Beacon-derived TWT session clock checkpoint on ns-3.48

Local acceptance: 1179 Debug cases and 390 native address/undefined/leak sanitizer cases passed. Seven normal and three sanitizer MU profiles, 21 bounded-input checks, both executor probes and 100 standalone mapper checks also passed.

Scope: opt-in capture of current associated-Beacon clock evidence for explicit ordinary individual single-link session start. Missing or expired evidence is rejected before ownership allocation. Automatic distributed TSF synchronization, clock drift/epoch inference, autonomous recovery, protected/broadcast TWT and MLO/EMLSR execution remain unsupported.

The simulator source tree is 78d417aeb; the tagged child changes only acceptance documentation.

Associated-Beacon TWT clock observation checkpoint on ns-3.48

Acceptance: 1177 Debug cases, 388 sanitizer cases, both legacy physical probes, seven MU profiles, three sanitizer MU profiles, 21 bounded invalid-input checks and 100 mapper checks.

Scope: read-only versioned clock evidence for one associated single-link QoS HE STA. The observer never infers hardware synchronization or autonomously mutates agreements, sessions or executors.

Explicit STA consent for AP-originated TWT execution on ns-3.48

Local acceptance: 1169 QUICK cases in 28 suites, nine physical profiles, 21 invalid inputs and 100 mapper checks. Isolated address/undefined/leak acceptance: 380 cases in 15 suites and three physical MU profiles, without suppressions.

Scope: explicit shared paired single-link HE/QoS execution after exact opted-in physical receipt, caller STA consent and AP native ACK, with fixed deadlines and exact requester/action/executor ownership. Packet UID and local generations are simulator metadata.

Scope: reusable configurable native RR MU probes and two zero-TXOP recovery corrections. Existing explicit single-link TB/non-TB execution remains supported. No AP-initiated unsolicited installation, autonomous distributed confirmation, automatic TSF synchronization, protected/broadcast TWT, MLO/EMLSR TWT execution, hardware calibration or full-frame containment is added.

Checked individual wire TB session checkpoint on ns-3.48

Local acceptance: 1099 QUICK cases across 26 suites, both physical probes and 100 mapper checks passed. An isolated native address/undefined/leak sanitizer build passed 310 selected cases across 13 suites without suppressed diagnostics.

Scope: individual implicit unannounced unprotected TB/non-TB proposals and caller-clock shared Accept-plus-AP-ACK paired installation. Strict Demand preserves raw timing and Trigger. Six physical wire MU cases include fallback, Teardown, mixed flows and real ACK loss. Relay event reference cycles and empty malformed packet construction are corrected. Autonomous distributed confirmation, AP-initiated unsolicited installation, automatic TSF synchronization, admission, protected/broadcast TWT, MLO/EMLSR execution, hardware calibration and full-frame containment remain unsupported.

Fixed-state native TB/OFDMA energy checkpoint on ns-3.48

Acceptance on Ubuntu and an independent Debug build: 1088 QUICK cases in 26 suites, two physical probes and 100 mapper checks. Nineteen MU cases independently account for every STA; allocation caps 1/2/4 and alternate voltage/current/update parameters are covered.

Scope: local unannounced single-link HE/QoS execution with native RR gating and fixed-state energy accounting. Wire TB installation, automatic TSF synchronization, protected/broadcast TWT, MLO/EMLSR execution, admission, hardware calibration, RU-dependent currents and full-frame containment remain unsupported. The published extension and three source lineages were audited; no code from those snapshots was imported.

Local trigger-based TWT MU scheduling checkpoint on ns-3.48

Local acceptance: 1085 QUICK test cases across 26 suites, two physical probes and 100 mapper checks passed on both validated builds. All 29 required log hashes and frozen code/test/build sources were verified; only three documentation files changed after testing.

Scope: explicitly configured unannounced single-link HE/QoS TB agreements gate native RR UL solicitation and DL MU eligibility, with protection rechecks and pending SIFS/ACK/BA lifetime handling. Wire/session TB installation, automatic TSF synchronization, autonomous distributed confirmation, broadcast/protected TWT, MLO/EMLSR, full-frame containment and TB energy acceptance remain unsupported.

Native TWT energy accounting checkpoint on ns-3.48

Local Ubuntu acceptance: 932 QUICK test cases, two physical probes and 100 mapper checks passed; the existing basic energy example passed. MLO loss injection is corrected and all 568 baseline MLO cases are required.

