Echo is a deterministic WARP runtime over witnessed causal history.\n\nThe durable territory is admitted causal history: transitions, frontiers, lane\nidentities, payload hashes, receipts, witnesses, checkpoints, suffixes, and\nretained boundary artifacts. Graphs, files, editor buffers, UI state, and debug\nviews are materialized readings emitted by observers or optics over that\nhistory. They may be cached, retained, transported, compared, or revealed, but\nthey are not the substrate ontology.\n\nPublic Echo surfaces should follow the WARP optic shape:\n\n```text\nexplicit causal basis/site\n+ bounded aperture\n+ law\n+ support, capability, budget, and evidence posture\n-> witnessed hologram\n```\n\nExternal callers propose explicit-base intents or observe through bounded\noptics. Echo admits, stages, pluralizes, conflicts, or obstructs those claims\nunder named law and emits receipts, reading envelopes, witnesses, or retained\nshells. Transport is witnessed suffix admission, not state sync. Application\nnouns belong in authored contracts and generated adapters, not in Echo core.\n\nKeep these sentences in view when changing architecture, docs, or APIs:\n\n```text\nThere is witnessed causal history.\nWARP optics chart it.\nHolograms witness those charts.\nMaterialized graphs are optional readings.\nContinuum is the protocol for lawful causal-history exchange.\n```\n\n## Git Rules\n\n- **NEVER** amend commits.\n- **NEVER** rebase or force-push.\n- **NEVER** push to `main` without explicit permission.\n- Always use standard commits and regular pushes.\n\n## Documentation & Planning Map\n\nDo not audit the repository by recursively walking the filesystem. Follow the authoritative manifests:\n\n### 1. The Entrance\n\n- **`README.md`**: Public front door, core value prop, and quick tour.\n- **`GUIDE.md`**: Orientation and productive-fast path.\n- **`docs/index.md`**: VitePress documentation map.\n\n### 2. The Bedrock\n\n- **`ARCHITECTURE.md`**: Authoritative structural reference (Hexagonal, Core, Memory).\n- **`VISION.md`**: Core tenets and the causal mission.\n- **`METHOD.md`**: Repo work doctrine (Backlog lanes, Cycle loop).\n\n### 3. The Direction\n\n- **`docs/BEARING.md`**: Current execution gravity and active tensions.\n- **`docs/design/ROADMAP.md`**: Broad strategic horizon and targets.\n- **`backlog/`**: The active source of truth for pending work.\n\n### 4. The Proof\n\n- **`CHANGELOG.md`**: Historical truth of merged behavior.\n- **`cargo xtask dind`**: Determinism convergence verification.\n\n## Context Recovery Protocol\n\nWhen starting a new session or recovering from context loss:\n\n1. **Read `docs/BEARING.md`** to find the current execution gravity.\n2. **Read `METHOD.md`** to understand the work doctrine.\n3. **Check `backlog/asap/`** for imminent work.\n4. **Check `git log -n 5` and `git status`** to verify the current branch state.\n\n## Executable Claim Protocol\n\nEngineering work must converge around executable evidence, not broad repository\ninterpretation. Before editing code, reduce the task to one executable claim:\n\n1. **Bound the Claim**: State the behavior, invariant, or artifact that must\n change.\n2. **Name the Witness**: Identify the smallest test, check, script, compile\n contract, golden vector, schema validation, or artifact inspection that can\n prove the claim.\n3. **Run the Witness When Feasible**: Prefer a failing witness before the fix.\n If the witness cannot execute because the repository is already broken,\n repair only the minimal compile/runtime blocker required to run it.\n4. **Do Not Expand from an Unblocker**: Do not turn a compile blocker into\n nearby architecture cleanup, docs cleanup, lint cleanup, migration sweep, or\n opportunistic refactor.\n5. **Green the Claim**: Implement the smallest fix, rerun the witness, and run\n only directly relevant surrounding checks unless broader validation is\n explicitly requested.\n6. **Stop on Green**: When the witness passes and the requested scope is\n satisfied, stop. Do not inspect more PR comments, audit more files, or clean\n unrelated residue without a new executable claim.\n\nIf unrelated failures remain, isolate them in the final report instead of\nabsorbing them into the task. Report files changed, symbols or behavior changed,\nwitness commands, pass/fail results, and intentional non-actions such as no\ncommit, no push, or no PR comment.\n\n## End of Turn Checklist\n\nAfter altering files:\n\n1. **Verify Truth**: Ensure documentation is updated if behavior or structure changed.\n2. **Log Debt**: Add follow-on backlog items to `bad-code/` or `cool-ideas/`.\n3. **Commit**: Use focused, conventional commit messages. Propose a draft before executing.\n4. **Validate**: Run `cargo check` and relevant tests.\n\n---\n\n**The goal is inevitability.

