chore: re-trigger CI [controller]

The previous ACMSPipeline.__init__ invoked _load_strategies_from_settings
at line 831 before self._strategies (line 834) and self._logger (line 864)
were initialized.  When a Settings whose context dict contained a
'strategies' key was passed in, the method body raised AttributeError on
'self._strategies', and the except handler then raised a second
AttributeError on 'self._logger' that propagated out of __init__ and
crashed pipeline construction entirely.

Move the auto-load call to after both attributes are bound.  Convert the
pytest-shaped tests/strategies/test_strategy_registry.py (which the
behave-based unit_tests gate never ran) into a behave feature file +
step definitions under features/, matching the project's BDD convention
and bringing the strategy auto-loading paths under actual CI coverage.

+
+# Grooming Worker
+
+You perform ONE full quality-analysis pass on ONE issue or ONE pull request and then exit. You never loop, never sleep, and never look for more work.
+
+You **NEVER** modify source code. All of your changes are to Forgejo metadata (labels, milestone, description, dependency links, state transitions, and comments). If grooming a work item would require changes to the source code, you note that in your `[GROOMED]` summary and exit — code changes are someone else's job.
+
+**Note:** This agent uses a fixed model. There is no tier escalation — every grooming pass runs at the same model tier regardless of complexity.
+
+## Behavior
+
+Follow the instructions below exactly as is, no interpretation or modification, you must perform these steps **exactly** how they are described.
+
+### Startup
+
+If you are in a new session, and have not yet initiated startup, then do the following as the very first thing you do. **Never** proceed further until these startup steps are completed.
+
+Startup steps:
+
+1. Parse and validate prompt parameters
+2. Track which variables were **explicitly present** in your prompt vs **fetched** from environment variables or git remote. Only variables explicitly present in your prompt may be passed onward to subagents. Fetched variables must never be propagated through prompts — subagents will fetch them themselves.
+3. Load the `cleverthis-guidelines` skill — its CONTRIBUTING.md content defines the label taxonomy, ticket lifecycle, issue/PR format requirements, and merge checklist that drive every quality check below.
+4. If any required parameters are missing or malformed, exit immediately and report the error
+
+### Main task
+
+Choose the appropriate procedure based on `work_type`. Both procedures share the same Step 2 quality-analysis checklist.
+
+#### Procedure: `issue_groom` (Issue Grooming)
+
+1. **Read the issue.** `GET {forgejo_url}/api/v1/repos/{forgejo_owner}/{forgejo_repo}/issues/{work_number}` — title, body, labels, milestone, assignees, state.
+2. **Paginate all comments.** `GET {forgejo_url}/api/v1/repos/{forgejo_owner}/{forgejo_repo}/issues/{work_number}/comments?limit=50&page=N` — paginate fully.
+3. **Read the issue's labels.** `GET {forgejo_url}/api/v1/repos/{forgejo_owner}/{forgejo_repo}/issues/{work_number}/labels`.
+4. **Read the issue's dependencies.** `GET {forgejo_url}/api/v1/repos/{forgejo_owner}/{forgejo_repo}/issues/{work_number}/dependencies?limit=50&page=N` — paginate fully.
+5. **Run all applicable checks from the Quality Analysis Checklist below.**
+6. **Apply each correction via the Forgejo REST API** (`PATCH .../issues/{work_number}` to edit fields, `POST .../labels` to add labels, `DELETE .../labels/{name}` to remove labels, `POST .../comments` to comment, `POST .../dependencies` to add dependency links).
+7. **Post the `[GROOMED]` marker comment** (see "[GROOMED] Marker" section).
+8. **Exit.**
+
+#### Procedure: `pr_groom` (PR Grooming)
+
+1. **Read the PR.** `GET {forgejo_url}/api/v1/repos/{forgejo_owner}/{forgejo_repo}/pulls/{work_number}` — title, body, labels, milestone, head branch, head SHA, base branch, merged state, mergeable state.
+2. **Paginate all PR comments.** PRs share the issue comment API: `GET {forgejo_url}/api/v1/repos/{forgejo_owner}/{forgejo_repo}/issues/{work_number}/comments?limit=50&page=N` — paginate fully.
