From 1971d40a653e748673e7b12aaa26e9e4572306a0 Mon Sep 17 00:00:00 2001 From: James Devine Date: Sun, 14 Jun 2026 21:26:38 +0100 Subject: [PATCH 01/13] refactor(ado-script): promote PR helpers to shared/ for upcoming contributors Stage 0 of the execution-context contributor build-out (plan.md, session artifact). Pure file move; no behavioural change. Moves four helper modules from scripts/ado-script/src/exec-context-pr/ into scripts/ado-script/src/shared/ so the upcoming pipeline, ci-push, schedule, and workitem contributors can reuse them without fragmenting the workspace with an exec-context-common/ sibling. Files moved (with git mv, preserving history): - git.ts (bearerEnv + runGit / gitOk wrappers) - merge-base.ts (synthetic-merge detection + progressive-deepening fetch) - validate.ts (identifier allowlist regexes + sanitizeForPrompt) - prompt.ts (success / failure prompt-fragment writers + appender) And their __tests__/ siblings. shared/index.ts gains four new barrels (git, mergeBase, validate, prompt). exec-context-pr/index.ts now imports from ../shared/ instead of ./. Doc references in docs/ado-script.md and src/compile/extensions/exec_context/pr.rs updated to match.

Adds the `manual` contributor: activates whenever the agent declares any `parameters:` block and stages requestor identity + a JSON snapshot of parameter values for manually-queued ADO builds. Artefacts staged under `aw-context/manual/`: - `requested-for` — `Build.RequestedFor` display name - `requested-for-email` — only when `manual.include-email: true` - `parameters.json` — `{name: value}` snapshot of user-declared params (clearMemory is auto-injected at IR-build time so it is naturally absent) Front-matter surface (all optional): execution-context: manual: enabled: true # default when parameters: declared include-email: false # hygiene default; opt-in Trust boundary: no bearer (SYSTEM_ACCESSTOKEN NOT projected), no network, no REST. Parameter NAMES are validated as ADO identifiers upstream and re-checked at emit time by the contributor as defence-in-depth. Parameter VALUES are JSON-serialised (escape-safe) when written to disk and sanitised via shared/validate.sanitizeForPrompt before any prompt interpolation. Runtime gate: `eq(variables['Build.Reason'], 'Manual')` — non-manual queues skip the step at zero cost.

From f70b13ba4aeffd5f10a701ab818ea420a2254d6b Mon Sep 17 00:00:00 2001 From: James Devine Date: Sun, 14 Jun 2026 22:27:04 +0100 Subject: [PATCH 03/13] feat(exec-context): add pipeline contributor + shared/build.ts MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Stage 2 of the execution-context contributor build-out (plan.md). Adds the `pipeline` contributor: activates whenever the agent declares an `on.pipeline` trigger and stages upstream-build metadata for `resources.pipelines`-triggered ADO builds. Also introduces `scripts/ado-script/src/shared/build.ts` — the Build REST helper module that Stages 3 (ci-push), 5 (schedule), and 6 (pr.checks) will also consume. Two exports today: `getBuildById`, `listArtifacts`. Both wrap the existing `withRetry` machinery from shared/ado-client.ts for transient-error resilience. Artefacts staged under `aw-context/pipeline/`: - `upstream-build-id` — numeric Build ID - `upstream-source-sha` — Build.sourceVersion - `upstream-source-branch` — Build.sourceBranch - `upstream-status` — translated BuildResult (succeeded/...) - `upstream-definition` — pipeline name - `upstream-artifacts.json` — artifact INDEX (bytes NOT downloaded) - `error.txt` — present only on REST failure Front-matter surface (all optional): execution-context: pipeline: enabled: true # default when on.pipeline is configured Trust boundary: SYSTEM_ACCESSTOKEN is mapped only into the precompute step's env block (never the agent step); used as bearer for the Build REST API. Never written to disk, never logged. Build.TriggeredBy.