Below is the list of skills that can be used. Each entry includes a name, description, and file path so you can open the source for full instructions when using a specific skill.\n### Available skills\n- imagegen: Generate or edit raster images when the task benefits from AI-created bitmap visuals such as photos, illustrations, textures, sprites, mockups, or transparent-background cutouts. Use when Codex should create a brand-new image, transform an existing image, or derive visual variants from references, and the output should be a bitmap asset rather than repo-native code or vector. Do not use when the task is better handled by editing existing SVG/vector/code-native assets, extending an established icon or logo system, or building the visual directly in HTML/CSS/canvas. (file: /opt/codex/skills/.system/imagegen/SKILL.md)\n- openai-docs: Use when the user asks how to build with OpenAI products or APIs and needs up-to-date official documentation with citations, help choosing the latest model for a use case, or model upgrade and prompt-upgrade guidance; prioritize OpenAI docs MCP tools, use bundled references only as helper context, and restrict any fallback browsing to official OpenAI domains. (file: /opt/codex/skills/.system/openai-docs/SKILL.md)\n- plugin-creator: Create and scaffold plugin directories for Codex with a required `.codex-plugin/plugin.json`, optional plugin folders/files, and baseline placeholders you can edit before publishing or testing. Use when Codex needs to create a new local plugin, add optional plugin structure, or generate or update repo-root `.agents/plugins/marketplace.json` entries for plugin ordering and availability metadata. (file: /opt/codex/skills/.system/plugin-creator/SKILL.md)\n- skill-creator: Guide for creating effective skills. This skill should be used when users want to create a new skill (or update an existing skill) that extends Codex's capabilities with specialized knowledge, workflows, or tool integrations. (file: /opt/codex/skills/.system/skill-creator/SKILL.md)\n- skill-installer: Install Codex skills into $CODEX_HOME/skills from a curated list or a GitHub repo path. Use when a user asks to list installable skills, install a curated skill, or install a skill from another repo (including private repos). (file: /opt/codex/skills/.system/skill-installer/SKILL.md)\n### How to use skills\n- Discovery: The list above is the skills available in this session (name + description + file path). Skill bodies live on disk at the listed paths.\n- Trigger rules: If the user names a skill (with `$SkillName` or plain text) OR the task clearly matches a skill's description shown above, you must use that skill for that turn. Multiple mentions mean use them all. Do not carry skills across turns unless re-mentioned.\n- Missing/blocked: If a named skill isn't in the list or the path can't be read, say so briefly and continue with the best fallback.\n- How to use a skill (progressive disclosure):\n 1) After deciding to use a skill, open its `SKILL.md`. Read only enough to follow the workflow.\n 2) When `SKILL.md` references relative paths (e.g., `scripts/foo.py`), resolve them relative to the skill directory listed above first, and only consider other paths if needed.\n 3) If `SKILL.md` points to extra folders such as `references/`, load only the specific files needed for the request; don't bulk-load everything.\n 4) If `scripts/` exist, prefer running or patching them instead of retyping large code blocks.\n 5) If `assets/` or templates exist, reuse them instead of recreating from scratch.\n- Coordination and sequencing:\n - If multiple skills apply, choose the minimal set that covers the request and state the order you'll use them.\n - Announce which skill(s) you're using and why (one short line). If you skip an obvious skill, say why.\n- Context hygiene:\n - Keep context small: summarize long sections instead of pasting them; only load extra files when needed.\n - Avoid deep reference-chasing: prefer opening only files directly linked from `SKILL.md` unless you're blocked.\n - When variants exist (frameworks, providers, domains), pick only the relevant reference file(s) and note that choice.\n- Safety and fallback: If a skill can't be applied cleanly (missing files, unclear instructions), state the issue, pick the next-best approach, and continue.\n","\nFilesystem sandboxing defines which files can be read or written. `sandbox_mode` is `danger-full-access`: No filesystem sandboxing - all commands are permitted. Network access is enabled.\nApproval policy is currently never.