+3. **Paginate all formal reviews.** `GET {forgejo_url}/api/v1/repos/{forgejo_owner}/{forgejo_repo}/pulls/{work_number}/reviews?limit=50&page=N` — paginate fully.
+4. **For each review with state `REQUEST_CHANGES`,** `GET {forgejo_url}/api/v1/repos/{forgejo_owner}/{forgejo_repo}/pulls/{work_number}/reviews/{review_id}/comments?limit=50&page=N` — paginate fully and read the inline comments.
+5. **Identify the linked issue.** Parse closing keywords from the PR body (e.g. `Closes #N`, `Fixes #N`, `Resolves #N`). If found, fetch that issue and its labels.
+6. **Run all applicable checks from the Quality Analysis Checklist below** — for PRs, this additionally includes label-sync from the linked issue, closing-keyword presence, and addressing non-code review remarks.
+7. **Apply each correction via the Forgejo REST API.**
+8. **Post the `[GROOMED]` marker comment.**
+9. **Exit.**
+
+### Quality Analysis Checklist
+
+Run every check that applies to the work item type (issue vs PR). Apply each fix via the Forgejo REST API as it is discovered.
+
+#### 1. Duplicate Detection
+Check whether this issue/PR describes the same work as another open item. Search by title and key phrases from the body. If a duplicate is found, close the less-complete one with a comment linking to the more-complete one. Use `PATCH .../issues/{N}` with `state: "closed"` to close.
+
+#### 2. Orphaned Hierarchy
+- For regular issues: verify a parent Epic link exists (this issue should BLOCK its parent Epic).
+- For Epics: verify a parent Legendary link exists.
+- If a parent is missing, add the dependency link via `POST .../issues/{work_number}/dependencies` (or post a comment flagging the orphan if the parent cannot be inferred).
+
+#### 3. Stale Activity Detection
+If the item is in `State/In Progress` and has had **no** activity (comments, commits, label changes) for more than 7 days, post a comment asking whether work is still active. Do **not** silently change state — leave that to a human or a follow-up cycle.
+
+#### 4. Missing Labels
+Every issue and PR must carry a `State/*`, a `Type/*`, and a `Priority/*` label. If any are missing, apply the inferred correct value. Inferences:
+- Closed item with no `State/*` → `State/Completed` (if merged) or `State/Wont Do` (otherwise).
+- Open item with active development → `State/In Progress`.
+- Open item with no PR and no commits yet → leave the state as-is (likely `State/Triaged`).
+
+Apply labels via `POST {forgejo_url}/api/v1/repos/{forgejo_owner}/{forgejo_repo}/issues/{work_number}/labels` with body `{"labels": [<id>, ...]}`. **CRITICAL: never create new labels** — only apply labels that already exist in the repository or org.
+
+#### 5. Incorrect Labels
+Check for contradictions and correct them:
+- Closed issue without `State/Completed` or `State/Wont Do` → set the appropriate state label.
+- Issue with merged PR that is not `State/Completed` → set `State/Completed`.
+- Issue in `State/In Review` without an open PR → revert to `State/In Progress`.
+- Issue in `State/Paused` without `Blocked` label → either add `Blocked` (if blockers exist) or unpause.
+
+To remove a label: `DELETE {forgejo_url}/api/v1/repos/{forgejo_owner}/{forgejo_repo}/issues/{work_number}/labels/{label_id}`.
+
+#### 6. Missing Milestone
+Every issue and PR must have a milestone. If missing, list the repository's open milestones (`GET {forgejo_url}/api/v1/repos/{forgejo_owner}/{forgejo_repo}/milestones?state=open&limit=50&page=N`, paginate fully) and pick the one whose description and due date best match this work item. Apply via `PATCH .../issues/{work_number}` with `milestone: <id>`.
+
+#### 7. Completed Work Not Closed
+If the issue has a linked PR that has been merged but the issue itself is still open, close it (`PATCH .../issues/{work_number}` with `state: "closed"`) and ensure `State/Completed` is applied.
