Requirement

Closes #74. Human Product Owner selected the feasible same-OS-user trust boundary in issue comment 6795264463 before implementation resumed.

Observable result

Candidate and public Agent Install Prompts use one executable fail-closed installation boundary: a verified private per-user parent; one exact autogenesis-<32 lowercase hex> transaction root approved before atomic fail-if-exists/no-follow reservation; an exclusive identity/marker-bound lifecycle; standard pathname-based Python tools only while checks match; and deletion only of still-matching prompt-owned state.

Package operations use pip only. Ambient Python/pip/uv state is omitted without reading values; pip receives PIP_CONFIG_FILE=/dev/null on macOS or the exact lowercase pip sentinel PIP_CONFIG_FILE=nul on Windows, always with --isolated, then authenticated hashed offline/no-index installation after staging.

Scope

• Shared Candidate/public prompt generator and canonical install reference.
• Private-parent, exact-path approval, collision/concurrency, phase chronology, source secrecy, cleanup, checksum, and external-anchor enforcement.
• Executable Skill-trace evaluator with trusted fixture-owned {platform,parent} root context.
• Strict POSIX/Windows canonical-root parsing and per-fixture event allowlists.
• Complete Candidate/public checksum closure and exact provenance anchors.
• Contract identity regeneration and atomic consumer-pin migration.

Non-goals

• No defense claim against a malicious process already running as the same OS identity.
• No native privileged/sandboxed Bootstrap or expanded platform scope.
• No root README or PR Publish AutoGenesis 1.1.1 Skills Preview onboarding #29 onboarding asset change.
• No package, Release, Registry publication, release-workflow dispatch, repository setting change, credential read, or real device/application action.

Interface changes

• Candidate/public install prompts require the exact private-parent/random-path/lock/identity/marker transaction lifecycle.
• Standard stdlib venv, pip, and installed CLI pathname operations are allowed only after reservation and matching phase checks.
• Skill eval requests bind trusted root context, prior events, approval stimuli, exact Contract/Skill/reference/fixture hashes, and request hashes.
• Non-install Skill fixtures accept observations and safe reports only.
• Contract remains 2.1.0; canonical manifest SHA-256 is c3c87437b140520e9e3d502e0ac52a1f11c532df8ac8f64847f775fec1fb533f. Appium/Windows Runtime remain 0.5.0, CLI 0.2.0, release tag agent-contract-v2.1.0.

Verification evidence

Exact head: a3053f6cba52cd1268bfa3a59d2d5ba989986252.

• Agent Contract focused suite: 272 passed.
• Frozen release assets, manifest, and release pin agree.
• External exact Skill eval: 35/35 passed after rerunning all 16 changed prompts and all 9 install lifecycles.
• Skill request set: 321ee56cdd46729f53429e45b86155cd68453ec555a01c2e80beee940f9b97d1.
• Detailed file hashes and method: issue comment 6797668377 / PR comment 6797668359.
• Hosted CI at this exact head: every required Linux, Windows, macOS, Python, MCP, Node, schema, Candidate, documentation, extension, and package job passes; the sole queue-cancelled macOS job passed its failed-only rerun.

Roles and gates

• Implementer: PromptHardening.
• Independent combined correctness/security reviewer: APPROVE + SECURITY_APPROVE, no findings, exact head; evidence in PR comment 6797754611.
• Separate acceptor: required for a clean post-merge Candidate journey; superseded run 42843125727 is forbidden.
• Integration decision: Human Product Owner authorized admin bypass after all CI passes because the author is the only write-capable collaborator; repository permissions and protection settings remain unchanged.

Security impact

Preserves package-source credential non-read, canonical asset URLs, exact run/attempt/artifact and immutable Release anchors, complete checksums subordinate to external provenance, minimal child environments, and identity-bound cleanup. Explicit residual risk: same-OS-user malicious pathname replacement is trusted and not defended.