Scope: prior shared single-link AP/STA session control plus independently checked native radio/source energy accounting with caller-configured fixed currents. Basic source arithmetic preserves fractional joules. Hardware calibration, automatic TSF synchronization, autonomous distributed confirmation, trigger/OFDMA execution, complete groupcast, TWT MLO/EMLSR and full-frame containment remain unsupported.

Shared individual TWT session-control checkpoint on ns-3.48

Ubuntu acceptance: 311 test cases, two physical probes and ten fresh-process mapper checks with 100 exact arithmetic assertions passed.

Scope: opt-in shared AP/STA control with explicit common TSF reference, matching requester Accept and retained-response ACK evidence, and version-owned lifecycle cleanup. No autonomous distributed negotiation or automatic TSF synchronization. Trigger-based/OFDMA execution, complete groupcast, MLO/EMLSR, calibrated energy and full-frame SP containment remain unsupported. Earlier MLO regression remains under investigation.

Bounded individual TWT responder checkpoint on ns-3.48

Local acceptance: 245 test cases, both physical probes and ten native-resolution mapper processes passed. 50 new responder cases cover bounded retention, conflicting tokens, capacity, response and ACK loss recovery, owned queues and lifecycle cleanup.

Scope: immutable AP response or silence retention and exact duplicate replay on one associated QoS HE link, with fixed expiry, bounded capacity and version-owned response cleanup; prior explicit clock mapping and paired executor APIs remain available. No autonomous requester retry, delayed AP response, admission, negotiated executor installation/removal or automatic TSF synchronization is added. Protected/broadcast TWT, MLO/EMLSR, OFDMA, full-frame containment and energy validation remain unsupported. Finite retention cannot exclude arbitrarily late identical input; in-flight exchanges may finish after removal. The earlier MLO regression remains unresolved; see doc/twt/REGRESSION_STATUS.md.

Explicit TWT timing and shared-control executor checkpoint on ns-3.48

Local acceptance: 195 test cases, both local-execution probes and ten native-resolution mapper processes passed. Actual Setup/Accept/ACK tests cover bidirectional data, controlled response and ACK loss, MAC retries and explicit lifecycle cleanup.

Scope: caller-reference TSF mapping and explicit paired installation/removal for supported ordinary individual unannounced single-link HE/QoS agreements, with version-owned compensation. Autonomous negotiated execution, automatic TSF synchronization, AP admission and duplicate recovery, protected/broadcast TWT, MLO/EMLSR, OFDMA, energy validation and full-frame containment remain unsupported. The earlier MLO regression remains unresolved; see doc/twt/REGRESSION_STATUS.md.

Checked individual TWT MAC action transport checkpoint on ns-3.48

Scope: ordinary individual actions on one associated QoS HE link, STA requester state and synchronous AP response metadata. Accept does not install executor agreements; Teardown does not automatically remove executing agreements. Coordinated execution, automatic TSF mapping, admission, application-level duplicate recovery, protected/broadcast TWT, MLO/EMLSR, OFDMA, energy validation and full-frame SP containment remain unsupported. An earlier MLO regression remains unresolved; see doc/twt/REGRESSION_STATUS.md.

Requester individual TWT Setup transaction checkpoint on ns-3.48

Local acceptance: 107 test cases and both physical probes passed; 30 cases cover requester correlation, deadlines, token reuse and lifecycle cleanup.

Scope: requester transaction state, checked wire codecs and local single-link AP/STA execution. MAC action integration, AP responder policy, coordinated installation, automatic TSF mapping, optional/broadcast/protected codecs, MLO/EMLSR, OFDMA, energy validation and full-frame SP containment remain unsupported. A finite token reuse guard cannot exclude arbitrarily late identical responses. The earlier MLO regression remains unresolved; see doc/twt/REGRESSION_STATUS.md.

Individual TWT wire-codec checkpoint on ns-3.48

Local acceptance: 77 test cases and both physical probes passed; 18 cases cover byte layouts, bounded parsing and explicit timing conversion.

Local acceptance: 45 test cases passed; announced UL probe recorded 38 DATA PSDU starts inside SPs and zero outside.

Scope: local agreements on one associated QoS link. Negotiated TWT, complete unannounced AP delivery, MLO/EMLSR execution and full-frame SP containment remain unsupported. An additional MLO regression remains unresolved; see doc/twt/REGRESSION_STATUS.md.

TWT executor prototype on ns-3.48

Local validation: 9 wifi-power-save cases passed; announced UL probe passed with 40 DATA PSDU starts inside SP and zero outside.
