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. Every feature is defined by its tests.**\n\n",{"_408":707,"_389":390,"_410":396},{"_411":708,"_413":-5,"_41":-5,"_414":-5,"_94":709,"_90":416},[710,711],"developer",{"_45":713,"_90":698},{"_45":712,"_90":698},"\n## Skills\nA skill is a set of local instructions to follow that is stored in a `SKILL.md` file. 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).

\n\n\n_{Comment `@coderabbitai help` to get the list of available commands and usage tips.}\n\n\n**_{_{![P1 Badge](https://img.shields.io/badge/P1-orange?style=flat)}} Gate settlement of non-shared strands**\n\nThis fixture now creates an `AuthorOnly` strand, but the settlement tests below still expect `SettlementService::plan` to produce `ImportCandidate`, and `plan_with_policy` does not check `retention_posture` before appending imports. In debugger/author-only contexts this lets `SettlementService::settle` import a sealed strand suffix into the base worldline without any shared promotion/admission authority; settlement should reject/ignore non-`Shared` strands or these import fixtures should construct a `Shared` posture explicitly.\n\nUseful? React with 👍 / 👎.\n**_{_{![P2 Badge](https://img.shields.io/badge/P2-yellow?style=flat)}} Bind session posture derivation to session defaults**\n\nWhen callers use this session-default helper for fresh work, the arbitrary `posture_derivation` is accepted and passed straight into `RetentionPosture::new`; for example a `Shared` session default with a scope can be minted as `LegacyDurableAssumedShared`, and an `AuthorOnly` default can be minted as `DebuggerDefault`, even though neither came from migration or the debugger constructor. That makes the audit derivation on newly created strands untrustworthy; this helper should stamp `SessionDefault` itself and leave other derivations to their named constructors/migration paths.\n\nUseful? React with 👍 / 👎.\n**_{_{![P2 Badge](https://img.shields.io/badge/P2-yellow?style=flat)}} Propagate strand posture into retained settlement shells**\n\nNow that the strand has an authoritative `retention_posture`, settlement still has no way to use it: `build_braid_shell` receives only the fork basis/support pins and hard-codes both the member and shell posture to `CausalPosture::AuthorOnly`. When a legitimately `Shared` strand is settled, the retained braid-shell evidence will be stamped author-only instead of reflecting the strand's admitted posture, corrupting the posture recorded for settlement artifacts; pass the strand posture into shell construction instead of dropping it here.\n\nUseful?

\n| Severity | Source | File | Lines | Issue | Mitigation |\n|---|---|---:|---:|---|---|\n| P1 | PR/Self | `crates/warp-core/src/settlement.rs` | 682-833 | Settlement planning still imports non-`Shared` strand suffixes, so AuthorOnly debugger/session work can enter base shared history without admission. | Add a regression proving AuthorOnly settlement is rejected; require `Shared` posture before planning imports; make import-settlement fixtures explicitly `Shared`. |\n| P2 | PR/Self | `crates/warp-core/src/revelation.rs` | 383-389 | `SessionContext::retention_posture` accepts arbitrary `PostureDerivation`, allowing fresh session-created work to masquerade as debugger or legacy migration work. | Remove the derivation parameter; stamp `PostureDerivation::SessionDefault` inside the helper; keep debugger/migration derivations in named paths only. |\n| P2 | PR/Self | `crates/warp-core/src/settlement.rs` | 927-1376 | Settlement shell construction discards strand posture and hard-codes shell/member posture as `AuthorOnly`, corrupting retained shell posture for legitimately shared strands. | Thread the settled strand posture into `build_braid_shell`; assert shared settlement shells record `Shared`. |\n\n@codex please confirm these are the complete actionable issues for this pass.\n**_{_{![P1 Badge](https://img.shields.io/badge/P1-orange?style=flat)}} Require Shared posture before settlement imports**\n\nThis helper makes every settlement fixture `AuthorOnly`, but the existing import tests still exercise successful settlement; since `plan_with_policy` never checks `strand.retention_posture`, the same path will import debugger/session `AuthorOnly` suffixes into the base worldline as merge history. Please make the import fixtures explicitly `Shared` and reject non-`Shared` strands before planning import candidates.