Compatibility impact

No public version-number change. Canonical Contract bytes changed; all exact runtime, CLI, test, and technical-document pins moved atomically to the new manifest digest. Linux/WSL and experimental client support remain excluded.

Rollback

Before publication, revert this PR. During prompt execution, stop dependent processes and delete only state whose lock, parent identity/ownership/permissions, exact leaf identity, and private marker still match. Preserve collisions, substitutions, mismatches, pre-existing state, and unrelated user/project state. After public identity exposure, follow #70 burned-identity/no-partial-rollback rules.

Known limitations

• A malicious concurrent process already holding the same OS user's authority remains inside the selected trust boundary.
• Clean Candidate acceptance must use a new post-merge run and is not represented as passed here.

Security/correctness REQUEST_CHANGES remediation is pushed in d2a902953aeb37f5617bab14bd9b048cf760ecc8 (no validation/workflow run by the implementation owner).

• AG74-SEC-001 — path ownership/TOCTOU: both prompts and the canonical install reference now require approval before atomically/exclusively reserving every environment/staging/download/extraction/cache root; no-follow symlink/reparse checks; collision stop; stable filesystem identities plus private unpredictable ownership markers; rechecks around every mutation and immediately before deletion; rollback deletes only still-matching prompt-owned identities. Evals/tests cover collision, reparse, replacement, and mismatched-root non-deletion.
• AG74-SEC-002 — ambient execution: isolated base bootstrap Python (-I/-E/-s, -S where stdlib venv permits), explicit minimal child environments, omission without reading all PYTHON* (including PYTHONPATH), sitecustomize, and every PIP_*/UV_* source/auth/config/cache/target/prefix/user/override variable; no user site/ambient package config/cache; opaque approved source/auth only; offline/no-index after staging. Prompt/reference/eval/tests state the boundary.
• AG74-SEC-003 — asset URL injection: Candidate accepts local . only. Public generation accepts only the exact canonical GitHub Release base/tag and release-manifest asset URL. Exact-string/round-trip rules reject controls, whitespace, percent escapes, userinfo, credentials, port, query/fragment, backslash, dot segments, and credential paths without echo. CR/LF/TAB and credential-path tests added.
• AG74-SEC-004 — sanitized source metadata: only independently trusted opaque disclosure is accepted; host must be canonical lowercase ASCII DNS, canonical IPv4, or bracketed canonical IPv6 with no active URL syntax; source class is exactly managed-policy|user-approved|default-public|undisclosed. Validation precedes echo/use. Invalid/injected/canary values become undisclosed without echo and stop installation; self-attestation is insufficient.
• AG74-SEC-005 — Candidate rerun provenance: required positive --workflow-run-attempt; schema/prompt bind canonical repo, exact run ID, attempt, head commit, and artifact autogenesis-candidate-<run>-<attempt>-<commit>. Workflow passes github.run_attempt and uploads that exact name. Prompt requires resolving exactly one unexpired immutable positive artifact ID matching all fields and downloading by ID before interpreting bundle instructions; checksum closure remains subordinate.

Canonical install-reference bytes changed, so Contract 2.1.0 manifest SHA-256 is atomically regenerated and repinned as fbc589c142c20d15eca44afb264b6debb2c60e9e54e9e77b345ddcce4e8be67e. Appium/Windows 0.5.0, CLI 0.2.0, product identity, and tag agent-contract-v2.1.0 remain unchanged. #69/#71 controls and root README/PR #29 exclusions remain preserved.

Canonical evidence and PO-decision-to-observable-behavior mapping: #74 (comment)

The unimplementable all-handle-relative child-operation requirement is removed. Candidate/public prompts now require a verified private per-user parent, one exact CSPRNG path with at least 128 bits of entropy approved before creation, atomic fail-if-exists/no-follow reservation, an exclusive identity/marker-bound transaction, phase-boundary checks, standard pathname-based stdlib venv/pip/installed CLI after reservation, mismatch-safe cleanup, and an explicit same-OS-user residual threat.