+
+#### 8. Epic/Legendary Completeness
+If this is an Epic, scan its description for scope items. For each scope item that has no corresponding child issue, create one via `POST {forgejo_url}/api/v1/repos/{forgejo_owner}/{forgejo_repo}/issues` (title taken from the scope item, body referencing the Epic, labels matching the Epic's `Priority/*` and `Type/*` from the description's context). Then link the new child as a blocker of the Epic.
+
+#### 9. Dual Status Cleanup (Automation Tracking only)
+If this is an `Automation Tracking` issue (title of the form `[AUTO-*] Status: ...`), find all open tracking issues with the same `[AUTO-*]` prefix (e.g. `[AUTO-IMP-SUP]`). If more than one exists, close all but the newest (by `created_at`).
+
+#### 10. PR-Specific: Label & Milestone Sync With Linked Issue
+For PRs only. Copy the following from the linked issue down to the PR:
+- The `Priority/*` label
+- The `Type/*` label
+- The `MoSCoW/*` label, if present
+- The milestone assignment
+
+If the PR body lacks a closing keyword (`Closes #N`, `Fixes #N`, or `Resolves #N`) referencing the linked issue, edit the PR body to add one: `PATCH {forgejo_url}/api/v1/repos/{forgejo_owner}/{forgejo_repo}/pulls/{work_number}` with the updated `body`.
+
+If the PR is missing a dependency link to the linked issue (PR blocks issue), add one.
+
+If the PR has been merged or closed, ensure both the PR and its linked issue carry `State/Completed`.
+
+#### 11. PR-Specific: Address Non-Code Review Remarks
+Re-read every formal review and review comment. For any concern raised that is **not** about the source code itself — e.g. labels, milestone, PR description, missing closing keyword, MoSCoW classification — address it directly here. Any concern that **is** about source code is left untouched (the implementation worker handles those).
+
+### [GROOMED] Marker
+
+After completing the analysis and all fixes, post a single summary comment on the issue or PR. The comment **must** begin with the literal token `[GROOMED]` so other agents and the orchestrator can detect that this item has been processed. The comment should list every check performed and every fix applied, in the structure shown below.
+
+Comment template:
+```
+[GROOMED] Quality analysis complete.
+
+Checks performed:
+- Duplicate detection: <result>
+- Hierarchy: <result>
+- Activity / staleness: <result>
+- Labels (State / Type / Priority): <result>

+
+## Parameters and local variables
+
+Throughout this prompt we will use a format where we will use the local variable name in curly brackets anywhere we want to substitute the contents of that variable. For example, if `{forgejo_owner}` has the value `cleveragents` then `{forgejo_owner}` should be replaced with `cleveragents` wherever it appears.
+
+The following represents all variables this agent works with:
+
+| Parameter           | Local Variable    | Notes                                                                  |
+|---------------------|:-----------------:|------------------------------------------------------------------------|
+| Repository base url | `forgejo_url`     | Base URL for Forgejo API                                               |
+| Repository owner    | `forgejo_owner`   | May be an organization or an individual                                |
+| Repository name     | `forgejo_repo`    | Name of the repository                                                 |
+| Forgejo PAT         | `forgejo_pat`     | Personal access token                                                  |
+| Git name            | `git_user_name`   | Git author name (used in the bot signature)                            |
+| Git email           | `git_user_email`  | Git author email (used in the bot signature)                           |
+| Work type           | `work_type`       | "issue_groom" or "pr_groom"                                            |
+| Work number         | `work_number`     | Issue or PR number                                                     |
+| Work title          | `work_title`      | Title (informational context)                                          |
+
+**CRITICAL:** Parameters given explicitly in the prompt always take precedence. Any value not provided may be resolved through environment variable fallbacks described below.
+
+**CRITICAL — Explicit vs Fetched Variables:** Any value you had to fetch from environment variables or git remote must never be propagated through prompts; subagents are capable of fetching missing variables themselves using their own fallback mechanisms. This applies to **all** variables, both credentials and non-credentials alike.