In long-lived runtimes this can prevent GC/eviction from reclaiming superseded blobs and cause unbounded retention growth; handle the `insert` return value and `unpin` the old hash (when it differs) before replacing it.\n\nUseful?

A semantic coordinate is supposed to name the question/evidence identity; silently changing the content hash for the same coordinate breaks auditability. Because `MemoryTier` pins are set-based, this also cannot be repaired safely with naive unpinning. | `Make RetainedBlobIndex::retain fail closed on same-coordinate/different-content writes. Add RetentionError::SemanticCoordinateConflict (or equivalent), make same-coordinate/same-content idempotent, and add tests for idempotent re-retain plus conflict rejection.` |\n| P2 | `crates/echo-cas/src/retention.rs:185-205` | `load_range(...)` returns budget errors before proving the semantic coordinate exists. | The docs say the semantic coordinate must match first, but code checks `len > max_bytes` before `self.load(...)`. A missing retained coordinate with an over-budget range reports `RangeExceedsBudget`, masking missing retention. | `Add a regression test proving missing semantic coordinates take precedence over range budget errors, then load the semantic coordinate before budget/range validation in load_range(...).` |\n| P2 | `docs/BEARING.md:77-90` | Current bearing contradicts this PR’s completed slice batch. | The “What Is Not Yet True” section still says contract-aware identities, semantic retention, and external proof fixtures are not yet present, while the same file later records those as completed slices. | `Update BEARING so the not-yet-true list reflects the branch: durable submission persistence, product API, reference host loop, broader replay/DIND proof, and release-grade quickstart remain; contract evidence/retention/generic external fixture should move out of stale missing-state wording.` |\n| P2 | `docs/design/v0.1.0-release-plan.md:100-130,341-350` | v0.1 feature/status tables still mark newly implemented capabilities as missing. | The release plan lists contract-aware receipts/readings, bounded reading identity, local retention, and external proof fixture as `Missing` after this PR implements local boundaries/proofs for them. | `Change these release-plan rows to Partial or Complete local proof as appropriate, with caveats for remaining durable persistence, obstruction taxonomy, full receipt identity, and release-grade external consumer proof.` |\n| P3 | `crates/warp-core/tests/installed_contract_intent_pipeline_tests.rs:954-963` | External proof fixture overclaims receipt retention by retaining only the receipt digest bytes. | `RetainedBlobRole::ContractReceipt` is populated with `&correlation.tick_receipt_digest`, not a serialized `TickReceipt`, receipt correlation record, or retained receipt envelope. This proves digest retention, not receipt material retention. | `Either retain actual receipt/correlation material under the ContractReceipt coordinate, or rename the fixture/docs to say receipt-digest evidence only and leave full receipt material retention as a follow-up.` |\n\nValidation run during review: `git diff --check origin/main...HEAD` and markdownlint over touched design/BEARING docs both passed.\n\n\n### 💡 Codex Review\n\nHere are some automated review suggestions for this pull request.\n\n**Reviewed commit:** `94018001f9`\n \n\n