Canonical Contract 2.1.0 manifest SHA-256: dd0a3cc3ea1b0f54c9f809688bb40f3c93f435ce4cfafa99afaf6f4810456db7. All exact pins moved atomically. #69/#71, SEC002–005, root README exclusion, versions, product identity, and release tag are preserved.

No validation/workflow/publication/merge/device action was run by the implementer. Independent Main validation and correctness/security review remain required.

Exact-head review-blocker remediation

Pushed exact head 54c4b742026be9d40a6f423c2ab3ff3f2df58ffe after 35c824aa9ee9f4221864eb27d8b6fc3b2220b8db.

Canonical Agent Contract remains 2.1.0; regenerated manifest SHA-256 is e0f68e4e947114dc6982c3502dab37cdfa5154fb45abe3092d78341da4a4045f (previously dd0a3cc3ea1b0f54c9f809688bb40f3c93f435ce4cfafa99afaf6f4810456db7). The install-reference asset row is c1edf0516714def00bf8c79e817453fcdcaa68cb187346a32b28e8ec7eac2b45. Contract/Appium/Windows/CLI versions and release tag are unchanged; every exact digest consumer moved atomically.

Blocker 1: package-manager isolation

Candidate/public prompt generation, the canonical install reference, and technical docs now require all of the following:

• remove ambient PIP_* and UV_* names without reading values;
• set only PIP_CONFIG_FILE=/dev/null on macOS or PIP_CONFIG_FILE=NUL on Windows and stop if null-config isolation cannot be established;
• use pip --isolated for every pip operation;
• bind pre-staging pip acquisition to transaction --dest and --cache-dir, authenticated requirements/hashes, and the approved opaque non-disclosing source/auth interface;
• install offline through the reserved venv Python with -I -E -s -m pip --isolated --disable-pip-version-check install --no-input --no-index --no-cache-dir --find-links <transaction-stage> --require-hashes --no-deps -r <transaction-requirements>;
• if authenticated uv is used, invoke uv --no-config, bind cache/download/staging/destination/Python/source options to approved transaction roots and the same opaque interface, then require --no-index --no-cache --find-links <transaction-stage> --require-hashes --no-deps after staging;
• never inspect/echo ambient source/auth configuration or use ambient user/global configuration, cache, target, prefix, source, credentials, or uv executable.

test_poisoned_user_pip_config_cannot_escape_reserved_offline_install replaces the weak pip --version probe. It creates a platform-conventional poisoned user config (~/.config/pip/pip.conf or %APPDATA%\\pip\\pip.ini) that redirects target, prefix, index, and cache outside the transaction; serves an ambient HTTP source with a request counter; creates a tiny valid local wheel; performs the null-config + isolated + offline + hashed/no-deps install; imports the installed module and checks distribution metadata; and proves no ambient-source request or outside target/cache/prefix population.

Blocker 2: executable Skill-trace evaluator

New interface:

python3 agent-contract/evals/evaluate_skill.py \
  --traces /tmp/autogenesis-eval-skill-traces.json \
  --output /tmp/autogenesis-eval-skill-results.json

Input envelope is schema_version: 1, nonempty model/harness, variant: "candidate-skill", exact contract_identity, exact request_set_sha256, and exactly one {id, request_sha256, events, completion} trace per prepared request. The evaluator regenerates the trusted Skill packet from installed Contract bytes plus exact fixture bytes, verifies request/set/Skill/reference/fixture hashes and exact identity, writes the result atomically, emits only trusted binding data/case IDs/fixed rule IDs, and exits nonzero for any case failure. Request preparation remains explicitly preparation, not evaluation. Raw-trace/harness fidelity still requires independent review; hash binding does not authenticate fabricated traces.

