to honor those overrides.

 - Default MCP connector set reduced to a single connector (`chrome-devtools`) per the new connector policy (`docs/MCP-CONNECTOR-POLICY.md`). The six previous defaults (`github`, `context7`, `exa`, `memory`, `playwright`, `sequential-thinking`) were retired after the June 2026 audit: their jobs are covered by skills wrapping CLIs/REST APIs (`github-ops`, `documentation-lookup`, `exa-search`, e2e skills) or by harness-native features (memory, extended thinking, web search). All six remain opt-in via `mcp-configs/mcp-servers.json`.
 - OpenCode home installs now use its canonical `~/.config/opencode` location, safely discover and migrate unchanged ECC-managed files from legacy `~/.opencode` installs, and preserve modified legacy files for review.

 ### Fixed
 
 - `ecc memory` writes and `--body-file` reads failed on Windows under Node 22.12-22.16 and 24.0-24.1. libuv resolved path-based `stat()`/`lstat()` through `GetFileInformationByName` without setting the volume serial, while `fstat()` reported it, so the memory vault's TOCTOU guard rejected every operation. Fixed upstream in libuv 1.51.0; the guard no longer depends on the runtime's patch level. The guard's stat calls now request `BigInt` values, so Windows file IDs past `Number.MAX_SAFE_INTEGER` can no longer collapse two distinct files into one identity.
 - Selective reinstall now merges the prior ownership ledger, so later module additions do not orphan files from earlier installs and uninstall removes the complete managed surface.
 - Legacy Codex sync uninstall now uses ownership evidence, preserves user files, and requires an explicit opt-in for weaker marker-only cleanup.
-- Nasiko lifecycle operations now recover locks only after confirming the recorded owner is dead, preserve replacement locks, strictly reject malformed tar sizes, padding, terminators, and trailing data, and fail uninstall when staged files remain.
+- The experimental Nasiko CLI lifecycle bridge now recovers locks only after confirming the recorded owner is dead, preserves replacement locks, strictly rejects malformed tar sizes, padding, terminators, and trailing data, and fails uninstall when staged files remain.

+# ECC 2.2 launch and rollback runbook
+
+Affaan is the only release operator for ECC 2.2. Everyone else may prepare,
+review, and verify the release candidate, but must not merge the release PR,
+create or push `v2.2.0`, change npm dist-tags, or publish the GitHub Release.
+
+## Availability model
+
+The default npm install remains `ecc-universal@2.1.0` until the final promotion
+step succeeds. The release workflow publishes 2.2.0 under the `staged` tag,
+reads its registry integrity back, compares those bytes with the exact archive
+that passed the three-platform lifecycle, and only then moves `latest` to
+2.2.0. There is no interval where `latest` points at an unpublished version.
+
+The native Claude marketplace install remains an independent install path
+throughout the npm rollout:
+
+```text
+/plugin marketplace add https://github.com/affaan-m/ECC
+/plugin install ecc@ecc
+```
+
+Never unpublish 2.1.0 or 2.2.0. npm dist-tags provide the reversible switch.
+
+## Current fallback baseline
+
+Before merge, confirm all of these:
+
+```bash
+npm view ecc-universal dist-tags --json
+npm view ecc-universal@2.1.0 dist.integrity
+curl -fsSIL https://registry.npmjs.org/ecc-universal/-/ecc-universal-2.1.0.tgz
+gh release view v2.1.0 --repo affaan-m/ECC
+```
+
+Expected:
+
+- `latest` is `2.1.0`.
+- The 2.1.0 tarball returns HTTP 200 and immutable caching headers.
+- A clean `npm install ecc-universal@2.1.0` succeeds.
+- A disposable managed install and uninstall succeed.
+
+The published 2.1 Cursor adapter can report one non-blocking doctor warning for
+an adapted Markdown link. This does not prevent installation or uninstall. ECC
+2.2 corrects the packed lifecycle and doctor behavior.
+
+## Preflight before Affaan merges
+
+1. PR #2863 must be mergeable and all required hosted checks must pass.
+2. The full local suite, npm audit, IOC scan, and exact packed lifecycle must
+   pass at the PR head.
+3. The packed README must describe 2.2 as available and contain no unpublished
+   2.2 warning.
+4. The Nasiko surface must say experimental CLI lifecycle bridge.
+5. `npm view ecc-universal@2.2.0 version` must return E404. Any other registry
+   error blocks the release.
+6. `npm view ecc-universal dist-tags --json` must still show `latest: 2.1.0`.
+
+## The release switch
+
+After Affaan merges PR #2863, wait for CI on the exact `origin/main` commit.
+From a clean, current `main` checkout:
+
+```bash
+git fetch origin main --tags
+git switch main
+git pull --ff-only origin main
+git status --short
+git rev-parse HEAD
+git rev-parse origin/main
+```
+
+The two commit IDs must match and `git status --short` must print nothing.
+Affaan then creates and pushes the signed release tag:
+
+```bash
+git tag -s v2.2.0 -m "ECC 2.2.0" HEAD
+git tag -v v2.2.0
+git push origin refs/tags/v2.2.0
+```
+
+That tag push is the only launch switch. The workflow then:
+
+1. Requires the tag commit to equal `origin/main`.
+2. Packs and hashes the npm archive once.
+3. Runs the exact archive on Linux, macOS, and Windows.
+4. Publishes the archive to the npm `staged` tag.
+5. Reads back and verifies registry integrity.
+6. Atomically promotes the verified version to `latest`.
+7. Creates the GitHub Release from the reviewed notes.
+
+## Immediate canary
+
+After the workflow succeeds:
+
+```bash
+npm view ecc-universal dist-tags --json
+npm view ecc-universal@2.2.0 version dist.integrity
+gh release view v2.2.0 --repo affaan-m/ECC
+npx --yes ecc-universal@2.2.0 setup --help
+npx --yes ecc-universal@latest setup --help
+```
+
+Expected:
+
+- Both exact-version and `latest` resolve to 2.2.0.
+- Registry integrity matches the workflow output.
+- The GitHub Release exists and uses the reviewed notes.
+- Both package invocations return the guided setup help.
+- The native Claude marketplace remains installable.
+
+Keep watching npm and GitHub install paths during the launch window. Treat an
+HTTP failure, integrity mismatch, missing public binary, or failed disposable
+install as critical.
+
+## Rollback
+
+If 2.2.0 has an install-critical regression, Affaan or another authorized npm
+owner restores the known installable fallback immediately:
+
+```bash
+npm dist-tag add ecc-universal@2.1.0 latest
+npm view ecc-universal dist-tags --json
+ECC_ROLLBACK_ROOT=$(mktemp -d)
+npm install --ignore-scripts --prefix "$ECC_ROLLBACK_ROOT" ecc-universal@2.1.0
+node "$ECC_ROLLBACK_ROOT/node_modules/ecc-universal/scripts/ecc.js" --help
+gh release edit v2.1.0 --repo affaan-m/ECC --latest
+```
+
+Then open a release incident, state that 2.2.0 remains available only by exact
+version while the incident is investigated, and repair forward with a new patch
+version. Do not unpublish either package version and do not reuse the `v2.2.0`
+tag.