\n\nUseful? React with 👍 / 👎.\n**_{_{![P2 Badge](https://img.shields.io/badge/P2-yellow?style=flat)}} Stamp session posture derivation inside the helper**\n\nBecause `posture_derivation` is caller-controlled here, fresh work created through a normal session can be stamped with any derivation that validates for the default posture, e.g. `AuthorOnly + DebuggerDefault` or `Shared + ImportedManifest`, bypassing the named debugger/import paths that are supposed to be the only places those derivations originate. This helper should always use `PostureDerivation::SessionDefault` internally.\n\nUseful? React with 👍 / 👎.\n**_{_{![P2 Badge](https://img.shields.io/badge/P2-yellow?style=flat)}} Thread Shared strand posture into settlement shells**\n\nThis new path can create `Shared` strands, but settlement later builds braid shells without receiving `strand.retention_posture`; `build_braid_shell` still hard-codes both the member and shell posture to `AuthorOnly`. Any `Shared` strand that is settled will therefore be retained and queried as `AuthorOnly`, losing the admitted posture that this request preserved.\n\nUseful? React with 👍 / 👎.\n**_{_{![P2 Badge](https://img.shields.io/badge/P2-yellow?style=flat)}} Thread strand posture into plural artifacts**\n\nFor `Shared` strands made possible by this field, plural settlement still builds `PluralAlternativeDraft` in `settlement.rs` with `posture: CausalPosture::AuthorOnly`, and `append_plural_artifact` persists that posture into `ProvenanceEventKind::PluralArtifact`. A lawful shared plural alternative is therefore retained/indexed as `AuthorOnly` even if the braid shell posture is corrected, so posture-based readers miss it; pass `strand.retention_posture.causal_posture` through `plural_draft`.\n\nUseful? React with 👍 / 👎.\n**_{_{![P1 Badge](https://img.shields.io/badge/P1-orange?style=flat)}} Update downstream Strand test literals**\n\nAdding this required field leaves same-repo `Strand` literals in `crates/warp-wasm/src/warp_kernel.rs` tests without `retention_posture` (repo-wide search shows the setup literals around lines 1468 and 1529), so `cargo test -p warp-wasm` no longer compiles even though the warp-core-only slice passes. Please update those literals or route them through the new fork/posture helpers.\n\nUseful?

","**_{_{![P1 Badge](https://img.shields.io/badge/P1-orange?style=flat)}} Update downstream Strand test literals**\n\nAdding this required field leaves same-repo `Strand` literals in `crates/warp-wasm/src/warp_kernel.rs` tests without `retention_posture` (repo-wide search shows the setup literals around lines 1468 and 1529), so `cargo test -p warp-wasm` no longer compiles even though the warp-core-only slice passes. Please update those literals or route them through the new fork/posture helpers.\n\nUseful? React with 👍 / 👎.","crates/warp-core/src/strand.rs","RIGHT",148,"**_{_{![P2 Badge](https://img.shields.io/badge/P2-yellow?style=flat)}} Thread strand posture into plural artifacts**\n\nFor `Shared` strands made possible by this field, plural settlement still builds `PluralAlternativeDraft` in `settlement.rs` with `posture: CausalPosture::AuthorOnly`, and `append_plural_artifact` persists that posture into `ProvenanceEventKind::PluralArtifact`. A lawful shared plural alternative is therefore retained/indexed as `AuthorOnly` even if the braid shell posture is corrected, so posture-based readers miss it; pass `strand.retention_posture.causal_posture` through `plural_draft`.\n\nUseful? React with 👍 / 👎.","**_{_{![P2 Badge](https://img.shields.io/badge/P2-yellow?style=flat)}} Thread Shared strand posture into settlement shells**\n\nThis new path can create `Shared` strands, but settlement later builds braid shells without receiving `strand.retention_posture`; `build_braid_shell` still hard-codes both the member and shell posture to `AuthorOnly`. Any `Shared` strand that is settled will therefore be retained and queried as `AuthorOnly`, losing the admitted posture that this request preserved.