* identifiers are validated for shape (numeric build id, GUID project id) before any REST call. Bundle uses the same soft-fail posture as the PR contributor — REST failure writes error.txt + failure-fragment that tells the agent NOT to invent an upstream-build status. Runtime gate: `eq(variables['Build.Reason'], 'ResourceTrigger')`. Wiring: - New `PipelineContextContributor` in src/compile/extensions/exec_context/pipeline.rs - `Contributor::Pipeline` variant in contributor.rs - `pipeline_contributor_will_activate` helper in mod.rs (OR'd into `any_contributor_active` aggregate; pub-re-exported via extensions/mod.rs for collect_extensions) - `EXEC_CONTEXT_PIPELINE_PATH` + `exec_context_pipeline_active: bool` on AdoScriptExtension; OR'd into the install/download gate - `PipelineContextConfig` on ExecutionContextConfig - New TS bundle scripts/ado-script/src/exec-context-pipeline/ (with __tests__/index.test.ts; 12 vitest cases incl. trust-boundary) - New scripts/ado-script/src/shared/build.ts + __tests__/build.test.ts (5 vitest cases incl. retry + non-transient rethrow) - Build.TriggeredBy.* (BuildId/DefinitionId/DefinitionName/ProjectID) added to ADO macro allowlist in ir/env.rs Validation: - cargo build / cargo test (2030 Rust tests, 0 failures) / clippy clean - npm typecheck / test (316 tests) / build / smoke (6 tests) Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> --- .github/workflows/release.yml | 2 +- docs/ado-script.md | 30 +- docs/execution-context.md | 68 +++- scripts/ado-script/.gitignore | 1 + scripts/ado-script/package.json | 7 +- .../__tests__/index.test.ts | 304 ++++++++++++++++++ .../src/exec-context-pipeline/index.ts | 304 ++++++++++++++++++ .../src/shared/__tests__/build.test.ts | 93 ++++++ scripts/ado-script/src/shared/build.ts | 77 +++++ scripts/ado-script/src/shared/index.ts | 4 + src/compile/extensions/ado_script.rs | 26 +- .../extensions/exec_context/contributor.rs | 7 +- src/compile/extensions/exec_context/mod.rs | 54 +++- .../extensions/exec_context/pipeline.rs | 247 ++++++++++++++ src/compile/extensions/mod.rs | 9 +- src/compile/ir/env.rs | 12 + src/compile/types.rs | 42 +++ 17 files changed, 1262 insertions(+), 25 deletions(-) create mode 100644 scripts/ado-script/src/exec-context-pipeline/__tests__/index.test.ts create mode 100644 scripts/ado-script/src/exec-context-pipeline/index.ts create mode 100644 scripts/ado-script/src/shared/__tests__/build.test.ts create mode 100644 scripts/ado-script/src/shared/build.ts create mode 100644 src/compile/extensions/exec_context/pipeline.rs diff --git a/.github/workflows/release.yml b/.github/workflows/release.yml index cb4de344..d5485327 100644 --- a/.github/workflows/release.yml +++ b/.github/workflows/release.yml @@ -77,7 +77,7 @@ jobs: run: | set -euo pipefail cd scripts - zip -r ../ado-script.zip ado-script/gate.js ado-script/import.js ado-script/exec-context-pr.js ado-script/exec-context-pr-synth.js ado-script/exec-context-manual.js + zip -r ../ado-script.zip ado-script/gate.js ado-script/import.js ado-script/exec-context-pr.js ado-script/exec-context-pr-synth.js ado-script/exec-context-manual.js ado-script/exec-context-pipeline.js - name: Upload release assets env: diff --git a/docs/ado-script.md b/docs/ado-script.md index 0507087b..ae571bd8 100644 --- a/docs/ado-script.md +++ b/docs/ado-script.md @@ -21,6 +21,11 @@ pipeline** as runtime helpers.

