GanyuanRan/Aegis v2.5.0 on GitHub

v2.5.0 (2026-07-19)

Promoted project-level CONTEXT.md from an optional glossary into a stable,
bounded semantic context surface for canonical terms, aliases, distinctions,
and authority references.
Split context handling into cheap passive consumption and explicitly owned
active modeling, so ordinary work can reuse established language without
loading a separate modeling workflow.
Added evidence grades and fact-versus-decision authority rules: agents may
record high-confidence resolved facts directly, while unresolved product or
architecture decisions still require clarification.
Added a compact root context baseline for Aegis Method Pack, Host Adapter,
Runtime Core, and runtime-ready artifact without moving runtime authority
into the method pack.

Integrated semantic context as a thin input to planning, brainstorming,
debugging, review, continuation, and verification workflows while retaining
establishing-project-context as the single active-modeling owner.
Required byte-stable no-op behavior, lazy first creation, pre-write readback,
concurrent-edit protection, safe path resolution, legacy table readability,
and instruction-like content isolation.
Added trigger-health coverage that distinguishes passive reuse, resolved
semantic changes, and tiny-task false positives.
Documented stable semantic prefixes as a cache opportunity rather than a
provider-independent cache-hit or token-savings guarantee.

Added a 15-case deterministic semantic-context matrix and wired it into the
Layer 1 release gate.
Added an opt-in, temporary-project live runner with checkout/installed source
modes, installed-skill fingerprint protection, and no host-configuration
mutation.
Extended Codex smoke-log parsing to recognize direct POSIX sed skill reads
while retaining the existing PowerShell coverage and transcript-noise guards.
Representative Codex checkout runs passed first resolved-fact creation,
byte-stable no-op handling, and passive context consumption. The installed
old-skill fingerprint was rejected as stale by design; Claude CLI live
coverage remains environment-bound and was not claimed.
Fresh bash tests/e2e/run-all.sh --full --host-profile fast verification
passed all four suites. Layer 1 passed 40/40, including representative
Codex automatic and explicit skill-loading smoke, OpenCode base coverage,
and Codex plugin-sync regression; Layer 2 and Layer 3 each passed 6/6.

Bumped all declared package and host manifest versions from 2.4.7 to
2.5.0.
This release remains Aegis Method Pack (runtime-ready), preserves
multi-host plugin-installable distribution, and does not add authoritative
GateDecision, PolicySnapshot, or completion authority.
