* feat(middleware): add deterministic PII redaction for model-bound context
* fix(middleware): claim national IDs before cards, redact Command results, preserve ToolMessage fields
- Reorder detectors so checksum-gated national IDs run before the credit-card
detector; an 18-digit resident ID whose digit run also passes Luhn is no
longer mislabeled [CREDIT_CARD_n] (review finding, reproduced at 0a2a9d0)
- Redact ToolMessages carried in Command.update.messages, mirroring
ToolResultSanitizationMiddleware's dc_replace pattern
- Rebuild redacted ToolMessages via model_copy so artifact and
response_metadata survive
- Extend the numbered middleware chain in agents/middlewares/AGENTS.md
* fix(middleware): span one redactor per Command result; refresh stale AGENTS.md entry range
- Placeholder numbering now continues across every ToolMessage carried in a
single Command result (one _Redactor per _redact_result call) instead of
restarting per message
- The renumbered AGENTS.md chain still referenced entries 9-12 in the
ToolReceiptMiddleware entry; it now reads entries 10-13
* docs(agents): trim PiiRedactionMiddleware entry to fit the AGENTS.md chain budget
The main merge (fb36e0e) pushed the effective middlewares chain to 98341
bytes, 37 over the 98304 hard limit checked by agent-guidance (AG002).
Compress the entry while keeping the load-bearing facts: config gate, both
interception points incl. Command coverage, detector order rationale,
per-result numbering continuity, irreversibility, memory follow-up.
* fix(middleware): redact compaction input and reinjected summaries; harden detectors
Review round 3 on #5527:
- [P1] SummarizationMiddleware invokes its summary model directly from
before_model, outside PiiRedactionMiddleware's wrap_model_call, so raw
thread state reached the summary model and reinjected summaries carried
raw PII into model-bound context. Add a shared redact_text() seam: the
compaction prompt is redacted in _build_summary_prompt (app_config
already flows into the middleware) and DurableContextMiddleware redacts
summary_text at reinjection via a new pii_redaction_config knob wired
at both assembly sites.
- [P2] CUIT is 2+8+1 digits, not 2+10+1.
- [P2] Digit-anchored patterns use digit-aware lookarounds instead of
Unicode \b, which CJK characters defeat (身份证110105… / 手机号138…).
- [P2] The international-phone pattern no longer treats newlines as
separators, so a candidate cannot swallow the following numeric field
and then fail validation as a whole.
* fix(pii): redact title input and reserve summary placeholders