From 456fb957ec3017d791819b77470e02f7f350f303 Mon Sep 17 00:00:00 2001 From: James Devine Date: Sun, 14 Jun 2026 22:45:50 +0100 Subject: [PATCH 04/13] feat(exec-context): add ci-push contributor (default OFF) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Stage 3 of the execution-context contributor build-out (plan.md). Adds the `ci-push` contributor: stages "since last green build on this branch" diff context for non-PR push builds. Default-OFF (opt-in via `ci-push.enabled: true`) because the helper does ADO REST + git fetch deepening that adds startup latency. Runtime gate: `or(eq(Build.Reason, IndividualCI), eq(Build.Reason, BatchedCI))`. Artefacts staged under `aw-context/ci-push/`: - `current-sha` — Build.SourceVersion - `previous-sha` — SHA of the last successful build of this pipeline on this branch (REST lookup) - `base.sha` — git merge-base(previous, current) - `commits.txt` — `git log previous..current --oneline` - `changed-files.txt` — `git diff --name-status previous..current` - `error.txt` — present only on failure Failure paths (each gets the failure fragment that tells the agent NOT to claim "diff is empty"): - No previous successful build (first push / all prior failed / pruned) - Depth-budget exhausted during `git fetch` deepening - REST call to listLastSuccessfulBuildOnBranch failed Adds `listLastSuccessfulBuildOnBranch` helper to shared/build.ts (reused by Stage 5 schedule contributor). Trust boundary: SYSTEM_ACCESSTOKEN is the bearer for both the REST lookup AND the git fetch deepening (passed via bearerEnv from shared/git.ts → spawned git child via GIT_CONFIG_* env vars). Bearer never reaches argv, never written to .git/config, never visible to the agent process. Bash allow-list grows by the seven read-only git commands (same as PR contributor).

From 7db94404a0c6d75623779ea2827b21a81b673925 Mon Sep 17 00:00:00 2001 From: James Devine Date: Sun, 14 Jun 2026 23:18:40 +0100 Subject: [PATCH 05/13] feat(exec-context): add workitem contributor (PR-linked, untrusted-prose boundary) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Stage 4 of the execution-context contributor build-out (plan.md). Adds the `workitem` contributor in PR-linked mode only (commit-scrape and parameter-driven modes are deferred follow-ups). Activates whenever the PR contributor activates and `workitem.enabled` is not false. **This is the first contributor that crosses an untrusted-prose boundary** — WI descriptions, acceptance criteria, repro steps, and comments are user-authored. The bundle wraps every prose body with `<<>>` sentinel markers via the new `shared/untrusted.ts::wrapAgentReadableUntrusted` helper, and the prompt fragment ONLY interpolates short structured fields (id / title / type / state). Long prose stays in files. Also introduces two new shared modules (used by this contributor today; expected to be reused by future prose contributors): - `shared/wit.ts` — work-item REST helpers (listPullRequestWorkItems, getWorkItem, getWorkItemComments, summariseRelations) - `shared/untrusted.ts` — sentinel wrapper + htmlToPlainText readability pass Artefacts staged under `aw-context/workitem/`: - `ids.txt` — newline-delimited linked WI ids - `/summary.json` — id/type/title/state/area/iter/assignee/tags - `/description.md` — sentinel-wrapped description - `/acceptance.md` — sentinel-wrapped acceptance criteria - `/repro.md` — sentinel-wrapped repro steps (Bug) - `/comments.json` — sentinel-wrapped per-comment - `/links.json` — relations summary - `/attachments.json` — attachment metadata (bytes NOT downloaded) - `truncated.txt` — overflow when linked count > max-items - `errors.txt` — per-id fetch failures - `error.txt` — total-failure (all fetches failed) Caps (configurable): - `workitem.max-items` (default 5) - `workitem.max-body-kb` (default 32 KB) Three failure-fragment modes (matching the plan): - No linked WIs → informational (not error) - Partial fetch failure → list per-id reasons; continue with successes - All fetches failed → tells agent to `report_incomplete` Trust boundary: SYSTEM_ACCESSTOKEN bearer mapped only into the prepare step's env block; never to the agent step's env. The sanctioned-displayName allow-list in compiler_tests.rs gains "Stage workitem execution context (aw-context/workitem/*)".