\n\nUseful? React with 👍 / 👎.","crates/warp-core/src/coordinator.rs","**_{_{![P2 Badge](https://img.shields.io/badge/P2-yellow?style=flat)}} Stamp session posture derivation inside the helper**\n\nBecause `posture_derivation` is caller-controlled here, fresh work created through a normal session can be stamped with any derivation that validates for the default posture, e.g. `AuthorOnly + DebuggerDefault` or `Shared + ImportedManifest`, bypassing the named debugger/import paths that are supposed to be the only places those derivations originate. This helper should always use `PostureDerivation::SessionDefault` internally.\n\nUseful? React with 👍 / 👎.","**_{_{![P1 Badge](https://img.shields.io/badge/P1-orange?style=flat)}} Require Shared posture before settlement imports**\n\nThis helper makes every settlement fixture `AuthorOnly`, but the existing import tests still exercise successful settlement; since `plan_with_policy` never checks `strand.retention_posture`, the same path will import debugger/session `AuthorOnly` suffixes into the base worldline as merge history. Please make the import fixtures explicitly `Shared` and reject non-`Shared` strands before planning import candidates.\n\nUseful? React with 👍 / 👎.","| Severity | Source | File | Lines | Issue | Mitigation |\n|---|---|---:|---:|---|---|\n| P1 | PR/Self | `crates/warp-core/src/settlement.rs` | 682-833 | Settlement planning still imports non-`Shared` strand suffixes, so AuthorOnly debugger/session work can enter base shared history without admission. | Add a regression proving AuthorOnly settlement is rejected; require `Shared` posture before planning imports; make import-settlement fixtures explicitly `Shared`. |\n| P2 | PR/Self | `crates/warp-core/src/revelation.rs` | 383-389 | `SessionContext::retention_posture` accepts arbitrary `PostureDerivation`, allowing fresh session-created work to masquerade as debugger or legacy migration work. | Remove the derivation parameter; stamp `PostureDerivation::SessionDefault` inside the helper; keep debugger/migration derivations in named paths only. |\n| P2 | PR/Self | `crates/warp-core/src/settlement.rs` | 927-1376 | Settlement shell construction discards strand posture and hard-codes shell/member posture as `AuthorOnly`, corrupting retained shell posture for legitimately shared strands. | Thread the settled strand posture into `build_braid_shell`; assert shared settlement shells record `Shared`. |\n\n@codex please confirm these are the complete actionable issues for this pass.","**_{_{![P2 Badge](https://img.shields.io/badge/P2-yellow?style=flat)}} Propagate strand posture into retained settlement shells**\n\nNow that the strand has an authoritative `retention_posture`, settlement still has no way to use it: `build_braid_shell` receives only the fork basis/support pins and hard-codes both the member and shell posture to `CausalPosture::AuthorOnly`. When a legitimately `Shared` strand is settled, the retained braid-shell evidence will be stamped author-only instead of reflecting the strand's admitted posture, corrupting the posture recorded for settlement artifacts; pass the strand posture into shell construction instead of dropping it here.\n\nUseful? React with 👍 / 👎.","**_{_{![P2 Badge](https://img.shields.io/badge/P2-yellow?style=flat)}} Bind session posture derivation to session defaults**\n\nWhen callers use this session-default helper for fresh work, the arbitrary `posture_derivation` is accepted and passed straight into `RetentionPosture::new`; for example a `Shared` session default with a scope can be minted as `LegacyDurableAssumedShared`, and an `AuthorOnly` default can be minted as `DebuggerDefault`, even though neither came from migration or the debugger constructor. That makes the audit derivation on newly created strands untrustworthy; this helper should stamp `SessionDefault` itself and leave other derivations to their named constructors/migration paths.\n\nUseful? React with 👍 / 👎.","**_{_{![P1 Badge](https://img.shields.io/badge/P1-orange?style=flat)}} Gate settlement of non-shared strands**\n\nThis fixture now creates an `AuthorOnly` strand, but the settlement tests below still expect `SettlementService::plan` to produce `ImportCandidate`, and `plan_with_policy` does not check `retention_posture` before appending imports. In debugger/author-only contexts this lets `SettlementService::settle` import a sealed strand suffix into the base worldline without any shared promotion/admission authority; settlement should reject/ignore non-`Shared` strands or these import fixtures should construct a `Shared` posture explicitly.\n\nUseful?