\n**_{_{![P1 Badge](https://img.shields.io/badge/P1-orange?style=flat)}} Prevent same-coordinate retention from remapping content**\n\n`retain(...)` unconditionally inserts a new descriptor for an existing `SemanticBlobCoordinate`, so a second write with different bytes silently changes what that coordinate means. Because the old hash is already pinned and there is no reverse index/unpin path by coordinate, this also leaves unreachable pinned content behind. For evidence coordinates, this is a fail-open behavior that can hide caller bugs and break auditability; treat same-coordinate/different-hash as a typed conflict and keep same-coordinate/same-hash idempotent.\n\nUseful? React with 👍 / 👎.\n**_{_{![P2 Badge](https://img.shields.io/badge/P2-yellow?style=flat)}} Resolve semantic coordinate before budget checks in load_range**\n\n`load_range(...)` returns `RangeExceedsBudget` before attempting semantic lookup, so a missing coordinate with an over-budget `len` is misreported as a budget failure. That masks the authoritative retention error and conflicts with the function contract that semantic match is established first; perform `self.load(...)` before budget/range validation so missing retention is reported deterministically.\n\nUseful? React with 👍 / 👎.\n**_{_{![P3 Badge](https://img.shields.io/badge/P3-lightgrey?style=flat)}} Reconcile completed-slice claims with remaining-state section**\n\nThis newly added completion claim says contract-aware receipt/reading evidence is done, but the same document’s earlier “What Is Not Yet True” section still states those capabilities are not present. Keeping both statements makes BEARING internally inconsistent and can mislead release-tracking decisions; either remove/update the stale “not yet true” bullets or soften these completion claims.\n\nUseful?

\n**_{_{![P1 Badge](https://img.shields.io/badge/P1-orange?style=flat)}} Bump observation artifact version for new hash input fields**\n\nIncluding `contract` and `query_identity` in `ReadingEnvelope::to_abi()` changes the canonical `ObservationHashInput` bytes that `compute_artifact_hash` digests, but the observation identifiers remain `OBSERVATION_VERSION = 2` and `echo:observation-artifact:v2`. That means artifacts produced before and after this change can hash differently while claiming the same observation contract/version, which breaks cross-version comparability for retained artifact hashes and witnesses.\n\nUseful? React with 👍 / 👎.\n**_{_{![P1 Badge](https://img.shields.io/badge/P1-orange?style=flat)}} Bump ABI version after extending ReadingEnvelope response**\n\nThis change extends the public WASM ABI `ReadingEnvelope` shape with `contract` and `query_identity`, but `ABI_VERSION` is still 10. Clients that use `registry_info.abi_version` for negotiation cannot tell whether these fields are guaranteed to exist, so a new client can misclassify an older host as compatible (or vice versa) despite different response schemas.\n\nUseful?

`scheduler_status()` is the read-only scheduler"," metadata export, and `dispatch_intent(...)` is application intent ingress."," Accepted application ingress returns witnessed submission identity in addition"," to canonical intent identity."," The current ABI also publishes strand settlement comparison, planning,"," execution entrypoints, settlement basis evidence, overlap revalidation"," evidence, and read-side basis plus residual posture on observation artifacts.","- The engine-backed boundary uses logical clocks only:"," `WorldlineTick` is per-worldline append identity and `GlobalTick` is runtime"," cycle correlation metadata. No wall-clock time enters Echo internals.","- Public application dispatch rejects privileged scheduler control envelopes."," Trusted runtime control is kept on a separate Rust host/runtime-owner trait,"," not on the public browser application dispatch export.

A semantic coordinate is supposed to name the question/evidence identity; silently changing the content hash for the same coordinate breaks auditability. Because `MemoryTier` pins are set-based, this also cannot be repaired safely with naive unpinning. | `Make RetainedBlobIndex::retain fail closed on same-coordinate/different-content writes.