Adds the `schedule` contributor: stages "since last successful run on this branch" diff context for scheduled builds. Default-OFF (opt-in via `schedule.enabled: true`) AND requires `on.schedule` to be declared. Reuses shared/build.ts::listLastSuccessfulBuildOnBranch (Stage 2) + shared/git.ts deepening (Stage 0), so the bundle is a thin variation on exec-context-ci-push. Adds `previous-run-time` (ISO-8601, from Build.finishTime) as the only field unique to scheduled context. Runtime gate: `eq(variables['Build.Reason'], 'Schedule')`. Artefacts staged under `aw-context/schedule/`: - `current-sha` — Build.SourceVersion - `previous-run-sha` — SHA of the last successful scheduled run - `previous-run-time` — ISO-8601 finishTime of that run (when available) - `commits.txt` — `git log previous..current --oneline` - `changed-files.txt` — `git diff --name-status previous..current` - `error.txt` — present only on failure Trust boundary: identical to ci-push — SYSTEM_ACCESSTOKEN is the bearer for both REST + git fetch, mapped only into this step's env. Bash allow-list grows by the same seven read-only git commands. Wiring follows the established pattern: - New ScheduleContextContributor in exec_context/schedule.rs - Contributor::Schedule enum variant - schedule_contributor_will_activate helper (OR'd into aggregate flag) - EXEC_CONTEXT_SCHEDULE_PATH + exec_context_schedule_active on AdoScriptExtension; OR'd into install/download gate - ScheduleContextConfig on ExecutionContextConfig - New TS bundle scripts/ado-script/src/exec-context-schedule/ (with __tests__/index.test.ts; 7 vitest cases) Validation: - cargo build / cargo test (2046 Rust tests, 0 failures) / clippy clean - npm typecheck / test (369 TS tests) / build / smoke (6 tests) Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> --- .github/workflows/release.yml | 2 +- docs/execution-context.md | 23 +- scripts/ado-script/.gitignore | 1 + scripts/ado-script/package.json | 7 +- .../__tests__/index.test.ts | 170 ++++++++++ .../src/exec-context-schedule/index.ts | 311 ++++++++++++++++++ src/compile/extensions/ado_script.rs | 14 + .../extensions/exec_context/contributor.rs | 5 + src/compile/extensions/exec_context/mod.rs | 49 ++- .../extensions/exec_context/schedule.rs | 186 +++++++++++ src/compile/extensions/mod.rs | 5 +- src/compile/types.rs | 37 +++ 12 files changed, 787 insertions(+), 23 deletions(-) create mode 100644 scripts/ado-script/src/exec-context-schedule/__tests__/index.test.ts create mode 100644 scripts/ado-script/src/exec-context-schedule/index.ts create mode 100644 src/compile/extensions/exec_context/schedule.rs diff --git a/.github/workflows/release.yml b/.github/workflows/release.yml index a4a0c27c..b342cb5f 100644 --- a/.github/workflows/release.yml +++ b/.github/workflows/release.yml @@ -77,7 +77,7 @@ jobs: run: | set -euo pipefail cd scripts - zip -r ../ado-script.zip ado-script/gate.js ado-script/import.js ado-script/exec-context-pr.js ado-script/exec-context-pr-synth.js ado-script/exec-context-manual.js ado-script/exec-context-pipeline.js ado-script/exec-context-ci-push.js ado-script/exec-context-workitem.js + zip -r ../ado-script.zip ado-script/gate.js ado-script/import.js ado-script/exec-context-pr.js ado-script/exec-context-pr-synth.js ado-script/exec-context-manual.js ado-script/exec-context-pipeline.js ado-script/exec-context-ci-push.js ado-script/exec-context-workitem.js ado-script/exec-context-schedule.js - name: Upload release assets env: diff --git a/docs/execution-context.md b/docs/execution-context.md index c3ee6f6d..77933365 100644 --- a/docs/execution-context.md +++ b/docs/execution-context.md @@ -43,17 +43,14 @@ locally and `git` is added to its bash allow-list automatically. ## v1 contributors -| Contributor | Trigger | Output layout | -|-------------|-------------------------------|------------------------------| -| `pr` | `on.pr` | `aw-context/pr/*` | -| `manual` | any `parameters:` declared | `aw-context/manual/*` | -| `pipeline` | `on.pipeline` | `aw-context/pipeline/*` | -| `ci-push` | `ci-push.enabled: true` (CI/push reasons) | `aw-context/ci-push/*` | -| `workitem` | activates with `pr` (PR-linked mode) | `aw-context/workitem/*` | - -Future trigger contributors (schedule) plug in via the same internal -`ContextContributor` trait without breaking the agent-facing layout. -See plan.md for the full build-out roadmap. +| Contributor | Trigger | Output layout | +|-------------|----------------------------------------------------------|------------------------------| +| `pr` | `on.pr` | `aw-context/pr/*` | +| `manual` | any `parameters:` declared | `aw-context/manual/*` | +| `pipeline` | `on.pipeline` | `aw-context/pipeline/*` | +| `ci-push` | `ci-push.enabled: true` (CI/push reasons) | `aw-context/ci-push/*` | +| `workitem` | activates with `pr` (PR-linked mode) | `aw-context/workitem/*` | +| `schedule` | `on.schedule` declared AND `schedule.enabled: true` | `aw-context/schedule/*` | ## Front-matter surface @@ -76,6 +73,10 @@ execution-context: enabled: true # defaults to true when the pr contributor activates max-items: 5 # cap on linked WIs staged per build max-body-kb: 32 # cap per body field (description / acceptance / repro) + schedule: + enabled: false # OPT-IN (default OFF) — stages "since last successful + # run on this branch" diff context for scheduled builds + # (requires on.schedule) ``` All keys are optional.