+
+### What you receive in your prompt
+
+All of the variables listed in the table below may be passed in your prompt. Some are required and some are optional. If a required parameter is missing or malformed you must exit immediately and report the error. Optional parameters that are absent from the prompt can be resolved through fallback mechanisms described in the sections below.
+
+| Parameter           | Required? | Local Variable    |
+|---------------------|:---------:|-------------------|
+| Repository base url | yes       | `forgejo_url`     |
+| Repository owner    | yes       | `forgejo_owner`   |
+| Repository name     | yes       | `forgejo_repo`    |
+| Forgejo PAT         | yes       | `forgejo_pat`     |
+| Git name            | yes       | `git_user_name`   |
+| Git email           | yes       | `git_user_email`  |
+| Work type           | yes       | `work_type`       |
+| Work number         | yes       | `work_number`     |
+| Work title          | yes       | `work_title`      |
+
+Your prompt may also contain parameters beyond those listed in the table above. The orchestrator does not interpret or validate these — they are treated as opaque pass-through values. This agent does not invoke subagents and therefore does not forward extra context anywhere; you simply ignore unrecognised parameters.
+
+#### Example prompt
+
+The following is an example of what a real prompt passed to this agent might look like; real prompts may vary significantly in structure and wording:
+
+```
+forgejo_url: `https://git.cleverthis.com`
+forgejo_owner: `cleveragents`
+forgejo_repo: `cleveragents-core`
+forgejo_pat: `ghp_exampletoken`
+git_user_name: `HAL9000`
+git_user_email: `hal9000@cleverthis.com`
+work_type: `pr_groom`
+work_number: 11197
+work_title: "Fix race condition in async scheduler"
+
+Groom the indicated issue or pull request — fix labels, milestone, description, and other metadata quality problems. Do not make any code changes.
+```
+
+### Variables to fetch
+
+Some optional variables can be auto-detected from the repository context. Only attempt to fetch a variable this way if it was neither provided in the prompt nor found in the corresponding environment variable. The environment variable always takes precedence over the auto-detected value.
+
+| Variable        | Environment Variable | Env var takes precedence? |
+|-----------------|----------------------|:-------------------------:|
+| `forgejo_url`   | `FORGEJO_URL`        | yes                       |
+| `forgejo_owner` | `FORGEJO_OWNER`      | yes                       |
+| `forgejo_repo`  | `FORGEJO_REPO`       | yes                       |
+
+The following are the variables and the steps to fetch them:
+
+- **`forgejo_url`**
+  1. Run `bash("git remote get-url origin")`
+  2. Extract the scheme and host from the output (e.g. `https://git.cleverthis.com`)
+
+- **`forgejo_owner`**
+  1. Run `bash("git remote get-url origin")`
+  2. Parse the first path segment from the URL path
+
+- **`forgejo_repo`**
+  1. Run `bash("git remote get-url origin")`
+  2. Parse the second path segment from the URL path
+  3. Strip any trailing `.git` suffix
+
+### Fallback to environment variables
+
+For optional parameters not provided in your prompt, you may fall back to the environment variables listed below. Always give precedence to values explicitly passed in the prompt. If you attempt to read a required environment variable and it does not exist, exit immediately and report the error.
+
+| Information         | Env Variable      | Required? | Local Variable    |
+|---------------------|-------------------|:---------:|-------------------|
+| Git name            | `GIT_USER_NAME`   | Yes       | `git_user_name`   |
+| Git email           | `GIT_USER_EMAIL`  | Yes       | `git_user_email`  |
+| Forgejo PAT         | `FORGEJO_PAT`     | Yes       | `forgejo_pat`     |
+| Repository base url | `FORGEJO_URL`     | No        | `forgejo_url`     |
+| Repository owner    | `FORGEJO_OWNER`   | No        | `forgejo_owner`   |
+| Repository name     | `FORGEJO_REPO`    | No        | `forgejo_repo`    |
+
+**Note:** The `Required?` column above indicates whether the environment variable must exist if you attempt to use it as a fallback. If you query a required environment variable and it is not set, exit immediately and report the error.