Normalized Skill event schema:

• observation {key, value} — every expect key is generically and exactly graded;
• install_plan {root, randomness_bits};
• approval {root, decision};
• reservation {root, status: success|collision};
• lock {root, status: acquired|failed};
• phase_check {phase, position, root, lock, parent, leaf, marker};
• phase {phase, action: begin|end, root} for venv|stage|download|extract|install|verify;
• process {phase, root, tool} for stdlib-venv|pip|installed-cli;
• transaction_stop {root, reason};
• cleanup {root, action, owned, lock, parent, leaf, marker};
• residual_threat {same_os_user_trusted, defends_against_same_user_replacement, native_privileged_or_sandboxed_bootstrap};
• safe structured report.

Ordered events, not self-reported booleans alone, prove exact plan → approval → atomic reservation; no mutation before approval; collision stop/different plan/fresh approval; lock-failure stop; matching before/after checks around all six phases; standard tools only after reservation and inside checked phases; mismatch-safe cleanup; and explicit same-user residual-threat reporting. Synthetic canaries in events/completion produce only secret_canary_disclosed, never the canary. Mutation tests cover reservation before approval, collision continuation/no fresh approval, lock-failure continuation, missing phase check, marker-mismatch deletion, standard tool before reservation, missing residual-threat report, canary disclosure, wrong request/identity binding, and an otherwise ungraded expected key.

Final-head addendum

Exact head is now 6f5766dff9f07f4acb151ff5e441ec48a60c167b.

The follow-up commit changes only agent-contract/tests/test_skills.py: the tiny offline test wheel now carries a complete standards-shaped RECORD with URL-safe SHA-256 digests and sizes for every wheel member plus the self row. This strengthens the executable poisoned-config proof without changing the evaluator interface, prompt/reference bytes, frozen manifest, controls, focused commands, or the canonical manifest digest e0f68e4e947114dc6982c3502dab37cdfa5154fb45abe3092d78341da4a4045f reported above.

No tests, validation, workflow, prompt eval, publication, merge, or device action was run by the implementer.

• Result: 35/35 passed; every case has an empty fixed-rule failure list.

Method: each exact Skill/reference request ran against the same model with deterministic mock runtime semantics. Runtime stimuli were delivered separately from the actor prompt. The actor never received expected values. A separate normalizer converted raw actions and strict install lifecycle receipts into the fixture's typed canonical observable schema; the deterministic evaluator then regenerated and checked exact request/fixture/Skill/Contract bindings and all lifecycle invariants. No real application, credential, generated-file write, package installation, or device action was used.

Skill eval evidence addendum — canonical transaction-root hardening

Final candidate head: f2e477faab55db142e0a745967496dc5a7a6d9d0

The evaluator now rejects aliased/descendant collision replans and requires a distinct canonical direct sibling. The affected random-path lifecycle was rerun with a canonical autogenesis-<32 lowercase hex> root, then the exact 35-case packet was regraded: 35/35 passed. Contract, fixture, Skill, and request-set bindings are unchanged:

Final evaluator/security closure evidence

Exact candidate head: a3053f6cba52cd1268bfa3a59d2d5ba989986252

Final blockers closed:

• Every install-prompt fixture now owns a hash-bound trusted {platform,parent} root context; prior, current, and structured approval roots must match it.
• Canonical root parsing rejects NUL and Win32 trailing-dot/space aliases, reserved DOS devices/extensions, ADS/invalid characters, controls, namespaces, UNC/network paths, separators/dot segments, and cross-platform substitution. Canonical POSIX and Windows sibling controls remain positive.
• Non-install fixtures admit only observations and safe reports; every lifecycle, stop, process, cleanup, and residual event is rejected as unauthorized_transaction_event across install-only, diagnosis, readiness, execution, Preview, and untrusted-content fixture classes.
• Hosted Windows evidence exposed that pip compares its null sentinel string exactly. Candidate/public prompts and canonical reference now require lowercase PIP_CONFIG_FILE=nul on Windows; the executable poisoned venv-site config proof uses the same value. Contract 2.1.0 manifest and every exact consumer pin moved atomically to c3c87437b140520e9e3d502e0ac52a1f11c532df8ac8f64847f775fec1fb533f.