From 7b80cac4927f3d6fec9ab8d1feae73c607c5ecf1 Mon Sep 17 00:00:00 2001 From: James Devine Date: Sun, 14 Jun 2026 23:49:57 +0100 Subject: [PATCH 07/13] feat(exec-context): add pr.checks extension (Build Validation triage) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Stage 6 of the execution-context contributor build-out (plan.md). Adds the `pr.checks` extension of the PR contributor: enumerates Build Validation runs on the PR and stages failing/succeeded arrays so a remediation agent can read failure logs and propose fixes. Default-OFF (opt-in via `pr.checks.enabled: true`) AND requires the PR contributor to activate. Adds `listBuildsForPullRequest` helper to shared/build.ts — queries the Build REST API by PR ref (`refs/pull//merge`). Artefacts staged under `aw-context/pr/checks/`: - `failing.json` — Build Validation runs with result != Succeeded (failed / partiallySucceeded / canceled) - `succeeded.json` — runs with result == Succeeded - `error.txt` — REST failure Trust boundary: SYSTEM_ACCESSTOKEN bearer for REST; same posture as the other PR contributors. The sanctioned-displayName allow-list in compiler_tests.rs gains "Stage PR-checks execution context (aw-context/pr/checks/*)". Implementation note: pr.checks is logically an extension of the PR contributor but is implemented as a separate Contributor variant (`Contributor::PrChecks`) for emit-cleanliness — the YAML gets a distinct step with its own runtime gate / displayName, and the `should_activate` chain (PR-contributor-enabled AND opt-in) gives precise control. Wiring: - New PrChecksContextContributor in exec_context/pr_checks.rs - Contributor::PrChecks enum variant - pr_checks_contributor_will_activate helper (tracks PR activation) - EXEC_CONTEXT_PR_CHECKS_PATH + exec_context_pr_checks_active on AdoScriptExtension; OR'd into install/download gate - PrChecksContextConfig nested in PrContextConfig (so the YAML surface stays `pr.checks.enabled` rather than a top-level key) - New TS bundle scripts/ado-script/src/exec-context-pr-checks/ (with __tests__/index.test.ts;

Adds the `repo` contributor: stages repository identity info (branch, SHA, last release tag, commits-since-tag) for any agent that wants `what repo am I in` framing without restating it in every markdown body. Default-OFF (opt-in via `repo.enabled: true`) to avoid prompt-clutter regression. Pure git, no REST, no bearer. Always-on capability (no Build.Reason gate) — the contributor's content is useful on any build reason. Artefacts staged under `aw-context/repo/`: - `branch` — Build.SourceBranchName (refs/heads/ stripped) - `sha` — Build.SourceVersion - `last-release-tag` — `git describe --tags --abbrev=0` (empty when no tags reachable) - `commits-since-tag.txt` — `git log ..HEAD --oneline` - `conventions.json` — presence flags + first 50 lines of each found of CODEOWNERS / CONTRIBUTING.md / .editorconfig / AGENTS.md. ONLY staged when `repo.conventions: true`. Trust boundary: pure git against local workspace. No SYSTEM_ACCESSTOKEN projected; no REST calls. Bash allow-list grows by 4 read-only git commands (git / git log / git rev-parse / git describe). Note on plan's overlap discussion: this iteration stages `sha` independently (does not demote pr/ci-push current-sha to symlinks). That refactor is deferred to a follow-up — the overlap is harmless (same value written to two paths); only sentinel cleanup at the aggregation layer would change the layout. Wiring follows the established pattern (new RepoContextContributor + Contributor::Repo + repo_contributor_will_activate helper + EXEC_CONTEXT_REPO_PATH + exec_context_repo_active on AdoScriptExtension + RepoContextConfig on ExecutionContextConfig).