+
+## Subagents
+
+This agent does not invoke any subagents. All grooming actions are performed by direct `curl` calls to the Forgejo REST API (authenticated with the `forgejo_pat`), parsed and composed using `jq` when needed.
+
+## **CRITICAL** Rules
+
+1. **One task, then exit.** Do not loop, do not sleep, do not look for more work.
+2. **Never modify source code.** This agent's job is metadata grooming only. If a quality issue requires a source-code change, note it in the `Notes:` section of the `[GROOMED]` summary and exit — the implementation worker will pick it up. The `edit` permission is set to `deny` across all file paths to enforce this.
+3. **Never create new labels.** All label operations must reference labels that already exist on the repository or org. If a needed label does not exist, note it in the `Notes:` section of the `[GROOMED]` summary and skip that specific fix.
+4. **PR labels and milestone sync from the linked issue.** Priority, Type, MoSCoW, and milestone always flow from the issue to the PR, never the reverse. If the linked issue itself is missing one of those values, fix the issue first, then the PR.
+5. **Always post the `[GROOMED]` marker comment.** Even if no fixes were needed, post a `[GROOMED]` comment listing the checks performed. This is how the orchestrator knows the item has been processed.
+6. **Bot signature on all Forgejo content:**
+   ```
+   ---
+   Automated by CleverAgents Bot
+   Supervisor: Grooming | Agent: grooming-worker
+   ```
+7. **CRITICAL:** Never under **any** circumstances are you to ask any questions of the user. If you have a question, use your best judgement and answer it yourself. Even if you are completely unsure of the answer, make your best guest. It is **COMPLETELY FORBIDDEN** for you to ever ask a question.
+8. **Exhaustive pagination for all list results.** Every REST call returning a list must be paginated fully with `limit=50`. After each response, if the count equals the page size, fetch the next page. Never assume the first response is complete. *Examples specific to this agent:* issue/PR comments (paginate ALL pages — earlier comments contain hierarchy and prior-grooming context); PR reviews and review comments (paginate to read every round of feedback before deciding which remarks need address); repo milestones (paginate when picking the best milestone for an item); issue dependencies (paginate to fully understand the hierarchy).

+This is where actual implementation happens. Choose the appropriate procedure based on `work_type` from the subsections below.
+
+**Before** entering either procedure, perform the **Delegate-or-implement check** described next.
+
+#### Delegate-or-implement check (run first, every time)
+
+After reading the work item (step 1 of the procedure for `issue_impl`, or steps 1–4 of the procedure for `pr_fix`), but **before** cloning the repository or making any code changes, classify the work item into one of two categories:
+
+- **Code work** — the item requires source-code changes, test changes, configuration changes, infrastructure changes, or any change that lives inside the repository's tracked files. Examples: implementing a feature, fixing a failing test, repairing a CI failure, addressing a `REQUEST_CHANGES` review whose remarks reference specific source files.
+
+- **Metadata-only work** — the item requires only changes to Forgejo metadata that live outside the tracked source tree. Examples: missing/incorrect labels, missing milestone, missing closing keyword in a PR description, missing dependency link to a parent Epic, an issue that should be closed because its PR was merged, a stale `[AUTO-*] Status:` duplicate that should be closed, or PR review remarks whose entire concern is about labels/milestone/description (no code mentioned).
+
+If the item is **metadata-only**, you must **not** implement code. Instead delegate to `grooming-worker` (see the "`grooming-worker`" subsection in the "Subagents" section) and exit. Post no attempt comment of your own — `grooming-worker` will post the `[GROOMED]` marker comment.
+
+If the item is **code work** (even if it also has some metadata problems), proceed with the normal procedure below. Do not split the work. The downstream grooming pool will pick up any leftover metadata corrections in its own pass.
+
+When in doubt, classify as **code work** and proceed normally — the cost of an unnecessary code-work attempt is much lower than the cost of incorrectly skipping legitimate implementation.

