Added src/forge/models/model_tier_estimator.py implementing estimate_tier(summary, description="") -> TierEstimate as a pure, deterministic, side-effect-free heuristic per Section 10.5 (NFR-005). - description defaults to "" so single-argument RED tests pass while the spec signature estimate_tier(summary, description) is honoured. - Keyword/signal sets (CRITICAL/COMPLEXITY/HEAVY/LIGHT_KEYWORDS) and the LONG_DESCRIPTION_CHAR_THRESHOLD are module-level tunable constants (NFR-002, BR-010). - Algorithm order: baseline STANDARD + baseline reason (empty/whitespace records the empty-text reason); critical -> CRITICAL; complexity/heavy signals or long description -> HEAVY; small/isolated/UI-copy + short description -> LIGHT with explicit demotion reasons; reasons always non-empty. Matching is case-insensitive over summary + "\n" + description with sorted keyword hits for determinism (TS-019). - Does not import model_policy (behavioural isolation), mirroring model_tier.py.

JiraClient Detailed description: - Added four async tier methods to JiraClient (src/forge/integrations/jira/client.py): - apply_tier_label: single PUT /issue/{key} with combined update.labels add/remove ops via core enforce_single_tier, guaranteeing exactly one forge:model-tier:* label; coerces ModelTier(tier) first so out-of-set values raise without mutating labels (FR-007/BR-004). - post_tier_comment: renders body via load_prompt(model-tier-comment) and posts through add_comment; body has the verbatim marker paragraph, a Why section with reasons, a demotion basis for LIGHT, and override instructions referencing TIER_LABEL_PREFIX (FN-003/9.6/BR-012/NFR-006). - get_latest_tier_marker: reverse-order scan over get_comments reusing parse_latest_tier_marker; latest-wins, invalid markers ignored (FN-006/BR-008). - resolve_and_maybe_assign_tier: Task-only guard (BR-006) plus assign/overwrite/no-op ownership branches via resolve_tier_ownership and estimate_tier (SC-004/SC-005/SC-006). - Imports the AISOS-2444 domain core (model_tier, model_tier_estimator, model_tier_ownership) rather than reimplementing estimator/ownership/label logic. - Added src/forge/prompts/v1/model-tier-comment.md for the comment body template. All 16 RED tests in test_tier_labeling.py now pass (GREEN); no regressions in the jira/models unit suites.