From bc8594643f0531c5d2d85cf7fd638312ad5c01ac Mon Sep 17 00:00:00 2001 From: James Devine Date: Mon, 15 Jun 2026 00:06:50 +0100 Subject: [PATCH 09/13] =?UTF-8?q?chore(exec-context):=20Stage=208=20cleanu?= =?UTF-8?q?ps=20=E2=80=94=20stable=20ordering,=20dedup,=20trust-boundary?= =?UTF-8?q?=20parity?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Final stage of the execution-context contributor build-out (plan.md). Three cross-cutting cleanups now that all seven contributors are in tree: 1. **Stable prompt-fragment ordering.** `ExecContextExtension::contributors()` now returns contributors in a canonical order: repo → pr → pipeline → ci-push → schedule → workitem → pr.checks → manual This is the order prepare-step display names appear in the emitted YAML and (consequently) the order prompt fragments are appended to the agent prompt file. Rationale: identity context first (repo), then trigger-specific diff/build context, then linked-WI context (depends on PR context), then PR-checks (depends on workitem framing), then manual (free-form parameter snapshot). New test `prepare_step_ordering_is_stable_and_canonical` pins the order so a future contributor author cannot silently reorder. 2. **Bash-allow-list dedup audit.** Five contributors (pr, ci-push, schedule, repo) declare overlapping read-only `git` commands. `ExecContextExtension::bash_commands()` already deduped via `out.sort(); out.dedup();` — but there was no test trapping a future regression where a contributor's commands get added without dedup. New test `bash_commands_are_deduped_across_active_contributors` activates pr + ci-push + workitem + schedule + repo simultaneously and asserts the aggregate output has no duplicates. 3. **Trust-boundary test parity.** The sanctioned-displayName allow-list in `test_execution_context_pr_does_not_leak_system_accesstoken` now lists every contributor that legitimately maps `SYSTEM_ACCESSTOKEN` into its prepare step's env block: - Stage PR execution context (aw-context/pr/*) [pr] - Stage pipeline execution context (aw-context/pipeline/*) [pipeline] - Stage ci-push execution context (aw-context/ci-push/*) [ci-push] - Stage workitem execution context (aw-context/workitem/*) [workitem] - Stage schedule execution context (aw-context/schedule/*) [schedule] - Stage PR-checks execution context (aw-context/pr/checks/*) [pr.checks] - Execute safe outputs (Stage 3) [SafeOutputs] - Resolve synthetic PR context [synthPr] Each entry's comment explains why that step legitimately holds the bearer. Adding a new bearer-holding step to the codebase without adding it here will trip the test.

From c42bd4af0076813286b3efda4da0a581c836cd19 Mon Sep 17 00:00:00 2001 From: James Devine Date: Mon, 15 Jun 2026 10:38:30 +0100 Subject: [PATCH 10/13] chore(exec-context): address PR #1019 review nits MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Addresses the four suggestions from the automated Rust PR Reviewer (comment 4705527052) — all marked `minor / cosmetic`, none blocking the `Looks good to merge` summary. 1. **types.rs indentation.** The 6 new `ExecutionContextConfig` fields (manual, pipeline, ci_push, workitem, schedule, repo) and the `checks` field on `PrContextConfig` were over-indented by 4 spaces; the follow-on `impl` blocks for both structs (plus `PrChecksContextConfig`) had the same drift. Realigned to match the original `enabled` / `pr` field indent and module-level `impl` block indent. (cargo fmt would have caught this, but running it would also reformat unrelated files — manual fix only.) 2. **Redundant master-switch check** in `workitem_contributor_will_activate_with_cfg` (mod.rs). `pr_contributor_will_activate_with_cfg` already enforces `cfg.is_enabled()` internally, so the explicit re-check was dead code. Removed it and updated the comment to note why we don't re-check. 3. **MAINTENANCE comment mismatch** in `manual.rs::should_activate`. The old comment said the function must stay in lock-step with `manual_contributor_will_activate`, but the two deliberately diverge on the master-switch check (the predicate enforces it, the contributor delegates to the outer `declarations()` guard). Rewrote the comment to clarify that they must agree only on the contributor-local conditions (parameter list + per-contributor enabled flag) and to explain where the master switch is enforced. 4. **workitem bundle infra-failure path** now appends a failure fragment to the agent prompt before returning 1 from main(), matching the posture of every other contributor (manual, pipeline, ci-push, schedule, pr-checks, repo). Wrapped in a defensive try/catch since the same infra issue that broke mkdirSync may also break the prompt write — best-effort only, the underlying infra error takes precedence.