A missing retained coordinate with an over-budget range reports `RangeExceedsBudget`, masking missing retention. | `Add a regression test proving missing semantic coordinates take precedence over range budget errors, then load the semantic coordinate before budget/range validation in load_range(...).` |\n| P2 | `docs/BEARING.md:77-90` | Current bearing contradicts this PR’s completed slice batch. | The “What Is Not Yet True” section still says contract-aware identities, semantic retention, and external proof fixtures are not yet present, while the same file later records those as completed slices. | `Update BEARING so the not-yet-true list reflects the branch: durable submission persistence, product API, reference host loop, broader replay/DIND proof, and release-grade quickstart remain; contract evidence/retention/generic external fixture should move out of stale missing-state wording.` |\n| P2 | `docs/design/v0.1.0-release-plan.md:100-130,341-350` | v0.1 feature/status tables still mark newly implemented capabilities as missing. | The release plan lists contract-aware receipts/readings, bounded reading identity, local retention, and external proof fixture as `Missing` after this PR implements local boundaries/proofs for them. | `Change these release-plan rows to Partial or Complete local proof as appropriate, with caveats for remaining durable persistence, obstruction taxonomy, full receipt identity, and release-grade external consumer proof.` |\n| P3 | `crates/warp-core/tests/installed_contract_intent_pipeline_tests.rs:954-963` | External proof fixture overclaims receipt retention by retaining only the receipt digest bytes. | `RetainedBlobRole::ContractReceipt` is populated with `&correlation.tick_receipt_digest`, not a serialized `TickReceipt`, receipt correlation record, or retained receipt envelope. This proves digest retention, not receipt material retention. | `Either retain actual receipt/correlation material under the ContractReceipt coordinate, or rename the fixture/docs to say receipt-digest evidence only and leave full receipt material retention as a follow-up.` |\n\nValidation run during review: `git diff --check origin/main...HEAD` and markdownlint over touched design/BEARING docs both passed.\n","**_{_{![P2 Badge](https://img.shields.io/badge/P2-yellow?style=flat)}} Unpin replaced retention roots on coordinate overwrite**\n\nCalling `retain` with an existing `SemanticBlobCoordinate` overwrites the map entry but never unpins the previous `content_hash`, so repeated updates to the same coordinate accumulate pinned blobs that are no longer reachable via semantic lookup. In long-lived runtimes this can prevent GC/eviction from reclaiming superseded blobs and cause unbounded retention growth; handle the `insert` return value and `unpin` the old hash (when it differs) before replacing it.\n\nUseful?

fixes are pushed.\n\n| Issue | Severity | File(s) | Addressed by | Regression coverage | Outcome |\n|---|---:|---|---|---|---|\n| Retention accepted same semantic coordinate with different bytes | P1 | `crates/echo-cas/src/lib.rs` | `021dc59` | `same_semantic_coordinate_and_content_retain_idempotently`; `same_semantic_coordinate_with_different_content_is_rejected` | `RetainedBlobIndex::retain` now returns typed errors, is idempotent for identical content, and rejects semantic-coordinate/content drift. |\n| Range lookup checked budget before semantic coordinate existence | P2 | `crates/echo-cas/src/lib.rs` | `021dc59` | `missing_semantic_coordinate_takes_precedence_over_range_budget` | Missing semantic coordinate now reports `NotFound` before range-budget validation. |\n| External proof fixture retained only digest-shaped bytes | P2 | `crates/warp-core/tests/external_contract_proof_fixture.rs` | `021dc59` | `external_counter_contract_submit_tick_query_retain_and_replay_proof` | Fixture now retains deterministic receipt-correlation material with submission/ticket/receipt/package evidence. |\n| Observation artifact hash schema changed without artifact-version/domain bump | P1 | `crates/warp-core/src/observation.rs`, `docs/spec/SPEC-0009-wasm-abi-v3.md` | `c7aa63e` | `contract_query_identity_changes_when_plan_query_vars_or_basis_change` | Observation artifacts now use version 3 and `echo:observation-artifact:v3`, with a regression proving v2-domain hashes no longer match. |\n| Public WASM ABI response shape changed without ABI bump | P1 | `crates/echo-wasm-abi/src/kernel_port.rs`, `crates/warp-wasm/README.md` | `c7aa63e` | `kernel_port_abi_version_tracks_reading_envelope_contract_fields`; `registry_info_has_abi_version` | `ABI_VERSION` is now 11 and registry info reports the updated ABI. |\n| Optional `ReadingEnvelope` contract/query fields lacked legacy defaults | P2 | `crates/echo-wasm-abi/src/kernel_port.rs`, `crates/echo-wasm-abi/src/lib.rs` | `c7aa63e` | `test_optic_read_identity_round_trip` | Legacy CBOR reading envelopes with omitted optional fields decode to `None`. |\n| v0.1 retention status overclaimed complete retained refs/obstructions | P3 | `docs/design/v0.1.0-release-plan.md` | `c7aa63e` | `markdownlint-cli2`; `lint-dead-refs` | Release plan now splits implemented `RetainedBlobIndex` pieces from remaining retained refs, missing-retention obstruction, and durable recovery work.
