Qi Ke f2fba4f9a1 fix(anthropic): auto-detect Bedrock model IDs in normalize_model_name (#12295) 
Bedrock model IDs use dots as namespace separators (anthropic.claude-opus-4-7,
us.anthropic.claude-sonnet-4-5-v1:0), not version separators.
normalize_model_name() was unconditionally converting all dots to hyphens,
producing invalid IDs that Bedrock rejects with HTTP 400/404.

This affected both the main agent loop (partially mitigated by
_anthropic_preserve_dots in run_agent.py) and all auxiliary client calls
(compression, session_search, vision, etc.) which go through
_AnthropicCompletionsAdapter and never pass preserve_dots=True.

Fix: add _is_bedrock_model_id() to detect Bedrock namespace prefixes
(anthropic., us., eu., ap., jp., global.) and skip dot-to-hyphen
conversion for these IDs regardless of the preserve_dots flag.

Brian D. EvansandClaude Opus 4.6 1cf1016e72 fix(run_agent): preserve dotted Bedrock inference-profile model IDs (#11976) 
Bedrock rejects ``global-anthropic-claude-opus-4-7`` with ``HTTP 400:
The provided model identifier is invalid`` because its inference
profile IDs embed structural dots
(``global.anthropic.claude-opus-4-7``) that ``normalize_model_name``
was converting to hyphens.  ``AIAgent._anthropic_preserve_dots`` did
not include ``bedrock`` in its provider allowlist, so every Claude-on-
Bedrock request through the AnthropicBedrock SDK path shipped with
the mangled model ID and failed.

Root cause
----------
``run_agent.py:_anthropic_preserve_dots`` (previously line 6589)
controls whether ``agent.anthropic_adapter.normalize_model_name``
converts dots to hyphens.  The function listed Alibaba, MiniMax,
OpenCode Go/Zen and ZAI but not Bedrock, so when a user set
``provider: bedrock`` with a dotted inference-profile model the flag
returned False and ``normalize_model_name`` mangled every dot in the
ID.  All four call sites in run_agent.py
(``build_anthropic_kwargs`` + three fallback / review / summary paths
at lines 6707, 7343, 8408, 8440) read from this same helper.

The bug shape matches #5211 for opencode-go, which was fixed in commit
f77be22c by extending this same allowlist.

Fix
---
* Add ``"bedrock"`` to the provider allowlist.
* Add ``"bedrock-runtime."`` to the base-URL heuristic as
  defense-in-depth, so a custom-provider-shaped config with
  ``base_url: https://bedrock-runtime.<region>.amazonaws.com`` also
  takes the preserve-dots path even if ``provider`` isn't explicitly
  set to ``"bedrock"``.  This mirrors how the code downstream at
  run_agent.py:759 already treats either signal as "this is Bedrock".

Bedrock model ID shapes covered
-------------------------------
| Shape | Preserved |
| --- | --- |
| ``global.anthropic.claude-opus-4-7`` (reporter's exact ID) | ✓ |
| ``us.anthropic.claude-sonnet-4-5-20250929-v1:0`` | ✓ |
| ``apac.anthropic.claude-haiku-4-5`` | ✓ |
| ``anthropic.claude-3-5-sonnet-20241022-v2:0`` (foundation) | ✓ |
| ``eu.anthropic.claude-3-5-sonnet`` (regional inference profile) | ✓ |

Non-Claude Bedrock models (Nova, Llama, DeepSeek) take the
``bedrock_converse`` / boto3 path which does not call
``normalize_model_name``, so they were never affected by this bug
and remain unaffected by the fix.

Narrow scope — explicitly not changed
-------------------------------------
* ``bedrock_converse`` path (non-Claude Bedrock models) — already
  correct; no ``normalize_model_name`` in that pipeline.
* Provider aliases (``aws``, ``aws-bedrock``, ``amazon``,
  ``amazon-bedrock``) — if a user bypasses the alias-normalization
  pipeline and passes ``provider="aws"`` directly, the base-URL
  heuristic still catches it because Bedrock always uses a
  ``bedrock-runtime.`` endpoint.  Adding the aliases themselves to the
  provider set is cheap but would be scope creep for this fix.
* No other places in ``agent/anthropic_adapter.py`` mangle dots, so
  the fix is confined to ``_anthropic_preserve_dots``.

Regression coverage
-------------------
``tests/agent/test_bedrock_integration.py`` gains three new classes:

* ``TestBedrockPreserveDotsFlag`` (5 tests): flag returns True for
  ``provider="bedrock"`` and for Bedrock runtime URLs (us-east-1 and
  ap-northeast-2 — the reporter's region); returns False for non-
  Bedrock AWS URLs like ``s3.us-east-1.amazonaws.com``; canary that
  Anthropic-native still returns False.
* ``TestBedrockModelNameNormalization`` (5 tests): every documented
  Bedrock model-ID shape survives ``normalize_model_name`` with the
  flag on; inverse canary pins that ``preserve_dots=False`` still
  mangles (so a future refactor can't decouple the flag from its
  effect).
* ``TestBedrockBuildAnthropicKwargsEndToEnd`` (2 tests): integration
  through ``build_anthropic_kwargs`` shows the reporter's exact model
  ID ends up unmangled in the outgoing kwargs.

Three of the new flag tests fail on unpatched ``origin/main`` with
``assert False is True`` (preserve-dots returning False for Bedrock),
confirming the regression is caught.

Validation
----------
``source venv/bin/activate && python -m pytest
tests/agent/test_bedrock_integration.py tests/agent/test_minimax_provider.py
-q`` -> 84 passed (40 new bedrock tests + 44 pre-existing, including
the minimax canaries that pin the pattern this fix mirrors).

CI-aligned broad suite: 12827 passed, 39 skipped, 19 pre-existing
baseline failures (all reproduce on clean ``origin/main``; none in
the touched code path).

JiaDe WU 0cb8c51fa5 feat: native AWS Bedrock provider via Converse API 
Salvaged from PR #7920 by JiaDe-Wu — cherry-picked Bedrock-specific
additions onto current main, skipping stale-branch reverts (293 commits
behind).

Dual-path architecture:
  - Claude models → AnthropicBedrock SDK (prompt caching, thinking budgets)
  - Non-Claude models → Converse API via boto3 (Nova, DeepSeek, Llama, Mistral)

Includes:
  - Core adapter (agent/bedrock_adapter.py, 1098 lines)
  - Full provider registration (auth, models, providers, config, runtime, main)
  - IAM credential chain + Bedrock API Key auth modes
  - Dynamic model discovery via ListFoundationModels + ListInferenceProfiles
  - Streaming with delta callbacks, error classification, guardrails
  - hermes doctor + hermes auth integration
  - /usage pricing for 7 Bedrock models
  - 130 automated tests (79 unit + 28 integration + follow-up fixes)
  - Documentation (website/docs/guides/aws-bedrock.md)
  - boto3 optional dependency (pip install hermes-agent[bedrock])