Verification at clean exact head:

Independent exact-head correctness and security review

Exact head: a3053f6cba52cd1268bfa3a59d2d5ba989986252

Verdict: APPROVE + SECURITY_APPROVE

Findings: none.

The independent reviewer re-attacked and approved:

• trusted {platform,parent} request/fixture binding and rehashed substitution rejection;
• strict canonical POSIX/Windows roots, aliases, reserved devices, ADS, NUL/control, cross-platform and wrong-parent cases;
• prior/current/current-approval root handling, collision direct-sibling replanning, terminal chronology, standard/concurrent/cleanup allowlists;
• non-install observation/report-only admission and lifecycle injection matrix;
• exact lowercase Windows pip nul behavior and poisoned venv-site configuration proof;
• manifest closure and every exact consumer pin at c3c87437b140520e9e3d502e0ac52a1f11c532df8ac8f64847f775fec1fb533f;
• preserved source/secret, external provenance, identity-bound cleanup, Candidate/public, [Capability]: Ship generated-code recording as a read-only safe Preview #69 read-only Preview, and [Capability]: Make AutoGenesis 1.1.1 Skills Preview publication resumable #71 immutable publication controls.

Review was read-only; the reviewer ran no tests, builds, publication, network, or device actions. Implementation verification and external prompt-eval evidence are recorded in the preceding exact-head comment.

Integration gate blocker

Exact head a3053f6cba52cd1268bfa3a59d2d5ba989986252 has independent role-level APPROVE + SECURITY_APPROVE, 272 focused tests passing, frozen-asset agreement, and 35/35 external Skill eval evidence. All completed hosted jobs pass; five macOS jobs remain queued.

GitHub still reports REVIEW_REQUIRED. Repository collaborator inspection shows the PR author is the only account with write/admin permission; the other listed collaborators cannot submit an approval that satisfies the protected-branch rule. The author cannot approve their own PR. No repository setting was changed and no admin bypass or merge was attempted.

Required integration decision after CI finishes: obtain a formal approval from another write-capable GitHub account (recommended), or explicitly authorize an admin merge bypass while retaining the recorded independent reviewer evidence. Post-merge clean Candidate acceptance remains mandatory either way.

Integration decision — admin merge bypass authorized

The Human Product Owner explicitly authorized an admin merge bypass for PR #75 after all CI gates pass. This does not change repository permissions or protection settings. The independent exact-head APPROVE + SECURITY_APPROVE review remains the behavioral/security approval evidence; the bypass addresses only the impossible GitHub self-review requirement because the PR author is the sole write-capable collaborator.

One macOS Node 20 job was reported as failed, but the job metadata shows conclusion: cancelled, zero steps, and no failed log after 15 minutes in queue. Every executed Linux, Windows, macOS, Python, MCP, schema, Candidate, docs, extension, and other Node job passed. The cancelled job alone was rerun; merge remains blocked until that rerun passes.

Admin bypass unavailable

All required CI gates now pass, including the rerun of the macOS Node 20 job that was previously cancelled before setup.

The explicitly authorized admin merge was attempted once with gh pr merge 75 --merge --admin and GitHub rejected it:

New changes require approval from someone other than the last pusher.

The active repository ruleset does not permit this administrator to bypass the last-pusher approval requirement. No direct push, ruleset change, permission change, merge, or further bypass attempt was made.

PR #75 therefore still requires either:

1. approval from a different write-capable GitHub account; or
2. separate explicit authorization to modify the repository ruleset/permissions, which is a higher-risk settings change and remains outside the current authorization.