An adversarial WI author (anyone with WI write access can edit prose bodies) could embed the literal closing sentinel `:AW-UNTRUSTED>>>` in their description, forging a fake `end of untrusted region` that naive open/close pair scanning by Stage-2 detection would honour — allowing the attacker to make subsequent body content appear to lie outside the boundary. Fix: escape any literal sentinel-marker substrings in the body before wrapping. Both the prefix (`<<>>`) are substituted with their `-ESCAPED` variants. The escape is one-way (no round-trip back to the original text) — the body is read-only by the agent, so structural unambiguity matters more than byte fidelity. The forged-sentinel attempt is still visible in the staged file (as the `-ESCAPED` marker), giving Stage-2 detection a smuggling- attempt signal it can flag. Changes: - `scripts/ado-script/src/shared/untrusted.ts`: add `escapeSentinelMarkers` private helper + constants for the escaped variants; call it from `wrapAgentReadableUntrusted` before composing the wrapped output. - `scripts/ado-script/src/shared/__tests__/untrusted.test.ts`: add 3 new tests covering forged-close, forged-open, and repeated-marker injection. Update the existing "preserves body verbatim" test to clarify it only applies to non-sentinel content. - `scripts/ado-script/src/exec-context-workitem/index.ts`: extend the prompt fragment's UNTRUSTED CONTENT BOUNDARY note so the agent knows that an `-ESCAPED` substring inside a region indicates a neutralised smuggling attempt and warrants extra suspicion. - `docs/execution-context.md`: document the escape behaviour in the workitem contributor's "Untrusted-content boundary" section (both the mechanism and Stage-2 detection guidance for the `-ESCAPED` smuggling signal).

The outer `ExecContextExtension::declarations` loop checks `should_activate` before calling `prepare_step_typed`, so this wasn't a runtime bug — but a future test or tool that called `prepare_step_typed` directly (as the existing `hostile_parameter_name_rejected_by_contributor` test does in manual.rs) would silently get a live step instead of `None`. For the bearer-holding contributors (workitem in particular — fetches linked-WI prose via REST) this would mean a future test could accidentally emit a step with a live `SYSTEM_ACCESSTOKEN` into the YAML. Fix: add `if !self.should_activate(ctx) { return Ok(None); }` at the top of `prepare_step_typed` for all six contributors. This mirrors the manual.rs pattern uniformly. Bonus: the `_ctx` parameter is now actually used, so the parameter name drops the underscore prefix. New test `workitem::tests::prepare_step_returns_none_when_inactive` exercises the guard across all three inactive paths for the highest-consequence contributor (no on.pr, workitem.enabled: false, pr_contributor disabled).

This meant a direct call to `prepare_step_typed` with `config.enabled == Some(false)` AND non-empty parameters would still emit a live step, bypassing the explicit opt-out. The manual contributor carries no SYSTEM_ACCESSTOKEN so the security blast radius is low — but the pattern divergence undermines the defensive guarantee the comment promises and breaks consistency with the other five contributors (workitem, pipeline, ci_push, schedule, pr_checks, repo) which all use the `!should_activate(ctx)` form. Fix: replace the sub-check with `!self.should_activate(ctx)`, matching every other contributor. The `ctx` parameter loses its underscore prefix since it's now used. Comment rewritten to explain why the full predicate matters. New test `prepare_step_none_when_explicitly_disabled` pins the case the old guard missed: `enabled: Some(false)` plus non-empty parameters MUST return `Ok(None)`.