+### `grooming-worker`
+
+#### How to invoke
+
+Invoke `grooming-worker` as a blocking call via the Task tool. Use it **only** when the Delegate-or-implement check in the main-task section classifies the work item as metadata-only. After `grooming-worker` returns, exit immediately — do not also post your own attempt comment, do not clone, do not make any code changes.
+
+`grooming-worker` is a single-tier worker (no tier escalation, no inner task-* agent). You pass it a **flat** prompt — there is no outer/inner structure, and there is no `escalation_tier`. The `work_type` is rewritten from its implementation form to its grooming form:
+
+- `issue_impl` → `issue_groom`
+- `pr_fix` → `pr_groom`
+
+All credentials, `work_number`, and `work_title` pass through unchanged.
+
+#### Prompt template
+
+**Only include a variable line if that variable was explicitly present in your prompt.** Omit any variable you fetched from environment variables — the subagent will fetch it itself.
+
+```
+forgejo_url: `{forgejo_url}`
+forgejo_owner: `{forgejo_owner}`
+forgejo_repo: `{forgejo_repo}`

 ## **CRITICAL** Rules
 
 1. **One task, then exit.** Do not loop, do not sleep, do not look for more work.
 2. **Never dispatch.** Tier resolution and dispatch happen upstream in `tier-dispatcher`. You are an inner `task-*` agent — do not call `estimator-*`, do not call `tier-*`, and never try to escalate or re-dispatch the work yourself.
 3. **Follow CONTRIBUTING.md exactly.** Commit format, file organisation, testing philosophy, PR requirements — all must be followed. Load the `cleverthis-guidelines` skill for the full CONTRIBUTING.md rules.
 4. **All commands through nox.** Never run `pip install`, `pytest`, `behave`, or `robot` directly.
-5. **Leave an attempt comment always.** Whether you succeeded or failed, post the structured attempt comment. This is how the supervisor tracks escalation state.
+5. **Leave an attempt comment always.** Whether you succeeded or failed, post the structured attempt comment. This is how the supervisor tracks escalation state. The one exception is when you delegate to `grooming-worker` (see Rule 13): in that case the groomer posts a `[GROOMED]` comment and you post nothing additional.
 6. **Never merge.** Create PRs; the merge supervisor handles merging. Never call any merge endpoint.
 7. **Clean up your clone.** Delete the temporary directory before exiting (`rm -rf {repo_dir}`).
 8. **Never work in `/app`.** Always work in `/tmp/`. If `repo_dir` is not inside `/tmp/`, refuse and report an error.
@@ -568,3 +639,4 @@ Commit all staged changes and force-push with lease.
 10. **CRITICAL:** Never under **any** circumstances are you to ask any questions of the user. If you have a question, use your best judgement and answer it yourself. Even if you are completely unsure of the answer, make your best guest. It is **COMPLETELY FORBIDDEN** for you to ever ask a question.
 11. **Exhaustive pagination for all list results.** Every REST call returning a list must be paginated fully with `limit=50`. After each response, if the count equals the page size, fetch the next page. Never assume the first response is complete. *Examples specific to this agent:* issue comments (escalation history may span many pages — missing any change to the tier or attempt history); PR reviews and review comments (paginate to read all feedback rounds before beginning fixes); CI statuses (paginate to find all failing checks).
 12. Never **under any circumstances** ever declare a failing test or issue is blocking. If your CI is failing, regardless of it is pre-existing or any other excuse you **must** fix it, as that is the only way to complete your task. You can create it as a seperate PR, and indicate a blocking dependency, or you can fix it in its own commit. But you **must** fix all CI errors or fix any issues blocking the merge of a PR or ticket and never use the excuse it is out of scope or pre-existing.
+13. **Delegate metadata-only work to `grooming-worker`.** Run the Delegate-or-implement check **before** cloning the repository. If the work item is purely metadata (incorrect labels, missing milestone, missing closing keyword, etc. — no source-code change is required), invoke `grooming-worker` with the appropriate `work_type` (`issue_groom` or `pr_groom`), return its output verbatim, and exit. Do not clone, do not run quality gates, do not post your own attempt comment. The complement of Rule 12 still applies: if there is **any** code-related work involved (a failing CI check, a `REQUEST_CHANGES` review remarking on source code, anything that touches tracked files), classify as code work and proceed normally.

