In `@docs/edge/en/observability/capsule-emit.mdx`:
- Line 93: Update the observability tables in
docs/edge/en/observability/capsule-emit.mdx (line 93) and
docs/edge/ar/observability/capsule-emit.mdx (line 93) to document effect.status
and verdict as separate fields: effect.status supports planned, confirmed, and
failed, while verdict supports executed and errored.
- Line 31: Pin the capsule-emit installation commands in
docs/edge/en/observability/capsule-emit.mdx (lines 31, 68-69, and 72) and
docs/edge/ar/observability/capsule-emit.mdx (lines 31, 68-69, and 72) to
capsule-emit[crewai]==0.4.0 so they match the documented sample output; update
both language versions consistently.
- Around line 14-15: Update the capsule verification descriptions to distinguish
responsibilities: verify() performs structural, content-addressing, and
parent-ID format checks without a store, while verify_store(...) additionally
validates parent existence and concurrent supersedes relationships. Apply the
corresponding wording updates at docs/edge/en/observability/capsule-emit.mdx
lines 14–15 and 22, and docs/edge/ar/observability/capsule-emit.mdx lines 14–15
and 22.
In `@docs/edge/ko/observability/capsule-emit.mdx`:
- Line 21: Update the digest-only privacy statements at the referenced
documentation points to clarify that SHA-256 digest recording does not provide
confidentiality. Advise users not to commit low-entropy sensitive values
directly, or document and recommend an approved blinding mechanism.
- Line 31: Update both capsule-emit installation commands in this page to pin
the dependency to the documented version 0.4.0, including the optional crewai
extra, so the examples match the stated output and anchoring behavior.
- Around line 92-93: Update both localized observability tables so the
event-state mappings match CapsuleEventListener: use effect.status for planned,
confirmed, and failed, and use verdict for executed and errored. Ensure ledger
query guidance in both the Korean and Brazilian Portuguese tables references the
correct field.
- Around line 14-22: Update the verification descriptions in both localized
pages to distinguish record-local checks from ledger-level checks: document
agent_action_capsule.verify() as validating only structure, content addressing,
and local chain links, and verify_store(...) as additionally validating parent
existence and concurrent supersedes consistency. Ensure the text does not imply
that isolated verify() proves a complete chain.
In `@docs/edge/pt-BR/observability/capsule-emit.mdx`:
- Line 21: Update the “Privacidade somente por digest” documentation to qualify
that SHA-256 digests prevent only direct disclosure, not inference of
low-entropy values through guess-and-hash comparisons. Advise users not to
commit low-entropy sensitive inputs, or reference an approved blinding mechanism
if one exists.
- Line 31: Update both capsule-emit installation commands in the page to pin the
CrewAI extra to version 0.4.0, preserving the existing examples and receipt
flow.

| - **Offline, `verify()`** checks structure, content addressing (every digest recomputes from the record's own contents), and chain consistency — no service, no credentials. | ||
| - **Tamper-evidence toward an outside party** comes from the anchoring step: capsule digests are registered with a SCITT transparency log, and the log's receipt is what makes after-the-fact alteration evident to someone outside your environment. The quickstart runs this step against a local stub service so the demo stays hermetic; production anchoring points at a real log. |

Assign chain checks to verify_store(...).
When called without a store, verify() checks the capsule and parent ID format but cannot check parent existence. Only verify_store(...) also checks concurrent supersedes relationships. Update the English and Arabic descriptions at lines 14–15 and 22.

Separate record-level and store-level verification in both localized pages. The no-store form of agent_action_capsule.verify() does not check parent existence; verify_store(...) supplies the ledger for parent-existence and concurrent-supersedes checks. Update lines 14 and 22 in both pages so verify() covers only record-local checks and verify_store(...) covers ledger-level consistency. Otherwise an isolated verify() result may be treated as proof of a complete chain even when a parent is absent.

PyPI capsule-emit versions 0.4.0 0.5.0 0.7.0 documentation legacy anchor channel default checkpoint witness anchor_wait
💡 Result:
The package capsule-emit is a producer library for Agent Action Capsules, a SCITT-based statement profile [1][2]. Its features related to anchoring, checkpointing, and witnessing have evolved through its version history [2][3]. Key concepts and their implementation: - Anchoring: Anchoring is on by default [4][2]. It involves submitting a capsule's SHA-256 digest (capsule_id) to a SCITT transparency log asynchronously and non-blockingly [4][5]. This process is optional and can be disabled via emit(..., anchor=False) or configured with custom URLs [5]. - Checkpointing: Introduced prominently in version 0.5.0, checkpointing is per-stream [3]. It uses a Merkle Mountain Range (MMR) index over the local ledger [2][3]. Every ~100 records (by default, controlled by capsule_emit.witness.DEFAULT_CADENCE_ENTRIES), the system builds and registers a signed checkpoint summary to an independent witness [3]. - Witnessing: Checkpointing is considered a form of witnessing that is on by default [6]. It can be disabled using the parameter emit(..., witness=False) or the environment variable CAPSULE_WITNESS=off [6]. - Legacy/Channel/Anchor_wait: While not explicitly defined as core singular flags in the provided documentation, these terms relate to the configuration of the anchoring and witnessing lifecycle. For example, anchor_url allows configuring the log service, and anchoring behavior is managed as part of the emit function's orchestration [5]. Version milestones: - 0.4.0: Introduced refined documentation, including guides on the public log, adapters (for MCP, LangChain, etc.), and the checkpointing module [2]. - 0.5.0: Established checkpointing as a default feature, providing signed summaries of the stream to independent witnesses [3]. - 0.7.0 (Contextual): While specific documentation for 0.7.0 was not explicitly detailed in the search results, the project continues to track standard draft specifications (e.g., draft-mih-scitt-agent-action-capsule) and maintains backward compatibility for capsule verification [2][3]. Documentation for these features is managed within the official repository's docs folder, such as docs/checkpoint.md and docs/the-public-log-explained.md [2][3][5].