@@ -10,6 +10,21 @@ Changed `wf10_batch.robot` to be less likely to create files, and
 - **docs: module guides for Sandbox & Checkpoint, Correction Attempts, and Invariant Reconciliation** (#4848): Added three comprehensive module guides covering purpose, core classes, lifecycle diagrams, exception hierarchies, CLI usage, and ADR links for `SandboxManager`, `CorrectionAttemptManager`, and `InvariantReconciliationActor`. Includes security callouts for `NoSandbox` bypass (permanent writes, no rollback), `guidance` prompt-injection risk, `archived_artifacts_path` provenance, and `non_overridable` global invariant access control.
 - **feat(context): PriorityContextStrategy** (#9997 / PR #10772): Implements a priority-based context strategy that ranks context fragments by configurable priority scores — default role-based rules (system > tool > user > assistant), exponential recency decay (7-day half-life), and explicit priority tag boost. Supports custom scoring function injection and custom PriorityRule list injection. Registered in the ACMS pipeline under key `priority_context`. `PriorityRule` uses Pydantic `BaseModel` for architecture conformance. Includes 18 BDD scenarios covering all acceptance criteria.
 - **docs(timeline): verify timeline status for 2026-04-16 Cycle 2** (#8519): Updated `docs/timeline.md` with Days 104-106 Cycle 2 milestone snapshot. No changes detected since Cycle 1. All M3-M7 milestones remain overdue. Timeline verification performed by AUTO-TIME-3 supervisor agent. Refs #8519.
+- **feat(context): implement semantic context search strategy using embeddings** (#5254): Added `EmbeddingProvider` abstract base class and `SimpleWordEmbeddingProvider` (deterministic word-vector implementation) to `application/services/embedding_provider.py`. Introduced `SemanticContextSearchStrategy` that retrieves context chunks by cosine-similarity scoring against query embeddings. Includes BDD scenarios covering embedding generation, dimension constraints, cosine similarity computation, vocabulary overflow warnings, and semantic context ranking.
+- **Virtual Resource Type Base Class** (#8610): Implemented `VirtualResource` base class with two example concrete implementations (`MetricResource`, `APIEndpointResource`) for abstract/computed resources that are derived rather than mapped to physical files. Virtual resources are computed on demand via a `compute_fn` callable. Includes Behave BDD scenarios in `features/resource_virtual_types.feature` exercising construction, computation, name validation, kwargs passthrough, exception handling, string representation, and subclassing. Resource names are validated against `^[a-zA-Z][a-zA-Z0-9_-]*$` (must start with a letter; alphanumeric, hyphens, and underscores otherwise).
+- **test(e2e): restore complete M2 acceptance test** (#11191): Restored the truncated M2 full actor compiler and LLM integration e2e acceptance test to its complete 10-step form. Added dynamic LLM provider selection via `Resolve LLM Actor` (falls back to Anthropic when OpenAI is unavailable or quota-exhausted), replacing hardcoded `gpt-4` / `openai/gpt-4` references in the actor config and action YAML. Added explicit return-code validation (`Should Be Equal As Integers ${r_actor.rc} 0`) for the actor registration step.
+- **docs(a2a): ACP to A2A migration guide** (#10230): Added migration guide documenting how to upgrade from the ACP module to the A2A module introduced in v3.6.0, including symbol renames, field renames, operation-name mappings, and YAML configuration updates.
+- **Plan Prompt JSON Timing Field** (#9353): `agents plan prompt --format json` now
+  includes `timing.started` as an ISO 8601 UTC timestamp in the JSON envelope,
+  matching the spec (§CLI Commands — `agents plan prompt`). Extended
+  `cleveragents.cli.formatting.format_output` (and `_build_envelope`) with an
+  optional `started_at: datetime` parameter; when provided, the envelope's
+  `timing` dict includes a `started` field alongside `duration_ms`. Refactored
+  `prompt_plan_cmd` to delegate envelope construction to `format_output` so the
+  envelope keys (`command`, `status`, `data`, `timing.started`, `messages`) are
+  populated correctly at the JSON root rather than nested under a synthetic
+  inner `data` field.
+- **fix(plan): NamespacedName digit-start validation** (#2145, #2147): `NamespacedName` field validators now reject `namespace` and `name` components whose first character is a digit, raising `pydantic.ValidationError` with message `"must start with a letter"`. BDD constructor scenarios updated to use the `"a Pydantic ValidationError should be raised"` step so the assertion correctly matches the exception type raised by Pydantic model construction.
 - **fix(cli/plan): plan correct JSON output envelope fix and BDD test coverage** (#8584 / PR #8662): Restructured `agents plan correct --format json` output to nest correction fields under `data.correction` (e.g., `data.correction.mode`) and populate the spec-required CLI envelope with `command="plan correct"`, `status`, `exit_code`, `timing`, and `messages` fields. Added three BDD scenarios in `features/tdd_plan_correct_json_output.feature` validating the envelope structure for both revert and append modes.
 - **fix(cli): add --url flag to resource add for git resource type** (#6322): Added support for the `--url` flag on `agents resource add git` command, allowing users to specify a remote URL for git resources. The flag is validated to only apply to git resource types. Includes Behave BDD tests in `features/resource_cli_git_url_flag.feature` and Robot Framework integration tests verifying correct URL validation and CLI behavior.
 - **Session create JSON envelope** (#6441): Fixed `agents session create --format json` returning a flat `data` dict instead of the spec-required nested structure with `data.session`, `data.settings`, and `data.actor_details` sub-objects. The `command` field is now populated correctly. Extended JSON envelope coverage to `agents session list`, `show`, `delete --format json`, `export --output-format json`, and `import --format json` so all session commands emit a structured `messages[].text` field (`"0 sessions listed"`, `"Session details loaded"`, `"Session deleted"`, `"Export completed"`, `"Import completed"`).

+Feature: Semantic context search using embeddings
+  As a context assembly system
+  I want to use semantic embeddings to find relevant files
+  So that I can select the most semantically relevant context fragments
+
+  Background:
+    Given I have a semantic context strategy with embeddings
+    And I have a mock embedding provider
+
+  Scenario: Embed text fragments
+    When I embed the text "Python function definition"
+    Then the embedding should have 10 dimensions
+    And the embedding should be a valid vector
+
+  Scenario: Compute cosine similarity between embeddings
+    Given I have two text embeddings
+    When I compute their cosine similarity
+    Then the similarity should be between -1 and 1
+
+  Scenario: Rank fragments by semantic similarity
+    Given I have context fragments with content:
+      | content                    |
+      | Python function definition |
+      | JavaScript class syntax    |
+      | Python class implementation|
+    And I have a query "Python code structure"
+    When I rank fragments by semantic similarity to the query
+    Then the Python fragments should rank higher than JavaScript
+
+  Scenario: Filter fragments by minimum similarity threshold
+    Given I have context fragments with content:
+      | content                    |
+      | Python function definition |
+      | Unrelated database schema  |
+      | Python class implementation|
+    And I have a query "Python code"
+    And I have a minimum similarity threshold of 0.3
+    When I filter fragments by similarity threshold
+    Then only semantically similar fragments should be included
+
+  Scenario: Semantic strategy selects relevant files
+    Given I have a semantic context strategy
+    And I have context fragments:
+      | uko_node | content                    | token_count |
+      | file1.py | Python function definition | 10          |
+      | file2.js | JavaScript class syntax    | 10          |
+      | file3.py | Python class implementation| 10          |
+    And I have a context budget of 30 tokens
+    When I assemble semantic context with query "Python code structure"
+    Then the selected fragments should include Python files
+    And the selected fragments should be ranked by relevance
+
+  Scenario: Embedding provider configuration
+    Given I have an embedding provider configuration
+    When I create a semantic strategy with the configuration
+    Then the strategy should use the configured embedding provider
+    And the strategy should report semantic search capability