Pin capsule-emit to the version used by this page.
Both install commands request the latest release, while the sample output and behavior table target capsule-emit 0.4.0. Version 0.5.0 introduced default checkpointing and independent witnessing, so an unpinned install can differ from the documented anchoring and anchor_wait flow. Pin both commands to capsule-emit==0.4.0, or update the affected examples for a tested release.

Separate effect.status from verdict in both localized tables.
CapsuleEventListener stores planned, confirmed, and failed in effect.status. It stores executed and errored in verdict. Update the Korean and Brazilian Portuguese tables so ledger queries use the correct fields.

capsule-emit PyPI 0.4.0 0.5.0 0.7.0 anchor_wait SCITT checkpoint witness documentation
💡 Result:
As of September 3, 2026, the PyPI package capsule-emit has not reached versions 0.4.0, 0.5.0, or 0.7.0. The most recent version on PyPI is 0.3.2 [1][2]. capsule-emit is a producer library for the Agent Action Capsule, which acts as a statement profile for SCITT (Supply Chain Levels for Software Artifacts/IETF SCITT) [1][3][4]. The library provides an emit function that generates content-addressed, digest-committed capsules [1][3]. By default, it performs an asynchronous, non-blocking submission of the capsule's digest to an RFC 9162-compliant SCITT transparency log for anchoring [1][3]. There is no technical feature or documented concept named "anchor_wait" associated with the capsule-emit library or the SCITT checkpoint/witness ecosystem [1][3]. In the context of SCITT, transparency services use "witnesses" and "checkpoints" to provide cryptographic proof of inclusion in a log, but "anchor_wait" is not a standard term or implementation detail in these specifications or the capsule-emit codebase [1][5][4]. The term "anchor_wait" or similar patterns often appear in unrelated technical contexts, such as Chromium browser test utilities (e.g., AccessibilityNotificationWaiter) [6][7] or unrelated personal accounts [8]. It is not a feature of the SCITT-based agent action verification workflow [1][5][4].

site:github.com/action-state-group/capsule-emit OR site:pypi.org/project/capsule-emit "anchor_wait" "0.4.0"
💡 Result:
The term anchor_wait is not a standalone tool or library, but rather refers to the default anchoring behavior in early versions of the capsule-emit library, a tool used to generate Agent Action Capsules [1][2][3]. In capsule-emit version 0.4.0, anchoring is enabled by default [1][2]. When the emit function is called, the digest of the capsule is submitted asynchronously and in a non-blocking manner to an RFC 9162 SCITT (Supply Chain Integrity, Transparency, and Trust) transparency log [1][2]. This process ensures that the capsule's existence is recorded and can be independently verified [1][3]. Key characteristics of this mechanism include: - What is logged: Only a SHA-256 digest is submitted to the log; the actual payloads remain on the user's machine [1][2]. - Default Behavior: The library uses a free hosted log (at https://anchor.agentactioncapsule.org/v1/digest) by default, though users can self-host their own log service (capsule-anchor) or configure a different URL using the AAC_ANCHOR_URL environment variable [1][4]. - Flexibility: Anchoring is optional and can be disabled by passing anchor=False to the emit function, which seals the capsule locally without network interaction [1][4]. Note that in later versions, such as 0.6.1, this per-capsule anchoring was transitioned to a legacy, non-default feature in favor of a checkpoint/witness stream as the primary default egress path [5].

capsule-emit 0.4.0 PyPI release 0.7.0 PyPI anchor_wait
💡 Result:
The package capsule-emit is a Python library used to produce Agent Action Capsules, which are verifiable, content-addressed statements [1][2]. It is maintained by the Action State Group [1]. As of September 3, 2026, version 0.4.0 of capsule-emit is a published release [1]. There is no official release of capsule-emit version 0.7.0 [3][4]. Regarding the term "anchor_wait," there is no widely recognized package by that specific name on PyPI. While "anchor" and "wait" are common terms in technical software, existing packages include "anchor-runtime" (a separate SDK) [5], "anchorai" (an AI-related tool) [6], and "nano-wait" or "urlwait" (execution and connection waiting utilities) [7][8]. It is likely that "anchor_wait" refers to either a confusion of these terms or a custom, non-public implementation related to the anchoring functionality (where capsule-emit submits data to a transparency log) [2][3]. The capsule-emit library specifically uses an anchoring mechanism where the digest of a capsule is submitted to a SCITT transparency log to ensure independent verifiability [2][3]. The official documentation emphasizes that the library is in an alpha state and remains under active development [2].

Adds a short observability-integrations page for capsule-emit: its
CapsuleEventListenerattaches via CrewAI's standard event bus and records each step as a signed, content-addressed Agent Action Capsule — a planned/executed/failed chain per step that a third party can verify offline, complementary to tracing. No core changes; same shape as the other observability vendor pages already listed.Every code block was executed against the released package before submission.
